Primary Outcome Measures:
- Feasibility and acceptability of using a smartphone medication reminder application to promote adherence to oral medications by AYA with cancer. [ Time Frame: ongoing study weeks 5-12 ] [ Designated as safety issue: No ]
Behavioral: Smart phone medication reminder application
The study intervention will consist of reminders delivered via a smartphone medication reminder application at the time a dose of medication is due. The application to be used is Dosecast (copyright 2011, Montuno Software, LLC) which is publicly available for purchase through the App Store. Participant compensation for study participation will take into account the cost to participants (less than $5) of purchasing the application and participants will receive instruction from the study Clinical Research Associate (CRA) in programming it to deliver audio and visual reminders when a dose of a scheduled oral medication is due and in entering a response to reminders received (medication taken, skipped, or re-reminder requested at a specific time interval). Participants will use the smartphone medication reminder application over an 8 week period for all scheduled oral medications to be taken while outpatient.
Non-adherence to oral medications is a prevalent problem in adolescents and young adults (AYA) with cancer that may impact both survival and quality of life while on treatment. The purpose of this study is to explore use of a smartphone medication reminder application to promote adherence to oral medications by AYA with cancer. The study's primary aim is to explore the feasibility and acceptability of using a smartphone medication reminder application to promote adherence to oral medications by AYA with cancer as well as to characterize application use. Secondary aims include: 1) to obtain initial estimates of intervention effect- measured by pre-intervention to post-intervention differences in perceived behavioral control for adherence, intention to adhere, and adherence behavior - to inform design of a future trial powered to detect a clinically significant effect of smartphone medication reminder application use on adherence to oral medications; and 2) to examine the relationships among perceived behavioral control for adherence, intention to adhere, and adherence behavior. A pre-post single group design will be used. Data will be collected weekly for 4 weeks before introduction of the intervention and for 8 weeks following introduction of the intervention. Analytic approaches will include descriptive statistics and GEE modeling.
