Purpose of this research study was to adapt the instrument called ‘Self-efficacy and concerns about STEM education’ developed by Geng, Jong, and Chai (2019) for pre-service teachers into Turkish. This instrument includes two sub-scales: self-efficacy and stages of concerns. In order to measure the stages of concern, the instrument was designed by five sub-dimensions: evaluation, information, management, consequence and refocusing. For the reliability and validity of the study, exploratory factor analysis, test-retest and confirmatory factor analysis were applied. Results of the analysis revealed that adapted instrument had different factor loading in comparison to original instrument. The Cronbach’s alpha coefficients were calculated as .94 for the instrument. For the sub-scales, self-efficacy, information and evaluation, management, consequence and refocusing reliability coefficient was calculated as .86, .90, .86 and .83, respectively. Confirmatory factor analysis was conducted to examine to what extend the model was acceptable. Results of the confirmatory factor analysis revealed that the model was acceptable. Adapted instrument was valid and reliable to use.
