School Connectedness and Suicide Among High School Youth: A Systematic Review. THE JOURNAL OF SCHOOL HEALTH 2024; 94:469-480. [PMID: 38383772 DOI: 10.1111/josh.13445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 01/31/2024] [Accepted: 01/31/2024] [Indexed: 02/23/2024]
Abstract
BACKGROUND Suicide is a leading cause of death for adolescents, and school connectedness is a potential, modifiable protective factor for suicide. We sought to examine if school connectedness protected against suicide among high school students and if potential moderators affected the relationship between school connectedness and suicide. METHODS We searched online databases (PubMed, EMBASE, CINAHL, and PsycINFO) on December 12, 2021, for studies that examined the effects of school connectedness on suicide among high school students. RESULTS This systematic review identified 34 studies that examined the effects of school connectedness on adolescent suicidality. Results indicated mixed findings of school connectedness on suicidality. Among studies that assessed a suicide ideation outcome, 73.3% found that school connectedness protected against suicide. Among studies that assessed a suicide attempts outcome, 50% found that school connectedness protected against suicide. Most included studies did not control for notable variables in their final models, such as sleep, impulsivity, substance use, or depression. No studies examined moderators of school connectedness and suicide. CONCLUSIONS School connectedness is somewhat protective of suicidality, and more protective of suicidal ideation than suicide attempts. Researchers should examine the construct of school connectedness among modern youth to better understand school connectedness and suicide.

Comparing actigraphy and diary to measure daily and average sleep in firefighters: a Bland-Altman analysis. J Clin Sleep Med 2024; 20:497-503. [PMID: 37950454 PMCID: PMC10985296 DOI: 10.5664/jcsm.10916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 11/09/2023] [Accepted: 11/10/2023] [Indexed: 11/12/2023]
Abstract
STUDY OBJECTIVES This study sought to examine the relationship between actigraphy and the Consensus Sleep Diary to contribute information on their concurrent validity in a sample of career firefighters. METHODS Sixty firefighters were recruited from a large, urban fire department in the southwest United States that utilizes a fire-based emergency medical services system and a 5/6 shift schedule. A total of 329 differences were recorded during participants' 6-day between-shift recovery period. Data was collected utilizing the two most common forms of sleep analysis in an outpatient setting, wrist actigraphy (Actiwatch-2) and the Consensus Sleep Diary. Nine major sleep indices were computed: wake time after sleep onset, total sleep time, sleep onset latency, sleep offset, in-bed time, lights-off time, out-of-bed time, wake time, and sleep efficiency. RESULTS Firefighters overestimated sleep efficiency and underestimated wake after sleep onset by values that were greater than the American Academy of Sleep Medicine a priori clinical significance thresholds. All indices showed very broad limits of agreement. For example, the 95% confidence interval for diary and actigraphic total sleep time estimates fell within a 4.7-hour range. CONCLUSIONS Firefighters receiving recovery sleep between tours demonstrated significantly large disagreements between their daily self-reported sleep and measured actigraphic sleep. Sleep findings from actigraphic and Consensus Sleep Diary sleep assessments in this population should be interpreted cautiously until each method is compared against other reliable sleep analysis methods. Currently it is unclear if clinicians are using properly validated tools when diagnosing shift work disorder or other sleep disorders in firefighters.

Effects of sleep on breakfast behaviors in recently unemployed adults. Sleep Health 2024; 10:114-121. [PMID: 37973452 PMCID: PMC10922088 DOI: 10.1016/j.sleh.2023.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 08/16/2023] [Accepted: 09/04/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVES Skipping meals is linked to negative cardiometabolic health outcomes. Few studies have examined the effects of breakfast skipping after disruptive life events, like job loss. The present analyses examine whether sleep timing, duration, and continuity are associated with breakfast eating among 186 adults who recently (past 90 days) experienced involuntary unemployment from the Assessing Daily Activity Patterns Through Occupational Transitions (ADAPT) study. METHODS We conducted both cross-sectional and 18-month longitudinal analyses to assess the relationship between actigraphic sleep after job loss and breakfast eating. RESULTS Later sleep timing was associated with a lower percentage of days breakfast was eaten at baseline (B = -0.09, SE = 0.02, P < .001) and longitudinally over 18 months (estimate = -0.04; SE = 0.02; P < .05). No other sleep indices were associated with breakfast consumption cross-sectionally or prospectively. CONCLUSIONS Unemployed adults with a delay in sleep timing are more likely to skip breakfast than adults with an advancement in sleep timing. Future studies are necessary to test chronobiological mechanisms by which sleep timing might impact breakfast eating. With the understanding that sleep timing is linked to breakfast eating, the advancement of sleep timing may provide a pathway for the promotion of breakfast eating, ultimately preventing cardiometabolic disease.

Examining insomnia disorder and stress generation among individuals who have experienced involuntary job loss. J Psychosom Res 2024; 177:111585. [PMID: 38215621 PMCID: PMC10922514 DOI: 10.1016/j.jpsychores.2023.111585] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 12/21/2023] [Accepted: 12/24/2023] [Indexed: 01/14/2024]
Abstract
OBJECTIVE Depressed individuals generate more stressful life events than non-depressed individuals. Like depressive symptoms, the symptoms of insomnia disorder may lead to impaired decision-making, daytime sleepiness, fatigue, and emotion dysregulation, yet the prospective relationship with insomnia disorder and stress generation has not previously been investigated. We hypothesized that insomnia disorder within the first three months of involuntary job loss would lead to an increased number of stressful life events three-months later. METHODS This project employed a longitudinal design consisting of two timepoints occurring approximately 3 months apart. A sample 136 participants with complete data was sourced from the Assessing Daily Activity Patterns through Occupational Transitions study. Insomnia disorder was diagnosed using the Duke Structured Interview for Sleep Disorders, and the number of stressful life events was assessed using the Life Events and Difficulties Schedule. RESULTS A cross-lagged panel analysis utilizing Poisson and logistic regression techniques indicated that insomnia disorder at study baseline predicted an increased number of all stressful life events at follow-up (RR = 1.36, p = .01); conversely, stressful life events at baseline did not predict insomnia disorder (OR = 0.98, p = .87). CONCLUSION These results support a stress-generation hypothesis of insomnia disorder. Findings highlight insomnia disorder as a potential target for intervention in the prevention of additional stress exposure among recently unemployed individuals, who have been shown to be at increased risk for adverse health and health disparities.

