Dyadic Reports Using the Parental Support after Child Sexual Abuse Measure: Psychometrics and Associations with Post-Traumatic Stress Disorder Symptoms.

This study assessed the psychometric properties of a new measure, the Parental Support after Child Sexual Abuse (PSCSA) survey, and tested the association between parents' and children's parental support reports and children's post-traumatic stress disorder (PTSD) symptoms. A total of 99 Icelandic children (86.5% girls, 6-18 years old, = 13.9 years) starting therapy for child sexual abuse (CSA) and 98 non-offending parents (90.6% mothers, 23-58 years old, = 41.2 years) participated in the study. Participants completed questionnaires on parental support (PSCSA) and children's PTSD symptom severity (University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition). A total of 18 items were considered for the PSCSA parent version and nine for the PSCSA child version. Five reliable factors emerged for the parent version (Emotional support, Instrumental support, Self-blame, Child blame and Disbelief) using 16 items and one factor (combined Emotional and instrumental support) emerged for the child's version using eight items. On average, ratings for both Emotional and Instrumental support were higher for parents than their children. Emotional support reported by both parents and children was negatively associated with PTSD symptom severity. The PSCSA survey is a promising dyadic measure for future research and clinical use in children's advocacy centres.
