One-year incidence, predictors, and accuracy of prediction of suicidal thoughts and behaviors from the first to second year of university.

BACKGROUND: Research is scarce on the prospective predictors of first onset suicidal thoughts and behaviors (STB) and the accuracy of these predictors in university students, particularly in low-and-middle income countries. Therefore, we assessed the 1-year incidence of STB among first-year students, a broad range of prospective predictors of STB incidence, and evaluated the prediction accuracy of a baseline multivariate risk prediction model to identify students at highest risk for STB onset over the subsequent 12 months. METHODS: Students (n = 3238) from 13 universities in Mexico completed an online survey developed for the World Mental Health International College Student Surveys in their first year and again 12 months after. We ran generalized linear models and receiver operator curves. RESULTS: The 1-year incidence of suicidal ideation, plan and attempt was 8.53%, 3.75%, and 1.16%, respectively. Predictors in final models were female sex (ideation only), minority sexual orientation (ideation only), depression, eating disorders, ADHD (ideation and plan), ongoing arguments or breakup with a romantic partner (ideation only), emotional abuse (ideation only), parental death (ideation, plan), not Catholic/Christian (ideation, plan), not having someone to rely on, psychotic experiences (plan only), and insufficient sleep (attempt only). Prediction accuracy for ideation, plan and attempt was area under the curve = 0.76, 0.81 and 0.78, respectively. Targeting the top 10% of students at highest risk could reduce STB in the subsequent year up to 36%. CONCLUSIONS: By assessing these risk/protective factors in incoming students we identified students at greatest risk for developing STB to whom suicide prevention strategies could be targeted.

Comparison of suicide attempts among nationally representative samples of Mexican adolescents 12 months before and after the outbreak of the Covid-19 pandemic.

BACKGROUND: There is serious concern over the increase in mental health problems during the coronavirus disease 2019 (Covid-19) pandemic. METHODS: Based on data from two Mexican National Health and Nutrition Surveys conducted in 2018-2019 and 2020 (n = 17,925 and 4,913, respectively), we estimated the prevalence of suicide attempts among adolescents 10-19 years old in the previous year. We constructed a multivariate logistic regression model adjusted by sociodemographic characteristics and contextual variables for the Covid-19 pandemic. RESULTS: The prevalence of suicide attempts in the previous year was similar in both surveys. We found that women, youth in urban localities and individuals living in households where a family member had lost her/his job as a result of the Covid-19 contingency were more likely to attempt suicide compared to their counterparts. On the other hand, attending classes online proved to be a protective factor (aOR=0.3, 95% CI=0.1, 0.8, p = 0.022). LIMITATIONS: The principal limitation of our study concerned the restricted size of our sample for the 2020 survey wave. CONCLUSIONS: Population-level policies aimed at providing economic protection and helping youth to return to school would exert a favorable impact on the mental health and suicidal behavior of youths.

Psychosocial Correlates of Suicidal Behavior among Adolescents under Confinement Due to the COVID-19 Pandemic in Aguascalientes, Mexico: A Cross-Sectional Population Survey.

Background: Suicide and suicidal behaviors were already a global public health problem, producing preventable injuries and deaths. This issue may worsen due to the COVID-19 pandemic and may differentially affect vulnerable groups in the population, including children, adolescents, and young adults. The current study evaluated the association of affective variables (depression, hopelessness, and anxiety), drug use (alcohol, tobacco, and others), emotional intelligence, and attachment with suicidal behaviors. Methods: A state-wide survey included 8033 students (51% female, 49% male; mean age of 16 years) from science and technology high-schools using a standardized questionnaire that was distributed online. Multinomial logistic regression models tested associations between suicidal behaviors and several covariates. The analyses accommodated the complex structure of the sample. Results: Approximately 21% of all students reported a suicidal behavior (11% with a low-lethality suicide attempt, 6% with self-injuries, and 4% with a high-lethality suicide attempt). Variables associated with higher odds of suicidal behavior included: female sex, depression, hopelessness, anxiety, alcohol and tobacco use, childhood trauma, and having to self-rely as issues affecting attachment, and low self-esteem. Security of attachment was associated with lower odds of suicidal behavior. Conclusions: The complexity of suicidal behavior makes it clear that comprehensive programs need to be implemented.

Comparative Analysis of Lifetime Suicide Attempts among Mexican Adolescents, over the Past 12 Years.

OBJECTIVE: To compare the occurrence of suicide attempts across nationally representative samples of the Mexican adolescent population over the past 12 years, and to analyze its association with sociodemographic, lifestyle and mental-health indicators. METHODOLOGY: Data were drawn from the 2006, 2012 and 2018 National Health and Nutrition Surveys (n = 25,056; 21,509; and 17,925 adolescents, respectively). Estimates were based on standardized measurements. RESULTS: The estimated lifetime prevalence rates of suicide attempts were 1.1% in 2006, 2.7% in 2012, and 3.9% in 2018, indicating a 3.4-fold increase. Across the three survey periods, women yielded rates nearly three times higher than men. Lifetime prevalence grew the most among adolescents aged 13-15 years. Compared to the other respondents, the odds of lifetime suicide attempts proved seven times as high for those who had been sexually abused during their childhood, five times as high for those who had been diagnosed with a depressive disorder, three times as high for those who had suffered physical aggression and twice as high for those who had smoked 100+ cigarettes in their lifetimes and those who consumed alcohol. CONCLUSION: The sharp increase in suicide attempts in Mexico calls for an urgent public-health response via universal and targeted interventions supported by national policy and sustained federal funding.

