Rumination decreases parental problem-solving effectiveness in dysphoric postnatal mothers

Abstract

BackgroundPostnatal depression is associated with poorer parenting quality, but there are few studies examining maternal-specific cognitive processes that may impact on parenting quality. In this study, we examined the impact of rumination on parental problem-solving effectiveness in dysphoric and non-dysphoric postnatal mothers. MethodsFifty-nine mothers with a infant aged 12 months and under, 20 of whom had a Beck Depression Score II (BDI-II) score ≥ 14, and 39 who scored less than 14 on the BDI-II were randomly assigned to either a rumination or distraction condition. Problem-solving effectiveness was assessed post-induction with the “Postnatal Parental Problem-Solving Task” (PPST), which was adapted from the Means Ends Problem-solving task. Parental problem-solving confidence was also assessed. ResultsDysphoric ruminating mothers exhibited poorer problem-solving effectiveness and poorer confidence regarding their problem-solving compared to dysphoric distracting, non-dysphoric distracting, and non-dysphoric ruminating mothers. LimitationsA self-report measure of depressed mood was used. ConclusionsRumination may be a key mechanism associated with both depressive mood and maternal parenting quality during the postnatal period.
