Abstract
STUDY OBJECTIVES Sleep disturbance may cause suicidal ideation (SI). This study aimed to examine their co-occurrence rate among adolescents and investigate whether psychotic-like experiences (PLEs) mediate this association. METHODS A total of 17 722 Chinese adolescents were included in this two-wave longitudinal study. The baseline survey (time 1, T1) was conducted between April 21 and May 12, 2021, and the follow-up survey (time 2, T2) was implemented between December 17 and 26, 2021. At T1, participants completed questionnaires to assess their sleep disturbance, sleep duration, PLEs, SI, depressive symptoms, and sociodemographic characteristics. At T2, participants reported their PLEs, SI, and negative life events. RESULTS The SI prevalence decreased from 20.2% (T1) to 18.4% (T2). Participants with SI showed significantly higher prevalence of sleep disturbance and short sleep duration compared to those without SI. Baseline sleep disturbance and short sleep duration were both associated with the increased risk of SI 6 months later. These longitudinal links were mediated by PLEs, independent of baseline covariates and negative life events. CONCLUSIONS These findings provide a novel insight into the mechanism linking sleep problems and suicidality, and stress the significance of assessing and addressing sleep problems and PLEs for adolescent suicide prevention and intervention.

Abstract
OBJECTIVE This study investigates the prevalence and risk factors of internalizing disorders and suicidal behaviors in student-athletes and their non-athlete peers. PARTICIPANTS The sample consisted of 223,226 college students (69,404 student-athletes [31.09%]) who participated in the NCHA-ACHA II survey (Fall 2015-2018). METHODS Items from the NCHA-ACHA II were used to assess severity of depression, anxiety, and suicidal behaviors. Chi-squared Test of Independence and multinomial logistic regressions were used to examine self-reported internalizing symptoms, previous diagnosis, previous use of mental health resources, and suicidal behaviors within student-athletes and non-athletes. RESULTS Findings indicated high rates of internalizing symptoms. Student-athletes, both varsity and intramural/club, displayed decreased odds of internalizing symptoms, self-reported mental health diagnosis, and suicidal behaviors. CONCLUSIONS This study with a national sample expands previous studies showing concerning rates of mental health difficulties, student-athletes demonstrated lower odds. These findings highlight the importance of further research and need for targeted intervention within this population.

Abstract
OBJECTIVES Rates of suicide exposure are high among service members and Veterans and are especially concerning given the link between suicide exposure and subsequent suicide risk. However, to date, it is unclear which individuals who are exposed to suicide are subsequently at high risk for suicide. Latent profile analysis (LPA) can provide information on unique risk profiles and subgroups of service members and Veterans who have higher suicide risk after suicide exposure, which has not yet been empirically studied. The purpose of this study was to utilize LPA to identify subgroups of service members and Veterans who are at the highest risk for suicidal thoughts and behaviors following suicide exposure. METHODS We analyzed data using LPA from 2570 service members and Veterans (82.1% male, 69.5% White, and 12.1% Latino/a/x) who completed the Military Suicide Research Consortium's Common Data Elements, a battery of self-report suicide-related measures. Psychopathology, substance use, mental health service utilization, interpersonal theory of suicide, and suicide exposure variables were used to validate classes. RESULTS Three latent classes emerged from analyses, one low-risk class and two-high risk classes with differing profile compositions (one primarily differentiated by anxiety symptoms and one differentiated by substance use). CONCLUSION Class-specific recommendations for suicide prevention efforts will be discussed.

