Mid-to-Late-Life Anxiety and Sleep during Initial Phase of COVID-19: Age- and Sex-Specific Insights to Inform Future Pandemic Healthcare.

This study examined associations between COVID-19-related anxiety and sleep in middle-aged and older adults and tested whether these varied by age or sex. In June/July 2020, middle-aged/older adults aged 50+ (n = 277, 45% women, Mage = 64.68 ± 7.83) in the United States completed measures of sleep and COVID-19-related anxiety. Multiple regressions examined whether anxiety was independently associated with or interacted with age or sex in its associations with sleep health, controlling for age, education, medical conditions, sleep/pain medication use, and COVID-19 status. Greater COVID-19 anxiety was associated with worse sleep quality and daytime dysfunction. COVID-19-related anxiety interacted with age (not sex) in associations with total sleep time and sleep efficiency. Greater anxiety was associated with shorter total sleep time and lower sleep efficiency in oldest-older adults (~73 years old) and youngest-older adults (~65 years old) but not middle-aged adults (~57 years old). In mid to late life, older adults may be most vulnerable to the impact of COVID-19-related anxiety on sleep health. Social and behavioral (e.g., knowledge on age-related vulnerability to COVID-19 risk/morbidity/mortality, uncertainty, and changes to daily routines) and physiological factors (sleep disruption and age-related autonomic dysfunction) may underlie these associations. Interventions that mitigate negative pandemic-related psychological and sleep outcomes may be particularly relevant for older adults.

Subjective-Objective Sleep Discrepancy in a Predominately White and Educated Older Adult Population: Examining the Associations with Cognition and Insomnia.

OBJECTIVES: This study examined associations between various cognitive domains and sleep discrepancy (self-reported versus objectively measured sleep), and evaluated interactive associations with insomnia status (non-insomnia versus insomnia). METHOD: Older adults (N=65, Mage=68.72, SD=5.06, 43 insomnia/22 non-insomnia) aged 60+ reported subjective sleep (7-days of sleep diaries), objective sleep assessment (one-night polysomnography, PSG, via Sleep ProfilerTM during the 7-day period), and completed cognitive tasks (NIH Toolbox-Cognition Battery) measuring attention and processing speed, working memory, inhibitory control, cognitive flexibility, and episodic memory. The sleep diary variable corresponding to same one-night of PSG was used to calculate the sleep discrepancy (diary minus PSG parameter) variables for total sleep time, sleep onset latency, wake after sleep onset, and sleep efficiency. Regression analyses determined independent and interactive (with insomnia status) associations between cognition and sleep discrepancy, controlling for age, sex, apnea-hypopnea index, and sleep medication usage. RESULTS: Working memory interacted with insomnia status in associations with sleep discrepancy related to total sleep time and sleep efficiency. In those with insomnia, worse working memory was associated with shorter self-reported total sleep time (p=.008) and lower sleep efficiency (p=.04) than PSG measured. DISCUSSION: In older adults with insomnia, worse working memory may be a contributing factor to sleep discrepancy. Future investigations of underlying neurophysiological factors and consideration of other objective sleep measures (actigraphy) are warranted. Prospective findings may help determine whether sleep discrepancy is a potential marker of future cognitive decline.

Adolescent sleep mediates maternal depressive problems and parenting behaviors: daughter and son differences in a majority Black and Hispanic sample.

STUDY OBJECTIVES: Parents who experience depressive symptoms are less likely to use positive parenting behaviors, in part because of sad affect and inconsistency, which can lead to disengaged parenting. Their children also are more likely to get too little sleep, get too much sleep, or have trouble sleeping, leading to increased child irritability and defiance, which may make it more difficult for a parent to use clear rules and result in more harsh parenting behaviors. The current study examined whether adolescent sleep (too little, too much, trouble sleeping) mediated the relation between maternal depression and parenting behaviors (harsh parenting, positive parenting, clear rules). Further, child gender was examined as a moderator (i.e., moderated mediation). METHODS: The sample (N=318) consisted of mothers reporting on adolescents aged 16-18 (M=16.89, SD=.429; 53.4% female) from the 10th wave of the Schools and Families Educating Children Study (SAFE). Measures included the Child Behavior Checklist (CBCL), Center for Epidemiologic Studies Depression Scale (CESD), and the Parenting Practices Questionnaire (PPQ). RESULTS: Too little sleep mediated the relation between maternal depressive problems and clear rules in the overall sample (ß = .05), and between maternal depressive problems and positive parenting (ß = .11), clear rules (ß = .13), and harsh parenting (ß = .14) for only sons. Too much sleep mediated the relation between maternal depressive problems and harsh parenting in the overall sample (ß = .03), but no mediation occurred for sons and daughters separately. Trouble sleeping did not serve as a mediator in the overall sample but mediated the relation between maternal depressive problems and clear rules for daughters (ß = .03) and between maternal depressive problems and harsh parenting for sons (ß = .09). CONCLUSIONS: These results suggest that adolescent sleep difficulties may be one contributing factor to why mothers who are dealing with depressive symptoms have difficulty using clear rules/positive parenting and use more harsh parenting behaviors. In addition, several of these mediations differed for sons and daughters, indicating important gender differences which may help to better inform and design intervention programs for mothers experiencing depression.

