Social Support, Insomnia, and Adherence to Cognitive Behavioral Therapy for Insomnia After Cancer Treatment

Exploring the differential effects of psychological resilience and social support in mitigating post-traumatic psychiatric symptoms: real-world network analysis of front-line rescuers

BACKGROUND

Although both psychological resilience and social support are widely believed to be effective in alleviating post-traumatic psychiatric symptoms in individuals with traumatic events, there has been a lack of comparative analysis of their intervention effects on different post-traumatic psychiatric symptoms. Furthermore, previous studies have mostly failed to control for potential confounding effects caused by different traumatic events.

AIMS

We used the novel network analysis approach to examine the differential moderating effects of psychological resilience and social support on post-traumatic psychiatric symptoms, controlling for the confounding effects of traumatic events.

METHOD

We recruited 264 front-line rescuers who experienced the same traumatic event. Quantified edge weights and bridge expected influence (BEI) were applied to compare the alleviating effects of psychological resilience and social support.

RESULTS

Our study revealed distinct correlations in a sample of front-line rescuers: social support negatively correlates more with psychosomatic symptoms, notably fatigue in depressive networks and sleep disturbance in post-traumatic stress disorder (PTSD) networks, whereas psychological resilience shows fewer such correlations. Quantitative analysis using BEI indicated that psychological resilience more effectively suppresses depressive and anxiety symptom networks, whereas social support more significantly inhibits PTSD symptom networks.

CONCLUSIONS

The current study represents the first attempt to examine the differential effects of psychological resilience and social support on post-traumatic outcomes in real-world emergency rescuers, controlling for the confounding effect of traumatic events. Our results can act as the theoretical reference for future precise and efficient post-trauma psychological interventions.

Factors associated with sleep quality in patients undergoing cardiac surgery: A longitudinal study

BACKGROUND

Poor sleep quality is associated with multiple factors in cardiac surgery patients.

AIM

To examine the trajectory of sleep quality and its associated factors over 3 months in Taiwanese patients undergoing cardiac surgery.

STUDY DESIGN

A longitudinal study. This study enrolled 95 patients undergoing cardiac surgery in northern Taiwan. Sleep quality was measured using the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale before surgery, at discharge, and at 1 month and 3 months postsurgery.

RESULTS

The majority of participants reported poor sleep quality before cardiac surgery (76.8%) and at discharge (81.6%), and they showed significant improvements in sleep quality at 1 month (B = -0.93, p = .023) and 3 months postsurgery (B = -1.50, p < .001). Significant daytime sleepiness was reported by 25.3% of patients before cardiac surgery, and this proportion significantly decreased at 3 months postsurgery (B = -2.59, p < .001). The significant predictors of sleep quality in cardiac surgery patients were symptom distress, sleep medications, occupation, left ventricular ejection fraction, ACE-I drugs and potassium ions, which explained 53.7% of the total variance in sleep quality. Having a nap habit was an independent predictor of daytime sleepiness in cardiac surgery patients, which could explain 3.7% of the total variation.

CONCLUSION

Poor sleep quality was common in patients undergoing cardiac surgery and was associated with multiple factors, including symptom distress, cardiac function, medications, and psychosocial and environmental factors.

RELEVANCE TO CLINICAL PRACTICE

Poor sleep quality was observed in cardiac surgical patients before surgery and at discharge postsurgery. Patient education on symptom management, medication adherence and sleep hygiene are suggested to improve sleep quality in patients undergoing cardiac surgery.

Factors associated with the sleep disturbances of people with breast cancer during chemotherapy in China: A cross-sectional study

AIM

The aim of the study was to investigate the incidence of sleep disturbance and its relationship with anxiety and depression symptoms, social support and hope in breast cancer patients in China during chemotherapy.

DESIGN

A single-centre cross-sectional study.

METHODS

A total of 329 breast cancer patients were selected via convenience sampling method before they began chemotherapy (n = 115), before the 5th week of chemotherapy (n = 117) or 1 month after chemotherapy ended (n = 97) and administered paper-and-pencil questionnaires to evaluate sleep quality, depression and anxiety symptoms, social support and hope. Risk factors significantly associated with sleep disturbance during bivariate were incorporated in the multivariate analysis. Bivariate analyses showed that age, menopausal status, depression and anxiety symptoms, emotional/informational support, tangible support, affectionate support, positive social interaction and total support were predictors of sleep disturbance.

