This study assessed the prevalence of a wide range of behavioral and emotional problems in 706 19- to 24-year-olds from the Dutch general population using the Young Adult Self-Report (YASR). The prevalence rates found can be used to make comparisons with data from individuals or other samples. Large or medium (variance > 5.9%) sex effects were found for alcohol use, for the items 'Brags' and 'Swears' (males > females), and for the items 'Cries a lot' and 'Fears' (females > males). With respect to socially desirable items, females more often reported attitudes or behaviors pertaining to helping other people, while males more often reported competitive behaviors or attitudes. For YASR syndromes, higher mean scores for females than males were found for the Withdrawn, Somatic Complaints, and Anxious/Depressed syndromes, while mean scores on the Delinquent Behavior syndrome were higher for males than females. No age effects were found, indicating that normative data were similar across the 19- to 24-year age span. Compared to other problem areas, thought problems and delinquent behavior in males, and social problems and delinquent behavior in females were least likely to be associated with other types of problems. Hence, instruments for the assessment of psychopathology in young adults should include these areas to provide a comprehensive picture of behavioral and emotional problems.
