The authors conducted a meta‐analysis of studies on the correlation between parents’ PTSD symptom severity and children's psychological status. An extensive search of the literature yielded 550 studies that were screened for inclusion criteria (i.e., parent assessed for PTSD, child assessed for distress or behavioral problems, associations between parent PTSD and child status examined). Sixty‐two studies were further reviewed, resulting in a final sample of 42 studies. Results yielded a moderate overall effect size r = .35. The authors compared effect sizes for studies where only the parent was exposed to a potentially traumatic event to studies where both parents and children were exposed. A series of moderators related to sample characteristics (sex of parent, type of traumatic event) and study methods (self‐report vs. diagnostic interview, type of child assessment administered) were also evaluated. The only significant moderator was type of trauma; the effect size was larger for studies with parent–child dyads who were both exposed to interpersonal trauma (r = .46) than for combat veterans and their children (r = .27) and civilian parent–child dyads who were both exposed to war (r = .25). Results support the importance of considering the family context of trauma survivors and highlight areas for future research.
