Attitudes of Dutch general practitioners, pediatricians and gynecologists
towards cystic fibrosis carrier screening
M. J. H. Baars, L. Henneman, M. C. Cornel, L. P. Ten Kate;
VU University Medical Center, Amsterdam, NETHERLANDS.
Objective To investigate attitudes of general practitioners (GPs),
pediatricians (PEDs) and gynecologists (GYs) towards cystic fibrosis (CF)
carrier screening and to determine factors influencing these attitudes.
Methods A questionnaire developed by Hofman et al (Acad Med 1993; 68:
625-32) containing questions about knowledge and attitudes towards genetics
(tests) was adapted to the Dutch health care system. Questionnaires were sent
to randomly selected GPs (n=200), GYs (n=300) and PEDs (n=265). Multiple
logistic regression identified predictors of positive attitudes towards CF
carrier screening.
Results The response rate of GPs, GYs and PEDs was 64%, 69% and 72%,
respectively. Of the respondents 63% of GPs, 69% of GYs and 71% of PEDs agreed
that couples should be tested if they ask for it. Of the respondents 32% of
GPs, 40% of GYs and 32% of PEDs favored routine screening when a hypothetical
error free inexpensive test would be available. However, after explaining
limitations in the test sensitivity (95% detection rate for individuals) these
percentages decreased to 16%, 19% and 25%, respectively. Predictors for
offering routinely CF carrier screening in the latter situation were [OR
(95%CI)]: considering the test sensitivity less important (GPs: [4.2
(1.4-12.3)]; GYs [6.2(1.9-20.7)]), high perceived risk of having a child with
CF (GYs: [4.0 (1.2-13.9)]), providing genetic counseling (PEDs: [4.2
(1.2-15.0)]) and reassurance when both partners test negative (PEDs: [4.3
(1.6-11.8)]).
Conclusion Although approximately two-thirds of physicians support
performing CF carrier screening when couples ask for it, more reservations are
present among these physicians for routinely offering CF carrier screening.

Feasibility and acceptability of two screening strategies for
haemochromatosis, report of phase one of a randomised controlled trial.

UNITED KINGDOM, 2Division of Inflammation, Infection and Repair,
University of Southampton, Southampton, UNITED KINGDOM.
Haemochromatosis, a treatable, adult-onset condition of progressive iron
overload is amenable to screening. Initial enthusiasm for screening to
increase early diagnosis has been modified since the identification of the HFE
gene. The risk of disease attributable to the at-risk genotypes, and disease
progression in those diagnosed is not established. Screening trials will
identify individuals in whom these questions can be evaluated. Evaluation of
these programmes should include evaluation of sensitivity and specificity and
all the components of the programme e.g. uptake, population characteristics
and effectiveness of treatment.
Design: Randomised controlled trial of two screening strategies.
a) Biochemical screening for iron overload followed by genetic analysis and
clinical assessment
b) Genetic screening for the at risk genotype followed by biochemical testing
for iron overload and clinical assessment.
Sample: General practice population aged 30-70 stratified by age and
sex
Findings: 1438 individuals were invited; initial acceptance was
approximately 30%. Uptake was higher in females than males, specifically in
older females. Middle-aged men who would be expected to have a higher risk of
expressing the at-risk genotypes were less likely to accept the offer of
screening.
The allele frequencies for the haemochromatosis associated alleles were
greater than would be expected from previous population studies.
Discussion: In this pilot of population based screening in primary
care, the low uptake of screening and the characteristics of the population
that accepted screening have implications for the design of treatment or
screening trials for haemochromatosis that merit further investigation.

Coping strategies of pregnant women after "triple-diagnostic" and
those of their partners
S. Jahn, F. R. Kreuz;
Technical University, Dresden, GERMANY.
Objective: To compare coping strategies of pregnant women after the
triple-diagnostic and of their partners. To point out the importance of the
genetic counselling. Background: The triple-diagnostic has become a
standard prenatal screening-method and involves a combination of three serum
parameters with personal data to define the individual’s probability for a
fetal trisomy 21. This screening often takes place without giving sufficient
information. A "bad result’ is mostly equated with a handicapped child.
Methods: Our investigation was carried out by questionnaires. The
answers of 92 women after "triple-diagnostic’, genetic counselling and
prenatal diagnosis and of 52 of their partners were evaluated. Results:
Only 2/3 of the women were given information about this screening-method by
their gynaecologist. A quarter of the partners had been informed by their
wives or by the gynaecologist. Half of them had received this information only
at genetic counselling. After a pathological triple test, 86% of the pregnant
women and 90% of their partners felt depressed; 2% felt activated. After
genetic counselling, there was a significant increase to the activated mood
(women: 52% were depressed, 34% felt activated; partners 58% and 40%). The
coping strategies showed the most significant variation in active coping:
after risk information, women 17%, partners 10%, and after prenatal diagnosis,
55% and 45%. 25% of the pregnant women refused invasive prenatal diagnosis
after genetic counselling. Conclusion: Genetic counselling plays an
important role in the development of positive coping strategies. It should
provide information and therapeutic support for pregnant women and for their
partners.

