Terapia de Aceptación y Compromiso en conducta suicida: una revisión sistemática / Acceptance and Commitment Therapy on suicidal behavior: a systematic review

El suicidio se ha convertido en un problema social y de salud pública a nivel mundial. En este sentido, la Terapia de Aceptación y Compromiso (ACT) podría ser eficaz en su abordaje, existiendo evidencia sobre la relación entre algunos de sus componentes y la conducta suicida. Así, el presente estudio tuvo por objetivo realizar una revisión sistemática sobre la eficacia de ACT en conducta suicida. Para ello se siguió el protocolo PRISMA, empleando las siguientes bases de datos: PsycInfo, PubMed, Scopus y PsicoDoc. Inicialmente se obtuvieron 108 publicaciones potencialmente relevantes, de las cuales, finalmente, 13 fueron incluidas en la revisión. La calidad de los estudios se analizó a través de un instrumento de evaluación de riesgo de sesgos. Como resultados, a nivel general se observaron disminuciones estadísticamente significativas en ideación suicida (IS) y factores de riesgo de suicidio. Además, algunos estudios señalaron relaciones estadísticamente significativas entre un aumento de flexibilidad psicológica y la disminución de IS. Si bien los datos apuntaron a una posible eficacia de ACT en la reducción de IS, es necesario llevar a cabo mayor número de estudios experimentales que contemplen la complejidad de la conducta suicida y exploren los procesos de cambio implicados.(AU)

Suicide has emerged as a pressing global issue affecting both so-ciety and public health.In this context, Acceptance and Commitment Therapy (ACT) could prove effective in its approach, supported by evi-dence of the relationship between certain components of ACT and suicidal behavior. Thus, the present study aims to conduct a systematic review on the efficacy of ACT in suicidal behavior. For this, the PRISMA protocol was followed, using thefollowing databases: PsycInfo, PubMed, Scopus and PsicoDoc.

Feasibility and Acceptability Study of a Culturally Adapted Web-Based Intervention to Reduce Suicidal Ideation for Syrian Asylum Seekers and Refugees in the United Kingdom: Protocol for a Mixed Methods Study.

BACKGROUND: The war in Syria has displaced over 6.8 million people, more than any other conflict since the Second World War. As a result, Syrian asylum seekers and refugees have experienced several life-changing events, resulting in high rates of anxiety, depression, posttraumatic stress disorder, and suicidal ideation (SI). To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI developed for general populations was culturally adapted for and with Syrian asylum seekers and refugees in the United Kingdom. The study revealed the importance of understanding their lived experience with migration and the acculturative process in providing treatment for SI. This study will now assess the feasibility and acceptability of the culturally adapted intervention for this population. OBJECTIVE: The first phase of the study will include recruiting participants and delivering the web-based intervention (1) to assess the feasibility of meeting recruitment goals and recruitment rates and (2) to assess the feasibility of outcome measures. The second phase of the study will include one-to-one semistructured interviews (1) to assess the suitability of the culturally adapted intervention in terms of recruitment and adherence rates and barriers and facilitators to engagement and (2) to assess the acceptability of the intervention in terms of its cultural relevance and appropriateness. METHODS: This is a protocol for a single-group, noncontrolled, mixed methods feasibility and acceptability study of a culturally adapted web-based intervention to reduce SI for Syrian asylum seekers and refugees in the United Kingdom. The study will assess the feasibility of recruitment goals, recruitment rates, adherence rates, and outcome measures using individual participant tracking forms, which will be analyzed quantitatively. The suitability and acceptability of the intervention will be assessed using one-to-one semistructured interviews with 12 participants who completed the intervention, which will be analyzed qualitatively. RESULTS: Recruitment began in February 2024 and will run until 30 participants are recruited to the study or until the end of July 2024. Thus far, 19 participants have provided informed consent, 16 were eligible and enrolled, and 12 have completed a postintervention interview. No data have been analyzed. The study, including the write-up period, is expected to end in December 2024. CONCLUSIONS: Despite experiencing several stressors related to forced displacement and high rates of mental health issues, access to treatment is still limited for Syrian asylum seekers and refugees in the United Kingdom. To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI was culturally adapted in collaboration with Syrian asylum seekers and refugees in the United Kingdom. This study will now assess the feasibility and acceptability of the intervention and culturally appropriate recruitment strategies.

