The purpose of this study was to examine the relationship between childhood trauma and PTSD. Specific objectives included examining the relationship between PTSD and (a) child sexual abuse (CSA) and child physical abuse (CPA), (b) combined abuse, (c) intensity of abuse, and (d) age of onset of abuse. An urban sample of 174 adults were surveyed using the Stressful Life Events Screening Questionnaire (SLESQ) to assess lifetime exposure to traumatic events and the PTSD Checklist-Civilian version (PCL-C) to assess for PTSD. The results showed that participants who experienced combined abuse were more likely to meet PTSD criteria, a statistically significant finding. Also, it was found that higher frequency of CSA was significantly associated with PTSD. No significant differences were found in the risk for PTSD between individuals who experienced CSA or CPA. Age of onset of abuse was not significantly associated with PTSD. Implications, limitations, and clinical recommendations are discussed.