Serum screening uptake and attitudes towards Down's syndrome
L. D. Bryant, J. M. Green, J. Hewison;
University of Leeds, Leeds, UNITED KINGDOM.
Prenatal screening for Down‘s syndrome is now offered in some form to most
pregnant women in the UK. However, very little is known about the attitudes
that women hold towards Down‘s syndrome and how such attitudes may influence
screening choices. This paper presents findings from a study based in an
antenatal clinic in the north of England where serum screening was offered to
all women attending for antenatal care. Over a six-month period, women in the
first trimester of pregnancy were asked to complete a questionnaire that
incorporated measures of cognitive, emotional and experiential aspects of
attitudes towards Down‘s syndrome. An objective measure of the participants‘
serum screening uptake was then collected at a later date from patient
records. The findings suggest that regardless of attitude towards Down‘s
syndrome most women accept screening tests. All of the women with the most
unfavourable attitudes towards Down‘s syndrome accepted screening as did 67%
of those with the most favourable attitudes - despite the latter group holding
unfavourable views towards termination for the condition. The findings have
implications for the issues of informed choice and the perceived ‘routineness‘
of prenatal screening tests.

Thalassaemia carrier testing in pregnant Pakistani women: perceptions of ‘information’
and ‘consent’.
S. Ahmed, J. Green, J. Hewison;
University of Leeds, Leeds, UNITED KINGDOM.
Introduction: The literature on genetic testing suggests that one of the main
objectives of screening programmes is to allow individuals to make informed
decisions. However, there is no published research on whether women value
informed consent for antenatal thalassaemia carrier testing.
Aims: To ascertain pregnant Pakistani women’s perceived value of ‘informed
consent’ for antenatal thalassaemia carrier testing and their perceived
pre-test information needs.
Methods: In study 1, 110 Pakistani women tested and not found to be
thalassaemia carriers completed a questionnaire, 14 of whom were also
interviewed. In study 2, 36 women identified as carriers/possible carriers
completed a questionnaire and were interviewed. The questionnaires assessed
women’s knowledge and understanding of antenatal tests; their attitudes
toward antenatal care and tests for fetal abnormality; their knowledge and
understandings of thalassaemia; and their pre-test information preferences.
The interviews explored these domains in more depth and investigated women’s
beliefs about ‘informed consent’.
Findings: Women had received little or no pre-test information and said that
they would have preferred to be informed that they were being tested for
thalassaemia carrier status, but they did not expect, or express a desire, to
be asked for their ‘informed consent’ for antenatal thalassaemia carrier
testing.
Discussion: While women wanted pre-test information in order to be ‘informed’
of antenatal thalassaemia carrier testing, they were less concerned about
being asked for their ‘consent’. This finding is discussed in the context
of the way in which service delivery is organised.

Breast cancer: South Asian patient's experience, attitudes, beliefs and
perception of risk.

Centre for Research in Primary Care, Leeds, UNITED KINGDOM.
Breast cancer: South Asian patients‘ experience, attitude, beliefs and
genetic perception.
Karbani, G.A., Chu,C., Hewison, J. and Atkin, K.
Background: Incidence of breast cancer among South Asian women living
in the UK is increasing. We know little about how these women make sense of
the condition or how health care services can best support this patient group.
Aim: The study aims to examine health care pathways, attitudes, beliefs
and genetic perception of risk factors in South Asian women with breast cancer
compared with ‘white‘ women.
Method: The study comprised of two groups of women attending breast
clinic because of a diagnosis of breast cancer. The study comprised 25 South
Asian and 15 'white' women' diagnosed with breast cancer, matched for
diagnosis, age, and socio-economic class. This enabled us to explore the role
of ethnicity in mediating women‘s responses to the illness. For further
context, our work also included the experience of the women's main family
carer (n=29) and a health professional involved in their care (n=15).
We collected information using semi-structured qualitative interviews, which
were then subject to detailed content analysis.
Findings: The main themes emerging from the analysis include access to
service delivery, knowledge of breast cancer, health beliefs, coping
strategies, cultural beliefs regarding genetic and other causes of breast
cancer, communication about the condition within the family, and the role of
health professionals in offering support. The presentation will conclude by
exploring how culturally sensitive provision would improve the care of women
with breast cancer.

Genetic Testing for Hearing Impairment- Different Motivations for the Same
Outcome

Medicine, Sackler School of Medicine, Tel-Aviv University, Tel-Aviv, ISRAEL, 3Speech
and Hearing Center, Hadassah Hebrew University Hospital, Jerusalem,
ISRAEL.
The recent discoveries of genes involved in hearing impairment opens new
options for families and individuals with hearing impairment, but also raises
new ethical dilemmas. Our study aimed at evaluating the intensions, as well as
the reasons, of Israeli Jewish parents of hearing impaired children to opt for
or against genetic testing and prenatal diagnosis for deafness. Questionnaires
were filled by 139 parents, showing a very high interest (87%) in genetic
testing, and lower interest (49%) in prenatal diagnosis. Althogh part of the
Jewish population in Israel do not comply with genetic services, due to
religious restrictions, the high interest in testing was found across all
religious sectors (secular, traditional, orthodox and ultra-orthodox);
however, some of the reasons for undertaking such a test were very different
between the sectors. We conclude that genetic testing would be welcomed by
parents from a wide range of communities, including those which usually do not
apply for genetic counseling and testing, if it is offered in accordance with
their cultural norms and beliefs.

