Effects of cognitive behavioral therapy for insomnia and armodafinil on quality of life in cancer survivors: a randomized placebo-controlled trial

Sleep and Cancer

Background/Objectives: Sleep issues are common in the general population, and these problems occur even more frequently for people with cancer. Sleep problems may pre-exist a patient's cancer diagnosis, and there is a growing interest in understanding the impact of sleep on cancer development and progression. Sleep disorders may impact cancer through altered metabolism, impacts on immune response, and alterations in hormones and gene expression. Sleep disorders may also arise after, or be aggravated by, an individual's cancer and cancer treatment. Treating a person with cancer's sleep disorder may help improve their healing, mental health, cognition, and overall resilience. Methods: Studies examining a variety of aspects of the relationship between sleep and cancer were found by searching the National Library of Medicine and characterized by their specific information provided on the relationship between sleep and cancer. Results: This review article summarizes our current understanding of the complex inter-relationship between sleep and cancer, the underlying mechanisms that create these connections, and the methods and impact of treating sleep issues in cancer patients. The article also outlines an approach to sleep complaints for clinicians caring for patients with cancer. Conclusions: Significant research is still needed to understand the full relationship between sleep disorders and cancer. The impact of sleep issues on cancer and of cancer on sleep appears to be specific to the tissue and the molecular type of cancer. The treatment of sleep disorders is multimodal, and offers a promising avenue to improve the health and quality of life of cancer patients.

Health-related quality of life and mental health outcomes among cancer survivors in an insomnia intervention: a randomized controlled trial

BACKGROUND

While brief behavioral therapy for insomnia (BBTI) has shown promising results in improving sleep outcomes, its effects on health-related quality of life (HRQOL) and mental health among cancer survivors have been understudied.

PURPOSE

To evaluate the effect of BBTI on HRQOL and mental health outcomes among cancer survivors, relative to an attention control group receiving a healthy eating program (HEP), over periods from baseline to 12 months and from 3 to 12 months.

METHODS

A sample of 132 cancer survivors with insomnia symptoms (Mage: 63.7 ± 10 years; 55.3% female) was assessed at baseline, with the final analytical sample of 121 (BBTI = 62, HEP = 59). Self-reported HRQOL, mood disturbance, depression, and anxiety at baseline, 3 months, and 12 months were examined. A multivariate linear model using least squares means evaluated within- and between-group differences.

RESULTS

No significant differences in outcome variables were found between the randomized groups at any time point. Both groups showed significant improvements in total HRQOL, mood disturbance, and anxiety symptoms from baseline to 12 months. Only the BBTI group demonstrated a significant reduction in depressive symptoms within the group, an effect not observed in the HEP group. The most noticeable changes occurred within the first 3 months, with no statistically significant differences from 3 to 12 months within or between groups.

CONCLUSION

While both randomized groups showed improvements in total HRQOL, mood, and anxiety symptoms, only BBTI produced significant within-group improvements in depressive symptoms over 12 months.

Randomized Controlled Trial of Virtually Delivered Cognitive Behavioral Therapy for Insomnia to Address Perceived Cancer-Related Cognitive Impairment in Cancer Survivors

PURPOSE

Comorbid insomnia and cancer-related cognitive impairment (CRCI) are experienced by up to 26% of individuals diagnosed with cancer. This study examined the efficacy and durability of cognitive behavioral therapy for insomnia (CBT-I) on perceived CRCI in cancer survivors.

METHODS

Atlantic Canadian cancer survivors with insomnia and CRCI were randomly assigned to receive seven weekly virtual CBT-I sessions (n = 63) or placed in a waitlist control group (n = 69) to receive treatment after the waiting period. Participants completed assessments at baseline, 1 month (mid-treatment), and 2 months (post-treatment). Age- and education-adjusted mixed-effects models using intention-to-treat principles assessed change at post-treatment. Data from both groups were then pooled to assess the durability of effects at 3 and 6 months. A mediation analysis examined whether change in insomnia symptoms mediated the effect of CBT-I on cognitive outcomes.

RESULTS

The mean age of the sample was 60 years, 77% were women, and breast cancer was the most common diagnosis (41%). The treatment group reported an 11.35-point reduction in insomnia severity, compared with a 2.67-point reduction in the waitlist control group (P < .001). The treatment group had a greater overall improvement than the waitlist control on perceived cognitive impairment (P < .001; d = 0.75), cognitive abilities (P < .001; d = 0.92), and impact on quality of life (P < .001; d = 1.01). These improvements were maintained at follow-up. Change in insomnia symptoms fully mediated the effect of CBT-I on subjective cognitive outcomes.

