Happy Work, Happy Life? A Replication and Comparison of the Longitudinal Effects Between Job and Life Satisfaction Using Continuous Time Meta-Analysis

Abstract

Capturing the evolving journey of workers' well-being, our research unveils how the intertwined paths of job and life satisfaction shift and shape each other over time. We contribute to the field's understanding of the dynamic interplay between job and life satisfaction by exploring the time-bound nature of satisfaction, teasing apart the between- and within-person effects, and uncovering the relative strengths of these effects. Our findings (k = 28; N = 161 412) suggest that (1) job and life satisfaction are related to one another over time, (2) life satisfaction has a stronger effect (+32%) on future job satisfaction than the converse, (3) these effects peak around 17.2 months (between-person effects), and (4) effects peak at shorter intervals of 8.2 months when accounting for unobserved heterogeneity (within-person effects). In the latter case, the differences between the two effects were still significant, but the dominance of life satisfaction shrank from 32% to 8%. This investigation not only bridges critical gaps but also sets a new precedent for future research on the temporal dynamics of well-being, promising to transform theoretical perspectives and practical approaches alike.
