Jingle all the way? Pleasant and energized positive affect show differential longitudinal relationships with life satisfaction and personality

Positive affect (PA) is operationalized differently across studies, leaving open whether distinct conceptualizations relate to subjective wellbeing (SWB) similarly over time. Although mainstream wellbeing theory treats PA and life satisfaction (LS) as components of a latent SWB factor, empirical findings on their causal relations remain inconsistent. This study examined whether pleasant versus energized PA show comparable longitudinal associations with LS using random-intercept cross-lagged panel models across nine waves from two national longitudinal datasets, PAIRFAM (N = 12,520) and LISS (N = 17,532). Both PA types showed consistent bidirectional associations with LS, but relationships were stronger for pleasant PA. Cross-lagged effects and time-specific residual correlations were approximately twice as large compared to energized PA. Pleasant and energized PA also differed in their associations with extraversion and neuroticism. These findings suggest that PA indicator choice affects SWB measure validity, with implications for positive psychology interventions targeting SWB.