CONCLUSION

Treating insomnia with CBT-I produces clinically meaningful and durable improvements in CRCI. There is an urgent need increase access to evidence-based treatment for insomnia in cancer centers and the community.

Application and Mechanisms of Internet-Based Cognitive Behavioral Therapy (iCBT) in Improving Psychological State in Cancer Patients

This review article is an overview of the effectiveness of internet-based cognitive behavioral therapy (iCBT) in Improving Psychological State in Cancer Patients. iCBT's effectiveness has been investigated in treating and managing conditions like depression, psychiatric disorders, generalized anxiety disorder (GAD), panic disorder, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), adjustment disorder, bipolar disorder, chronic pain, and phobias. iCBT's role in the treatment of medical conditions such as diabetes mellitus with comorbid psychiatric illnesses was also explored. We conducted a thorough literature search using PubMed, Embase, Google Scholar, and Wanfang with no restrictions on the date. iCBT's role in treating and controlling psychiatric illnesses in cancer patients has been established in the literature. Development and popularization of iCBT, treament forms of iCBT, platforms for iCBT, application of iCBT, strategies and efficacy of iCBT for insomnia in cancer patients, current status of iCBT application, and genetic researches on iCBT for anxiety disorders were all reviewed and discussed in this review. From the data compiled, we conclude that iCBT is useful in treating or improving psychological state in cancer patients.

The Effects of Cognitive Behavioral Therapy for Insomnia among College Students with Irritable Bowel Syndrome: A Randomized Controlled Trial

The aim of the study was to develop and evaluate cognitive behavioral therapy for insomnia (CBT-I) among college students with irritable bowel syndrome (IBS). We randomly assigned 60 college students with IBS comorbid insomnia to the experimental group who received CBT-I for 90 min once a week for 4 weeks and the control (non-CBT-I) group. Participants completed self-report measures of insomnia severity, pre-sleep arousal, sleep-related dysfunctional cognitions, maladaptive sleep habits, IBS symptom severity and IBS quality of life (QOL) at baseline, after intervention, and at 3-month follow-up. Sleep pattern, GI symptoms during sleep and Interleukin-6 (IL-6) and C-Reaction Protein (CRP) were measured at baseline and after intervention. The experimental group showed significant decreases in insomnia severity, sleep onset latency, total time in bed, pre-sleep arousal, GI symptoms during sleep, sleep-related dysfunctional cognitions, maladaptive sleep habits, and IBS symptom severity, compared with the control group. This group also showed significant increases in sleep efficiency and IBS QOL compared with the control group. No significant differences were observed between the levels of IL-6 and CRP of both groups. CBT-I for college students with comorbid IBS and insomnia was effective in reducing insomnia, IBS symptom severity, and IBS QOL.

Insomnia

Insomnia is highly prevalent in clinical practice, occurring in up to 50% of primary care patients. Insomnia can present independently or alongside other medical conditions or mental health disorders and is a risk factor for the development and exacerbation of these other disorders if not treated. In 2016, the American College of Physicians recommended that insomnia be specifically targeted for treatment. The recommended first-line treatment for insomnia, whether the underlying cause has been identified or not, is cognitive behavioural therapy for insomnia (CBT-I). Currently, there is no global consensus regarding which pharmacological treatment has the best efficacy or risk-benefit ratio. Both CBT-I and pharmacological intervention are thought to have similar acute effects, but only CBT-I has shown durable long-term effects after treatment discontinuation. Administering a combined treatment of CBT-I and medication could decrease the latency to treatment response, but might diminish the durability of the positive treatment effects of CBT-I.

Cognitive behavioural therapy for insomnia in people with cancer

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To assess the effects of cognitive behavioural therapy (CBT) for insomnia in people with cancer. 

We will evaluate the effects at different periods of the cancer treatment (before, during, or after treatment), and analyse the effects of CBT on quality of life.

The relationship between sleep hygiene, mood, and insomnia symptoms in men with prostate cancer

PURPOSE

Insomnia symptoms are commonly experienced by men after prostate cancer (PCa) treatment. Here we explored how sleep hygiene behaviours and psychological symptoms are associated with insomnia symptoms in PCa patients.

