Health Coaching (HC) quality varies significantly, with most studies showing medium or low quality. Higher quality HC interventions are linked to better health outcomes, highlighting the need for consistent, evidence-based approaches.
Area of Science:
- Health Sciences
- Behavioral Medicine
- Public Health
Background:
- Lifestyle-associated chronic diseases are increasing globally.
- Health Coaching (HC) is a popular intervention, but definitions and quality vary.
- Lack of consensus hinders comparison of HC interventions.
Purpose of the Study:
- Assess core elements in studies identifying HC interventions.
- Develop the Health Coaching Quality Index (HCQI) to evaluate HC intervention quality.
- Examine the relationship between HCQI scores and health outcomes.
Main Methods:
- Integrative review of manuscripts from Scopus and PubMed.
- A priori criteria used for study inclusion (e.g., intervention studies with coaching control groups).
- Developed HCQI based on theory-driven criteria for key coaching parameters (e.g., goal setting, questioning).
Main Results:
- 54 manuscripts were analyzed; most evaluated weight, BMI, physical activity, and biomarkers.
- A majority of HC interventions were rated medium (41%) or low (35%) quality by HCQI.
- Only 24% of interventions were rated high quality, with heterogeneity in delivery and strategies.
Conclusions:
- The HCQI effectively differentiates HC intervention quality.
- Significant heterogeneity exists in HC intervention methods and consistency.
- Higher quality HC interventions showed a greater association with positive health outcomes.
