The purpose of the present study was to examine the prevalence of depressive symptoms on the Center for Epidemiologic Studies Depression Scale (CES-D) and the effect of life stressors or social support on depressive symptoms in 303 elderly people receiving social services at home. We conducted a questionnaire survey six times with a 1-month interval. In the initial wave of questionnaires, 92 (31%) scored 16 points or above on the CES-D, indicative of a risk for depression. Before life stressors, subjects with low-level support showed significantly more severe depressive symptoms than those with high-level support. Subjects with low-level support were significantly more depressive after life stressors than they had been before, whereas those with middle- and high-level support showed no such difference. The former and latter results seem to suggest the direct and buffering effects of social support on depressive symptoms, respectively.
本研究的目的是调查303名接受居家社会服务的老年人在流行病学研究中心抑郁量表（CES-D）上抑郁症状的患病率，以及生活压力源或社会支持对抑郁症状的影响。我们每隔1个月进行6次问卷调查。在首轮问卷中，92人（31%）在CES-D上的得分达到或超过16分，表明有抑郁风险。在生活压力源出现之前，低水平支持的受试者比高水平支持的受试者表现出明显更严重的抑郁症状。低水平支持的受试者在生活压力源出现后比之前明显更抑郁，而中高水平支持的受试者则没有这种差异。前一个和后一个结果似乎分别表明了社会支持对抑郁症状的直接影响和缓冲作用。
