Analysis of risk factors of suicidal ideation in adolescent patients with depression and construction of prediction model

BACKGROUND Major depressive disorder is a common mental illness among adolescents and is the largest disease burden in this age group.Most adolescent patients with depression have suicidal ideation(SI);however,few studies have focused on the factors related to SI,and effective predictive models are lacking.AIM To construct a risk prediction model for SI in adolescent depression and provide a reference assessment tool for prevention.METHODS The data of 150 adolescent patients with depression at the First People's Hospital of Lianyungang from June 2020 to December 2022 were retrospectively analyzed.Based on whether or not they had SI,they were divided into a SI group(n=91)and a non-SI group(n=59).The general data and laboratory indices of the two groups were compared.Logistic regression was used to analyze the factors influencing SI in adolescent patients with depression,a nomogram prediction model was constructed based on the analysis results,and internal evaluation was performed.Receiver operating characteristic and calibration curves were used to evaluate the model’s efficacy,and the clinical application value was evaluated using decision curve analysis(DCA).RESULTS There were differences in trauma history,triggers,serum ferritin levels(SF),highsensitivity C-reactive protein levels(hs-CRP),and high-density lipoprotein(HDLC)levels between the two groups(P<0.05).Logistic regression analysis showed that trauma history,predisposing factors,SF,hs-CRP,and HDL-C were factors influencing SI in adolescent patients with depression.The area under the curve of the nomogram prediction model was 0.831(95%CI:0.763–0.899),sensitivity was 0.912,and specificity was 0.678.The higher net benefit of the DCA and the average absolute error of the calibration curve were 0.043,indicating that the model had a good fit.CONCLUSION The nomogram prediction model based on trauma history,triggers,ferritin,serum hs-CRP,and HDL-C levels can effectively predict the risk of SI in adolescent patients with depression.

Socio-Psychological Factors of Rising Trend of Suicidal Ideation among Indigenous Workforce: Evidence from Himalayan Range

Apart from socio-economic disparities,indigenous people of the Himalayan range in Asia face an increasing trend of suicides.The tragic suicidal events usually go unaddressed,and no strategies are presently in place to mitigate suicides in the future.This study aims to explain the prevailing causes of suicidal ideation to come up with some policy recommendations.Through a preliminary survey,we identified social stigma,social isolation,lack of healthcare facilities,and domestic violence as the potential reasons for suicidal ideation.We identified individuals with suicide ideation for further data collection to test the relationships between the identified variables and suicidal ideation.A quantitative,explanatory and cross-sectional design was used to test the hypotheses.Inferential statistics were applied to the data containing 314 responses,and the results revealed that all the predictive variables influence the formation of suicidal ideation.The study uncovered some new dimensions of social stigma and social isolation that are common among the indigenous people.The results also indicate that some domestic violence is socially acceptable and considered a normal familial matter.Thefindings have theoretical and practical implications.We have identified new dimensions of social stigma,social isolation,and domestic violence that are new additions to the existing bank of literature.It provides insights to encourage public authorities,healthcare providers,and NGO managers to play their role in the right direction to mitigate the problem.This study opens further venues for researchers to investigate the complex issue of suicide more deeply.

Depression and Suicidal Ideations among Older Persons Living with HIV/AIDS in Mbarara City, Southwest Uganda

Background: Due to the increase in longevity and use of antiretroviral treatment, Uganda has had a growing population of older persons living with HIV/AIDS. However, there is a paucity of information on the mental health of the elderly living with HIV/AIDS. In this cross-sectional study, we determined the prevalence of, and associated factors for depression and suicidal ideation among older persons living with HIV/AIDS in Mbarara city, southwest Uganda. Methods: Older persons (150 females, 115 males), with mean age = 64.2 (±5.1) years, accessing health services from three purposively selected HIV/AIDS care centers in Mbarara city, southwest Uganda were recruited. Data on depression and suicidal ideation were collected using a Patient Health Questionnaire (PHQ-9) validated in Uganda, and a structured questionnaire was used to collect data on clinical and socio-demographic characteristics. Data were analysed using logistic regression. Results: Approximately 8.3% and 12.1% had depression and suicidal ideation, respectively. The factors associated with lowering the likelihood of depression were: an increase in the number of family members they stayed with and having no having any problems with their ARVs. On the other hand, earning more than 100,000 Uganda shillings was associated with reducing the risk of suicidal ideations among the participants. Conclusion: Approximately 8 to 12 in 100 older persons living with HIV/AIDS in Uganda have experienced depression or suicidal ideation. Family support and financial control were instrumental factors associated with depression and suicidal ideations, respectively. We recommended strengthening family structures and creating more avenues for financial independence among older persons living with HIV/AIDS to reduce the burden of depression, and suicidal behaviours among this vulnerable population.

