Abbreviations: CI, confidence interval; DV, dependent variable; EMA, ecological momentary assessment; MVPA, moderate to vigorous physical activity; z-BMI, body mass index z-score.

Note: Between = grand-mean centred variable; within = person-mean centred variable. MVPA and activity counts were assessed within 60 minutes before EMA ratings. Gender was coded such that girls were the reference category. Bolded values indicate significant effects at p <.05.
