무용수 신체적 자기효능감 척도의 개념 및 타당성 검증

Abstract

This study was conducted to verify the concept of dancers’ physical self-efficacy and the validity of the physical self-efficacy scale. For this purpose, dancers from all over the country were set as a population, and then 619 sets of data were used in the study by using convenience sampling for dancers living in Seoul, Gyeonggi, Daejeon, Jeonju, Daegu, Busan, and Gwangju. Data analysis evaluated the validity of the concept of physical self-efficacy through inductive categorization using a group of experts, and the suitability of the scale was evaluated through analysis of the appropriateness of response categories, item suitability, and difficulty using Winstep 5.2.1.0. For this purpose, the following conclusions were drawn from the procedure. First, dancers’ physical self-efficacy was extracted as sub-factors such as physical competence, physical confidence, physical strength, and physical attractiveness. Second, the response category of the dancer physical self-efficacy scale was appropriate as a 3-point response category, and 6 out of 18 items were not appropriate. The difficulty of the items was very biased.
