The purpose of the current review was to examine recent cross-national trends in suicide mortality rates among 10- to 19-year-olds. This study extracted suicide mortality data from the World Health Organization's (WHO) Mortality Database for the most recent year (since 2010) from any country with available high-quality data (as defined by the WHO's guidelines). Data on access to lethal means (firearms, railways) and measures of economic quality (World Bank Income Group) and inequality (Gini coefficients) were obtained from publicly available data sources. Cross-national suicide mortality rates in youth were heterogeneous. The pooled estimate across all ages, sexes, and countries was 3.77/100,000 people. The highest suicide rates were found in Estonia, New Zealand, and Uzbekistan. Suicide rates were higher among older compared with younger adolescents and higher among males than females. The most common suicide methods were hanging/suffocation and jumping/lying in front of a moving object or jumping from a height. Firearm and railway access were related to suicide deaths by firearms and jumping/lying, respectively. Economic quality and inequality were not related to overall suicide mortality rates. However, economic inequality was correlated with a higher ratio of male:female suicides. This study provides a recent update of cross-national suicide trends in adolescents. Findings replicate prior patterns related to age, sex, geographic region, and common suicide methods. New to this review are findings relating suicide method accessibility to suicide mortality rates and the significant association between income inequality and the ratio of male:female suicide. Future research directions include expanding the worldwide coverage to more low- and middle-income countries, examining demographic groupings beyond binary sex and to race/ethnicity within countries, and clarifying factors that account for cross-national differences in suicide trends.

Annual Research Review: Suicide among youth - epidemiology, (potential) etiology, and treatment / Christine B. CHA in Journal of Child Psychology and Psychiatry, 59-4 (April 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-4 (April 2018) . - p.460-482 Titre : Annual Research Review: Suicide among youth - epidemiology, (potential) etiology, and treatment Type de document : Texte imprimé et/ou numérique Auteurs : Christine B. CHA, Auteur ; P. J. FRANZ, Auteur ; M. Guzman E, Auteur ; C. R. GLENN, Auteur ; E. M. KLEIMAN, Auteur ; M. K. NOCK, Auteur Article en page(s) : p.460-482 Langues : Anglais (eng) Mots-clés : Suicide  correlates  prevention  risk factors  treatment Index. décimale : PER Périodiques Résumé : BACKGROUND: Suicide is a leading cause of death and a complex clinical outcome. Here, we summarize the current state of research pertaining to suicidal thoughts and behaviors in youth. We review their definitions/measurement and phenomenology, epidemiology, potential etiological mechanisms, and psychological treatment and prevention efforts. RESULTS: We identify key patterns and gaps in knowledge that should guide future work. Regarding epidemiology, the prevalence of suicidal thoughts and behaviors among youth varies across countries and sociodemographic populations. Despite this, studies are rarely conducted cross-nationally and do not uniformly account for high-risk populations. Regarding etiology, the majority of risk factors have been identified within the realm of environmental and psychological factors (notably negative affect-related processes), and most frequently using self-report measures. Little research has spanned across additional units of analyses including behavior, physiology, molecules, cells, and genes. Finally, there has been growing evidence in support of select psychotherapeutic treatment and prevention strategies, and preliminary evidence for technology-based interventions. CONCLUSIONS: There is much work to be done to better understand suicidal thoughts and behaviors among youth. We strongly encourage future research to: (1) continue improving the conceptualization and operationalization of suicidal thoughts and behaviors; (2) improve etiological understanding by focusing on individual (preferably malleable) mechanisms; (3) improve etiological understanding also by integrating findings across multiple units of analyses and developing short-term prediction models; (4) demonstrate greater developmental sensitivity overall; and (5) account for diverse high-risk populations via sampling and reporting of sample characteristics. These serve as initial steps to improve the scientific approach, knowledge base, and ultimately prevention of suicidal thoughts and behaviors among youth.

Implicit cognition about self-injury predicts actual self-injurious behavior: results from a longitudinal study of adolescents / Catherine R. GLENN in Journal of Child Psychology and Psychiatry, 57-7 (July 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-7 (July 2016) . - p.805-813 Titre : Implicit cognition about self-injury predicts actual self-injurious behavior: results from a longitudinal study of adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Catherine R. GLENN, Auteur ; Evan M. KLEIMAN, Auteur ; Christine B. CHA, Auteur ; Matthew K. NOCK, Auteur ; Mitchell J. PRINSTEIN, Auteur Article en page(s) : p.805-813 Langues : Anglais (eng) Mots-clés : Self-injury  self-harm  adolescence  longitudinal studies  assessment Index. décimale : PER Périodiques Résumé : Background The implicit association hypothesis of nonsuicidal self-injury (NSSI) proposes that individuals who engage in self-injury develop, over time, strong associations between themselves and NSSI, and their identification with this behavior guides their future selection of NSSI to cope. Prior research has established a relationship between implicit NSSI associations (using an Implicit Association Test for Self-Injury) and engagement in NSSI. However, previous studies have been small and cross-sectional, and thus underpowered to examine the nature of this association and the extent to which implicit associations predict the persistence of NSSI. Methods This study builds on previous research in a prospective, longitudinal examination of implicit self-identification with NSSI in a large sample of middle school students. NSSI behavior and implicit NSSI associations were assessed annually in school at three time points. Results Adolescents who engaged in NSSI exhibited stronger implicit self-identification with NSSI than adolescents who did not engage in NSSI. Moreover, implicit NSSI identification was stronger among adolescents who engaged in cutting, frequent NSSI, and recent NSSI. A reciprocal association was observed between NSSI frequency and implicit NSSI identification over 1 year. Notably, implicit NSSI identification uniquely and prospectively predicted engagement in NSSI over the subsequent year. Conclusions Implicit self-identification with NSSI may track both trait- and state-related changes in the behavior and, importantly, may help predict continued engagement in NSSI.

Implicit identification with death predicts change in suicide ideation during psychiatric treatment in adolescents / Catherine R. GLENN in Journal of Child Psychology and Psychiatry, 58-12 (December 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-12 (December 2017) . - p.1319-1329 Titre : Implicit identification with death predicts change in suicide ideation during psychiatric treatment in adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Catherine R.

AUERBACH, Auteur Article en page(s) : p.1319-1329 Langues : Anglais (eng) Mots-clés : Suicide  suicidal behavior  adolescence  information processing  prediction Index. décimale : PER Périodiques Résumé : Background Suicidal thoughts and behaviors are major public health concerns in youth. Unfortunately, knowledge of reliable predictors of suicide risk in adolescents is limited. Promising research using a death stimuli version of the Implicit Association Test (Death IAT) indicates that stronger identification with death differs between adults with and without a history of suicidal thoughts and behaviors and uniquely predicts suicide ideation and behavior. However, research in adolescents is lacking and existing findings have been mixed. This study extends previous research by testing whether implicit identification with death predicts changes in suicide ideation during psychiatric treatment in adolescents. Methods Participants included 276 adolescents, ages 13–19, admitted to a short-term residential treatment program. At hospital admission and discharge, adolescents completed the Death IAT and measures of recent suicidal thoughts. Results At admission, implicit identification with death was associated with recent suicide ideation, but did not differ between those who engaged in prior suicidal behavior and those who did not. Prospectively, adolescents' implicit identification with death at admission significantly predicted their suicide ideation severity at discharge, above and beyond explicit suicide ideation. However, this effect only was significant for adolescents with longer treatment stays (i.e., more than 13 days). Conclusions Implicit identification with death predicts suicidal thinking among adolescents in psychiatric treatment. Findings clarify over what period of time implicit cognition about death may predict suicide risk in adolescents.
