Adequately assessing not only the quantity but also the quality of practice is important for achieving high-level performance among sports athletes. We aimed to develop the Self-Regulation of Learning in Sports Scale based on the Self-Regulation of Learning Self-Report Scale (SRL-SRS; Toering et al., 2012) and to verify its predictive validity in measuring the quality of practice. Five hundred and eight university students belonging to physical activity clubs completed the questionnaire. Exploratory factor analysis showed five subscales with a factor structure similar to the original questionnaire (SRL-SRS): planning, self-monitoring, effort, self-efficacy, and evaluation/reflection. Each subscale and five-factor model was demonstrated to be reliable and valid on reliability and confirmatory factor analyses, respectively. Additionally, we examined the relationship between each subscale score and the actual competition level of students. As a result, international-, national-, and area-level students showed significantly higher scores than prefecture-level students on some subscales, which supports the predictive validity of this scale. Thus, the Self-Regulation of Learning in Sports Scale, incorporating five subscales (37 items), was developed for the measurement of the quality of practice.
