Introduction: Women are more susceptible to and are developing both alcohol addiction and problems related to alcohol consumption. The age of alcohol consumption debut correlates with risk factors, many studies confirming that the average age of alcohol consumption debut has decreased especially among women. Objectives: Testing and validating a structural model for a series of psychological variables that would explain the quantity of consumed alcohol and the number of relapses among both women and men diagnosed with alcohol abuse or addiction; comparative analysis of the group of women vs. the group of men as to the invariance of the structure of latent media of the causal model; revealing the implications this model has for the prevention and clinical intervention for rehabilitation. Material and Methods: A sample of 358 persons was involved in the research, all of them hospitalized in psychiatry care units no. 9 and 17 at Dr. “Alexandru Obregia” Hospital. Two categories of predictor variables were included (socio-demographic variables and psychological traits of personality). The dependent variables in this study were represented by the quantity of alcohol consumed and the number of registered relapses. A type of self-report questionnaire has been elaborated.
