Habitual Hypertension Medication Adherence in Arizona

This research will implement a novel habit formation intervention among people living with hypertension and an indication of medication non-adherence to help maintain high anti-hypertensive (AH) medication adherence by leveraging the power of routines and unconsciously triggered habitual behaviors. The investigators will test whether high AH medication adherence can be maintained using contextually-cued medication adherence habits that mitigate the negative effects of declining motivation, forgetfulness, and the cognitive burden of performing repeated daily behaviors. The use of mHealth tools will help to make this a scalable and sustainable intervention approach for addressing an important healthcare issue in Arizona.
