Are higher levels of work–family enrichment a consequence or manifestation of certain personality traits and individuals’ psychological functioning? Using random intercept cross-lagged panel models, we examined the hypothesized stability of work-to-family enrichment (WFE) and family-to-work enrichment (FWE) over two 10-year intervals, and the extent to which the within-person changes of WFE and FWE are associated with personality traits, psychological well-being, and possible gender differences. In this 20-year, longitudinal data analysis of employed adults (N = 535), results indicated the robust nature of the stability of WFE and FWE. Our results suggest that personality traits are not associated with within-person change for either WFE or FWE, but psychological well-being is associated with within-person change. Theoretically and conceptually, our findings provide strong evidence that work–family enrichment is not simply an “optimistic worldview” created by personality and well-being. The within-person results lend strong evidence that interventions that improve psychological well-being will also enhance work–family enrichment.

更高水平的工作-家庭充实是某些人格特征和个人心理功能的结果或表现吗？使用随机截距交叉滞后面板模型，我们检查了工作对家庭丰富 (WFE) 和家庭对工作丰富 (FWE) 在两个 10 年间隔内的假设稳定性，以及个人内部WFE 和 FWE 的变化与人格特征、心理健康和可能的性别差异有关。在这 20 年的就业成年人纵向数据分析中（N= 535)，结果表明 WFE 和 FWE 稳定性的稳健性。我们的研究结果表明，无论是 WFE 还是 FWE，人格特质都与人内变化无关，但心理健康与人内变化有关。从理论上和概念上讲，我们的研究结果提供了强有力的证据，证明工作与家庭的充实不仅仅是由个性和幸福感创造的“乐观世界观”。个人内部结果提供了强有力的证据，表明改善心理健康的干预措施也将增强工作家庭的丰富性。
