RESUMO
Sleep disturbances are among the most commonly reported posttraumatic stress disorder (PTSD) symptoms. It is essential to conduct a careful assessment of the presenting sleep disturbance to select the optimal available treatment. Cognitive-behavioral therapies (CBTs) are at least as effective as pharmacologic treatment in the short-term and more enduring in their beneficial effects. Cognitive-behavioral treatment for insomnia and imagery rehearsal therapy have been developed to specifically treat insomnia and nightmares and offer promise for more effective relief of these very distressing symptoms. Pharmacotherapy continues to be an important treatment choice for PTSD sleep disturbances as an adjunct to CBT, when CBT is ineffective or not available, or when the patient declines CBT. Great need exists for more investigation into the effectiveness of specific pharmacologic agents for PTSD sleep disturbances and the dissemination of the findings to prescribers. The studies of prazosin and the findings of its effectiveness for PTSD sleep disturbance are examples of studies of pharmacologic agents needed in this area. Despite the progress made in developing more specific treatments for sleep disturbances in PTSD, insomnia and nightmares may not fully resolve.

This study assessed rates of imaginal exposure therapy (ET) utilization and completion of cognitive behavioral therapy (CBT) for posttraumatic stress disorder (PTSD) in a clinical setting and examined variables associated with CBT completion. Using a clinical definition, the completion rate of CBT was markedly lower than rates reported in randomized trials. CBT completion was inversely related to severity of overall pretreatment measures of PTSD, avoidance, hyperarousal, depression, impaired social functioning, and borderline personality disorder. Regression yielded avoidance and depression as unique predictors of completion. Most dropouts occurred before starting imaginal ET, although initiating ET was associated with greater likelihood of completion. Results highlight methodological differences between research and practice notions of treatment completion and the need for further study of variables influencing CBT completion in practice settings.
