The content validity index, Cronbach’s alpha (α) and intraclass correlation coefficient were used. Results: The indicators achieved 89.9% adequacy, 82.5% clarity, internal consistency was α = 0.80, and the test-retest correlation was 0.93. Conclusion: The instrument showed acceptable validity and reliability and can be used for the evaluation of Health Promotion interventions.
