Construction of a questionnaire based on the Health Action Process Approach for psycho-social cognitive determinants of parents in brushing children's teeth in the Netherlands.

Our results did not fully support the constructs of the HAPA model. To support the HAPA constructs, modification to the subscales risk perceptions, intention, action planning, action control and self-reported behaviour are suggested. With these adjustments, the reliability and validity of the questionnaire could be significantly improved".
