Role of Sleep in Exposure Therapy for Posttraumatic Stress Disorder in OIF/OEF Combat Veterans

Abstract / Description
Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed...
Show moreExposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in the LSDS group exhibited faster habituation to their traumatic memories and reported less PTSD symptomatology during and following treatment relative to participants in the HSDS group. These findings indicate that individuals with combat-related PTSD reporting less disturbed sleep experience greater extinction learning during exposure therapy. Thus, incorporating interventions that target PTSD-related sleep disturbances may be one way to maximize exposure therapy outcomes in service members with PTSD.

Psychopathology and Functional Impairment in Adolescents with Social Anxiety Disorder

Psychopathology and Functional Impairment in Adolescents with Social Anxiety Disorder.

Abstract / Description
Although social anxiety disorder is most often diagnosed during adolescence, few investigations have examined the clinical presentation of this disorder exclusively in adolescents. Prior studies have demonstrated that some clinical features of SAD in adolescents are unique relative to younger children with the condition. Furthermore, the extant literature on daily functional impairment in this population is limited. In this investigation, multiple areas of functioning were examined in...
Show moreAlthough social anxiety disorder is most often diagnosed during adolescence, few investigations have examined the clinical presentation of this disorder exclusively in adolescents. Prior studies have demonstrated that some clinical features of SAD in adolescents are unique relative to younger children with the condition. Furthermore, the extant literature on daily functional impairment in this population is limited. In this investigation, multiple areas of functioning were examined in adolescents with SAD (n = 16) and normal control adolescents (n = 14): specific social skills, subjective distress and physiological reactivity during one speech performance task and one social interaction task; alcohol use and expectancies; subjective and objective quality of sleep; and daily distressing social activities. No differences were observed in sleep actigraphy, self-reported sleep difficulties, alcohol use, or alcohol expectancies. Adolescents with SAD reported greater distress during both analogue tasks relative to NC adolescents. During the speech task, adolescents with SAD exhibited significantly greater speech latency (4.42 seconds vs. 1.75 seconds) and spoke significantly less (83.09 seconds vs. 167.75 seconds) than NC adolescents. Additionally, SAD participants manifested greater skin conductance during the speech task. During the social interaction, adolescents with SAD asked significantly fewer questions (2.20 vs. 7.07) and required significantly more confederate prompts (2.33 vs. 1.14) to stimulate interaction. Finally, adolescents with SAD reported more frequent anxiety-provoking situations in their daily lives and greater avoidance of these situations, including answering questions in class, assertive communication, and interacting with a group. The findings are discussed with respect to the current understanding of alcohol use, quality of sleep, and social functioning in adolescents with SAD.