Increasing access to evidence-based insomnia care in the United States: findings from an American Academy of Sleep Medicine stakeholder summit.

Challenges exist in access to high-quality care for insomnia disorder. After the recent publication of a clinical practice guideline on behavioral and psychological treatments for insomnia in adults, the American Academy of Sleep Medicine (AASM) hosted a 1-day virtual Insomnia Summit in September 2022 to discuss improving care for patients with insomnia disorder. Fifty participants representing a variety of organizations (eg, medical, psychological, and nursing associations; patient advocacy groups; and federal institutions) participated in the event. Videos highlighting patient perspectives on insomnia and an overview of current insomnia disorder treatment guidelines were followed by thematic sessions, each with 3 to 4 brief, topical presentations by content experts. Breakout groups were used to brainstorm and prioritize issues in each thematic area. Top barriers to care for insomnia disorder include limited access, limited awareness of treatment options, low perceived value of insomnia treatment, and an insufficient number of trained clinicians. Top facilitators of high-quality care include education and awareness, novel care models to increase access, expanding the insomnia patient care workforce, incorporating research into practice, and increasing reimbursement for psychotherapies. Priorities for the future include increasing awareness among patients and providers, increasing the number of skilled behavioral sleep medicine providers, increasing advocacy efforts to address insurance issues (eg, billing, reimbursement, and performance measures), and working collaboratively with multidisciplinary organizations to achieve common goals. These priorities highlight that goals set to improve accessible, high-quality care for insomnia disorder will require sustained, coordinated efforts to increase awareness, improve reimbursement, and grow the necessary skilled health care workforce.

Sex as a moderator of the sleep and cognition relationship in middle-aged and older adults: A preliminary investigation.

OBJECTIVES: Despite known sex differences in the prevalence of sleep disturbance and cognitive impairment, research investigating sex differences in sleep/cognition associations is limited. We examined sex as a moderator of associations between self-reported sleep and objective cognition in middle-aged/older adults. METHODS: Adults aged 50+ (32 men/31 women, Mage = 63.6 ± 7.7) completed the Pittsburgh Sleep Quality Index (PSQI) and cognitive tasks: Stroop (processing speed, inhibition), Posner (spatial attentional orienting) and Sternberg (working memory). Multiple regressions examined whether PSQI metrics (global score, sleep quality ratings, sleep duration, sleep efficiency) were independently or interactively (with sex) associated with cognition, controlling for age and education. RESULTS: Sex interacted with sleep quality ratings in its association with endogenous spatial attentional orienting (∆R2 = .10, p = .01). Worse ratings of sleep quality were associated with worse orienting in women (B = 22.73, SE = 9.53, p = .02), not men (p = .24). Sex interacted with sleep efficiency in its associations with processing speed (∆R2 = .06, p = .04). Lower sleep efficiency was associated with slower Stroop control trial performance in women (B = -15.91, SE = 7.57, p = .04), not men (p = .48). CONCLUSIONS: Preliminary findings suggest middle-aged/older women are more vulnerable to associations between poor sleep quality and low sleep efficiency on spatial attentional orienting and processing speed, respectively. Future studies in larger samples investigating sex-specific prospective sleep and cognition associations are warranted.

Comparative feasibility and preliminary efficacy of CBT for insomnia among adults seeking and not seeking addiction treatment.

