Rasch Analysis of the Norwegian Self-Efficacy for Therapeutic Use of Self Questionnaire

Abstract

Date Presented 04/12/21 We examined the psychometric properties of the Self-Efficacy for Therapeutic Use of Self questionnaire by Rasch analysis. The questionnaire was completed by 111 students across four time points. Unidimensionality was confirmed for all three parts of the questionnaire. The rating scales and person response validity need further investigation; excellent internal consistency and person-item separation was found. The study supports the psychometric properties of the questionnaire. Primary Author and Speaker: Chia-Wei Fan Contributing Authors: Kathy Dahl, Marc Corbiere
