Abstract

Various instruments with good psychometric properties have been developed for the assessment of health-related quality of life (HRQoL) in Parkinson's disease, (PD); however, in everyday practice a brief questionnaire is needed for quick screening of patients. We present the process of development and validation of the Greek version of PD questionnaire-8 (PDQ-8(GrV)), which is an 8-item scale derived from a well-known measure for the evaluation of HRQoL in PD, the PD questionnaire (PDQ-39). PDQ-8 (GrV) was applied to 228 nondemented Greek PD patients. Data from PDQ-39 were also collected from these patients for comparisons between the total scores of the two scales. Detailed statistical analysis showed that PD-8(GrV) has psychometric properties analogous to its parent questionnaire.