Abstract
Objective: Over-the-counter (OTC) and prescription sleep medications are frequently used as treatments for chronic insomnia, despite risks and limited long-term efficacy. Investigating mechanisms underlying this predilection for pharmacotherapy may uncover strategies to decrease reliance on sleep aids. The objective of this study was to determine how time monitoring behavior (TMB; clock-watching) and associated frustration may interact with insomnia symptoms to drive the use of sleep aids. Methods: Patients (N = 4,886) presenting for care at a community-based, private sleep medical center between May 2003 and October 2013 completed the Insomnia Severity Index (ISI) and Time Monitoring Behavior-10 (TMB-10) and reported their frequency of sleep medication use (OTC and prescription, separately). Mediation analyses examined how clock-watching and related frustration could be associated with insomnia symptoms and medication use. Results: The relationship between TMB and sleep medication use was significantly explained by ISI (P < .05), in that TMB (especially related frustration) appears to aggravate insomnia, which in turn leads to sleep aid use. Similarly, but to a lesser extent, the relationship between ISI and sleep medication use was explained by TMB, in that ISI may lead to increased TMB, which may in turn lead to sleep aid use. Conclusions: TMB and the associated frustration it engenders may perpetuate a negative cycle of insomnia and sleep aid use. Future longitudinal and interventional research is necessary to examine the developmental course of these clinical symptoms and behaviors and to test whether decreasing frustration by limiting TMB reduces the proclivity for pharmacotherapy.

Abstract
Objectives Involuntary job loss is a stressful life event that can result in changes in nutritional intake. Both insomnia and obstructive sleep apnea (OSA) also are associated with alterations in dietary intake, but the extent to which this occurs in those who have experienced involuntary job loss is unclear. This study assessed nutritional intake in recently unemployed persons with insomnia and obstructive sleep apnea in comparison to those without a sleep disorder. Methods Participants from the Assessing Daily Activity Patterns through Occupational Transitions (ADAPT) study were screened for sleep disorders using the Duke Structured Interview for Sleep Disorders. They were classified as having OSA, acute or chronic insomnia or no sleep disorder. Dietary data was collected using United States Department of Agriculture Multipass Dietary recall methodology. Results A total of 113 participants had evaluable data and were included in this study. The cohort was comprised mainly of women (62%) and 24% were non-Hispanic white. Participants with OSA had a higher BMI compared with no sleep disorder (30.6 ± 9.1 vs 27.4 ± 7.1 kg/m2, p≤0.001). Those with acute insomnia had significantly decreased consumption of total protein (61.5 ± 4.7 vs. 77.9 ± 4.9 g, p≤0.05) and total fat (60.0 ± 4.4 vs. 80.5 ± 4.6 g, p≤0.05). Among the participants with chronic insomnia, there was little overall difference in nutrient consumption compared to the no sleep disorder group although there were several gender specific differences. There were no overall differences between participants with OSA in comparison to no sleep disorder, but women consumed less total fat (89.0 ± 6.7 vs. 57.5 ± 8.0 g, p≤0.01). The Healthy Eating Index of all groups was below the average value of Americans. Conclusion Unemployed persons compared to those with sleep disorders differ in their consumption of major nutrients; the dietary composition of those with acute insomnia exhibited the greatest divergence. Additionally, the overall nutritional intake of recently unemployed persons is poor.

Abstract
PURPOSE To investigate sleep quantity as a moderator of vaping and self-reported suicidality among adolescents. DESIGN Cross-sectional. Setting: United States high schools. SAMPLE 10,520 high-school students with complete data on the primary outcome of suicide attempt in the past year (76.9% response rate). MEASURES 2019 Youth Risk Behaviors Survey. ANALYSIS Logistic regression to examine main effects and potential moderation. RESULTS Students with under seven sleep hours on school nights (OR = 2.6; 95% CI = 2.1-3.3) and who vaped in the past month (OR = 3.0; 95% CI = 2.1-3.9) had higher odds of attempting suicide in the last year. Sleep quantity moderated the relationship between vaping and suicidal thoughts in the past year (P = .01) but did not moderate the relationship between vaping and a suicide plan (P = .15) or suicide attempts (P = .06). Specifically, vaping had a smaller effect on suicidal thoughts among students who slept under seven hours on school nights (OR = 1.8) compared to the descriptively larger effect among participants with more sleep (OR = 2.5). CONCLUSIONS Students who vape or report low sleep quantity would be ideal participants in suicide prevention interventions as they may be at higher risk for suicidality. Organizations implementing sleep or vaping interventions should incorporate information regarding the higher odds of suicide among students with low sleep quantity or vaping habits.

The impact of social rhythm and sleep disruptions on waist circumference after job loss: A prospective 18-month study. Obesity (Silver Spring) 2022; 30:2023-2033. [PMID: 36062849 PMCID: PMC9509421 DOI: 10.1002/oby.23513] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 05/12/2022] [Accepted: 05/14/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE This study prospectively examined change in waist circumference (WC) as a function of daily social rhythms and sleep in the aftermath of involuntary job loss. It was hypothesized that disrupted social rhythms and fragmented/short sleep after job loss would independently predict gains in WC over 18 months and that resiliency to WC gain would be conferred by the converse. METHODS Eligible participants (n = 191) completed six visits that included standardized measurements of WC. At the baseline visit, participants completed the social rhythm metric and daily sleep diary and wore an actigraph on their nondominant wrist each day for a period of 2 weeks. RESULTS When controlling for obesity and other covariates, WC trajectories decreased for individuals with more consistent social rhythms, more activities in their sdiocial rhythms, and higher sleep quality after job loss. WC trajectories did not change for individuals with lower scores on these indicators. CONCLUSIONS The frequency and consistency of social rhythms after job loss play a key role in WC loss. These findings support the implementation of social rhythm interventions after job loss, a potentially sensitive time for the establishment of new daily routines that have an impact on metabolic health.

