Adherence to PA behavior interventions remain challenging in both groups. Further long‐term trials should consider intense motivational support within the first month, more detailed data collection for the control group, adjustments to power calculations and other study designs to minimize non‐adherence and contamination.We examined patterns and predictors of physical activity (PA) adherence and contamination in a one‐year individualized randomized controlled PA behavioral intervention in childhood cancer survivors (CCS). Adherence was 48% in the intervention group, while 17% of controls contaminated group allocation. Clear differences in PA behavior of adherent and non‐adherent participants were seen from week 4. Further long‐term trials should consider intense motivational support within the first month, adjustments to power calculations and other study designs to minimize non‐adherence and contamination.
