Studies revealed a positive association between alcohol consumption and disinhibitory personality traits, as assessed by the KSP (Karolinska Scales of Personality). These traits include sensation seeking, characterized as a desire to avoid monotony and seek change and action, as well as impulsivity, defined as acting spontaneously without planning. Further research also found a connection between higher levels of discounting in a hypothetical money-reward task and alcohol-related problems, such as experiencing blackout episodes, among a sample of college students who engage in social drinking.
