Life is precious: A quasi-experimental study of a community-based program to prevent suicide among Latina adolescents in New York City

Introduction Rising rates of suicidal thoughts and behaviors (STBs) among U.S. Latina adolescents urgently need attention. Life is Precious (LIP) is a culturally responsive, community-based, afterschool-model program offering wellness-support services to supplement outpatient mental health treatment for Latina adolescents experiencing STB's. This 12-month quasi-experimental pilot study explored LIP's impact on clinical outcomes. Methods Latina adolescents newly enrolled in LIP and receiving outpatient treatment (n = 31) and those newly starting outpatient treatment only (n = 12; Usual Care) were assessed for Suicidal Ideation (Suicidal Ideation Questionnaire; SIQ) and depressive symptoms (Patient Health Questionnaire-9). We estimated differences in mean scores using longitudinal linear mixed models and adjusted risk ratios (ARRs) of SIQ-25%, SIQ-50%, and PHQ-9-5-point improvements using exact logistic models. Results The direction of the estimated impact of LIP was positive [differences (95% CIs): −15.5 (−34.16, 3.15) for SIQ; −1.16 (−4.39, 2.07) for PHQ-9], with small-to-moderate nonsignificant effect sizes (0.19–0.34). LIP participants saw two to three times higher prevalence than controls of SIQ-25%, SIQ-50%, and PHQ-9-5-point improvements; ARRs (95% CIs) were 1.91 (0.61, 3.45), 3.04 (0.43, 11.33), and 1.97 (0.44, 5.07), respectively. Suicidal behaviors also decreased in LIP. Conclusion The effects of LIP were in positive directions across clinical outcomes, warranting further research on its effectiveness in decreasing STBs.