Depression and Suicidal Ideations among Prisoners of the Douala Central Prison

Introduction: The prison environment is a conducive environment for the development of psychiatric pathologies such as depression and suicidal ideation. To date, no related study has been conducted in Douala, Cameroon. We have therefore undertaken to study the prevalence of these pathologies and their related factors among inmates of the Douala Central Prison. Method: We conducted a cross-sectional study of 309 prisoners over a 6-month period from 1 January to 31 June 2022. This involved prisoners aged 18 years and over, who were consenting and able to read and write. Data were collected during individual interviews using a structured questionnaire. Depression was assessed by the BECK Short Form Depression Inventory and suicidal ideation was assessed by the MINI. These data were processed using the SPSS version 25.0 software. The related factors were studied in bivariate and multivariate analysis. Results: Most of the prisoners were male (97%), and more than half knew their criminal status. The prevalence of depression was 33.7% and that of suicide ideation was 22.7%. Among the factors associated with depression were receiving social visits and suicidal ideation. A history of physical/psychological abuse, repeated offences and prison violence were protective factors. Factors associated with suicidal ideation were the absence of social visits, physical abuse in childhood, smoking in prison and depression. Suicidal ideation was independently associated with depression as well as depression being independently associated with suicidal ideation. Conclusion: About 1/3 of the prisoners had depression and almost 1/4 had suicidal ideations. As a result of this and the related factors, there is a need to reorganize psychiatric care within our prison context.

Suicidal Ideation and Attempts during Middle Childhood: Associations with Subjective Quality of Life and Depression

Background: Confronted to the increasing suicide rate in children, clinicians have to better understand and predict suicide-related behaviours (SRBs) in children with and without depressive symptoms. Aims: To investigate associations among suicidal tendencies (thoughts and/or attempts), depression and children’s perceptions of subjective quality of life. Methods: This was a cross-sectional study of 157 children of 6 - 13-year-old. Results: Children who attempted or thought of suicide reported goodless subjective quality of life than nonsuicidal children did, and children who thought of or attempted suicide reported higher levels of depressive symptoms than nonsuicidal children. Limitations: A more rigorous approach to investigating suicidal ideation and depressive symptomatology as a diagnostic interview based on the DSM-IV-TR will be valuable to future progress in understanding children’s suicidality. Conclusions: Results may reflect the confirmation of depressive symptoms as risk factors for suicidality and underline the high importance of social and emotional life context among suicidal children. For this reason, more effective recognition and comprehension of the underlying affective and social conditions of children with suicidality have special importance to prevent future suicidal behaviour during adolescence.

Effects of Stress, Depression, and Problem Drinking on Suicidal Ideation among Korean Workers

The mental health of workers is an important issue that affects not only individuals and their families but also workplaces and communities.Therefore,it is necessary to regularly evaluate and analyze workers’mental health status,including levels of stress,depression,and addictive behaviors to apply thesefindings in creating mental health promotion programs.This study aims to provide basic data that would facilitate early intervention for workers’mental health problems by analyzing factors such as stress,depression,and problem drinking that can affect suicidal ideation.From April 15 to October 25,2019,a survey was conducted with 165 workers across six workplaces in a Korean city.Analysis was performed using descriptive statistics,correlation,and simple and multiple regression analyses using the R statistics program 4.0.3.There was no difference in suicidal ideation scores based on the participants’general characteristics,while there was a significant positive correlation among stress,depression,problem drinking,and suicidal ideation.In addition,severe depression,severe stress,and severe problem drinking had significant effects on suicidal ideation,and among the subitems of stress,somatic symptoms had an effect on suicidal ideation.In addition,severe stress,somatic symptoms,depression,and severe problem drinking had a significant effect on suicidal ideation in males but not in females.It is necessary to identify the effects of stress,depression,drinking problems,and suicide on workers’mental health,and evaluate their mental health systemati-cally and regularly to recognize whether active psychiatric treatment and nursing intervention are necessary as well as preventive management.In addition,it is meaningful to pay attention to the suicide ideation of adult workers and provide basic data to promote systematic public health policies on mental health.

