Sleep disruption appears not only to reflect a symptom of posttraumatic stress disorder (PTSD), but also a unique vulnerability for its development and maintenance. Studies examining the impact of psychosocial treatments for PTSD on sleep symptoms are few and no studies to date of which we are aware have examined this question in samples with co-occurring substance use disorders. The current study is a secondary analysis of a large clinical trial comparing 2 psychological treatments for co-occurring PTSD and substance use disorders. Women (N = 353) completed measures of PTSD at baseline, end of treatment, and 3-, 6-, and 12-month follow-ups. Results indicated that the prevalence of insomnia, but not nightmares, decreased during treatment, and that 63.8% of participants reported at least 1 clinical-level sleep symptom at the end of treatment. Improvement in sleep symptoms during treatment was associated with better overall PTSD outcomes over time, χ2(1) = 33.81, p < .001. These results extend the existing literature to suggest that residual sleep disruption following PTSD treatment is common in women with co-occurring PTSD and substance use disorders. Research on the benefits of adding sleep-specific intervention for those with residual sleep disruption in this population may be a promising future direction.

標題:創傷後壓力症和物質濫用的共病治療中睡眠障礙的改變。

撮要:睡眠障礙除了是創傷後壓力症(PTSD)的症狀,亦獨特地影響它的發展和持續性。針對PTSD睡眠症狀的心理社會治療研究很少,而探討與物質濫用共病樣本的相關研究更是未有的。本研究是一個比對兩種治療PTSD共病物質濫用的心理治療的大型研究二次分析。全部樣本為女性(N=353), 並完成在:基準、治療結束、三個月、六個月及十二個月覆診期的PTSD 量度。結果顯示在治療期間失眠(而非惡夢)流行率下降,而63.8%人在治療結束時有最少一種臨床睡眠症狀。治療中睡眠症狀改進與綜合PTSD結果變好有相關,X2=33.81, p< .001。研究結果加強現存文庫中患上PTSD 共病物質濫用的婦女在PTSD 治療後殘存睡眠障礙的實證。未來研究應對殘存睡眠障礙的PTSD共病物質濫用者添加特定睡眠介入治療的益處作探討。
