The Recognition of Attention Deficit Hyperactivity Disorder, Autism Spectrum Disorder and Conduct Disorder in Adolescents and Adults—Assessing Differences in Mental Health Literacy

This was a Mental Health Literacy (MHL) study looking at three disorders, part of a systematic research programme on MHL using vignette methodology to examine lay people’s knowledge and recognition. The study compared the recognition of the disorders in children and adults. In all 485 participants, aged 18–69 years, read three vignettes describing a person with Attention Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), and Conduct Disorder (CD). Vignette characters were described as either a child (aged 8yrs) or adult (aged 28 yrs). Participants attempted to label the disorder and then rated perceived seriousness and likelihood of disorder. Results from a 2 (sex) × 3 (disorder) way analysis of variance showed that CD was significantly perceived as the most serious disorder. ADHD was significantly considered more likely to be a disorder in adults yet recognised more in children. Younger participants correctly recognised ADHD, yet gave lower seriousness ratings. ASD was considered more serious in children. Women and highly educated individuals perceived ASD more seriously and recognised it more. Parents incorrectly identified CD but considered all disorders more seriously than non-parents. Clinical behaviours are more likely to be perceived as a disorder if they occur in adults, rather than children.
