Purpose: To describe the theoretical, evidence-based and consumer-informed development of a smartphone self-management program aiming to support adherence to oral chemotherapy in adolescents and adults diagnosed with cancer.
Methods: The design of the program followed two frameworks for the development and evaluation of mHealth interventions and was conducted in three steps: 1) conceptualization, which involved an extensive literature review and a scoping review that led to the identification of the behavioral change strategies in the program; 2) definition of features and structure, based on a formative study with end-users to explore their preferences about the structure and elements of the program; and 3) selection of program delivery technology, whereby available technology platforms were examined and the most suitable tool to deliver the program was selected.
Results: Three main reasons for oral chemotherapy non-adherence were identified: forgetfulness, side-effects and poor knowledge about oral chemotherapy. Key behavior change strategies were also identified, namely, medication intake reminders and information about oral chemotherapy and managing side-effects. Based upon end-user feedback the method of delivery of these behavioral strategies that was deemed most appropriate was conventional text messages. The reminders were standard, short, text-only messages sent when each oral chemotherapy dose was due, one way (no need to reply) and addressed the end-users using their first name. Delivery of information about oral chemotherapy and side-effects was tailored to each individual’s preferred frequency.
Conclusion: The careful design process described in this paper may serve to inform the development of future mobile phone-based medication adherence-enhancing interventions for people with cancer. A trial to explore end-users acceptability of and satisfaction with the intervention is currently underway.