The prospective relation between borderline personality disorder symptoms and suicide risk: The mediating roles of emotion regulation difficulties and perceived burdensomeness. J Affect Disord 2022; 313:186-195. [PMID: 35772631 DOI: 10.1016/j.jad.2022.06.066] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 05/27/2022] [Accepted: 06/23/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Despite the strong link between borderline personality disorder (BPD) symptoms and suicide risk, little is known about the mechanisms underlying this association. Theory-driven research clarifying the pathways through which BPD symptoms increase suicide risk over time is needed and may highlight relevant treatment targets for decreasing suicide risk among individuals with heightened BPD symptoms. This study examined the prospective relations among BPD symptoms, emotion regulation (ER) difficulties, perceived burdensomeness, thwarted belongingness, and suicide risk across five assessments over a 7-month period. Consistent with the interpersonal theory of suicide, we hypothesized that greater BPD symptoms would predict greater suicide risk over time via greater ER difficulties and, subsequently, greater perceived burdensomeness. METHODS A U.S. nationwide sample of 500 adults (47 % women; mean age = 40.0 ± 11.64) completed a prospective online study, including an initial assessment and four follow-up assessments over the next seven months. RESULTS Results revealed a significant indirect relation between BPD symptoms and greater suicide risk over time through greater ER difficulties and later perceived burdensomeness. Results also provided evidence for transactional relations between BPD symptoms and ER difficulties and suicide risk over time. LIMITATIONS All constructs were assessed via self-report questionnaire data. Our measure of suicide risk focuses on only suicidal ideation, plans, and impulses, and not suicide attempts or preparatory behaviors. CONCLUSIONS Results highlight both ER- and interpersonal-related factors as key mechanisms underlying suicide risk among community adults with BPD symptoms.

Abstract
BACKGROUND Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly related to suicidal ideation and suicide attempts through core ITS variables (i.e., burdensomeness, thwarted belongingness, and suicide capability). METHODS An online sample of Mechanical Turk workers (N = 365) completed measures assessing substance use frequency, burdensomeness, thwarted belongingness, suicide capability, suicidal ideation, and suicide attempts. RESULTS After controlling for relevant clinical and demographic covariates, substance use frequency was indirectly related to suicidal ideation through burdensomeness but not thwarted belongingness. Substance use frequency was indirectly related to suicide attempts through suicide capability only. LIMITATIONS The cross-sectional design precludes conclusions about the precise nature and direction of the relations examined. The use of a community sample limits generalizability to more severe substance using samples. CONCLUSIONS Results highlight the relevance of distinct ITS factors in the relation between substance use frequency and both suicidal ideation and suicide attempts. Results may inform specific targets for novel interventions aimed at reducing suicide risk among substance-using individuals.HighlightsSubstance use frequency was indirectly related to SI through burdensomeness.Substance use frequency was not indirectly related to SI through thwarted belongingness.Substance use frequency was indirectly related to SA only through suicide capability.

Abstract
Abstract
Evidence demonstrates increased vulnerability to thoughts and behaviors related to suicide (i.e., suicidal ideation) in students. This study examined the interaction between insomnia-symptoms and student-status (students vs. non-students) on reports of suicidal thoughts of behaviors. A total of 363 (N = 363) university students and 300 (N = 300) members of the general population provided complete data on measures of insomnia-symptoms and suicidal ideation. Students indicated greater reports of both total and lifetime ideation while also considering suicidal behavior within the past year. However, no differences were observed in reports of possible future attempt(s) and the disclosure of suicidal thoughts and behaviors to another person. Moreover, students presenting concurrent symptoms of insomnia reported significantly elevated levels of suicidal ideation relative to nonstudents. These outcomes highlight the possible role of insomnia symptoms in accentuating suicidal thoughts and behaviors in the student population.

Abstract
BACKGROUND Eveningness and insomnia are highly comorbid and closely related to psychopathology in adolescents. We aimed to prospectively investigate the trajectories and associations of eveningness and insomnia with daytime functioning, depression and suicidal risk in adolescents. METHODS A 3-year longitudinal study was conducted among 414 Chinese adolescents. The associations of eveningness and insomnia with daytime functioning, depression and suicidal ideation were analyzed using logistic regressions. RESULTS The prevalence rates of eveningness were similar at baseline and follow-up (19.3% vs 22.5%; p = 0.27), while the prevalence of insomnia increased at follow-up (29.2% vs 40.8%; p < 0.001). Among those eveningness adolescents (n=80) at baseline, 46.2% remained as stable evening-type at follow-up, and among those insomnia adolescents (n=121) at baseline, 64.5% had persistent insomnia at follow-up. Logistic regressions showed that stable, incident, and resolved eveningness were associated with excessive daytime sleepiness (EDS) at follow-up, while only persistent and incident insomnia increased the risk of EDS. Persistent and incident insomnia, as well as stable eveningness were independently associated with depression at follow-up. Persistent and incident insomnia, but not eveningness, were associated with suicidal ideation. LIMITATIONS The outcome assessments were based on self-reported questionnaires and the sample size is modest. CONCLUSIONS Persistent eveningness and insomnia are significantly associated with greater risks of EDS and depression in adolescents, while both persistent and incident insomnia, but not eveningness, increased the risk of suicidal ideation. These findings underscore the importance of addressing sleep and circadian factors in the management of adolescent mood and daytime functioning.

