This 10-week, 2-group, prospective randomized controlled trial will enroll 75 patients (50 in the intervention group and 25 in the control group), from 2 cancer centers, to test the feasibility and efficacy of a tailored intervention using text messages delivered to patient's cell phones to promote oral agent adherence. As these patients are newly prescribed an oral agent, they will be randomly assigned to either the intervention or the control group. At baseline (week 1), we will assess age, sex, race, cancer type and stage, self-efficacy, comorbid conditions and their SCM, and symptoms. For 21 days (week 2-4) the intervention group will receive a tailored text message for oral agent adherence plus usual care and the control group will receive only usual care. Each week (week 2-9) and at exit (week 10) an assessment of oral agent adherence and symptoms will occur. Satisfaction with the intervention will also be evaluated during the exit interview.
