Validation of a measure for adolescent self-report of attention deficit disorder symptoms.

The internal consistency, criterion-related, and concurrent validity of the ADD/H Adolescent Self-Report Scale was evaluated using 150 adolescent males ages 12 to 17 years; 103 cases were diagnosed with attention-deficit hyperactivity disorder (ADHD) and 47 with no known psychiatric condition. Participants completed the ADD/H Adolescent Self-Report Scale; their mothers completed the Conners Parent Questionnaire and Child Behavior Checklist. For the ADD/H Adolescent Self-Report Scale, Cronbach's alpha coefficients ranged from .81 to .91. Criterion-related validity was established when it was found that ADHD adolescents reported significantly more problems than controls on all 11 scales. Concurrent validity was established through the finding of moderately strong correlations between comparable scales of the adolescent and parent measures.
