Abstract

Background: Drug abuse is one of the important challenges in the field of mental health and adolescence health promotion. Because of the social and medical cost of drug abuse and its consequences among youth people, it is necessary to intervene effectively. This theoretical based study explained predictability of the Theory of Planned Behaviour (TPB) on drug abuse related behaviours.

Methods: This cross-sectional study was conducted in Hamadan City, western Iran, in 2011 among 650 male high school students, recruited randomly. All data were gathered by using self-report written questionnaires include attitudes, subjective, norms, and intention not to use drugs as theoretical constructs of TPB and drug abuse related behaviours.

Results: According to the logistic regression analysis, attitude and subjective norms were the most influential predictors of intention to drug abuse. There was a significant relationship between drug abuse smoking experience (OR=27.24 95% CI: 10.25, 72.40; P=0.001), having parents of drug users (OR=8.63 95% CI: 3.42, 21.81; P=0.001), and having friends who had experienced drug (OR=11.06 95% CI: 4.24, 28.85; P=0.001).

Conclusion: Drug abuse preventative programs need to apply comprehensive theoretical based efforts for drug abuse preventative manipulations in school settings.  Theory of planned behaviour can be used properly and effectively for planning and implementing drug abuse prevention programs in adolescents.
