Identifying latent classes of suicidal ambivalence: Associations with suicide risk correlates and outcomes.

INTRODUCTION: Research has largely conceptualized suicidal ambivalence as the difference between one's wish to live and wish to die without fully considering other suicide ideation (SI) experiences included on measures like the Beck Scale for Suicide Ideation (BSS). We utilized BSS items to identify SI latent classes and examined relevant correlates and outcomes. METHODS: We collected self-report data from two samples of US adults who: (1) self-identified as LGBTQ+ (N = 349; cross-sectional) and (2) self-reported past-week SI (BSS score ≥ 11; N = 133; 3 timepoints). RESULTS: Latent class analyses supported three-class (Sample 1) and four-class solutions (Sample 2), which included ambivalent classes. In Sample 1, sexual orientation, gender, depression, anxiety, SI, and suicide-specific rumination were concurrently associated with class membership. In Sample 2, depression, SI, suicide-specific rumination, and physical/psychological distance from suicide methods were concurrently associated with class membership. In Sample 2, at both follow-ups, suicide plans/preparations and Acute Suicidal Affective Disturbance symptom frequencies were provided by class membership, and suicidal intent significantly differed by class membership. CONCLUSIONS: SI classes differed by sample and evidenced nuances in SI and suicidal ambivalence. Risk factors and suicide-related outcomes also differed by class membership. Implications and limitations are discussed.

Determining the MMPI-3 SUI scale's cross-sectional and prospective utility in suicide risk assessment.

OBJECTIVE: In-depth suicide risk assessments are particularly important to long-term suicide prevention. Broadband measures of psychopathology, such as the Minnesota Multiphasic Personality Inventory (MMPI) instruments, assess suicide risk factors and various mental health comorbidities. With the recent release of the MMPI-3, the Suicidal/Death Ideation (SUI) scale underwent revisions to improve its construct validity and detection of suicide risk factors. Thus, we hypothesized the MMPI-3 SUI scale would demonstrate medium to large associations with suicidal experience and behaviors, future ideation, and interpersonal risk factors of suicide. METHODS: A sample of 124 college students screened for elevated depressive symptoms completed a brief longitudinal study. Participants completed a baseline session including the MMPI-3 and criterion measures and three brief follow-ups every 2 weeks. RESULTS: SUI scores were most robustly associated with increased risk for past suicidal ideation, planning, and perceived burdensomeness. Prospectively assessed suicidal ideation was also meaningfully associated with SUI. SUI scale elevations indicate an increased risk of suicide-related risk factors. CONCLUSION: The MMPI-3 is a valuable tool to inform long-term suicide prevention for those experiencing elevated depressive symptoms as the SUI scale can assess past, current, and future suicide-related risk factors, including suicidal ideation and behaviors.

A comparison of retrospectively reported and ecological momentary assessment-reported perceived social support in predicting ecological momentary assessment-reported non-suicidal self-injury.

INTRODUCTION: Non-suicidal self-injury (NSSI) urges and behaviors are associated with lower perceived social support and related constructs (e.g., perceived rejection). However, no studies have examined the concordance of retrospective (baseline) and ecological momentary assessment (EMA) perceived social support assessments. Retrospective and EMA reports are often only weakly to moderately correlated; measurement approaches may, therefore, impact observed associations between variables. We tested whether average EMA-reported perceived emotional social support uniquely predicts EMA-reported NSSI urges and behaviors above baseline-reported retrospective self-report of perceived emotional social support alone. METHODS: 93 young adults (ages 18-34) with past-month NSSI urges or behaviors and lifetime NSSI behaviors completed a semi-structured interview, self-report surveys, and a 2-week EMA protocol. RESULTS: Baseline- and EMA-reported perceived emotional social support were positively correlated (Kendall's tau-b = 0.51). Average EMA-reported social support was uniquely associated with EMA-reported NSSI urges but not NSSI behaviors. CONCLUSIONS: EMA-reported perceived emotional social support captured information not represented by baseline reports alone, but improvement in model fit was modest. EMA-reported social support may further improve the estimation of EMA-reported NSSI urges if modeled as a proximal predictor of NSSI. Further work is needed to clarify temporal directions between social support and NSSI urges. Limitations are discussed.

