Abstract
Suicide is the second leading cause of death among youth aged 15-24 years. Identifying modifiable risk factors relevant to adolescents is crucial for suicide prevention. Sleep patterns have been linked to suicidality in adults, but lack sufficient study in youth. This ecological momentary assessment (EMA) study aimed to explore the relationship between objectively and subjectively measured sleep characteristics and next-day suicidal ideation in high-risk youth. We included 29 adolescents (12-18 years old) admitted to the inpatient psychiatric ward post-suicide attempt or due to suicidal intent within the previous month. We conducted objective (actigraphy) and subjective (sleep diary) sleep pattern assessments over ten consecutive days. Daily suicidal ideation was evaluated using a questionnaire based on the validated C-SSRS interview. A significant positive association was observed between sleep onset latency (SOL) and expressing a "death wish" the following day (OR = 1.06, 95% CI [1-1.11], p = .04), with each minute of longer SOL increased the risk for a death wish the following day by 6%. In addition, a marginally significant negative association was observed between total sleep time (TST) and expressing a "death wish" the following day (OR = 0.57, 95% CI [0.3-1.11], p = 0.1), with each one-hour decrease in objectively measured TST increasing the odds of a death wish by 43%. Our study highlights the interplay between sleep patterns and suicidal ideation, with SOL and TST playing a significant role that may function as proximal risk factors for suicidality and as a target for intervention while treating suicidal youth.

Abstract
BACKGROUND A healthcare system's collapse due to a pandemic, such as the coronavirus disease 2019 (COVID-19), can expose healthcare workers (HCWs) to various mental health problems. This study aimed to investigate the impact of the COVID-19 pandemic on the depression and anxiety of HCWs. METHODS A nationwide questionnaire-based survey was conducted on HCWs who worked in healthcare facilities and public health centers in Korea in December 2020. Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to measure depression and anxiety. To investigate factors associated with depression and anxiety, stepwise multiple logistic regression analysis was performed. RESULTS A total of 1,425 participating HCWs were included. The mean depression score (PHQ-9) of HCWs before and after COVID-19 increased from 2.37 to 5.39, and the mean anxiety score (GAD-7) increased from 1.41 to 3.41. The proportion of HCWs with moderate to severe depression (PHQ-9 ≥ 10) increased from 3.8% before COVID-19 to 19.5% after COVID-19, whereas that of HCWs with moderate to severe anxiety (GAD-7 ≥ 10) increased from 2.0% to 10.1%. In our study, insomnia, chronic fatigue symptoms and physical symptoms after COVID-19, anxiety score (GAD-7) after COVID-19, living alone, and exhaustion were positively correlated with depression. Furthermore, post-traumatic stress symptoms, stress score (Global Assessment of Recent Stress), depression score (PHQ-9) after COVID-19, and exhaustion were positively correlated with anxiety. CONCLUSION In Korea, during the COVID-19 pandemic, HCWs commonly suffered from mental health problems, including depression and anxiety. Regularly checking the physical and mental health problems of HCWs during the COVID-19 pandemic is crucial, and social support and strategy are needed to reduce the heavy workload and psychological distress of HCWs.

Abstract
OBJECTIVES South Africa instituted one of the world's strictest lockdowns during the COVID-19 pandemic, which generated heightened conditions of psychosocial stress and posed widespread mental health risks. Despite the elevated burdens of suicidal behaviors and risk of psychiatric disease in the country, few studies have examined the impacts of psychosocial stress from the pandemic on suicidal ideation in South Africa. This study examined the association between psychosocial stress experienced under the COVID-19 pandemic and adult suicidal ideation, as well as degree to which sleep quality and duration mediated this relationship. METHODS An online survey assessed experiences of COVID-19 psychosocial stress, sleep quality and duration, and suicidal ideation in a sample of 189 South African adults during the second and third waves of the COVID-19 pandemic. A causal inference framework for mediation analysis was used to assess the degree to which sleep quality and duration explained the association between COVID-19 psychosocial stress and suicidal ideation. RESULTS Suicidal ideation was reported in 21% of adults. Adults described having moderate sleep quality and an average of 6.9 hours of sleep per night. COVID-19 psychosocial stress significantly predicted adult suicidal ideation in fully adjusted models. Sleep quality, but not sleep duration, significantly mediated the association between COVID-19 psychosocial stress and suicidal ideation, accounting for 25.9% of the total effect. CONCLUSIONS Poor sleep quality may play an important role in exacerbating the alarming stress-induced mental health effects of the COVID-19 pandemic. Further research is necessary to understand the underlying sleep dynamics and associated psychological and neurobiological processes that perpetuate adult suicidal ideation.

Abstract
Sleep disturbances have been linked to suicidal ideation and behaviors in adolescents. Specifically, insomnia and nightmares are associated with current suicide risk and predict future ideation. Associations between hypersomnia, sleep apnea, and suicide remain inconclusive. Potential biological mechanisms underlying these relationships include executive functioning deficits and hyperarousal. Related psychological factors may include thwarted belongingness, perceived burdensomeness, and negative appraisals. Assessing suicide risk in patients with sleep disturbances, and vice versa, is needed. Therapeutic interventions such as cognitive behavior therapy for insomnia and imagery rehearsal treatment, as well as pharmacologic treatments, show promise in treating sleep disorders and suicidal behavior.

