Our results showed significant discrepancies between subjective and objective measures of adherence, which likely reflect the influence of social desirability bias in self-reported measures and different concepts of adherence between patients/caregivers and haemophilia experts. Additionally, our results allow us to hypothesize that studies on adherence to prophylaxis in haemophilia relying exclusively on information from self-reports and questionnaires may substantially overestimate adherence levels.
