Does Maternal Support Mediate or Moderate the Relationship between Sexual Abuse Severity and Children’s PTSD Symptoms?

Abstract

ABSTRACTMaternal support and abuse severity are often considered to be vital factors in predicting children’s functioning following childhood sexual abuse (CSA); however, much of the prior research has examined support and abuse severity as main effects, without consideration of how these factors may interrelate to predict children’s post-CSA functioning. Further, even though mediators and moderators are conceptually distinct, maternal support has been theorized to be both a mediator and a moderator of symptoms, and it is unclear if support acts as either among sexually abused children. The aim of the present study was to investigate whether caregiver-reported maternal support mediates or moderates the relationships between sexual abuse severity and children’s trauma-related symptoms. The study included 235 treatment-seeking children ages 3–16 (M = 8.85, SD = 3.77) and their non-offending mothers. Contrary to expectations, caregiver-rated maternal support did not mediate nor moderate the relationship between abuse severity and children’s symptoms (range r2 =.002 –.03). Caregiver-rated maternal support may play a small role in mitigating sexually abused children’s trauma symptoms. Irrespective of abuse severity, children with less supportive mothers may not be at heightened risk for experiencing higher levels of trauma-related difficulties.
