한국판 응시불안평가척도(K-GARS)의 타당화 연구

초록

This study investigated the psychometric properties of the Korean version of Gaze Anxiety Rating Scale (K-GARS) with factor analysis and polytomous item response theory(polytomous IRT). A total 333 university student were asked to respond to K-GARS and questionnaires to measure social anxiety tendency. Exploratory factor analysis revealed four factor structures in gaze avoidance dimension and gaze anxiety dimension, consisting of three factor structure with a high internal consistency and convergent validity. People mainly reported gaze avoidance in the public speaking or evaluative situation. They felt gaze anxiety when they were engaged in public attention. Polytomous IRT revealed that all items had appropriate discrimination to measure the trait of gaze avoidance and gaze anxiety accurately. Therefore, no item was eliminated from the original GARS. This suggested that Korean version of GARS could be extended from the restricted study field of gaze avoidance and gaze anxiety where empirical data are mostly studied. It could also be practically used in clinical context with a high reliability.
