Sources of Strength is the first suicide prevention program involving peer leaders to enhance protective factors associated with reducing suicide at the school population level.

To develop and refine interventions to prevent youth suicide, knowledge is needed about specific processes that reduce risk at a population level. Using a cross-sectional design, the present study tested hypotheses regarding associations between self-reported suicide attempts, emotion regulation difficulties, and positive youth-adult relationships among 7,978 high-school students (48.6% male, 49.9% female) in 30 high schools from predominantly rural, low-income communities. 683 students (8.6%) reported a past-year suicide attempt. Emotion regulation difficulties and a lack of trusted adults at home and school were associated with increased risk for making a past-year suicide attempt, above and beyond the effects of depressive symptoms and demographic factors. The association between emotion regulation difficulties and suicide attempts was modestly lower among students who perceived themselves as having higher levels of trusted adults in the family, consistent with a protective effect. Having a trusted adult in the community (outside of school and family) was associated with fewer suicide attempts in models that controlled only for demographic covariates, but not when taking symptoms of depression into account. These findings point to adolescent emotion regulation and relationships with trusted adults as complementary targets for suicide prevention that merit further intervention studies. Reaching these targets in a broad population of adolescents will require new delivery systems and “option rich” intervention designs.

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9 % female, 46.9 % male; racial distribution 79.5 % Caucasian, 11.9 % Hispanic/Latino, and 3.6 % Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents’ help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14 %) students reporting SI, only 23 % told an adult, 29 % sought adult help, and 15 % did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students’ increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students’ perceptions of the availability and capability of adults to help them, and strengthening students’ understanding of how existing resources can help them cope.

Validated measures that can be administered to school populations are needed to advance knowledge of help-seeking processes and to evaluate suicide prevention programs that target help-seeking. With 6,370 students from 22 high schools, we assessed the psychometric properties of three brief measures: Help-Seeking Acceptability at School, Adult Help for Suicidal Youth, and Reject Codes of Silence. Internal consistency coefficients ranged from 0.64 – 0.84. In support of construct validity, lower scores on each scale were associated with more maladaptive coping norms; and for each one unit increase on each scale, students were one-third to one-half as likely to report suicidal ideation, suicide attempts and elevated depression.

Developing science-based communication guidance and positive-themed messages for suicide prevention are important priorities. Drawing on social learning and elaboration likelihood models, we designed and tested two positive-focused presentations by high school peer leaders delivered in the context of a suicide prevention program (Sources of Strength). Thirty six classrooms in four schools (N=706 students) were randomized to: (a) peer leader modeling of healthy coping, (b) peer leader modeling plus audience involvement to identify trusted adults, or (c) control condition. Students’ attitudes and norms were assessed by immediate post-only assessments. Exposure to either presentation enhanced positive coping attitudes and perceptions of adult support. Students who reported suicide ideation in the past 12 months benefited more than non-suicidal students. Beyond modeling alone, audience involvement modestly enhanced expectations of adult support, congruent with the elaboration likelihood model. Positive peer modeling is a promising alternative to communications focused on negative consequences and directives and may enhance social-interpersonal factors linked to reduced suicidal behaviors.
