"Turkish Validity and Reliability of the Heat Sensitivity Scale for Individuals With Parkinson's Disease"

The aim of this study is to examine the validity and reliability of the Turkish version of the Heat Sensitivity Scale in individuals with Parkinson's disease. This cross-sectional methodological study will evaluate the psychometric properties of the scale, including internal consistency, test-retest reliability, and construct validity, in order to provide a valid and reliable tool for assessing temperature sensitivity in Turkish-speaking individuals with Parkinson's disease.

Treatment and study plan

Primary outcomes

Heat Sensitivity Scale Total Score

Time frame: Baseline (at the time of questionnaire administration)

Heat sensitivity will be assessed using the Turkish version of the Heat Sensitivity Scale in individuals with Parkinson's disease. The scale evaluates symptoms related to heat sensitivity and their impact on daily life. The total score ranges from 29 to 116, with higher scores indicating greater heat sensitivity-related problems and therefore a worse outcome. Psychometric properties, including internal consistency, test-retest reliability, and construct validity, will be analyzed.

Secondary outcomes

Parkinson's Disease Questionnaire-39 (PDQ-39) Total and Subscale Scores

Time frame: Baseline (at the time of questionnaire completion)

Quality of life will be assessed using the Parkinson's Disease Questionnaire-39 (PDQ-39), a validated self-report measure specific to Parkinson's disease. The questionnaire consists of 39 items across 8 domains, including mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort. Scores can be transformed to a 0-100 scale, with higher scores indicating worse quality of life. PDQ-39 scores will be used to evaluate the construct validity of the Turkish version of the Temperature Sensitivity Scale.
