The study used a methodological design to adapt a Turkish translation and validate the Bolton Compassion Strengths Indicators scale.

The sample of the study consisted of 500 nursing students. Partial least squares structural equation modelling was used to analyze the construct and internal validiy. The values of average variance explained were analyzed for convergent validity. Tukey’s test of additivity examined the additivity, and Hotelling’s T2 test examined the mean difference between items. Internal consistency and test–retest reliability were ensured for reliability. Test and retest scores were compared by applying the paired samples t-test and Wilcoxon test, and the fit was analyzed through the intra-class correlation coefficient.

The Turkish version of the scale consisted of 34 items and 8 subscales. The Cronbach’s alpha coefficient of the overall scale was 0.954. The scale was highly reliable and displayed psychometric solid properties.

It has been determined that the Turkish version of the Bolton Compassion Strengths Indicators scale is a comprehensive, easy-to-understand measurement tool with a broad perspective that can be safely applied to future nurse candidate students. The scale has been evaluated as a reliable measurement tool that can provide cross-cultural measurement.