METHODS

An online survey was posted on social media and sent to mailing lists of PCa and general cancer organisations. The survey collected information on demographic, sleep hygiene, and psychological symptoms using validated questionnaires.

RESULTS

Data from 142 participants were compared based on the absence (age = 68.3 ± 8.9 years) and presence (age = 66.6 ± 9.0 years) of insomnia symptoms. Participants with insomnia symptoms had significantly higher levels of anxiety, depression, fatigue, and sleepiness as well as poorer sleep hygiene than those without insomnia symptoms. Control variables (age, number of comorbidities, and BMI) accounted for 11.9% of the variance in insomnia symptoms. Including treatment history contributed to an additional 1.6% of the variance in insomnia symptoms. Adding sleepiness, fatigue, anxiety, and depressive symptoms to the model explained an additional 44.6% of the variance in insomnia symptoms. Furthermore, including the sleep hygiene item 'I think, plan, or worry when I am in bed' and 'I sleep in an uncomfortable bedroom' explained an additional 3.6% of the variance in insomnia symptoms.

CONCLUSIONS

Poor sleep hygiene, fatigue, sleepiness, anxiety, and depressive symptoms were all associated with worse insomnia symptoms in PCa patients. Improving sleep hygiene and treating psychological conditions may potentially help prevent and/or alleviate insomnia symptoms in PCa patients.

Impacts of Cognitive Behavioral Therapy for Insomnia and Pain on Sleep in Women with Gynecologic Malignancies: A Randomized Controlled Trial

Insomnia is an adverse cancer outcome impacting mood, pain, quality of life, and mortality in cancer patients. Cognitive Behavioral Therapy (CBT) is an evidence-based treatment for diverse psychophysiological disorders, including pain and insomnia. Primarily studied in breast cancer, there is limited research on CBT within gynecology oncology. This study examined CBT effects on subjective and behavioral sleep outcomes: Sleep Efficiency (SE), Sleep Quality (SQ), Total Wake Time (TWT), Sleep Onset Latency (SOL), and Wake After Sleep Onset (WASO). Thirty-five women with insomnia status/post-surgery for gynecologic cancer were randomized to CBT for insomnia and pain (CBTi.p., N = 18) or Psychoeducation (N = 17). Sleep was assessed via sleep diaries and wrist-worn actigraphy at baseline (T1), post-intervention (T2), and two-month follow-up (T3). Intent-to-treat analyses utilizing mixed linear modeling examined longitudinal group differences on sleep controlling for age and advanced cancer. All participants demonstrated improved (1) subjective SE (0.5, p < .01), SOL (-1.2, p < .01), TWT (-1.2, p < .01), and (2) behavioral SE (0.1, p = .02), TWT (-1.2, p = .03), WASO (-0.8, p < .01) across time. Group-level time trends were indicative of higher subjective SE (6.8, p = .02), lower TWT (-40.3, p = .01), and lower SOL (-13.0, p = .05) in CBTi.p. compared to Psychoeducation. Supplemental analyses examining clinical significance and acute treatment effects demonstrated clinical improvements in SE (T1), TWT (T2, T3), and SOL (T3). Remaining effects were not significant. Despite lacking power to detect interaction effects, CBTi.p. clinically improved sleep in women with gynecologic cancers and insomnia during the active treatment phase. Future research will focus on developing larger trials within underserved populations.

Sleep Disorders in Cancer-A Systematic Review

INTRODUCTION

Sleep disorders, especially insomnia, are very common in different kinds of cancers, but their prevalence and incidence are not well-known. Disturbed sleep in cancer is caused by different reasons and usually appears as a comorbid disorder to different somatic and psychiatric diagnoses, psychological disturbances and treatment methods. There can be many different predictors for sleep disturbances in these vulnerable groups, such as pre-existing sleep disorders, caused by the mental status in cancer or as side effect of the cancer treatment.

METHODS

A systematic literature review of 8073 studies was conducted on the topic of sleep and sleep disorders in cancer patients. The articles were identified though PubMed, PsycInfo and Web of Knowledge, and a total number of 89 publications were qualified for analysis.

RESULTS

The identified eighty-nine studies were analyzed on the topic of sleep and sleep disorders in cancer, twenty-six studies on sleep and fatigue in cancer and sixty-one studies on the topic of sleep disorders in cancer. The prevalence of sleep disturbences and/or sleep disorders in cancer was up to 95%.

