DSM-IV Disorders in Children With Borderline to Moderate Intellectual Disability. II: Child and Family Predictors

To identify child and family factors that predict DSM-IV disorders in children with intellectual disability. In 1997, a total of 968 6- to 18-year-olds were randomly selected from Dutch schools for intellectual disability (response 69.3%). Parents completed the Child Behavior Checklist, Developmental Behavior Checklist, Vineland Screener, and instruments addressing their child's physical health, family functioning, and parental mental health. One year later, parents of 474 children, randomly selected from the 1997 participants (response 86.8%), completed the anxiety, mood, and disruptive disorder modules of the Diagnostic Interview Schedule for Children-IV. Both child and family factors were significantly related to DSM-IV outcome 1 year later. Social incompetence, inadequate daily living skills, child health problems, negative life events, emotional and behavioral problems, and parental mental health problems were the strongest predictors of DSM-IV disorders 1 year later. After correcting for the level of behavioral problems in the previous year, the first four factors proved to be significant risk factors for DSM-IV outcome. These factors can improve the identification of children at risk and point to topics that need attention in diagnostic and intervention procedures.