A Psychometric Evaluation of the Interpersonal Hopelessness Scale Among Individuals With Elevated Suicide Risk.

The interpersonal theory of suicide hypothesizes that suicide ideation (SI) emerges specifically in the context of hopelessness about the immutability of thwarted belongingness (TB) and perceived burdensomeness (PB; i.e., interpersonal hopelessness). The psychometrics of the Interpersonal Hopelessness Scale (IHS), which could be used to test this hypothesis directly, have not been rigorously evaluated. Participants (U.S. adults reporting past-year SI) completed online self-report assessments at Waves 1 (W1; N = 595) and 2 (W2; N = 215), 1 week apart. Confirmatory factor analyses supported a two-factor structure, IHS-TB and IHS-PB. Correlations indicated strong concurrent validity. Hurdle negative binomial regressions indicated that W1 IHS-TB and IHS-PB scores were associated with SI presence and severity at both waves, but this was inconsistent when adjusting for other W1 variables. IHS-TB and IHS-PB demonstrated excellent internal consistency and moderate to good test-retest reliability. The IHS could improve theory testing and suicide risk assessment and management.

Screening Utility of the PHQ-2 and PHQ-9 for Depression in College Students: Relationships with Substantive Scales of the MMPI-3.

We investigated the validity and screening effectiveness of the PHQ-2 and PHQ-9 scores in 229 college students in a cross-sectional design. PHQ associations with Minnesota Multiphasic Personality Inventory-3 internalizing scales suggest PHQ scores are effective screening tools for college students and may aid in effective triage and service needs.

Examination of real-time variation in interpersonal hopelessness and suicidal desire in a college student sample reporting past-2-week suicidal ideation.

INTRODUCTION: Interpersonal hopelessness (IH), as outlined in the Interpersonal Theory of Suicide, is theorized to include two correlated, distinct constructs: hopelessness about one's thwarted belongingness (IH-TB) and about perceived burdensomeness on others (IH-PB). Few studies have explored IH, and none have explored its temporal stability or prospective prediction of suicidal desire. METHODS: Undergraduates (N = 43) selectively recruited for past-2-week suicidal ideation completed five ecological momentary assessment surveys per day for 10-days. Intraclass correlations, root mean square of successive differences, and multilevel models were used to examine the data and test relationships among predictor variables. RESULTS: IH-TB and IH-PB demonstrated greater temporal stability than general hopelessness. IH-TB, IH-PB, and their interaction were significant predictors of suicidal desire concurrently and prospectively. IH-PB was no longer significantly predictive of suicidal desire when adjusting for general hopelessness. Post-hoc models showed that suicidal desire was not predictive of IH-TB, IH-PB, or their interaction suggesting the relationship is not recursive. CONCLUSION: Results showed that interventions aimed at decreasing one's hopelessness specific to TB and PB may be beneficial for decreasing suicidal desire. Future research should seek to replicate these results in larger and more diverse samples and consider the use of shorter ambulatory assessment intervals.

Integrating the interpersonal theory of suicide and the dualistic model of passion among adults at risk for suicide.

The dualistic model of passion proposes two passion types, harmonious and obsessive, representing adaptive and maladaptive passion, respectively. Studies suggest interpersonal experiences explain harmonious passion benefits and obsessive passion negative consequences. However, research has not examined passion among individuals with clinically elevated suicide risk, nor the associations between passion types and suicide-related outcomes. The present study presents a conceptual model linking the dualistic model of passion and the interpersonal theory of suicide constructs [specifically, thwarted belongingness (TB) and perceived burdensomeness (PB)]. U.S. adults with clinically elevated suicide risk (N = 484) completed online, cross-sectional assessments of harmonious and obsessive passion, TB, PB, and future dispositions (i.e., positive focus, negative focus, and suicide orientation). A mediation model indicated the effects of harmonious and obsessive passion on positive and negative focus and suicide orientation were largely explained by TB and PB. The present findings suggest engaging in a passion activity may be meaningfully related to suicide-related interpersonal perceptions (i.e., TB and PB).

