The problem of increased alcohol consumption is an inexhaustible topic of numerous studies. Because of the awareness of the factors that contribute to alcohol dependency, the aim of the present study was to examine the relationship between temperament, defensive styles, and abuse in childhood with alcohol consumption. The research was conducted online, with 287 participants (128 men and 159 women), aged 18 to 78, taking part. The Temperament Scale was used to measure temperament, the Defense Styles Questionnaire was used to define defensive styles, the Childhood Abuse Questionnaire was used to detect the presence of childhood trauma, and the Alcohol Consumption Scale taken from the AUDIT questionnaire was used to detect the level of alcohol consumption. Hierarchical regression analysis on a sample of men revealed that temperament is not a significant predictor of alcohol consumption, while physical and sexual abuse in childhood significantly contributes to alcohol consumption. Also, it was found that the use of an immature defensive style in men contributes to increased alcohol consumption. By conducting a second hierarchical regression analysis on a sample of women, it was determined that the novelty-seeking temperament dimension contributes to increased alcohol consumption. Neglect and sexual abuse are forms of childhood trauma that contribute to increased alcohol consumption. Regarding defensive styles, it was found that only a mature defensive style in women contributes to alcohol consumption. Overall, childhood trauma has the greatest contribution to alcohol consumption compared to temperament and defensive styles.
