Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Validity and Reliability of the Turkish Version of the Cognitive Self-Efficacy Questionnaire (CSEQ)
Time Frame: Baseline and 14-21 days for test-retest assessment
Assessment of the psychometric properties of the Turkish version of the CSEQ in individuals with Parkinson's disease, including internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficient), and construct validity through factor and correlation analyses.
Baseline and 14-21 days for test-retest assessment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Self-Efficacy for Managing Chronic Disease (6-Item Scale)
Time Frame: Baseline
Assessment of perceived self-efficacy in managing chronic disease using the 6-Item Self-Efficacy for Managing Chronic Disease Scale. The scale evaluates individuals' confidence in managing symptoms such as pain, fatigue, emotional distress, and disease-related problems. It consists of 6 items scored on a 10-point Likert scale (1 = not at all confident, 10 = totally confident), with the total score calculated as the mean of all items. Higher scores indicate greater self-efficacy in disease management. The validated Turkish version will be used.
Baseline
Montreal Cognitive Assessment (MoCA-TR)
Time Frame: Baseline
Cognitive function will be assessed using the Turkish version of the Montreal Cognitive Assessment (MoCA-TR). This screening tool evaluates multiple cognitive domains including visuospatial/executive functions, naming, attention, language, abstraction, delayed recall, and orientation. The total score ranges from 0 to 30, with higher scores indicating better cognitive function. The validated Turkish version for Parkinson's disease will be used.