Anterior Hook Plating of Patella Fractures: A Biomechanical Analysis and Clinical Series.

OBJECTIVES: To compare anterior hook plating with established fixation constructs biomechanically and report outcomes and complications in a cohort of patella fractures treated with the technique. DESIGN: Laboratory-based biomechanical study and clinical multicenter retrospective cohort study. SETTING: 2 US Level 1 trauma centers. PATIENTS/PARTICIPANTS: 51 patients (28 M and 23 F) with 30 simple transverse and 21 comminuted patella fractures. Thirty-six cadaveric patellae were used for the biomechanical study. INTERVENTION: Biomechanical-dorsal plating was compared with cerclage wiring and modified tension band cable fixation in a comminuted patella fracture model in 36 cadaveric patellae. Constructs were tested at 0° and 45 degrees of flexion. Clinical-we reviewed a consecutive series of patella fractures in 2 centers for outcome and complications. MAIN OUTCOME MEASUREMENTS: Biomechanical-construct stiffness. Clinical-reduction, union, complications, and range of motion. RESULTS: Stiffness was greatest in dorsal plating at both 0° and 45 degrees. Dorsal plating (976 N, 1643 N) > modified tension band (317 N, 297 N) > cerclage (89.8 N, 150.3 N) at 0 and 45 degrees, respectively. 51 patients with patella fractures had them fixed with dorsal 2.7-mm mini fragment plates including a distal to proximal lag screw through the plate from the nose of the patella. 9 cases were small distal fragments not easily managed with screws and cables. All patients were followed up to union. There were 2 infections (1 superficial and 1 deep with nonunion), and 5 had implant removal (9.8%). CONCLUSIONS: Dorsal plating is biomechanically and clinically superior to modified tension band and cerclage techniques in comminuted patella fractures. This method allows for fixation of small distal pole fractures. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Association between perceived social support and suicide ideation distress among psychiatric inpatients: The role of thwarted interpersonal needs.

INTRODUCTION: The interpersonal theory of suicide posits that thwarted belongingness (TB) and perceived burdensomeness (PB) are proximal risk factors for suicide ideation; however, there are mixed results regarding this hypothesis among psychiatric inpatients. OBJECTIVE: The current study examined the mediating role of TB and PB in the relationship between perceived social support (i.e., support from family, friends, a significant other, and total) and suicide ideation distress among psychiatric inpatients. METHODS: Participants (short-term psychiatric inpatients; N = 139) were administered self-report assessments cross-sectionally. RESULTS: Nonparametric mediation results indicated that the total (additive) indirect effects of TB and PB, in parallel, were significant in all models, yet there were only significant specific (unique) indirect effects of PB. CONCLUSION: TB and PB, in combination, may be proximal risk factors for suicide ideation distress among psychiatric inpatients with lower perceived social support from family, friends, a significant other, and in total. These findings are congruent with the interpersonal theory of suicide's propositions that the combination of TB and PB increases the risk for suicide ideation. Clinicians may consider using interventions that target increasing perceived social support and decreasing TB and PB (i.e., cognitive behavioral therapy and social skills training) for this population.

Perceptions of grief reactions in family members of incarcerated individuals: A vignette-based experiment.

We examined perceptions of individuals grieving the loss of a family member to incarceration. Participants (N = 1095) were randomized to a vignette that varied by race-ethnicity, crime type, and grief trajectory to assess their perceptions. Results indicated: (1) participants perceived prolonged grief as less appropriate than resilience; (2) Black family members grieving someone who committed a violent crime as more appropriate compared to White family members; and (3) women endorsed both grief trajectories as more appropriate and indicated greater comfort supporting the family member. Lastly, participants indicated prolonged, White and Latinx grievers should seek therapy more than resilient or Black individuals.

Depressive Symptoms Moderate the Association Between the Recent History of Alcohol Use Severity and Suicide Attempt History Among Adults in a Pretrial Jail Diversion Program.

