Alcohol addiction is one of the most prevalent disorders in the general population. Apart from the fact that treatment of this disorder is aggravated by it's relapsing nature, treatment is further complicated by frequent occurrence of comorbid disorders. Research indicates that comorbidity of alcohol addiction and depression is a fairly frequent phenomenon that affects the course and treatment outcomes of both disorders. Out of numerous factors that potentially contribute to the appearance and maintenance of depressive symptoms, in this thesis, the emphasis is placed on gender and some cognitive predictors, i.e. on cognitive strategies of emotional regulation and self-esteem. Therefore, the aim of this research was to determine the predictive contribution of gender, self-esteem, and cognitive strategies of emotional regulation in explaining the severity of symptoms of depression in people addicted to alcohol. The following instruments were applied to a sample of 72 people addicted to alcohol: General Data Questionnaire, Cognitive Emotion Regulation Questionnaire, Rosenberg Self-Esteem Scale and Beck Depression Inventory. The results of the hierarchical analysis indicate that self-esteem, above gender, is a negative predictor of depression. Other variables in the final model did not prove to be significant predictors of depression in alcohol dependent individuals.