Abstract
BACKGROUND Sleep problems are highly prevalent during COVID-19 pandemic. However, only very limited studies have examined the changing patterns of insomnia symptom before and during the COVID-19 pandemic, and most of these studies were limited to two-wave designs and the variable-centered approach. METHODS The data was taken from a large-scale health-related cohort among Chinese college students. This cohort was a five-wave design and 3834 participants who completed at least two waves were included in the present study. Growth mixture modeling (GMM) was used to estimate trajectory classes for insomnia symptoms, followed by binary logistic regression to explore the association between trajectory classes and subsequent mental health problems. RESULTS GMM analyses extracted four distinct trajectories of insomnia symptoms: stable-low pattern (n = 2897, 75.6 %), increasing pattern (n = 405, 10.6 %), decreasing pattern (n = 182, 4.7 %), and stable-high pattern (n = 350, 9.1 %). Additionally, we found that individuals in stable-high and increasing patterns were more likely to experience mental health problems after the COVID-19 pandemic even after adjusting significant covariates and outcomes at baseline. CONCLUSIONS Appreciable heterogeneity in insomnia symptoms among college students was revealed before and during the COVID-19 pandemic. About 20 % of college students were classified as high-risk patterns of insomnia symptoms. Psychological interventions should target such vulnerable groups to reduce the rates of mental health problems.

Abstract
We examined relationships among sleep quality and forms of social interaction (in-person vs. online) as predictors of change in affect and interpersonal needs (perceived burdensomeness, thwarted belongingness) - correlates of suicidal thoughts and behaviors - during the early COVID-19 pandemic lockdown. New York City undergraduates (N = 58) from four public colleges completed a baseline survey and daily diaries up to 30 days in April-June 2020. Adjusting for relevant covariates, better sleep quality and in-person communication predicted greater positive affect and lower negative affect over time, but online social interaction only predicted greater positive affect and did not predict negative affect. Better sleep quality predicted lower perceived burdensomeness but not thwarted belongingness. Both in-person and online social interaction - but not total hours on social media - predicted lower thwarted belonging and perceived burdensomeness. Greater hours spent on social media each day lessened the relationship between in-person interaction and positive affect and lessened the buffering effect of in-person interaction on perceived burdensomeness. Improving sleep quality and increasing in-person interaction may ameliorate psychological variables that increase risk for suicidal thoughts and behaviors. However, when in-person interaction is limited, such as during the COVID-19 pandemic, online social interaction might be encouraged - depending on the nature of the interactions - to increase positive affect and buffer against suicide-related factors.

Abstract
BACKGROUND The COVID-19 pandemic increases the risk of psychological problems including suicidal ideation (SI) in the general population. In this study, we investigated the risk factors of SI after the COVID-19 pandemic was initially controlled in China. METHODS We conducted an online questionnaire via JD Health APP in China in June 2020. Demographic data, feelings and experiences related to the COVID-19 pandemic and psychological problems were collected. The participants (n = 14,690) were divided into the non-SI and SI groups. A binary logistic regression analysis was used to examine the correlates of SI. RESULTS Nine percent of the participants (1328/14690) reported SI. The regression analysis showed that SI was positively associated with ethnic minority (OR = 1.42 [1.08-1.85]), age (e.g. 18-30 years: OR = 2.31 [1.67-3.20]), having history of mental disorders (OR = 2.75 [2.27-3.35]), daily life disturbance due to health problems (OR = 1.67 [1.38-2.01]), being around someone with the COVID-19 (OR = 1.58 [1.30-1.91]), being uncertain about effective disease control (OR = 1.23 [1.03-1.46]), and having depressive symptoms (OR = 4.40 [3.59-5.39]), insomnia symptoms (OR = 2.49 [2.13-2.90]) or psychological distress (OR = 1.87 [1.59-2.18]). LIMITATIONS The main limitation is that the cross-sectional design of this study could not allow us to further explore the causality of SI. CONCLUSIONS The prevalence of SI was relatively high in general population after the COVID-19 pandemic was initially controlled in China. SI should be monitored continually after the COVID-19 pandemic.

Abstract
BACKGROUND Insomnia is associated with suicide risk in civilian and military populations. Thwarted belongingness is proposed as a mediator of this relationship under the Interpersonal Theory of Suicide (IPTS). The present study explored how insomnia relates to suicidal ideation in conjunction with thwarted belongingness among civilians, Service members, and Veterans. METHODS Data from the Military Suicide Research Consortium for N = 6556 individuals (6316 with non-missing suicidal ideation status) were divided into 4 subgroups: civilians, never deployed Service members, previously deployed Service members, and Veterans. Robust Poisson models evaluated the associations between insomnia severity/subtype and current suicidal ideation, with bootstrap mediation models assessing thwarted belongingness as a mediator. RESULTS A 5-point increase in insomnia severity was associated with a 38% increased risk for current suicidal ideation among civilians, a 56% greater risk among never deployed Service members, an 83% greater risk among previously deployed Service members, and a 37% greater risk among Veterans. Moreover, active Service members showed greater associations between difficulty falling asleep and staying asleep with suicidal ideation than civilians. These associations were independent of covariates and only mediated by thwarted belongingness among Veterans. CONCLUSIONS The relationship between insomnia and suicide is not purely explained by thwarted belongingness except among Veterans. Future research should explore additional psychological and neurobiological mechanisms connecting insomnia and suicidality.

