Abstract
Sleep significantly impacts health. Insomnia, characterized by difficulty with sleep onset, maintenance, and subsequent daytime symptoms, is increasingly prevalent and increases the risk of other medical comorbidities. The pathophysiology involves hyperarousal during non-REM sleep and altered sleep homeostasis. The 3P model explains the development and persistence of insomnia. Assessment is primarily clinical and based on appropriate history while distinguishing from other sleep disorders. "Somnomics" suggests a personalized approach to management. Cognitive behavioral therapy for insomnia is the first-line treatment in addition to other nonpharmacological strategies. Medications are a secondary option with weak supporting evidence.

New-perspective on economic evaluations: a systematic review and meta-analysis. Sleep 2024:zsae122. [PMID: 38795362 DOI: 10.1093/sleep/zsae122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Indexed: 05/27/2024] Open
Abstract
STUDY OBJECTIVES To investigate the cost-effectiveness of cognitive behavioral therapy for insomnia (CBTI), with an additional focus on digital cognitive behavioral therapy for insomnia (dCBTI) in adults with insomnia. METHODS We searched eight electronic databases for economic evaluations of CBTI: PubMed, Scopus, Web of Science, psycINFO, Cochrane, Library, CINAHL, ProQuest and National Health Service Economic Evaluation Database. Meta-analyses were performed to investigate the effects and costs between CBTI and control groups (no treatment, other treatments included hygiene education and treatment as usual). Subgroup analyses for dCBTI were conducted. RESULTS Twelve randomized controlled trails studies between 2004 and 2023 were included in our systematic review and meta-analyses. The incremental cost-utility ratios and incremental cost-effectiveness ratios showed that the CBTI and dCBTI groups were more cost-effective than controls, from healthcare perspective and societal perspective, respectively. Compared to controls, CBTI demonstrated significantly better efficacy within 12 months. Healthcare costs were significantly higher in the CBTI groups compared to the controls within 6 months but there was no difference at 12 months. Additionally, dCBTI was associated with significantly lower presenteeism costs compared to controls at 6 months. CONCLUSIONS Our findings suggest that CBTI is more cost-effective than other treatments or no treatment for adults with insomnia. It may bring more economic benefits in the long-term, especially in long-lasting efficacy and costs reduction. In addition, dCBTI is one of the cost-effective options for insomnia.

Abstract
BACKGROUND Cognitive behavioral therapy for insomnia (CBT-I) is among the recommended non-pharmacological treatments for patients with insomnia. While there are multiple reports on the effects of CBT-I treatment, few studies evaluating the factors associated with the treatment response to CBT-I have been reported. The present study aimed to confirm the effects of CBT-I in patients with insomnia and to examine the clinico-demographic factors that can predict the outcomes of CBT-I in these patients. METHODS Overall, 62 patients were included in the present study. To confirm the effectiveness of CBT-I, we compared the pre- and post-CBT-I therapy values of several sleep parameters. Furthermore, to identify the clinico-demographic factors that could be predictive of the treatment response to CBT-I, we performed generalized linear model (GLM) analysis. RESULTS The values of several sleep parameters were significantly lower after treatment than at baseline. The results of the GLM analysis revealed that sex and occupation were significantly associated with the treatment response to CBT-I. CONCLUSIONS The present results suggest that several clinico-demographic factors should be considered in the treatment of patients with insomnia.

Abstract
BACKGROUND People with chronic obstructive pulmonary disease (COPD) and insomnia experience multiple co-occurring symptoms, but no studies have examined symptom cluster change over time in this population. OBJECTIVES This study explored longitudinal patterns of symptom cluster profiles for adults with COPD and insomnia and evaluated whether behavioral interventions were associated with changes in symptom cluster profiles. METHODS This study included 91 adults with COPD and insomnia who participated in a randomized trial of cognitive behavioral therapy for insomnia (CBT-I) and COPD education. The pre-specified symptom cluster included insomnia, dyspnea, fatigue, anxiety, and depression. Latent profile analysis identified participant groups with distinct symptom cluster profiles at baseline, immediately post-intervention, and at 3-month follow-up; latent transition analysis then estimated the probability of group membership change over time. Multinomial logistic regression was used to determine whether the interventions were associated with changes in symptom cluster profiles. RESULTS Three groups were identified at each of three time-points: Class 1 (low symptom burden), Class 2 (intermediate), and Class 3 (high). Classes 1 and 2 showed less movement to other classes (16 % and 38 %, respectively), whereas Class 3 showed greater transition (64 %). The CBT-I intervention was significantly associated with movement to a lower symptom burden group (Class 3 to 2 or 2 to 1). CONCLUSIONS CBT-I, with or without COPD education, shows promise as a tailored intervention to reduce symptom burden in the study population. Study findings will facilitate development of interventions to reduce the severity of multiple co-occurring symptoms in people with COPD and insomnia.

Abstract
This article reviews the literature on mood disorders and sleep disorders among children and adolescents. Research suggests that sleep plays an important role in the development, progression, and maintenance of mood disorder symptoms among children and adolescents. Sleep problems as early as maternal perinatal insomnia may predict and predate depression among youth. Children and adolescents who develop comorbid mood disorders and sleep problems represent a particularly high-risk group with more severe mood episode symptoms, higher rates of self-harm and suicidality, and less responsivity to treatment. Treatment research supports the idea that sleep problems can be improved through behavioral interventions.

Abstract
Insomnia plays a critical role in the onset and maintenance of Major Depressive Episode (MDE). Cognitive behavioral therapy for insomnia (CBT-I) can successfully improve the sleep of patients with insomnia and MDE. Nonetheless, the factors influencing CBT-I's effects in MDE remain uncertain. This study aimed to identify predictors of insomnia improvement following CBT-I, as well as predictors of insomnia response, remission in patients with MDE and specific insomnia subtypes. Initially, we compared a 4-session weekly CBT-I treatment to baseline sleep education (SE) in a control group. This confirmed CBT-I's positive effects and the need to explore predictive factors. Notably, treatment-resistant depression (TRD) predicted reduced insomnia severity with CBT-I. Patients exhibiting seasonal fluctuations in depressive symptoms and sleep patterns throughout the year, or having daytime dysfunction, experienced enhanced CBT-I efficacy, especially for early awakenings insomnia. Conversely, shorter sleep duration predicted a less favorable response to CBT-I, less improvement in daytime dysfunction and sleep disturbance worries. Additionally, MDE with suicide attempts predicted a poorer improvement of daytime dysfunction. Further research is essential to comprehensively grasp the mechanisms behind CBT-I's heightened effectiveness in MDE patients with TRD and seasonal fluctuations.