DISCUSSION

Sleep disturbances and sleep disorders (such as insomnia, OSAS, narcolepsy and RLS; REM-SBD) in cancer patients can be associated with different conditions. Side effects of cancer treatment and cancer-related psychological dysfunctions can be instigated by sleep disturbances and sleep disorders in these patients, especially insomnia and OSAS are common. An evidence-based treatment is necessary for concomitant mental and/or physical states.

Recent trends in the management of depression in persons with cancer

PURPOSE OF REVIEW

Depression is a prevalent comorbidity in cancer that significantly increases the risk for numerous negative health outcomes. This review updates the current evidence base for management of depression in cancer, highlighting new research directions based on the inflammatory hypothesis of depression.

RECENT FINDINGS

Research on pharmacotherapy and psychotherapy for depression in cancer has shown mixed efficacy partly because of methodological issues arising from the phenomenology of depression in cancer. After decades of stagnancy, more recent high-quality clinical trials are beginning to provide an evidence base to guide treatment. Inflammatory cytokine-associated depression is a subtype of depression that may have particular relevance in cancer, opening new avenues to explore therapeutic targets and biobehavioral impacts of interventions, which may improve cancer outcomes.

SUMMARY

The continuum of severity in cancer-related depression is important to consider in management approaches. Choice of treatment should be personalized to the patient and their symptom profile as there is currently insufficient evidence to recommend any particular medication or psychotherapy over another. Psychological interventions should be considered first line for mild-to-moderate depression, and pharmacological treatment added for more severe depression, which can be optimally delivered within a collaborative care model.

The effect of a group cognitive behavioral therapy on the quality of life and emotional disturbance of women with breast cancer

PURPOSE

While the rate of survival has increased in the past decade, the diagnosis of breast cancer is an extremely stressful experience for patients and it is associated with the manifestation of several psychological problems. To examine the effect of a group cognitive behavioral therapy (CBT) on the quality of life and emotional disturbance of women with breast cancer.

METHODS

The study was a randomized controlled clinical trial. Samples were 48 women who had been diagnosed with breast cancer and had undergone mastectomy and chemotherapy. Study variables were measured before and after the intervention and 1 month after the end of the intervention as a follow-up. Controls received nothing and were just followed-up. Repeated measure ANOVAs were used to compare the effectiveness of the intervention on the study variables.

RESULTS

The results of 32 women were analyzed. The increase in quality of life scores was significantly higher in the intervention group compared to the control group (P < 0.05). There were also significantly lower changes in the depression, anxiety, and stress scores of the intervention group (P < 0.05). However, the changes in the score of death anxiety were not significantly lower in the intervention group in comparison to controls (P > 0.05).

CONCLUSION

Group cognitive behavioral therapy was effective in the improvement of quality of life and decreases some aspects of emotional disturbance. Findings of this study suggest that women with breast cancer can benefit from group CBT. Yet, some aspects of the mental health of these women may need more attention and individualized methods.

Efficacy of cognitive behavioral therapy for insomnia in breast cancer: A meta-analysis

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.

The Feasibility and Effects of Qigong Intervention (Mind-Body Exercise) in Cancer Patients With Insomnia: A Pilot Qualitative Study

Background:

Up to 80% of cancer patients experience insomnia that significantly affects their quality of life. This pilot qualitative study investigated the feasibility and effects of a 3-week Qigong (mind-body exercise) intervention with a 1-week follow-up in cancer patients experiencing insomnia.

Methods:

Cancer patients with insomnia who had completed radiotherapy or chemotherapy treatment and/or were at least 8 weeks post-cancer-related surgery were recruited. Primary outcomes were feasibility outcomes, which included recruitment, retention, attendance, completion of assessment, adverse events and participant feedback via a questionnaire and focus group/individual interview. Secondary outcomes on insomnia severity and sleep quality were measured using the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI) at baseline, mid, post-intervention and follow-up.

Results:

Seven participants were recruited and two withdrew from the study. The participant retention rate was 71.4% with an overall attendance rate of more than 84% and participants were able to complete all required assessments. An adverse event relating to the worsening of existing musculoskeletal condition was reported. Qualitative analysis of participant feedback identified 4 emerging themes: (1) experience from Qigong intervention; (2) class preferences; (3) barriers to participation; and (4) recommendation for improvement. Participants reported increased relaxation, improved sleep and energy level, better upper body flexibility and reduced stress. Both ISI and PSQI scores improved significantly (P < .05).

