Suicide and Life-Threatening Behavior最新文献

Introduction: Perceived responsiveness, or the extent to which one feels understood, validated and cared for by close others, plays a crucial role in people's well-being. Can this interpersonal process also protect people at risk? We assessed whether fluctuations in suicidal ideation were associated with fluctuations in the degree of perceived responsiveness that psychiatric patients (admitted in the context of suicide or indicating suicidal ideation) experienced in daily interactions immediately after discharge.

Methods: Fifty-seven patients reported on suicidal ideation (5 times a day) and perceived responsiveness (daily) for four consecutive weeks. The effects of established risk factors-thwarted belongingness, perceived burdensomeness, and hopelessness-were assessed as well.

Results: The more patients felt that close others had been responsive to them, the less suicidal ideation they reported. At low levels of thwarted belongingness, perceived burdensomeness, or hopelessness, perceived responsiveness seemed to play a protective role, negatively co-occurring with suicidal ideation. When thwarted belongingness, perceived burdensomeness, and hopelessness were high, perceived responsiveness did not have an effect.

Conclusion: Perceived responsiveness could be a protective factor for suicidal ideation for people at risk only when they are experiencing low levels of negative perceptions. When experiencing highly negative perceptions, however, perceived responsiveness seems to matter less.

Introduction: The US Department of Defense recommends lethal means safety counseling (LMSC) to promote firearm injury prevention via secure storage of personal firearms. We describe the rollout of a universal, peer-delivered adaptation of Project Safe Guard (PSG)-a brief, single-session LMSC discussion-at a US Space Force installation.

Method: Program evaluation data were collected via anonymous, voluntary, and online surveys. Of approximately 862 eligible active-duty service members and embedded civilians, 324 completed the preprogram survey and 68 and 37 completed the 1- and 2-month follow-ups, respectively.

Results: At preprogram, 69.1% agreed that peer-delivered LMSC is appropriate. After rollout, 100% of the 222 firearm locking devices available to service members were requested from the on-base Violence Prevention Integrator. The effectiveness of PSG was indeterminable due to the low survey response rates.

Conclusions: Despite strong preprogram support for peer-delivered LMSC and behavioral indicators of secure firearm storage (e.g., firearm locking device requests), several challenges limited the uptake and evaluability of the PSG program in this naturalistic environment, including military survey fatigue and competing mission priorities. Additional work is needed to determine the effectiveness of peer-delivered LMSC in a military context. Sustained base support and military-civilian collaborations will be critical.

Introduction: Suicide loss survivors can provide information not otherwise available about the circumstances preceding a suicide. In this study, we analyzed interview data from suicide loss survivors collected as part of a psychological autopsy study of U.S. Army soldiers.

Methods: Next-of-kin (NOK) (n = 61) and Army supervisors (SUP) (n = 107) of suicide decedents (n = 135) who had died in the last 2-3 months answered open-ended questions about suicide risk factors, ideas for improving suicide prevention, and the impact of the suicide. Responses were coded using conventional content analysis methods to identify common themes.

Results: Many NOK (30%) and SUP (50%) did not observe any signs of risk preceding the soldier's suicide. The most common idea regarding suicide prevention from SUP was that the suicide was inevitable, whereas NOK were more likely to emphasize the importance of increasing mental health treatment and reducing stigma. Both NOK and SUP reported negative effects of the suicide, but SUP reported some positive effects (e.g., increased unit connectedness).

Conclusions: Results underscore the challenges of using informants to identify soldiers at high risk of suicide, given many respondents did not observe any warning signs. Findings also highlight attitudinal barriers present in the military that, if targeted, may increase soldiers' help-seeking and willingness to disclose their risk.

Introduction: The Virtual Hope Box (VHB) mobile application is an adapted version of the conventional hope box intervention that is used in several evidence-based treatments for suicide behaviors. The VHB is an award-winning app developed by a collaboration between the Departments of Defense and Veterans Affairs. Multiple studies have assessed the utility and effectiveness of the VHB for use in suicide prevention, but no reviews of the literature have been conducted.