Uses of the body and informed consent for participants in predictive medicine
research
P. Ducournau;
INSERM U558, Toulouse, FRANCE.
On the occasion of the creation of a DNA bank for research in predictive
medicine in the south of France, this sociological study deals with an ethical
and juridical norm and its application: the principle of free and informed
consent of DNA donors-participants. This consent is often said to favour the
expression of the patients' "autonomy" towards "medical
power": it would make sure that individual freedom in the uses of the
body is put in confrontation with the biomedical enterprise. Previous studies
have addressed the question of the quality of the consent given by
participants. This study rather addresses the way in which they
"frame" the consent (they give a meaning and their position in
relation to this meaning). Not only their position regarding the procedure but
also that towards the concept of consent itself are investigated. The access
to this framing is achieved through thorough interviews (planed number = 50).
This speech on consent is then mirrored with the participants' uses of the
body (or elements issued from the body): these uses are apprehended here
through the meaning given by the DNA donors to their involvement in research.
The first results show different typologies of the body usage: the body
submitted to medical activity, the body medically auto-supervised and
"property" of the individual or also the body subjected to
collective interests. I will try to show that these modalities of use involve
different ways of understanding and of using the principle of informed
consent.

Am I My Brother’s Keeper?: Outlining Rights and Responsibilities in the
Context of the Human Genome Diversity Project
J. K. Brewer 1,2;
1Harvard University, Cambridge, MA, 2De Paul College of
Law, Chicago, IL.
CONCLUSION AND IMPACT
There are many obstacles to continued scientific research, the Human Genome
Diversity Project (HGDP) specifically. The main obstacles appear to be
differing philosophies toward human rights and responsibilities. On the one
hand, Western researchers impute ownership rights upon human body parts. This
view is repugnant to the culture and beliefs of many indigenous people.
However, indigenous peoples and some Western legal scholars maintain that a
duty exists for individuals to further the survival of others through
scientific research. Still, this duty conflicts with a duty that may exist to
future generations not to tinker with the common heritage. The issue of human
genetic diversity presents an interesting paradox: genes are responsible for
one’s uniqueness, and simultaneously, genes are an omnipotent component of
every human being. Achieving a balance between preserving the integrity of our
genetic heritage and granting ownership rights in furtherance of scientific
knowledge is a perplexing challenge. Yet, at least one group of indigenous
peoples has achieved such a balance, and they justified their agreement by
articulating a duty to others to help understand and cure a particular
disease. Perhaps if we all recognize that we are our brother’s keeper, we
can work together to further the aims of science while at the same time
maintaining respect for proud cultures.

Huntington Disease (HD) is a genetic, chronic, neurodegenerative disorder for
which there is no known cure. In the past, rehabilitation in HD was justified
on humanistic compassionate ground but now it has a more scientific fundament
and theoretical support in recent studies using animal models that show
beneficial effects of environmental stimulation on disease progression and
suggest a possible positive impact of environmental factors on individuals
affected by HD.
A pilot research project on the evaluation of rehabilitation effects in HD has
been started in Italy in 1999. Fifty patients with a clinically and
genetically confirmed diagnosis of HD have been enrolled in a rehabilitation
protocol including neuromotor and cognitive therapy. Patients' conditions were
assessed at patients' admission and discharge. Further additional data were
collected from patient's and families' interviews. First results are
encouraging because we can remark notable improvements both on motor control
and psychological conditions and we have also found positive effects on family
relationships and on caregivers well being state.
Analyses of data are currently performed.
The research was made possible by a grant from C.N.R to M.F.

predisposition

Marsden NHS Trust, London/Sutton, UNITED KINGDOM.
Individuals who have a genetic test for breast/ovarian cancer predisposition
are required to pass on information to their relatives. The purpose of this
study is to explore communication in the family about cancer and predictive
genetic testing for breast and ovarian cancer predisposition amongst women at
increased risk of developing breast and/or ovarian cancer due to their family
history. 15 women attending the RMH Genetics Clinic were recruited into the
study. They were interviewed at least one week prior to receiving their
BRCA1/2 test result and again 6 months following the test result. A grounded
theory approach was adopted to analyse the interview transcripts. The findings
indicated that cancer or deaths had affected family relationships, with some
relationships being strengthened and others becoming distant. Many women had
talked to other family members about testing. Women anticipated being
selective in which family members they would tell about their test result.
Several women experienced difficulty in talking to relatives about their test
result. The findings illustrate that the nature of relationships and differing
opinions within the family regarding genetic testing are likely to have an
impact upon dissemination of information about predictive testing to
relatives.

