Commentary: the multifaceted nature of maternal depression as a risk factor for child psychopathology--reflections on Sellers et al. (2014).

While much has been learned about depression in mothers as a risk for the development of psychopathology in offspring, many questions about how the risk is transmitted remain unanswered. Moreover, maternal depression is too often considered to be a unitary construct, ignoring the likely diversity among mothers with depression, which could play essential roles in understanding not only mechanisms of risk but also moderators of risk, i.e. for whom the association between maternal depression and adverse offspring outcomes may be stronger. Sellers et al. address both mechanisms and moderators, thereby contributing to the understanding of risk to offspring of depressed mothers in these two important ways. There is much to learn from this work, on many levels and for different audiences, including both researchers and practitioners. A key take-home message of this study for all readers is that understanding the role of maternal depression in associations with child psychopathology requires a nuanced view of the nature of risk to children from depression in mothers. The often co-occurring disorders and highly correlated additional aspects of the context in which depression occurs play important roles in the development of psychopathology in the offspring of depressed mothers.