Methods: Authors performed a review of the literature using PsycINFO, EBSCOhost, and PubMed. 15 articles were ultimately included.

Results: Results were categorized into three areas: (1) efficacy and effectiveness, (2) feasibility, awareness, and usage in high-risk populations, and (3) implementation approaches to increase use among patients and providers. Existing evidence for the VHB supports its feasibility and acceptability, especially among military and veteran populations. Only one study investigated effectiveness in a randomized control trial. Although the VHB developers have disseminated the app nationally, low adoption rates among veteran patients and VA providers remain. Studies found that educational implementation strategies can improve utilization rates.

Conclusions: Future research should examine suicide behaviors as outcomes, approaches to incorporating the VHB into treatment, and a range of populations.

Introduction: Suicide rates are higher in prison than in the general population in most countries. The proximity of some suicides to prison events has only received little attention in comparative studies. The aim of this study was to assess the relationship between suicide and four prison events: conviction, disciplinary solitary confinement, nondisciplinary solitary confinement and inter-prison transfer, in a national retrospective cohort study of people in prison.

Methods: All incarcerations in France that occurred during 2017-2020 were eligible. Data were collected from an administrative database of the National Prison Service. Survival bivariate and multivariate analyses were performed with a Cox regression model.

Results: Of 358,522 incarcerations were included, among which 469,348 events and 449 suicides occurred. In multivariate analysis, suicide risk was higher the first day of disciplinary solitary confinement (HR = 42.1 [21.5-82.7] and HR = 119.0 [71.5-197.9], before and after a government decree on the disciplinary system, respectively. It was higher within 2 weeks after a transfer (HR = 3.5 [2.3-5.2])) or entry in nondisciplinary solitary confinement (HR = 6.7 [3.4-13.3]) and lower within 2 weeks after a conviction (HR = 0.6 [0.4-1.0]).

Conclusion: Solitary confinement and transfer were found to be precipitating factors of suicide in people who are incarcerated. These results offer interesting perspectives on prevention.

Introduction: This study aimed to investigate the association between handgrip strength and suicidal ideation in representative samples of adults aged ≥50 years from six LMICs (China, Ghana, India, Mexico, Russia, and South Africa).

Methods: Cross-sectional, community-based data from the World Health Organization's Study on Global Aging and Adult Health were analyzed. Handgrip strength quintiles by sex were created based on the average value of two handgrip measurements of the dominant hand. Self-reported information on past 12-month suicidal ideation was collected. Multivariable logistic regression analysis was conducted to assess associations.

Results: Data on 34,129 individuals were analyzed [mean (SD) age 62.4 (16.0) years; age range 50-114 years; 52.1% females]. After adjustment for potential confounders, in the overall sample, compared to the handgrip strength quintile with the highest values [Quintile 1 (Q1)], Q2, Q3, Q4, and Q5 were associated with significant 2.15 (95% CI = 1.05-4.39), 2.78 (95% CI = 1.06-7.32), 3.53 (95% CI = 1.68-7.42), and 6.79 (95% CI = 2.80-16.48) times higher odds for suicidal ideation.

Conclusions: Lower handgrip strength was significantly and dose-dependently associated with higher odds for suicidal ideation in adults aged ≥50 years from LMICs. Future longitudinal studies are needed to understand the underlying mechanisms, and whether increasing general muscular strength and physical function may lead to reduction in suicidal ideation.

Background: According to the integrated motivational-volitional model of suicide, feelings of entrapment are related to the emergence of suicidal ideation (SI). However, this relation can be moderated by certain protective factors.

Methods: This study examined whether aspects of psychological flexibility (i.e., experiential avoidance, experiential acceptance, harnessing) moderated the relation between aspects of entrapment and SI severity in college students experiencing SI (N = 553) both cross-sectionally and when SI severity was measured 1 week later (N = 247).

