There are several strategies to reduce the impact of response bias in epidemiological research:
Careful Questionnaire Design: Using neutral wording, avoiding leading questions, and including both positively and negatively phrased items can help minimize response bias. Validation Studies: Cross-checking self-reported data with objective measures or external records can help assess the accuracy of the responses. Blinding: Whenever possible, blinding participants and researchers to the study hypothesis can reduce bias. Training Interviewers: Providing thorough training to interviewers can help ensure that they collect data consistently and without introducing bias.