Myotonic Dystrophy and the marital relationship
A. Rotteveel, A. R. Wintzen, A. Tibben;
Leids Universitair Medisch Centrum, Leiden, NETHERLANDS.
Background: Myotonic Dystrophy (MD) is a multi-system disease with
symptoms including muscle weakness, especially in facial muscles and distal
extremities, cardiac and gastro-intestinal problems. Cerebral symptoms of MD
include (daytime) sleepiness, loss of energy, mental slowness and lack of
initiative. Some studies suggest a change of personality. Based on clinical
findings 3 phenotypes have been identified: mild, classical, and congenital.
MD is inherited in an autosomal dominant manner. Offspring of an affected
individual have a 50% chance of inheriting the causal mutation.
These symptoms not only affect the patients’ life but also that of their
spouses. Couples seem to respond to this variety of symptoms in different
ways. Some apparently cope with these problems and go on living their (more or
less adjusted) lives. Others express having trouble in doing so and keep
experiencing this trouble for a prolonged period of time.
Objectives:
1. How does MD influence the lives and relationships of patients?
2. Which factors contribute to people’s ability to overcome the problems
caused by MD?
Methods: 100 patients of the outpatient clinic and their partners are
interviewed about their relationship and the way they feel it has been
affected by MD. Information on present symptoms of MD, personality, coping
style, family functioning, anxiety and depression is obtained through
questionnaires. While subjects watch funny pictures, facial expressiveness is
assessed by experienced judges.
Results: Until January, 57 patients (58% males) and their partners (40%
males) have enrolled. Mean age 46,5 years (sd = 8,8).

Putting HD into words: exploring the virtual narratives of the Italian HD
support group online.
G. Jacopini 1, P. Zinzi 1, A. Cordi 2;
1Institute of Psychology C.N.R., Rome, ITALY, 2A.I.C.H.-ROME,
Rome, ITALY.
Three years ago the Italian Association for Huntington's Disease
(A.I.C.H.-ROME) has developed a web site. It is a non commercial service and
is the result of patients'and caregivers' voluntary work. In Italy it is the
unique "interactive" website for HD.
Beyond any expectation, this virtual community interested to/involved with HD
for many different reasons has been growing very rapidly: from 6 contacts a
week, when the site was started, up to 1600 contacts in one month (November
2001).
Many messages have arrived: some messages are brief and simply ask for
information, other messages are rather long and are aimed at sharing the
intimate, emotional aspects of the individual's experience of the disease or
at confronting with others about main life decisions such as to be tested or
not, having or not children, having or not prenatal diagnosis, informing or
not children about the disease in the family and so on.
These exchanges on line offer a unique opportunity of a glimpse to the heart
of a support group for a severe, incurable, hereditary disease. A text
analysis and a qualitative examination of the messages are currently
performed. Our first inquiries are aimed at: providing a description of this
virtual community; analysing the priorities given by the contributors to the
different issues; exploring the way they communicate their ideas and emotions
about the disease.

Adult Survivors of child sex abuse in the genetic counselling
consultation
C. A. Falconer;
St James University Hospital, Leeds, UNITED KINGDOM.
Given the prevalence of sexual abuse in our society, with a large proportion
of the abuse taking place within families, it is clear that any health
professional will be dealing with clients who are survivors of childhood sex
abuse.
This paper explores how a pre history of childhood sexual abuse may impact the
genetic counselling consultation. The genetic counselling situation is
possibly the only one in which taking a family tree is such a large part of
the consultation. It can expose people to thinking about their relationships
within the family and bring forward painful memories. A faulty gene running
through the family can highlight the legacy of abuse or the 'inheritance' of
the problems associated or passed on with it.
Implications for genetic counsellors discussed in this paper are:
Disclosure of sexual abuse.
The specific genetic implications of incest.
Non disclosure of genetic information to family members because of a history
of abuse.
Occasional cases of 'munchausens syndrome' particularly where prophylactic
surgery may be considered have been reported.Could some of these women have
been sexually abused?
One of the predictors of abnormal grief reaction following termination of
pregnancy is incest and sexual abuse. As genetic counsellors we are often
supporting women in this situation.

Centre, Rotterdam, NETHERLANDS, 2Family Cancer Clinic/Daniel den Hoed
Clinic, Erasmus Medical Centre, Rotterdam, NETHERLANDS, 3Department
of Public Health, Erasmus Medical Centre, Rotterdam, NETHERLANDS.
Background: The MRISC study is a surveillance program for women at risk of BC
due to a genetic predisposition or family history. Surveillance consists of
bi-annually physical examination and yearly mammography and MRI-scan. The
estimated actual risk of developing BC in terms of a cumulative life time risk
(CLTR) is trichotomiseda. Category 1 implies a CLTR of 60-85%, 2: 30-50%, and
3: 15-30%.
Objectives: Identify (a) the relation between CLTR, coping strategies and
psychological distress; (b) the relation between risk of developing BC as
perceived by the participant (adjusted for CLTR), coping strategies and
psychological distress.
Methods: Participants completed a questionnaire 2 months prior to their
surveillance appointment, containing: the Hospital Anxiety and Depression
Scale, the Impact of Event Scale, the Psychological Consequences Questionnaire
and the Utrecht Coping List. The participants perceived risk was measured in
terms of cognition and affect.
Multiple linear regression and polychotomous ordered logistic regression
analysis were used to identify the relationships between actual and perceived
risk on the one hand and psychological factors on the other.
Results: 241 women answered their baseline questionnaire (mean age 40 years).
11% belong to category 1, 53% to category 2 and 36% to category 3.
CLTR is positively related to avoidance and negative psychological
consequences (p< 0.05). Perceived risk is positively related to a
depressive coping style (p < 0.02).
Conclusion: Having a higher CLTR means displaying more avoidance and
experiencing more negative psychological consequences. Women perceiving their
risk of developing BC as high display a depressive coping style.

