Research suggested combining modern test theory with classical test theory to achieve comprehensive evaluation of an assessment tool. However, the Norwegian Self-Efficacy for Therapeutic Use of Self questionnaire has not yet been examined by the modern test theory. This study aims to examine psychom...

      ab: Research suggested combining modern test theory with classical test theory to achieve comprehensive evaluation of an assessment tool. However, the Norwegian Self-Efficacy for Therapeutic Use of Self questionnaire has not yet been examined by the modern test theory. This study aims to examine psychometric properties of the Norwegian Self-Efficacy for Therapeutic Use of Self questionnaire by using Rasch analysis. One hundred and eleven occupational therapy students from two universities in Norway completed the questionnaire across four time points. Rasch analysis was used to examine the appropriateness of the rating scales, unidimensionality, person response validity, item/person separation, and the Wright map. The ten-point rating scale did not fully maximise the measurement potentials. Unidimensionality was confirmed except for two items. Person response validity needs further investigation. Excellent person/item separation and Wright map were found. This study supports the psychometric properties of the Norwegian Self-Efficacy for Therapeutic Use of Self questionnaire in assessing self-efficacy in therapeutic encounters. Further research is needed to address the misfit items and the rating scale issue. Rasch analysis showed that the Norwegian Self-Efficacy for Therapeutic Use of Self questionnaire is promising to be used as a reliable and valid tool.
