Interpersonal negative life events (NLEs) have been linked to risk for suicidal thoughts and behaviors. However, little is known about how this risk is conferred over the short term and the mechanisms linking interpersonal NLEs to suicide risk, particularly in adolescents. This study used an intensive longitudinal design to examine thwarted belongingness with family and friends as potential mechanisms linking interpersonal NLEs to suicidal thoughts. Forty-eight adolescents (Mage = 14.96 years; 64.6% female, 77.1% White), who recently received acute psychiatric care for suicide risk, were followed intensely for 28 days after discharge. Smartphone-based ecological momentary assessment was used to measure presence of interpersonal NLEs at the day level, fluctuations in thwarted belongingness with family and friends (separately) within day, and fluctuations in suicidal thoughts within day. A multi-level structural equation model was utilized to examine family thwarted belongingness and friend thwarted belongingness as parallel mediators in the relationship between interpersonal NLEs and next-day suicidal thoughts. Significant direct effects were observed between interpersonal NLEs and family thwarted belongingness, family thwarted belongingness and suicidal thoughts, and friend thwarted belongingness and suicidal thoughts. In addition, family, but not friend, thwarted belongingness significantly mediated the association between interpersonal NLEs and next-day suicidal thoughts. Interpersonal NLEs predicted greater suicidal thoughts over the short term (next day) in high-risk adolescents. Findings suggest how interpersonal NLEs may confer risk for suicidal thoughts – by reducing feelings of family belongingness. Future research is needed to examine how modifying belongingness may reduce suicide risk in adolescents. [ABSTRACT FROM AUTHOR]

Objective: The study purpose was to examine the feasibility and acceptability of intensive ecological momentary assessment (EMA) among high-risk adolescents with suicidal thoughts and behaviors following discharge from acute psychiatric care. Method: Fifty-three adolescents, 12–18 years old, and their parents, were recruited following discharge from acute psychiatric care for suicide risk. The study included a baseline assessment (adolescent and parent), 28 days of EMA surveys (5x per day) and wrist actigraphy (adolescent), and an interview at the end of the 28-day monitoring period (adolescent). Adolescents' outpatient clinicians were also surveyed about the study. Results: Study feasibility was indicated by a reasonable enrollment rate, high adherence to wearing the actigraphy device, and good adherence to EMA surveys (highest in the first week with significant drop-off in subsequent weeks). Adolescents reported their overall experience in the study was positive, the questions were understandable, their responses to questions were generally accurate, and the surveys were minimally burdensome. The study procedures did not appear to be iatrogenic; suicide attempts and rehospitalizations were not study related and occurred at a rate comparable to other adolescents at the recruitment site. Adolescents' clinicians reported that the study was somewhat positive and minimally burdensome for them, and somewhat positive for their patients and families. Conclusions: This study demonstrated that intensive EMA designs are feasible and acceptable among high-risk suicidal youth following acute psychiatric care. Specific procedures are provided for keeping adolescents safe during intensive EMA studies, including detailed information about the risk and safety monitoring plan. [ABSTRACT FROM AUTHOR]

Suicide is a leading cause of death among youth worldwide. 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.
