We examined associations between Latino adolescents' school engagement and their likelihood of disclosing suicidal ideation (SI) to adults and of asking for help for SI. A first set of analyses was conducted on a total sample of 14 high schools, and a second set of analyses was conducted on 8 "Latino-representative" high schools. The criterion for Latino representation was that [greater than or equal to] 10% of the school's total student population was Latino. Across all 14 high schools, 17% (110/663) of Latino students reported SI in the past year, compared to 13% (359/2,740) of non-Hispanic White students and 11% (78/719) of African American students. Of Latino students with SI, 24% (26/110) told an adult and 35% (38/110) sought help. In the 8 Latino-representative schools, higher levels of reported school engagement were associated with a greater likelihood of seeking help (OR = 6.17) and disclosure of SI to an adult (OR = 7.64) for Latino males. For Latinas, however, school engagement was not associated with either disclosure of SI to an adult or seeking help. Additional research is needed to clarify the processes, including social connectedness, that contribute to the disclosure of and help-seeking for SI among Latino adolescents.
