“…Furthermore, as measured by Cronbach’s alpha, the internal consistency for the scale in our study (0.93) was in line with those found in previous studies 18–24. Similarly, corrected item-total correlations (Table 4) overlap previous findings 20–23.…”

“…As such, our study found a moderate correlation between PFS-16 and PDQ-39 summary index and with its domains of social support, cognitions, and communication, suggesting an association of these factors with fatigue’s effect on QoL in APD. Other studies have found a moderate or close relationship between PFS-16 and QoL measures,22,24,66,67…”

“…This patient-based, 16-item scale assesses the presence and severity of fatigue in PD patients, captures the physical aspects of fatigue and its impact on activities of daily living, and purposefully excludes fatigue’s mental aspects. In previous studies, it has shown satisfactory internal consistency, stability, and construct validity,18–24 and is recommended by the Movement Disorder Society Task Force 25…”

Purpose: To validate the Parkinson’s Fatigue Scale (PFS-16) in advanced Parkinson Disease (APD) patients using the scale’s Spanish version. Patients and methods: In a clinical study for Levodopa-Carbidopa Intestinal Gel (LCIG), 59 patients were assessed over six months using the PFS-16 and other instruments. The psychometric properties of the PFS-16 were then analyzed. Results: Patients (60.7% men) were aged 68.02±7.43 years. PD duration was 12.57±5.97 years. Median Hoehn and Yahr (HY) stage of patients in “on” was 2 (range: 1–4). There were excellent data quality and acceptability for the PFS-16 as a whole, except for moderate-to-high ceiling effects in its items. Two factors explained 67% of the variance, yet parallel analysis demonstrated the unidimensional nature of the PFS-16, whose internal consistency was satisfactory (Cronbach’s alpha=0.93; item homogeneity coefficient=0.19, and item total-corrected correlations=0.50–0.84). PFS-16 total score showed moderate-to-high correlations with fatigue-specific questions within clinical tools, namely item 20 of the Beck Depression Inventory (r S =0.65) and item 4 of the Non-Motor Symptoms Scale (r S =0.33). Weak-to-moderate correlations were observed between the PFS-16 and measures of anxiety, depression, apathy, and quality of life. There were no significant differences in PFS-16 total scores when grouped by age, sex, time from diagnosis, HY, and CGI-S. After treatment with LCIG, the relative change in PFS-16 total score was −17.6% and the effect size (Cohen’s d ) was 0.92. Moderate correlations between changes in the PFS-16 and several other clinical tools were also found. Conclusion: In APD patients, the PFS-16 showed satisfactory acceptability, internal consistency, construct validity, and responsiveness.

“…The objectives were to develop a valid and reliable measure of fatigue that resulted from the personal experiences of people with PD, that had minimal overlap with other motor and non-motor symptoms of PD, and that was practical for use in the clinic [74]. The scale, which consists of 16 questions, has been validated in Turkish [75], Chinese [76], Greek [77], and Spanish [78]. The Cronbach's α value ranges from 0.930 to 0.974, showing excellent internal consistency, while the ICC varies from 0.50 to 0.93.…”

Introduction. The clinical, social, and economic implications of Parkinson's disease (PD) are significant; disability occurs leading to a low quality of life (QoL). Information on the QoL of patients with PD and studies on the relationship between QoL and motor and cognitive function are necessary for both research and clinical use to make informed decisions in healthcare and rehabilitation. The aim of this study was to determine which scales are most used to assess QoL in patients with PD. Area covered. A literature search was conducted in MEDLINE, Scopus, CINAHL, PsycINFO, and Web of Science. Two authors independently identified eligible studies based on predefined inclusion criteria and extracted the data. Study quality and the risk of bias were assessed using the COSMIN checklist. Expert opinion. 116 suitable studies were included, and 42 different instruments were identified.The most frequently used scales were the 39-items and 8-items Parkinson's Disease Questionnaire (PDQ-39) (PDQ-8). These findings suggest further investigation of existing PD outcome measures would benefit patients, researchers, and clinicians. Validated, universal outcome measures are required to allow comparisons across practice; therefore, we recommend that future researchers use a common set of outcome assessments based on the results of this review.