The Effects of Selective Serotonin Reuptake Inhibitors on Impulsivity in Young Adults with Major Depression in the Early Phase of Treatment. / Majör Depresyonu Olan Genç Eriskinlerde Selektif Serotonin Geri Alim Inhibitörlerinin Tedavinin Erken Döneminde Dürtüsellik Üzerine Etkisi.

OBJECTIVE: Whether selective serotonin reuptake inhibitors (SSRI) increase suicide risk, especially in young adults, is still a controversial issue. This study aimed to examine the change in impulsivity characteristics and to evaluate the relationship between impulsivity and suicidality in young adults with major depression who were started on SSRIs. METHOD: The study included 50 patients between the ages of 18-24 years with a diagnosis of major depression who were planned to start SSRIs. Participants were evaluated with the Beck Depression Scale, Beck Anxiety Scale, Young Mania Rating Scale, Columbia Suicide Severity Rating Scale, Barratt Impulsivity Scale, Daily Impulsivity Scale (DIS), and Go/ No-Go Task (GNG) before and at the end of the first week of treatment. RESULTS: Seventy percent of the patients (n: 35) completed the assessments at baseline and at the end of the first week. At the end of one-week there was a statistically significant decrease in the DIS (t=2.283, p=0.029) and commission errors in GNG (t=3.19, p=0.003). In addition, 7 out of 11 patients who had suicidal ideation at the first evaluation did not continue to have suicidal ideation at the end of the first week and there was a significant decrease in the severity of suicidal ideation at the end of the follow-up (W:132.0, p<0.001). CONCLUSION: One-week SSRI use in young adults resulted in a decrease in impulsivity in self-report scales assessing state impulsivity and in the GNG. It was observed that the severity of suicidal ideation decreased at the end of the one-week treatment period.

Social disconnection correlates of a "Wish to Die" among a large community-dwelling cohort of older adults.

Introduction: Social disconnection and deaths by suicide among older adults are both important public health concerns, particularly in the context of ageing populations. The association between death ideation and behaviours, and social disconnection is well established and both functional and structural social relationships have been identified as predictive of suicide-related thoughts and behaviours. The "Wish to Die" (WTD) involves thoughts of or wishes for one's own death or that one would be better off dead is a commonly used indicator to capture death ideation. It has been shown to be as predictive as active ideation of future suicide attempt. Methods: Data were from a large cohort of community-dwelling older adults aged 50+, The Irish Longitudinal Study on Ageing (TILDA). Cross-sectional analyses of the association between numerous markers of social disconnection (loneliness, social isolation, living alone, marital status, social participation, volunteering, and attending religious service) and WTD were conducted. Results: Multiple markers of social disconnection were associated with a "wish to die". However, loneliness was the strongest risk factor while attendance of religious services was an important protective behaviour. Discussion: There is a strong association between social disconnection and a WTD among older adults. There is also a strong association between depression and a WTD, while attending religious services or similarly prosocial settings may protect older adults from experiencing negative thoughts about dying.

Suicide warning signs of self-identification in patients with mood disorders: a qualitative analysis based on safety planning.

Introduction: Warning signs serve as proximal indicators of suicide risk, making early recognition imperative for effective prevention strategies. This study aimed to explore self-identified suicide warning signs among Chinese patients with mood disorders based on safety planning framework. Methods: Researchers collaborated with patients to develop a safety plan and compiled warning signs based on it. Word frequency and network analysis were conducted to identify key warning signs. Directed content analysis categorized these signs into cognitive, emotional, behavioral, or physiological themes according to the suicide mode theory. Additionally, we examined potential variations in reported warning signs among participants with different demographic characteristics, including age, gender, and history of suicide attempts. Results: "Low mood" and "crying" emerged as prominent warning signs, with "social withdrawal" closely following. Patients commonly reported emotional themes during suicidal crises, often experiencing two to three themes simultaneously, primarily focusing on emotional, behavioral, and physiological themes. Males exhibited a higher proportion of concurrently reporting three sign themes compared to females (P < 0.05), while no difference was observed in warning signs among patients with other demographic traits. Discussion: This study offers a nuanced understanding of warning signs among mood disorder patients in China. The findings underscore the necessity for comprehensive suicide risk management strategies, emphasizing interventions targeting emotional regulation and social support. These insights provide valuable information for enhancing suicide prevention and intervention efforts.