Abstract
INTRODUCTION Disrupted sleep is associated with non-suicidal self-injury (NSSI) in young adults, but many specific features of sleep continuity and timing have yet to be examined. Additionally, the psychological mechanisms linking sleep to NSSI are unclear. The present study evaluated 14 sleep variables as classifiers of lifetime or recent NSSI and examined potential confounding and mediating factors. METHODS A sample of 885 college students provided measures of sleep continuity (e.g., duration, timing, fragmentation), nightmares, insomnia, and perceived sleep control. Lifetime and past 3-month NSSI were measured using a self-report version of the Columbia Suicide Severity Ratings Scale. Bidirectional stepwise regression identified significant sleep classifiers and subsequent models examined their associations with NSSI after adjusting for covariates and through potential psychological mediators. RESULTS Only absolute social jetlag was associated with recent NSSI, even after adjusting for covariates, such that each additional hour difference between weekday and weekend sleep schedules was associated with a 17% greater risk of recent NSSI. Nightmares, weekend sleep efficiency, and perceived sleep control were associated with lifetime NSSI, although only weekend sleep efficiency remained associated after adjusting for covariates. Bootstrap mediations identified negative urgency as a partial mediator for recent and lifetime NSSI, and lack of premeditation and perceived burdensomeness as partial mediators for lifetime NSSI. CONCLUSIONS The timing and consistency of young adults' sleep schedules may be of greater importance to NSSI among college students than insomnia or insufficient sleep. Future studies of sleep and NSSI should include these measures as potential risk factors. HIGHLIGHTSDifferences between weekday/weekend sleep timing are linked to recent NSSI.Negative urgency partially mediates poor sleep on recent and lifetime NSSI.Sleep shares a multifaceted relationship with NSSI risk in college students.

Karan M, Park H. Sleep quality and cultural orientation among Chinese and Korean undergraduates in the United States. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2022; 70:660-664. [PMID: 32432975 DOI: 10.1080/07448481.2020.1763368] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 03/24/2020] [Accepted: 04/26/2020] [Indexed: 06/11/2023]
Abstract
ObjectiveThe present study examined the relationship between cultural orientation styles and sleep quality among Chinese and Korean undergraduates in the United States. Method: A total of 266 participants (Mage = 20.55 years, SD = 1.93; 49% Chinese, 51% Korean) completed an online survey. Ethnic identity and American identity measures were used to categorize participants into one of four cultural orientations: bicultural, Asian, American, and marginal. Sleep quality was assessed using the well-validated Pittsburgh Sleep Quality Index. Results: Seventy percent of participants were poor-quality-sleepers. Regression models showed that marginal orientation was associated with worse sleep quality as compared to bicultural orientation and Asian orientation. Conclusions: Poor sleep is prevalent among Asian undergraduates in the U.S. and may be further heightened for those who are disconnected from both their ethnic and American cultures. Promoting a sense of cultural connectedness may help to increase their sleep quality.

[PMID: 35774091 PMCID: PMC9237466 DOI: 10.3389/fpsyt.2022.918417] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 05/16/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND COVID-19-related anxiety, sleep problems, and loneliness may be risk factors for school refusal in children and adolescents. However, few studies have examined the mechanisms by which these risk factors cause school refusal. This study examined the process by which COVID-19-related anxiety, sleep problems, and loneliness cause school refusal, using structural equation modeling. METHODS In this cross-sectional questionnaire-based study, 256 (109 male, 147 female, mean age: 15.37 ± 0.48 years) senior high school students were asked to complete the Stress and Anxiety associated with Viral Epidemics-6 questionnaire to assess COVID-19-related anxiety, the Athens Insomnia Scale (AIS), Sleep Debt Index (SDI), and chronotype (MSFsc) to assess sleep problems, the Three-Item Loneliness Scale (TILS) to assess loneliness, and Feelings of School-Avoidance Scale (FSAS) to assess school refusal. RESULTS Structural equation modeling showed that sleep problems affected loneliness (β = 0.52) and feelings of school refusal (β = 0.37), and that loneliness affected feelings of school refusal (β = 0.47). There was no significant pathway of COVID-19-related anxiety on sleep problems, loneliness, or feelings of school refusal. The indirect effect of sleep problems on feelings of school refusal through loneliness was significant. The results of hierarchical multiple regression analysis showed that AIS (β = 0.30) and SDI (β = 0.13) scores were associated with TILS, and AIS (β = 0.26) and MSFsc (β = -0.14) scores were associated with FSAS scores. CONCLUSION The findings of this study showed that sleep problems affected feelings of school refusal via both direct and indirect pathways through the exacerbation of loneliness. To prevent school refusal in adolescents, addressing the indirect pathway via loneliness could be effective in improving insomnia and sleep debt, while addressing the direct pathway could be effective in improving insomnia and chronotype.

Abstract
BACKGROUND The present study explored group differences in suicide-related variables between those with and without psychosis within the context of a psychiatric inpatient sample that included a range of affective disorder diagnoses. METHODS 54 individuals with psychosis and 103 individuals without psychosis (but experiencing other severe and acute mental health issues) were compared, and analyses of indirect effects were conducted to test specificity of thwarted belongingness, perceived burdensomeness, capability for suicide, agitation, and insomnia as accounting for group differences in suicidal ideation. RESULTS Patients without psychosis experienced higher levels of suicidal ideation, perceived burdensomeness, thwarted belongingness, agitation, and insomnia than patients with psychosis. Additionally, perceived burdensomeness and agitation emerged as robust explanatory factors for the relationship between psychosis status and suicidal ideation. LIMITATIONS Future work should include longitudinal analyses to understand temporal relationships between study variables. Additionally, stability of patients' psychotic symptoms was required and therefore may not reflect those at greatest acuity. CONCLUSIONS Although several studies have investigated suicide-related variables among those with psychosis as compared to the general population, the present study is novel in that the severity of these symptoms in those with psychosis is compared to that of those in other acutely ill populations (e.g., major depression, substance use).