Abstract
OBJECTIVE/BACKGROUND Digital cognitive behavioral therapy for insomnia (dCBT-I) improves several sleep and health outcomes in individuals with insomnia. This study investigates whether changes in Dysfunctional Beliefs and Attitudes about Sleep (DBAS) during dCBT-I mediate changes in psychological distress, fatigue, and insomnia severity. PATIENTS/METHODS The study presents a secondary planned analysis of data from 1073 participants in a randomized control trial (Total sample = 1721) of dCBT-I compared with patient education (PE). Self-ratings with the Dysfunctional Beliefs and Attitudes about Sleep (DBAS), the Hospital Anxiety Depression Scale (HADS), the Chalder Fatigue Scale (CFQ), and the Insomnia Severity Index (ISI) were obtained at baseline and 9-week follow-up. Hayes PROCESS mediation analyses were conducted to test for mediation. RESULTS AND CONCLUSION sDBAS scores were significantly reduced at 9-week follow-up for those randomized to dCBT-I (n = 566) compared with PE (n = 507). The estimated mean difference was -1.49 (95% CI -1.66 to -1.31, p < .001, Cohen's d. = 0.93). DBAS mediated all the effect of dCBT-I on the HADS and the CFQ, and 64% of the change on the ISI (Estimated indirect effect -3.14, 95% CI -3.60 to -2.68) at 9-week follow-up compared with PE. Changes in the DBAS fully mediated the effects of dCBT-I on psychological distress and fatigue, and the DBAS partially mediated the effects on insomnia severity. These findings may have implications for understanding how dCBT-I works and highlights the role of changing cognitions in dCBT-I.

Abstract
Sleep initiation and maintenance problems are common in the pediatric population and while behavioral interventions are recommended, their efficacy remains to be evaluated in clinical trials. We conducted a systematic review and network meta-analysis to assess the efficacy of non-pharmacological treatments and melatonin for sleep initiation and maintenance problems in healthy pediatric populations. We included 30 studies in the systematic review and 15 in the meta-analysis. Three network meta-analyses were conducted for sleep onset latency (SOL), wake after sleep onset (WASO), and total sleep time (TST). For SOL variable, the results support greater effectiveness of light therapy and melatonin than evidence-based psychological interventions, whether implemented in combination with light therapy or not. Regarding WASO variable, evidence-based psychological interventions and a combination of those techniques plus light treatment were the most efficacious. Finally, for TST variable, a larger effect was shown for the combined treatment of evidence-based psychological intervention with light therapy in comparison to other interventions. In conclusion, we found a high variability between study protocols likely impacting the results of the meta-analysis. Future randomized control trials studies, stratified by pediatric age classes, are needed in order to provide clear suggestions in clinical settings.

Abstract
BACKGROUND Despite its efficacy in treating comorbid insomnia and depression, cognitive behavioral therapy for insomnia (CBT-I) is limited in its accessibility and, in many countries, cultural compatibility. Smartphone-based treatment is a low-cost, convenient alternative modality. This study evaluated a self-help smartphone-based CBT-I in alleviating major depression and insomnia. METHODS A parallel-group randomized, waitlist-controlled trial was conducted with 320 adults with major depression and insomnia. Participants were randomized to receive either a 6-week CBT-I via a smartphone application, proACT-S, or waitlist condition. The primary outcomes included depression severity, insomnia severity, and sleep quality. The secondary outcomes included anxiety severity, subjective health, and acceptability of treatment. Assessments were administered at baseline, post-intervention (week 6) follow-up, and week 12 follow-up. The waitlist group received treatment after the week 6 follow-up. RESULTS Intention to treat analysis was conducted with multilevel modeling. In all but one model, the interaction between treatment condition and time at week 6 follow-up was significant. Compared with the waitlist group, the treatment group had lower levels of depression [Center for Epidemiologic Studies Depression Scale (CES-D): Cohen's d = 0.86, 95% CI (-10.11 to -5.37)], insomnia [Insomnia Severity Index (ISI): Cohen's d = 1.00, 95% CI (-5.93 to -3.53)], and anxiety [Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A): Cohen's d = 0.83, 95% CI (-3.75 to -1.96)]. They also had better sleep quality [Pittsburgh Sleep Quality Index (PSQI): Cohen's d = 0.91, 95% CI (-3.34 to -1.83)]. No differences across any measures were found at week 12, after the waitlist control group received the treatment. CONCLUSION proACT-S is an efficacious sleep-focused self-help treatment for major depression and insomnia. TRIAL REGISTRATION ClinicalTrials.gov, NCT04228146.

Abstract
Cognitive behavioral therapy for insomnia (CBT-I) is a first-line treatment for insomnia disorder. Herein, we reviewed the currently prevailing forms of application of CBT-I and the corresponding studies on their health economics, comparing them with medication treatment. At present, most of the findings suggest that CBT-I has long-lasting effects and can help reduce future medical costs, thus showing long-term economic advantages. At present, there are no relevant research reports on the economic benefits of CBT-I in China. This review could provide reference for relevant studies to be conducted in the future in China. In addition, it provides reference from an economic perspective for clinicians and patients and facilitates their decision-making concerning using CBT-I as a treatment option for insomnia in the future.

Abstract
OBJECTIVE To describe (1) self-care trajectories among adults with heart failure (HF) and insomnia over 1-year; (2) the extent to which trajectories varied between cognitive behavioral therapy for insomnia (CBT-I) or HF self-care intervention; and (3) the associations between self-care trajectories and clinical and demographic characteristics, sleep, symptoms and stress, and functional performance. METHODS We conducted secondary analysis of data from a randomized controlled trial of the effects of CBT-I compared with HF self-care education among adults with stable HF and insomnia. We used the Self-Care of Heart Failure Index v6.2. The analytic approaches included t-tests, group-based trajectory modeling, ANOVA, and chi-square. RESULTS We included 175 participants (M age=63.0 (12.9) years, White, N = 100]. We found four self-care trajectories: Low self-care (N = 47, 26.8%); Moderate self-care (N = 68, 38.9%): Adequate self-care (N = 42, 24.0%); and Optimal self-care (N = 18, 10.3%). There was no difference in self-care trajectories between interventions. The low self-care group had the most severe baseline fatigue, anxiety, and perceived stress, and lowest cognitive abilities. CONCLUSION Both interventions prevented declining self-care. Future research is needed to determine the most efficacious intervention to improve self-care trajectories. PRACTICE IMPLICATIONS Healthcare providers should provide ongoing self-care support for those with persistently low and moderate self-care.

