Life stress, social support, coping and depressive symptoms: a comparison between the general population and family caregivers

Major depression is one of the four most prevalent psychiatric diseases in Taiwan. Furthermore, a study showed that 45 per cent of the family caregivers of persons with persistent psychiatric disability were at risk of depression. The present study aimed at examining if caregivers experienced more depressive symptoms than the general population while controlling for other variables (direct effect), and if the constellation of correlates of depressive symptoms was different between the general population and caregivers (interaction effect). Data from 1979 subjects were gathered in a national survey, using stratified random sampling. The results revealed that the caregivers experienced significantly more depressive symptoms than the general population. However, the effect disappeared when other variables were taken into account. Life stress appeared to be more important than coping and social support. The other two common correlates of depressive symptoms were age and being unmarried. Relational stress mattered especially for caregivers. Lastly, social support variables were significant only for the general population; satisfaction with support could buffer the negative effect of survival stress on depressive symptoms.
