The Impact of Clinical and Cognitive Variables on Social Functioning in Parkinson's Disease: Patient versus Examiner Estimates

Table 3

Results of multiple regression analyses of clinical variables as predictors of social functioning in patients with PD. Values presented are the standardized coefficient Beta (𝛽) and 𝑃-values for SASS-E, SASS-P, and EQ.
