Suicidal Ideation and Comorbid Disorders in Adolescents and Young Adults Diagnosed with Asperger's Syndrome: A Population at Risk

ABSTRACT

The purpose of this study was to examine the level of suicidal ideation and comorbid disorders (major depressive disorder, generalized anxiety disorder) among adolescents and young adults with diagnosed Asperger's syndrome (AS). A cross-sectional study using a self-administrated mail questionnaire and a Web-based questionnaire were used. Two samples were selected for this study. The first sample used snowball sampling, starting with parents of adolescents and young adults with diagnosed AS who participated in a qualitative study conducted in 2002. The second sample consisted of a volunteer sample of parents who visited Web sites for parents and individuals with diagnosed autism spectrum disorder. The sample included 10 adolescents and young adults with diagnosed AS. Fifty percent of the sample had a clinically significant level of suicidal ideation, 20% met criteria for a diagnosis of major depressive disorder, and 30% met criteria for generalized anxiety disorder.
