How does physician advice influence patient behavior? Evidence for a priming effect.

Area of Science:

• Health behavior research
• Preventive medicine
• Health psychology

Background:

• Physician advice is a key component of preventive care.
• Patient engagement with health information can be variable.
• Behavioral change interventions aim to modify health-related behaviors.

Purpose of the Study:

• To investigate the "priming effect" of physician advice on patient engagement with subsequent health behavior interventions.
• To determine if physician counseling enhances patient response to educational materials for smoking cessation, dietary changes, and physical activity.

Main Methods:

• A randomized controlled trial was conducted across four community-based family medicine clinics.
• 915 adult patients received printed educational materials on smoking cessation, reduced fat intake, and increased physical activity.
• Outcomes measured included recall and use of materials, and self-reported changes in smoking, diet, and physical activity.

Main Results:

• Patients receiving prior physician advice were more likely to recall, share, and personalize the educational materials.
• Significant improvements were observed in attempts to quit smoking (OR=1.54), successful cessation (OR=1.85), dietary changes (OR=1.35), and physical activity (OR=1.51).

Conclusions:

• Physician advice acts as a catalyst, enhancing the effectiveness of health behavior interventions.
• An integrated model combining physician counseling with detailed, individualized information supports sustained behavioral change.
• This approach highlights the synergy between direct patient-physician communication and targeted educational resources.
