To study the longitudinal relationship between loneliness and quality of life (QoL) in adults to identify key mechanisms to better design future psychosocial interventions. 13,222 participants from three consecutive waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE), aged 65 or older, 56.3% women. They were analyzed using cross-lagged panel model (CLPM), random intercept cross-lagged panel model (RI-CLPM), and multi-group models disaggregated by gender. The RI-CLPM provided a better fit than the CLPM. Both models showed the stability of QoL and loneliness. All autoregressive paths were significant, and a negative association between concurrent QoL and loneliness was observed across all waves. The CLPM supported a reciprocal relationship, while the RI-CLPM only confirmed the effects of loneliness on QoL. Women reported higher levels of loneliness and poorer QoL, but no gender differences were identified in the longitudinal association. Addressing loneliness in early stages could be a better preventive measure to promote quality of life in both genders.
研究成年人孤独感和生活质量（QoL）之间的纵向关系，以确定关键机制，从而更好地设计未来的社会心理干预措施。 共有来自欧洲健康、老龄化和退休调查（SHARE）的三个连续波次的 13222 名 65 岁及以上的参与者，其中 56.3%为女性。采用交叉滞后面板模型（CLPM）、随机截距交叉滞后面板模型（RI-CLPM）和按性别分组的多组模型进行分析。RI-CLPM 比 CLPM 提供了更好的拟合度。两个模型均显示 QoL 和孤独感的稳定性。所有自回归路径均具有统计学意义，且在所有波次中均观察到 QoL 和孤独感之间呈负相关。CLPM 支持互惠关系，而 RI-CLPM 仅确认了孤独感对 QoL 的影响。女性报告的孤独感水平更高，生活质量更差，但在纵向关联中未发现性别差异。在早期阶段解决孤独感可能是促进两性生活质量的更好预防措施。