Two out of three adults seeking treatment for alcohol or other substance use disorders report co-occurring symptoms of insomnia. This study compared the feasibility, acceptability, and preliminary efficacy of cognitive behavioural therapy for insomnia (CBT-I) among adults seeking and not seeking treatment for substance use. Adults with alcohol or other substance use disorders (n = 22, 32% female, 82% White; Mage = 39.5) completed assessments at baseline, post-treatment, and at 6 week follow-up. Of those, 11 were and 11 were not enrolled in substance use treatment. All received CBT-I. Multiple imputation was used for missing data. Data were analysed using repeated measures analyses of variance. In the substance use treatment group, 6/11 completed post and 5/11 completed follow-up. In the non-treatment group, 9/11 completed post and 7/11 completed follow-up. Participants in both groups reported improvements in insomnia severity, sleep onset latency, and dysfunctional beliefs about sleep, with most effects evident at post and follow-up. There was a marginal group-by-time interaction in the change in frequency of substance use, with only participants not in substance use treatment reporting decreases at follow-up. Participants in substance use treatment reported significant reductions in substance-related problems and symptoms of post-traumatic stress disorder over time; however, they also reported more symptoms at baseline. CBT-I produces similar reductions in insomnia but is relatively less feasible among individuals in (versus not in) treatment for substance use disorder. This may be due to the more complex logistics of accessing CBT-I among those in treatment. We speculate that integrating CBT-I into treatment for addictions may improve feasibility in this population. clinicaltrials.gov NCT04198311.

Perpetuating and protective factors in insomnia across racial/ethnic groups of veterans.

Few studies have examined racial/ethnic differences in rates and correlates of insomnia among veterans. This study compared rates of insomnia and interest in sleep treatment among veterans of diverse racial/ethnic backgrounds. Consistent with the 3P model, we tested racial discrimination as a predictor of insomnia, with post-traumatic stress disorder symptoms and romantic partners as perpetuating and protective moderators of this association, respectively. A total of 325 veterans (N = 236 veterans of colour; 12% Asian, 36% Black, 14% Hispanic/Latine) completed questionnaires online from remote locations. Descriptive statistics were used to compare patterns across racial/ethnic groups. Linear regression was used to test moderators of the association between racial discrimination and insomnia severity. Overall, 68% of participants screened positive for insomnia: 90% of Asian; 79% of Hispanic/Latine; 65% of Black; and 58% of White participants. Of those, 74% reported interest in sleep treatment, and 76% of those with partners reported interest in including their partner in treatment. Racial discrimination and post-traumatic stress disorder were correlated with more severe insomnia, while romantic partners were correlated with less severe insomnia. Only post-traumatic stress disorder moderated the association between racial discrimination and insomnia severity. Rates of insomnia were highest among Asian and Hispanic/Latine participants, yet these groups were among the least likely to express interest in sleep treatment. Racial discrimination may exacerbate insomnia symptoms among veterans, but only among those who do not already have disturbed sleep in the context of post-traumatic stress disorder. Romantic partners may serve as a protective factor in insomnia, but do not seem to mitigate the impact of racial discrimination.

Preliminary investigation of the interactive role of physiological arousal and insomnia complaints in gray matter volume alterations in chronic widespread pain.

STUDY OBJECTIVES: Brain regions involved in insomnia and chronic pain are overlapping and diffuse. The interactive role of physiological arousal in associations between insomnia symptoms and neural regions is unknown. This preliminary study examined whether arousal interacted with sleep in associations with gray matter volume of frontal (dorsolateral prefrontal cortex, anterior cingulate cortex) and temporal (right/left hippocampus) regions in adults with chronic widespread pain and insomnia complaints. METHODS: Forty-seven adults with chronic widespread pain and insomnia (mean age = 46.00, standard deviation = 13.88, 89% women) completed 14 daily diaries measuring sleep onset latency (SOL), wake time after sleep onset, and total sleep time (TST), as well as Holter monitor assessments of heart rate variability (measuring physiological arousal), and magnetic resonance imaging. Multiple regressions examined whether average SOL, wake time after sleep onset, or TST were independently or interactively (with arousal/heart rate variability) associated with dorsolateral prefrontal cortex, anterior cingulate cortex, and left/right hippocampus gray matter volumes. RESULTS: Shorter TST was associated with lower right hippocampus volume. TST also interacted with arousal in its association with right hippocampal volume, Specifically, shorter TST was associated with lower volume at highest and average arousal levels. SOL interacted with arousal in its association with anterior cingulate cortex volume, such that, among individuals with lowest arousal, longer SOL was associated with lower volume. CONCLUSIONS: Preliminary findings highlight the interactive roles of physiological arousal and insomnia symptoms in associations with neural structure in chronic widespread pain and insomnia. Individuals with the highest physiological arousal may be particularly vulnerable to the impact of shorter TST on hippocampal volume loss. Reducing SOL may only impact anterior cingulate cortex volume in those with lower physiological arousal. CITATION: Curtis AF, Nair N, Hayse B, et al.