Conclusion:

This study demonstrated that it is feasible to employ the current clinical trial design using Qigong intervention on insomnia in cancer patients. Preliminary data suggest that the intervention may improve sleep outcomes, however, these findings need to be confirmed by future robust randomized controlled trials.

Living with persistent insomnia after cancer: A qualitative analysis of impact and management

OBJECTIVES

To conduct a qualitative exploration of the lived experience of insomnia disorder and its management amongst a sample of mixed-diagnoses cancer survivors.

METHODS

Twenty-seven cancer survivors with persistent insomnia were recruited to this qualitative study following completion of treatment for breast (12), prostate (7), colorectal (7), and gynaecological (1) cancers. Eleven males and 16 females (mean age 62 years), who met DSM-5 criteria for insomnia disorder, contributed to one of four focus group discussions, designed to explore the lived experience of persistent insomnia and its management within cancer care services.

RESULTS

Poor sleep was a persistently troubling complaint for participants, long after the completion of active cancer treatment. The impact of insomnia was significant for all participants, with six key domains emerging as those most affected: temperament, sociability, physical well-being, cognitive functioning, relationships, and psychological well-being. In terms of insomnia management, participants frequently resorted to unfruitful self-management strategies, due to the lack of professional insomnia expertise within cancer care settings. Three main themes emerged in relation to insomnia management: self-management, seeking professional intervention, and a lack of focus on sleep. A lack of clinician understanding of the importance of sleep health and the poor availability of evidence-based insomnia interventions, such as cognitive behavioural therapy for insomnia (CBT-i), were highlighted as important gaps in cancer care.

CONCLUSIONS

Insomnia was found to have a detrimental and pervasive impact on cancer survivors' quality of life, which persisted long into survivorship. There is an absence of professional attention to sleep throughout the cancer care trajectory, contributing to its prevalence, persistence, and impact. In order to break this cycle, sleep health should be integrated as a key aspect of cancer treatment and rehabilitation, much like maintaining a healthy diet and appropriate levels of physical activity.

Pharmacokinetic and pharmacodynamic of the cognitive enhancer modafinil: Relevant clinical and forensic aspects

Modafinil is a nonamphetamine nootropic drug with an increasingly therapeutic interest due to its different sites of action and behavioral effects in comparison to cocaine or amphetamine. A review of modafinil (and of its prodrug adrafinil and its R-enantiomer armodafinil) chemical, pharmacokinetic, pharmacodynamic, toxicological, clinical and forensic aspects was performed, aiming to better understand possible health problems associated to its unconscious and unruled use. Modafinil is a racemate metabolized mainly in the liver into its inactive acid and sulfone metabolites, which undergo primarily renal excretion. Although not fully clarified, major effects seem to be associated to inhibition of dopamine reuptake and modulation of several other neurochemical pathways, namely noradrenergic, serotoninergic, orexinergic, histaminergic, glutamatergic and GABAergic. Due its wake-promoting effects, modafinil is used for the treatment of daily sleepiness associated to narcolepsy, obstructive sleep apnea and shift work sleep disorder. Its psychotropic and cognitive effects are also attractive in several other pathologies and conditions that affect sleep structure, induce fatigue and lethargy, and impair cognitive abilities. Additionally, in health subjects, including students, modafinil is being used off-label to overcome sleepiness, increase concentration and improve cognitive potential. The most common adverse effects associated to modafinil intake are headache, insomnia, anxiety, diarrhea, dry mouth and raise in blood pressure and heart rate. Infrequently, severe dermatologic effects in children, including maculopapular and morbilliform rash, erythema multiforme and Stevens-Johnson Syndrome have been reported. Intoxication and dependence associated to modafinil are uncommon. Further research on effects and health implications of modafinil and its analogs is steel needed to create evidence-based policies.

