Conversion and Validation of the Teen-Addiction Severity Index (T-ASI) for Internet and Automated-Telephone Self-Report Administration.

This study converted the Teen-Addiction Severity Index (T-ASI) into self-report formats using Internet (Net) and interactive voice response (IVR) automated-telephone technologies. Reliability and convergent validity were assessed among 95 inpatient adolescent participants. Current functioning scores obtained by clinician interview correlated well with self-report Net (mean r=.74, SD=.14) and IVR (mean r=.72, SD=.16). Lifetime history items obtained by clinicians were consistent with self-report Net (mean r=.60, SD=.32; mean kappa=.67, SD=.24) and IVR formats (mean r=.60, SD=.30; mean kappa=.64, SD=.26). Participants rated "ease of use" as being high for both Net and IVR formats. These findings suggest that automated T-ASI administration is a valid and potentially less expensive alternative to clinician-administered T-ASI interviews.