Evidence for the Factorial Validity of the Beck Hopelessness Scale in Spanish with Clinical and non-Clinical Samples / Evidencias de validez factorial de la Escala de desesperanza de Beck en español con muestras clínicas y no clínicas

Abstract The purpose of the present study is to evaluate the internal structure of the Spanish adaptation of the Beck Hopelessness Scale (Beck et al., 1974) given its usefulness and relevance in the prediction of suicidal behaviors. The responses to the scale of 1260 university students (M = 4.79, SD = 4.29) and of a clinical sample in which 150 young people with suicide attempt of high lethality (M = 8.51, SD = 2.38) participated were analyzed. The internal structure of the scale is examined by confirmatory factor analysis (CFA) in three phases. In the first phase, the original model is compared with four models found in the different adaptations to Spanish; in the second phase, models that analyze acquiescence are taken into account, and in the third phase, a cross-validation of those models with a clinical population is made. The results indicate that the scale is one-dimensional both in the case of clinical samples (χ2 = 154.84, gl = 135, p <0.001, CFI = 0.99, TLI = 0.99, RMSEA = 0.03), as well as in the general population. However, for the latter, a method factor was added for the treatment of acquiescence (χ2 = 252.14, gl = 134, p <0.001, CFI = 0.95, TLI = 0.94, RMSEA = 0.03). The results show the importance of using analyzes and models that consider the nature of the data and the characteristics of the sample to provide more solid evidence for construct validity.

Resumen El propósito del presente estudio fue evaluar la estructura interna de la adaptación al español de Escala de Desesperanza de Beck et al. (1974), dada su utilidad y relevancia en la predicción de conductas suicidas. Para esto, se analizaron las respuestas a la escala de 1260 estudiantes universitarios (M = 4.79; DT = 4.29) y de una muestra clínica en la que participaron 150 jóvenes con intento de suicidio de alta letalidad (M = 8.51; DT = 2.38). Se examinó la estructura interna por medio del Análisis factorial confirmatorio (AFC) en tres fases: en la primera, se comparó el modelo original con cuatro modelos encontrados en las diferentes adaptaciones al español; en la segunda, se tomaron en cuenta modelos que analizan la aquiescencia; y en la tercera, se hizo una validación cruzada de esos modelos con población clínica. Los resultados señalan que la escala es unidimensional tanto en el caso de las muestras clínicas(χ2 = 154.84, gl = 135, p < 0.001, CFI = 0.99, TLI = 0.99, RMSEA = 0.03) como en la población universitaria; sin embargo, a esta última se le añadió un factor de método para el tratamiento de la aquiescencia (χ2 = 252.14, gl = 134, p < 0.001, CFI = 0.95, TLI = 0.94, RMSEA = 0.03). Los resultados muestran la importancia de utilizar análisis y modelos que consideren la naturaleza de los datos y las características de la muestra para aportar evidencias más sólidas para la validez de constructo.

Depresión en adolescentes. Un problema oculto para la salud pública y la práctica clínica / Depression among adolescents. A hidden problem for public health and clinical practice

La depresión constituye un grave problema de salud pública que requiere mayor y mejor atención. En el presente ensayo revisamos el panorama epidemiológico de la depresión en adolescentes de México y discutimos algunas estrategias para su detección temprana y atención oportuna.La sintomatología depresiva es prevalente en jóvenes y adultos en México, como en muchos otros países, con una mayor proporción de casos entre las mujeres. Los jóvenes en condiciones socio-urbanas más conflictivas muestran tasas más elevadas de depresión.Si bien los trastornos depresivos son más prevalentes en las mujeres, en los hombres sus consecuencias pueden tener repercusiones de gravedad aún mayores que en las mujeres. El estigma hacia la depresión en los hombres puede conducir a que se intente enmascarar los síntomas mediante conductas de alto riesgo. Las mujeres tienen mayores tasas de intento de suicidio, pero en los hombres los intentos son más letales. Las tasas de suicidio consumado en varones son más altas en la mayoría de los países del mundo, y México no es la excepción. Pese a las barreras y escasos recursos en las instituciones de salud y educación, será necesario continuar desarrollando alternativas que permitan una mejor atención de la problemática de salud mental en la población joven, aun cuando sus necesidades no puedan ser expresadas directamente o que los motivos de consulta sean "otros", frecuentemente enmascarados por conductas problemáticas, como la violencia y las adicciones, entre otras.

Depression is an important public health problem that requires more and better attention. In the present work we review epidemiologic studies of depression among adolescents in Mexico and discuss strategies that may help in earlier identification and referral of potential cases for timely care.In summary, depressive symptoms are prevalent among adolescents and adults in Mexico as in many other countries, with a higher ratio of female cases. Young people experiencing the most challenging socio-urban situations have higher rates of depression.Even though depressive disorders are more prevalent among females, consequences may be even worse for males. The authors posit that, among males, stigma attached to depression might lead to attempts to hide depressive symptoms by masking them through high-risk behaviors (e.g., alcohol, drug use, and violence, among others). Women may have higher rates of suicide attempts, but the case-fatality rate of suicide attempts is higher among males.Despite of barriers and resource scarcity among healthcare and educational institutions, it is necessary to continue to develop alternatives that will lead to better attention of mental health issues among the youth, even when their mental health needs are not expressed directly or their chief complaints are in regard to "other" health issues.
