OBJECTIVE: To design and validate a questionnaire to measure caries management based on the Capability, Opportunity, and Motivation Behavior model (COM-B) and the International Caries Classification and Management System (ICCMS™).

METHODS: A combination of Cariology and Psychology experts developed a 79-item pool that measured the COM-B components according to the ICCMS™ caries management recommended behaviours. After face and content validation and a pilot study, two samples of Colombian dentists participated: clinicians (n = 277) and clinical-practice educators (n = 212).

RESULTS: Using parallel analysis and exploratory structural equation modelling (ESEM), the questionnaire was reduced to a 47-item 5-factor instrument that demonstrated good internal consistency and validity properties, including a robust factor structure, measurement invariance across samples and high predictive validity of ICCMS™ recommended behaviours. Scales' mean scores showed that dentists were conducting recommended behaviours "most-of-the-time" (Behavior), showed high confidence in their ability to conduct these behaviours (Capability) and considered recommendations as highly relevant (Opportunity-Relevance), while their appraisals of the available resources (Opportunity-Resources) and remuneration (Motivation) were notably lower.

CONCLUSION: Overall, the findings highlight the practical utility of the COM-B ICCMS™ Questionnaire in understanding the potential antecedent variables that may explain dentists' behaviours related to caries diagnosis and management and in suggesting avenues for achieving a positive change in their behaviour.