Sleep characteristics and pain in middle-aged and older adults: Sex-specific impact of physical and sitting activity.

OBJECTIVES: The relationship between poor sleep health and worse pain is established. Physical activity has been successful in reducing chronic pain and improving sleep in aging adults. Despite known sex differences (more women than men experiencing chronic pain and insomnia), sex-specific patterns of interactive associations between physical activity, sleep, and pain remain unexplored. This study tested whether physical and sitting activity moderated associations between sleep characteristics and pain intensity, and whether sex further moderated these relationships. METHODS: Participants aged 50+ (N = 170, Mage = 64.34, 72 women) completed an online survey measuring pre-sleep arousal (Pre-sleep Arousal Scale), sleep (Pittsburgh Sleep Quality Index), past month average pain intensity, and physical activity (International Physical Activity Questionnaire). Multiple regressions evaluated whether minutes of physical activity (total, vigorous, moderate, walking) or sitting activity, pre-sleep arousal, sleep, sex, or their interaction was associated with pain. Analyses controlled for education, difficulty walking, body mass index, total medical conditions, pain medication, and depressive/anxiety symptoms. RESULTS: In women, vigorous activity interacted with total pre-sleep arousal and somatic pre-sleep arousal in its association with pain. Higher total arousal and somatic arousal were associated with worse pain intensity only for women who reported highest levels of vigorous activity. No such associations were observed for men or for other physical or sitting activity levels. CONCLUSIONS: Vigorous physical activity may exacerbate the association between more pre-sleep arousal and worse pain in middle-aged and older women. Research should explore potential sex-specific mechanisms (e.g., inflammatory cytokines, arousal neural networks) underlying these results.

Development and Initial Evaluation of Web-Based Cognitive Behavioral Therapy for Insomnia in Rural Family Caregivers of People With Dementia (NiteCAPP): Mixed Methods Study.

BACKGROUND: Informal caregivers of people with dementia frequently experience chronic insomnia, contributing to stress and poor health outcomes. Rural caregivers are particularly vulnerable but have limited access to cognitive behavioral therapy for insomnia (CBT-I), a recommended frontline treatment for chronic insomnia. Web-based delivery promises to improve insomnia, particularly for rural caregivers who have limited access to traditional in-person treatments. Our team translated an efficacious 4-session standard CBT-I content protocol into digital format to create NiteCAPP. OBJECTIVE: This study aimed to (1) adapt NiteCAPP for dementia caregivers to create NiteCAPP CARES, a tailored digital format with standard CBT-I content plus caregiver-focused modifications; (2) conduct usability testing and evaluate acceptability of NiteCAPP CARES' content and features; and (3) pilot-test the adapted intervention to evaluate feasibility and preliminary effects on sleep and related health outcomes. METHODS: We followed Medical Research Council recommendations for evaluating complex medical interventions to explore user needs and adapt and validate content using a stepwise approach: (1) a rural dementia caregiver (n=5) and primary care provider (n=5) advisory panel gave feedback that was used to adapt NiteCAPP; (2) caregiver (n=5) and primary care provider (n=7) focus groups reviewed the newly adapted NiteCAPP CARES and provided feedback that guided further adaptations; and (3) NiteCAPP CARES was pilot-tested in caregivers (n=5) for feasibility and to establish preliminary effects. Self-report usability measures were collected following intervention. Before and after treatment, 14 daily electronic sleep diaries and questionnaires were collected to evaluate arousal, health, mood, burden, subjective cognition, and interpersonal processes. RESULTS: The stepped approach provided user and expert feedback on satisfaction, usefulness, and content, resulting in a new digital CBT-I tailored for rural dementia caregivers: NiteCAPP CARES. The advisory panel recommended streamlining content, eliminating jargon, and including caregiver-focused content. Focus groups gave NiteCAPP CARES high usefulness ratings (mean score 4.4, SD 0.79, scored from 1=least to 5=most favorable; score range 4.2-4.8). Multiple features were evaluated positively, including the intervention's comprehensive and engaging information, caregiver focus, good layout, easy-to-access intervention material, and easy-to-understand sleep graphs. Suggestions for improvement included the provision of day and night viewing options, collapsible text, font size options, tabbed access to videos, and a glossary of terms. Pilot-test users rated usefulness (mean score 4.3, SD 0.83; range 4.1-4.5) and satisfaction (mean score 8.4, SD 1.41, scored from 1=least to 10=most satisfied; range 7.4-9.0) highly. Preliminary effects on caregiver sleep, arousal, health, mood, burden, cognition, and interpersonal processes (all P<.05) were promising. CONCLUSIONS: Adaptations made to standard digital CBT-I created a feasible, tailored digital intervention for rural dementia caregivers. Important next steps include further examination of feasibility and efficacy in a randomized controlled trial with an active control condition, a multisite effectiveness trial, and eventual broad dissemination.

