Abstract:
Objective:To investigate the mediating and moderating effects of resilience on frailty and depression in the community-dwelling old adults.Methods:Totally 871 community-dwelling old adults chosen from different communities were investigated by the geriatric depression scale, Tilburg frailty indicator and 10-item Connor-Davidson resilience scale.SPSS 22.0 and AMOS 24.0 were used for data analysis, including descriptive analysis, correlation analysis, structural equation modeling and hierarchical regression analysis.Results:(1)The score of frailty (3.72±2.89)was positively correlated with the score of depression (2.63±2.57, r=0.16-0.58, P<0.01). The score of resilience(28.24±6.80) was negatively correlated with the score of frailty and depression ( r=-0.10~-0.49, both P<0.01), and frailty predicted 35% of the total variation of depression in the elderly.(2)The mediating effect of resilience was significant and the indirect effect was 0.10, accounting for 12.66% of the total variance.(3) Resilience moderated the relationship between frailty and depression ( β=-0.12, t=-4.11, R2=0.41, P<0.001). The frailty of old adults with lower resilience played a stronger predictive role in depression (simple slope=0.50, t=14.73, R2=0.01, P<0.001). Conclusion:There is a close relationship between frailty and depression in the community-dwelling older adults, and resilience plays both mediating and moderating role in the relationship.