Abstract
BACKGROUND Obstructive Sleep Apnea (OSA) is a common sleep-related breathing disorder that often is associated with several psychiatric conditions. Job loss is a stressful life event that can also affect mental health and socioeconomic status (SES). We investigated whether there was an association between the prevalence of OSA and several psychiatric conditions within a cohort of persons who recently became unemployed and whether SES was a contributing factor. METHODS Data from 292 participants who completed the screening evaluation of the Assessing Daily Activity Patterns through occupational Transitions (ADAPT) Study were used to assess the association between the prevalence of OSA, and current and past depression, and past suicidality. A type III sleep home sleep monitor was used to identify the presence of OSA and assess its severity. Depression and suicidality were ascertained using the Mini-international neuropsychiatric interview. Years of education was used as a proxy for SES. RESULTS There were no significant associations between severity of OSA, SES and current depression, past depression, and suicidality. Past suicidality was noted to be more common among those who were single/widowed (17.4%) or those who were divorced or separated (11.1%) (p=0.027). Current depression was more common among Hispanics in comparison to non-Hispanics. Furthermore, prevalence rates of both depression and past suicidality were higher than previous reports in general populations. CONCLUSIONS Within a cohort of individuals who experienced recent job loss, there was no association between OSA and depression or past suicidality. Prevalence rates of both depression and past suicidality were higher than previous reports in the general population.

Abstract
Introduction: Previous studies have linked sleep to risk of diabetes and obesity, at least partially via alterations in food intake. Diabetes and obesity are common among Hispanics/Latinos, and studies are needed to better clarify the role of sleep in health among this group. Utilizing the revised TFEQ-R-18, this study will examine whether eating behaviors such as cognitive restraint, emotional eating and uncontrolled eating are related to self-reported sleep experiences. Specifically, we hypothesized that poor eating habits would be associated with (1) more insomnia symptoms, (2) overall worse sleep quality, (3) increased daytime sleepiness, and (4) shorter sleep duration.Methods: Data were collected from N = 100 adults (age 18-60, 47% female) of Mexican descent in the city of Nogales, AZ (34% not born in the US). Surveys were presented in English or Spanish. Eating Patterns were assessed with the Three-Factor Eating Questionnaire (TFEQ), which resulted in a total score and subscales for "cognitive restraint," "uncontrolled eating," and "emotional eating." Insomnia was assessed with the use of the Insomnia Severity Index (ISI), Sleepiness with the use of the Epworth Sleepiness Scale (ESS), Sleep quality with the use of the Pittsburgh Sleep Quality Index (PSQI), and weekday and weekend sleep duration with the use of the Sleep Timing Questionnaire (STQ). Covariates included age, sex, Body Mass Index (BMI), education and immigrant status.Results: Overall TFEQ score (problematic eating) was positively associated with greater insomnia, poorer sleep quality, more sleepiness, and less weekend (but not weekday) sleep. Mean TFEQ score in the sample was 18.7 (range 0-51). In adjusted analyses, every point on the TFEQ was associated with 0.6 ISI points, 0.8 PSQI points, 0.5 ESS points, and 1.1 minutes of less weekend sleep duration. Regarding subscale scores, relationships were generally seenbetween sleep and emotional eating and unrestricted eating, and not cognitive restraint.Conclusions: Greater insomnia, poorer sleep quality, increased daytime sleepiness and decreased weekend sleep duration were associated with eating patterns at the US-Mexico border, particularly in the area of unrestricted eating and emotional eating. This suggests possible mechanisms linking sleep and obesity in Hispanic/Latinos.

Abstract
<abstract>
<p>Emergency telecommunicators are essential first responders tasked with coordinated communication within the emergency response system (ERS). Despite their exposure to significant job demands, little is known about the effect of call load or call type on emotional state within these workers. Therefore, we employed a prospective, intensive longitudinal design to examine whether emergency-eligible call volume would lead to higher intensity negative emotions post-shift when controlling for pre-shift negative emotions and a number of other work and individual factors, including work duration and night shift. A total of 47 ERS telecommunicators (dispatchers, operators, other) completed ratings over working shifts within a two-week period. Call frequency was gathered through the agency Computer-Assisted Dispatch database. Negative emotions of irritation, stress, worry, and fatigue were measured through the Visual Analogue Scale administered before and after shift. Mixed linear modeling demonstrated that telecommunicators who received more calls per hour (Estimate = 3.56, SE = 1.44, p < 0.05) and more-than-usual calls per hour (Estimate = 1.97, SE = .94, p < 0.05) had higher levels of post-shift irritability. Longer-than-usual working hours also predicted higher levels of post-shift irritability (Estimate = 1.32, SE = 0.59, p < 0.05). Call volume did not predict other negative emotions, although secondary analyses demonstrated that a larger number of chronic calls lead to greater levels of post-shift worry. ERS telecommunication agencies aiming to reduce negative emotions in workers may benefit from implementing policies and programs that target working hours, call load, and work-life balance.</p>

Abstract
Nurses may experience frequent nightmares due to stressful work environments. Nightmares may also exacerbate stress among nurses, although this has yet to be tested empirically. We examined daily bidirectional associations between stress severity and nightmares, and moderation by post-traumatic stress disorder (PTSD) symptoms. 392 nurses (92% female; 78% White) completed 14 days of sleep diaries to assess previous-day stress severity and nightmare occurrence and severity. PTSD symptoms were assessed at baseline. Multilevel models were used to examine bidirectional, within-person associations between daily stress and nightmares, and cross-level moderation by baseline PTSD symptoms. 47.2% of nurses reported at least one nightmare across the two weeks. Days with greater stress were associated with higher odds of experiencing a nightmare (OR = 1.22, p = 0.001), as well as greater nightmare severity (b = 0.09, p = 0.033). Nightmare occurrence was associated with greater next-day stress severity (b = 0.15, p < 0.001). Daily stress and nightmare associations were similar for those with and without PTSD symptoms. Nightmares and stress may occur in a bidirectional fashion. Nurses face intense occupational demands and frequent exposure to potentially traumatic events. Studies should explore whether targeting nightmares and stress may improve nurses' health and well-being.

Abstract
BACKGROUND The International Classification of Sleep Disorders (ICSD)-3 was developed to aid in the identification of these disorders. The core criterion A (ICSD-3A) to identify obstructive sleep apnea (OSA) requires the presentence of specific signs and symptoms. This study explores the predictive ability of the ICSD-3A for OSA as compared with objective measures of respiratory event index (REI). PARTICIPANTS A total of 291 participants who completed a home sleep apnea test (HSAT) during the screening evaluation of the Assessing Daily Activity Patterns through occupational Transitions (ADAPT) study were included. METHODS Participants were classified as having mild OSA (REI ≥ 5 and < 15), moderate (≥ 15 to < 30), or severe OSA (> 30). Predictive parameters identifying participants as having OSA by the ICSD-3A criteria were assessed using REI classifications as the reference standard and further compared with a subsample using the STOP-Bang questionnaire. RESULTS The ICSD-3A had a sensitivity of 19.2% for identifying participants as having moderate to severe OSA and specificity of 84.4%. The ICSD-3A had a receiver operating characteristics (ROC) = 0.53. On the subsample of participants, the STOP-Bang questionnaire's ROC is 0.61. Results were similar when examining the classification of participants with mild compared with no OSA. CONCLUSION In this population, the ability of the ICSD-3A in detecting moderate to severe OSA as well as mild OSA was low. The ROC for the ICSD-3 did not differ significantly from the STOP-Bang questionnaire's ROC in this research population.