Background: Justice-involved individuals are at elevated risk for suicidal behavior; however, research examining risk for suicidal behavior in pretrial jail diversion programs (pretrial diversion) is limited. Aims: We aimed to test (1) associations between depressive symptoms and alcohol and drug use, and suicide attempt history (SAH), and (2) interactions between depressive symptoms and alcohol and drug use in relation to SAH among adults in an urban pretrial jail diversion program. Method: The design was cross-sectional, including self-report assessments and file reviews of historical information. Adults (N = 274; Mage = 33.72; 73.7% men; 52.6% non-Hispanic Black) completed assessments within two weeks of beginning the pretrial program. Results: Depressive symptoms were positively associated with SAH after adjusting for other covariates. The significant depressive symptoms by alcohol use interaction indicated that adults with low to average depressive symptoms evidenced a similar likelihood of SAH to those with high depressive symptoms when they also had elevated alcohol use scores. Limitations: We used cross-sectional self-report data. Conclusion: It may be important to conduct suicide risk assessments for justice-involved people who use alcohol even when depressive symptoms are low.

Criminal risk and mental illness in psychiatric inpatient units: An opportunity to provide psychological services for unmet criminogenic needs.

Although the overrepresentation of people with mental illness in the criminal justice system is known, research is needed to identify the frequency of criminal justice involvement and criminogenic treatment needs in inpatient populations to improve continuity of care and access to appropriate treatments. The purpose of this study is to document the frequency of criminal justice involvement among people receiving inpatient community care, as has been done for persons with mental illness in correctional institutions, and to test the association between criminogenic risk and psychiatric symptomatology. The present study uses two samples (n = 94 and n = 142) of adults from two separate acute psychiatric inpatient hospitals in Texas. Data on psychiatric symptoms, mental health history, criminal risk, and criminal justice history were gathered from file review and self-report. Linear and negative binomial regressions were used to test associations of interest. In both samples, the frequency of prior criminal justice involvement was over 50%. The current results indicate there is a significant, positive association between measures of criminal risk and psychiatric symptoms. These findings highlight the need to address the reciprocal association between mental illness and criminal risk among people receiving inpatient psychiatric treatment with appropriate assessment and treatment.

Interpersonal Risk Factors, Sexual and Gender Minority Status, and Suicidal Ideation: Is BDSM Disclosure Protective?

Suicidal ideation is elevated among individuals who engage in BDSM practices and those with sexual and gender minority (SGM) identities. There is limited research on the intersectionality of these identities and how they relate to suicidal ideation, especially within a theoretical framework of suicide risk, such as the interpersonal theory of suicide. Thus, we tested the indirect relation between BDSM disclosure and suicidal ideation through thwarted belongingness and perceived burdensomeness, as well as the moderating role of SGM identity on these indirect associations. Participants were 125 (Mage = 28.27 years; 64% cisgender men) individuals recruited via online BDSM-related forums who endorsed BDSM involvement and recent suicidal ideation. Results indicated significant moderated mediation, such that BDSM disclosure was indirectly negatively related to suicidal ideation through lower thwarted belongingness, but not perceived burdensomeness, among SGM individuals. This was due to the significant relation between BDSM disclosure and thwarted belongingness. There were no significant moderated mediation or indirect effects related to perceived burdensomeness. We also provide supplemental analyses with positive ideation (i.e., positive thoughts toward life) as the criterion variable. In conclusion, BDSM disclosure appears to be protective against suicidal ideation through thwarted belongingness but only for SGM individuals. This work furthers our understanding of the impact of intersecting marginalized identities on suicide risk and resilience. Implications, limitations, and future directions are further discussed.

Interpersonal Trauma and Suicide Ideation: The Indirect Effects of Depressive Symptoms, Thwarted Belongingness, and Perceived Burden.