Effect of Cognitive Behavioral Therapy for Insomnia on Alcohol Treatment Outcomes Among US Veterans: A Randomized Clinical Trial.

Importance: Three of 4 adults in treatment for alcohol use disorder (AUD) report symptoms of insomnia. Yet the first-line treatment for insomnia (cognitive behavioral therapy for insomnia, CBT-I) is often delayed until abstinence is established. Objective: To test the feasibility, acceptability, and preliminary efficacy of CBT-I among veterans early in their AUD treatment and to examine improvement in insomnia as a mechanism for improvement in alcohol use outcomes. Design, Setting, and Participants: For this randomized clinical trial, participants were recruited through the Addictions Treatment Program at a Veterans Health Administration hospital between 2019 and 2022. Patients in treatment for AUD were eligible if they met criteria for insomnia disorder and reported alcohol use in the past 2 months at baseline. Follow-up visits occurred posttreatment and at 6 weeks. Interventions: Participants were randomly assigned to receive 5 weekly sessions of CBT-I or a single session about sleep hygiene (control). Participants were asked to complete sleep diaries for 7 days at each assessment. Main Outcomes and Measures: Primary outcomes included posttreatment insomnia severity (assessed using the Insomnia Severity Index) and follow-up frequency of any drinking and heavy drinking (4 drinks for women, ≥5 drinks for men; number of days via Timeline Followback) and alcohol-related problems (Short Inventory of Problems). Posttreatment insomnia severity was tested as a mediator of CBT-I effects on alcohol use outcomes at the 6-week follow-up. Results: The study cohort included 67 veterans with a mean (SD) age of 46.3 years (11.8); 61 (91%) were male and 6 (9%) female. The CBT-I group included 32 participants, and the sleep hygiene control group 35 participants. Of those randomized, 59 (88%) provided posttreatment or follow-up data (31 CBT-I, 28 sleep hygiene). Relative to sleep hygiene, CBT-I participants reported greater decreases in insomnia severity at posttreatment (group × time interaction: -3.70; 95% CI, -6.79 to -0.61) and follow-up (-3.34; 95% CI, -6.46 to -0.23) and greater improvements in sleep efficiency (posttreatment, 8.31; 95% CI, 1.35 to 15.26; follow-up, 18.03; 95% CI, 10.46 to 25.60). They also reported greater decreases in alcohol problems at follow-up (group × time interaction: -0.84; 95% CI, -1.66 to -0.02), and this effect was mediated by posttreatment change in insomnia severity. No group differences emerged for abstinence or heavy-drinking frequency. Conclusions and Relevance: In this randomized clinical trial, CBT-I outperformed sleep hygiene in reducing insomnia symptoms and alcohol-related problems over time but had no effect on frequency of heavy drinking. CBT-I should be considered a first-line treatment for insomnia, regardless of abstinence. Trial Registration: ClinicalTrials.gov Identifier: NCT03806491.

Discrepancies in Objective and Subjective Cognition in Middle-Aged and Older Adults: Does Personality Matter?

Associations between subjective cognition and current objective functioning are inconclusive. Given known associations between personality and cognition, this study tested whether personality moderates associations between subjective memory and objective cognition in middle-aged and older adults. Participants (N = 62, M age = 63.8, SD = 7.7, 33 men) completed assessments of personality (Big Five Inventory-10), subjective memory (Cognitive Failures Questionnaire [CFQ-memory]), and objective cognition (processing speed, attention, inhibition [Stroop], working memory [Sternberg], set-shifting [Wisconsin Card Sorting Task]). Multiple regressions and simple slopes analyses examined whether personality moderates associations between subjective memory and objective cognition, controlling for age, number of medical conditions, and household income. Extraversion moderated associations between processing speed and CFQ-memory. Agreeableness moderated associations between set-shifting and CFQ-memory. Among individuals with higher extraversion and lower agreeableness, objectively worse cognition was associated with the fewest memory complaints. Findings suggest personality may impact the discrepancies between subjective memory and objective cognition in mid-to-late life.