Prevalence of mental disorders among young people living with HIV: a systematic review and meta-analysis.

Objective: This meta-analysis aims to evaluate the global prevalence of mental disorders among young people living with HIV. Methods: A comprehensive search was conducted of the PubMed, Embase, and Cochrane Library databases for articles relevant to the study, published between January 2013 and June 2023. To identify sources of heterogeneity and compare prevalence estimates among various groups, subgroup analyses were conducted. Study heterogeneity was assessed using Cochran's Q and the I 2 tests. The robustness of the findings was ascertained through sensitivity analyses, while publication bias was evaluated with funnel plots and Egger's test. Results: Sixty studies were included in this meta-analysis. It revealed that approximately one-quarter of YLWH experience depression, with a prevalence of 24.6% (95% CI: 21.1-28.2%). The prevalence of anxiety was found to be 17.0% (95% CI: 11.4-22.6%). Regarding suicidality, the prevalence of suicidal ideation and lifetime suicidal ideation in YLWH was 16.8% (95% CI: 11.3-22.4%) and 29.7% (95% CI: 23.7-35.7%), respectively. Additionally, the prevalence rates for suicidal attempts and lifetime suicidal attempts were 9.7% (95% CI: 4.0-15.4%) and 12.9% (95% CI: 2.8-23.1%), respectively. The prevalence of Post-Traumatic Stress Disorder and Attention Deficit Hyperactivity Disorder was identified as 10.5% (95% CI: 5.8-15.2%) and 5.0% (95% CI: 3.1-7.0%), respectively. Conclusion: The findings indicate a heightened risk of mental disorders among YLWH, underscoring the necessity for targeted intervention strategies to mitigate their suffering and potentially diminish the adverse impacts.

Breaking Down Barriers to a Suicide Prevention Helpline: Web-Based Randomized Controlled Trial.

Background: Every month, around 3800 people complete an anonymous self-test for suicidal thoughts on the website of the Dutch suicide prevention helpline. Although 70% score high on the severity of suicidal thoughts, <10% navigate to the web page about contacting the helpline. Objective: This study aimed to test the effectiveness of a brief barrier reduction intervention (BRI) in motivating people with severe suicidal thoughts to contact the suicide prevention helpline, specifically in high-risk groups such as men and middle-aged people. Methods: We conducted a fully automated, web-based, randomized controlled trial. Respondents with severe suicidal thoughts and little motivation to contact the helpline were randomly allocated either to a brief BRI, in which they received a short, tailored message based on their self-reported barrier to the helpline (n=610), or a general advisory text (care as usual as the control group: n=612). Effectiveness was evaluated using both behavioral and attitudinal measurements. The primary outcome measure was the use of a direct link to contact the helpline after completing the intervention or control condition. Secondary outcomes were the self-reported likelihood of contacting the helpline and satisfaction with the received self-test. Results: In total, 2124 website visitors completed the Suicidal Ideation Attributes Scale and the demographic questions in the entry screening questionnaire. Among them, 1222 were randomized into the intervention or control group. Eventually, 772 respondents completed the randomized controlled trial (intervention group: n=369; control group: n=403). The most selected barrier in both groups was "I don't think that my problems are serious enough." At the end of the trial, 33.1% (n=122) of the respondents in the intervention group used the direct link to the helpline. This was not significantly different from the respondents in the control group (144/403, 35.7%; odds ratio 0.87, 95% CI 0.64-1.18, P=.38). However, the respondents who received the BRI did score higher on their self-reported likelihood of contacting the helpline at a later point in time (B=0.22, 95% CI 0.12-0.32, P≤.001) and on satisfaction with the self-test (B=0.27, 95% CI 0.01-0.53, P=.04). For male and middle-aged respondents specifically, the results were comparable to that of the whole group. Conclusions: This trial was the first time the helpline was able to connect with high-risk website visitors who were hesitant to contact the helpline. Although the BRI could not ensure that those respondents immediately used the direct link to the helpline at the end of the trial, it is encouraging that respondents indicated that they were more likely to contact the helpline at a later point in time. In addition, this low-cost intervention provided greater insight into the perceived barriers to service. Follow-up research should be focused on identifying the added value of other components (eg, video or photo material) in the BRI and increasing its effectiveness, especially for men and middle-aged people.