Abstract
STUDY OBJECTIVES Insomnia is a risk factor for suicidal behavior including attempts and death by suicide. We investigated whether insomnia symptom severity was associated with suicidality and death by suicide in patients with psychiatric disorders. METHODS The sample included 180 deceased patients with psychiatric disorders seen at Weber Human Services between 2008 and 2018 who completed the Outpatient Questionnaire-45.2 (OQ) prior to death. Insomnia symptom severity was assessed using item 41 from the OQ. Manner of death was determined by death records and autopsy reports. History of suicidality was determined through electronic medical records. Cases were grouped into four lifetime categories: non-suicidal (n = 30), suicidal ideation (n = 36), suicide attempt (n = 95), and death by suicide (n = 19). Demographic, medical, and psychiatric features of each group were compared using linear regression. Logistic regression was used to determine whether insomnia symptom severity was associated with lifetime suicidality severity grouping, adjusting for psychiatric disorders commonly linked to suicidality. RESULTS Lifetime suicidality was associated with sleep problems, fatigue, headaches, and psychiatric disorders (i.e. depressive, personality, and trauma-related disorders). Referenced to the non-suicidal group, greater insomnia symptom severity was significantly associated with suicide attempts and death by suicide, with odds ratios (OR) of OR = 2.67, p = 0.011, and OR = 5.53, p = 0.002, respectively, even after adjusting important psychiatric diagnoses. CONCLUSIONS Results suggest that insomnia symptom severity endorsed during a clinical visit is associated with heightened suicidality, especially suicidal behavior. The presence of insomnia symptoms in patients with psychiatric disorders may indicate risk for suicide and is a target for suicide prevention.

Abstract
ABSRTACTSuicide is a significant public health problem worldwide, and sleep disturbances have negative effects on mental health and suicidality. Several psychological concepts may mediate the relationship between sleep disturbances and suicide. We aimed to investigate the mediating roles of psychological pain and dream anxiety in this relationship. This cross-sectional study included 150 depressive patients with or without recent suicide attempts and 91 healthy controls. The Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), Psychache Scale (PS), and Van Dream Anxiety Scale (VDAS) were used to assess sleep quality, depression severity, psychological pain, and dream anxiety, respectively. Depression group's mean depression, dream anxiety, psychache, and median sleep quality scores were higher than those of the control group. The ROC analyses indicated no relationship between the violence status of the suicides and the mean dream anxiety, sleep quality or psychache scores. Multivariate regression analysis demonstrated that only the depression score predicted suicide attempts. Mediation analyses revealed that both psychache and dream anxiety have full mediator roles in the relationship between sleep disturbance and suicide attempts. Psychotherapeutic approaches to relieve dream anxiety and psychache may help prevent suicide attempts of at-risk individuals.

Abstract
STUDY OBJECTIVES Nocturnal wakefulness is a risk factor for suicide and suicidal ideation in clinical populations. However, these results have not been demonstrated in general community samples or compared to sleep duration or sleep quality. The present study explored how the timing of wakefulness was associated with suicidal ideation for weekdays and weekends. METHODS Data were collected from 888 adults aged 22-60 as part of the Sleep and Healthy Activity, Diet, Environment, and Socialization study. Suicidal ideation was measured by the Patient Health Questionnaire-9, while timing of wakefulness was estimated from the Sleep Timing Questionnaire. Binomial logistic regressions estimated the association between nocturnal (11 pm-5 am) and morning (5 am-11 am) wakefulness and suicidal ideation. RESULTS Nocturnal wakefulness was positively associated with suicidal ideation on weekdays (OR: 1.44 [1.28-1.64] per hour awake between 11:00 pm and 05:00 am, p < 0.0001) and weekends (OR: 1.22 [1.08-1.39], p = 0.0018). Morning wakefulness was negatively associated with suicidal ideation on weekdays (OR: 0.82 [0.72-0.92] per hour awake between 05:00 am and 11:00 am, p = 0.0008) and weekends (OR: 0.84 [0.75-0.94], p = 0.0035). These associations remained significant when adjusting for sociodemographic factors. Additionally, nocturnal wakefulness on weekdays was associated with suicidal ideation when accounting for insomnia, sleep duration, sleep quality, and chronotype (OR 1.25 [1.09-1.44] per hour awake, p = 0.002). CONCLUSION Wakefulness at night was consistently associated with suicidal ideation. Additionally, morning wakefulness was negatively associated with suicidal ideation in some models. Although these findings are drawn from a non-clinical sample, larger longitudinal studies in the general population are needed to confirm these results.

Abstract
Associations between unmet interpersonal needs and different aspects of suicide have been observed in both Western and non-Western cultures using the Interpersonal Needs Questionnaire (INQ). However, measurement invariance is a prerequisite for comparing differences between culturally different groups, and to date, no studies have examined measurement invariance of INQ across cultures. This study aimed to (a) validate Chinese versions of the INQ, (b) assess measurement invariance across gender for the Chinese INQ, (c) assess measurement invariance across Australian and Chinese cultures for the INQ, and (d) comprehensively assess the association of interpersonal needs with suicide ideation. A sample of 469 Australian undergraduates and a sample of 854 Chinese undergraduates were used in this study. For testing measurement invariance across gender, the sample of Chinese undergraduates was split by gender into the Chinese male and Chinese female samples. Five versions of INQ (10-, 12-, 15-, 18- and 25-item) were tested. The 10- and 15-item Chinese INQ demonstrated adequate psychometric properties through various analyses (i.e., reliability, confirmatory factor analysis, and structural equation modeling) and also demonstrated measurement invariance across gender via multigroup confirmatory factor analysis. The 10-item INQ demonstrated measurement invariance across Australian and Chinese cultures. Of the two interpersonal factors, only perceived burdensomeness was significantly associated with suicide ideation. Multigroup structural equation modeling demonstrated that perceived burdensomeness may be a greater risk factor of suicide among Australian undergraduates than among Chinese undergraduates. Practical and theoretical contributions of this study are discussed.

