4 PTSDA. Traumatic event experienced with fear, helplessness, horror, extreme distressB. Re-experiencing (Intrusion)C. AvoidanceD. HyperarousalE. Symptoms present for 1 month or moreF. Distress social/occupational function
5 Acute Stress Disorder (ASD): Criterion Three dissociative symptomsDerealizationNumbing or detachmentReduced awareness of surroundingsDepersonalizationDissociative amnesia
6 Acute Stress Disorder (ASD): How predictive is it? Prospective studies find that a high proportion of those diagnosed with ASD develop PTSD.However, in terms of people who eventually developed PTSD, about half of those met criteria for ASD.
7 B: Re-experiencing SXS (1) needed Distressing intrusive recollectionsDistressing Dreams of the eventReliving the experience (flashbacks)Distress at exposure to remindersPhysiological reactivity at exposure to trauma reminders
8 C: Avoidance/Numbing SXS (3) needed Avoid thoughts/feelings that remindAvoid activities/situations that remindInability to recall aspects of the traumaDiminished interest in activitiesDetachment/Estrangement from othersRestricted range of affectSense of foreshortened future
9 D: Hyperarousal Symptoms (2) needed Difficulty falling/staying asleepIrritability or outbursts of angerDifficulty concentratingHypervigilanceExaggerated startle

19 PTSD Prevalence in US Adults National Comorbidity Survey NCS-Replication (2005)Large national probability samples (Ns > 5000)Benchmark for prevalence of mental disorders in USLifetime PTSD prevalence = 6.8% (NCS-R)9.7% women3.6% menCurrent PTSD prevalence = 3.6% (NCS-R)5.2% women1.8% men
20 Prevalence Of Trauma And PTSD More Than 60% Experience A Traumatic Event In Their Life More Than 25% Experience Multiple Traumatic EventsKessler et al., 1999
21 Combat Exposure in the NCS Lifetime prevalence of PTSD = 39% among combat veteransMale combat vs. all other male traumaHigher lifetime PTSD prevalenceGreater likelihood of delayed onsetGreater likelihood of unresolved symptoms

29 PTSD and Comorbidity in the NCS PTSD elevated the odds of comorbidity in men & women
30 Social Support Issues To disclose or not to disclose. (Bolton et al Self-disclosure about events to significant others/ military personnel was related to lower levels of PTSD severity. The reactions to self-disclosure by partner/spouse, family, friends, and other military personnel were significantly associated with PTSD symptoms severity. In each instance, more positive reactions were related to lower levels of PTSD symptoms severity.
31 Social Support Issues To disclose or not to disclose. (Bolton et al Social Support Issues To disclose or not to disclose? (Bolton et al., 2003), Cont.No differences were detected in PTSD symptoms between veterans whose disclosures were met with an overall negative or nonvalidating response and those who did not disclose at all.This later finding suggests that negative or nonvalidating responses by other to self-disclosure may negate the potentially beneficial effects of discussing the experience.However, it may also indicate that there are equally negative effects of not disclosing when the alternative is disclosure followed by a negative response.
