We tested whether an online intervention combined with a patient feedback report improved physicians' use of motivational interviewing (MI) techniques when discussing weight with overweight and obese adolescents.
Methods
We randomized 46 pediatricians and family physicians and audio recorded 527 patient encounters. Half of the physicians received an individually tailored, online intervention. Then, all physicians received a summary report detailing patient's weight-related behaviors. We coded MI techniques and used multilevel linear mixed-effects models to examine arm differences. We assessed patients' motivation to change and perceived empathy after encounter.
Results
We found arm differences in the Intervention Phase and the Summary Report Phase: Empathy (p < .001), MI Spirit (p < .001), open questions (p = .02), and MI consistent behaviors (p = .04). Across all three phases (Baseline, Intervention, and Summary Report), when physicians had higher Empathy scores, patients were more motivated to change diet (p = .03) and physical activity (p = .03). In addition, patients rated physicians as more empathic when physicians used more MI consistent techniques (p = .02).
Conclusions
An individually tailored, online intervention coupled with a Summary Report improved physicians' use of MI, which improved the patient experience.