Abstract
Sleep disturbances have been linked to suicidal ideation and behaviors in adolescents. Specifically, insomnia and nightmares are associated with current suicide risk and predict future ideation. Associations between hypersomnia, sleep apnea, and suicide remain inconclusive. Potential biological mechanisms underlying these relationships include executive functioning deficits and hyperarousal. Related psychological factors may include thwarted belongingness, perceived burdensomeness, and negative appraisals. Assessing suicide risk in patients with sleep disturbances, and vice versa, is needed. Therapeutic interventions such as cognitive behavior therapy for insomnia and imagery rehearsal treatment, as well as pharmacologic treatments, show promise in treating sleep disorders and suicidal behavior.

How Is the Presence of Company Related to Thwarted Belongingness in Real Time? Taking a Closer Look at the Conceptualization of the Construct of the Interpersonal Theory of Suicide. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17134873. [PMID: 32640690 PMCID: PMC7369847 DOI: 10.3390/ijerph17134873] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 06/22/2020] [Accepted: 06/25/2020] [Indexed: 12/11/2022]
Abstract
(1) Background: The role of thwarted belongingness (TB) in predicting suicidal ideation, as originally assumed by the Interpersonal Theory of Suicide, is repeatedly challenged by empirical findings. This could be due to an inadequate conceptualization of the construct of TB that is assumed to be influenced by intrapersonal and interpersonal factors. (2) Methods: We examined the associations of TB with intrapersonal variables related to depression, and with interpersonal variables related to an individual’s actual social environment. We analyzed data from an ecological momentary assessment study in psychiatric inpatients with depressive disorders. N = 73 participants rated momentary TB, depressive affect and status of company up to 10 times per day, over a period of six days, on smartphones. (3) Results: TB was lower when assessed while participants were in company compared to when they were alone, and the more desired the company was, the less TB was experienced. Individuals who had a partnership experienced less momentary TB. Furthermore, higher levels of momentary depressive affect, as well as more stable levels of depression, were related to higher levels of TB, and the relation between the presence of company and TB was weaker for more depressed persons. (4) Conclusions: Our findings can be seen as evidence that both intrapersonal and interpersonal factors relate to TB, and thus support the conceptualization of TB as proposed by the Interpersonal Theory of Suicide.

Abstract
BACKGROUND Cognitive arousal is central to models of sleep disturbance and insomnia, but findings remain mixed regarding whether cognitive arousal is associated with objective sleep disturbance and physiologic hyperarousal. This study explored associations of objective nocturnal wakefulness and indicators of physiologic hyperarousal with cognitive arousal in healthy sleepers and individuals with insomnia. METHODS In sum, 52 adults (51.9% women; 18 with insomnia disorder, 34 healthy sleepers) underwent two overnight polysomnography (PSG) studies (adaptation + baseline nights) and a multiple sleep latency test (MSLT). Baseline depression was assessed and presleep cognitive arousal and somatic arousal were recorded for each night. Multivariate regression was used to evaluate associations of PSG sleep parameters with insomnia, cognitive arousal, and somatic arousal. RESULTS Analyses showed that high levels of nocturnal cognitive arousal were associated with prolonged sleep latency, lower sleep efficiency, and shorter total sleep time by PSG on both nights. An association between nocturnal cognitive arousal and wake after sleep onset was observed on night one only. Moreover, greater nocturnal cognitive arousal was associated with greater likelihood of obtaining short sleep and with longer MSLT sleep latencies. Insomnia diagnosis, depression, and somatic arousal were not associated with PSG sleep parameters or MSLT latency. CONCLUSIONS Heightened cognitive arousal at night is linked to objective sleep disturbances and indicators of physiologic hyperarousal at night and during the day. For patients with insomnia, cognitive arousal may contribute to the 24-hr physiologic hyperarousal. Cognitive arousal may be a critical therapeutic target for severe or treatment-resistant sleep disturbance.

Abstract
Objectives: To model the relationship between loneliness and sleep disturbance over time. Method: Data came from the Health and Retirement Study (2006, 2010, 2014 waves; age ≥ 65 years; n = 5,067). Loneliness was measured via the Hughes Loneliness Scale and sleep disturbance via a four-item scale assessing sleep and restedness. Cross-lagged panel modeling (path analysis) was used to jointly examine reciprocal effects between loneliness and sleep disturbance. Results: Higher loneliness correlated with higher sleep disturbance at baseline. There was evidence of reciprocal effects between loneliness and sleep across timepoints. These associations overall remained when accounting for demographics, objective isolation, and depression. Discussion: Although causality cannot be established, the findings indicate that the relationship between loneliness and sleep disturbance is bidirectional. This requires revision to the current theory on sleep disturbance as a mechanism for the relationship between loneliness and health and indicates that effective treatment of sleep disturbance may reduce loneliness.

Abstract
Objectives/Background: Despite findings that insomnia and depression have a bidirectional relationship, the exact psychological mechanisms that link these disorders are largely unknown. The goal of this study was to identify whether social support mediates the relationship between insomnia and depression. Methods: The study sample (N = 115) consisted of females only, and all participants (mean age 21.77 ± 1.80) completed self-report measures of insomnia severity, depression, and social support. Results: Insomnia severity was significantly associated with low levels of social support (B = -1.04, SE = .27, p < .001) and high levels of depression (B = .18, SE = 0.05, p < .001). Social support mediated the effects of insomnia on depression (95% CI [.03, .15]). However, social support did not mediate the effects of depression on insomnia (95% CI [-.01, .32]). Conclusions: These findings suggest that interpersonal factors such as social support may be an important factor to consider in female insomnia patients in the context of preventing depression in this population.

