The effect of motivational interviewing on the illness perception in patients after percutaneous coronary intervention

Objective To evaluate the impact of motivational interviewing (MI) on the illness perception in patients after percutaneous coronary intervention (PCI). Methods Totally 160 patients after PCI were randomly divided into two groups. The patients in the control group (n=85) received routine education, while patients in the intervention group (n=75) were received 4 times MI (during hospitalization, before discharge, 1 month after discharge, 3 months after discharge), 20 min for each time. Illness perception was appraised before and after the intervention in both groups. Results The mean scores of illness perception in the intervention group, including symptom perception, disease perception and cause perception, were 5.85±1.75, 3.65±0.66, 2.85±0.30, which were significantly higher than that of the control group after the intervention, 4.84±1.09, 2.92±0.61, 2.48±0.31, the differences were significantly statistical (t=2.248, 3.717, 3.926, all P<0.05). Conclusions MI is much more effective than routine education on the improvement of illness perception in patients after PCI.