Abstract
To examine how sleep quality and sleep duration affect caloric intake among those experiencing involuntary job loss. Methods Adequate sleep and self reported dietary recall data from the Assessing Daily Activity Patterns through Occupational Transitions (ADAPT) study was analysed. Primary sleep indices used were total sleep time, time spent in bed after final awakening, and sleep quality as measured by the Daily Sleep Diary (DSD). Mean Energy consumption (MEC) was the primary nutritional index. Secondary indices included diet quality using the Health Eating Index 2015 (HEI), and self-reported intake of protein, carbohydrates and fats. Results The study participants were comprised mainly of women (61%) and non-Hispanic white. The participants had at least 2 years of college education and mean body mass index of 30.2±8.08 (kg/m 2). The average time in bed was 541.8 (9.0 hrs) ±77.55 minutes and total sleep time was 461.1 (7.6 hrs) ±56.49 minutes. Mean sleep efficiency was 91±6%, self-reported sleep quality was 2.40±0.57 (0-4 scale, 4 = very good), and minutes earlier than planned morning awakening were 14.36±24.15. Mean HEI score was 47.41±10.92. Although the MEC was below national average for both men and women, male sex was associated with higher MEC. In a fully adjusted model sleep quality was positively associated with MEC. Conclusion Daily overall assessments of sleep quality among recently unemployed persons were positively associated with mean energy consumption. Additionally, the diet quality of unemployed persons was found to be unhealthier than the average American and consistent with the relationship between poor socioeconomic status and lower diet quality.

Abstract
BACKGROUND Workplace stress and unemployment are each associated with disturbances in sleep. However, a substantial gap exists in what we know about the type of workplace stress preceding job loss and the lasting effect workplace stressors may have on long-term health outcomes. We hypothesized that a specific type of workplace stress, hindrance stress, would be a stronger predictor of current insomnia disorder, compared to challenge stress. METHOD Cross-sectional data were analyzed from 191 recently unemployed individuals participating in the ongoing Assessing Daily Patterns through occupational Transitions (ADAPT) study. Participants were administered the Cavanaugh et al. (J Appl Psychol. 85(1):65, 2000) self-reported work stress scale regarding their previous job and the Duke Sleep Interview (DSI-SD), a semi-structured interview assessing ICSD-3 insomnia disorder (chronic and acute). RESULTS Results from logistic regression analyses indicated that hindrance work stress was associated with an increased likelihood of current overall, chronic, and acute insomnia disorder, when controlling for challenge stress and significant demographic factors. Challenge stress was associated with an increased likelihood of chronic insomnia disorder when controlling for hindrance stress and covariates. The association between challenge stress and acute insomnia differed as a function of sex. CONCLUSION Hindrance work stressors were associated with increased odds of current insomnia disorder, even after employment ended. Across each of the tested models, hindrance stress had stronger effects on insomnia than challenge stress. These findings support and extend both the challenge-hindrance framework of work-related stress and the 3 P model of insomnia.

Inconsistent social rhythms are associated with abdominal adiposity after involuntary job loss: An observational study. Obes Sci Pract 2021; 7:208-216. [PMID: 33841890 PMCID: PMC8019278 DOI: 10.1002/osp4.479] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 12/21/2020] [Accepted: 12/22/2020] [Indexed: 01/15/2023] Open
Abstract
Objective Unemployment is an established risk factor for obesity. However, few studies have examined obesity-related health behavior after involuntary job loss specifically. Job loss confers a disruption in daily time structure that could lead to negative metabolic and psychological outcomes through chronobiological mechanisms. This study examines whether individuals with unstable social rhythms after involuntary job loss present with higher abdominal adiposity than individuals with more consistent social rhythms and whether this relationship varies as a function of depressive symptoms. Methods Cross-sectional baseline data (n = 191) from the ongoing Assessing Daily Activity Patterns in occupational Transitions (ADAPT) study were analyzed using linear regression techniques. Participants completed the Social Rhythm Metric-17 (SRM) daily over 2 weeks. They also completed the Beck Depression Inventory II (BDI-II) and participated in standardized waist circumference measurements (cm). Results A significant interaction emerged between SRM and BDI-II demonstrating that less consistent social rhythms were associated with larger waist circumference at lower levels of depressive symptoms. Additional exploratory analyses demonstrated a positive association between the number of daily activities performed alone and waist circumference when controlling for symptoms of depression. Conclusion These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults who have recently, involuntarily lost their jobs. Results highlight the moderating role of depressive symptoms on daily routine in studies of metabolic health. Future prospective analysis is necessary to examine causal pathways.

Abstract
Objective/Background: Fire service shift workers are at risk of developing mental health difficulties related to sleep loss and emotion dysregulation. We aimed to clarify the relationship between off-shift recovery sleep and emotion regulation on stress, fatigue and irritability. Participants: A total of 61 fire service shift workers (e.g. firefighter, captain, engineer, paramedic) on a "5/6" shift. Methods: Following five 24-hour shifts, participants reported on emotion regulation as well as daily sleep, stress, fatigue and irritability during six consecutive off-shift recovery days. Mediation analyses examined (1) emotion regulation as a predictor and sleep as a mediator of stress, fatigue and irritability outcomes; and (2) sleep as a predictor and emotion regulation as a mediator of stress, fatigue and irritability outcomes. Results: Greater self-reported total sleep time predicted lower recovery stress, fatigue, and irritability. Greater subjective sleep efficiency predicted lower recovery stress and fatigue, but not irritability. No significant relationships emerged for objective sleep or emotion regulation variables predicting stress, fatigue or irritability. There were no significant findings with either emotion regulation or sleep variables included as mediators. Conclusions: These findings suggest that stress management programs for fire service shift workers may be most effective when targeting sleep efficiency and quantity rather than emotion regulation strategies in the off-shift recovery period.

