Abstract

The current investigation examined self-reported family history of psychological problems in a large sample of individuals diagnosed with generalized anxiety disorder (GAD) and nonanxious controls. The GAD participants were all individuals receiving cognitive–behavioral therapy as part of two large randomized clinical trials. Family history information was obtained from the Anxiety Disorders Interview Schedule-Revised (ADIS-R; DiNardo & Barlow, 1988). The results indicate that, compared to control participants, individuals with GAD were more likely to have family members with anxiety problems, but not other psychological problems. Possible mechanisms for the familial transmission of GAD are discussed. © 2008 Wiley Periodicals, Inc. J Clin Psychol 64: 1–14, 2008.
