- Abstract
- Objective;Autonomic symptoms are commonly observed in patients with Parkinson’s disease (PD) and often limit the activities
of daily living. The Scale for Outcomes in Parkinson’s disease-Autonomic (SCOPA-AUT) was developed to evaluate and
quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in
English, into Korean and to evaluate its reliability and validity for Korean PD patients.
Methods;For the translation, the following processes were performed: forward translation, backward translation, expert review,
pretest of the pre-final version and development of the final Korean version of SCOPA-AUT (K-SCOPA-AUT). In total,
127 patients with PD from 31 movement disorder clinics of university-affiliated hospitals in Korea were enrolled in this study.
All patients were assessed using the K-SCOPA-AUT and other motor, non-motor, and quality of life scores. Test-retest reliability
for the K-SCOPA-AUT was assessed over a time interval of 10−14 days.
Results;The internal consistency and reliability of the K-SCOPA-AUT was 0.727 as measured by the mean Cronbach’s
α-coefficient. The test-retest correlation reliability was 0.859 by the Guttman split-half coefficient. The total K-SCOPA-AUT
score showed a positive correlation with other non-motor symptoms [the Korean version of non-motor symptom scale (KNMSS)],
activities of daily living (Unified Parkinson’s Disease Rating Scale part II) and quality of life [the Korean version of Parkinson’s
Disease Quality of Life 39 (K-PDQ39)].
Conclusion;The K-SCOPA-AUT had good reliability and validity for the assessment of autonomic dysfunction in Korean PD
patients. Autonomic symptom severities were associated with many other motor and non-motor impairments and influenced
quality of life.