Cognitive behavioral social rhythm group therapy versus present centered group therapy for veterans with posttraumatic stress disorder and major depressive disorder: A randomized controlled pilot trial. J Affect Disord 2020; 277:800-809. [PMID: 33065820 DOI: 10.1016/j.jad.2020.09.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 07/17/2020] [Accepted: 09/01/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Cognitive Behavioral Social Rhythm Group Therapy (CBSRT) is a chronobiologically-informed group therapy designed to stabilize social rhythms in veterans with comorbid combat-related PTSD and major depressive disorder (MDD). This randomized controlled pilot trial is the first to examine feasibility and preliminary efficacy of group CBSRT as compared to group Present Centered Therapy (PCT), a well-characterized active attention, psychotherapy condition. METHODS A total of 43 male veterans with combat-related PTSD, MDD, and disruptions in sleep or daily routine were randomly assigned to CBSRT or PCT. Therapy was provided weekly in a group modality for 12 weeks. Follow-up feasibility and gold-standard PTSD, MDD, and subjective/objective sleep assessments were conducted at post-treatment, 3 months, and 6 months post-treatment. RESULTS Feasibility results demonstrated that veterans assigned to CBSRT had higher rates of attendance than veterans assigned to PCT. Both CBSRT and PCT were associated with improvements in PTSD and MDD symptoms, sleep efficiency, and number of awakenings; there were no differences between group therapies on these indices. Veterans in the CBSRT group had a greater reduction in the number of nightmares than veterans in the PCT group. LIMITATIONS Preliminary results must be qualified by the small sample size. CONCLUSIONS Group CBSRT may be more feasible for veterans than PCT. Both CBSRT and PCT were associated with improvements in psychiatric symptoms with few differences between conditions. CBSRT is a promising new group therapy that may help address the high-rate of PTSD therapy attrition in combat veterans. CLINICAL TRIAL REGISTRATION NCT00984698.

Abstract
Background: Patients receiving Cognitive Processing Therapy (CPT), an evidence based therapy for posttraumatic stress disorder (PTSD), report improved sleep quality. However, the majority of studies have examined residual sleep disturbance via self-report surveys or separate items on PTSD measures. This study examined whether CPT delivered to veterans in a VA setting improved sleep indices using state-of-the-art objective and subjective insomnia measures. Participants: Participants were war veterans with a current PTSD diagnosis scheduled to begin outpatient individual or group CPT at two Veteran's Affairs (VA) locations (n = 37). Methods: Sleep symptom severity was assessed using the recommended research consensus insomnia assessment, the consensus daily sleep diary and actigraphy. PTSD symptomatology pre- and post-treatment were assessed using the Clinician Administered PTSD Scale. Results: A small to moderate benefit was observed for the change in PTSD symptoms across treatment (ESRMC = .43). Effect sizes for changes on daily sleep diary and actigraphy variables after CPT were found to be negligible (Range ESRMC = - .16 to .17). Sleep indices remained at symptomatic clinical levels post-treatment. Discussion: These findings support previous research demonstrating a need for independent clinical attention to address insomnia either before, during, or after PTSD treatment.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) has been associated with negative occupational outcomes including absenteeism and poor work productivity. This analysis explored whether the severity of OSA was associated with multiple involuntary job loss history among recently unemployed adults. METHODS This is a cross-sectional analysis of data from the screening visit of the Assessing Daily Activity Patterns Through Occupational Transitions study. Information was collected from 261 participants who recently involuntarily lost their jobs. Data included demographics, employment, medical history, and results from a limited channel home sleep apnea test. The respiratory event index was categorized as <5 events per hour (no-OSA), 5 to <15 (mild OSA), and ≥15 (moderate to severe OSA). Logistic regression and propensity score matching were used to identify factors associated with multiple involuntary job loss. RESULTS A total of 44.8% of participants reported multiple involuntary job loss. Those with mild OSA had 1.85 (95%CI: 1.04, 3.28) increased odds of reporting multiple involuntary job loss as compared to participants with no OSA in the unadjusted model; while participants with moderate-to-severe OSA had 2.71 (95%CI: 1.33, 5.70) increased odds. After adjusting for age, sex, ethnicity, beginning work between 7 and 9 AM, job type, and, compensation type, the odds of involuntary job loss among participants with moderate-severe OSA were 2.46 (95%CI: 1.13, 5.52) as compared to having no OSA. CONCLUSIONS In a sample of recently unemployed adults, having OSA significantly increased the odds of reporting previous involuntary job losses. This study suggests OSA could be a risk factor for job loss.

Abstract
Sleep disparities exist among Hispanics/Latinos, although little work has characterized individuals at the United States (US)-Mexico border, particularly as it relates to acculturation. This study examined the association of Anglo and Mexican acculturation to various facets of sleep health among those of Mexican descent at the US-Mexico border. Data were collected from N = 100 adults of Mexican descent in the city of Nogales, Arizona (AZ). Surveys were presented in English or Spanish. Acculturation was assessed with the Acculturation Scale for Mexican-Americans (ARSMA-II). Insomnia was assessed with the Insomnia Severity Index (ISI), sleepiness was assessed with the Epworth Sleepiness Scale (ESS), sleep apnea risk was assessed with the Multivariable Apnea Prediction (MAP) index, weekday and weekend sleep duration and efficiency were assessed with the Sleep Timing Questionnaire, sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI), and sleep duration and sleep medication use were assessed with PSQI items. No associations were found between Mexican acculturation and any sleep outcomes in adjusted analyses. Anglo acculturation was associated with less weekend sleep duration and efficiency, worse insomnia severity and sleep quality, and more sleep apnea risk and sleep medication use. These results support the idea that sleep disparities may depend on the degree of acculturation, which should be considered in risk screening and interventions.