Which Psychosocial Strengths Could Combat the Adolescent Suicide Spectrum? Dissecting the Covitality Model.

Objective: Covitality is a meta-construct of positive intra/interpersonal self-schemas that organize and process life experiences. Its synergy favors psychosocial adjustment and prevents mental health problems during adolescence. At these ages, suicide is one of the leading causes of death worldwide. The purpose of this study was to determine which psychosocial strengths of the covitality model could combat adolescent suicide spectrum. Method: Participants were 5,528 Spanish adolescents aged 12-18 years, 50.74% females. The assessment protocol was completed in schools, under the supervision of the research staff. Statistical analyses were conducted using hurdle models, i.e., modeling zero-inflated count data. This process provided two sets of outcomes: the association - in probabilistic terms - between psychosocial strengths and the absence of suicide indicators (i.e., non-occurrence) and the association of these assets - via regression coefficients - with increased experimentation (i.e., duration/quantity). Results: All psychosocial strengths of the covitality model were related to the non-ocurrence of suicidal thoughts and behaviors, but not all to a shorter duration/quantity of their phenotypic manifestations. Covitality obtained greater association values on suicidal tendencies than its components analyzed independently. Belief in self and engaged living were the second-order factors with the higher estimating capacity. Specifically, emotional self-awareness, enthusiasm, gratitude, family support, and behavioral self-control were key first-order assets. Conclusions: These findings suggest that training adolescents in covitality assets could be an effective strategy for universal prevention against premature suicide. Moreover, this study provide evidence on which psychosocial strengths could counteract each phenotypic manifestation of suicide in order to customize selective and indicated preventive actions.

Psychological Factors Protecting Against Suicidality in Older Adults: A Systematic Review.

OBJECTIVE: Suicide rates in older adults are often the highest of any age group, particularly among high income countries. However, there is a limited understanding of the factors that could protect against suicidality in older age. This systematic review aimed to identify and evaluate the psychological factors that protect against suicidality in older age. METHOD: An a priori protocol was established and registered on PROSPERO (CRD42022343694). EMBASE, MEDLINE, PsycINFO, Web of Science and Scopus were searched. Papers were quality assessed using the Quality Assessment with Diverse Studies (QuADSs) tool. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Seventeen papers were included and narratively synthesised. RESULTS: The initial searches identified 10,673 records, resulting in the screening of 5441 records after the removal of duplicates. The protective factors identified were (1) meaning/purpose in life, (2) reasons for living, (3) coping styles, (4) psychological wellbeing, (5) life satisfaction, (6) personality factors, (7) cognitive functioning, and (8) sense of belonging. The factors with the most empirical support were meaning in life, followed by psychological wellbeing and coping responses, such as primary control strategies, and personality traits, such as positive affect and agency. There was also evidence to suggest that the influence of some protective factors, for example meaning in life, may depend upon stage in older life and gender. CONCLUSION: This review identified several psychological factors that have been found to protect against suicidal ideation in older adults, representing potential treatment targets for reducing suicide in older adults. Recommendations for future research includes greater use of longitudinal and case-control designs, measuring outcomes across the continuum of suicidality and using samples that allow comparison between younger and older adults and within the spectrum of old age.

Epidemiological features of suicidal ideation among the elderly in China based meta-analysis.

BACKGROUND: Studies on the prevalence of suicidal ideation (SI) and its associated factors among the elderly in China show considerable variability. This meta-analysis aims to clarify the epidemiological features of SI in this population. METHODS: We systematically searched English and Chinese databases for relevant literature up to September 15, 2022. The extracted data facilitated the calculation of prevalence and odds ratios (ORs) for factors associated with SI among China's elderly. RESULTS: We analyzed 31 cross-sectional studies, comprising a total of 79,861 participants from over 20 provinces and municipalities. The pooled prevalence of SI was found to be 11.47% [95% confidence interval (CI): 7.82-15.71%]. Significant variations in prevalence were influenced by residence, physical health (including chronic diseases and daily living capabilities), mental health (depressive symptoms and life satisfaction), economic status, and time-specific assessment tools. Notably, the prevalence from 2011-2020 (15.59%, 95% CI: 9.08-23.44%) was almost double that of 2001-2010 (7.85%, 95% CI: 5.08-11.16%). The SI prevalence in the eastern region (8.06%, 95% CI 5.59-10.94%) was significantly lower than in the central and western regions (16.97%, 95% CI 12.04-22.53%). Fourteen factors exhibited a significant pooled OR greater than 1 (p < 0.05), and two factors had ORs less than 1 (p < 0.05), indicating notable association with SI among the elderly. CONCLUSION: SI among China's elderly showed relatively high prevalence and considerable heterogeneity across different characteristics and associated factors. This underscores the need for targeted intervention strategies and standardized temporal assessments of SI to effectively address suicide risk in this population.

