Brief Summary

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.

Conditions

Parkinson Disease; Temperature Sensivity

Outcome Measures

Primary Outcomes (1)

• Heat Sensitivity Scale Total Score

  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.

  Baseline (at the time of questionnaire administration)

Secondary Outcomes (1)

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

  Baseline (at the time of questionnaire completion)

Eligibility Criteria

• Age: 40 Years - 85 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population will consist of individuals with clinically diagnosed Parkinson's disease (Hoehn and Yahr stage 1-3), aged between 40 and 85 years, with adequate cognitive function (MMSE ≥ 24). Participants will be recruited from patients attending the Movement Disorders Outpatient Clinic of the Neurology Department. The study population represents ambulatory individuals with mild to moderate disease severity suitable for comprehensive biopsychosocial assessment.

You may qualify if:

• Clinical diagnosis of Parkinson's disease
• Hoehn and Yahr stage 1-3
• Age between 40 and 85 years
• Mini-Mental State Examination score ≥ 24
• Sufficient cognitive and communication ability to complete the assessments
• Attendance at the Movement Disorders Outpatient Clinic of the Neurology Department
• Willingness to participate and provide written informed consent

You may not qualify if:

• Presence of a major psychiatric disorder, such as major depressive disorder or a psychotic disorder
• Diagnosis of advanced dementia
• Presence of an uncontrolled systemic chronic disease, such as uncontrolled diabetes mellitus or hypertension
• Presence of a severe cardiovascular or respiratory condition
• Presence of an additional orthopedic or neurological condition that may affect assessment performance
• Severe visual or hearing impairment that may interfere with the assessments
• Inability to cooperate adequately during the assessments