Abstract
Cognitive behavioral therapy for insomnia (CBT-I) is effective for not only primary insomnia (PI) but also comorbid insomnia (CI; insomnia associated with psychiatric/physical diseases or other types of sleep disorders). This study aimed to compare the outcomes of CBT-I implemented in the same manner between patients with PI and CI. In total, 41 adult patients who had completed CBT-I were enrolled in this retrospective analysis and divided into a PI group and a CI group. The authors then examined and compared the significance of changes after therapy between the two groups. The magnitude of improvement on the Japanese version of the Insomnia Severity Index (ISI-J) was analyzed as the primary endpoint. In the PI group (n = 24), both the ISI-J score and the dose of hypnotics decreased significantly following CBT-I. On the other hand, in the CI group (n = 17), only the dose of hypnotics decreased significantly; no statistically significant improvement was seen in the ISI-J score. Sleep onset latency and sleep quality rating in recorded sleep diaries were significantly correlated with improved ISI-J scores in the CI group only. CBT-I was shown to be effective for CI, but its efficacy for CI was inferior to that for PI in terms of impact on sleep and mental condition. These results suggest that in addition to the basic components of CBT-I, treatment for CI, especially when accompanied by severe insomnia symptoms, should include approaches targeting the comorbid disease.

Abstract
Borderline personality disorder (BPD) is a highly disabling psychiatric disorder with emotion dysregulation at its core, resulting in affective instability, impulsivity and sometimes self-harming or suicidal behavior. Sleep is increasingly recognized to play a crucial role in emotion regulation. BPD patients often suffer from (severe) insomnia, potentially aggravating symptoms and preventing recovery from BPD. Yet, the effects of insomnia treatments have not been investigated in context of BPD. Guided internet-based cognitive behavioral therapy for insomnia (iCBT-I; i-Sleep) has been proven effective in improving both insomnia and affective symptoms. In this randomized controlled trial among 96 patients with a DSM-5 diagnosis of BPD (or other personality disorder with ≥4 BPD traits) and insomnia symptoms, we will test the effectiveness of iCBT-I before regular BPD treatment starts, during the waitlist period, on BPD symptoms. Patients in the control group monitor their sleep through a sleep diary during the waitlist period and also receive standard BPD treatment after that. Using linear mixed models we will test the hypothesis that the iCBT-I group improves more than the control group on BPD symptoms (primary outcome), insomnia severity, additional subjective and objective sleep variables, emotion regulation, comorbid anxiety and depression complaints, and quality of life. These effects are thought to arise from a direct effect of improved sleep on emotion regulation and a synergistic effect on the consolidation and internalization of the BPD treatment effect. To our knowledge, this is the first trial assessing effectiveness of CBT-I in patients with BPD (traits). The accessibility of the studied intervention greatly facilitates clinical implication in case of positive results.

Abstract
Cognitive behavioral therapy for insomnia (CBT-I) is an effective, non-pharmacological intervention, designated by the American College of Physicians as the first-line treatment of insomnia disorder. The current randomized controlled study uses a Hybrid-Type-1 design to compare the effectiveness and implementation potential of two approaches to delivering CBT-I in primary care. One approach offers therapy to all patients through an automated, digital CBT-I program (ONLINE-ONLY). The other is a triaged STEPPED-CARE approach that uses a simple Decision Checklist to start patients in either digital or therapist-led treatment; patients making insufficient progress with digital treatment at 2 months are switched to therapist-led treatment. We will randomize 240 individuals (age 50 or older) with insomnia disorder to ONLINE-ONLY or STEPPED-CARE arms. The primary outcomes are insomnia severity and hypnotic medication use, assessed at baseline and at months 2, 4, 6, 9, and 12 after randomization. We hypothesize that STEPPED-CARE will be superior to ONLINE-ONLY in reducing insomnia severity and hypnotic use. We also aim to validate the Decision Checklist and explore moderators of outcome. Additionally, guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, we will use mixed methods to obtain data on the potential for future dissemination and implementation of each approach. This triaged stepped-care approach has the potential to improve sleep, reduce use of hypnotic medications, promote safety, offer convenient access to treatment, and support dissemination of CBT-I to a large number of patients currently facing barriers to accessing treatment.

Abstract
PURPOSE OF REVIEW With a focus on reviewing adequately powered randomized controlled trials, we present recent research on the potential of cognitive behavioral therapy for insomnia (CBT-I) to improve depression and anxiety outcomes among patients with insomnia and one of the following comorbid psychiatric disorders: major depressive disorder (MDD), generalized anxiety disorder (GAD), or posttraumatic stress disorder (PTSD). We also examine potential moderators of CBT-I on depression and anxiety outcomes in this population. RECENT FINDINGS Despite high comorbidity rates, current behavioral and pharmacological treatments for MDD, GAD, and PTSD do not substantially target or improve insomnia symptoms; residual insomnia is exceedingly common even among patients who experience remission. Insomnia plays a critical role in the onset and maintenance of depression and anxiety, and treating insomnia with CBT-I may improve global outcomes for patients with MDD, GAD, and PTSD. CBT-I is superior to traditional depression/anxiety treatment in improving insomnia symptoms among patients with comorbid psychiatric disorders. Results are mixed on whether CBT-I (either alone or augmented with depression/anxiety treatment) is effective in improving overall MDD, GAD, and PTSD outcomes. Evening circadian preference and depression/anxiety symptom severity may moderate the effect of CBT-I on depression and anxiety outcomes.

