We assessed the modified scale, termed the Motor Learning-Specific Inner Speech Scale (MLISS), focusing on its factor structure, internal consistency, and content validity among young adults in Study 1. A total of 325 university students (145 females) participated, completing the MLISS, which comprises 16 items across four dimensions of inner speech: self-criticism, self-reinforcement, self-management, and social assessment. In Study 2, 149 university students (58 females) completed the MLISS and executed three basketball skills: shooting, passing, and dribbling. Data analysis employed confirmatory factor analyses and structural equation modeling, which confirmed the proposed scale structure. Notably, the self-reinforcement and self-management dimensions of the MLISS showed significant correlations with basketball performance, affirming the measure's construct validity. These findings indicate that the MLISS is a valid tool for assessing inner speech frequency in motor learning, marking the first extension of an existing inner speech measure into this domain.</p> https://journals.kmanpub.com/index.php/Health-Nexus/article/download/4310/7626
