MethodsaaWe enrolled 129 PD patients with movement disorders from 31 clinics in South Korea. The original version of theSCOPA-Cog was translated into Korean using the translation-retranslation method. The test–retest method with an intraclass correlationcoefficient (ICC) and Cronbach’s alpha coefficient were used to assess reliability. Spearman’s rank correlation analysis withthe Montreal Cognitive Assessment-Korean version (MOCA-K) and the Korean Mini-Mental State Examination (K-MMSE) wereused to assess concurrent validity.
