The International Physical Activity Questionnaires (IPAQ) (Suhardjono et al., 2019)	Physical	5 Job-related; Transportation; Housework, house maintenance, caring for the family; Recreation, sport, leisure time; Time spent sitting.	27	The overall score is calculated using all responses. Patients are categorized into 1 of 3 categories based on physical activity: low/inactive, moderate, or high. Self-reported
Chalder Fatigue Scale (CFQ 11) (Picariello et al., 2018, Picariello et al., 2021)	Physical, Psychological	2 Physical fatigue; Psychological fatigue	11	The questionnaire measures fatigue severity through 11 items scored against a 4-point Likert-type response scale.

Scores exceeding 20 indicate moderately severe or worse psychopathology. Scores between 10 and 20 are associated with significant functional impairment but less severe symptoms Scores below 10 are associated with subclinical populations. Self-administered
The International Physical Activity Questionnaires (IPAQ-SF) (Picariello et al., 2018, Picariello et al., 2021)	Physical	1 General Physical activity	7	Divided into 3 categories based on the patient's physical activity: Low, moderate, and high activity.
