Psychometric Properties of the Vanderbilt ADHD Diagnostic Rating Scale Completed by Juvenile Corrections Staff.
Objective:This research tests the psychometric performance of the Vanderbilt ADHD Diagnostic Teacher Rating Scale (VADTRS) completed by juvenile corrections (JC) staff.Method:With institutional review board (IRB) approval and appropriate consents/assents, data were collected from case managers (n= 18), teachers (n= 9), youth (n= 261), and an administrative database. Separate psychometric analyses were conducted for case managers and teachers.Results:For both respondent groups, 2-week retest reliability and internal consistency were high for all four VADTRS subscales, and confirmatory factor analysis suggested fit with previously reported VADTRS subscale structure. Significant correlations of VADTRS with respective Revised Behavior Problem Checklist subscale scores indicated good concurrent validity. Discriminative validity was strong for ADHD, but not for conduct subscales. Interrater agreement was poor, similar as reported in other settings.Conclusion:Acceptable VADTRS psychometric performance among two JC staff groups supports guideline-consistent practice of obtaining standardized rating scale information from JC staff to enhance the quality of ADHD treatment.
