The Adolescent Behavior Checklist: normative data and sensitivity and specificity of a screening tool for diagnosable...

Individuals with mental retardation are almost twice as likely to demonstrate severe behavioral problems or symptoms of mental illness as are nonmentally retarded individuals. At present, however, the ability to diagnose a mental disorder in an individual with mental retardation is difficult, and instruments are needed to help facilitate this process. The Adolescent Behavior Checklist was developed with this purpose in mind. This self-report scale is used to assess the likelihood that an adolescent with mild mental retardation or borderline intelligence has a diagnosable mental illness. The 86-item yes/no self-report scale renders scores on eight subscales derived from DSM III-R. The checklist has been found to have good criterion and congruent validity and good test-retest reliability. Data regarding interrater reliability and the sensitivity and specificity of the scale are presented, as are implications for future research.
