Integrating a physical activity (PA) counselor into primary care significantly boosts patient motivation and confidence for increased PA. This approach offers intensive support beyond brief physician counseling, improving long-term behavior change.

Area of Science:

  • Health Promotion
  • Behavioral Medicine
  • Primary Care Research

Background:

  • Primary care settings offer opportunities to enhance patient motivation and confidence for increasing physical activity (PA).
  • Physician-led PA counseling shows some success, but sustained behavior change often necessitates more intensive interventions.
  • Physicians typically lack the specialized training and time for intensive PA counseling.

Purpose of the Study:

  • To outline the rationale, methods, and interventions for a physical activity counselling (PAC) randomized controlled trial (RCT).
  • To assess the impact of integrating a dedicated PA counselor into a primary care practice.
  • To evaluate the effectiveness of brief PA counseling versus brief PA counseling plus intensive PA counseling.

Main Methods:

Visualization of Intensity Levels to Reduce the Gap Between Self-Reported and Directly Measured Physical Activity

Published on: March 7, 2019

  • A randomized controlled trial (RCT) involving 120 insufficiently active adults (aged 18-69) recruited during primary care visits.
  • Two arms: (i) brief PA counseling (2-4 min) by a healthcare provider, and (ii) brief PA counseling plus intensive PA counseling (3 months) by a PA counselor.
  • Evaluation using the RE-AIM framework, measuring psychological mediators, PA participation, quality of life, and physical/metabolic outcomes.

    • Main Results:

    • The study is ongoing; therefore, definitive results are not yet available.
    • The design focuses on psychological mediators of behavior change, a key component of the intervention.
    • Data collection includes a comprehensive range of outcomes to evaluate the intervention's impact.

    Conclusions:

    • The PAC project is an innovative, theory-based approach to promoting PA in primary care.
    • The study aims to provide valuable lessons for future public health interventions, theories, and research in PA promotion.
    • Integration of PA counselors in primary care shows promise for enhancing PA participation and health outcomes.
