Personality Factors and the Short-Term Variability in Subjective Well-Being

The present study used a sample of 60 college students and an intensive longitudinal approach to investigate the variability in subjective well-being (SWB). At the beginning of the semester students provided information related to their personalities, while throughout the semester they provided SWB data on a weekly basis. Considerable between-student and within-student variability in SWB was found. Multiple regression analyses revealed that personality-based models were useful in explaining the variability in SWB. Conscientiousness and the Chance component of locus of control were found to be statistically significant independent personality predictors of variability in SWB. Specifically, students high in conscientiousness and high in external locus of control experienced more variability in SWB over the study period.
