Abstract: | The purpose of this study was to examine postprogram exercise motivation and adherence in cancer survivors who participated
in the Group Psychotherapy and Home-Based Physical Exercise (GROUP-HOPE; Courneya, Friedenreich, Sela, Quinney, & Rhodes,
2002) trial. At the completion of the GROUP-HOPE trial, 46 of 51 (90%) participants in the exercise group completed measures
of attribution theory constructs. A5-week follow-up self-report of exercise wasthen completed by 30 (65%) participants. Correlational
analyses indicated that program exercise, perceived success, expected success, and affective reactions were strong predictors
of postprogram exercise. In multivariate stepwise regression analyses, program exercise and perceived successwere the strongest
predictors of postprogram exercise. Additionally, perceived success was more important than objective success in understanding
the attribution process, and it interacted with personal control to influence expected success and negative affect. Finally,
postprogram quality of life and changes in physical fitness were correlates of perceived success. We concluded that attribution
theory may have utility for understanding postprogram exercise motivation and adherence in cancer survivors. |