RESULTS

Sleep disturbance was prevalent in breast cancer patients before (27.0%), during (32.5%) and after (39.2%) chemotherapy, with 37.4%, 41.9% and 52.6% of participants, respectively, reporting sleeping below the recommended 7 h. Only 8.6%-15.5% of patients reported taking sedative-hypnotic drugs during the chemotherapy. Multivariate analyses found that participants reporting clinically significant anxiety (HADS > 8) were 3.5 times more likely to report sleep disturbance (PSQI > 8) than participants without clinically significant anxiety, and each increment in emotional/informational support was associated with a 9.04% reduced risk of sleep disturbance. Moreover, age was an independent predictor of sleep disturbance during multivariate modelling.

Mind-Body Therapies for Sleep Disturbance among Patients with Cancer: A Systematic Review and Meta-analysis

OBJECTIVE

s: To assess whether mind-body therapies (MBTs) are effective for relieving sleep disturbance among patients with cancer.

DESIGN

Systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

Seven English electronic databases were searched from the date of inception to September 2022. All RCTs that included adults (≥18 years) who were treated with mindfulness, yoga, qigong, relaxation, and hypnosis were screened. The outcome was subjective and/or objective sleep disturbance.The revised Cochrane tool (RoB 2.0) was applied to evaluate the risk of bias. The RevMan software was applied to assessed each outcome according different control groups and assessment time points. Subgroup analyses were performed according to different categories of MBTs.

RESULTS

Sixty-eight RCTs (6339 participants) were identified. After requesting for missing data from corresponding authors of included RCTs, 56 studies (5051 participants) were included in the meta-analysis. The meta-analysis showed a significant immediate effect of mindfulness, yoga, relaxation, and hypnosis on subjective sleep disturbance, compared with usual care or wait list control, and the effect of mindfulness lasted at least 6 months. For objective sleep outcomes, we observed significant immediate effects of yoga on wake after sleep onset and of mindfulness on sleep onset latency and total sleep time. Compared with active control interventions, MBTs had no significant effect on sleep disturbance.

CONCLUSIONS

Mindfulness, yoga, relaxation, and hypnosis were effective in sleep disturbance severity reduction among patients with cancer at post-intervention, and the effect of mindfulness lasted at least 6 months. Future MBTs studies should apply both objective and subjective sleep measurement tools.

Recommendations to bolster adherence in cognitive behavioral therapy for insomnia: a self-efficacy approach

The safest and most effective treatment for chronic insomnia is Cognitive Behavioural Therapy for Insomnia (CBT-I). People sometimes struggle to adhere to, or follow the steps, involved in CBT-I because they are challenging (i.e., restricting time in bed to induce sleepiness, getting out of bed when not sleeping). These steps are based on sleep science and research shows that more closely adhering to them relates to better sleep improvements. One way that clinicians can help patients completing CBT-I improve their adherence to the difficult treatment steps is to promote their self-efficacy, or belief that they can effectively complete the treatment steps. Inspired by tried-and-true health promotion techniques rooted in Social Cognitive Theory, this paper describes concrete recommendations that clinicians can use to improve their patients’ self-efficacy when completing CBT-I. These recommendations include suggestions such as setting positive treatment expectations, discussing with patients how to set up for success when completing the treatment steps at home, and how to work with potential barriers to treatment. If clinicians can help boost patients’ self-efficacy, they may be able to carry out the treatment steps of CBT-I more effectively, and ultimately experience more benefits.

Partner Alliance to Enhance Efficacy and Adherence of CBT-I

Cognitive behavioral therapy for insomnia (CBT-I) is now widely recognized as the first-line management strategy for insomnia, both for insomnia in its "pure" form, and when comorbid with a physical or psychological illness. However, there is a definite need to develop and test both alternative and adjunct interventions to CBT-I, before implementing them into routine practice. The aim of this article is to provide a narrative review of the literature with regard to what is known about the influence of partners on sleep, insomnia, and its management.

A moderated serial mediation analysis of the association between HIV stigma and sleep quality in people living with HIV: a cross-sectional study

With the wide use of antiretroviral therapy in people living with HIV (PLWH), the mortality and morbidity rates among this community are dramatically decreasing. However, sleep disorder is still one of the prominent health issues among PLWH, and it lowers their quality of life. Although we already know the potential biological pathway that links poor sleep quality among PLWH, the potential contribution of the psychosocial pathway (e.g., stigma) is far from understood. In this study, we aimed to explore the potential serial mediating effects (HIV stigma-loneliness-depression-sleep quality) and potential moderating effects of perceived social support. We recruited a consecutive sample of 139 participants from voluntary counseling testing (VCT) clinics of Beijing Youan Hospital and participant referrals. Then, we used serial mediation models and moderated serial mediation models to fit our data. We found significant serial mediation effects between three types of HIV stigma (enacted, anticipated, and internalized) and sleep quality via depression and loneliness. Perceived social support also significantly moderated this serial mediation between enacted stigma, internalized stigma, and sleep quality. Our results highlight the potential role of perceived social support in moderating the negative effects of enacted and internalized stigma on sleep quality and identify potential psychosocial pathways.