Abstract
The current review provides a quantitative synthesis of the empirical literature on sleep disturbance as a risk factor for suicidal thoughts and behaviors (STBs). A systematic search of PsycINFO, MEDLINE, and the references of prior reviews resulted in 41 eligible studies included in this meta-analysis. Sleep disturbance, including insomnia, prospectively predicted STBs, yielding small-to-medium to medium effect sizes for these associations. Complicating interpretation of these findings however, is that few studies of suicidal ideation and suicide attempts, as well as none of suicide deaths, assessed short-term risk (i.e., employed follow-up assessments of under a month). Such studies are needed to evaluate current conceptualizations of sleep dysregulation as being involved in acute risk for suicidal behavior. This want of short-term risk studies also suggests that current clinical recommendations to monitor sleep as a potential warning sign of suicide risk has a relatively modest empirical basis, being largely driven by cross-sectional or retrospective research. The current review ends with recommendations for generating future research on short-term risk and greater differentiation between acute and chronic aspects of sleep disturbance, and by providing a model of how sleep disturbance may confer risk for STBs through neuroinflammatory and stress processes and associated impairments in executive control.

Abstract
PURPOSE OF REVIEW Several reviews and metanalyses have shown that sleep disturbances, such as insomnia and nightmares, can predict suicidal ideations and behaviors. Common physio-pathological pathways may explain this relationship. However, only in recent years, some research groups have tried to apply this knowledge in the quest for a reliable tool of suicide risk prediction. We aim to describe in this paper the results of studies using ecological or quasi-ecological assessment methods that connect sleep disturbances and suicide risk. RECENT FINDINGS Our review confirms the paucity of studies on this topic. The few studies that we could analyze suggest the interest of ecological methods of sleep assessment since sleep disturbances predicted the onset or worsening of suicidal ideations and behaviors. Ecological assessment of sleep can help to understand how sleep disturbances contribute to the emergence of suicidal ideations and behaviors. Sleep disturbances appear as a promising "real-life" marker of risk, but further studies are needed to determine if sleep monitoring could guide preventive interventions.

Abstract
OBJECTIVE Insomnia is associated with suicidality, although the mechanisms of this association are unclear. This study sought to replicate previous findings showing that insomnia symptoms but not sleep duration are associated with frequency of suicidal ideation in adults. We further investigated whether depression or sleep duration moderates the association between insomnia symptoms and frequency of suicidal ideation. MATERIALS AND METHODS We used the 2005-2006 cycle of the National Health and Nutrition Examination Survey to replicate previously reported findings from the 2007-2008 cycle. We used ordered logistic regression to determine whether insomnia symptoms were associated with frequency of suicidal ideation independently of depression and other potential confounds. To extend these findings, we tested whether depression or sleep duration moderated the association between insomnia symptoms and frequency of suicidal ideation. We further replicated these findings in parallel analyses using the combined data from the 2005-2006 and 2007-2008 cycles. RESULTS This study replicated previous results showing that insomnia symptoms are associated with frequency of suicidal ideation in the NHANES 2005-2006 cycle (OR = 1.09, p < 0.05), even after adjusting for potentially confounding variables, including depression. Neither depression nor sleep duration moderated this association. Difficulty with sleep maintenance insomnia symptoms were most robustly associated with frequency of suicidal ideation (OR ≥ 1.97, p < 0.05). Sleep duration was not robustly associated with suicidal ideation. CONCLUSIONS In this study, we found that insomnia symptoms were uniquely associated with frequency of suicidal ideation. This association cannot be explained by the shared association with depression or sleep duration.
