Interpersonal violence and suicide risk: Examining buffering effects of school and community connectedness.

Background: Exposure to interpersonal violence is associated with elevated suicide risk. Preventing suicide among high-risk adolescents is most often discussed from a clinical treatment perspective, resulting in a gap in research examining whether school and community connectedness can buffer the relationships between forms of interpersonal violence and suicide risk in clinical samples of adolescents. Methods: Baseline data from 294 adolescents who received substance use treatment were analyzed to help fill this gap in research. Adolescents in this sample were at greater risk for suicidal thoughts and behaviors given their histories of substance use disorders and high rates of interpersonal violence, with 57% reporting experiencing at least one form of abuse/violence. Independent variables included lifetime exposure to physical abuse, sexual abuse, and weapon violence; moderators included various measures of school and community connectedness. Multinomial logistic regression models were estimated to examine the main and interaction effects predicting a three-category measure of suicide risk: non-suicidal, suicidal ideation only, and prior suicide attempts. Results: Sexual abuse survivors had the highest predicted probability of a prior suicide attempt when reporting lower levels of teacher support, school-based positive peer interactions, or neighborhood social connection, but at higher levels of these protective factors, their predicted probability was similar to those not exposed to sexual abuse. The same protective pattern was observed for physical abuse survivors with high neighborhood social connection. Conclusion: The buffering effects observed in this study identified dimensions of school and community social connectedness as protective factors for youth exposed to abuse. Although promoting social connectedness is often cited as a universal suicide prevention approach, tailored efforts to enhance connectedness within this population may also be a promising secondary prevention strategy. Thus, in addition to clinical treatment, more emphasis should be placed on systems-level approaches to reducing risk among youth most vulnerable to suicide.

Investigating the Interplay Between Mental Health Conditions and Social Connectedness on Suicide Risk: Findings from a Clinical Sample of Adolescents.

This study examined whether school and community connectedness buffer the relationships between mental health conditions and suicide risk in a clinical sample of adolescents with histories of substance use disorders. Data from 294 adolescents were examined, with approximately 58% reporting lifetime suicidal ideation and/or prior attempts. Multinomial logistic regression was used to examine main and interaction effects on a three-category measure of suicide risk. Depression severity and panic disorder were associated with elevated suicidal ideation risk, whereas disordered eating was associated with elevated risk of attempts. Higher school-based positive peer interactions, school safety, and neighborhood social connection levels were associated with reduced suicide attempt risk. Moderation analyses revealed that high neighborhood social connection levels may partially mitigate the elevated likelihood of attempting suicide associated with disordered eating. Findings suggest clinical populations of adolescents may benefit from approaches aiming to promote social connectedness, further supporting a comprehensive approach to suicide prevention.

Examination of promotive and protective effects on early adolescent prosocial behavior through a bioecological lens.

Introduction: Prosocial behavior during childhood has been associated with numerous positive developmental and behavioral outcomes in adolescence and adulthood. Prosocial behavior, which includes cooperation and helping others, develops within a bioecological context. Considering it through such a lens enhances the understanding of the roles of different bioecological factors in its development. Methods: Using data from a longitudinal study of adopted children and children reared with their biological parents, this paper examined if positive aspects of a child's bioecological system at age 7 predict prosocial behavior in early adolescence (age 11), and whether these bioecological factors could offset risk due to biological family psychopathology and/or maternal prenatal substance use. The analyses incorporated variables from different levels of Bronfenbrenner's bioecological model (the individual, microsystem, exosystem, and macrosystem) and examined the promotive, and potentially protective, effect of each contextual factor, while also considering their interplay with biological family psychopathology and prenatal substance use. Results: Results from linear regression models indicated that the microsystem variable of parental warmth at age 7 had a promotive effect on age 11 prosocial behavior. Further, in addition to its main effect, parental warmth was protective against maternal substance use during pregnancy when children were raised with their biological parent (s). Household type (biological family) and biological family internalizing psychopathology were the only other significant predictors in the model, with each associated with lower prosocial behavior at age 11. Discussion: Study results extend prior work on the benefits of parental warmth on child outcomes by employing a strength-based, bioecological approach to the development of prosocial behavior during early adolescence and examining "for whom" the effects of parental warmth are most protective.