[PMID: 34902820 DOI: 10.1016/j.smrv.2021.101567] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 10/29/2021] [Accepted: 11/01/2021] [Indexed: 12/19/2022]
Abstract
The comparative efficacy of various approaches of digital cognitive behavioral therapy for insomnia (CBTi) is still unclear. This network meta-analysis explored the comparative efficacy of digital CBTi approaches in adults with insomnia. Four electronic databases were searched from inception to June 27, 2020. Primary outcomes were self-reported total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), and insomnia symptoms; these were measured using sleep diaries or valid questionnaires. A random-effects network meta-analysis in a frequentist framework was used. Fifty-four randomized controlled trials comprising 11,815 participants were included. Compared with usual care, web-based CBTi with a therapist demonstrated significantly longer TST (mean difference [MD]: 23.19 min, 95% confidence interval [CI]: 18.98-27.39 min), shorter SOL (MD: -18.76 min, 95% CI -24.20 to -13.31 min), lower WASO (MD: -31.40 min, 95% CI: -36.26 to -26.55 min), and greater SE (MD: 10.37%, 95% CI: 8.08%-12.65%). The surface under the cumulative ranking curve indicates that web-based CBTi with therapists is most likely to be ranked the highest among all treatments, and thus, this network meta-analysis suggests that such a treatment is the optimal intervention for improving sleep duration and SE as well as the reductions in SOL and WASO.

Abstract
Objectives Insomnia has widespread negative implications for health and well-being. Online delivery of mindfulness-based therapy for insomnia (MBTI) has not previously been evaluated. This study investigated the feasibility and preliminary efficacy of a digital MBTI program for improving insomnia symptoms. It was hypothesized that a 6-week digital MBTI program would reduce insomnia symptoms and pre-sleep arousal and improve mood, compared to a waitlist control condition. Methods Twenty-seven participants (M = 29.44, SD = 11.97 years) experiencing insomnia symptoms (insomnia severity index [ISI] ≥ 8) were randomized to either a 6-week intervention or waitlist condition. Participants completed the ISI, pre-sleep arousal scale (PSAS), and the positive and negative affect schedule at baseline, mid-, and post-study. Feasibility was assessed across four domains (acceptability, implementation, practicality, and preliminary efficacy) using self-reports, attrition, program completions, and module completions. Results Feasibility data for the intervention indicated that there was 22% attrition, and 79% of the modules were completed. There were significantly greater reductions in the severity of insomnia symptoms (p < .001) and both cognitive (p = .03) and somatic (p = .02) subscales of the PSAS, at post-intervention compared to the waitlist group. There were no significant group differences in mood. Conclusions This study provides preliminary evidence of the feasibility and efficacy of a digital MBTI, which may assist in the broader dissemination of insomnia treatment.Trial RegistrationAustralian and New Zealand Clinical Trials Registry: ACTRN12620000398909.

Implementation of a digital cognitive behavioral therapy for insomnia pathway in primary care. Contemp Clin Trials 2021; 107:106484. [PMID: 34129952 DOI: 10.1016/j.cct.2021.106484] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 05/03/2021] [Accepted: 06/10/2021] [Indexed: 11/20/2022]
Abstract
Background Insomnia is a prevalent and debilitating disorder commonly managed by family physicians. Insomnia guidelines recommend cognitive behavioral therapy for insomnia (CBTi) as the 'first-line' treatment. However, family physicians report limited time, knowledge, access, support, and referral options to manage patients with CBTi. Consequently, many patients with insomnia are prescribed potentially harmful and addictive sedative-hypnotic medicines (e.g. benzodiazepines). Family physicians require an insomnia management pathway that is specifically tailored to the guideline-recommendations, time demands, and capacity of family practice. Methods This mixed-methods implementation trial will test the feasibility, acceptability and effectiveness of a comprehensive digital insomnia management pathway in family practice. This novel pathway includes digital recruitment of family physicians, automatic identification of patients whose electronic medical records contain recent sedative-hypnotic prescriptions using a software management pathway and real-time notifications prompting physicians to refer patients to a well-established digital CBTi program. At least 10 family physicians and 375 patients with insomnia will be recruited. Physicians will be provided with an eBook to guide gradual sedative-hypnotic withdrawal. Feasibility and acceptability will be assessed from the perspective of patients and physicians. Effectiveness will be determined by co-primary outcomes: cessation of sedative-hypnotic use, and improvement in self-reported insomnia symptoms from baseline to 12-month follow-up. Analysis of trends in costs, cost-effectiveness and cost-utility analyses will be conducted from a societal perspective. Results and discussion This implementation trial will pave the way for future scaling-up of this insomnia management pathway to improve access to CBTi and reduce reliance on sedative-hypnotic medicines in family practice. Trial Registration: This trial was prospectively registered on the Australian and New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12619001539123).

The reliability of objective total sleep time in predicting the effectiveness of cognitive-behavioral therapy for insomnia. Sleep Med 2021; 82:43-46. [PMID: 33887556 DOI: 10.1016/j.sleep.2021.03.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/05/2021] [Accepted: 03/17/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Despite insomnia diagnosis is based only on subjective sleep assessment, recent literature suggested the usefulness of objective sleep duration for the identification of two insomnia phenotypes based on objective total sleep time (oTST). In particular, insomnia with short sleep duration (SS) (oTST<6 h) seems to receive less benefit from Cognitive-Behavioral Therapy for Insomnia (CBT-I) compared to patients with normal sleep duration (NS) (oTST≥6 h). The aim of this study is to evaluate CBT-I response of patients previously divided into SS and NS and to assess the agreement between oTST measured by polysomnography (PSG) and by actigraphy in identifying the two subgroups. METHODS Fifty-three insomnia patients (50.9% females; mean age 56.53 ± 11.43) underwent a baseline PSG and an actigraphic evaluation to identify SS and NS subjects. Insomnia Severity Index (ISI) and sleep diaries data (wakefulness after sleep onset) were considered primary outcomes. All the other sleep diaries variables were used as secondary outcomes. RESULTS Throughout PSG we identified 22 NS (41.5%) and 31 SS (58.5%) patients, whereas actigraphic evaluation identified 38 NS (71.7%) and 15 SS (28.3%) patients. All subjects showed significant improvement after treatment, however, no effect of group membership was found to influence CBT-I response. Strikingly, actigraphy and PSG differed in identifying the two subgroups. Specifically, only 27 out 53 (51%) were consistently classified as SS [K = 0.086, 95% confidence interval: -0.132 to 0.305, p = 0.448]. CONCLUSIONS Our results challenge the reliability and usefulness of oTST in predicting CBT-I effectiveness. Future studies might focus on night-to-night variability experienced by insomnia patients for the prediction of CBT-I outcomes.

