The moderating role of personality in the relationship between chronotype and alcohol consumption

Master thesis | Psychology (MSc)

Previous research found that personality and chronotype both are significant predictors of alcohol consumption. This study examined the personality type neuroticism and the evening chronotype as possible correlates of increased alcohol consumption. Additionally, we aimed to find a moderating effect of eveningness in the relationship between neuroticism and alcohol consumption. The Netherlands Study of Depression and Anxiety (NESDA) included 2,981 participants between the ages of 18 and 65 and a total of more than eight questionnaires, from which we used the Munich Chronotype Questionnaire (MCTQ), Alcohol Use Disorder Identification Test (AUDIT) and Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI). Results showed a significant association between eveningness and alcohol consumption. The predicted moderation effect of eveningness was not found.

Results showed a significant association between eveningness and alcohol consumption. The predicted moderation effect of eveningness was not found. The findings of this study may give a better understanding of possible risk factors for increased alcohol consumption, by verifying the predicted association between eveningness and increased alcohol consumption. Future research may however look further into the working mechanisms of eveningness with respect to the susceptibility of increased alcohol consumption.Show less