The effect of mild to moderate COVID-19 infection on the cardiorespiratory fitness of firefighters.

Introduction: An adequate level of cardiorespiratory fitness (CRF) is critical for firefighters to perform the strenuous and physiologically demanding work of firefighting safely and effectively. The coronavirus disease 2019 (COVID-19) has been shown to negatively impact CRF in both the acute phase and longer-term following infection. This study aimed to determine changes to the CRF of firefighters pre- to post-mild to moderate COVID-19 infection and to investigate the impact of days past COVID-19 infection on change in CRF. Methods: CRF measures from cardiopulmonary exercise testing (CPET) at annual occupational health exams that occurred pre-COVID-19 infection in 2019 were obtained for firefighters from seven Arizona fire departments. Measures were compared to CPET evaluations from annual health exams the following year in a cohort of firefighters who self-reported mild to moderate illness following COVID-19 infection between exams. Results: Among a cohort of 103 firefighters, mean age 40 ± 9 years, CRF [as measured by peak oxygen consumption (VO2)] declined by an average of 2.55 ml·kg-1·min-1 or 7.3% (d = -0.38, p < 0.001) following COVID-19 infection (mean time from COVID-19 infection to CPET was 110 ± 78 days). The number of days past COVID-19 infection showed a small, yet significant, relationship to peak VO2 (r = 0.250, p = 0.011). Estimated marginal effects indicated that when biological sex, age, and BMI are controlled for, predicted peak VO2 returned to pre-COVID-19 values ~300 days after COVID-19 infection. Conclusion: Peak VO2 (ml·kg-1·min-1) declined 7.3% among firefighters an average of 110 days past reporting mild to moderate COVID-19 infection. This decrease has implications for the operational readiness and safety of firefighters.

Differential Predictors of Suicidal Ideation and Suicide Attempts: Internalizing Disorders and Substance Use in a Clinical Sample of Adolescents.

Objective: Dually diagnosed adolescents are a high-risk population for experiencing suicidal thoughts and behavior. Given that research suggests risk factors for suicidal ideation and suicide attempts may be different, this study examined whether internalizing disorder severity, frequency of substance use, and the interaction between them differentiated adolescents who attempted suicide from those who ideated. Methods: Baseline data from 287 adolescents who received formal substance use disorder (SUD) treatment were used in this analysis. Major depressive disorder (MDD) and generalized anxiety disorder (GAD) severity as well as past-3 month use of alcohol, cannabis, and other illicit drugs were considered. The outcome of interest was a three-category measure of suicide risk: no reported suicidal ideation or attempts, suicidal ideation only, and suicide attempts. Results: Over half of the sample disclosed prior suicidal ideation (30.0%) or attempts (27.9%). Multinomial logistic regression models indicated more severe MDD and GAD symptomology differentiated ideators from non-suicidal adolescents, but internalizing disorder severity did not differ between ideators and attempters. Substance use frequency did not differ between suicide risk groups. MDD severity and frequency of alcohol use interacted to increase the risk of attempts, yet the effects were minimal. Instead, prior weapon violence victimization and sexual abuse were the largest differentiators between attempters and ideators. Conclusions: Findings suggest that internalizing disorder severity and prior traumatic experiences put adolescents with SUD histories at higher risk of suicidal thoughts and behaviors. Thus, integrating evidence-based suicide prevention and intervention efforts into SUD treatment is critical, particularly for dually diagnosed adolescents who meet these risk profiles. Psychotherapy and medication may help curtail the development of ideation by reducing symptoms of MDD and GAD, whereas adolescents with prior traumatic experiences may benefit from additional treatments shown to lower risk of suicide attempts.