Suicidal Ideation among Depressed People Living with HIV/AIDS in Nigeria, West Africa

Objective: Transient suicide thoughts are common to some people throughout the course of HIV disease and often do not indicate significant risk of suicide. However, persistent suicidal thoughts with associated feelings of hopelessness and intent to die are very serious and must be assessed promptly and carefully. The aim of this study, therefore, was to examine the relationship between depression, hopelessness, psychosocial stressors and suicidal ideation in PLWHAs. Methods: This was a hospital based, cross sectional, descriptive study, of one hundred and seventy depressed adult HIV/AIDS patients of Kwara State Specialist Hospital, Ilorin. Depression and suicidal assessment were evaluated using the PHQ-9 scale. A score of >9 or any affirmative response to question 9 of the PHQ-9 scale necessitated suicidal risk assessment. The social determinant questionnaire was used to evaluate social cohesion and negative life events. Results: The prevalence of depression among the HIV/AID patient was 56.7%. Twenty nine (17.1%) were hopeless, twenty eight (16.5%) had at one time or the other thought of taking their lives, six (3.5%) had plan to take their lives. There was strong statistical association between depression, hopelessness (p-value = 0.000) thought of taking life (p-value = 0.000) and plan to take their lives (p-value = 0.030). Conclusion: The significant correlations between hopelessness, depression and suicidal ideation are important markers that should alert clinicians to underlying suicide risk in HIV-positive patients. In addition, low social cohesion and stressful life events were found to be risk factors for depression and suicide. Clinicians should routinely enquire about suicidality in PLWHAs to assist early diagnosis and intervention.

Self-Efficacy as a Suicidal Ideation Predictor: A Population Cohort Study in Rural Japan

Background: Self-efficacy has been widely studied in suicide, both in its causality and treatment effects. However, the evidence of causality is still ambiguous and there is a lack of generalizability. The aim of this study was to examine the relationship between self-efficacy and suicidal ideation through a population cohort study. Methods: The community-based household survey using a self-administered questionnaire was conducted in a rural area of Japan, Happo Town, in Akita Prefecture with community residents aged 30 and over at two respective time points by local health volunteers. The baseline survey was conducted in 2010 with a response rate of 88.9% (n = 6044). Among them, 3812 residents met the inclusion criteria for the follow-up survey in 2012 where the response rate was 75.3% (n = 2869). Exposure variables to suicidal ideation included demographic details, depression and self-efficacy. The Institutional Review Board and the Ethics Committee of Akita University approved the study protocol and all subjects signed informed consent. Results: A total number of 2105 participants (76.4%) without suicidal ideation in the baseline study were enrolled into the follow-up study, and 8.2% of them had developed suicidal ideation. These participants with suicidal ideation were significantly less likely to be married/cohabitant;they had worse subjective health, poorer self-perceived economic status, stronger depressive mood, and lower self-efficacy scores. The odds ratio of the self-efficacy scores at follow-up survey for participants who had developed suicidal ideation were about 2 times lower than at baseline (95% confidence interval = 1. 53 - 3.06). After adjusting for all confounding factors, the association was still significant (OR = 1.66, 95% CI = 1.15 - 2.42). Conclusion: This result suggests that suicidal ideation may be prevented by increasing self-efficacy. We suggest that self-efficacy can be an effective tool for identifying people with suicidal ideation, and increasing self-efficacy can be strategically beneficial for larger suicide prevention.

Non-Violent Communication and Its Impact on Suicidal Ideations and Coping with Stress Styles

One of the important dimensions of violence is suicide, or violence directed toward self that many people suffer from nowadays. In the meantime, adolescents and especially girls are more likely to be harmed. The purpose of this study was to evaluate the effect of group training with non-violent communication (NVC) method on suicidal ideations and coping with stress styles of adolescent girls. The target community in this research was availably selected from the charity centers of Tehran suburbs. In this study, 15 adolescent girls were in the experimental group and 15 in the control group. The criteria for entering the research were students aged 11 to 19 years and the vulnerable socio-economic income. Eight training sessions of NVC were presented for the experimental group in the pre-test and post-test intervals, while no intervention was performed for the control group. Data collection instruments were Beck’s scale for suicidal ideation (BDI) and Endler & Parker’s coping inventory for stressful situations (CISS). After statistical analysis, the effectiveness of this training was investigated on dependent variables by multivariate analysis of covariance. Eventually, the results showed a significant difference between the experimental and control groups (p < 0.05). The finding of the study showed that NVC training can reduce suicidal ideations in adolescent girls who are socially and economically vulnerable. According to the findings, non-violent communication training has a higher effect on emotion-focused coping style compared to other stress coping styles.