Abstract
BACKGROUND Insomnia affects up to 63% of patients with cancer. Cognitive behavioral therapy for insomnia (CBT-I) is considered to be the non-pharmacological gold standard treatment, but it remains underutilized in France. Self-administered interventions offer new ways to overcome some of the barriers that restrict access to efficacious supportive care. OBJECTIVE To assess the feasibility, among French adult cancer outpatients, of a validated Quebec video-based, self-administered, cognitive behavioral therapy for insomnia (VCBT-I). METHODS A pre-post design with quantitative measures (Insomnia Severity Index, Edmonton Symptom Assessment System, Treatment Perception Questionnaire) and qualitative measures (semi-structured interviews) was used. RESULTS One hundred and seventy-three cancer outpatients were self-screened for insomnia, and 57% (n=99) reported significant symptoms. Among them, 80% (n=79) agreed to participate in the VCBT-I. The download rate of the VCBT-I was 78% (n=62/79). Several technical and contextual barriers to the delivery and the applicability of the VCBT-I emerged. However, participants reported a high level of satisfaction, and some valuable benefits at post-immediate intervention (increased knowledge about sleep, better quality of sleep, and higher acceptance of the burden of insomnia), regardless of whether or not they still had insomnia. DISCUSSION This study confirms that there is a demand for a VCBT-I, which was perceived as appropriate by a sample of French cancer outpatients with insomnia, but it also highlights some limitations in terms of implementation and practicality. Remote professional support appears to be a core need in order to address these issues and personalize the guidance process.

Abstract
BACKGROUND Cognitive behavioral therapy for insomnia (CBT-I) is a first-line therapy for insomnia disorders. We assessed changes in discrepancies between subjective and objective sleep measures and correlations between discrepancy changes and clinical insomnia severity for CBT-I in patients with primary insomnia METHODS: Fifty-two outpatients (mean age, 60.3 years; 26 women) with primary insomnia were treated by individual CBT-I (50 min, maximum six sessions, once every 1-2 weeks). One week before and after CBT-I, patients recorded a sleep log and wore an actigraphy device. Subjective and objective time in bed (TIB), total sleep time (TST), sleep-onset latency (SOL), wake time after sleep onset (WASO), and sleep efficiency (SE) were evaluated by averaging 1-week records. Relative values of sleep discrepancy in TIB, TST, SOL, WASO, and SE were calculated for estimating effects of CBT-I. The therapeutic effects were also evaluated using psychological scales before and after CBT-I. RESULTS Subjective and objective discrepancies in sleep measures decreased by 36, 25, and 37 min in TST, SOL, and WASO, respectively, and 7% in SE (all P < 0.001) after CBT-I. Seven patients transitioned from underestimating SE before CBT-I to overestimating SE after CBT-I. Although CBT-I improved relative values of discrepancy in WASO and SE, alongside ISI, the improvement in insomnia severity only correlated with SOL discrepancy. CONCLUSIONS CBT-I may reduce the discrepancy between subjective and objective sleep measures in patients with primary insomnia. However, a greater therapeutic effect of CBT-I was observed in reducing the ISI, which was slightly influenced by improvements in sleep discrepancies.

Abstract
Background Insomnia is a widespread disease in adults and has a high prevalence rate. As sleep disturbances are a risk factor concerning mental and physical health, prevention and early intervention are necessary. Thus, the aim of this study was to implement a self-learning prevention and early intervention training for university staff members. We adapted an established cognitive behavioral therapy for insomnia (CBT-I) intervention as an online version for use during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) crisis. Methods Development and adaptation procedure of the internet-based CBT‑I (iCBT-I) prevention and early intervention training is described. Sessions and topics are shown in detail. The Online Sleep Prevention and Treatment Acceptance questionnaire (OSTA) and the Online Sleep Prevention and Treatment Feedback questionnaire (OSTF) were used to assess acceptance. Sleep problems of university staff members were assessed using the Pittsburgh Sleep Questionnaire (PSQI). Results The online-adapted version consisted of seven modules. Contents of sessions and topics were implemented based on video clips. Drawings were added to information regarding sleep and sleep hygiene as well as addressing stress and cognitions. In all, 15 individuals participated in this pilot study. The new iCBT‑I self-learning prevention training was well accepted. In addition, participants scored the online version as helpful based on the OSTA. Prior to online training, 89% of the participants reported impaired sleep quality or insomnia symptoms, and 56% had a PSQI score over 10. After training 78% of participants showed reduced sleep problems according to PSQI and 56% reached clinically significant enhancement. In addition, after training 44% were healthy sleepers. Discussion This is the first iCBT‑I prevention and early intervention training for university staff members. The training by participants was very well accepted and they scored the videos as very helpful. Sleep problems decreased after online training. However, further studies with larger samples and more sleep-related assessment strategies, e.g., actigraphy and sleep log, are necessary.

Abstract
OBJECTIVE This study sought to validate the Japanese version of the Sleep Hygiene Practices Scale (SHPS-J). PATIENTS/METHODS A cross-sectional questionnaire-based study was conducted via the internet. In total, 854 participants (435 men, 419 women; mean age, 42.91 ± 11.54 years) were asked to complete all scales, and 283 of them were asked to complete the same scales two weeks later. The survey consisted of the SHPS-J, the Japanese version of the Insomnia Severity Index (ISI-J), and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). The SHPS-J was developed according to the International Society for Pharmacoeconomics and Outcomes Research Task Force for Translation and Cultural Adaption. For the analysis, participants were divided into three groups: insomnia syndrome, insomnia symptoms, and good sleep groups. RESULTS The SHPS-J had good test-retest reliability (ICC: 0.55-0.76) and adequate internal consistency (α = 0.54-0.74), except with regard to eating/drinking behaviors. The factorial validity of the four-factor structure was confirmed through a confirmatory factor analysis; however, one item related to eating/drinking behaviors had no significant factor loading. The construct validity was confirmed through a correlation analysis between each domain of the SHPS-J and ISI-J (r = 0.19-0.60, p < 0.01). The results of clinical validation confirmed that all domains of the SHPS-J were significantly higher for individuals with insomnia than for good sleepers. CONCLUSIONS This study confirmed both the reliability and validity of the SHPS-J.