Treatment Fidelity in a Randomized Controlled Trial of Cognitive Behavioral Therapy for Insomnia in Heart Failure

BACKGROUND

Cognitive behavioral therapy for insomnia (CBT-I) is an efficacious treatment for people with chronic insomnia, including those with heart failure (HF). Treatment fidelity evaluation is needed to ensure study validity and reliability.

OBJECTIVE

The aim of this study was to apply the National Institutes of Health Behavioral Change Consortium framework to ensure adequate treatment fidelity in a randomized controlled trial of CBT-I for people with stable HF.

METHODS

We describe strategies to ensure treatment fidelity in study design, provider training, and treatment delivery. We measured treatment receipt (observation and self-report) and enactment of CBT-I strategies (self-report and actigraphy). We used the Dysfunctional Beliefs and Attitudes About Sleep Scale and the Sleep Disturbance Questionnaire to indicate sleep-related beliefs and cognitions. We computed descriptive statistics for demographic characteristics, treatment receipt, and enactment variables. We compared baseline and post-intervention dichotomous sleep behaviors using the two-sided Wilcoxon rank-sum test. We calculated the root mean square of successive difference in time of sleep onset and midpoint (actigraphy) to indicate day-by-day variability in bed and wake times.

RESULTS

Most participants completed the CBT-I intervention and follow-up assessments and attended each group or make-up session. Most correctly computed their sleep efficiency and completed their homework. Most participants used the sleep tracker and reported using strategies to improve their sleep schedules. There was a significant decrease in actigraph-measured light intensity during the 30 minutes and 1 hour before bedtime between baseline and post-intervention and no statistically significant changes in light intensity after waking or in nap frequency. Most of those who woke during the night got out of bed, consistent with recommendations. There were significant improvements on all of the Dysfunctional Beliefs and Attitudes About Sleep items and total score and all but one item on the Sleep Disturbance Questionnaire.

DISCUSSION

Preserved treatment fidelity may explain the large and sustained effects in people with HF found in our trial. Further research is needed to evaluate CBT-I's effectiveness and implementation strategies among people with HF in real-world clinical settings.

For whom and what outcomes does cognitive-behavioral-therapy work among cancer survivors: a systematic review and meta-analysis

OBJECTIVE

To perform a systematic review and meta-analysis of CBT for individuals diagnosed with cancer across a broad range of outcome domains, i.e., functional health, psychological health, health behaviors, social relational, and general wellness.

METHODS

A comprehensive search of 7 databases, 91 published reviews, and 4 professional websites was performed on August 30th, 2021. English-language clinical trials of CBT for cancer patients/survivors were included. Studies were independently screened, and data were extracted by 2 reviewers, and discrepancies were resolved by consensus among the investigative team. A total of 151 clinical trials (154 articles) published between 1986 and 2021 were included in the analysis.

RESULTS

CBT was overall effective for cancer patients/survivors in the domains of functional health, g = 0.931, p < 0.001, psychological health, g = 0.379, p < 0.001, and general wellness, g = 0.257, p < 0.001, but ineffective in domains of health behaviors, g = 0.792, p > 0.05, and social relational outcomes, g = 0.319, p > 0.05. Additional subgroup and moderator analyses further revealed CBT's differential treatment effect for different within domain outcomes, across different cancer disease stages, and CBT delivery format.

CONCLUSIONS

Findings of the study showed that CBT is an effective treatment for individuals diagnosed with cancer. However, treatment effects differ by important disease- and intervention-related factors, which should be considered when recommending CBT for cancer patients/survivors.

