The purpose of this study is to compare the effectiveness of two cognitive behavioral group psychotherapy interventions in controlling the subjective sleep disturbance in veterans with Post-traumatic Stress Disorder.
Repetitive, stereotypical nightmares and insomnia commonly characterize post-traumatic stress disorder (PTSD). Identifying the pathophysiological mechanisms of disrupted sleep in PTSD has therefore assumed considerable clinical importance. We previously reported an increase in rapid eye movement activity (REM activity) during REM sleep (REMS) in Vietnam War combat veterans with PTSD, and this finding can be seen as consistent with the view that most, although not all, dreaming occurs during REMS and the repeated observation that REM activity correlates with the intensity of dream mentation. There is a growing body of evidence that post-traumatic nightmares can respond to psychological treatment interventions. Namely, a cognitive-behavioral technique entitled imagery rehearsal (IR) has been reported to be effective in the treatment of such nightmares in victims of crime and in women who have been sexually assaulted. In a small pilot study, it has also been reported to be effective in the treatment of Vietnam veterans with combat-related PTSD. The two objectives of this proposal are: 1. To compare, in a study with random assignment and a parallel group design, the effectiveness in controlling the subjective sleep disturbance in veterans with PTSD of IR and Sleep and Nightmare Management (SN), a psychological treatment that targets life stressors and problems with sleep hygiene that may exacerbate insomnia and nightmares. 2. In a subset of these subjects, to compare the effectiveness in reducing REM activity of IR and SN.

This self-report questionnaire assesses psychosocial impairment attributed to nightmares. Eleven self-report questions are rated on a scale of zero to four. The individual scores are summed to produce a total score ranging from 0 to 44 (reported in the Table). Higher scores reflect greater impairment. |
| Baseline and 1, 3, and 6 months post-treatment |
| PTSD Military Checklist | Seventeen items indicating the 17 DSM-IV criteria for PTSD are rated on a 5-point scale, from 1 to 5. Scores range from 17 to 85, with a higher score indicating greater symptom severity. | Baseline and 1, 3, and 6 months post-treatment |
| Beck Depression Inventory | Twenty-one items are rated on a 4-point scale. Total scores range from zero to 63, with higher scores indicating more severe depression. | Baseline and 1, 3, and 6 months post-treatment |
| SF-36 Physical Component | The Health Assessment Questionnaire Short Form 36 (SF-36) determines participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Scales 1-4 primarily contribute to the physical component summary score (PCS) of the SF-36. Scores on each scale are summed and averaged (range = 0 "worst"-100 "best"). | Baseline and 1, 3, and 6 months post-treatment |