Abstract
This article reviews the literature on mood disorders and sleep disorders among children and adolescents. Research suggests that sleep plays an important role in the development, progression, and maintenance of mood disorder symptoms among children and adolescents. Sleep problems as early as maternal perinatal insomnia may predict and predate depression among youth. Children and adolescents who develop comorbid mood disorders and sleep problems represent a particularly high-risk group with more severe mood episode symptoms, higher rates of self-harm and suicidality, and less responsivity to treatment. Treatment research supports the idea that sleep problems can be improved through behavioral interventions.

Abstract
The aim of the current study was to assess the feasibility and preliminary efficacy of utilizing an online Cognitive Behavioral Therapy for Insomnia (CBT-I) program in bereaved older adults (ages 55 and older). Participants were randomized to receive either a 6-week online CBT-I program or six weeks of online psychoeducational modules on insomnia and grief. The sample included 30 adults with mild to severe symptoms of insomnia. Results suggest that the study was feasible to conduct, as evidenced by the brief 5-week recruitment time, 87% retention rate, and 100% completion rate of the intervention modules. There were no treatment effects by time difference shown in the study and no significant differences in study outcomes were found between the CBT-I and control groups, as both demonstrated similar improvements in insomnia. However, this study suggests that it is feasible to recruit bereaved older adults for an online educational program and successfully administer an online protocol targeting insomnia and well-being.

Abstract
Lifestyle interventions to increase exercise and improve diet have been the focus of recent clinical trials to potentially prevent Alzheimer's disease (AD). However, despite the strong links between sleep disruptions, cognitive decline, and AD, sleep enhancement has yet to be targeted as a lifestyle intervention to prevent AD. A recent meta-analysis suggests that approximately 15% of AD may be prevented by an efficacious intervention aimed to reduce sleep disturbances and sleep disorders. Chronic insomnia is the most frequent sleep disorder occurring in at least 40% of older adults. Individuals with insomnia are more likely to be diagnosed with Alzheimer's Disease (AD) and demonstrate decline in cognitive function at long-term follow-up. AD is characterized by the accumulation of amyloid-β (Aβ) plaques and tau tangles in the brain, and growing evidence shows impaired sleep contributes to the accumulation of Aβ. An intervention aimed at improving insomnia may be a critical opportunity for primary prevention to slow cognitive decline and potentially delay the onset of AD. Cognitive behavioral therapy for insomnia (CBT-I) is an efficacious treatment for insomnia, but the use of CBT-I to improve cognitive function and potentially reduce the rate of Aβ accumulation has never been examined. Therefore, the objective of the proposed study is to examine the efficacy of CBT-I on improving cognitive function in older adults with symptoms of insomnia. An exploratory aim is to assess the effect of CBT-I on rate of Aβ accumulation.

Abstract
Background Depression is a major public health concern. Emerging research has shown that cognitive behavioral therapy for insomnia (CBT-I) is effective in treating individuals with comorbid insomnia and depression. Traditional face-to-face CBT-I encounters many obstacles related to feasibility, accessibility, and help-seeking stigma. CBT-I delivered via smartphone application could be a potential solution. This paper reports a protocol designed to evaluate the efficacy of a self-help smartphone-based CBT-I, using a waitlist group as control, for people with major depression and insomnia. Methods A two-arm parallel randomized controlled trial is conducted in a target sample of 285 non-suicidal Hong Kong Chinese older than 17 years of age with major depression and insomnia. Participants complete an online rapid screening, followed by a telephone diagnostic interview. Those who meet the eligibility criteria are randomized in a ratio of 1:1 to receive either CBT-I immediately or to a waitlist control condition. The CBT-I consists of six weekly modules and is delivered through a smartphone application proACT-S. This smartphone app has been pilot tested and revamped to improve user experience. An online randomized algorithm is used to perform randomization to ensure allocation concealment. The primary outcomes are changes over the measurement points in sleep quality, insomnia severity, and depression severity. The secondary outcomes include changes over the measurement points in anxiety, subjective health, treatment expectancy, and acceptability of treatment. Assessments are administered at baseline, post-intervention, and 6-week follow-up. The recruitment is completed. Important adverse events, if any, are documented. Multilevel linear mixed model based on intention-to-treat principle will be conducted to examine the efficacy of the CBT-I intervention. Discussion It is expected that proACT-S is an efficacious brief sleep-focused self-help treatment for people with major depression and insomnia. If proven efficacious, due to its self-help nature, proACT-S may be applicable as a community-based early intervention, thereby reducing the burden of the public healthcare system in Hong Kong.

Abstract
Insomnia is highly prevalent among patients with breast cancer (BC). Although cognitive behavioral therapy for insomnia (CBT-I) is available in integrative oncology settings, it poses unique challenges for BC survivors. Our review aimed to assess the evidence for the therapeutic effects of CBT-I on insomnia in BC. Randomized controlled trials (RCTs) that included patients/survivors with BC and insomnia, and at least one validated self-report measure of sleep quality were included in the review. Of the 14 included RCTs (total N = 1363), the most common components incorporated in CBT-I interventions were sleep hygiene, stimulus control and sleep restriction. Pooled effect sizes favored CBT-I at post-intervention (Hedges' g = -0.779, 95% CI = -0.949, -0.609), short-term follow-up (within six months, Hedges' g = -0.653, 95% CI = -0.808, -0.498), and long-term follow-up (12 mo, Hedges' g = -0.335, 95% CI = -0.532, -0.139). In sub-analyses, CBT-I had similar effect sizes regardless of potential modifiers (comparison design, delivery formats, etc.). As an integrative oncology intervention, CBT-I is efficacious for reducing insomnia and improving sleep quality in women treated for BC, with medium-to-large effect sizes that persist after intervention delivery ends. Given the variability in the CBT-I components tested in RCTs, future studies should investigate the optimal integration of CBT-I components for managing insomnia during BC survivorship.

