Suicide and Life-Threatening Behavior最新文献

Introduction: The objective of this study was to compare jealousy as a correlate of intimate partner homicide-suicide cases to homicide-only cases using data from the National Violent Death Reporting System (NVDRS), a state-based surveillance system maintained by the Centers for Disease Control and Prevention. Jealousy is categorized as jealous feelings or distress over a current or former intimate partner's relationship or suspected relationship with another person.

Methods: NVDRS data from a 5-year period (2016-2020) was used to estimate frequencies and identify significant differences in jealousy and other sociodemographic, mental health, relationship, and incident-related correlates of intimate partner homicide-suicide compared to homicide-only cases. Cases were included if they involved an intimate partner single homicide or a single homicide followed by suicide.

Results: The study sample included 5335 cases (intimate partner homicide-suicide n = 1402; homicide-only n = 3933). A significantly higher percentage of intimate partner homicide-suicide cases reported jealousy preceding the event (9%) compared to homicide-only cases (6%). Compared with homicide-only cases, homicide-suicide cases had 3.5 greater odds of recording jealousy as a precipitating event.

Conclusion: Findings suggest that intimate partner homicide-suicide cases are distinct from homicide-only cases both in terms of individual- and incident-level and situational factors, including the presence of jealousy.

Objective: Inpatient suicide remains difficult to predict. This study aimed to identify individual patient predictors to help identify those at greater risk.

Methods: This case-control study was undertaken in an independent mental health service in Ireland. Cases were drawn from all admissions to the service between March 2004 and February 2019. Controls were matched for date of admission. Univariate and multivariate analyses were conducted.

Results: Thirty-three cases of inpatient suicide were compared to 132 controls. The inpatient suicide rate was 76.2 per 100,000 admissions. The rate of inpatient suicide fell in line with national rates despite less restrictive practices being implemented in the service. Males accounted for 66% of cases. Hanging was the most common method of suicide overall and among male patients, and drowning was the most common among females. Male gender, tertiary referral, an adverse psychosocial event during admission, a period of absence without leave and expressing hopelessness were identified as independent risk factors for inpatient suicide. Substance use, involuntary detention, family history of suicide, and number of previous admissions were not significant.

Conclusions: While not highly sensitive, a period of absence without leave, tertiary referral and hopelessness are important predictors of inpatient suicide risk that treating teams should consider in care planning.

Introduction: Adolescent suicidal ideation (SI) and non-suicidal self-injury (NSSI) are crucial public health issues, yet their co-developmental trajectories during early adolescence and their associations with predictors and outcomes are unclear. This study aimed to (a) identify heterogeneous co-developmental trajectories of SI and NSSI, (b) explore associations between transdiagnostic predictors and trajectories, and (c) assess suicide attempt risk across trajectories.

Methods: Four hundred fifty-three adolescents (M_age = 12.35 years, 48.3% boys) completed surveys at 6-month intervals across 2 years. At Time 1 (Nov 2020), participants completed surveys encompassing SI, and NSSI, along with family, peer, and individual predictors. Subsequent surveys (Times 2-4) measured SI and NSSI, with suicide attempts queried at Time 4.

Results: Parallel process latent class growth models revealed three co-developmental groups (i.e., Stable low NSSI and SI; Moderate-NSSI and high-SI, parallel decreasing; High-NSSI and moderate-SI, parallel increasing). Multivariate logistic regression indicated that group membership was predicted by parental rejection, parental warmth, bullying victimization, depressive and anxiety symptoms, thwarted belongingness, and perceived burdensomeness. Adolescents in the "High-NSSI and moderate-SI, parallel increasing" group reported the highest suicide attempt frequency.

Conclusion: These findings underscore subgroup distinctions and transdiagnostic predictors in comprehending SI and NSSI progression, emphasizing the necessity of dynamic monitoring and tailored interventions for distinct subgroup characteristics.

Introduction: Resting heart rate has been distinctly related to both internalizing (high pulse) and externalizing (low pulse) disorders. We aimed to explore the associations between resting heart rate and suicidal behavior (nonfatal suicide attempt [SA] and suicide death [SD]) and evaluate if such associations exist beyond the effects of internalizing/externalizing symptomatology.

Method: We used Cox proportional hazards models to evaluate the associations between resting heart rate (age 19) and later SA/SD in 357,290 Swedish men. Models were controlled for internalizing disorders, externalizing disorders, and resilience (the ability to deal with adversity). Co-relative analysis (comparing pairs of different genetic relatedness) was used to control for unmeasured family confounders and improve causal inference.

