Abstract
The objective of this study was to perform an independent validation of the Scales for Outcomes in Parkinson's Disease–Psychosocial questionnaire (SCOPA‐PS) and assessment of the Parkinson's Disease Questionnaire (PDQ‐39), Brazilian version. Patients were evaluated by means of the Unified Parkinson's Disease Rating Scale, Hoehn and Yahr staging (HY), Schwab and England scale, Mini‐Mental State Examination, and Hospital Anxiety and Depression Scale. Health‐related quality of life was evaluated using the MOS‐Short Form 36 (SF‐36), PDQ‐39, and SCOPA‐PS. One hundred forty‐four patients were included (mean age, 62 years; 53.5% males; mean duration of illness, 6.6 years; HY, 1–4). Mean SCOPA‐PS and PDQ‐39 Summary Index (SI) were 39.2 and 40.7, respectively. The internal consistency of SCOPA‐PS (Cronbach's alpha = 0.84; item–total correlation, 0.44–0.73) and PDQ‐39 dimensions (alpha = 0.61–0.85; item–total correlation, 0.46–0.82) were satisfactory. Concerning the stability of the questionnaires, intraclass correlation coefficient (ICC) values were 0.71 for the SCOPA‐PS and 0.86 for the PDQ‐39 SI. ICC for PDQ‐39 dimensions ranged from 0.52 (social support) to 0.80 (stigma). Standard error of measurement (SEM) values for each PDQ‐39 dimension ranged from 0.49 (emotional well‐being) to 17.52 (social support). SEM values for SCOPA‐PS and PDQ‐39 SI were 11.84 and 6.72, respectively. A significant correlation of SCOPA‐PS and PDQ‐39 SI with the SF‐36 physical (−0.42 and −0.52, respectively) and mental components (−0.41) was found. Correlation between SCOPA‐PS and PDQ‐39 SI was 0.73 (all coefficients, P < 0.0001). The SCOPA‐PS and PDQ‐39, Brazilian versions, have satisfactory metric attributes. © 2006 Movement Disorder Society
