Abstract
Background Short term exercise interventions have been shown to be beneficial for breast cancer survivors soon after treatments but longer term adherence is needed.
Purpose To examine the effects of a supervised exercise program on motivational variables in breast cancer survivors using Self-Determination Theory (SDT).
Method Sixty breast cancer survivors were randomized in a cross-over design to either an immediate exercise group
(IEG; n=30) that exercised from baseline to week 12 or a delayed exercise group (DEG; n=30) that exercised from week 12 to 24. SDT variables were assessed at baseline, 6,
12, 18 and 24 weeks using the Behavioral Regulation for
Exercise Questionniare-2 and the Basic Psychological
Needs Satisfaction Scale.
Results Fifty-eight participants completed the follow-up assessments and achieved a 61.3% adherence rate. Analyses of variance revealed significant time by group interactions for almost all psychological needs and motivations that favored the exercise intervention time periods. For example,
