Trauma and Stressor Related disorders Acute stress disorder Post traumatic stress disorder
Prevalence of Exposure to Traumatic Events 50%-90% of general population are exposed to traumatic events during their lifetime. 75% of law enforcement personnel are exposed to traumatic events in their career. Most do not develop ASD or PTSD
What is the normal response to a traumatic event? anxiety, feeling revved up; emotional instability fatigue irritability hyper-vigilance trouble sleeping exaggerated startle response change in appetite feeling overwhelmed impatience isolation from family and friends shock nightmares somatic complaints
Acute Stress Disorder Criterion A: Directly experiencing the traumatic event Criterion B: Presence of at least 9 (or more)of the following symptoms from any of the 5 categories of: Intrusion, negative mood, dissociation, avoidance, and arousal, beginning or worsening after the traumatic event(s) occurred.
Acute Stress Disorder Criterion C: Duration of the disturbance (symptoms in Criterion B) is 3 days to 1 month after trauma exposure. Looks at emotional reactions to a distressing event other than looking primarily at fear.
Intrusion Recurrent, involuntary, and intrusive distressing memories of the traumatic event Recurrent, distressing dreams of the event Dissociative reactions (flashbacks) where individual feels or acts as if the event were recurring Intense psychological or physiological distress in response to internal/external cues that represent aspects of the event
Negative Mood Persistent inability to experience positive emotions
A subjective sense of numbing, detachment, or absence of emotional responsiveness A reduction in awareness of his/her surrounding Disassociation
Disassociation Derealization Depersonalization Dissociative amnesia
Avoidance Avoids thoughts, feelings, or conversations associated with the trauma Avoids activities, places, or people that arouse recollection of the trauma Inability to recall an important aspect of the trauma Feelings of detachment or estrangement from others
Arousal Difficulty falling asleep Irritability or outbursts of anger Difficulty concentrating Hypervigilience Exaggerated startle response
Prevalence Rates for ASD Identified in less than 20% of cases following traumatic events that do not involve interpersonal assault Higher rates (20%-50%) are reported following interpersonal traumatic events, including assault, rape, and witnessing/involved a shooting
Prevalence Rates for ASD More prevalent in females than males Risk factors include: prior mental disorder, high levels of negative affectivity (neuroticism), greater perceived severity to traumatic experience, and avoidant coping styles.
Initial Assessment Factors affecting risk of onset of traumaticassociated illness Proximity to traumatic event Similarity to victim (actual versus vicarious experience) How helpless did the individual feel Extent of social support will greatly influence prognosis Exposure to stressors in past 6 months History and family history of mental illness