Suicide risk is elevated among college-aged students and individuals exposed to cumulative interpersonal trauma. This study used the interpersonal theory of suicide as a framework to test the relation between cumulative interpersonal trauma and suicide ideation through the indirect effects of cumulative interpersonal trauma via depression, thwarted belongingness (TB), and perceived burdensomeness (PB), in serial. Participants were 261 college students who endorsed prior trauma and completed cross-sectional study measures online. An atemporal serial mediation model indicated that cumulative interpersonal trauma significantly and indirectly related to suicide ideation through depressive symptoms, TB, and PB. The relation between cumulative interpersonal trauma and suicide ideation was explained by greater depressive symptoms, TB, and PB, in serial. Therefore, depressive symptoms, TB, and PB may be important modifiable clinical targets for college students with a history of cumulative interpersonal trauma.

A human surrogate neck for traumatic brain injury research.

Properties of the human neck such as range and resistance to motion are considered important determinants of the kinematic response of the head pre, during and post-impact. Mechanical surrogate necks (i.e., anthropomorphic test device necks), have generally been limited to a single anatomical plane of motion and an artificially high resistance to motion. The aim of this study was to present the Loughborough University Surrogate Neck that is representative of the 50th percentile human male neck, developed for motion in and between each of the anatomical planes with inertial and flexural stiffness properties matching those of a passive elastic (i.e., negligible active tension) neck muscle state. The complex intervertebral joints were reduced to three encapsulated ball joints with appropriate locations, orientations and distributed range of motion to precisely position and orientate the head with respect to the torso at the neutral position and end range of motion. A plain bearing sub-assembly was incorporated at the C1-C2 vertebral level to permit 50% of the axial rotation with negligible resistance to motion, as exhibited by humans. Detachable elastomeric elements provided resistance to motion across each ball joint and permit any orientation of the head within the physiological range of motion of the joints. The mass of the surrogate neck (1.62 Kg) was in agreement with the typical human range and similar agreement was found for the principal moments of inertia (Ixx 26.8 kg cm2, Iyy 20.5 kg cm2 and Izz 14.3 kg cm2). Quasi-static bending moment and dynamic torque tests characterised the surrogate neck in flexion/extension, lateral flexion and axial rotation. With respect to commercial surrogate necks, the surrogate neck presented here was in closer agreement to the reported human responses, for equivalent loading conditions. The applications of a surrogate neck that can appropriately constrain the head relative to the torso are far reaching in the areas of brain injury mechanism research, and for the development and assessment of protective equipment to reduce the risk of such injuries.

The moderating role of pessimism in the association between retrospective relational peer victimization, interpersonal risk factors, and suicide ideation.

Peer victimization (PV) is a serious concern for youth and is associated with subsequent suicide ideation in young adulthood. The interpersonal theory of suicide may provide a framework for understanding suicide ideation in this population. Specifically, thwarted belongingness (TB) and perceived burdensomeness (PB) have been significantly associated with suicide ideation among young adults with a history of peer victimization. Additionally, the personality trait of pessimism is associated with elevated suicide ideation. Thus, this study tested the association between self-reported frequency of retrospective relational (i.e., verbal and indirect) PV in primary and secondary school, thwarted interpersonal needs (TB and PB), and current suicide ideation, as well as how these relations may vary based on current pessimism. Participants were 330 undergraduate students. Nonparametric bootstrap moderated mediation procedures were used to test hypotheses. Results indicated significant indirect effects of frequency of retrospective relational PV and suicide ideation through PB and TB. Contrary to predictions, results did not indicate significant moderated mediation; however, the association between PB and suicide ideation was stronger at lower pessimism levels. We also provide supplemental analysis with optimism as the moderator. These findings suggest that clinicians may consider targeting TB, PB, as well as pessimism and optimism among those with a history of relational PV when assessing and intervening on current suicide ideation. Implications, limitations, and future directions are further discussed.

Considering the impact of COVID-19 on suicide risk among individuals in prison and during reentry.

