Purpose <p>Hispanic/Latinx (H/L) youth experience elevated rates of suicidal ideation, yet often face barriers to care. Suicide stigma, suicide literacy, and acculturation can shape beliefs about mental health and responses to crises, and in turn, influence parents’ roles as “gatekeepers” to mental health care services for their children. Using a sample of H/L parents in the United States, this study examined how suicide stigma, suicide literacy, and acculturation relate to parents’ confidence in obtaining emergency psychological services for their child (self-efficacy).</p> Methods <p>238&#xa0;H/L parents (<i>M</i>_age = 36.27, 55.95% female) were asked to complete self-report surveys. Pearson’s correlations, hierarchical linear regression, and indirect effects analyses were conducted. Regression analyses controlled for parent depression symptoms, suicidal ideation, age, sex, and education, as well as child’s prior service use.</p> Results <p>Parental self-efficacy was significantly correlated with lower suicide stigma, higher suicide literacy, and higher acculturation. Regression analyses indicated higher stigma was associated with lower self-efficacy, while higher acculturation was associated with greater self-efficacy. Suicide literacy was not uniquely associated with self-efficacy when other predictors were included, but demonstrated a significant indirect effect on the relationship between acculturation and self-efficacy.</p> Conclusions <p>Results suggest stigma may hinder, while acculturation may facilitate H/L parents’ help-seeking. Additionally, suicide literacy partially explains the acculturation-self-efficacy link and may be a modifiable target for enhancing access to care for at-risk families.</p>
