Determinants of depression severity and duration in canadian adults: The moderating effects of gender and social support

This study examined the effects of 4 subtypes of social support (tangible, affective, positive social interaction, and emotional/informational) and gender on the severity and duration of depressive symptoms within the general adult Canadian population. Data were collected from the Canadian Community Health Survey (CCHS; Statistics Canada, 2002). Upon meeting predetermined criteria, 6,316 participants were included in the study. The findings suggest that, overall, positive social interaction was significantly associated with decreases in depression severity; while emotional/informational support was significantly associated with increases in depression severity. Positive social interaction and emotional/informational support appeared to significantly decrease the duration of depression. Interesting gender differences also emerged among the 4 subtypes of social support. Implications of the findings are discussed.
