| Demographics + disease severity | 88 | 0.49 | F(5,82) = 17.44, p < 0.001 | – | – |
| Demographics + disease severity + health behaviors | 88 | 0.49 | F(7,80) = 12.67, p < 0.001 | NS | Ns |
| Demographics + health behaviors + disease severity + interactions | 88 | 0.53 | F(13,74) = 8.52, p < 0.001 |

| 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
