Psychometric properties of the Beliefs about Medicines Questionnaire (BMQ) in Mexican adults with asthma

[...]examples of the latter involve feelings of concern about the adverse effects that the maintenance treatment may generate (Kosse, Koster, Kaptein, de Vries, & Bouvy, 2019; Ponieman, Wisnivesky, Leventhal, Musumeci-Szabó, & Halm, 2009). Research has shown that the NCF is one of the best models to explain and predict treatment adherence behaviors in people with asthma and other chronic diseases (Dima, Hernández, Cunillera, Ferrer, de Bruin, & ASTRO-LAB Group, 2015; Holmes, Hughes, & Morrison, 2014; Lemay, Waheedi, Al-Sharqawi, & Bayoud, 2018; Lycett, Wildman, Raebel, Sherlock, Kenny, & Chan, 2018). Examples are the French adaptation of the questionnaire for patients with HIV infection and diabetes (Fall, Gauchet, Izaute, Horne, & Chakroun, 2014), the Turkish version for people with COPD, asthma (Arikan, Duman, Kargın, Ergin, Horne, Karakurt, & Eryuksel, 2018) and Behçet syndrome (Çınar, Tekgöz, Çınar, & Yılmaz, 2016), Greek for patients in primary care (Komninos, Micheli, Roumeliotaki, & Horne, 2013), the Polish version for those with cardiovascular problems (Karbownik, Jankowska-Polańska, Horne, Górski, Kowalczyk, & Szemraj, 2020), the Chinese version for patients with stroke, diabetes and rheumatoid arthritis (Wei, Chapman, Li, Li, Li, Chen, Bo, Chater, Horne, 2017), and the Spanish version for patients with diabetes, hypertension (Beléndez, Hernández, Horne, & Weinman, 2007), and psychiatric illnesses (De las Cuevas, Rivero, Perestelo, González, Pérez, & Sanz, 2011). [...]in the case of the BMQ-General in Spanish (Beléndez et alia, 2007), the item "Natural remedies are safer than drugs," appears grouped in the harm subdimension, not in the overuse subdimension (to which belongs originally), so this last dimension could be weakened. [...]the aim of this study was to evaluate the psychometric properties of the BMQ in Mexican adults with asthma.