The meaning of risk: Women's perceptions of the genetic risk of breast and
ovarian cancer following BRCA1/2 mutation searching

KINGDOM.
The literature suggests that there is a divergence between the ways in which
individuals with a family history of breast/ovarian cancer perceive their
risks of developing cancer and the risk estimates provided by clinicians.
However, there has been little research that explores the meaning of risks for
individuals who are deemed at risk because of their family history, and none
that has looked at how women who have previously been affected with cancer
make sense of their (potentially) increased risks following DNA-testing.
This retrospective study of affected women who had undergone BRCA1/2 mutation
searching investigated their perceptions of developing cancer. In-depth
interviews were undertaken with 30 women. These explored their risk perception
and the impact of genetic testing on their risk perception.
The data suggest that following their initial diagnosisall women were very
aware of their recurrence risk. However, most reported that their anxiety
about developing cancer had decreased over time. For some the probability of
developing cancer was perceived as reducing over time, whilst others described
their risk of cancer as constant but their ability to accommodate risk within
their lives changed. Women's understanding of their (potential) inherited risk
of cancer involved reconciling their previous experiences with their
expectations of the future. Thus, some women, did not regard genetic risk as a
threat, whilst others reported an increase in anxiety on learning their risks
of developing a second primary cancer. The implications of these findings for
theoretical accounts of risk perception will be discussed.

The objective of this study was to describe medical and social interactions
about BRCA genetic testing and how helpful they were perceived by the patients
during the cancer genetic testing process.A prospective cohort study is
ongoing including all women who attended at one French cancer genetic centre
after a first biological sample was analysed for mutation identification
(BRCA1/2). Closed questionnaires were administered before and after the
occurrence of the 2nd cancer genetic consultation. This consultation aims to
confirm the decision to be tested. No biological results were given during
this consultation.Preliminary results were analysed (N=82 ; mean age 46,
SD=11; 70% affected by cancer). The medical providers consulted about the
decision to be tested were: the Cancer Geneticist (82%), the
Gynaeco-Obstetrician (44%), the General Practitioner (42%) and the Clinical
Psychologist (7%). When they occurred, these encounters were considered
helpful by 92%, 75%, 67% and 62% for Cancer Geneticist, Clinical Psychologist,
Gynaeco-Obstetrician and General Practitioner respectively. In the family,
spouses and sisters were consulted in 40%, and mothers in 26%. These
encounters were considered helpful in 76%, 60%, and 44% for sisters, mothers
and spouses respectively. All the sources consulted were in their overwhelming
majority favourable to genetic testing. An analysis of medical and
psychological factors related to information exchange and information seeking
will be investigated further.These results highlight the need for education in
cancer genetics, not only for primary care providers but also for the social
network of those concerned by genetic testing.

Theory of Engagement: A model for predictive test counselling
M. McAllister 1, A. Silver 2, G. Evans 3;
1Regional Genetics Service and Academic Group of Medical Genetics,
Manchester, UNITED KINGDOM, 2Oxford Regional Genetics, Oxford, UNITED
KINGDOM, 3Regional Genetics Service and Academic Group of Medical
Genetics, St Mary's Hospital, Manchester, UNITED KINGDOM.
The theory of engagement emerged from grounded theory work with HNPCC families
having predictive genetic testing (McAllister, 1999; 2001), and differs from
existing general psychological theories because it is grounded in the
experiences of high risk families, and makes specific predictions about
adjustment to the results of predictive genetic testing. According to the
theory, it is not test result per se, but prior engagement status in
combination with test result that predicts post-test adjustment. Intense
engagement prior to predictive testing is associated with feelings of relief,
and often satisfaction with the discovery of mutation carrier status in HNPCC
families. These mutation carriers may feel that they are better off than
members of the general population because their carrier status is perceived as
a gateway to care. These feelings are not always shared with their less
engaged relatives. A proposed model for pre-test counselling for cancer
predisposition is presented that may enable more appropriate targeting of
clinical resources, cost-effective practice, and the likelihood of decreased
patient distress and increased patient satisfaction. It may also prevent
future difficulties in adjusting to predictive test results.

Impact of predictive genetic testing for hereditary non-polyposis colorectal
cancer (HNPCC)

of Wales Hospital, Randwick, AUSTRALIA, 3Genetic Health Services,
Victoria, AUSTRALIA.
Background
This longitudinal multi-centre Australian study examined the response of
people at high risk for colorectal cancer to predictive genetic testing for
hereditary non-polyposis colorectal cancer (HNPCC). There were four assessment
times of participants: prior to, and 2 weeks, 4 months and 12 months after
notification of test result.
Results
104 people have completed the baseline questionnaire, of whom 56 are female
and 45 male. Almost all have received genetic test results and also completed
the second questionnaire, 88 completed the third and 76 the fourth.
Measures of anxiety, depression, and intrusive and avoidant thoughts about
being at risk for colon cancer (as measured by the Impact of Events Scale
[IES]) were included in the questionnaires. Results show marked differences
between carriers and non-carriers two weeks post notification, particularly
for the IES measure. The difference between these two groups for IES scores
remained statistically significant at 4 and 12 months post testing, having
adjusted for age and baseline levels of IES. However, all measures decreased
between time 2 (two weeks after the result was given) and 12 months for both
groups.
Most non-carriers appear reassured and did not have colorectal cancer
screening in the first year post genetic testing: 12% of non-carriers have had
a colonoscopy, compared with 58% of carriers.
Conclusion
At this stage, there is no evidence that having a predictive test for HNPCC is
causing psychological distress and compliance with advice related to screening
is being observed.

