Age and positive affect scores were not significantly associated at baseline ( r = −.098, p = .557), or change from baseline ( r = .285, p = .083), though were marginally significant post-intervention ( r = −.308, p = .060), suggesting older ages were associated with lower positive affect at the end of the study, regardless of intervention type.
