To ensure a questionnaire accurately reflects students' oral health behaviors, we need to use a mix of methods. First, it's important to pilot test the questionnaire with a small group of students to spot any issues early on. After that, we can use statistical methods like factor analysis to check if the items are grouping together as they should. Additionally, involving experts in oral health and education can help confirm that the questions are relevant and cover all necessary aspects. For instance, a study by Muñoz-Sepúlveda et al. (2024) emphasizes how crucial the translation and validation processes are for ensuring health questionnaires really measure what they’re intended to.
