Brief Summary

In recent years ketamine abuse becomes prevalent in youth in some Asian countries. Chronic ketamine abuse may lead to uropathology and cognitive impairments. No pharmacological interventions have been identified as effective for treating ketamine abuse or helpful in achieving or maintaining abstinence from ketamine. Cognitive-behavioral treatment is currently an important psychosocial intervention for addictive problems. This study aimed to test whether a brief cognitive-behavioral training program has a positive influence on stage transitions among ketamine abusers.

Detailed Description

409 ketamine abusers were recruited in this study, with 285 ketamine abusers participated in a 6-hour brief cognitive-behavioral intervention and 124 ketamine abusers attended educational lectures on ketamine abuse. A brief cognitive-behavioral intervention was applied to teach ketamine abusers about stimulus control, refusal skills, communication skills, decisional balance, and infectious diseases prevention. Stage of Change and knowledge about ketamine were assessed before and after the intervention.
