NCT ID: NCT00183430

Last Updated: 2018-06-14

Results Overview

The Clinical Global Impression of Change is a 7-point scale that rates global change compared to baseline (1=markedly improved, 2=moderately improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=moderately worse, 7=markedly worse). The Clinical Global Impression of Change is used to determine the impact of treatment effects on meaningful and distinct change in overall sense of well-being and functioning. This outcome measure evaluates change from Baseline to Week 8.

Population: Number of participants analyzed equals the number of participants who were able to complete this assessment at Week 4.

Item B-2 "recurrent distressing dreams of the event" is a single item from teh Clinician Administered PTSD Scale (CAPS). The rating consists of two parts: Frequency plus Intensity. Symptom frequency rated 0 to 4. Symptom intensity rated 0 to 4. Frequency plus Intensity ratings equal the total score. The total minimum score = zero. The total maximum score = 8. A higher score is worse; a lower score is better. This outcome measure evaluates the change in score from Baseline to Week 8.

Pittsburgh Sleep Quality Index is a self-report questionnaire assessing sleep quality and disturbances over a 1-month time interval. A global score is obtained by summing the seven component subscales (total score range: 0-21). A score of 5 or less indicates good sleep quality. A score of more than 5 indicates poor sleep quality. Change is measured from Baseline to Week 8.