Marijuana versus evidence-based treatments for sleep and relaxation: A cross-sectional study of use and dose modification following involuntary job loss. Sleep Health 2020; 7:113-117. [PMID: 32758411 DOI: 10.1016/j.sleh.2020.06.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2019] [Revised: 05/27/2020] [Accepted: 06/25/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVES Sleep disruption and relaxation are commonly cited reasons for marijuana use. Job loss is a significant stressor associated with high risk for sleep disruption. Little is known about marijuana use in relation to other intervention choices for sleep/relaxation in individuals who have experienced recent, involuntary job loss. METHODS This study compared self-reported use of marijuana to evidence-based treatments (EBT) for sleep/relaxation using data from the ongoing Assessing Daily Activity Patterns through Occupational Transitions (ADAPT) study. Participants were 1639 completers of the ADAPT phone screen interview. EBT was defined as Cognitive Behavioral Therapy for Insomnia (CBT-I), non-benzodiazepine sedatives/hypnotics, and benzodiazepines. RESULTS Marijuana was the most common treatment for sleep/relaxation. Two-sample tests of proportions revealed that prevalence of use of marijuana was comparable to the entire class of EBTs (~5%). Only 2 (0.1%) participants reported receiving CBT-I, the first-line treatment for insomnia disorder, as per the American College of Physicians Clinical Practice Guidelines. Rates of dose increase following job-loss were comparable between users of marijuana and EBTs (Z = 0.56, p = .58). Multiple logistic regression models demonstrated that male sex (OR = 0.28, 95%CI = 0.14-0.57) and substance abuse (OR = 7.68, 95%CI = 2.89-20.43) were significantly associated with increased likelihood of marijuana use. CONCLUSIONS Individuals who have recently experienced involuntary job loss may be more likely to use marijuana than any one EBT for sleep/relaxation and as likely to increase their treatment dose. Dissemination of evidence-based sleep health interventions is needed in unemployed populations to prevent habitual patterns resulting in the long-term use of marijuana for sleep/relaxation.

Abstract
Abstract
Introduction
Involuntary job loss is an acute stressor that disrupts daily time structure and activity and exacerbates economic hardship and psychological distress. Studies show that unemployment is associated with negative obesity-related health outcomes, such as metabolic syndrome. However, very little is known about daily routine, depression, and obesity in individuals who have recently experienced involuntary job loss. We hypothesized that individuals with less consistent daily routines, or unstable social rhythms, after job-loss would have more abdominal adiposity than individuals with more consistent social rhythms. We also hypothesized that this relationship would vary as a function of depressive symptoms.
Methods
Cross-sectional baseline data (n = 186) from the ongoing ADAPT study (Assessing Daily Activity Patterns through occupational Transitions) were analyzed using linear regression techniques. Participants were predominantly female (62%) with a mean age of 41.12 years (SD = 10.16 years); 31% were Hispanic or Latino. Over two weeks, participants completed the daily Social Rhythm Metric-17 (SRM), Beck Depression Inventory II (BDI), and waist circumference (adiposity) measurements (cm).
Results
A significant BDI x SRM interaction was detected in the prediction of waist circumference, B = .36, SE = .18, <i> p </i> < .05, 95% CI [.002, .709], R2 = .07). The SRM was inversely associated with waist circumference, B = -5.57, SE = 2.25, <i> p </i> < .05, 95% CI [-9.98, -1.13], only at lower levels of BDI (-1 SD below the mean). Results from the Johnson-Neyman technique identified that the conditional effect of SRM on waist circumference was statistically significant at a BDI raw score of 8.33 (0-13 points is minimal depression) with ~45% of cases within this region.
Conclusion
A less consistent daily routine was associated with a larger waist circumference among individuals with minimal depressive symptoms. These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults at high risk for central obesity. Results highlight the moderating role of depression in obesity prevention. Future prospective analysis is necessary to examine causal pathways.

Abstract
Abstract
Introduction
The stress generation hypothesis posits that depressed (versus non-depressed) individuals generate more stressful life events, especially events for which they are at least partly responsible (i.e., dependent events). Insomnia disorder interferes with emotion regulation, potentially leading to impaired decision-making and increased stress generation. We hypothesized that insomnia disorder would lead to an increased number of stressful life events in our sample of adults who have recently experienced involuntary job loss.
Methods
Assessing Daily Activity Patterns through Occupational Transitions is a longitudinal study examining linkages between job-loss, sleep, obesity, and mental health. We used baseline and 3-month follow-up data from 137 participants who completed the Life Events and Difficulties Schedule, a contextual life event measure. Insomnia disorder was coded yes if participants met ICSD-3 criteria for a current chronic or acute insomnia disorder on the Duke Structured Interview for Sleep Disorders. Covariates included age, gender, and race. Linear and logistic regression were employed to assess changes in number of events over time. Secondary analysis examined the relationship between insomnia and dependent stressful life events specifically.
Results
When controlling for covariates, insomnia disorder at study baseline predicted the number of stressful life events generated between baseline and 3-month follow-up (β =.60, se=.30, t=1.99, p=.05). Conversely, events at baseline did not predict insomnia disorder at follow-up when controlling for baseline insomnia disorder (OR=.98, CI=.82-1.17). Secondary analysis revealed a trend toward increased generation of dependent events among individuals with insomnia disorder (β =.37, se=.23, t = 1.6, p=.11).
Conclusion
Our analyses provide preliminary evidence for a causal relationship between insomnia disorder and stress generation. Additional research is needed to replicate and examine the mechanisms behind this relationship. This extension of the stress generation hypothesis may have important implications for harm reduction interventions for insomnia disorder.

Abstract
Abstract
Introduction
Obesity is a major public health concern disproportionately affecting people of lower socioeconomic status. Involuntary job loss is a predictor of economic hardship and unemployment has been associated with poor sleep quality. Little is known about daily sleep and energy intake in this high-risk population. We hypothesized that disrupted, short sleep would be associated with increased energy intake among individuals who experienced involuntary job loss within the last 90 days.
Methods
Complete baseline data were analyzed from the ongoing Assessing Daily Activity Patterns through occupational Transitions (ADAPT) study. Over the same two-week period, participants (n = 191; 117 female; 63 Hispanic) were instructed to complete 14 days of daily sleep diaries and up to three 24-hour dietary recalls, conducted by trained interviewers using the Nutrition Data System for Research. The primary sleep variable was a composite score summarizing standardized number of awakenings and reversed-scored total sleep time; higher scores represented worse sleep. Energy intake was estimated as average 24 hour reported kcals/day. Linear regression was employed with age, gender, and body mass index as covariates.
Results
Higher sleep composite scores were associated with higher self-reported intake in kilocalories (kcal), B = 84.83, SE = 38.01, t = 2.23, <i> p </i> < .05. Wake time after sleep onset, sleep onset latency, and sleep efficiency were not associated with energy intake. Interestingly, higher subjective sleep quality was associated with consumption of more average daily kcals.
Conclusion
In a sample population of adults experiencing stress and economic hardship related to job loss, sleep continuity and quantity were associated with higher energy intake. With further prospective support, these findings suggest that public health interventions for obesity may benefit from behavioral sleep intervention components targeting both sleep fragmentation and sleep restriction.

