The mechanisms underlying the negative effect of depression on life satisfaction among the elderly: the roles of ostracism and economic income.

OBJECTIVES

Depression is prevalent among older persons, which seriously threatens their life satisfaction. This study aimed to explore the internal mechanisms by which depression influences life satisfaction among the elderly, as well as the mediating and moderating effects of ostracism and economic income, respectively, in a sample of rural older adults across China.

DESIGN

This was a cross-sectional survey conducted as part of the project "Thousands of People and Hundreds of Villages (2019)."

SETTING

Participants were rural older adults from 31 provincial-level administrative units across China.

PARTICIPANTS

The sample composed of 1,754 participants aged 60 years and over.

MEASUREMENTS

Depression was assessed with the depression subscale of the Depression Anxiety Stress Scales, life satisfaction with the Satisfaction with Life Scale, ostracism with the Ostracism Experience Scale (OES), and economic income and other control variables with related demographic scales. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes ().

RESULTS

Depression negatively predicted life satisfaction among the elderly. Ostracism played a partially mediating role between depression and life satisfaction. Economic income moderated the effect of depression and ostracism on life satisfaction: High economic income weakened the negative effect of depression on life satisfaction and enhanced the negative effect of ostracism on life satisfaction.

CONCLUSION

Improving depressed elderly people's interpersonal relationships and financial support could improve their life satisfaction.
