BACKGROUND: Lifestyle can play an important role in controlling type II diabetes (T2D), and a
high‑risk lifestyle can exacerbate its effects. The aim of this study was to compare the effectiveness
of motivational interviewing with self‑development education on T2D patients’ lifestyle.
MATERIALS AND METHODS: This was a quasi‑experimental study in 2017–2018. The design was
pretest–posttest with an active comparison group. The population of this study was T2D patients of
Firouzgar and Imam Reza Hospitals in Tehran. Using targeted sampling, 80 patients were selected and
randomly assigned into experimental and comparison groups. The instrument was a tool for assessing
lifestyle determinants in T2D patients (determinants of lifestyle behavior questionnaire) based on the
theory of planned behavior. Intervention program was initially performed, and motivational interviewing
was conducted on Firouzgar Hospital’s patients for 10 sessions while self‑development education
was conducted on Imam Reza Hospital’s patients for 10 sessions (active comparison group). To
analyze the data, independent t‑test and Chi‑square test were used.
RESULTS: The results showed that the patients who received motivational interviewing had significant
improvement in their lifestyles with a 95% confidence level at P = 0.042, compared to the patients
who had been trained with self‑development education.
CONCLUSION: Motivational interviewing improves the lifestyle of T2D patients compared to
self‑development education. It is recommended that motivational interviewing be used to help the
rehabilitation of these patients. This method helps patients control their blood sugar while improving
their lifestyle.