Identifying Suicide-Related Predictors Using Overseas Airborne Infantry Brigade Serious Incident Reports.

INTRODUCTION: Suicidal ideation and attempts are considered to be graduated risks for suicide, yet they remain under studied. Suicide is among the leading causes of death in the U.S. for all individuals between the ages of 10 and 64 years. Suicide is a critical problem in the U.S. Military. The U.S. Army suicide rates surpassed civilian rates in 2008 and continue to climb steadily; with U.S. Army soldiers at more than twice the risk than U.S. civilians, and enlisted personnel at more than twice the risk of officers. Suicidal ideation and attempts are routinely reported within U.S. Army brigades using suicide-related serious incident reports (SR-SIRs). These reports could form a useful source of information for prevention planning, but to date there have been no efforts to summary these reports. This paper analyzes SR-SIRs among enlisted personnel for a 4-year period for 1 Army brigade, to test the usefulness of this information and to explore whether risk factors for attempts compared to ideation can be identified. MATERIALS AND METHODS: This report analyzes 130 de-identified reports of suicidal ideation (n = 102) and suicide attempts (n = 28) reported as SR-SIRs from August 2018 to June 2022 among enlisted personnel in an airborne infantry brigade combat team (BCT) outside the continental U.S. Analysis of de-identified data was not considered research by brigade and university human subject/IRB authorities. Fourteen soldier characteristics and context factors were examined to determine if they differentiate the two types of incidents, suicidal ideations and suicide attempts. RESULTS: Unit location and alcohol use at the time of the incident were strongly associated with suicide attempts compared to ideation. Attempts occurred disproportionately during off duty hours, and attempters were more likely to have had prior contact with behavioral health services than ideators; however, these differences did not attain conventional statistical significance. CONCLUSIONS: The study can help inform unit-specific suicide prevention and intervention strategies. Off duty hours and alcohol use are risk factors for attempts, particularly among soldiers who have sought behavioral health care. Plans to engage and support soldiers who have sought behavioral health care during off duty hours, and information regarding the risks of alcohol use, could meaningfully reduce their risk. This is the first known attempt to examine active duty U.S. Army brigade combat team SR-SIRs, and they are a potentially valuable source of health and mental health-related information.

Pre-COVID-19 short sleep duration and eveningness chronotype are associated with incident suicidal ideation during COVID-19 pandemic in medical students: a retrospective cohort study.

Introduction: Cross-sectional evidence suggests that sleep problems increased the risk of suicide during the 2019 coronavirus disease (COVID-19) pandemic. However, a lack of longitudinal studies examined the relationship between pre-COVID-19 sleep duration, chronotype and incident suicide during the COVID-19 pandemic. Thus, we examined these associations in a longitudinal study of medical students. Methods: From the Shantou College Student Sleep Cohort, a total of 333 first and second grade medical students (age 19.41 ± 0.82 years, female 61.26%), without suicidal ideation (SI) at pre-COVID-19 period, were followed up during the COVID-19 pandemic. Incident SI was defined by their response to the 9th question from the Beck Depression Inventory. Short sleep duration was defined as less than 7 h/night. The Morningness-Eveningness Questionnaire was used to evaluate the participants' chronotype. Logistic regression with adjusted odds ratios (AOR) and 95% confidence intervals (95% CI) was used to examine the association between sleep and SI. Results: The incidence of SI during the COVID-19 pandemic was 5.71%. Logistic regressions with confounding factors adjustment showed that both short sleep duration (AOR = 4.91, 95% CI = 1.16-20.74) and eveningness (AOR = 3.80, 95% CI = 1.08-13.30) in the pre-COVID-19 period were associated with increased risk of incident SI during the COVID-19 pandemic. Conclusion: Pre-COVID-19 short sleep duration and eveningness predict incident SI during the COVID-19 pandemic in medical students. Prolonging sleep duration may help to decrease SI during major public health crises.

