Effects of Motivational Interviewing on Treatment Adherence among Patients with Chronic Obstructive Pulmonary Disease: a Randomized Controlled Clinical Trial.

BACKGROUND

Treatment non-adherence is a leading cause of rehospitalization among patients with chronic obstructive pulmonary disease. Motivational interviewing is a client-centered participatory counseling strategy which enhances motivation for change. The aim of this study was to examine the effects of motivational interviewing on treatment adherence among patients with chronic obstructive pulmonary disease.

MATERIALS AND METHODS

This randomized controlled clinical trial was done on 54 hospitalized patients using a two-group repeated measures design. Patients in the intervention group (n=27) received motivational interviewing and lifestyle-related educations, while their counterparts in the comparison group (n=27) solely received lifestyle-related educations. Treatment adherence was measured before, one month, and two months after the intervention.

RESULTS

At baseline, there was no significant difference between the groups regarding treatment adherence (P>0.05); however, one and two months after the intervention, between-group differences regarding treatment adherence were statistically significant (P<0.05).

CONCLUSION

Motivational interviewing promotes treatment adherence among patients with chronic obstructive pulmonary disease.
