International audience. IntroductionBecause changing personal beliefs about treatment could help improve adherence, having a validated tool for identifying these beliefs is important.ObjectiveThis study sought to validate the French version of the Beliefs about Medicines Questionnaire (BMQ-f©).MethodData were gathered among 253 patients with type 2 diabetes and 123 HIV patients with the help of self-reported questionnaires, including the Beliefs about Medicines Questionnaire, a French adherence assessment, and some demographic variables.ResultsConfirmatory factor analyses show the French version of the BMQ has the same factorial structure as the English original in both diabetes and HIV samples. All items load on their expected factor namely specific-necessity, specific-concern, general-harm, and general-overuse. Moreover, each scale revealed good internal consistency and retained the psychometric qualities of the original version. These satisfactory properties were consolidated by predictive validity data that demonstrate the impact of treatment beliefs on adherence levels.ConclusionFindings are discussed in light of previous diabetes and HIV studies. The French BMQ proved to be a good way of quickly identifying inaccurate beliefs about treatment. It could be a useful tool in French clinical practice, such as in patient education.
