Adolescents and young adults (AYA) survivors of childhood cancer receive inadequate surveillance for treatment-related late effects. This study evaluates the acceptability and feasibility of a mobile phone messaging intervention targeting behavior changes related to receiving survivorship care among AYA survivors.

Content from an existing text-messaging survivorship education intervention will be adapted to a novel text-messaging platform, Chorus. Ten AYA survivors will be recruited to participate in the expanded 12-week text messaging intervention. In-depth interviews will be conducted with each participant during the study, and a focus group with all participants will be conducted at the end of the study. Qualitative analysis will determine areas for improvement in the text messaging intervention in order to ensure acceptability and feasibility in AYA survivors. The text messaging intervention on Chorus will be adapted to better suit the needs of AYA survivors based on the results of the qualitative analysis. Mobile phone interventions offer a cost-effective, age-appropriate approach to AYA survivorship care education. If effective, the text-messaging intervention will be evaluated in a randomized, controlled pilot trial to improve rates of survivorship care and clinical outcomes for AYA survivors.


Aim 1: To adapt and enhance an existing text messaging intervention to an expanded two-way multi-media mobile phone messaging platform (Chorus) that will improve knowledge regarding the risk of late effects among AYA survivors, intent to seek recommended survivorship care, and completion of standard survivorship care goals. a. both two-way text messaging to improve Children?s Oncology Group (COG) survivorship guideline adherence b. web-based educational content for survivors of key survivorship messages regarding risk for late effects and need for ongoing survivorship care c. Monthly peer navigation phone calls to address barriers and promote retention d. utilization of pre and post-test questionnaires for participants to access and complete within the Chorus platform Aim 2: To test the acceptability and feasibility of the expanded mobile phone intervention content to improve messaging and strategies for survivorship care using qualitative methodologies and applying the Technology Acceptance Model (TAM) within a sample of AYA survivors. a. perceived usefulness of the text messaging system b. perceived ease of use of the text messaging system c. effect of the text messaging system on health-related behavior intent