This longitudinal study aimed to document i) the information-giving and
patient-communication styles of clinical geneticists and genetic counsellors
(consultants) in familial breast cancer clinics, and ii) assess the impact of
these behaviours on women’s knowledge, whether their expectations were met,
satisfaction, risk perception and psychological status.
158 women from high-risk breast cancer families completed self-report
questionnaires at two weeks pre-and four weeks post-consultation. The
consultations were audiotaped, transcribed verbatim and coded.
Multivariate logistic regressions showed that women who had prophylactic
mastectomy (p=0.00) and oophorectomy (p=0.01) discussed had significantly more
expectations met and a greater reduction in breast-cancer-related avoidant
thoughts (p=0.07 and p=0.09 respectively). Women who received a summary letter
of the consultation and reported reading it, experienced significantly lower
generalised anxiety (p=0.01), lower breast cancer specific anxiety (p=0.08)
and were significantly more likely to be accurate in reporting their perceived
risk (p=0.02). Women whose consultant used more supportive behaviours
experienced significantly more breast-cancer-related intrusive thoughts at the
four weeks follow-up (p<0.001). Women who received more supportive
behaviours were not significantly more anxious before to genetic counselling.
Discussing prophylactic surgery led to better psycho-social outcomes.
Providing women with a letter summarising the consultation reduced anxiety,
increased accuracy of risk perception and was a useful adjunct to the
consultation. Greater use of supportive and counselling behaviours appeared to
increase intrusive thoughts, at least in the short term. Longer follow-up may
have shown a reduction in emotional response. Identifying methods to assist
consultants to effectively address emotional issues may be helpful.

Attitudes of persons at risk for late-onset neurodegenerative disorders and
for hereditary cancer diseases towards molecular genetic predictive
diagnosis
F. R. Kreuz, M. Aehnelt;
Technical University, Dresden, GERMANY.
Objective: To compare the attitudes of persons at risk (RP) towards
genetic predictive diagnosis (PDD).
Background: Huntington’s disease (HD) and heredoataxias (HA) are
late-onset neurodegenerative disorders with (HD) and without (HA) dementia.
Both are incurable. Hereditary cancer diseases (HC) can be prevented by
prophylactic methods. DNA analysis is available.
Methods: Our investigation was carried out by questionnaires. Answers
from 300 RP for HD, 30 for HA and 55 for HC were evaluated.
Results: About 55% of RP for HD, 73% for HA and 85% for HC wish to
undergo PDD. The main reasons are to obtain certainty about risk status (HD:
78%), to plan for the future (HA: 68%) and to obtain prophylactic therapy (HC:
80%). 33% of the RP for HD, 13% for HA and only 4% for HC refuse PDD. The main
reasons against PDD are psychological problems (HD: 79%; HA, HC: 50%). 2/3 of
the RP for HD, 1/3 for HA and only 1/5 for HC think that there are problems in
taking PDD generally. Most problems are seen in coping with the result of PDD
(psychological problems; HD: 77%; HA: 60%; HC: 45%), with insurance companies
(40%, 20%, 55%) and with social surroundings (36%, 20%, 18%). Psychotherapy
would be accepted by 93% (HD), 83% (HA) and only by 25% of RP for HC.
Conclusions: There are different attitudes towards PDD in the three
groups because of the different symptoms and the possibilities of preventing
in the case of cancer. Genetic counselling has to consider these features.

Deafness is the most frequent sensorial defect. One in a thousand children
present with profound deafness at birth. As this handicap affects
communication, deafness impedes language acquisition, speech development and
social integration. The particularity of this handicap is the existence of a
deaf community with their own language and culture. The recent progress in the
identification of the genes responsible for isolated deafness have open new
technical possibilities and pose significant ethical problems. We send
questionnaires to hearing parents of deaf children and to deaf adults. The aim
of these questionnaires is to discover if patients know the etiology of their
deafness, if they want to know it, if they have access to a genetic
counselling consultation and if not why, what are their thoughts about the
possibility to pratice antenatal diagnosis, and therapeutic abortion. We
analyse more than 200 responses. We try to determine if the reponses are
influenced by the audiologic status of the responder, the severity of the
defect, its association with an other handicap or others parameters.

Some familial forms of dementia were found to be transmitted as mendelian
traits, such as early onset Alzheimer disease and frontotemporal dementia with
parkinsonism, which were associated with mutations in the PS-1 and MAPT genes,
respectively. In these cases, the mutation is characterised by autosomal
dominant inheritance, with high penetrance. Thus, a test with high predictive
value can be offered to the at-risk healthy relatives of patients.
The present study is aimed at: i) evaluating the attitudes towards genetic
testing in relatives of patients with familial dementia; ii) developing a
specific protocol for genetic counselling, including presymptomatic testing,
for families with mendelian forms of dementia.
Thirty-five relatives of patients with familial dementia were recruited.
Participants were tested by an extensive psychological assessment including
several rating scales; the attitudes towards genetic test were evaluated by
using a specific tool (Roberts, 2000). About 70% of participants expressed
probable intentions to seek for the test. Participants reported test benefits
as more important than limitations and risks (p=.0019). Staying on top of
future treatment, as well as planning the future, were considered the most
important items in favour of the test. Psychological and sociodemographic
characteristics do not seem to influence attitudes and intentions towards
genetic testing. Two families in which a MAPT gene mutation segregates with
frontotemporal dementia were identified; some at-risk relatives requested to
be enrolled for the genetic testing procedure. On this purpose, a
multidisciplinary team is developing a pilot protocol for genetic counselling.
The preliminary experience will be reported.

