Hispanic breast cancer survivors (BCS) are at high risk for experiencing poor health-related quality of life (HRQoL) after completion of active breast cancer treatment. Therefore, there is a need to develop culturally tailored interventions for Hispanic BCS. To date, there have been limited interventions that have demonstrated that increasing cancer-related knowledge, self-efficacy in communication, and self-management skills can improve HRQoL among Hispanic BCS. These interventions have been delivered in person or by phone, which may be burdensome for Hispanic BCS. To facilitate intervention delivery, we developed My Guide, a Smartphone application aimed at improving HRQoL among Hispanic BCS. The purpose of the current study is to describe the feasibility results of a 4-week pilot trial testing My Guide among Hispanic BCS. Twenty-five women enrolled in the study (75% recruitment rate) and 22 women were retained (91.6% retention rate). Mean time spent using My Guide across the 4 weeks was 9.25 hr, and mean score on the satisfaction survey was 65.91 (range 42-70), in which higher scores reflect greater satisfaction. Participants' scores on the Breast Cancer Knowledge Questionnaire significantly improved from study baseline (M = 9.50, SD = 2.92) to the postintervention assessment (M = 11.14, SD = 2.66), d = 0.59. Participants' HRQoL scores improved over the course of 4 weeks, but these improvements were not statistically significant. Overall, My Guide was feasible and acceptable. Future studies will assess the preliminary efficacy of My Guide in improving HRQoL in a larger, randomized trial of Hispanic BCS.
