Notes: Standardized coefficients presented; ns vary depending on reported activity participation.
ΔR2 represents the amount of variance in activity-related affect explained by individual differences in extraversion or conscientiousness. This analysis includes all covariates: gender, race, age, education, work status, marital status, depressive symptoms, functional limitations, type of day, trait positive affect and trait negative affect, and time spent in activity (in minutes).
Total R2 represents the total amount of variance in activity-related affect explained by the entire model.
*p < .05. **p < .01. ***p < .001. Bonferroni correction applied.
