Abstract:
Understanding the predictors of adolescent substance use is important
because it is a recognized health risk due to its debilitating effect in many areas of a
persons life. This predictive correlation study examined adolescent substance use and
its influencing factors including peer drug use, family drug use and misbehaviors,
perceived substance refusal self-efficacy, peer connectedness, school commitment and
impulsivity.Data was collected from 420 students studying in grade 9-12, in one of the
higher secondary schools in Thimphu, Bhutan. The sample was selected through a
multi-stage random sampling. Demographic questionnaire, community that care youth
survey, drug taking confidence questionnaire, positive peer influence questionnaire
and Barratt impulsive scale were used to collect data. Descriptive statistics and
standard multiple regression were used to analyze adolescent substance use and its
predicting factors.
Mean score of adolescent substance use was 24.40 (SD = 8.40), with tobacco,
alcohol and cigarette smoking being the most commonly used drug. Peer drug use,
family drug use and misbehaviors, perceived substance refusal self-efficacy, school
commitment, peer connectedness and impulsivity accounted for 66 % of the variance
in substance use (R
2
= .66, F6, 413 = 131.74, p = .000). Peer drug use was the strongest
predictor (β =0.50, p < 01) and impulsivity was not a good predictor of substance use (β
=.01, p > 05).
The findings of this study shed additional light on adolescent substance use
and its influencing factors. In preventing substance use, peer drug use, perceived
substance use refusal self-efficacy, family drug use and misbehaviors, peer
connectedness and school commitment should be considered.