Abstract
Background Little is known about cognitive and behavioral predictors of sleep quality and relapse among individuals with alcohol use disorder (AUD). Using the social cognitive theory (SCT), we assessed sleep-related behaviors and cognitions, sleep quality, and relapse to drinking among individuals with AUD transitioning from inpatient to outpatient settings. Method Individuals (n = 149) seeking treatment for AUD were recruited during their inpatient stay. Self-efficacy for sleep, dysfunctional beliefs about sleep, sleep-related behaviors, sleep quality, and relapse were assessed. Objective (actigraphy) assessment of sleep efficiency and duration was measured using actigraphy. Multiple logistic regression models tested whether self-reported sleep quality or sleep-related beliefs/behavior predicted relapse. Repeated measures linear mixed modeling tested whether there was a change over time in sleep quality as well as the relationships between self-efficacy, sleep-related beliefs, sleep behaviors, sleep quality, and relapse. Results In our sample, self-efficacy for sleep, dysfunctional beliefs about sleep, and sleep-related behavior were all significantly associated with both sleep quality and relapse. Controlling for pre-discharge sleep-related behaviors (SRBQ) and actigraphy-recorded average sleep time during the first week post-discharge, married participants had lower odds of relapse compared with non-married patients (p = 0.048, OR = 0.119, 95% CI 0.015–0.983). Patients with lower self-efficacy for sleep (SES) scores (p < 0.001) and higher CPRS anxiety scores (p < 0.001) had higher PSQI scores. Conclusion Our results highlight the importance of self-efficacy and dysfunctional beliefs about sleep as predictors of sleep quality and relapse among individuals with AUD and the utility of the SCT as a sleep research framework.

Abstract
BACKGROUND Major depressive disorder is among the most burdening and costly chronic health hazards. Since its prognosis is poor and treatment effectiveness is moderate at best, prevention would be the strategy of first choice. Insomnia may be the best modifiable risk factor. Insomnia is highly prevalent (4-10%) and meta-analysis estimates ±13% of people with insomnia to develop depression within a year. Among people with insomnia, recent work identified three subtypes with a particularly high lifetime risk of depression. The current randomized controlled trial (RCT) evaluates the effects of internet-guided Cognitive Behavioral Therapy for Insomnia (CBT-I), Chronobiological Therapy (CT), and their combination on insomnia and the development of depressive symptoms. METHODS We aim to include 120 participants with Insomnia Disorder (ID) of one of the three subtypes that are more prone to develop depression. In a two by two factorial repeated measures design, participants will be randomized to CBT-I, CT, CBT-I + CT or treatment as usual, and followed up for one year. The primary outcome is the change, relative to baseline, of the severity of depressive symptoms integrated over four follow-ups spanning one year. Secondary outcome measures include a diagnosis of major depressive disorder, insomnia severity, sleep diaries, actigraphy, cost-effectiveness, and brain structure and function. DISCUSSION Pre-selection of three high-risk insomnia subtypes allows for a sensitive assessment of the possibility to prevent the development and worsening of depressive symptoms through interventions targeting insomnia.

Abstract
This article reviews the literature on cognitive-behavioral therapy for insomnia in adults and adolescents with depression. Recent research has expanded on previous research, which established that sleep problems are an important predictor of depression and that sleep problems are associated with more severe depression, more suicidality, and worse outcomes for treatment of depression. The relationship between sleep problems and depression is complex, likely bidirectional, and impactful. To further improve the lives of patients with depression who experience insomnia, it will be important to investigate which patients will do better in a sequential versus concomitant approach.

Abstract
Cognitive-behavioral therapy for insomnia (CBT-I) has emerged as the first-line treatment for chronic insomnia but remains massively underused relative to the prevalence of insomnia disorder. This article focuses on 3 key issues in the delivery of CBT-I in the real world. First, where and how should CBT-I be delivered and who should deliver it? Second, who is an appropriate candidate for CBT-I? Third, how do you measure quality care with CBT-I? These issues give rise to targets for future research aimed at improving the implementation science of CBT-I in the real world.

Abstract
Abstract Alcohol use disorder (AUD) is characterized by problematic drinking that becomes severe. Individuals with AUD often experience insomnia and other sleep disturbances at various phases of recovery. Cognitive behavioral therapy for insomnia (CBT-I) is an efficacious non-pharmacological treatment for insomnia and is recommended as a first-line treatment for adults with chronic insomnia. Internet-based CBT-I could play a key role in the dissemination of this behavioral sleep intervention, given the paucity of trained clinicians able to provide CBT-I in person and other logistical/cost concerns. SHUTi (Sleep Healthy Using The Internet) is the most tested and empirically-sound Internet intervention for insomnia. Despite the promise of Internet-based CBT-I interventions, to date, no randomized controlled trials (RCTs) exist examining the feasibility/efficacy of an Internet-based CBT-I program among treatment-seeking individuals recovering from AUD. This is a two-phase RCT assessing feasibility/acceptability and efficacy of the SHUTi program among individuals with AUD in recovery with insomnia. Phase I will focus on assessing the feasibility and acceptability of program delivery and data collection (n = 10). Phase II will be an RCT powered to examine preliminary intervention efficacy (n = 30 per group). Participants for this study must meet criteria for “moderate to severe” insomnia. Individuals randomized to the intervention group will receive the SHUTi intervention (initiated while inpatient and completed while outpatient), and individuals randomized to the control group will receive an educational web-based program. The goals of the study are as follows: (1) assess the feasibility and acceptability of Internet-based CBT-I among individuals with AUD in recovery with insomnia (phase I), (2) compare the preliminary efficacy of CBT-I versus control group with respect to primary and secondary outcome variables (phase II), and (3) explore specific domains associated with improved outcomes, e.g., demographic, psychiatric, and drinking-related factors (phase II). Primary outcome measures include changes in insomnia severity over time and changes in actigraphy-recorded sleep efficiency over time. Trial registration NCT#03493958; registered 1 June 2018.

Abstract
OBJECTIVE This study determined whether cognitive behavioral therapy for insomnia (CBT-i) decreased the need for sleep medications and produced better treatment outcomes than pharmacotherapy alone. METHODS We reviewed data from patients with insomnia in the outpatient clinic of a general hospital between 2009 and 2015. We compared 41 patients who received five sessions of CBT-i with 100 age- and sex-matched patients who received pharmacotherapy only. We evaluated the change in prescription for sleep (i.e., antidepressants, hypnotics, and others) between the first and last visits using repeated measures analysis of variance (ANOVA). Clinical global impressions and completion status at the last visit were assessed using the chisquare test. RESULTS We found a significant decrease in the prescription rate and the dosage of hypnotics among patients who received CBT-i when compared with control patients. There was no significant change in the dosage of antidepressants between the two groups. Achievement of case closure was better in the CBT-i group at the trend level. Clinical global impression at the last visit was not significantly different. CONCLUSION These results show that CBT-i reduces the need for hypnotics among insomnia patients. Our results indicate that CBT-i offers additional benefits beyond improving sleep characteristics and thus provides another reason for recommending CBT-i as a first-line treatment for insomnia.

