Student attitudinal inventory for outcome evaluation of adolescent drug abuse prevention programs.

This study introduces an evaluation instrument entitled the "High-Risk Student Attitudinal Inventory." It can be used for outcome evaluation in assessing the effectiveness of various primary prevention programs aimed at deterring adolescent drug abuse. This instrument has seven attitudinal syndromes that are theoretically based and are empirically related to student drug involvement. Each attitudinal syndrome is composed of ten Likert-type scale items. The mean Cronbach Alpha coefficient of reliability pertaining to the scales is .83. Criterion-related validity of the scales is established through a known-group method. The groups identified are the current drug users and non-drug users.