Nurse-Delivered Brief Behavioral Treatment for Insomnia in Lung Cancer Survivors: A Pilot RCT

Objective/Background: Insomnia occurs in 50 to 80% of lung cancer survivors. Cognitive behavioral therapy is the standard treatment for insomnia (CBTI); however, treatment length and lack of psychologists trained in CBTI limits access. Brief Behavioral Treatment for Insomnia (BBTI), a nurse-delivered modified CBTI, is proposed. This feasibility pilot study sought to compare the BBTI intervention to attention control Healthy Eating Program (HEP) for insomnia in lung cancer survivors. Participants: The participants comprised adults, 21 years of age or older with insomnia and stage I/II non-small cell lung cancer, more than 6 weeks from surgery and living in Western NY. Methods: Participants (n = 40) were randomly assigned to an experimental (BBTI) or attention control condition (Healthy Eating Program). Thirty participants completed the study. Results: Participants were 66 years of age (± 7.6; range 53-82), 40% (n = 16) male, 87.5% (n = 35) Caucasian, 50% (n = 20) married, BMI 27.7 (± 5.8), and 12% (n = 5) never smokers. Baseline sleep diary sleep efficiency, ISI and other baseline covariates were balanced between the groups. Sleep efficiency improved ≥85% in BBTI group (p = .02), but not in HEP control group (p = 1.00). Mean ISI for BBTI and attention control were 6.40 ± 4.98 and 14.10 ± 4.48 (p = .001) respectively. In addition, BBTI group mean total FACT-L score improved by 6.66 points from baseline while HEP group score worsened (p = .049). Conclusions: BBTI is a practical, evidence-based, clinically relevant intervention that improved sleep and quality of life in lung cancer survivors with insomnia. Additional research to evaluate efficacy, duration, and implementation strategies are essential.

Psychological support for patients with cancer: evidence review and suggestions for future directions

PURPOSE OF REVIEW

Psychological distress and mental health comorbidity are common in cancer. Various therapeutic frameworks have been used for interventions to improve psychological wellbeing and quality of life in cancer patients with mixed results. This article reviews contributions to that literature published since January 2017.

RECENT FINDINGS

The majority of new psychological intervention research in cancer has used cognitive behavioural therapy (CBT) or mindfulness-based interventions. CBT has been considered a gold-standard intervention and recent evidence justifies continuation of this. Recent reviews call into question the validity of evidence for mindfulness-based interventions. A smaller number of trials using acceptance and commitment therapy, meta-cognitive therapy, dignity therapy and coaching have emerged, and whereas findings are promising, additional fully powered trials are required. Weaker evidence exists for counselling, support-based and narrative therapy interventions.

SUMMARY

Efficacious, timely and acceptable psychological interventions are a necessary component of comprehensive cancer care. There is some way to go before the evidence conclusively points towards which interventions work for which cancer groups and for which specific outcomes. Methodological limitations must be addressed in future trials; at the forefront remains the need for fully powered, head-to-head comparison trials.

Cognitive Behavioral Therapy for Insomnia Reduces Depression in Cancer Survivors

STUDY OBJECTIVES

The current archival analyses examine the direct and indirect effects of cognitive behavioral therapy for insomnia (CBT-I) on depression in cancer survivors.

METHODS

We report on 67 cancer survivors from a 2 × 2 randomized controlled trial of CBT-I and armodafinil for insomnia, after collapsing across the noneffective study medication conditions (armodafinil/placebo) to create CBT-I (yes/no). Depression and insomnia were assessed before, during the 7-week CBT-I intervention, at postintervention, and 3 months later by the Patient Health Questionnaire and the Insomnia Severity Index, respectively.

RESULTS

Mean depression at baseline for all participants was 6.44 (standard error = 0.41, range 0-15). Paired t tests showed that depression improved from baseline to postintervention by 48% (P < .001) in the CBT-I group versus 15% (P = .016) in the non-CBT-I group. Analysis of covariance controlling for baseline found that participants receiving CBT-I had significantly less depression at postintervention (effect size = -0.62; P = .001), compared to those who did not receive CBT-I. These benefits were maintained at the 3-month follow-up. Spearman rank correlations showed that changes in insomnia severity from baseline to postintervention were significantly correlated with concurrent changes in depression (r = .73; P < .001). Path analysis revealed that improvement in depression was mediated by improvement in insomnia severity (P < .001).

CONCLUSIONS

Our findings provide preliminary support that in cancer survivors, CBT-I reduces depression via improvement in insomnia. Further, this reduction in depression remained stable 3 months after completing CBT-I. This suggests that a CBT-I intervention has a meaningful effect on depression.

