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

July 14, 2026 updated by: Nuray Alaca, Acibadem University

Cross-Cultural Adaptation and Psychometric Evaluation of the Turkish Version of the Temperature Sensitivity Scale in Individuals With Parkinson's Disease

The aim of this study is to examine the validity and reliability of the Turkish version of the Temperature 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.

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.

Description

Inclusion Criteria:

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

Exclusion Criteria:

  • Presence of psychiatric disorders (e.g., major depression or psychotic disorders) Diagnosis of advanced dementia Presence of uncontrolled systemic chronic diseases (e.g., diabetes mellitus or hypertension) Presence of severe cardiovascular or respiratory conditions Presence of additional orthopedic or neurological conditions that may affect test performance Severe visual or hearing impairments that could interfere with assessments Inability to cooperate adequately with the physiotherapist during assessments

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Temperature Sensitivity Scale Total Score
Time Frame: Baseline (at the time of questionnaire administration)
Temperature sensitivity will be assessed using the Turkish version of the Temperature Sensitivity Scale in individuals with Parkinson's disease. The scale is designed to evaluate temperature sensitivity-related symptoms and their impact on daily life. Psychometric properties including internal consistency, test-retest reliability, and construct validity will be analyzed. Higher scores indicate greater temperature sensitivity-related problems.
Baseline (at the time of questionnaire administration)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
