The primary aim of the study will be to examine Social Cognitive Theory (SCT) correlates, of physical activity (PA) participation and health-related quality of life (HRQoL) in Parkinson's disease participants.
The body of evidence in the physical therapy and rehabilitation literature supports that physical activity is associated with improvements in quality of life for Parkinson's Disease (PD) patients. However, few studies have examined the underlying variables that may account for this relationship in PD patients. Researchers have examined stages of readiness to exercise in PD patients and barriers to exercise and found a strong association between self-efficacy and exercise in PD patients, rather than disability .
Researchers suggest that social cognitive theory (SCT) constructs are important correlates of physical activity for PD patients and should be targeted in interventions. A more comprehensive study of SCT correlates - Self-Efficacy (SE), Outcome Expectations (OE), and Self-Regulation (SR) should provide a better understanding of the factors that contribute to physical activity participation and the physical activity / health-related quality of life relationship in PD patients.

The investigators are using a cross-sectional experimental design of 404 geographically diverse Parkinson's participants. Physiologic (Hoehn \& Yahr) and psychological (surveys and single-item measures) measures will be collected via web-based surveys in Qualtrics accessed through a link.
Sample Using (Fritz \& MacKinnon, 2007) article on the required sample size necessary to detect mediated effects, using the empirical estimates in Table 3 for the Baron and Kenny test with ť = .59, α = .59 and β = .14, the desired sample size needed for a power of .8 would be 404. In this population, the investigators expect that some PD participants may start the survey and be unable to finish. For this reason, the investigators would like to oversample by 25% with a target of 505 participants.
Exclusion Criteria:
Patients with idiopathic parkinson's disease
Health-Related Quality of Life (HRQoL) correlation to self-reported physical activity (PA)
multiple linear regression analysis will be used to determine if higher HRQoL is significantly related to self-reported physical activity in PD patients.
Time frame: participant's respond to survey questions only 1 time
Self-efficacy (SE), Outcomes Expectations (OE), and Self-Regulation (SR) correlation to self-reported HRQoL
multiple linear regression analysis will be used to determine if higher levels of SE, OE, and SR are significantly related to self-reported HRQoL.
Time frame: Outcomes as measured at a single baseline assessment
Social Cognitive Theory (SCT) constructs as mediators between self-reported PA and HRQoL
hierarchical linear regression model will be used to examine the SCT constructs as potential mediators between self-reported PA and HRQoL in PD patients. Also, any variables determined to have significant impact in the multiple regression models will be controlled for in the HLM, allowing us to investigate the effects of certain variables while controlling for the effects of others.
Time frame: Outcomes as measured at a single baseline assessment
SCT constructs correlation to self-reported PA
multiple linear regression analysis will then be used to examine the relationship between the social cognitive theory constructs and self-reported physical activity in PD patients.
