Then, they were randomly divided into three groups: teach-back (Group 1), motivational interviewing (Group 2), and control (Group 3). Three teach-back sessions were held for the teach-back group, five sessions of motivational interviewing for the motivational interviewing group, and the routine care was provided for the control group. In addition, data were collected by the demographic form and scale of Adherence to Systemic Hypertension Treatment, which were completed by participants of all three groups at baseline and also two months from the intervention.
