Objective: Insomnia, characterized by difficulty falling and staying asleep, is a common and debilitating symptom of posttraumatic stress disorder (PTSD) that is resistant to first-line, trauma-focused therapies. Previous research has found that sleep-directed hypnosis improves subjective sleep quality, particularly sleep onset latency, in women with PTSD. However, it cannot be assumed that improvements in subjective sleep reports correspond with objectively measured sleep improvements, because research has indicated a lack of agreement across these measures. The current study examined the effects of sleep-directed hypnosis plus cognitive processing therapy (hypCPT) on objective indices of sleep quality measured with actigraphy. Method: Forty-five women with PTSD were randomized to receive sleep-directed hypCPT or sleep and psychiatric symptom monitoring plus CPT (ssmCPT). Pre- and posttreatment, participants completed 1 week of daily actigraphy assessments of nocturnal sleep onset latency, waking after sleep onset, and total sleep time. Results: Overall improvement in objective sleep indices was not observed. Despite this, at posttreatment, treatment completers receiving hypCPT took significantly less time to fall asleep than did women receiving ssmCPT. Conclusions: More research is needed to understand and reduce the discrepancy between subjectively and objectively assessed sleep impairments in PTSD. Nevertheless, results indicate that adding sleep-directed hypnosis to trauma-focused therapy may be of some use for individuals with PTSD-related insomnia.
