Turkish version of Parkinson Fatigue Scale: Validity and reliability study of binary scoring method

Area of Science:

• Neurology
• Psychometrics

Background:

• Fatigue is a common and debilitating symptom in Parkinson's disease (PD).
• Accurate assessment of fatigue is crucial for managing PD patients.
• Existing fatigue scales may require cultural adaptation for diverse populations.

Purpose of the Study:

• To translate and cross-culturally adapt the Parkinson Fatigue Scale (PFS) into Turkish.
• To evaluate the reliability and validity of the Turkish version of the PFS for PD patients.

Main Methods:

• The Parkinson Fatigue Scale (PFS) was translated and culturally adapted into Turkish.
• 138 Parkinson's disease patients participated in the reliability and validity testing.
• Data quality, scaling assumptions, internal consistency, and test-retest reliability were assessed using the binary scoring method.

Main Results:

• The Turkish PFS demonstrated excellent data quality and acceptable scaling assumptions.
• High internal consistency (Cronbach's alpha 0.955) and adequate test-retest reliability (correlation coefficients 0.650-0.875) were observed.
• The scale showed significant correlations with various clinical rating scales, indicating good construct validity.

Conclusions:

• The Turkish version of the Parkinson Fatigue Scale (PFS) is a reliable and valid instrument.
• This adapted scale can be effectively used to assess fatigue in Turkish-speaking Parkinson's disease patients.
