    Objectives: To examine predictors of physical activity (PA) 6 months after a randomized controlled trial. Methods: Breast cancer survivors (N=377) completed assessments at baseline, postintervention, and 6 months after the intervention. Data were collected on demographic, medical, psychosocial, motivational, and behavioral variables at baseline, postintervention, and 6 months. Results: Survivors meeting PA guidelines at baseline (OR=5.54, 95% CI=2.99-9.82, P<0.001) and postintervention (OR = 2.92, 95% CI=1.63-5.23, P<0.001) had a greater likelihood of meeting PA guidelines at 6 months follow-up. Conclusions: Interventions promoting PA maintenance should focus on optimizing PA behavior, psychosocial functioning, and motivation.
