Summary
Parkinson's Disease (PD) is a progressive neurodegenerative disorder characterized by the involvement of dopaminergic pathways in the basal ganglia. Motor and non-motor symptoms are frequently observed in PD. These symptoms may negatively affect the quality of life of individuals with PD. Therefore, it is recommended to evaluate the quality of life of individuals with PD and plan appropriate treatments. The "Parkinson's Disease Quality of Life 7 (PDQoL7)" questionnaire is a patient-reported quality of life assessment questionnaire developed specifically for individuals with PD. The questionnaire, which consists of 7 questions in total, evaluates the degree of difficulty the patient has in performing various activities. The aim of this study was to adapt the PDQoL7 questionnaire into Turkish and to establish its validity and reliability.
Detailed description
Parkinson's Disease (PD) is a progressive neurodegenerative disorder characterized by the involvement of dopaminergic pathways in the basal ganglia. Motor and non-motor symptoms are frequently observed in PD. These symptoms may negatively affect the quality of life of individuals with PD. Therefore, it is recommended to evaluate the quality of life of individuals with PD and plan appropriate treatments. The "Parkinson's Disease Quality of Life 7 (PDQoL7)" questionnaire is a patient-reported quality of life assessment questionnaire developed specifically for individuals with PD. The questionnaire, which consists of 7 questions in total, evaluates the degree of difficulty the patient has in performing various activities. The aim of this study was to adapt the PDQoL7 questionnaire into Turkish and to establish its validity and reliability. The study data will be collected in collaboration with Gazi University, Faculty of Health Sciences, Department of Physiotherapy and Rehabilitation and Niğde Ömer Halisdemir University and will be conducted with individuals diagnosed with PD who applied to the Neurology Outpatient Clinic of Niğde Ömer Halisdemir University Training and Research Hospital. Necessary permissions were obtained from all institutions and the people who developed the questionnaire. After the purpose and method of the study were explained to the participants in detail, individuals who voluntarily agreed to participate in the study will be included in the study. The serial approach method will be used when translating the original questionnaire into Turkish. Since at least 5-10 times the number of items in the questionnaire should be included in order to perform factor analysis, a pretest of the questionnaire will be applied to individuals with PD with at least 35-70 participants. "Parkinson's Disease Questionnaire-39" and "Short Form-36" questionnaires will be administered to the patients to assess concurrent validity. To determine test-retest reliability, the PDQoL7 questionnaire will be administered to the same patients 2 weeks later, and correlation analysis and test-retest reliability will be calculated. Cronbach's Alpha Reliability coefficient will be applied to determine the internal consistency of the questionnaire. The construct validity of PDQoL7 will be analyzed by confirmatory factor analysis.

|---|---|---|
| OTHER | Validity, Reliability and Adaptation | The Hoehn \& Yahr Scale (HDS) and the Unified Parkinson's Disease Rating Scale (UPDRS) will be used for the clinical evaluation and disease staging of the individuals included in the study. In addition to the PDQoL-7 questionnaire, the 'Short Form-36' and 'Parkinson's Disease Questionnaire-39' questionnaires will be administered to patients to assess concurrent validity. Since at least 5-10 times the number of items in the questionnaire (7 items) must include at least 5-10 times the number of participants in order to perform factor analysis, a pretest of the questionnaire will be applied to individuals with PD with at least 35-70 participants. To determine the test-retest reliability, the PDQoL7 questionnaire will be administered again to the same patients after 2 weeks. |
