Note. Monthly effects excluded for simplicity. Referent groups for parameters listed in parentheses. Goal Type and Reinforcement Timing were independently effect coded (-0.5, 0.5) and Phase was dummy coded (0 = baseline,1 = intervention). OR = odds ratio, RR = risk ratio, CI = confidence interval. OR for the hurdle model reflects odds of any (vs. no) MVPA, RR for the count model reflects MVPA bout minutes/day on active days. OR, RR, and 95% CI are exponentiated coefficients of conditional estimates. .p < .1, *p < .05, **p < .01, ***p < .001
