A comparative study on metacognition and its relation to aggression among addict recovered addict- and non-addicted to drugs subjects

The aim of this study was to compare metacognition and its relationship with aggression among drug addicts, drug-quitting addicts, and non-addicts.
In this causal-comparative and correlational study enrolled 62 drug addicts, 51 individuals in addiction-quitting stage, and 96 no- addicts through convenience sampling. Subjects were investigated by the metacognition questionnaire (MCQ-30) and the Ahvaz Aggression Questionnaire.
Multivariate analysis of variance demonstrated significant differences in the mean scores of drug-quitting addicts and non-addicts in negative beliefs subscale related to uncontrollability and risk (F=3.65, P Our findings suggested that drug addicts tend to have a weaker metacognition as compared to non-addicts. The increase in the intensity of aggression was shown to be related to the increased cognitive dissonance. Such results retain important implications in the prevention and treatment of addiction and aggression.
