Effects of Educational Intervention on Health-Promoting Lifestyle and Health-Related Life quality of Methamphetamine Users and Their Families: a Randomized Clinical Trial

Family-centered empowerment of drug and stimulant users is an effective program for a better response to treatment, prevention of treatment adverse effects, and promotion quality of life (QoL) and lifestyle in the process of discontinuing drug abuse.. This study aimed to determine the effects of educational intervention, based on family-centered empowerment and Pender''s health promotion models, on health-promoting lifestyle and health-related QoL among methamphetamine users and their families..Patients and In a randomized clinical trial, methamphetamine users, who were admitted to Tehran University of Medical Sciences Substance Abuse Treatment Centers, were randomly allocated to three groups: a group for training of methamphetamine users who were in recovery phase (intervention group 1;95 subjects);a group for training of a family member of methamphetamine users who were in recovery phase (intervention group 2; 95 subjects); and a control group (95 subjects). A demographic checklist and a standard questionnaire covering health-promoting lifestyle, health-related QoL, self-efficacy, perceived affect, perceived social support, and perceived barriers dimensions were used to gather required data. Independent-samples t test, paired-samples t-test, and ANCOVA were used to analyze the data.. Analysis of covariance showed that after adjusting for effects of pretest scores, the difference between mean post-test scores of health-promoting lifestyle scale, health-related QoL scale, and all constructs of Pender''s health promotion model (self-efficacy, perceived affect, perceived social support, and perceived barriers) in the intervention group 1 and control group were significant (P< 0.0001). In addition, changes in mean scores of lifestyle scale (42.4 ± 13.6), QoL scale (29.1 ± 14.2), self-efficacy (16.1 ± 2.6), perceived affect (16.1 ± 8), social support (35.4 ± 12.4), and barriers (17.2 ± 15.8) before and after intervention were significant in the intervention group 2 (P < 0.0001).. Application of family-centered empowerment model among methamphetamine users and their families is practically feasible and can result in enhancement and improvement of their QoL, lifestyle, and health promotion model constructs..
