Higher use of an avoidant and dependent DM styles was associated with a greater likelihood of being in the slow DM speed class. Younger age and psychache was associated with a greater likelihood of being in the high risk DM class.

Evidence on this relationship, however, has been mixed. This study explored the association between FLFP and suicide in an understudied context, Taiwan, and across 40-years.Methods: Annual national labor-participation rates for women ages 25-64, and female and male suicide-rates, for 1980-2020, were obtained from Taiwan's Department of Statistics. The associations between FLFP rates and sex/age-stratified suicide-rates, and between FLFP rates and male-to-female suicide-rates ratios were assessed via time-series regression-analyses, accounting for autoregressive effects.Results: Higher FLFP rates were associated with lower female suicide-rates (ß = -0.06, 95% CI (Credibility Interval) = [-0.19, -0.01]) in the adjusted model. This association held in the age-stratified analyses. Associations for FLFP and lower male suicide-rates were observed in the ≥45 age-groups. FLFP rates were significantly and positively associated with widening male-to-female suicide-rates ratios in the adjusted model (ß = 0.24, 95% CI = [0.03, 0.59]).Conclusion: This study's findings suggest that FLFP protects women from suicide, and point to the potential value of FLFP as a way of preventing suicide. In Taiwan, employed women carry a double-load of paid and family unpaid care-work. Child care-work is still done by mothers, often with grandmothers' support. Therefore, this study's findings contribute to evidence that doing both paid work and unpaid family care-work has more benefits than costs, including in terms of suicide-protection. Men's disengagement from family care-work may contribute to their high suicide rates, despite their substantial labor-force participation.","PeriodicalId":8325,"journal":{"name":"Archives of Suicide Research","volume":" ","pages":"144-162"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140847395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five classes emerged: Extreme (7%, n = 113), featuring pervasive stigma, polysubstance use, high-risk sex, and food and housing insecurity; Severe/marijuana (15%, n = 236), featuring pervasive stigma, alcohol use, marijuana use, high-risk sex, and food insecurity; Severe (18%, n = 296), featuring the same PPEs minus marijuana use; Moderate (17%, n = 267), featuring family stigma, verbal harassment, some polysubstance use, and high-risk sex; and Mild (44%, n = 705), featuring family and friends stigma, verbal harassment, and alcohol use. Significantly higher suicide attempt prevalence emerged in the Extreme/Severe classes (12-16%) relative to the Mild/Moderate classes (2%).Conclusions: Stigma and substance use were common across classes, implicating both as key factors shaping suicide risk among SMM.

Social media provide platforms that allow health communicators to reach a large population. This research focuses on examining and testing the most effective message framing (how the message provides a reward or consequence for the receiver) and message construct (precise focus and wording of a message) for social media posts intended to positively influence suicide gatekeeper intervention behavior on behalf of a friend or peer.Method: An experiment tested the influence of message construct (between subjects) and message frame (within subjects). The experiment randomized the 1285 participants between the ages of 18 and 34 into the three message construct conditions (significance, preventability, and beneficence).Results: The results suggest gain-framed messages have a more positive influence than loss-framed messages on all social media message outcome variables (likelihood of social media message engagement, perceived message effectiveness, self-efficacy, response efficacy, empathy, and behavioral expectation), and state empathy mediates the relationship between message frame and these variables. Message construct condition and other mediation results were less substantial, although some evidence suggests that the significance message construct may increase social media message sharing and perceived message effectiveness.Conclusion: Results show strong evidence of the effectiveness of using gain frames in social media messages aimed at suicide gatekeepers.

We studied suicides reported across three districts of Gilgit-Baltistan (GB); causes, patterns of suicidal behaviors, and classification processes.Methods: A retrospective survey of police records from GB between 2012 and March 2022 was completed using a structured questionnaire that included demographic characteristics, possible causes, and forensic details. Descriptive statistics and a chi-square test of association were applied. This study was approved by the Institutional Review Board of Shifa International Hospital, Islamabad (IRB 0210-22).Results: In total, 340 cases of suicides were registered. Among them, 53% (n = 179) were females, 59% (n = 202) unmarried and 40% (n = 136) below 20 years of age. Stress and mental illnesses were reported in 73% (n = 247) cases. Common methods of suicide were hanging (41%; n = 141) and firearms (25%; n = 85). More men compared to women attempted suicide by firearms while more women died by drowning or poisoning. Greater proportion of individuals who were unmarried and had formal education died by suicide compared to their demographic counterparts. Number of individuals having a \"mental illness\" was higher in men while significantly more women were affected by \"domestic stressors.\" Seven (2.9%) cases reported between 2021 and 2022 were reclassified as homicides.Conclusion: Suicide is more common among females compared to males, unmarried compared to married, and younger population compared to older population.

Modeling SITBs using traditional statistical models has proven challenging. More complex machine learning approaches may offer better performance and insights. We explored and compared multiple machine learning models of suicide ideation, suicide attempts, and non-suicidal self-injury-both past-year frequency and dichotomous lifetime occurrence-among adolescents of diverse gender identities and sexual orientations.Method: Data came from a large adolescent survey (N = 2,452) including psychological and demographic features. We compared prediction performance between generalized linear models, random forest models, and gradient boosting decision tree models using the full sample.Results: Contrary to hypotheses, we found that these models generally performed comparably. We then selected the best-performing model families to run follow-up comparisons between cisgender and gender minority adolescents and between heterosexual and sexual minority adolescents. Depression was consistently the top-ranked feature across all models save one, in which discrimination was the top-ranked feature for lifetime occurrence of suicide attempt in the gender minority group. In addition, loneliness was more important in the gender minority group relative to the cisgender group for models of suicidal ideation.Conclusion: Discrimination and loneliness emerged as important features in predicting SITBs amongst gender minorities. Future work should examine these factors both as possible statistical predictors of SITB risk and as treatment targets for gender minority youth.","PeriodicalId":8325,"journal":{"name":"Archives of Suicide Research","volume":" ","pages":"1-14"},"PeriodicalIF":2.5,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142799174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
