Rationale Translation, adaptation and cross‐cultural validation of instruments or scale to measure concepts of interest among different populations can facilitate sharing of knowledge and advance cross‐cultural research globally, especially in countries with diverse populations. Aims and objectives This is a two‐phase study aiming to: (1) translate, adapt and cross‐validate the 24‐item English version of Caring Behaviors Inventory into Greek; and (2) evaluate the psychometric properties of the Greek version (CBI‐GR). Methods A descriptive correlational design was used to conduct the study. The procedure involved professional translators, committee approach, and a sample of nurses and patients. The psychometric evaluation of the CBI‐GR used a sample of 245 Greek and Cypriot medical‐surgical nurses. Data analyses comprised internal consistency reliability (Cronbach's alpha coefficient), stability (test–retest) reliability, item analysis and confirmatory factor analysis. Results The Cronbach's alpha for the overall CBI‐GR was 0.92 and ranged from 0.76 to 0.87 for the subscales. Correlation coefficients between test and retest for the overall CBI‐GR was r = 0.83 and ranged from r = 0.69 to 0.78 for its subscales. Confirmatory factor analysis of the scale supports its four‐factor structure and the model indexes were adequate: X 2 (239) = 515.54, P < 0.001; comparative fit index = 0.91; incremental fit index = 0.91; and Tucker Lewis index = 0.90; parsimony normed fit index = 0.73; parsimony comparative fit index = 0.79; and root mean square of approximation = 0.07. Conclusions The CBI‐GR is comparable with the original 24‐item English version of the CBI and it is suitable to measure nurse caring among Greek‐speaking nurses. Further psychometric testing of the instrument among nurses and patients is warranted.
