The effectiveness of substance abuse treatment: Development of a brief questionnaire

Abstract

Background: Practitioners need brief instruments to monitor outcomes in both treatment of drugs and alcohol addiction because they are useful to guide decision making in a short time. Objectives: This study aims to develop a brief questionnaire, based on Client Evaluation of Self and Treatment, to evaluate the treatment effectiveness in drug and alcohol addiction treatment settings. Methods: A cross-sectional study using a convenience sample (N = 608) recruited from Division for Intervention on Addictive Behaviours and Dependencies (DICAD-ARS North).

It also revealed a high internal consistency (α =.82). It was found a significant negative correlation (r =-.52, p