Self-reported cognition in older adults with insomnia: Associations with sleep and domain specific cognition.

Poor subjective evaluation of cognition and sleep are associated with cognitive decline in older adults. Relationships among self-reported cognition, sleep, and cognitive domains remain unclear. We evaluated the interactive associations of objective cognition and subjective sleep with self-reported cognition in older adults with insomnia. Fifty-one older adults (Mage  = 69.19, SD = 7.95) with insomnia completed 14 days of self-reported cognition ratings (0-very poor, 100-very good), sleep (total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency), and daily cognitive tasks: Letter series (reasoning), word list delayed recall (verbal memory), Symbol Digit Modalities Test (SDMT) (attention/processing speed), and number copy (processing speed). Multiple regressions for each cognitive task determined whether average objective cognition or sleep were independently/interactively associated with average self-reported cognition, controlling for age, education, and depression. The interaction between SDMT performance and TST was associated with self-reported cognition. Specifically, the relationship between scores and self-reported cognition was congruent in those with the shortest TST. Similarly, the interactions between SDMT and WASO, as well as sleep efficiency, were associated with self-reported. Specifically, the relationship between scores and self-reported cognition was congruent in those with longest and average WASO, as well as shortest and average sleep efficiency. The findings suggest, in an older adult population with insomnia, a congruent association exists between attention/processing speed and self-reported cognition in those with worse subjective sleep (shorter TST, longer WASO, and lower SE). Insomnia symptoms should be taken into consideration when examining the relationship between objective cognition and self-reported cognition.

Is Cognitive Behavioral Therapy for Insomnia Effective for Improving Sleep Duration in Individuals with Insomnia? A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Accumulating evidence suggests that sleep duration is a critical determinant of physical and mental health. Half of the individuals with chronic insomnia report less than optimal sleep duration. Cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment for reducing sleep difficulties in individuals with chronic insomnia. However, its effectiveness for increasing sleep duration is less well-established and a synthesis of these findings is lacking. PURPOSE: To provide a synthesis of findings from randomized controlled trials (RCTs) on the effect of CBT-I on subjective and objective total sleep time (TST). METHODS: A systematic search was performed on articles published from 2004 to 05/30/2021. A total of 43 RCTs were included in the meta-analysis. Publication biases were examined. Meta-regressions were conducted to examine if any sample or treatment characteristics moderated the effect sizes across trials. RESULTS: We found a small average effect of CBT-I on diary-assessed TST at post-treatment, equivalent to an approximately 30-min increase. Age significantly moderated the effects of CBT-I on diary-measured and polysomnography-measured TST; older ages were associated with smaller effect sizes. Contrarily, a negative, medium effect size was found for actigraphy-assessed TST, equivalent to an approximately 30-min decrease. Publication biases were found for diary data at follow-up assessments suggesting that positive findings were favored. CONCLUSIONS: CBT-I resulted in improvements in TST measured by sleep diaries and polysomnography (in adults). These improvements were not corroborated by actigraphy findings. Theoretical and clinical implications were discussed.

Chronic insomnia is a common sleep disorder and can be treated effectively with cognitive behavioral therapy for insomnia (CBT-I). Previous research has consistently shown that CBT-I can reduce sleep difficulties such as difficulty falling and maintaining sleep. The effects of CBT-I on increasing sleep duration are less consistent across studies. This meta-analysis reviewed 43 randomized controlled trials of CBT-I published between 01/01/2004 and 05/30/2021 and synthesized the findings of the effects of CBT-I on sleep duration, measured subjectively and objectively. We found that CBT-I increased sleep duration measured by sleep diaries and polysomnography by about 30 min at post-treatment. This effect is weaker in people with older ages. Contrarily, CBT-I is found to lead to a decrease in sleep duration for about 30 min when sleep duration is measured by actigraphy. The discrepant findings between different sleep measurements reinforce the notion that different measures of sleep assess different aspects of sleep, and that different sleep measurements may have different responsiveness to the treatment of insomnia. Additionally, most people do not achieve the recommended sleep duration at the end of CBT-I. Future studies are needed to evaluate interventions that can help individuals with insomnia increase and maintain optimal sleep duration.

Actigraphic Physical Activity, Pain Intensity, and Polysomnographic Sleep in Fibromyalgia.