Effect of Digital Cognitive Behavioral Therapy for Insomnia on Health, Psychological Well-being, and Sleep-Related Quality of Life: A Randomized Clinical Trial

Importance

Digital cognitive behavioral therapy (dCBT) is a scalable and effective intervention for treating insomnia. Most people with insomnia, however, seek help because of the daytime consequences of poor sleep, which adversely affects quality of life.

Objectives

To investigate the effect of dCBT for insomnia on functional health, psychological well-being, and sleep-related quality of life and to determine whether a reduction in insomnia symptoms was a mediating factor.

Design, Setting, and Participants

This online, 2-arm, parallel-group randomized trial comparing dCBT for insomnia with sleep hygiene education (SHE) evaluated 1711 participants with self-reported symptoms of insomnia. Participants were recruited between December 1, 2015, and December 1, 2016, and dCBT was delivered using web and/or mobile channels plus treatment as usual; SHE comprised a website and a downloadable booklet plus treatment as usual. Online assessments took place at 0 (baseline), 4 (midtreatment), 8 (posttreatment), and 24 (follow-up) weeks. Programs were completed within 12 weeks after inclusion.

Main Outcomes and Measures

Primary outcomes were scores on self-reported measures of functional health (Patient-Reported Outcomes Measurement Information System: Global Health Scale; range, 10-50; higher scores indicate better health); psychological well-being (Warwick-Edinburgh Mental Well-being Scale; range, 14-70; higher scores indicate greater well-being); and sleep-related quality of life (Glasgow Sleep Impact Index; range, 1-100; higher scores indicate greater impairment). Secondary outcomes comprised mood, fatigue, sleepiness, cognitive failures, work productivity, and relationship satisfaction. Insomnia was assessed with the Sleep Condition Indicator (range: 0-32; higher scores indicate better sleep).

Results

Of the 1711 participants included in the intention-to-treat analysis, 1329 (77.7%) were female, mean (SD) age was 48.0 (13.8) years, and 1558 (91.1%) were white. Use of dCBT was associated with a small improvement in functional health compared with SHE (adjusted difference [95% CI] at week 4, 0.90 [0.40-1.40]; week 8, 1.76 [1.24-2.28]; week 24, 1.76 [1.22-2.30]) and psychological well-being (adjusted difference [95% CI] at week 4, 1.04 [0.28-1.80]; week 8, 2.68 [1.89-3.47]; week 24, 2.95 [2.13-3.76]), and with a large improvement in sleep-related quality of life (at week 4, -8.76 [-11.83 to -5.69]; week 8, -17.60 [-20.81 to -14.39]; week 24, -18.72 [-22.04 to -15.41]) (all P < .01). A large improvement in insomnia mediated these outcomes (range mediated, 45.5%-84.0%).

Conclusions and Relevance

Use of dCBT is effective in improving functional health, psychological well-being, and sleep-related quality of life in people reporting insomnia symptoms. A reduction in insomnia symptoms mediates these improvements. These results confirm that dCBT improves both daytime and nighttime aspects of insomnia, strengthening existing recommendations of CBT as the treatment of choice for insomnia.

New Method for Insomnia Mongolian Mind-Body Interactive Psychotherapy in the Assessment of Chronic Insomnia: A Retrospective Study

INTRODUCTION

Insomnia is a common clinical complaint, and if not addressed it can increase the risk of developing other underlying diseases such as hypertension, depression and anxiety. The use of Mongolian mind-body interactive therapy as a comprehensive psychotherapeutic approach in chronic insomnia has been shown in this retrospective study.

METHODS

Subjects who had suffered insomnia for more than 1 month participated in the Mongolian mind-body interactive psychotherapy program between June 2012 and February 2014. They were interviewed by telephone at least 10 months before participating in the program. Their sleep was assessed using the Athens insomnia scale. Descriptive statistics, ANOVA and regression analysis were used for data analysis by SPSS software.

RESULTS

Mongolian mind-body interactive psychotherapy significantly improved sleeping conditions. In ANOVA analysis, both short- and long-term outcomes were significantly affected by the treatment period. Patients who previously took medication and pre-treatment sleeping condition (ASI score) had a significant influence on long-term outcomes, as well as treatment time related to the duration of insomnia.

CONCLUSION

Mongolian mind-body interactive psychotherapy is a new method for insomnia, and narrative therapy and hypnotic methods together improve the sleeping condition, However, a further controlled randomized clinical study is needed to understand the efficacy.
