title: Proof of Concept of a Mobile Health Short Message Service Text Message Intervention That Promotes Adherence to Oral Anticancer Agent Medications: A Randomized Controlled Trial.
abstract: This multisite, randomized controlled trial assigned 75 adult cancer patients prescribed an oral anticancer agent to either an experimental group that received daily text messages for adherence for 21 days plus usual care or a control group that received usual care.
  
  
  
  Measures were administered at baseline, weekly (Weeks 1-8), and at exit (Week 9). A satisfaction survey was conducted following the intervention. Acceptability, feasibility, and satisfaction were examined. Primary outcomes were adherence and symptoms. Secondary outcomes were depressive symptoms, self-efficacy, cognition, physical function, and social support. Mixed or general linear models were used for the analyses comparing trial groups. Effect sizes (ES) were estimated to gauge clinical significance.
  
  
  
  Regarding acceptability, 57.2% (83 of 145) of eligible patients consented, 88% (n = 37 of 42) receiving text messages read them most or all of the time, and 90% (n = 38) were satisfied. The differences between experimental and control groups' ES were 0.29 for adherence, 0.21 for symptom severity, and 0.21 for symptom interference, and differences were not statistically significant. Furthermore, perceived social support was higher (p = 0.04; ES = 0.54) in the experimental group.
  
  
  
  Proof of concept and preliminary efficacy of a mobile health intervention using text messages to promote adherence for patients prescribed oral anticancer agents were demonstrated. Patients accepted and had high satisfaction with the intervention, and adherence improved after the intervention. Text messages show promise. Additional research is needed prior to use in practice.