Abstract
AIMS Comorbid insomnia and obstructive sleep apnea (OSA) represents a highly prevalent and debilitating condition; however, physicians and researchers are still uncertain about the most effective treatment approach. Several research groups have suggested that these patients should initially receive treatment for their insomnia before the sleep apnea is targeted. The current study aims to determine whether Cognitive and Behavioral Therapy for Insomnia (CBT-i) can effectively treat insomnia in patients with comorbid OSA and whether its effectiveness is impaired by the presence of OSA. METHODS A retrospective chart review was conducted to examine 455 insomnia patients entering a CBT-i treatment program in a hospital out-patient setting. Three hundred and fourteen patients were diagnosed with insomnia alone and 141 with insomnia and comorbid OSA. Improvements in average sleep diary parameters, global insomnia severity, and several daytime functioning questionnaires from baseline, to post-treatment, to 3-month follow-up were compared between insomnia patients with and without comorbid OSA. RESULTS Insomnia patients with comorbid OSA experienced significant improvements in insomnia symptoms, global insomnia severity, and other daytime functioning measures during and following treatment. Furthermore, improvements were no different between patients with or without comorbid OSA. Sleep apnea presence and severity were not related to rates of insomnia-remission or treatment-resistance following treatment. CONCLUSIONS CBT-i is an effective treatment in the presence of comorbid OSA. This information offers support for the suggestion that patients with comorbid insomnia and OSA should be treated with CBT-i prior to the treatment of the OSA.

The impact of online therapeutic feedback on outcome measures in Internet-CBTI for adolescents with insomnia. Sleep Med 2016; 29:68-75.

Abstract
BACKGROUND Guided Internet cognitive behavioral therapy for insomnia (CBTI) offers an effective treatment for adolescents, but little is known about the active ingredients of therapeutic feedback on outcomes. OBJECTIVE This study aims to identify which factors can be distinguished in written therapeutic feedback in Internet CBTI, and examine whether these factors and participation in a chat session contribute to sleep outcomes. METHODS Internet CBTI was applied to 57 adolescents (mean age 15.43 years, SD 1.74, 82.5% girls). Symptoms of insomnia and chronic sleep reduction, and total sleep time, time in bed, and sleep efficiency from seven day sleep logs were measured at baseline, post-treatment, and at two month follow-up. With a coding instrument developed for this study, two independent researchers coded transcripts of the written therapeutic feedback of the Internet CBTI sessions with an event sampling method. RESULTS Principal component analysis of the initial 17 items from the coding instrument yielded four distinct factors of therapeutic feedback, of which only Sleep expertise seemed to contribute to improvements after Internet CBTI. The other factors, indicating forms of encouragement, and participation in a chat session seemed counterproductive. CONCLUSIONS This first longitudinal study into effects of therapeutic feedback in adolescent Internet CBTI indicated that emphasizing knowledge about sleep might contribute to insomnia improvement. The structured nature of the preprogrammed treatment content, delay of therapeutic feedback due to standardized timing, and unintentional reinforcement of undesirable behavior by giving attention to failures might explain the negative results of encouraging behavior. Further research to identify effective therapeutic factors in Internet therapy is warranted.

Abstract
STUDY OBJECTIVES This paper describes CBT-I Coach, a patient-facing smartphone app designed to enhance cognitive behavioral therapy for insomnia (CBT-I). It presents findings of two surveys of U.S. Department of Veterans Affairs (VA) CBT-I trained clinicians regarding their perceptions of CBT-I Coach before it was released (n = 138) and use of it two years after it was released (n = 176). METHODS VA-trained CBT-I clinicians completed web-based surveys before and two years after CBT-I Coach was publicly released. RESULTS Prior to CBT-I Coach release, clinicians reported that it was moderately to very likely that the app could improve care and a majority (87.0%) intended to use it if it were available. Intention to use the app was predicted by smartphone ownership (β = 0.116, p < 0.05) and perceptions of relative advantage to existing CBT-I practices (β = 0.286, p < 0.01), compatibility with their own needs and values (β = 0.307, p < 0.01), and expectations about the complexity of the app (β = 0.245, p < 0.05). Two years after CBT-I Coach became available, 59.9% of participants reported using it with patients and had favorable impressions of its impact on homework adherence and outcomes. CONCLUSIONS Findings suggest that before release, CBT-I Coach was perceived to have potential to enhance CBT-I and address common adherence issues and clinicians would use it. These results are reinforced by findings two years after it was released suggesting robust uptake and favorable perceptions of its value.

Abstract
Insomnia is one of the most common complaints of US armed service members. Diagnosis and treatment of insomnia in active duty and veteran populations are often complicated by comorbid disorders experienced by military personnel, such as post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). Cognitive behavioral therapy for insomnia (CBTi), pharmacologic interventions, and alternative therapies are discussed as relevant to their applications within military populations. Future directions in research are suggested.

Abstract
BACKGROUND Poor sleep, including insomnia, is common among patients with heart failure (HF). However, little is known about the efficacy of interventions for insomnia in this population. Prior to developing interventions, there is a need for better understanding of patient perceptions about insomnia and its treatment. OBJECTIVES To evaluate HF patients' perceptions about 1) insomnia and its consequences; 2) predisposing, precipitating, and perpetuating factors for insomnia; 3) self-management strategies and treatments for insomnia; and 4) preferences for insomnia treatment. METHODS The study, guided by the "3 P" model of insomnia, employed a parallel convergent mixed methods design in which we obtained qualitative data through focus groups and quantitative data through questionnaires (sleep quality, insomnia severity, dysfunctional beliefs and attitudes about sleep; sleep-related daytime symptoms and functional performance). Content analysis was used to evaluate themes arising from the focus group data, and descriptive statistics were used to analyze the quantitative data. The results of both forms of data collection were compared and synthesized. RESULTS HF patients perceived insomnia as having a negative impact on daytime function and comorbid health problems, pain, nocturia, and psychological factors as perpetuating factors. They viewed use of hypnotic medications as often necessary but disliked negative daytime side effects. They used a variety of strategies to manage their insomnia, but generally did not mention their sleep concerns to physicians whom they perceived as not interested in sleep. CONCLUSIONS HF patients believe insomnia is important and multi-factorial. Behavioral treatments, such as cognitive behavioral therapy, for insomnia may be efficacious in modifying perpetuating factors and likely to be acceptable to patients.
