情感平衡在长寿老人健康状况与生活满意度之间的中介效应:结构方程模型的应用

Objective To explore the mediating effect of affect balance in the relationship between health condition and life satisfaction in long-lived elders. Methods Overall 439 long-lived individuals (aged 95+ years) from the Rugao longevity cohort were included in the study. Health condition consisted of self-rated health and objective health (measured by disease severity). Life satisfaction and affect balance were measured by Life Satisfaction Index A (LSIA) Scale and Affect Balance Scale (ABS) respectively. Spearman rank correlation and structure equation modeling were used for data analyses.Results The correlations between objective health, self-rated health, affect balance and life satisfaction were all significant (all P<0.05). Objective health and self-rated health had insignificant direct effects on life satisfaction (β=0.02, P=0.791; β=0.16, P=0.153). Objective health and self-rated health showed significant indirect effects on life satisfaction through the mediating effect of affect balance (β=-0.14, P<0.05; β=0.45, P<0.001).Conclusions Affect balance is a mediating variable linking health condition to life satisfaction in long-lived elders.