COVID-19 Pandemic School Disruptions and Acute Mental Health in Children and Adolescents.

Importance: There are suggestions that school pressure may be stressful and a factor in child and adolescent mental health disturbances, but data about this association are scarce and inconclusive. Objective: To assess whether varying degrees of school interruption were associated with changes in emergency department (ED) psychiatric visits of children and adolescents before and after the COVID-19 outbreak. Design, Setting, and Participants: A cross-sectional observational study was conducted at 9 urban university hospitals in Italy. All ED visits from January 1, 2018, to December 31, 2021, for psychiatric reasons of patients younger than 18 years were examined for demographic characteristics and type of psychopathologic factors. Data analysis was conducted from July 1 to August 31, 2023. Exposure: The disruption in the usual succession of school and holiday periods brought on by the COVID-19 pandemic at different times and with various degrees of intensity. Main Outcomes and Measures: Total number of pediatric ED visits, psychiatric ED visits, and psychiatric ED visits categorized by specific reasons (eg, psychomotor agitation, suicide ideation [SI] or suicide attempt [SA], and eating disorders) on a weekly basis. Results: A total of 13 014 psychiatric ED visits (1.3% of all pediatric ED visits) were recorded (63.2% females; mean [SD] age, 13.8 [3.8] years). The number of ED psychiatric visits increased over time (incidence rate ratio [IRR], 1.19; 95% CI, 1.16-1.22 for each year). Significant increases in ED visits were observed for eating disorders (294.8%), SI (297.8%), and SA (249.1%). School opening, but not social lockdown restriction, was associated with an increase in the number of ED psychiatric visits (IRR, 1.29; 95% CI, 1.23-1.34), which was evident for females and for SI with SA. Socioeconomic status was associated with an increase in psychiatric visits for males (IRR, 1.12; 95% CI, 1.04-1.20) but not females (IRR, 1.04; 95% CI, 0.98-1.10). Conclusions and Relevance: In this study, school opening was associated with an increased incidence of acute psychiatric emergencies among children and adolescents, suggesting that school can be a substantial source of stress with acute mental health implications.

An In-Depth Exploration of the Relationship Between Suicidal Ideation and Emotion Processes in Adolescents.

Previous research has shown a relationship between proximal (i.e., close-in-time) emotion experiences and suicidal ideation (SI). Yet, it remains unclear which emotion processes (i.e., the level of the emotion [intensity], how much emotions vary [variability], emotional consistency [inertia], how specific emotions are [differentiation]) and which emotions (i.e., sadness, hopelessness, anger, nervousness, happiness) are most potent predictors of SI. Seventy-seven adolescents (67.5% assigned female at birth) completed daily diaries for 4 weeks after psychiatric hospitalization. Levels of the above-mentioned emotions and frequency of SI were recorded. For each week and each emotion, mean (intensity), standard deviation (variability), autocorrelation (inertia), and intraclass correlation coefficients (ICCs; negative emotion differentiation) were calculated (i.e., four observations/person). Multilevel models examined whether (a) mean intensity, variability, and their interaction; and (b) mean intensity, inertia, and their interaction, were related to mean weekly SI frequency. A separate model examined whether negative emotion differentiation was related to mean weekly SI frequency after adjusting for mean intensity. A significant interaction between mean intensity of anger and variability of anger emerged (B = 0.54, SE = 0.24, p = .023); a positive relationship between mean anger and mean SI frequency was present at moderate or high levels of anger variability but not at its low levels. Mean intensity of most emotions was related to SI frequency in the expected directions. No other statistically significant findings emerged. Results revealed the importance of considering multiple emotion features, their dynamic nature, and their combined effect. Future research should explore mechanisms accounting for anger being related to heightened proximal SI, along with an examination of effective intervention strategies to reduce anger intensity and variability.

Identifying Reddit Users at a High Risk of Suicide and Their Linguistic Features During the COVID-19 Pandemic: Growth-Based Trajectory Model.