Abstract
Depression, anxiety, sleep disturbances and poor relationship functioning often co-occur with the confluence of these factors contributing to greater suicide risk. This study investigated whether the pathways between depression, anxiety, sleep disturbances, and relationship functioning differentiated patients with suicide attempt history from those with suicidal ideation history. Patients seeking partial hospital treatment for severe psychiatric symptoms (N = 180) completed interviews assessing psychiatric and suicidal symptom histories, and self-report measures of sleep behaviors, anxiety, depression, and relationship functioning. Multiple sleep behaviors were examined: duration, sleep onset latency, and bedtime. Bias-corrected bootstrap mediation and moderated mediation analyses with suicide attempt as the moderator were used to evaluate pathways between variables. Among patients with ideation and attempt history, (1) sleep onset latency significantly mediated the association between depression and relationship functioning and that between anxiety and relationship functioning; (2) relationship functioning significantly mediated the association between depression and sleep onset latency and that between anxiety and sleep onset latency. These pathways were not significant among patients with suicidal ideation only. No other sleep behaviors were related to study variables. The reciprocal relationship between disrupted sleep onset latency and poor relationship functioning was specifically linked to more severe psychiatric symptoms among acute patients with suicide attempt histories.

Sleep problem, suicide and self-harm in university students: A systematic review. Sleep Med Rev 2019; 44:58-69. [PMID: 30721844 DOI: 10.1016/j.smrv.2018.12.008] [Citation(s) in RCA: 80] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2018] [Revised: 12/10/2018] [Accepted: 12/31/2018] [Indexed: 12/21/2022]
Abstract
Suicide and self-harm behaviours represent public health concerns, and university students are a particularly high risk group. Identifying modifiable risk factors for the development and maintenance of suicidal thoughts and behaviours is a research priority, as prevention is crucial. Research examining the relationship between poor sleep and self-harm/suicidality within university students is, for the first time, systematically evaluated, critically appraised, and synthesised. This literature consistently demonstrates that insomnia and nightmares are associated with elevated suicide risk of suicidal thoughts and behaviours within this subpopulation of young adults. However, as findings are predominantly derived from cross-sectional investigations, the directionality of this relationship is not yet clear. While research investigating the psychological processes driving these relationships is in its infancy, preliminary findings suggest that thwarted belongingness, socio-cognitive factors and emotional dysregulation could be partly responsible. Methodological limitations are highlighted and a research agenda suggesting the key directions for future research is proposed. Continued research in this area - employing longitudinal designs, and testing novel theoretically derived hypotheses - will be crucial to the development of suicide prevention and intervention efforts.

Insomnia predicts increased perceived burdensomeness and decreased desire for emotional support following an in-laboratory social exclusion paradigm. J Affect Disord 2019; 243:432-440. [PMID: 30273881 PMCID: PMC6192247 DOI: 10.1016/j.jad.2018.09.069] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Revised: 09/11/2018] [Accepted: 09/16/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Research suggests that insomnia is associated with elevated perceptions of loneliness and social disconnection; however, few quasi-experimental studies have tested the relationship between these constructs. This study examined whether insomnia symptom severity predicts changes in perceptions of interpersonal connectedness and desire for emotional support following in-laboratory participation in a social exclusion paradigm. METHODS Young adults (N = 70) completed self-report measures assessing constructs of interest before and after engaging in a social exclusion paradigm (Cyberball). Linear regression analyses were used to evaluate whether baseline insomnia symptom severity predicted perceived burdensomeness, desire for emotional support, and thwarted belongingness after playing Cyberball; analyses controlled for baseline perceived burdensomeness, desire for emotional support, and thwarted belongingness, respectively, as well as baseline social anxiety and depression symptoms. RESULTS Greater insomnia symptom severity significantly predicted greater feelings of perceived burdensomeness following Cyberball participation, beyond baseline perceived burdensomeness, social anxiety symptoms, and depression symptoms (β= .24, p = .001). More severe insomnia symptoms also significantly predicted lower desire for emotional support after playing Cyberball, beyond baseline desire for emotional support and social anxiety symptoms (β= -.14, p = .03) but not beyond baseline depression symptoms (β= -.16, p = .07). Insomnia symptoms were not significantly associated with thwarted belongingness after Cyberball (β= -.05-.08, p = .27-.57). LIMITATIONS Replication in larger samples and using other sleep disturbance indices is needed. CONCLUSIONS Findings suggest that individuals with more severe insomnia symptoms in the past two weeks experience greater perceptions of being a burden on others and less desire for emotional support in response to social exclusion.

Abstract
STUDY OBJECTIVES Prior cross-sectional studies indicate that psychological factors (eg, perceived burdensomeness, thwarted belongingness) may explain the relationship between insomnia and suicidal ideation. Longitudinal studies are needed, however, to examine how these variables may relate to one another over time. Using data collected at three time points, this study aimed to evaluate various psychological factors as mediators of the longitudinal relationship between insomnia symptoms and suicidal ideation. METHODS Young adults (n = 226) completed self-report measures of insomnia symptoms, suicidal ideation, and psychological factors (ie, disgust with self, others, and the world; perceived burdensomeness; thwarted belongingness; and loneliness) at baseline (T1), 1-month follow-up (T2), and 2-month follow-up (T3). Bias-corrected bootstrap mediation models were utilized to evaluate each T2 psychological factor as a mediator of the relationship between T1 insomnia symptoms and T3 suicidal ideation severity, controlling for the corresponding T1 psychological factor and T1 suicidal ideation severity. RESULTS Only T2 disgust with others and T2 disgust with the world significantly mediated the relationship between T1 insomnia symptoms and T3 suicidal ideation severity. When both mediators were included in the same model, only T2 disgust with the world emerged as a significant mediator. CONCLUSIONS Findings indicate that disgust with others, and particularly disgust with the world, may explain the longitudinal relationship between insomnia symptoms and suicidal ideation among young adults. These factors may serve as useful therapeutic targets in thwarting the trajectory from insomnia to suicidal ideation. Research is needed, however, to replicate these findings in higher risk samples.

