Note. Measures of adolescents’ pretest and posttest attitude, self-efficacy and behavioral intention related to workplace safety and health. Pre = pretest; Post = posttest; ATT = attitude; SE = self-efficacy; BI = behavioral intentions; KNOW = knowledge. WLSMV = weighted least squares with mean and variance correction estimation; SRMR = standardized root mean square residual; CFI = comparative fit index; TLI = Tucker-Lewis index of incremental fit; RMSEA = root mean square error of approximation. All models were statistically significant (p < .001).