Results: At baseline, experiential acceptance, but not experiential avoidance or harnessing, significantly moderated the relation between external entrapment and SI severity and internal entrapment and SI severity. No aspects of psychological flexibility prospectively moderated relations between entrapment and SI severity.

Conclusions: Aspects of psychological flexibility may influence immediate vulnerability to SI severity among young adults experiencing feelings of entrapment. Implications for clinical interventions influencing changes in psychological flexibility are discussed.

Introduction: Non-suicidal self-injury (NSSI) is a highly prevalent maladaptive behavior, often used to cope with intense negative affect. Rumination is an emotion regulation strategy that leads to fixation on and exacerbation of (typically) negative affective states. However, studies examining the relationship between rumination and NSSI have yielded mixed results, showing high degrees of heterogeneity.

Methods: The present study conducted meta-analyses (k = 50) of the association between overall rumination and NSSI, and independent meta-analyses for each of four subtypes of rumination (general, depressive, brooding, reflection rumination). Potential moderators that may influence the magnitude of these relationships were also examined.

Results: A small-to-moderate positive association between rumination and NSSI was found independent of rumination subtype. Moderating effects included NSSI outcome measure and study design for overall rumination and general rumination, respectively. Race was found to moderate the relationships between both brooding and depressive rumination and NSSI, though in inverse directions. An analysis of effect heterogeneity across studies suggested that undetected moderators may be present.

Conclusion: Results of this study support the relationships between rumination subtypes and NSSI and identify factors that may impact these relationships. Continued research is needed to understand this association, particularly in more varied subtypes of rumination and cognitive-affective moderators.

Introduction: Parents and adolescents are often discrepant in their reports of adolescent psychosocial factors. Few studies have addressed parent-adolescent discrepancies in subjective ratings of familial dysfunction and depression as longitudinal predictor variables, and none have done so in a treatment setting for adolescents with acute suicidality. This study examined how parent-adolescent discrepancies in familial dysfunction and depression impact adolescent treatment response in an intensive outpatient program for suicidality.

Methods: Adolescents (N = 315) were assessed at treatment entry and exit for familial dysfunction, depression, and suicidal ideation. Parents received parallel assessments of familial dysfunction and adolescent depression at each time point. A polynomial regression was conducted to determine whether parent-adolescent discrepancies in reports of familial dysfunction and depression at entry related to the treatment outcome of adolescent-reported depression and suicide ideation at exit.

Results: Significant discrepancies were present with on average adolescents reporting more depression and familial dysfunction than parents. Entry discrepancy in familial dysfunction (but not depression) predicted suicide ideation at exit.

Conclusions: Our results suggest that parent-adolescent discrepancies in perception of familial dysfunction is a risk factor for poor outcomes in suicidal youth and might be a fruitful target in treatment programs.

Introduction: This study aimed to analyze the real-time variability of suicidal ideation intensity and the relationship between real-time and retrospective reports of suicidal ideation made on the Beck Scale for Suicidal Ideation (BSS), among young people with borderline personality disorder (BPD).

Methods: Young people (15-25-year olds) with BPD (N = 46), recruited from two government-funded mental health services, rated the intensity of their suicidal ideation six times per day for 7 days before completing the BSS.

Results: For 70% of participants, suicidal ideation changed in intensity approximately five times across the week, both within and between days. BSS ratings were most highly correlated with the highest real-time ratings of suicidal ideation. However, this was not significantly different from the relationship between the BSS and both the average and most recent ratings. Median ratings of suicidal ideation intensity were higher on the BSS compared with an equivalent question asked in real time.

Conclusion: Findings suggest that young people with BPD experience high levels of fluctuation in their intensity of suicidal ideation across a week and that retrospective reports of suicidal ideation might be more reflective of the most intense experience of suicidal ideation across the week.