Abstract
OBJECTIVE Research has identified non-suicidal self-injury (NSSI) as a robust correlate of suicidal thoughts and behaviors; however, little is known regarding why these constructs may be related. Consistent with the interpersonal theory of suicide, this study investigated thwarted belongingness (TB), perceived burdensomeness (PB), and capability for suicide (CS) as explanatory links in the association between NSSI, ideation, and suicide attempt history. METHOD Military service members and veterans (N = 973; agemean = 29.9 years, 78.8% male, 63.8% Caucasian/White) completed measures of lifetime NSSI and suicide attempts; current suicidal ideation; TB, PB, and CS; and related psychiatric symptoms. Bootstrap moderated mediation analyses were employed to examine whether (a) TB moderated the mediating effect of PB on NSSI and ideation, (b) PB moderated the mediating effect of TB on NSSI and ideation, and (c) CS moderated the mediating effect of TB and PB on NSSI and attempts. RESULTS TB and PB significantly accounted for the relationship between lifetime NSSI and current ideation. TB did not moderate the mediating effect of PB on NSSI and ideation, and PB did not moderate the mediating effect of TB. However, CS significantly moderated the mediating effects of TB and PB on NSSI and attempt history. CONCLUSIONS The interpersonal theory of suicide hypotheses were partially supported. Consistent with the theory, the interaction of TB and PB only explained NSSI and attempt history among service members with high levels of CS. TB and PB only individually explained the association between lifetime NSSI and recent suicidal ideation. Prospective studies are warranted to replicate these findings across other military samples.

Abstract
Over the past decade, the interpersonal theory of suicide has contributed to substantial advances in the scientific and clinical understanding of suicide and related conditions. The interpersonal theory of suicide posits that suicidal desire emerges when individuals experience intractable feelings of perceived burdensomeness and thwarted belongingness and near-lethal or lethal suicidal behavior occurs in the presence of suicidal desire and capability for suicide. A growing number of studies have tested these posited pathways in various samples; however, these findings have yet to be evaluated meta-analytically. This paper aimed to (a) conduct a systematic review of the unpublished and published, peer-reviewed literature examining the relationship between interpersonal theory constructs and suicidal thoughts and behaviors, (b) conduct meta-analyses testing the interpersonal theory hypotheses, and (c) evaluate the influence of various moderators on these relationships. Four electronic bibliographic databases were searched through the end of March, 2016: PubMed, Medline, PsycINFO, and Web of Science. Hypothesis-driven meta-analyses using random effects models were conducted using 122 distinct unpublished and published samples. Findings supported the interpersonal theory: the interaction between thwarted belongingness and perceived burdensomeness was significantly associated with suicidal ideation; and the interaction between thwarted belongingness, perceived burdensomeness, and capability for suicide was significantly related to a greater number of prior suicide attempts. However, effect sizes for these interactions were modest. Alternative configurations of theory variables were similarly useful for predicting suicide risk as theory-consistent pathways. We conclude with limitations and recommendations for the interpersonal theory as a framework for understanding the suicidal spectrum. (PsycINFO Database Record

Abstract
The Military Suicide Research Consortium (MSRC) developed a 57-item questionnaire assessing suicide risk factors, referred to as the Common Data Elements (CDEs), in order to facilitate data sharing and improve collaboration across independent studies. All studies funded by MSRC are required to include the CDEs in their assessment protocol. The CDEs include shortened measures of the following: current and past suicide risk, lethality and intent of past suicide attempts, hopelessness, thwarted belongingness, anxiety sensitivity, posttraumatic stress disorder symptoms, traumatic brain injury, insomnia, and alcohol abuse. This study aimed to evaluate the psychometric properties of the CDE items drawn from empirically validated measures. Exploratory factor analysis was used to examine the overall structure of the CDE items, and confirmatory factor analyses were used to evaluate the distinct properties of each scale. Internal consistencies of the CDE scales and correlations with full measures were also examined. Merged data from 3,140 participants (81.0% military service members, 75.6% male) across 19 MSRC-funded studies were used in analyses. Results indicated that all measures exhibited adequate internal consistency, and all CDE shortened measures were significantly correlated with the corresponding full measures with moderate to strong effect sizes. Factor analyses indicated that the shortened CDE measures performed well in comparison with the full measures. Overall, our findings suggest that the CDEs are not only brief but also provide psychometrically valid scores when assessing suicide risk and related factors that may be used in future research.

Abstract
Sleep disturbances are associated with suicide-related thoughts and behaviors, and the incidence of sleep concerns and suicide has increased recently in the US. Most published research exploring the sleep-suicidality relation is focused on select sleep disorders, with few reviews offering a comprehensive overview of the sleep-suicidality literature. This narrative review broadly investigates the growing research literature on sleep disorders and suicidality, noting the prevalence of suicide ideation and nonfatal and fatal suicide attempts, the impact of several sleep disorders on suicide risk, and potential sleep-disorder management strategies for mitigating suicide risk. Aside from insomnia symptoms and nightmares, there exist opportunities to learn more about suicide risk across many sleep conditions, including whether sleep disorders are associated with suicide risk independently of other psychiatric conditions or symptoms. Generally, there is a lack of randomized controlled trials examining the modification of suicide risk via evidence-based sleep interventions for individuals with sleep disorders.

Abstract
Loneliness has been repeatedly associated with sleep problems; however, there is a dearth of research examining the prospective relationship between insomnia and loneliness, as well as this association controlling for other psychiatric symptoms. This study evaluated the cross-sectional and prospective relationship between insomnia and loneliness using six samples: 666 undergraduates; 2785 Army recruiters; 208 adults with a history of suicidality and/or depression; 343 adult psychiatric outpatients; 326 young adults at elevated suicide risk; and 183 undergraduates. A meta-analysis also was conducted to examine the magnitude of the relationship between insomnia and loneliness across the six studies. More severe insomnia symptoms were significantly associated with greater feelings of loneliness while accounting for some (e.g., anxiety, nightmares) but not all (i.e., depression) psychiatric covariates. Findings underscore the strength of the association between insomnia and loneliness and suggest that depression may account for this relationship. Additional studies are needed to further establish the temporal relationship between these variables, delineate the role of depression in the association between insomnia and loneliness, and test whether insomnia may confer unique risk for subsequent loneliness.

