Psychometrics of a Child Report Measure of Maternal Support following Disclosure of Sexual Abuse.

The study examined a new child report measure of maternal support following child sexual abuse. One hundred and forty-six mother-child dyads presenting for a forensic evaluation completed assessments including standardized measures of adjustment. Child participants also responded to 32 items considered for inclusion in a new measure, the Maternal Support Questionnaire-Child Report (MSQ-CR). Exploratory factor analysis of the Maternal Support Questionnaire-Child Report resulted in a three factor, 20-item solution: Emotional Support (9 items), Skeptical Preoccupation (5 items), and Protection/Retaliation (6 items). Each factor demonstrated adequate internal consistency. Construct and concurrent validity of the new measure were supported in comparison to other trauma-specific measures. The Maternal Support Questionnaire-Child Report demonstrated sound psychometric properties. Future research is needed to determine whether the Maternal Support Questionnaire-Child Report provides a more sensitive approximation of maternal support following disclosure of sexual abuse, relative to measures of global parent-child relations and to contextualize discrepancies between mother and child ratings of maternal support.
