Examining the association between psychological wellbeing with daily and intra-individual variation in subjective wellbeing

A number of studies identify distinct dimensions of psychological and subjective wellbeing. However, few investigations have examined how these distinctive wellbeing dimensions may be related over time. The present study aimed to contribute to this growing body of research by adopting a measurement burst design to examine the association between psychological functioning with daily and intra-individual variation in affect over a 14-day period, controlling for personality. Participants (N = 45) comprised a sample of Australian adults from Canberra, Australia who were observed on up to 14 days over a 2-week period (Mobs = 10.9 (SD = 3.1)). Maximum Likelihood (ML) estimates from a multi-level structural equation model identified psychological functioning as only weakly associated with daily positive affect, and unrelated to daily levels of negative affect and intra-individual variation in both affect domains when adjusting for demographic, personality and daily stressors. Positive and negative daily, events were most strongly associated with positive and negative feelings, respectively. Post-hoc analysis within a Bayesian context confirmed our ML results whilst a Monte Carlo simulation identified sufficient statistical power of significant parameters. Overall, evidence for an association between psychological functioning and daily affect was not identified. (C) 2015 Elsevier Ltd. All rights reserved.
