The Emotional Reactions to Challenging Behavior Scale-Korean (ERCBS-K): modification and validation.

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).