Abstract
Approximately 50% to 80% of individuals with posttraumatic stress disorder (PTSD) also meet criteria for major depressive disorder (MDD). Sleep disturbance is a major concern in both PTSD and MDD, and is associated with poor treatment response, poor functional outcome and increased suicide risk. Social rhythm regularity, or the consistency of daily habitual behaviors, is theoretically linked to circadian rhythms and may be disturbed in both PTSD and MDD. The present study examined the relationship between social rhythm regularity, sleep disruption and MDD and PTSD symptoms in a sample of veterans with comorbid PTSD and MDD. Baseline data were obtained from 56 male veterans who met DSM-IV criteria for PTSD and MDD. Veterans completed the Social Rhythm Metric (SRM), a self-report questionnaire that assesses the regularity of routines by determining how regularly individuals completed 17 different types of activities. In a linear regression model, increased minutes awake after sleep onset (WASO) was a significant predictor of increased depression scores on the Hamilton Rating Scale for Depression (p < .05). SRM scores did not significantly predict depressive symptoms, however the interaction of WASO and SRM significantly predicted depressive symptoms (p = <.05), with significant relationships found at SRM scores less than 3.62. Neither minutes awake after sleep onset, SRM scores, nor their interaction was associated with PTSD symptom severity. Social and possibly circadian rhythm regularity may represent a risk or resilience factor for individuals with comorbid PTSD and MDD. Findings highlight the importance of exploring the interactions of sleep and social/circadian rhythms in depression in order to inform continued treatment development.

Abstract
BACKGROUND Research demonstrates that poor sleep quality is a predictor of chronic mental and physical health problems. The link between adverse childhood experiences (ACEs) and poor health outcomes is also well established; however, few studies have examined the relationships between ACEs, sleep quality, and physical and mental health. METHODS The current study used structural equation modeling to assess the direct and indirect relationships between ACEs, sleep quality, symptoms of depression and anxiety, and general health perception in a sample of college undergraduates (N = 399), a group of individuals whose age is notable for only recently transitioning out of childhood. RESULTS Indirect (ie, mediation) effects indicated with 95% confidence that sleep quality mediated the relationship between ACEs and general health perception, depressive symptoms, and symptoms of anxiety. Sleep quality did not account for the entire relationship between ACE score and these health outcomes, indicating partial mediation. When reversing the mediator and outcome variables, depression and anxiety fully mediated the relationship between ACE score and sleep quality. CONCLUSION The results of this study suggest that sleep quality may be an important intermediary mechanism by which ACEs might contribute to poor health outcomes and especially poor general health perception. Prospective longitudinal research is needed to examine the directionality of the relationships between ACEs, sleep quality, and physical and mental health outcomes over time.

Abstract
Cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) is an effortful process requiring engagement in cognitive restructuring. Sleep disorders may lead to avoidance of effortful tasks and cognitive performance deficits. We explored whether sleep disorders, as assessed by polysomnography, were consistently associated with treatment response in combination with other factors. This study included 32 U.S. veterans who were examined both before and after CPT for combat-related PTSD. We employed a novel, case-comparative technique, fuzzy set qualitative comparative analysis (fsQCA), to identify combinations of fuzzy and crisp factors (recipes) that achieve a clinically significant outcome. Approximately one-quarter of cases experiencing clinically significant change were either (a) Vietnam era veterans without sedating medications, moderate sleep disordered breathing, and severe depression; or (b) non-Vietnam era veterans with sedating medications and without severe periodic limb movements (or significant periodic limb movement arousals). Recipes involving the absence of the relevant sleep disorder were associated with the highest coverage values. These results using fsQCA (a) provide valuable information about the heterogeneity of CPT response and (b) suggest that sleep disorders are important factors to consider in theoretical discussions of who responds to CPT for PTSD.

Background The World Health Organization has identified obesity as one of the most visible and neglected public health problems worldwide. Meta-analytic studies suggest that insufficient sleep increases the risk of developing obesity and related serious medical conditions. Unfortunately, the nationwide average sleep duration has steadily declined over the last two decades with 25% of U.S. adults reporting insufficient sleep. Stress is also an important indirect factor in obesity, and chronic stress and laboratory-induced stress negatively impact sleep. Despite what we know from basic sciences about (a) stress and sleep and (b) sleep and obesity, we know very little about how these factors actually manifest in a natural environment. The Assessing Daily Activity Patterns Through Occupational Transitions (ADAPT) study tests whether sleep disruption plays a key role in the development of obesity for individuals exposed to involuntary job loss, a life event that is often stressful and disrupting to an individual’s daily routine. Methods This is an 18-month closed, cohort research design examining social rhythms, sleep, dietary intake, energy expenditure, waist circumference, and weight gain over 18 months in individuals who have sustained involuntary job loss. Approximately 332 participants who lost their job within the last 3 months are recruited from flyers within the Arizona Department of Economic Security (AZDES) Unemployment Insurance Administration application packets and other related postings. Multivariate growth curve modeling will be used to investigate the temporal precedence of changes in social rhythms, sleep, and weight gain. Discussion It is hypothesized that: (1) unemployed individuals with less consistent social rhythms and worse sleep will have steeper weight gain trajectories over 18 months than unemployed individuals with stable social rhythms and better sleep; (2) disrupted sleep will mediate the relationship between social rhythm disruption and weight gain; and (3) reemployment will be associated with a reversal in the negative trajectories outlined above. Positive findings will provide support for the development of obesity prevention campaigns targeting sleep and social rhythms in an accessible subgroup of vulnerable individuals.

Abstract
Social rhythms are patterns of habitual daily behaviors that may impact the timing of the circadian system directly or indirectly through light exposure. According to the social rhythm hypothesis of depression, depressed individuals possess a vulnerability in the circadian timing system that inhibits natural recovery after disrupting life events. Social rhythm therapies (SRTs) support the implementation of regular, daily patterns of activity in order to facilitate recovery of circadian biological processes and also to improve mood. The majority of SRT research has examined interpersonal and social rhythm therapy (IPSRT) for bipolar disorder. Recent studies have examined IPSRT in inpatient settings, using alternative modes of delivery (group, combined individual and group, internet-based applications) and with brief timeframes. New forms of SRTs are developing that target mood in individuals who have experienced specific types of stressful life events. This manuscript reviews the theoretical and biological bases of SRTs and current literature on SRT outcomes.

