War trauma lingers on: Associations between maternal posttraumatic stress disorder, parent-child interaction, and child development.

Maternal traumatization has been proposed as a risk factor for child development, but the mechanisms involved are poorly understood. This study analyzed the interrelations among maternal posttraumatic stress symptoms, parent-child interaction (emotional availability), and infants' psychosocial functioning and development among 49 asylum-seeker and refugee mothers and their children (18-42 months). Measures included assessment of mothers' trauma and comorbid symptoms (Harvard Trauma Questionnaire: R.F. Mollica et al., 1992; Hopkins Symptom Checklist: L. Derogatis, R. Lipman, K. Rickels, E. Uhlenhuth, & L. Covi, 1974), emotional availability within parent-child interaction (Emotional Availability Scales: Z. Biringen, 2008), and infants' psychosocial functioning (Child Behavior Checklist: T.M. Achenbach & L.A. Rescorla, 2000) and development (Bayley Scales of Infant Development: B.F. van der Meulen, S.A.J. Ruiter, H.C. Spelberg, & M. Smrkovsky, 2000). The results show that higher levels of maternal posttraumatic stress symptoms are associated with a higher level of psychosocial problems of infants, but not with delays in their mental or psychomotor development. The results also show that higher levels of maternal posttraumatic stress symptoms are associated with higher levels of insensitive, unstructuring, or hostile, but not intrusive, parent-child interactions. Infants show lower levels of responsiveness and involvement to their traumatized mothers. Parent-child interaction did not function as a mediator between maternal trauma symptoms and infants' psychosocial functioning. Results are discussed in relation to the dyad's regulation of emotions. Results implicate a need to reestablish attunement between traumatized mothers and their nontraumatized children.
