This study examined maternal oxytocin receptor (OXTR, rs53576) genotype and cortisol secretion as moderators of the relation between maternal childhood maltreatment history and disorganized mother-infant attachment in the Strange Situation Procedure (SSP). A community sample of 314 mother-infant dyads completed the SSP at infant age 17 months. Self-reported maltreatment history more strongly predicted mother-infant attachment disorganization score and disorganized classification for mothers with more plasticity alleles of OXTR (G), relative to mothers with fewer plasticity alleles.

We assessed a community sample of 96 mother-child dyads. At child age 16 months, mothers self-reported maltreatment history, adult attachment, depressive symptoms, and social support, and maternal sensitivity was assessed via 2 hr of direct behavioral observation.

This study investigated the influences of maternal history of care and maternal DRD2, SLC6A3, and OXTR genotypes on maternal cortisol in the context of infant stress. A community sample of 296 mother-infant dyads completed a maternal separation at infant age 17 months.

This study aimed to determine which dimensions of parenting, notably parenting efficacy, positive parenting, inconsistent discipline, and poor supervision, mediate the association between parent lifetime internalizing symptoms and post-PT child emotional and behavioral difficulties. One hundred fourteen parents (82% biological mothers) of children aged 9-12 years received PT at an urban children's mental health clinic.

One hundred fourteen parents of 9-12-year-old children with conduct problems were randomized to Coping Power or individualized treatment at an urban children's mental health clinic. Parents reported their pre- and post-treatment parenting efficacy and parenting satisfaction (Parent Sense of Competence Scale).

Both maternal depressive symptoms and infants' dopamine-related genetic characteristics have been linked to infants' hypothalamic-pituitary-adrenal (HPA) functioning. This study investigated the interactive influence of maternal depressive symptoms and infant DRD2 and SLC6A3 genotypes on infant cortisol reactivity; whether this interaction reflects diathesis-stress or differential susceptibility; and whether this interaction influences the flexibility of the infant cortisol response across challenges known to exert differential effects on infant cortisol reactivity. A community sample of 314 mother-infant dyads participated in toy frustration (age 16 months) and maternal separation (age 17 months) challenges, and salivary cortisol was collected at baseline, +20, and +40min.
