Comparison of changes of the total cultural competence and scores of six CDQNE–R subscales between the control and intervention groups before and after the training programTotal of culturalCompetenceBold p-values are significant at level of ≤ 0.05.Effect size (ES): 0-0.2 = small effect, 0.2–0.5 = moderate effect, > 0.5–0.7 = large effect, and > 0.7 = very large effectMoreover, the intervention group had higher scores in all subscales of CDQNE-R than the control group, so that the effect sizes of subscales in the intervention group were between 0.53 and 1.09 after training.The within-group comparisons of the intervention group showed that the total scores of CDQNE-R and its subscales improved after training compared with before. According to the scoring of CDQNE–R based on Benner’s theory, the intervention group promoted from being culturally competent to culturally proficient.The mean differences showed that training program had the highest effect on the cultural knowledge subscale (M diff = 0.63) and the lowest effect on cultural awareness subscale (M diff = 0.35).In addition, the multivariate linear regression (Forward stepwise method) was conducted to eliminate the impact of confounding variables on the cultural competence (such as age, gender, marital status, employment status, degree, residence in Kerman province, location, majors, history of attendance in cultural competence training courses, and curriculum status in terms of providing culturally congruent care). The results showed that these variables were not significant predictors of cultural competence among nurse educators in this study (Table
