Demographics + disease severity + health behaviors + interactions	85	0.5	F_(13,71) = 7.36, p < 0.001	p < 0.001	p = 0.03
Final model (including MDS-UPDRS, PAM and IPAQ)	87	0.51	F_(3,83) = 31.23, p < 0.001	p < 0.001	P = 0.02

PAM, Patient Activation Measure; IPAQ, International Physical Activity Questionnaire; MDS-UPDRS, Movement Disorders Society 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