Abstract
A large data gap remains on suicidal behaviors among youth in the Association of Southeast Asian Nations (ASEAN) countries, despite the increasing rates of suicide in Asian cultures that may be related to rapid economic changes and the loss of social stability. This study was therefore conducted to explore the prevalence of and factors associated with suicidal ideation and suicide attempts among university students in six ASEAN member states. Data were collected in a cross-sectional survey of 4675 undergraduate university students, mean age 20.6 years (SD=2.7), range of 18-30 years, from Cambodia, Indonesia, Malaysia, Myanmar, Thailand and Vietnam. The overall prevalence of ever suicidal ideation and ever suicide attempt among students in this study was 11.7% and 2.4%, respectively. Different rates of these suicidal behaviors were observed across the countries. In multivariable logistic regression models, suicidal ideation was significantly associated with psychosocial factors including childhood sexual abuse, depressive symptoms, involvement in physical fights, and poor academic performance as well as socio-environmental factors including living with parents or guardians and low involvement in organized religious activity. Suicide attempt was significantly associated with childhood sexual abuse, depressive symptoms, low involvement in organized religious activity and being underweight or overweight. Our findings suggest that individual-level strategies for suicide prevention should be targeted toward students with poor academic performance, mental health problems and a history of adverse childhood experiences. Particular attention should be paid to the role of families that could be a potential stressor in the lives of university students.

Abstract
We sought to conduct the first systematic review of empirical evidence investigating the role of psychological factors in the relationship between sleep problems and suicidal thoughts and behaviours. Twelve studies were identified which examined psychological factors grouped into four categories of cognitive appraisals, psychosocial factors, emotion regulation strategies, and risk behaviours. Although there was substantial heterogeneity across studies with respect to measurement, sampling, and analysis, preliminary evidence indicated that negative cognitive appraisals, perceived social isolation, and unhelpful emotion regulation strategies may contribute to the association between sleep problems and suicidal thoughts and behaviours. Given that findings in this area are currently restricted to studies with cross-sectional designs, the directionality of the interrelationships between these psychological factors, sleep problems and suicidality, remains unclear. We integrate the findings of our review with contemporary psychological models of suicidal behaviour to develop a clear research agenda. Identified pathways should now be tested with longitudinal and experimental designs. In addition, a more thorough investigation of the complexities of sleep, psychological factors, and suicidal thoughts and behaviours is crucial for the development of targeted psychological interventions. Systematic review of the role of psychological factors in sleep/suicide relationships Review findings integrated with suicide theory to define a clear research agenda. Reliance on cross-sectional designs limits interpretation of directionality of pathways. Identified pathways should be investigated with longitudinal and experimental designs.

Abstract
BACKGROUND Although insomnia has been identified as a robust predictor of suicidal ideation and behaviors, little is known about the mechanisms by which sleep disturbances confer risk for suicide. We investigated thwarted belongingness as an explanatory link between insomnia symptoms and suicidal ideation across three military service member and veteran samples. METHODS Data were collected among United States military service members and veterans (N1=937, N2=3,386, N3=417) who completed self-report measures of insomnia symptoms, thwarted belongingness, suicidal ideation, and related psychiatric symptoms (e.g., anxiety, hopelessness). Bias-corrected bootstrap mediation analyses were utilized to examine the indirect effects of insomnia symptoms on suicidal ideation through thwarted belongingness, controlling for related psychiatric symptoms. RESULTS Consistent with study hypotheses, thwarted belongingness significantly accounted for the relationship between insomnia and suicidal ideation across all three samples; however, insomnia symptoms did not significantly account for the relationship between thwarted belongingness and suicidal ideation, highlighting the specificity of our findings. LIMITATIONS This study utilized cross-sectional self-report data. CONCLUSIONS Insomnia may confer suicide risk for military service members and veterans, in part, through the pathway of thwarted belongingness. Additional prospective studies are warranted to further delineate this model of risk. Our results offer a potential therapeutic target for the prevention of suicide, via the promotion of belongingness, among service members and veterans experiencing insomnia symptoms.

Abstract
BACKGROUND Insomnia is a robust correlate of suicidal ideation and behavior. Preliminary research has identified thwarted belongingness (c.f. social disconnection) as an explanatory link between insomnia and suicidal ideation. OBJECTIVES This study replicates and extends previous findings using both cross-sectional and longitudinal designs in four demographically diverse samples. Additionally, the specificity of thwarted belongingness was evaluated by testing anxiety as a rival mediator. METHOD Self-report measures of insomnia symptoms, thwarted belongingness, suicidal ideation and behavior, and anxiety were administered in four adult samples: 469 undergraduate students, 352 psychiatric outpatients, 858 firefighters, and 217 primary care patients. RESULTS More severe insomnia was associated with more severe thwarted belongingness and suicidality. Thwarted belongingness significantly accounted for the association between insomnia and suicidality, cross-sectionally and longitudinally, beyond anxiety. Notably, findings supported the specificity of thwarted belongingness: anxiety did not significantly mediate the association between insomnia and suicidality, and insomnia did not mediate the relation between thwarted belongingness and suicidality. LIMITATIONS This study relied solely on self-report measures. Future studies incorporating objective sleep measurements are needed. CONCLUSION Findings underscore the utility of assessing and addressing sleep disturbances and social disconnection to reduce suicide risk.
