Maternal depression is associated with cognitive, emotional, and behavioral problems in offspring, but the substantial heterogeneity of depression precludes a full understanding of these associations. Variation in course of depression, characterized by severity or chronicity, may be related differentially to children's development. The current meta-analytic review examined the relations of these characteristics of maternal depression to children's developmental outcomes. Twenty-nine studies were identified and reviewed; the majority (93%) of studies reported a negative association between some aspect of maternal depression and children's adjustment. Separate meta-analyses revealed significant effect sizes for severity (Fisher's z = -.243) and chronicity (adjusted Fisher's z = -.337) of maternal depression and children's cognitive or behavioral functioning. Findings are synthesized across features of maternal depression; methodological limitations within the empirical literature are discussed; and recommendations for future research are suggested.