Abstract
Sleep difficulty is a prevalent problem among returning Veterans. Although there is strong evidence for the efficacy and durability of cognitive-behavioral treatment for insomnia (CBT-I) in the general population, the interventions require motivation, attention, and adherence from patients to achieve successful outcomes. Given the unique characteristics of Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Veterans who have experienced blast-related injuries and other trauma, CBT-I for these patients may require modification, including alternative delivery methods, to ensure effective implementation and positive outcomes. We interviewed 18 OIF/OEF Veterans who screened positive for mild traumatic brain injury and 19 healthcare providers to determine the acceptability of insomnia treatments and preferences for the interventions and treatment delivery. Veterans and providers had distinct preferences for insomnia treatment and its delivery. The treatments the Veterans found most acceptable were also the ones they preferred: relaxation treatment and pharmacotherapy. The providers identified relaxation therapy as the most acceptable treatment. Veterans preferred the individual treatment format as well as electronic methods of treatment delivery. Despite some differences between patients and providers, a compromise through modification of empirically supported behavioral treatments is feasible, and implications for preference-based insomnia intervention development and testing are discussed.

Abstract
STUDY OBJECTIVES To evaluate patient ratings of the acceptability of a peer buddy system (PBS). To promote continuous positive airway pressure (CPAP) therapy adherence in patients with obstructive sleep apnea (OSA). To obtain preliminary data on the effectiveness of PBS on sleep-specific health-related quality of life and CPAP adherence. DESIGN Prospective, randomized, and controlled study. SETTING Academic Center. PARTICIPANTS Thirty-nine patients with OSA and 13 patients with OSA who were experienced CPAP users. INTERVENTIONS Recently diagnosed patients with OSA were randomly assigned to either the PBS to promote CPAP adherence (intervention group) or usual care (control group). MEASUREMENTS Patient satisfaction, Functional Outcomes of Sleep Questionnaire (FOSQ), CPAP adherence, vigilance, self-efficacy, and patient activation were measured. RESULTS Ninety-one percent of the subjects rated the PBS as very satisfactory (68%) or satisfactory (23%). During the 90 days of therapy, weekly CPAP adherence was greater in the intervention than the usual care group (MANOVA; F = 2.29; p = 0.04). Patient satisfaction was positively correlated with CPAP adherence (R(2) = 0.14; p = 0.02). We did not find any group differences for FOSQ, vigilance, self-efficacy, or patient activation in this pilot study. CONCLUSION Our pilot study suggests that the PBS intervention is feasible and received high patient satisfaction ratings. CPAP adherence may be improved by peer-driven intervention, but a larger, adequately powered study is needed. CLINICAL TRIAL INFORMATION ClinicalTrials.gov identifier: NCT01164683.

Abstract
Strong evidence supports the efficacy of cognitive behavioral therapy for insomnia (CBTI). A significant barrier to wide dissemination of CBTI is the lack of qualified practitioners. We describe challenges and decisions made when developing a CBTI dissemination program in the Veterans Health Administration (VHA). The program targets mental health clinicians from different disciplines (psychiatry, psychology, social work, and nursing) with varying familiarity and experience with general principles of cognitive behavioral therapies (CBT). We explain the scope of training (how much to teach about the science of sleep, comorbid sleep disorders, other medical and mental health comorbidities, and hypnotic-dependent insomnia), discuss adaptation of CBTI to address the unique challenges posed by comorbid insomnia, and describe decisions made about the strategy of training (principles, structure and materials developed/recommended). Among these decisions is the question of how to balance the structure and flexibility of the treatment protocol. We developed a case conceptualization-driven approach and provide a general session-by-session outline. Training licensed therapists who already have many professional obligations required that the training be completed in a relatively short time with minimal disruptions to training participants' routine work responsibilities. These "real-life" constraints shaped the development of this competency-based, yet pragmatic training program. We conclude with a description of preliminary lessons learned from the initial wave of training and propose future directions for research and dissemination.

Mindfulness-based cognitive therapy improves polysomnographic and subjective sleep profiles in antidepressant users with sleep complaints. PSYCHOTHERAPY AND PSYCHOSOMATICS 2012; 81:296-304.

Abstract
BACKGROUND Many antidepressant medications (ADM) are associated with disruptions in sleep continuity that can compromise medication adherence and impede successful treatment. The present study investigated whether mindfulness meditation (MM) training could improve self-reported and objectively measured polysomnographic (PSG) sleep profiles in depressed individuals who had achieved at least partial remission with ADM, but still had residual sleep complaints. METHODS Twenty-three ADM users with sleep complaints were randomized into an 8-week Mindfulness-Based Cognitive Therapy (MBCT) course or a waitlist control condition. Pre-post measurements included PSG sleep studies and subjectively reported sleep, residual depression symptoms. RESULTS Compared to controls, the MBCT participants improved on both PSG and subjective measures of sleep. They showed a pattern of decreased wake time and increased sleep efficiency. Sleep depth, as measured by stage 1 and slow-wave sleep, did not change as a result of mindfulness training. CONCLUSIONS MM is associated with increases in both objectively and subjectively measured sleep continuity in ADM users. MM training may serve as more desirable and cost-effective alternative to discontinuation or supplementation with hypnotics, and may contribute to a more sustainable recovery from depression.

Abstract
Despite the high comorbidity of insomnia with psychiatric illness, few studies have examined insomnia or insomnia treatments in psychiatric inpatients. The present study had two overall goals. First, we sought to describe insomnia symptoms in 76 US veterans hospitalized for a wide-range of psychiatric illnesses. Next, we sought to examine whether participation in one session of group therapy for insomnia was associated with improvement in Insomnia Severity Index (ISI) scores for a subset of these inpatients (n = 19). Data were extracted from the clinical charts of 140 inpatients admitted into the 26-bed psychiatric ward at the New Mexico VA Healthcare System. The majority of the veterans had clinical insomnia in the moderate-to-severe range, and only 18% of the sample reported no clinically-significant insomnia. There was a significant reduction in ISI scores approximately 1 week after attendance at the group therapy session, which appears to be unrelated to the length of hospitalization, but might be related to psychiatric stabilization. This is the first study to examine insomnia symptoms in a mixed, psychiatric inpatient population. Group therapy for insomnia might be a particularly useful treatment option given polypharmacy and substance dependency issues often arising in this population.

Abstract
This issue of the Journal of Clinical Psychology: In Session focuses on the treatment of insomnia and sleep disturbances in a variety of populations. Over the past decade, there has been an increased recognition of the importance of sleep to health and well-being. Despite this recognition, there continues to be a shortage of practitioners with experience in insomnia therapies. In this article, the authors identify and refute commonly held myths that might hinder the treatment of sleep problems. They conclude by introducing the seven articles that constitute this special issue.