Bipolar disorder is a chronic, mental health condition with a multifactorial,
polygenic aetiology. The illness is characterised by episodes of both mania
and major depression, typically occurring in cycles.
The aim of this exploratory study was to assess knowledge of the possible
causes of bipolar disorder and to discover the level of concern amongst
participants that other family members may be at risk of developing the
illness. 22 adults diagnosed with bipolar disorder were interviewed, using a
semi-structured interview schedule. Data were analysed to see if there was an
emerging difference between those with a family history of mental illness and
those individuals who were isolated cases.
The results showed that 15/22 (68%) knew that family history plays a role,
with 13 then explicitly stating genetics as a cause. 77% cited stressful or
traumatic life-events as a cause of their illness. More than half the sample
overestimated both the population lifetime risk of bipolar disorder and the
lifetime risk for those with an affected parent. There was no evidence that
those with a family history overestimated the risks compared to isolated
cases. Those who overestimated population risk were also overestimating family
risk for developing bipolar illness. Almost half of the sample (10/22) had
experienced some degree of worry about other family members becoming
manic-depressive.
These findings suggest that genetic counselling and information may be useful
to this population.

General Practitioners And Predictive Genetic Testing For Late Onset Diseases:
Their Opinions And Their Perceived Role
M. Welkenhuysen, G. Evers-Kiebooms;
Psychosocial Genetics Unit, Center for Human Genetics, Leuven, BELGIUM.
A sample of 356 GPs received mail questionnaires in combination with telephone
prenotifications and reminders to assess their opinions (1) on the sense of
predictive testing for breast cancer, thyroid cancer, Alzheimer disease and
Huntington’s disease, (2) on the acceptability of testing a child at the
parents’ request and an adolescent at his/her own request, (3) on their own
role in the context of predictive testing. Multiple-choice and open-ended
questions were used. Sixty percent returned the mail questionnaire. One third
of them had at least one patient who had asked for information about a
predictive test and/or who had such a test performed. The following pattern in
the GPs’ judgments about the sense of predictive testing was revealed: the
test for thyroid cancer was considered as more sensible than the test for
breast cancer, both were more sensible than the test for Huntington’s
disease and all three were more sensible than the test for Alzheimer disease.
Predictive testing for Huntington disease for an adolescent at his/her own
request was judged as more acceptable than for a child at the parents’
request. The GPs’ explanations for their judgements will be presented. Six
percent were convinced that GPs have no role at all to play in the context of
predictive testing for late onset diseases. Regarding the type of task, most
GPs focussed on gate-keeping aspects, going from the provision of information,
over making referrals, to being more directive. The research was funded by the
Flemish Interuniversity Institute of Biotechnology (VIB).

Informed choice to undergo prenatal screening: a comparison of two hospitals
conducting testing either as part of a routine visit or requiring a separate
visit
E. Dormandy, S. Michie, T. M. Marteau;
King's College, London, UNITED KINGDOM.
Background:
The wide variation in uptake of antenatal Down syndrome screening is
associated with the method of conducting screening. Uptake is lower when
screening is conducted at a test-specific separate visit compared with a
routine visit. It is not known if informed choice also varies with the method
of conducting screening. Women may find it easier to decline screening if it
is conducted at a test-specific separate visit. Conversely women may find it
easier to accept screening if it is conducted as part of a routine visit.
Aim: To compare rates of informed choice for Down syndrome screening where it
is conducted at a test-specific separate visit or as part of a routine visit.
Participants: 1499 pregnant women offered Down syndrome screening.
Setting: Two hospitals in the UK offering the same Down syndrome screening
test.
Outcome measure: the multi-dimensional measure of informed choice, comprising
three core constructs: knowledge about the screening test, attitudes towards
undergoing the screening test and screening uptake.
Results.
Rates of informed choice to decline screening were the same at both hospitals
(23%). Rates of informed choice to accept were higher at the hospital
conducting tests as part of a routine visit than as a separate visit (41% vs
21%).
Conclusion: Screening conducted as part of a routine visit is associated with
higher rates of informed choice, than if it is conducted at a test-specific
separate visit. An experimental test of this observation is underway.

