Final model (including age, IPAQ, NMSQ, MDS-UPDRS, NMSQ × IPAQ, MDS-UPDRS × IPAQ)	88	0.52	F_(6,81) = 16.98, p < 0.001	p = 0.03 NMSQ × IPAQ: p = 0.02, MDS-UPDRS × IPAQ: p = 0.01	Ns

PAM, Patient Activation Measure; IPAQ, International Physical Activity Questionnaire; NMSQ, Non-Motor Symptoms Questionnaire; MDS-UPDRS, Unified Parkinson’s disease rating scale
Disease severity was assessed using NMSQ, LEDD, and MDS-UPDRS, and health behaviors were measured using IPAQ total score and PAM score