BACKGROUND: Suicide has emerged as a critical public health concern during the COVID-19 pandemic. With social distancing measures in place, social media has become a significant platform for individuals expressing suicidal thoughts and behaviors. However, existing studies on suicide using social media data often overlook the diversity among users and the temporal dynamics of suicide risk. OBJECTIVE: By examining the variations in post volume trajectories among users on the r/SuicideWatch subreddit during the COVID-19 pandemic, this study aims to investigate the heterogeneous patterns of change in suicide risk to help identify social media users at high risk of suicide. We also characterized their linguistic features before and during the pandemic. METHODS: We collected and analyzed post data every 6 months from March 2019 to August 2022 for users on the r/SuicideWatch subreddit (N=6163). A growth-based trajectory model was then used to investigate the trajectories of post volume to identify patterns of change in suicide risk during the pandemic. Trends in linguistic features within posts were also charted and compared, and linguistic markers were identified across the trajectory groups using regression analysis. RESULTS: We identified 2 distinct trajectories of post volume among r/SuicideWatch subreddit users. A small proportion of users (744/6163, 12.07%) was labeled as having a high risk of suicide, showing a sharp and lasting increase in post volume during the pandemic. By contrast, most users (5419/6163, 87.93%) were categorized as being at low risk of suicide, with a consistently low and mild increase in post volume during the pandemic. In terms of the frequency of most linguistic features, both groups showed increases at the initial stage of the pandemic. Subsequently, the rising trend continued in the high-risk group before declining, while the low-risk group showed an immediate decrease. One year after the pandemic outbreak, the 2 groups exhibited differences in their use of words related to the categories of personal pronouns; affective, social, cognitive, and biological processes; drives; relativity; time orientations; and personal concerns. In particular, the high-risk group was discriminant in using words related to anger (odds ratio [OR] 3.23, P<.001), sadness (OR 3.23, P<.001), health (OR 2.56, P=.005), achievement (OR 1.67, P=.049), motion (OR 4.17, P<.001), future focus (OR 2.86, P<.001), and death (OR 4.35, P<.001) during this stage. CONCLUSIONS: Based on the 2 identified trajectories of post volume during the pandemic, this study divided users on the r/SuicideWatch subreddit into suicide high- and low-risk groups. Our findings indicated heterogeneous patterns of change in suicide risk in response to the pandemic. The high-risk group also demonstrated distinct linguistic features. We recommend conducting real-time surveillance of suicide risk using social media data during future public health crises to provide timely support to individuals at potentially high risk of suicide.

An Umbrella Review of Cognitive Behavioural and Dialectical Behavioural Therapies to Treat Self-Harm and Suicidal Behaviour in Adolescents.

BACKGROUND: The incidence of self-harm and suicidal behaviour in adolescents is increasing. Considering the great impact in this population, an actualization of the evidence of those psychological treatment's excellence for suicidal behaviour. Thus, the aim of this paper is to compile the available evidence on the effectiveness of cognitive behavioural therapy and dialectical behavioural therapy in preventing self-harm and suicidal behaviour in adolescents. METHODS: A umbrella review was carried out, different databases (PubMed, CINAHL, Cochrane Library, Psyinfo, Embase, Web of Science, Scopus and Google Scholar) were consulted. The 16-item measurement tool to assess systematic reviews-2 (AMSTAR-2) were performed by two independent reviewers and any discrepancies were resolved by consensus. The Rayyan-Qatar Computing Research Institute was used for the screening process. RESULTS: Nine systematic reviews were included. Cognitive Behavioural Therapy appears to reduce the incidence of suicide-related events compared with treatment as usual, compared to usual treatment (which usually consists of drugs and talk therapy) especially when combined with fluoxetine. Dialectical behavioural therapy seems to be associated with a reduction in suicidal ideation and self-harm. CONCLUSIONS: Although the results found show results with high heterogeneity. The evidence on cognitive behavioural therapy and dialectical behavioural therapy for suicide prevention, self-harm and suicide ideation in adolescents seems to show positive results. Considering, the special population and great impact, further research is needed and comparable studies should be sought that allow to set up robust recommendations.

Mental Health and Suicidal Behaviour in Chilean Youth during the Covid-19 Pandemic.

