Effects of motivational interview on medication adherence and control level of asthma in adult patients with asthma

Abstract

Objective To explore the effects of the motivational interview on medication adherence and control level of asthma in adult patients with asthma. Methods A total of 100 asthma patients who were hospitalized in the Respiration Department of Putuo People's Hospital in 2016 were selected in the study using convenience sampling. According to the random number table, the participants were divided into the observation group (n=50) and the control group (n=50) . Two cases from the observation group withdrew from the study due to personal reasons, leaving 48 patients in the observation group. Three cases from the control group withdrew from the study (i.e. two for disease changes and one for personal reasons) , leaving 47 cases in the control group. The control group received conventional health education while the observation group received education based on motivational interview. The asthma medication compliance scale (Chinese version) (MARS-A) and asthma control test (ACT) questionnaire were used to evaluate the medication compliance and asthma control level before the intervention and 1, 2 and 3 months after the intervention. Results None of the patients had good medication compliance before the intervention. However, patients in the observation group had significantly better adherence at 1, 2, and 3 months after the intervention compared with the control group (P 0.05) . But after the intervention, the repeated variance analysis showed that there were significant differences in both intervention effect and time effect for asthma control score, and the interaction effects existed between intervention and time (P<0.05) . Conclusions The health education based on motivational interview can effectively improve the medication adherence and the control level of asthma in adult patients with asthma.
