Abstract
Background/Objectives: Negative emotional inertia describes the extent to which a prior emotional state can predict the subsequent one, and it is considered a significant indicator of psychological maladjustment that has several negative consequences in the workplace. The current study tested a theoretical model in which the inertia of negative emotions is moderated by regulatory emotional self-efficacy beliefs (RESE) in managing negative affects across workers of different ages. Specifically, we hypothesized that RESE moderates the relation between negative emotions at consecutive time points, reducing their persistence, and that age would influence this relation, with older workers relying less on this resource than younger ones. Methods: Participants were 221 workers (57.8% females) exposed to social work stressors who reported their affectivity every evening for 31 consecutive days. We analyzed the data using dynamic structural equation models (DSEM), which enable examining within-person time series trends while estimating individual differences therein. Results/Conclusions: In line with our predictions, results suggest that emotional self-efficacy is a key personal resource that might be able to buffer individuals from emotional stasis, a resource primarily useful for younger workers who rely less on actual emotional regulation expertise than older adults.