Factors Associated With Healthcare Workers' Insomnia Symptoms and Fatigue in the Fight Against COVID-19, and the Role of Organizational Support

Background: Healthcare workers (HCWs) have been exposed to increased risks of insomnia and fatigue during the COVID-19 pandemic. In this study, we identify important risk factors associated with insomnia symptoms and fatigue among HCWs, and evaluate the effect of organizational support on insomnia and fatigue symptoms. Methods: This is an online cross-sectional survey of HCWs in China administered during the COVID-19 epidemic (from February 27, 2020 to March 12, 2020). We employed the AIS-8 scale for insomnia screening, and a self-reported ten-point scale to evaluate subjects' degrees of fatigue. We also designed a four-point scale to assess the degree of social support provided on an organizational level. Additionally, we conducted logistic regression analysis to identify risk factors. Results: This study included a total of 3,557 participants, 41% of which consisted of non-frontline HCWs and 59% of which was frontline HCWs. Of the non-frontline HCWs, 49% reported insomnia symptoms, and 53.8% reported a moderate to high degree of fatigue. Meanwhile, among the frontline HCWs, the percentages for insomnia and moderate to high fatigue were 63.4% and 72.2%, respectively. Additionally, frontline HCWs and HCWs employed at Centers for Disease Control and Prevention (CDCs) had elevated risks of insomnia and fatigue. However, with increased organizational support, insomnia symptoms decreased among frontline HCWs. Also, organizational support mitigated the positive correlation between daily working hours and degree of fatigue among HCWs. Conclusion: Frontline HCWs and staff in Chinese CDCs have been at a high risk of insomnia symptoms and fatigue during the fight against COVID-19. This study provides evidence for the positive effects of organizational support in relation to insomnia and fatigue among HCWs. This sheds light on government responses to the COVID-19 epidemic for other countries.

The Psychological Pressures of Breast Cancer Patients During the COVID-19 Outbreak in China-A Comparison With Frontline Female Nurses

Objective: During the outbreak of the COVID-19 epidemic in China, breast cancer (BC) patients and healthcare workers faced several challenges, resulting in great psychological stress. We measured the psychological status of BC patients and female nurses and compared the severity within the two groups at the peak time-point of the COVID-19 outbreak. Methods: A total of 207 BC patients and 684 female nurses were recruited from Wuhan. They completed an anonymous questionnaire online using the most popular social media software in China, WeChat. The psychological status of BC patients and of female nurses was measured using the Chinese versions of the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder scale (GAD-7), the 7-item Insomnia Severity Index (ISI), and the 22-item Impact of Event Scale-Revised (IES-R) for evaluation of post-traumatic stress disorder (PTSD). The differences between the two groups were analyzed. Results: The scores of BC patients and frontline female nurses for the four scales were significantly higher than those of non-frontline female nurses (P < 0.001). There were similar scores between BC patients and frontline female nurses for PHQ-9, GAD-7, and IES-R (P = 0.789, P = 0.101, P = 0.158, respectively). Notably, the scores of BC patients for ISI were significantly higher than those of the frontline female nurses (P = 0.016). A considerable proportion of BC patients reported symptoms of depression (106/207, 51.2%), anxiety (130/207, 62.8%), insomnia (106/207, 51.2%), and PTSD (73/207, 35.5%), which was more severe than that of female nurses. Conclusions: BC patients experienced great psychological pressure during the COVID-19 outbreak. The incidents of symptomatic anxiety, depression, sleep disorders, and PTSD were significantly comparable to that of frontline female nurses, and episodes of insomnia among BC participants were more serious than for frontline female nurses.

Insomnia among Cancer Caregivers: A Proposal for Tailored Cognitive Behavioral Therapy

Caregivers are relatives, friends, or partners who have a significant relationship with and provide assistance (i.e., physical, emotional) to a patient with often life-threatening, serious illnesses. Between 40 and 76 percent of caregivers for people with cancer experience sleep disturbance. This is thought to be due, in part, to the unique responsibilities, stressors, and compensatory behaviors endemic to caregiving that serve as precipitating and perpetuating factors of insomnia. Sleep disturbances are associated with significant alterations in one's mental and physical health. Once chronic, insomnia does not remit naturally. Cognitive-behavioral therapy for insomnia (CBT-I) is well-suited to address the multifaceted contributing factors unique to caregivers' sleep disturbance, yet only one intervention has tested a CBT-I informed intervention among cancer caregivers. Toward the goal of developing effective, tailored treatments for insomnia in caregivers, we address the distinct presentation of insomnia among cancer caregivers and describe key modifications to standard CBT-I that address these specific needs and enhance sensitivity and feasibility, modeled in a demonstrative case vignette. Future research must seek to provide a wide range of effective treatment options for this population, including internet-based, dyadic, and alternative integrative medicine treatments. Applicability of key modifications for caregivers of patients with other chronic illnesses is discussed. Establishing empirically-supported interventions for insomnia among cancer caregivers has the potential to enhance their quality of life and care provided, lead to improved bereavement outcomes, and attenuate the notable mental and physical health disparities present in this vulnerable population.
