Is it me or my child? The association between maternal depression and children's behavior problems in mothers and their children with or without autism.

Bidirectional associations between maternal depression and child behavior problems have been reported in prior research, however, few studies examine these relations across varied family contexts. This study examined parenting stress and child diagnosis of autism spectrum disorder (ASD) as moderators of bidirectional associations between maternal depression and child behavior problems over time. Our sample included 86 mother-child dyads who reported maternal depressive symptoms, child behavior problems, and parenting stress at three time points over more than 1 year. Approximately half were mothers of children with ASD (n = 41) and half were mothers of neurotypical children (n = 45). We tested the bidirectional associations between maternal depressive symptoms and children's behavior problems and the potential moderating role of parental stress or child ASD diagnosis on these bidirectional associations using aggregated, lagged, and linear mixed models. Even after controlling for lagged maternal depressive symptoms, child behavior problems were associated with greater subsequent maternal depression at the between-person level, but not at the within-person level. The converse relation of prior maternal depressive symptoms on subsequent child behavior problems was not significant. Neither parenting stress nor child ASD diagnosis moderated bidirectional associations between maternal depressive symptoms and children's behavior problems. Child behavior predicted maternal depression, but the converse was not true, regardless of parenting stress levels or child's ASD diagnosis. For mothers experiencing elevated parenting stress and those with children with ASD, this may help alleviate elevated feelings of guilt related to their children's behavior problems.
