title: Negative affect and barriers to exercise among early stage breast cancer patients.
abstract: OBJECTIVE
  To assess the relative frequency of and barriers to exercise among women with breast cancer while controlling for cancer-relevant and demographic factors.
  
  
  METHODS
  The present study employed concurrent samples, correlational research design.
  
  
  METHODS
  Exercise frequency and its association with negative affect and barriers to exercise, independent of cancer treatment, among women (N=176) with Stage I or II breast cancer who were 3, 6, and 12 months postsurgery.
  
  
  RESULTS
  After accounting for cancer-relevant and control variables, degree of negative affect and frequency of perceived barriers were significantly inversely associated with exercise.
  
  
  CONCLUSIONS
  These findings suggest that attention to both emotional factors and psychosocial barriers to exercise may be warranted to further understand exercise among women with early stage breast cancer.
