“…The results obtained in this study are in line with the previous work of our research group, which emphasized the role played by the variables of the health belief model in adherence to the prescribed psychiatric treatment ( De las Cuevas and de Leon, 2017 , De las Cuevas et al, 2017 , De las Cuevas et al, 2016a , De las Cuevas and Peñate, 2015a , De las Cuevas et al, 2016b , De Leon and de las Cuevas, 2017 ), although our prior research is limited because we used the Morisky Medication Adherence Scale of 8 items as an instrument for assessing adherence ( De las Cuevas & Peñate, 2015b ). Nevertheless, this new and better adherence tool, allowing the evaluation of each patient's psychoactive drug, has helped us to further establish evidence that socio-demographic and clinical variables of the patient may have no important role in adherence, while the patient's attitudes and beliefs toward his/her medication may have a very strong role.…”
