Abstract
Attributional sytle, self-control, and assertiveness as predictors of drug abuse. This study examines chronicity of addiction and quantity of consumption for several substances as well as self-report on variables such as self-control, self-efficacy, assertiveness and attributional style. The aim was to discover which variables predict severity in drug abuse. It was found that, in general, self-control and assertiveness may predict both chronicity and quantity of cocaine and heroin intake, attributional style for success explains to a certain extent the variability in the chronicity of alcohol, cocaine and heroin consumption, while age seems to have a bearing on predicting chronicity in alcohol and heroin abuse.
