Peer mentors delivering a physical activity intervention for cancer survivors: effects among mentors.

To further inform implementation efforts of a telephone-based physical activity (PA) intervention for breast cancer survivors, we assessed the PA, fatigue, mood, and quality of life of the peer mentors/coaches who delivered the program. The coaches were volunteers with the American Cancer Society's Reach to Recovery program. The coaches (n = 18) delivered the PA intervention to 76 breast cancer survivors in a randomized controlled trial. Coaches completed assessments of PA (self-report), motivational readiness for PA, and standardized measures of psychosocial variables at the start of coaching and at study exit. At study exit, they also responded to an open-ended question on the benefits that they accrued from the study. We used generalized linear models to analyze the PA data and psychosocial variables. Chi-squared analyses were used for motivational readiness. The written responses to the open-ended question were analyzed to identify themes. Coaches' PA exceeded national recommendations at study entry and exit with no significant changes over time. Sixty-one percent were in the maintenance stage of motivational readiness, and 61% remained in the same stage at study exit. Psychosocial functioning also remained stable over time. Qualitative data revealed that the coaches' gains included helping themselves (with four subthemes) and helping others. Intervention delivery had no unintended negative consequences (PA, motivational readiness, and psychosocial functioning) among coaches. They reported gains that were not reflected in standardized psychosocial assessments. These data support further implementation of peer-delivered PA programs to enhance the reach of interventions.
