Factorial invariance of the Questionnaire for evaluating School Social Climate in Chilean and Colombian students

This study aims to determine the degree of psychometric equivalence of the questionnaire for evaluating School Social Climate in Chilean and Colombian adolescents. Using an intentional non-probability sampling, the adolescents were selected from 11 public schools and subsidised private schools in Chile and Colombia. The study involved 1,233 adolescents of both sexes, with a mean age of 14.82 years (SD = 1.83). The results from confirmatory factor analysis ratified the correlated two-factor structure in the Chilean sample Satorra Bentler-schisquare(76) = 175.664, P < .001; comparative fit index = .956; Tucker-Lewis index = .948; root mean square error of approximation = .044 (90% CI = .035-. 052), and in the Colombian sample Satorra Bentler's chi-square(76) = 131.508, P < .001; comparative fit index = .942; Tucker-Lewis index = .931; root mean square error of approximation = .037 (90% CI = .026-.047). Invariance factorial analysis showed that the cross cultural level of the instrument is plausible at invariance configuration level (M1 = Delta Satorra Bentler's chi-square = 35.583; Delta gl = 12; P < .001; Delta comparative fit index = .007). The resulting scale depicted adequate indices of reliability for internal consistency and homogeneity. (C) 2016 Fundacion Universitaria Konrad Lorenz. Published by Elsevier Espana, S.L.U.
