The purpose of this study was to analyze psychometric properties of the Spanish version of Attitudinal Beliefs Questionnaire about Suicidal Behavior CCCS-18 (Ruiz, Navarro-Ruiz, Torrente, & Rodríguez, 2005). The participants were 277 subjects, 81.2% (225) women and 18.8% (52) men. The average age was 39.95 years old (SD = 15.9). A confirmatory factor analysis was performed to test the adequacy of the four-factor model proposed by the authors. As a result it was obtained a three-factor model (χ2/df = 1.96; CFI = .98; sRMR = .060; RMSEA = .059), with indices reflecting adequate goodness of fit. The reliability of the test using the omega coefficient showed satisfactory values (ω h = .95, CI 95% = [.94, .96]). The results indicate a close relation between the CCCS-18 dimensions and the suicidal tendency, showing discriminant validity properties. Predictive validity was also found in the significant correlations between the measures obtained in the questionnaire and a risk index resulting from the suicidal ideation predictor variables that were part of a logistic regression equation; CCCS-18 (r = .26, p < .001), F1, Legimization and terminal disease (r = .163, p < .01), F2, Moral dimension (r = .22, p < .001) and F3, Suicide itself (r = .252, p < .001).
Conclusions: The CCCS-18 shows reliability and validity, as well as being a test of easy and brief application.