BACKGROUND: The pandemic caused by the SARS-CoV-2 virus led to a series of containment and mitigation measures through lockdowns, social distancing, and the closure of educational establishments, which have had a profound impact on the mental health of the adolescent population. OBJECTIVE: The main objective of the present study has been to identify the sociodemographic and mental health variables related to suicidal ideation, planning, and attempts in young people participating in outpatient intervention projects within the Chilean protection network since the onset of the pandemic and the strictest lockdowns. METHOD: The study's sample consists of 125 young people aged 14 to 18 years (M = 15.65; SD = 1.22), participating in outpatient intervention projects within the National Service for Minors (SENAME)/Better Childhood protection network. Through a self-report survey, the young participants provided responses on sociodemographic variables and suicidal behaviour (ideation, planning, and attempts). RESULTS: 29.9% of the participants reported suicidal ideation during the onset of the pandemic and the established lockdowns; 29.2% reported having devised a plan to do so, and 18.2% indicated having attempted suicide during the evaluated period. A higher occurrence of suicidal behaviour was observed in females, sexual minorities, respondents over 15 years old, and respondents presenting depressive symptoms. CONCLUSIONS: The Covid-19 pandemic has had a significant impact on suicidal behaviour among the adolescent population served by the protection network in Chile. The prior violation of their rights may have contributed to the issue, particularly affecting young females in late adolescence with indicators of depression, who require specialized intervention due to the high risk detected.

Childhood maltreatment associated suicidal risk in Chinese children and adolescents: a mediation of resilience.

BACKGROUND: Existing evidence suggests that children and adolescents who had experienced childhood maltreatment (CM) are at higher suicidal risk. However, the mediation role of resilience in this association remains unclear. We aim to investigate the mediation via resilience in the associations between CM and three suicidal risk indicators (suicidal ideation, SI; suicidal plan, SP; suicidal attempt, SA) among a large sample of Chinese children and adolescents. METHODS: A population-based cross-sectional survey was conducted in southwestern China Yunnan province. A total of 9723 children and adolescents were included and analyzed by using a multi-stage stratified cluster sampling design. Univariate and multivariate logistic regression models were fitted to explore the associations between CM, resilience, and the three suicidal risk indicators, dose-response trends further elucidated by using the restricted cubic splines. Path models were adopted to estimate the mediation of resilience. RESULTS: The estimated prevalence rates for one-year SI, SP and SA were 32.86% (95% CI: 31.93-33.80%), 19.36% (95% CI: 18.57-20.16%) and 9.07% (95% CI: 8.51-9.66%). After adjustment, CM significantly associated with all 3 suicidal risk indicators, and the odds ratios (ORs) were 2.13 (95% CI: 1.91-2.37), 2.45 (95% CI: 2.13-2.81), and 3.61 (95% CI: 2.90-4.52) for one-year SI, SP, and SA, respectively. Path models revealed that resilience significantly mediated the associations between CM and the three suicidal risk indicators, and among all dimensions of resilience, family support presented the strongest mediation consistently. CONCLUSIONS: Our study results suggest that intervention measures which focusing on improving psychological resilience might be effective in reducing suicidal risk for children and adolescents who had experienced maltreatment. Prospective studies should be done to corroborate our findings.

Psychotropic Medications Promote Time-Dependent Reduction of Suicidal Ideation in Mood Disorder: A Prospective Cohort Study.

BACKGROUND: Despite a plethora of research on the topic, there is still no solid evidence that pharmacological treatment actually reduces the risk of suicide in patients with mental illness. In this study, we aimed to assess the effect of psychotropic medications on suicidal ideation in patients with major depressive disorder (MDD) and bipolar disorder (BPD) in two age groups: less than 25 years and 25 years and older. METHODS: We analyzed 312 patients with mood disorders with current suicidal thoughts or recent suicide attempts. We followed the participants from baseline for 6 months and assessed changes in suicidal ideation with Columbia-Suicide Severity Rating Scale (C-SSRS). The effect of psychotropic drug administration on suicidal ideation over time was analyzed using a linear mixed model. RESULTS: In patients aged 25 years and older with mood disorders, suicidal ideation was more severe when using psychotropic drugs than when not using them. However, suicidal ideation decreased rapidly over time. The time-dependent reduction in suicidal ideation was accelerated when using antidepressants and sedatives/hypnotics in adult MDD, and when using mood stabilizers in adult BPD. However, this effect was not observed in participants aged less than 25 years. CONCLUSION: Adequate psychotropic medication may reduce suicidal ideation in patients with mood disorders aged 25 years and older. Additional research on psychotropic drugs is needed to effectively reduce the risk of suicide among children and adolescents with mood disorders.
