Table presents odds ratios (OR) for multinomial logistic regression. Profile 1 = slowly increasing high positive affect profile; Profile 2 = rapidly decreasing medium positive affect profile; Profile 3 = constant medium positive affect profile. Profile 3, Profile 1 and males are the reference categories. The non-significant variable and interactions that were dropped from the final analysis are indicated by ns; *p < 0.05, **p < 0.01, ***p < 0.001.
