To examine both cross-sectional and longitudinal relationships between older adults' perceptions of social cohesion in their community and depressive symptoms and the potential mediating effect of the frequency of going outside one's home/building. Using two waves (T1 and T2) of the National Health and Aging Trend Study ( = 5,326), gender-stratified structural equation models were estimated to determine direct and indirect effects of perceived social cohesion on depressive symptoms. At T1, both perceived cohesion and frequency of going out were directly associated with depressive symptoms; however, perceived cohesion predicted frequency of going out only for women. At T2, only frequency of going out was directly associated with depressive symptoms, although perceived cohesion predicted frequency of going out for both genders. T1 perceived cohesion did not predict T2 depressive symptoms. T1 depressive symptoms were the strongest predictor of T2 depressive symptoms. The findings underscore the importance of enhancing the social environment in promoting mental health in late life through active aging.
为了研究老年人对社区社会凝聚力的认知与抑郁症状之间的横断面和纵向关系，以及走出家门/建筑物的频率的潜在中介作用。利用国家健康与老龄化趋势研究的两波数据（T1和T2）（n = 5326），估计了按性别分层的结构方程模型，以确定感知到的社会凝聚力对抑郁症状的直接和间接影响。在T1时，感知到的凝聚力和外出频率都与抑郁症状直接相关；然而，感知到的凝聚力仅对女性的外出频率有预测作用。在T2时，只有外出频率与抑郁症状直接相关，尽管感知到的凝聚力对男女的外出频率都有预测作用。T1时感知到的凝聚力并不能预测T2时的抑郁症状。T1时的抑郁症状是T2时抑郁症状的最强预测因素。研究结果强调了通过积极老龄化来改善社会环境对促进晚年心理健康的重要性。