PURPOSE -: This paper mains to bring attention to the potential impact COVID-19 could have on suicide risk among individuals who are incarcerated and those reentering the community after incarceration (i.e. reentry), with particular emphasis on the USA, as well as provide possible solutions to mitigate suicide risk. DESIGN/METHODOLOGY/APPROACH -: This paper provides an overview of the association between the COVID-19 pandemic policies and suicide, the vulnerabilities specific to prisoners during the COVID-19 pandemic, relevant suicide risk factors among prisoners, the possible impact of COVID-19 on suicide risk during reentry and proposed solutions for moving forward to mitigate both risks for COVID-19 and suicide. FINDINGS -: This paper highlights that prisoners and individuals reentering the community are particularly vulnerable to COVID-19 and suicide risk and COVID-19-related stressors may further exacerbate known suicide risk factors (e.g. psychiatric symptoms, lack of positive social ties, low feelings of belonging, feelings of burden, economic problems) and suicidal thoughts and behaviors. This paper also discusses barriers (e.g. lack of funds, access to health and mental health care, COVID-19 testing and personal protective equipment) to managing COVID-19 and suicide risk within prisons and during reentry. ORIGINALITY/VALUE -: This paper provides a review of scalable solutions that could mitigate the impact of COVID-19 and suicide risk during this pandemic among prisoners and those reentering the community, such as psychoeducation, self-help stress management, telehealth services, increased access and reduced cost of phone calls, reduced or eliminated cost of soap and sanitization supplies in prisons and early release programs.

Comparative effectiveness of treatment options for displaced midshaft clavicle fractures : a systematic review and network meta-analysis.

AIMS: The aims of this network meta-analysis (NMA) were to examine nonunion rates and functional outcomes following various operative and nonoperative treatments for displaced mid-shaft clavicle fractures. METHODS: Initial search strategy incorporated MEDLINE, PubMed, Embase, and the Cochrane Library for relevant randomized controlled trials (RCTs). Four treatment arms were created: nonoperative (NO); intramedullary nailing (IMN); reconstruction plating (RP); and compression/pre-contoured plating (CP). A Bayesian NMA was conducted to compare all treatment options for outcomes of nonunion, malunion, and function using the Disabilities of the Arm Shoulder and Hand (DASH) and Constant-Murley Shoulder Outcome scores. RESULTS: In all, 19 RCTs consisting of 1,783 clavicle fractures were included in the NMA. All surgical options demonstrated a significantly lower odds ratio (OR) of nonunion in comparison to nonoperative management: CP versus NO (OR 0.08; 95% confidence interval (CI) 0.04 to 0.17); IMN versus NO (OR 0.07; 95% CI 0.02 to 0.19); RP versus NO (OR 0.07; 95% CI: 0.01 to 0.24). Compression plating was the only treatment to demonstrate significantly lower DASH scores relative to NO at six weeks (mean difference -10.97; 95% CI -20.69 to 1.47). CONCLUSION: Surgical fixation demonstrated a lower risk of nonunion compared to nonoperative management. Compression plating resulted in significantly less disability early after surgery compared to nonoperative management. These results demonstrate possible early improved functional outcomes with compression plating compared to nonoperative treatment. Surgical fixation of mid-shaft clavicle fractures with compression plating may result in quicker return to activity by rendering patients less disabled early after surgery.

BRIEF MOTIVATIONAL INTERVENTION FOR SUBSTANCE USE MAY DECREASE VIOLENCE AMONG HEAVY ALCOHOL USERS IN A JAIL DIVERSION PROGRAM.

Rates of harmful alcohol use are high among justice-involved individuals and may contribute to violent recidivism. Robust treatments for alcohol-related violence in criminal justice systems are thus a public health priority. In this analysis of existing randomized controlled trial data (N = 105), we examined the impact of a brief motivational intervention (BMI) for harmful substance use on violent recidivism among individuals in a pretrial jail diversion program. Results indicated that, after controlling for violence history, the intervention's impact on violent recidivism was moderated by baseline harmful alcohol use. Specifically, among people with severe alcohol problems at baseline, the BMI + standard care group had less violent recidivism at a 1-year follow-up than participants randomized to standard care alone. This finding was unchanged when we accounted for psychopathic traits. Our study provides preliminary evidence that a BMI may be useful for decreasing violent recidivism among heavy drinkers in criminal justice systems.
