CBT for Child PTSD is Associated with Reductions in Maternal Depression: Evidence for Bidirectional Effects.

Cognitive behavioral therapy techniques are empirically supported for posttraumatic stress disorder (PTSD) in youth, but the role of parents in such treatments is less clear. Theoretically there may be a reciprocal relationship such that as children improve, their parents may feel better, and conversely as parents feel better, psychologically the child may improve or improve at a greater rate. This study tested if there were indirect effects of change in child PTSD symptoms on change in parent depression symptoms, and vice versa, across treatment sessions. The data came from a randomized trial of treatment for PTSD and included youth (N = 47) 7-18 years old (51.1% female; ethnicity was reported as 40.4% White and 40.4% Black, with the remainder reporting Mixed [17%] or other ethnicity [2.1%]) who had been exposed to trauma and experienced significant PTSD symptoms. Maternal depression and child PTSD symptoms were assessed at each session. Maternal perceptions of who changed first were also assessed at posttreatment. Maternal depression significantly decreased over the course of treatment, and maternal depression had an indirect effect on child PTSD symptom change. Evidence for the reciprocal relationship, child symptom change having an indirect effect on parent symptom change, was also found. Age, gender, and treatment condition did not moderate these indirect effects. Findings highlight the potential benefits of child therapy on parents and the reciprocal benefits of improved parent symptoms on the child.
