The purpose of this study was to explore the original version of Mitchell and Hastings's (1998) Emotional Reaction to Challenging Behavior Scale (ERCBS) and estimate validity and reliability of a revised version containing 29 items. The Emotional Reaction to Challenging Behavior Scale-Korean (ERCBS-K) was studied using 445 in-service physical educators (228 females; 217 males). Data were collected using onsite administration as well as mail survey administration procedures. Confirmatory and exploratory factor analyses results supported a five factor, 28-item scale (ERCBS-K). Acceptable internal consistency coefficients were found for each of the subscales of the ERCBS-K (Cronbach's alpha ranged from 0.71 to 0.87).
