Abstract

Addiction is a physiological and psychological and social disorder that is considered a major health problem in many societies. This disorder is associated with difficulties in the ability of addicted patients to resist and prevent self-destructive and risk situations. This has led to numerous studies that have managed to demonstrate that there is a relationship between the self-efficacy and motivation of these patients aimed at changing addictive habits, even being considered as predictors and/or mediators of the effects of treatment. This article proposes to understand self-efficacy in a broader way (self-agency) that goes beyond the cognitive and behavioural aspects necessary, which also includes an adequate level of self-regulation, commitment and lifestyle changes, all of which are necessary to obtain successful and stable therapeutic results over time.
