The purposes of this study are to develop and empirically test a theoretical model that examines the relationships between a set of predictors and depression among older adults. A biopsychosocial model was tested with 317 community dwelling older adults residing in Chon Buri Province, Thailand. A face-to-face interview was used in a cross-sectional community-based survey. A hypothesized model of depression was tested by using path analysis. It was found that the modified model fitted the data and the predictors accounted for 60% of the variance in depression. Female gender, activities of daily living, loneliness, stressful life events, and emotional-focused coping had a positive direct effect on depression. Social support and problem-focused coping had a negative direct effect on depression. Additionally, perceived stress, stressful life events, loneliness, and income had a negative indirect effect on depression through social support. Female gender, activities of daily living, and perceived stress also had a positive indirect effect on depression through emotional-focused coping. Stressful life events, perceived stress, and income had a negative indirect effect on depression through problem-focused coping. These findings contribute to a better understanding of the variables that predict depression in older adults. Thus, health care providers should consider the effects of these contributing factors on depression in the older adult person and can devise a program to prevent and promote health in older adults alleviating depression.
