Suicide and Life-Threatening Behavior最新文献

Objective: The purpose of this study was to validate and provide detailed norms on suicide images commonly used in experimental suicide research, and to examine whether appraisals of suicide images varied based on image features and prior suicidal thoughts and behaviors (STBs).

Method: Young adults (N = 264) rated the extent to which images depicted someone "trying to kill themselves on purpose or who did kill themselves on purpose" (i.e., suicide ratings). Suicide ratings were examined descriptively and with bivariate and multivariable statistics.

Results: Suicide images demonstrated construct validity at image and aggregate levels. Further, suicide images looked more like suicide than pleasant, neutral, and interpersonal violence images, bs ≥ 5.653, ts ≥ 52.505, ps < 0.001. Among suicide images, suicide ratings were higher for images without compared to with gore, b = 0.269, t = 7.714, p < 0.001, and for images depicting high lethality methods (e.g., hanging, firearm) compared to the grand mean of all methods, bs ≥ 0.235, ts ≥ 3.316, ps < 0.001. Suicide ratings of suicide images were not associated with prior STBs.

Conclusion: Using valid suicide images, like those tested in the current study, could improve behavioral methods designed to study processes related to STBs.

Background: We continue to have limited success in identifying Veterans at high risk of suicide, due in part to reticence of disclosing suicidal ideation.

Aims: This study used a simulated groups experimental design to evaluate the MMPI-3's ability to assess suicide risk underreporting in Veterans with past-month death/suicide ideation.

Materials and methods: Thirty-nine Veterans (53.85% men) were randomized to standard and simulated underreporting groups and provided valid data on the MMPI-3 and collateral measures. We examined (1) whether simulated underreporting on the MMPI-3 (indexed by L and K scale scores) impacts SUI scale scores, (2) if these effects generalize to underreporting on extratest suicide and non-suicide measures, and (3) if MMPI-3 L and K scales incrementally predict and differentiate between Veterans with recent death/suicide ideation who were instructed to answer honestly and those instructed to underreport.

Results: Groups scored significantly differently on K (g = 0.99: M_simulation = 57.83, M_standard = 43.72), but not L. Underreporting captured by K generalized to lower MMPI-3 SUI scale scores (g = 2.00; M_simulation = 46.33, M_standard = 66.81) and collateral measures of suicide risk (g = 0.69-0.79). K scores significantly predicted group membership and added incrementally to L.

Discussion: The limitations and clinical implications of these findinga are discussed.

Conclusion: MMPI-3 K, but not L, scale scores most reliably capture defensive reporting of suicidal ideation and intent and psychopatholpgy, more boradly. However a signifcant amount of underreporrting of suicidal ideation and intent may go undetected.

Introduction: Sleep disorder symptoms are associated with suicidal ideation, and wakefulness in the middle of the night is associated with an increased risk for suicide, potentially due to deficits in cognitive control. Little is known about daily-level associations among sleep and suicide or about the role of cognitive control in these associations.

Methods: Veterans (n = 32) with past-month suicidal ideation in a residential treatment unit were assessed for 28 days using the suicide visual analogue scale (S-VAS) to assess suicidal urges, a daily sleep diary, and self-reported cognitive control.

Results: Wakefulness in the middle of the night (1-4 a.m.) was associated with the most severe suicidal ideation. Nocturnal wakefulness and sleep quality were each associated with next-day suicidal ideation intensity. Self-reported cognitive control deficits were associated with more intense suicidal ideation. The association between nocturnal wakefulness and suicidal ideation was partially accounted for by self-reported impulsive behavior (7% of variance).

Conclusions: Veterans reported the highest suicidal ideation in the middle of the night. These findings suggest the importance of assessing sleep, suicidal ideation, and cognitive control among veterans and the need to consider nocturnal wakefulness as an indicator of heightened risk for suicide among veterans.

Introduction: Emotional variability has been identified as a risk factor for adolescent psychopathology. This study explored the cross-sectional and prospective associations between emotional variability and suicidal ideation and examined the moderating role of parent-adolescent connectedness.

Methods: Participants included 108 Taiwanese late adolescents (Mage = 18.53, SDage = 0.39; 64% female) who completed ecological momentary assessment (EMA) over 14 days, and baseline and follow-up assessments over 6 months.

Results: Results indicated that while negative emotional (NE) and positive emotional (PE) variability were not associated with suicidal ideation at baseline, both predicted increased suicidal ideation 6 months later. Furthermore, parent-adolescent connectedness moderated the relationship between NE variability and suicidal ideation, with high connectedness mitigating the adverse effects of NE variability.

Conclusions: These findings suggest that emotional variability is a key predictor for the development of suicidal ideation and highlight the protective role of parent-adolescent connectedness. Interventions promoting family connectedness may be effective in reducing suicidal risk among emotionally variable youth.

Background: Firearms are the leading means of suicide in the United States. Research on those who survive injuries associated with intentional self-harm gunshot wounds (GSWs) is limited.

Aims: This study explores differences between patients and injury/event characteristics of cases involving nonfatal intentional self-harm GSWs compared to control cases that sustained nonfatal GSWs that did not involve intentional self-harm.

Method: Analyses used multivariable logistic regression using the Firearm Injury Surveillance Study data (1993-2021). The complex survey structure of the data was accounted for in analysis, producing nationally representative estimates.

Results: There were an estimated 113,012 (95% CI: [53,807.58, 172,216]) nonfatal intentional self-harm GSW injuries seen in U.S. emergency departments between 1993 and 2021, with differences in adjusted odds ratios across sex and incident characteristics. Intentional self-harm shootings were estimated to have an 84% (95% CI: [76.5, 94.1]) case fatality rate. Each year, an estimated average of 3897 patients survive intentional self-harm GSWs in the United States.