Ospedale, Padova, ITALY.
The aim of the study was to evaluate the psyco-social impact of the
identification of a foetal chromosomal anomaly on couples who underwent
prenatal diagnosis in the years 1996-2000 and were referred for genetic
counselling to our service.
Inclusion criteria were the identification of a chromosomal anomaly that may
have no phenotypic consequences or only mild ones: variant, mosaicism (I-II
level), balanced familial inversion or translocation, familial or denovo extra
structurally abnormal chromosomes (ESACs) and sex chromosomes aneuploidies.
Exclusion criteria were: presence of a malformation detected by ultrasound, or
autosomal aneuploidy, or unbalanced chromosomal anomaly.
Both parents have been interviewed and asked to fill in a questionnaire,
consisting in two parts (general information, scale for the assesment of
anxiety).
RESULTS
A total of 36 couples were included in the study and 30 agreed to participate:
13 sex-chromosome anomaly, 11 mosaiscisms, 4 translocations, 1 ESACs, 1
variant. Only 10/30 had a formal counselling by the obstetrician before the
prenatal diagnosis.
2 couples (1 mosaicism II level, 1 45,X/46,XX) underwent an induced abortion,
16 of the 28 remaining couples who decided to continue the pregnancy, did it
after the genetic counselling. There was no differences in the level of
anxiety between the 12 couples who have decided to continue the pregnancy
before the genetic counselling and the others 16.
CONCLUSION
Couples undergoing prenatal karyotiping should be counselled before performing
the tests.
The genetic counselling has an important role in informing parents and in
making the decision to continue the pregnancy.

Interruption of a pregnancy (TOP) after prenatal diagnosis is a challenging
issue on genetic counselling. The need of psychological intervention to
facilitate the adjustment process is well described in literature; however,
few specific empirical data on the decision process and coping with loss of a
wanted pregnancy are available.
Our work focuses in those issues using two different theoretical approaches:
the Ottawa decision support framework and coping with critical life-events,
including cognitive-narrative perspectives on loss.
Our main objectives are: a) to define the weight of difficult adjustment
factors: clinical and social data, coping responses, decision-making
determinants and woman's metaphors for the event; b) to check which coping
strategies are effective preventing anxiety and depression; and c) to define a
program of psychological intervention.
Our protocol includes 4 sessions, with evaluation at 15 days and 6 months
after TOP. At the first post-TOP evaluation, a structured interview is used,
covering social-demographic data, decision determinants (perception of the
decision, perception of significant others, resources available for the
decision-making process) and specific loss issues (social support, knowledge
about the process, grief thoughts and metaphor for the episode), Moos Coping
Responses Inventory, Beck Depression Inventory (BDI), Zung Anxiety Scale (SAS)
and Generic Decisional Conflict Scale. At the 6th month evaluation, a
structured interview, with BDI and SAS, is used.
We discuss the guidelines for the assessment and intervention on this critical
life-event, focusing data on the importance of decision support, the coping
process, emotional and cognitive intentional attribution of the experience and
its metaphor.

Feticide and late termination of pregnancy: impact on parents and health
professionals
H. E. Statham 1, W. Solomou 1, J. M. Green 2;
1Centre for Family Research, University of Cambridge, UNITED KINGDOM,
2Mother and Infant Researach Unit, University of Leeds, UNITED
KINGDOM.
In some countries, legislation permits termination of pregnancy after the
diagnosis of fetal abnormality at gestations beyond fetal viability. Prior to
such a late termination, it is necessary to ensure that the baby is dead prior
to the induction of labour. In the United Kingdom this procedure, feticide, is
usually carried out in specialist fetal medicine units. There are no published
data concerning how parents react to this procedure nor how it impacts on
those health professionals carrying it out.
This paper will use questionnaire and interview data collected from
twenty-eight women and their partners, whose pregnancies were terminated with
the use of feticide after the late diagnosis of a fetal abnormality. We will
describe the impact of this procedure for both men and women, compared with
parents undergoing termination for abnormality at earlier gestations without
the use of feticide. Attitudes to and experiences of the procedure varied
among parents. Overall, no relationship was found between undergoing feticide
or not and maternal emotional well being although a year after a termination,
there was evidence of higher paternal grief in those men whose partner had
undergone a feticide.
We will also describe the findings from interviews with health professionals
(both doctors and midwives) in fetal medicine units, which explored: their
attitudes to the legal framework for abortion in the UK; the policies and
practices that have evolved within the legal framework and Royal College
guidelines; and the impact of this procedure on them as practitioners.

Profiles and motives of couples choosing PGD

Introduction.
The Academic Hospital in Maastricht is the only centre in the Netherlands that
provides Pre-implantation Genetic Diagnosis (PGD). Between 80-100 couples are
referred each year. This gave us the opportunity to investigate the
characteristics and motives of the couples seeking PGD counseling.
The main question was:
Which couples opt for PGD and which factors might influence the course of
treatment?
Method.
As part of the intake a Clinical Geneticist provides information about PGD.
After that a Psychologist interviews the couple. A descriptive analysis of the
first 50 interviews has been performed.
Results.
The presentation mainly deals with the first part of the question i.e. which
couples opt for PGD. Roughly 40% of the genetic disorders that lead to the
wish for PGD are autosomal dominant late onset disorders, another 45% are
X-linked or autosomal recessive disorders and 15% of the cases have frequent
early abortions due to translocations. Couples generally underestimate the
impact of the disorder on quality of life. Women and men mention similar
motives for parenthood. Couples feel medium to high time pressure in 60% of
the cases. Alternative options to get a healthy child are considered in 50% of
the cases but 70% express a strong preference for PGD. Sufficient social
support is reported by 80% of the couples and only 10% does not want to
discuss their problems with others. After the initial interview, 60% wants to
continue, 10% declines to go on and 30% wants to reconsider their options.
