Multiple endocrine neoplasia type 2 (MEN 2) is an autosomal dominant early-
onset cancer disorder. In the Netherlands presymptomatic genetic testing fo
r MEN 2 is offered to testees from the age of five years. We report on adul
ts requesting testing for themselves (n=90) and on parents who want an at-r
isk child to be tested (n=26). Sociodemographic, personality, and attitude
characteristics, and levels of psychological distress, were determined for
applicants and their partners in the predisclosure phase of testing. These
participants showed only mildly increased levels of psychological distress,
defined as heightened scores on measures of general and test-related anxie
ty, and of psychological complaints. Compared with a normal population, hig
h levels of anxiety and health complaints were found in applicants who were
younger than 25 years and single, and in persons who generally tended to r
eact to distressful situations with anxiety or depression. These characteri
stics were particularly evident in young applicants (<25 years). Our study
shows that people who feel ambivalent towards DNA. testing and who are more
vulnerable to psychological distress are more likely to agree to participa
te in the test as part of a collective application by members of a heredita
ry cancer family. (C) 2000 Wiley-Liss, Inc.
