The study was designed to measure the effectiveness of a drug counselling program to achieve behavioral, attitudinal and informational change of the participants. Significant changes were found in their responses to the knowledge inventories on medical and legal aspects of drug abuse and on the behavioral dimensions of increased listening skills and ability to critically analyse performance of counsellors. No significant change was found in evaluating the counsellor's overall performance to offer affective responses. Subjects were highly cognitive prior to training, and remained so in their responses after completion of the program. Adoption of a validation model is suggested, which would provide a continuous feedback to the program developed.
