Self-efficacy to overcome exercise barriers in individuals with cancer-related lymphedema.

Although cancer survivors are recommended to exercise, they may lack confidence (self-efficacy) to be active. This research aimed to measure exercise barriers and related selfefficacy in individuals with cancer-related lymphedema as well as examine relationships between self-efficacy and participant characteristics. A cross-sectional survey was undertaken in individuals with cancer-related lymphedema using a validated 14-item Likert scale assessing self-efficacy to overcome general and lymphedema-specific exercise barriers (0%=not at all confident, 100%=extremely confident). Demographic, medical and lymphedema data were also collected. Of 109 participants (52% response), 79% (n=86) had breast cancer-related lymphedema. Participants were found to be moderately confident to exercise when facing general (48% [95% CI: 44, 52]) and lymphedema- specific exercise barriers (51% [95% CI: 47, 55]). Participants who were female, sedentary (p<0.05), had lymphedema for ≥2 years, and reported greater symptom burden (p<0.05) recorded lower general exercise barriers selfefficacy. Lower lymphedema-specific exercise barriers self-efficacy was reported by individuals who were sedentary, had cancers other than breast, and higher symptom burden. These findings suggest general and lymphedema- specific barriers challenge exercise confidence in those with cancer-related lymphedema, and strategies tailored to improve confidence in overcoming exercise barriers are warranted. Supporting individuals to be sufficiently active during and following cancer treatment should consider behavior change strategies tailored to the unique needs faced by individuals with lymphedema.
