The Relationship Between Personality and Subjective Well-Being: Different Association Patterns When Measuring the Affective Component in Frequency and Intensity

The aim was to determine whether the relationship between personality traits and Subjective Well-Being (SWB) differs when the affective component of SWB is measured in terms of frequency or intensity. Extraversion and Neuroticism were expected to show significant but different associations to SWB depending on the dimension of the affective component. Swedish undergraduate students (N = 153) self-reported personality, life satisfaction (LS), and affect measured in both frequency (i.e., how often they feel certain affects) and intensity (i.e., how strongly they feel certain affects). Two types of SWB-scores were constructed by merging LS with affect measured in either frequency or intensity. While Extraversion had a similar effect on both types of SWB, Neuroticism had a significantly stronger effect on SWB when the affective component was measured in frequency. More importantly, the effect of Neuroticism, compared to Extraversion, was stronger on SWB regardless of the dimension of the affective component. These findings suggest that future research should clearly distinguish between intensity and frequency when measuring the affective component of SWB. The distinction is important, not only due to the distinctiveness of the affective dimensions per se, but also due to different association patterns between personality traits and both dimensions.
