Adaptation and Validation of Self-regulating Capacity in Vocabulary Learning Scale

This paper reports on an adaptation and validation study of Self-regulating Capacity in Vocabulary Learning Scale (Tseng et al. 2006) in a Japanese EFL setting. The piloting phase revealed that factor structures were different from those in the original study. The main study, including a self-reported measure of procrastination to explore the convergent evidence of the construct validity, suggests that the scale can be a valid measure of self-regulation capacity in vocabulary learning in a Japanese EFL environment. These findings provide implications for future studies that utilize the same type of research paradigm
