| Abstract: | Turkish-Sign-Language (TSL) is a natural visuospatial language that the Deaf and hard of hearing use to communicate both with each other and with hearing people. It is important to determine the self-efficacy of individuals learning TSL in order to enhance their effective use of the TSL when their learning process. In this study, we aimed to develop a scale that measures TSL self-efficacy for TSL learners and provide valid and reliable results with different test theories. The study was designed in a quantitative research design, and the participants consisted of 430 university students who were identified through a purposive sampling technique. Automated item selection procedure in the context of Mokken Homogeneity Model-one of the nonparametric item response theory models, and principal axis factoring, convergent and discriminant validity in the context of classical test theory were investigated to present evidence for construct validity. According to the analysis, a measurement tool consisting of 22 items and a three-factor structure was reached. The reliability coefficients of the scores were investigated via Cronbach's Alpha ([alpha]), Guttman's lambda 2 ([lambda), latent class reliability coefficient (LCRC), composite reliability coefficients (CR), and McDonald's omega (?). The reliability values obtained from these coefficients indicated that the scores obtained from the scale were reliable. As a result, the TSL-Self-Efficacy Scale for TSL learners, which provided valid and reliable results, was successfully developed. |
