Suicidal behaviors questionnaire-revised: Adaptation and psychometric properties of the Brazilian version

Suicidal behaviors are a significant concern in Latin American countries. However, validated scales in Brazil do not address all behaviors on the suicide spectrum. We aimed to adapt the Suicidal Behaviors Questionnaire-Revised (SBQ-R) for Brazil. The SBQ-R was independently translated, back-translated, and evaluated by experts-two thousand eight hundred ninety-eight participants (68.30% women; M = 27.42; A = 18-69) from Brazil. The SBQ-R items presented adequate reliability (ω = .86). Confirmatory factor analysis (CFA) confirmed the construct validity (χ²(df) = 52.707(2), p<.001; CFI = .997; TLI = .992; RMSEA = .052; SRMR = .024). Multigroup CFA indicated that the SBQ-R is invariant for gender, sexual orientation, race, and education level. The SBQ-R has convergent validity for depression (r = 0.61), anxiety (r = 0.49), stress (r = 0.49), impulsivity (r = 0.40), hopelessness (r = 0.60) and divergent validity, with gender and sexual minorities showing higher levels of suicidal behaviors. The Brazilian SBQ-R is designated for use by Brazilian adults. Future studies must investigate the predictive validity of the SBQ-R in clinical samples.
