2. Posttraumatic Stress Disorder Criteria (DSM-IV-TR, 2000) Psychiatric Disorder, Classified as Anxiety Disorder Criterion A Traumatic Event Or, series of events Directly or indirectly experienced Subjective Response Involve: intense fear, helplessness, or horror Criterion B Reexperiencing Symptom Cluster Intrusive thoughts Distressing dreams Trauma cue distress Criterion C Avoidant Symptom Cluster Avoid trauma-related thoughts, places, feelings Criterion D Hyperarousal Symptom Cluster Insomnia Irritability, anger, hypervigilance

4. Criterion A Traumatic Event Subjective Response Fear, helplessness, or horror Magnitude of subjective response Epidemiological study: PTSD onset depended most on it , not traumatic event (Breslau & Kessler, 2001) Peritraumatic hyperarousal Longitudinal: (elevated HR) to imaginal trauma cues at 1 month and at 3 months was most significant predictor of PTSD onset at 3 months (Elsesser, Sartory, & Tackenberg, 2005) Peritraumatic dissociation Meta-analysis of risk factors: most significant predictor of PTSD, and better predictor than prior events (Ozer, Best, Lipsey, Weiss, 2003) Subjective response CRITICAL to PTSD onset?