Conclusion: Survival of intentional self-harm GSWs is a rare, but nonzero outcome that merits further study.

Background: One mainstay of psychiatric treatment for suicidal crises is inpatient psychiatric hospitalization. Despite the need to secure immediate safety and stabilization, inpatient treatment for acutely suicidal patients remains diagnosis-specific, which may fail to directly target and adequately manage suicidal behavior as a symptom and reason for admission or treatment. The post-discharge period is a high-risk period for repeat suicide attempts or death by suicide, but overburdened workforce and high patient turnover make it difficult to provide suicide-specific treatment.

Methods: In response to this need, we developed the Suicide Prevention Inpatient Group Treatment (SPIGT), a four-module, group-based intervention, which provides evidence-supported concrete tools and psychoeducation to directly address suicidality. To assess feasibility and acceptability of implementation, the SPIGT was piloted on an inpatient psychiatric unit starting in 2016. Group participants were given optional, anonymous surveys after each module. Unit clinicians also completed optional, anonymous surveys to assess their attitudes towards the intervention.

Results: Results indicate that participants responded very favorably to each module, and that unit clinicians felt that the implementation of this intervention was feasible and acceptable.

Conclusion: The SPIGT shows promise as a scalable suicide-specific, brief intervention, which addresses an unmet and critical need in suicide prevention.

Introduction: As an important transdiagnostic factor, intolerance of uncertainty (IU) can predict suicidal ideation (SI). But little is known about the underlying mechanisms. The present study examined the chain mediating roles of three maladaptive cognitive emotion regulation (CER) strategies and psychache in the relation between IU and SI, as well as gender differences.

Methods: A number of 1532 Chinese adolescents (43.1% males; baseline mean age = 15.00 years, SD = 1.57) completed self-report questionnaires on IU, self-blame, rumination, catastrophizing, psychache and SI for two waves, 6 months apart.

Results: The results indicated that IU predicted SI through psychache and the serial mediation of the three maladaptive CER strategies and psychache, but IU did not predict SI through the three maladaptive CER strategies. The relation between IU and catastrophizing, the relation between catastrophizing and psychache, and the relation between psychache and SI were stronger among females than males.

Conclusion: The results advance our understanding of how IU predicts SI, highlighting the importance of psychache in the development of SI.

Introduction: One factor that can influence whether someone will engage in secure firearm storage is having a suicide exposure (SE). Daruwala et al. (2018) examined this and found that individuals with an SE, without considering perceived closeness, did not significantly differ from those who did not have an SE in their firearm storage practices. Thus, the present study aimed to replicate and extend the research of Daruwala et al. (2018) by examining if the method of suicide (by firearm or other means) and closeness of suicide decedent relate to secure firearm storage practices.

Methods: 308 male firearm owners completed self-report measures assessing SE, perceived closeness to decedent, and current firearm storage practices. Chi square and logistic regression analyses were conducted.

Results: Suicide loss exposure, regardless of method used in suicide, did not relate to firearm storage practices in this sample. We also found that there was no association between perceived closeness to the decedent who died by suicide by firearm and secure storage, without considering age.

Conclusions: Results underscore the difficulty in helping male firearm owners develop personally salient reasons to increase safety with firearms. Implications for clinical care, firearm safety, and public health initiatives are explored.

Introduction: Suicidal thoughts and behaviors often onset during adolescence, constituting a major public health concern. Despite rising rates in youth, psychotherapeutic and pharmacological treatment outcomes remain meager, indicating a need to identify modifiable risk factors. Experts suggest sleep may serve as a promising clinical indicator of risk and treatment progress, yet few studies have examined acute temporal associations between sleep and suicidal ideation.

Methods: Participants were depressed and suicidal adolescents (age 13-19, n = 311) attending an intensive outpatient program (IOP). Patients completed weekly self-report assessments of sleep, depression, and suicidal ideation throughout IOP, with an average of 5 assessments over 30 days.

Results: Greater overall sleep difficulties, as well as within-person increases in sleep difficulties, were predictive of greater depression severity and suicidal ideation at subsequent assessments, above and beyond previous levels of symptoms. The reverse associations were not found. Inclusion of within-person changes in sleep difficulties significantly improved model fit compared to inclusion of overall sleep difficulties alone.

Discussion: This study provides additional evidence for a prospective relationship between worsening sleep difficulties and suicidal ideation in an IOP youth sample. Worsening sleep may be an important clinical indicator of subsequent depression and suicide risk among adolescents in treatment.

Background: The interpersonal-psychological theory of suicidal behavior (IPTSB) is widely applied to explain non-fatal suicide behaviors, but yet to be tested empirically with a Ghanaian sample.

Aims: Using a total of 800 junior high school students (JHS) in the Greater Accra Region of Ghana, this study tests the utility of the IPTSB with the aim of having a better understanding of how suicide behavior is occurring among this young generation of Ghanaians.

Materials and methods: The study used the WHO-CIDI's self-reported measures on suicide behavior and the Interpersonal needs questionnaire, which measures the elements of the IPTSB. Structural equation modeling was performed using Mplus to test the overall fit of the model as well as associations among the predictor variables and outcome variables.

Results: The study found the IPTSB was significant for explaining 12-month and lifetime suicide behaviors in the sample. Also, 12-month suicide attempt was significantly associated with increased 12-month suicide ideation, increased acquired capability and increased perceived burdensomeness. In addition, 12-month suicide ideation was significantly associated with increased thwarted belongingness and increased perceived burdensomeness.

Discussion and conclusion: This study provides new information for clinicians and policy makers working to reduce suicide behavior among Ghanaian adolescents.
