Treating acute stress disorder: an evaluation of cognitive behavior therapy and supportive counseling techniques.
OBJECTIVE: Acute stress disorder permits an early identification of trauma survivors who are at risk of developing chronic posttraumatic stress disorder (PTSD). This study aimed to prevent PTSD by an early provision of cognitive behavior therapy. Specifically, this study indexed the relative efficacy of prolonged exposure and anxiety management in the treatment of acute stress disorder. METHOD: Forty-five civilian trauma survivors with acute stress disorder were given five sessions of 1) prolonged exposure (N = 14), 2) a combination of prolonged exposure and anxiety management (N = 15), or 3) supportive counseling (N = 16) within 2 weeks of their trauma. Forty-one trauma survivors were assessed at the 6-month follow-up. RESULTS: Fewer patients with prolonged exposure (14%, N = 2 of 14) and prolonged exposure plus anxiety management (20%, N = 3 of 15) than supportive counseling (56%, N = 9 of 16) met the criteria for PTSD after treatment. There were also fewer cases of PTSD in the prolonged exposure group (15%, N = 2 of 13) and the prolonged exposure plus anxiety management group (23%, N = 3 of 13) than in the supportive counseling group (67%, N = 10 of 15) 6 months after the trauma. Chronic PTSD in the supportive counseling condition was characterized by greater avoidance behaviors than in the prolonged exposure condition or the prolonged exposure plus anxiety management condition. CONCLUSIONS: These findings suggest that PTSD can be effectively prevented with an early provision of cognitive behavior therapy and that prolonged exposure may be the most critical component in the treatment of acute stress disorder.
Conscious and preconscious processing of food, body weight and shape, and emotion-related words in women with anorexia nervosa.
OBJECTIVE: The present study was conducted to extend prior research on attention toward food and body weight and shape-related stimuli in women with eating disorders. METHOD: A modified Stroop color-naming task was completed by women with anorexia nervosa and by control females subdivided on a measure of dietary restraint. Eating disorder-relevant word categories included words connoting fatness, words connoting thinness, low caloric density food words, high caloric density food words, and neutral, control words. Valence effects were controlled for by including positively and negatively valenced emotion words. Stimuli were presented under both unmasked and masked conditions. RESULTS: Using unmasked stimuli, patients with anorexia nervosa, but not unrestrained or restrained eaters, had delayed color-naming latencies for both thin and fat word categories and, to a lesser extent, for high caloric density food words. No differences were observed with masked stimuli. DISCUSSION: Our findings suggest that both thinness and fatness are especially salient to women with anorexia. The lack of effects for emotion words suggests that these findings do not reflect a valence effect. We found no evidence for preconscious attentional biases in the masked condition.
Treatment of acute stress disorder: a comparison of cognitive-behavioral therapy and supportive counseling.
Acute stress disorder (ASD) is a precursor of chronic posttraumatic stress disorder (PTSD). Twenty-four participants with ASD following civilian trauma were given 5 sessions of either cognitive-behavioral therapy (CBT) or supportive counseling (SC) within 2 weeks of their trauma. Fewer participants in CBT (8%) than in SC (83%) met criteria for PTSD at posttreatment. There were also fewer cases of PTSD in the CBT condition (17%) than in the SC condition (67%) 6 months posttrauma. There were greater statistically and clinically significant reductions in intrusive, avoidance, and depressive symptomatology among the CBT participants than among the SC participants. This study represents the 1st demonstration of successful treatment of ASD with CBT and its efficacy in preventing chronic PTSD.
