Onset of depression was associated with an increase of 2.3 (95% confidence interval, 0.2-4.4) psychologically aggressive acts in an average 12-month period, but was not statistically significantly associated with change in physical assault or neglect.Conclusion  Depression is positively associated with maternal perpetration of psychological aggression in high-risk families.
