The analysis also focused on the importance of the empirical analysis of the relationship between the severity and duration of trauma and the level of PTSD symptoms. The review also explored the usefulness of using a multiple-trauma perspective in understanding the impact of stressful life events across the life span. Findings indicated that the PTSD prevalence rate is 40-50 percent for help-seeking sexually abused children. Firm conclusions regarding the prevalence of PTSD in adults molested as children are not possible due to limitations in research design. Existing research also suggests a particularly high rate of childhood physical abuse in survivors of childhood sexual abuse. However, future studies of PTSD in childhood sexual abuse, childhood physical abuse, and dual abuse need to use standard definitions and measures. 74 references
