Introduction Previous studies have shown that sleep problems are commonly reported during treatment for substance use disorders (SUDs) and sleep complaints have been linked to subsequent relapse. However, most of these findings were in well-controlled clinical trials and may not generalize to the public. Little is known about the natural progression of sleep complaints during treatment in community clinics, the most common treatment approach for SUDs. The aim of this study is to longitudinally assess prevalence of clinically significant sleep disturbance at baseline and post-treatment in a community-based intensive outpatient (IOP) SUD treatment program using a multi-method approach with well-validated measures of sleep. Methods Adults beginning IOP SUD treatment completed the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Nightmare Disorder index (NDI), and one week of actigraphy and sleep diaries. Measures were repeated following treatment (approximately 5 weeks later). Results Preliminary analyses on 21 adults who have been enrolled thus far revealed 85.6% of participants experienced sleep disturbance (PSQI > 5) at baseline. 28.5% of participants reached cutoff for moderate-to-severe insomnia symptoms (ISI > 15) and 42.9% reported nightmares more than once per week. Sleep parameters taken from actigraphy and sleep diaries revealed mean sleep efficiency was 77.5% (TST M = 6.2 hours; TIB M = 7.9 hours). These variables did not improve from baseline to post-treatment. Further, most measures indicated a worsening of sleep, though this did not reach significance (all ps > .05). Conclusion This preliminary data show a high prevalence of self-reported sleep complaints and objectively measured poor sleep efficiency that do not improve over the course of treatment. Data collection is ongoing and expected to at least double. More robust analyses, including differences between SUD type (e.g., cannabis vs. opioid) and relationship to relapse at post-treatment, will then be completed. Support K12DA031794

Introduction Chronic insomnia is a common, debilitating disorder and a risk factor for significant medical morbidity, mental health problems, and workplace difficulties. Cognitive behavioral therapy for insomnia (CBT-I) is the gold standard treatment for insomnia. However, few providers are trained in CBT-I, in part due to a bottleneck in training availability and the time and cost associated with current training platforms. To address this training deficit, our team developed and evaluated CBTIweb.org, a web-based provider training course for CBT-I. Methods Feedback from alpha- and beta-testing of CBTIweb.org was collected and used to optimize course content and functionality. Then, a comparison study was conducted in which licensed providers were randomized to complete either the online CBTIweb.org course (n=21) or an in-person CBT-I training (n=23). During all phases of development, providers completed a Computer System Usability Questionnaire (CSUQ), investigator-developed website usability and content questionnaires, and pre/post-training competency assessments. Results Independent samples t-tests indicated significant improvements in CSUQ, and website usability and content questionnaires responses from alpha- to beta-testing (all ps < .05). Linear mixed-effects modeling revealed significant within-subject increases in knowledge acquisition (F(34.7) = 65.4, p < 0.001; baseline = 69% correct, post-training = 92% correct) when collapsed across in-person and web-based groups. The interaction group by time interaction was non-significant (F(34.7) = 1.7, p = 0.204), indicating similar gains in knowledge (i.e., equivalence) between the in-person and the CBTIweb.org training formats. Conclusion Alpha and beta testers of CBTIweb.org reported high levels of satisfaction while also noting areas for improvement, which were used to update the site. Findings suggest the final CBTIweb.org product successfully trained clinicians compared to an in-person workshop, given knowledge acquisition improvements. CBTIweb.org is an efficient and effective training platform for clinicians to gain knowledge and competence in the most effective treatment for insomnia. Support W81XWH-17-1-0165