Proposed Scales for Measuring Suicidal Ideation in Adult Cancer Patients

Suicidal ideation, which can occur in oncology patients, is associated with suffering and a reduced quality of life. Empirical studies indicate that the incidence of suicide in people with cancer is approximately twice that of the general population. Objective: This cross-sectional descriptive study was designed to establish the prevalence of suicidal ideation in adult oncology patients based on a combination of scales to measure this variable. Method: A battery of three instruments (Scale for Suicidal Ideation. Item 9 of Beck’s Depression Inventory, and a semi-structured interview) was used to make estimates that are not based on just one test and can thus make a comprehensive evaluation of suicidal ideation in the study sample. Four approximations, based on different items from suicidal ideation assessment scales, were developed to determine the most sensitive combination for identifying the presence of suicidal ideation in adult cancer patients. Results: The highest prevalence of suicidal ideation found with the proposed scales was 24.5% (CI = 16%-33%) with Scale 1;23.6% (CI = 15.2%-32%) with Scale 2;and 19.1% (CI = 11.3%-26.9%) with Scale 4. The lowest prevalence of suicidal ideation was 17.3% (CI = 9.8%-24.8%) with Scale 3. Conclusions: Suicidal behavior in the oncology patient should be assessed;however, there is a need to select sensitive instruments that can be applied easily and are suitable for the target group, which faces difficulties in participating in extensive evaluations.

Childhood maltreatment and suicide ideation: A possible mediation of social support

BACKGROUND Existing literature suggests a positive link between childhood maltreatment(CM)and suicide ideation(SI).Nevertheless,whether social support significantly mediates this association remains unknown.AIM To investigate whether social support significantly mediates the association between CM and SI.METHODS In this cross-sectional study of 4732 adolescents from southwest China,we intended to discuss the association between CM and multiple types of SI.In addition,the mediation of major types of social support in this association was also investigated.A self-administrated questionnaire was used to collect the data.A series of multivariate logistic regression models were employed to estimate the association between different types of CM,social support,and SI.The possible mediation of social support in the association between CM and SI was assessed using the path model.RESULTS Based on the cutoffs for subscales of Childhood Trauma Questionnaire,928(19.61%),1269(26.82%),595(12.57%),2337(49.39%),and 3067(64.81%)respondents reported physical abuse,emotional abuse,sexual abuse,physical neglect,and emotional neglect,respectively.Among all the social sources,parental support presented as a significant mediator in the association between emotional maltreatment,both abuse and neglect,and all three types of SI:1-wk,1-year,and lifetime.Parental social support mediated 5.31%and 29.23%,4.80%and 24.50%,and 7.04%and 44.42%of the overall emotional abuse-SI and emotional neglect-SI associations,respectively.CONCLUSION Our findings suggest that improving parental social support might be effective in preventing suicidal risk related to childhood emotional maltreatment in adolescents.

大学生自杀意念与亲子依恋和同伴依恋及生命意义感的关系

目的:探讨大学生自杀意念与亲子依恋的关系,以及同伴依恋和生命意义感在其中的作用。方法:选取1137名大学生,采用自杀意念量表(PANSI)考察自杀意念、修订版父母同伴依恋量表(IPPA-R)考察亲子依恋和同伴依恋、生命意义量表(MLQ)考察生命意义感。结果:父子依恋、母子依恋、同伴依恋、拥有意义、寻求意义得分与PANSI得分均呈负相关(r=-0.51~-0.19,均P<0.001)。同伴依恋与拥有意义的中介作用及链式中介作用效应值分别是-0.08、-0.16、-0.04,分别占总效应的13.83%、25.83%、6.17%。结论:大学生亲子依恋与自杀意念相关,可以通过提升同伴依恋水平、提高拥有意义感来降低自杀意念。

基于机器学习的自杀意念原因特征分析

自杀是世界上最重大的公共卫生危机之一,它已超过战争、他杀和自然灾害加在一起的死亡总和。本文在具有自杀意念的社交媒体的文本中使用计算机技术、机器学习和深度学习的方法,自动抽取自杀意念原因,并探索内容特征(词、词性、语法)和情感心理特征(语言、情感、自杀心理)对自杀意念原因自动抽取任务的影响。实验结果表明,内容特征作为特征中最主要和最重要的特征表现较好,其中词特征的表现最好,而词性特征和语法特征由于词本身的包含关系,在某种程度上被词特征所覆盖。情感心理特征则对内容特征有较好的完善和补充的效果,情感、情绪或心理的表达对自杀意念原因有较相关的正比例关系。

暴力暴露与青少年自杀意念的关系:一个有调节的中介模型

采用暴力暴露问卷、青少年自杀意念量表、自尊量表对4498名被试进行调查,以探讨暴力暴露对青少年自杀意念的影响及自尊在二者关系中的作用机制和性别的调节作用.结果显示:暴力暴露显著正向预测青少年自杀意念;自尊在暴力暴露与青少年自杀意念之间起部分中介作用;性别调节了自尊中介作用的后半段路径,即相较于女生,男生的自尊水平对自杀意念的负向预测作用更强.由此可知,目睹或亲历暴力暴露会导致青少年自杀意念产生的可能性增加,因此可以通过提升自尊水平来减少暴力暴露对自杀意念的消极影响,这一点在男生群体中作用更加显著.