INTRODUCTION: Fibromyalgia involves chronic pain and disrupted physical activity and sleep. Research examining the relationship between pre-bedtime physical activity, pain, and objective sleep is limited. This study examined whether objectively measured physical activity levels (via actigraphy), pain intensity, or their interaction are associated with polysomnographic sleep outcomes. METHODS: Adults with fibromyalgia and insomnia complaints (n = 134, mean age = 52 yrs, SD = 12 yrs, 94% female) completed 14 days of biaxial, wrist worn actigraphy, pain ratings, and a single night of polysomnography (PSG). Average activity for intervals 9:00-12:00, 12:00-15:00, 15:00-18:00, 18:00-21:00 was computed. Multiple regressions examined whether average activity, average evening pain, or their interaction were associated with PSG outcomes: sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency, %stage1, %stage2, %stage3, and %rapid eye movement. Analyses controlled for age, body mass index, average bedtime, time in bed, and sleep/pain medication use. RESULTS: Greater morning actigraphic physical activity from 9:00 to 12:00 was independently associated with greater %stage 1 sleep (B = 0.01, SE = 0.00, p < .01). Greater afternoon activity from 12:00 to 15:00 independently predicted a higher WASO (p < .001). Associations between afternoon physical activity from 12:00 to 15:00 and greater %stage 1 (p < .001) were significant for at higher (~71/100), average (~52/100), but not lowest (~32/100) pain. CONCLUSION: Greater morning and afternoon activity is associated with greater PSG sleep fragmentation and greater %stage 1 sleep in individuals with fibromyalgia and insomnia complaints, and the relationship between higher physical activity and greater %stage 1 is stronger for individuals with higher pain. Further studies examining causal pathways between physical activity, activity pacing, and sleep are warranted in fibromyalgia.

Prevalence and correlates of alcohol-induced blackout in a diverse sample of veterans.

BACKGROUND: Alcohol-induced blackouts have been associated concurrently and prospectively with alcohol-related harm. Although rates of heavy drinking among military samples tend to be comparable or higher than rates among civilian samples, the prevalence and correlates of blackout in the military population are understudied. METHODS: Veterans (N = 241, 29% female, 39% Black) reported on their alcohol consumption and mental health as part of a larger health-related study among veterans. In this secondary analysis, we tested theoretically and empirically informed predictors (gender, drinking quantity, and other drug use) and consequences [depression, posttraumatic stress disorder (PTSD)] of alcohol-induced blackout. Given the diversity of the sample, potential roles of racial/ethnic discrimination and drinking to cope in alcohol-induced blackout were also tested. RESULTS: Past-year prevalence of alcohol-induced blackout was 53% among veterans who drank alcohol and 68% among those who screened positive for hazardous drinking. Everyday experience of racial discrimination was the strongest concurrent predictor of alcohol-induced blackout. Drinking quantity and use of other drugs were significant correlates only in bivariate models. Controlling for gender, race, drinking quantity, other drug use, and discrimination, blackout frequency was significantly associated with symptoms of depression, but not symptoms of PTSD. Both blackout and racial discrimination were associated with drinking to cope. CONCLUSIONS: The prevalence and correlates of alcohol-induced blackout among veterans are largely consistent with those documented in civilian and young adult populations. Among racially diverse groups, racial discrimination may be more strongly associated with mental health symptoms than alcohol consumption or acute alcohol consequences such as blackout.

Impact of discrimination and coping on Veterans' willingness to seek treatment for physical and mental health problems.

OBJECTIVE: This study aimed to provide insight into health disparities among Veterans by (a) documenting the prevalence of physical and mental health problems in a racially diverse sample of Veterans, (b) comparing Veterans' willingness to seek treatment for various physical and mental health conditions, and (c) examining the impact of discrimination and coping on willingness to seek treatment. METHOD: Veterans reported on current physical and mental health symptoms and the importance of treatment for various health conditions. Patterns were examined in the full sample (N = 334, 32% female) and the subsample who reported hazardous alcohol use in the past year (n = 116, 33% female). Linear regression was used to test alternative coping as a moderator of the association between experiences with discrimination and willingness to seek treatment among Veterans of color (n = 242, 37% female). RESULTS: Participants reported greater willingness to seek treatment for physical than mental health conditions. Sleep problems (75%) and substance use (74%) were the most prevalent health behaviors, but they were rated lowest in treatment importance. Among Veterans of color, everyday experiences with discrimination were generally associated with less willingness to seek physical or mental health treatment, but often only among those who denied use of coping strategies. CONCLUSIONS: Veterans are least willing to seek treatment for the health conditions that are most prevalent in their communities. Coping strategies may mitigate the negative association between discriminatory experiences and willingness to seek treatment among Veterans of color.