Results: In baseline models, low resting heart rate was associated with SA (HR = 0.96; 95% CI: 0.95,0.98) and high resting heart rate with SD (HR = 1.04; 95% CI: 1.002,1.07). The association with SA remained after adjustment for all confounders (HR = 0.98). However, the association with SD did not persist after controlling for covariates. Co-relative analysis did not support causal associations.

Conclusions: Our findings raise interesting etiological questions for the understanding of suicidal behaviors but do not support the usefulness of resting heart rate in suicide prediction.

Introduction: While suicides in the United States decreased during the COVID-19 pandemic, statistically significant decreases have been limited to White people throughout a large portion of 2020.

Methods: This paper outlines possible explanations for racial/ethnic differences in suicidality in the early pandemic phases.

Results: We propose both distal (i.e., tele-mental health usage, internet and technology access, employment protections, and economic security) and proximal (cultural beliefs, coping strategies, clustering, pulling together, and embracing life) factors that may have helped build and foster community and mental wellness. However, this paper argues these factors did not extend, or did not extend as much, to many communities of color.

Conclusions: We argue that these disparities are due to the myriad effects of discrimination and systemic racism, encapsulated broadly by the minority stress theory, and provide suggestions for relief and research.

Introduction: Prior research has established individuals living in cultures of honor to be at higher risk for suicide. However, research has yet to examine how emotion regulation may play a role in explaining this link. The current research intended to address if those who endorse honor norms, who are keen to protect their reputation, might engage in emotional suppression as a way to avoid being seen as weak, thus heightening their risk for suicide.

Method: Data were collected using a survey design across three studies (total N = 988). Studies 1 and 2 were cross-sectional designs with MTurk and undergraduate samples. Study 3 was conducted longitudinally using CloudResearch.

Results: Results demonstrated those higher in honor endorsement engage in emotional suppression to avoid being seen as weak (Study 1), that emotional suppression and subsequent depression indirectly explain the relationship between honor endorsement and suicide attempts (Study 2), and that relationships between honor endorsement and changes in suicidal ideation are explained by emotional suppression and depressive symptomology (Study 3).

Conclusion: Findings provide needed insight into the daily emotional experiences of honor endorsers and how it may influence suicidality, providing a point of entry for clinicians to construct meaningful honor-oriented intervention programs.

Introduction: Fatality review is a public health approach designed to inform efforts to prevent fatalities of a certain kind (e.g., suicide, homicide) or in a specific setting or population (e.g., hospitals, youth). Despite extensive literature on fatality review generally, the literature on suicide review teams specifically is scant. The aim of this paper is to: describe the implementation of a local adult suicide review commission, detail examples of initial outcomes and recommendations developed by the commission, and provide recommendations and/or best practices for how to develop and implement an adult suicide review team.

Methods: We utilize framing questions from the American Association of Suicidology's psychological autopsy framework. By using these guiding questions in the discussion, members are invited to explore not only the stressors that may have more immediately preceded the suicide event itself, but to situate those stressors in the context of the individual's life course.

Results: Several recommendations proposed by our commission have resulted in tangible outcomes and are detailed using Haddon's Matrix as a guiding prevention planning tool.

Implications: We have highlighted the need to move beyond looking at individual-level help-seeking to focus on structural/systemic issues that result in stress or create unsafe environments for at-risk individuals.

Introduction: Deficits in neurocognition and social-cognition have been suggested to be an endophenotype for suicidal behavior. We aimed to compare the social-cognition and neurocognitive characteristics of adolescents diagnosed with depression with and without suicidal behavior and to investigate whether these functions predict suicide.

Method: Adolescents diagnosed with Major Depressive Disorder (MDD) with suicidal behavior (n = 42); MDD without suicidal behavior (n = 44) and age- and sex-matched controls (n = 43) were included. The University of Pennsylvania Computerized Neurobehavioral Test Battery and Autism Spectrum Screening Questionnaire (ASSQ) were used to evaluate social-cognition and neurocognitive characteristics.

Results: Several neurocognitive domain values of MDD groups, were significantly different from the control group. Neutral emotion recognition task (p = 0.025) and ASSQ scores were found to be significantly impaired in the patient groups (p < 0.001). Logistic regression analysis showed that, only the increase in the Suicide Probability Scale score was found to be significant as a risk factor predicting suicide (p = 0.007, OR: 1.246).

Conclusion: While the neurocognitive and social-cognitive performances of adolescents with MDD were significantly lower than the control group, these performances in the two depression groups were similar. When the predictors of suicidal behavior were examined, it was found that only the increase in suicidal ideation scores predicted suicide.

Objectives: Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk.

Method: An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days.

Results: Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge.

Conclusions: Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.