COVID-19-Related Anxiety and Cognition in Middle-Aged and Older Adults: Examining Sex as a Moderator.

Aging populations experience disproportionate risk for cognitive decline, which may be exacerbated by coronavirus (COVID-19) illness, particularly among women. This study tested sex as a moderator of associations between COVID-19 state anxiety and cognition in middle-aged/older adults. Adults aged 50+ (N = 275; 151 men/124 women) completed the Coronavirus Anxiety Scale and Cognitive Failures Questionnaire online from remote locations in July/August 2020. A subset of participants (n = 62) completed an objective cognitive task (Stroop). Multiple regressions determined whether sex moderated associations between COVID-19 anxiety and cognitive outcomes. Sex was a significant moderator, such that for women (not men), greater COVID-19 anxiety was associated with more memory failures and blunders (subjective measures) and worse processing speed (objective measure). COVID-19 state anxiety is linked to everyday cognition and processing speed in women, but not men. Consistency across subjective and objective measures promotes the need for sex-specific understanding of the pandemic's behavioral and cognitive effects in mid-to-late life.

Sex differences in associations between alcohol use and sleep in mid-to-late life.

OBJECTIVES: To examine associations between alcohol use and sleep in middled-aged/older adults and to test sex as a moderator of this relationship. METHODS: Participants were 183 adults (46% female) ages 50 and above who consumed alcohol in the past year. Linear regressions tested sex as a moderator of associations between alcohol use and sleep parameters. Alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT). Overall sleep health and sleep quality were assessed using the Pittsburgh Sleep Quality Index (PSQI), and pre-sleep arousal was assessed using the Pre-Sleep Arousal Scale. RESULTS: Overall, 11% of participants screened positive for hazardous drinking (AUDIT scores of 7+/8+ for women/men), and 59% reported poor overall sleep health (scores >5 on the PSQI). Alcohol use was not associated with overall sleep health (B = -0.25, p = .08) or pre-sleep arousal (B = 0.15, p = .64). However, contrary to hypotheses, more hazardous drinking was associated with better subjective sleep quality, only among women (B = -0.08, p = .009). Alcohol use was not associated with sleep quality among men (B = 0.01, p = .58). Associations remained significant when controlling for age, symptoms of anxiety and depression, body mass index, use of sleep medication, number of medical conditions, and chronic pain. CONCLUSIONS: Among middle-aged and older adults, alcohol use is more strongly associated with sleep patterns among women than men, when assessed concurrently (i.e., at the same time point). Findings support the need for further consideration of sex differences in associations between alcohol use and sleep.

Accrual and retention of diverse patients in psychosocial cancer clinical trials.

Background: Minority and older adult patients remain underrepresented in cancer clinical trials (CCTs). The current study sought to examine sociodemographic inequities in CCT interest, eligibility, enrollment, decline motivation, and attrition across two psychosocial CCTs for gynecologic, gastrointestinal, and thoracic cancers. Methods: Patients were approached for recruitment to one of two interventions: (1) a randomized control trial (RCT) examining effects of a cognitive-behavioral intervention targeting sleep, pain, mood, cytokines, and cortisol following surgery, or (2) a yoga intervention to determine its feasibility, acceptability, and effects on mitigating distress. Prospective RCT participants were queried about interest and screened for eligibility. All eligible patients across trials were offered enrollment. Patients who declined yoga intervention enrollment provided reasons for decline. Sociodemographic predictors of enrollment decisions and attrition were explored. Results: No sociodemographic differences in RCT interest were observed, and older patients were more likely to be ineligible. Eligible Hispanic patients across trials were significantly more likely to enroll than non-Hispanic patients. Sociodemographic factors predicted differences in decline motivation. In one trial, individuals originating from more urban areas were more likely to prematurely discontinue participation. Discussion: These results corroborate evidence of no significant differences in CCT interest across minority groups, with older adults less likely to fulfill eligibility criteria. While absolute Hispanic enrollment was modest, Hispanic patients were more likely to enroll relative to non-Hispanic patients. Additional sociodemographic trends were noted in decline motivation and geographical prediction of attrition. Further investigation is necessary to better understand inequities, barriers, and best recruitment practices for representative CCTs.
