Knowledge of and adherence to antipsychotic medications among individuals diagnosed with schizophrenia

Abstract

Background Aims: the purpose of this study is to identify the level and correlation of knowledge of and adherence to antipsychotic medications among individuals diagnosed with schizophrenia. Materials and Methods: A cross-sectional, correlational design was used to collect data from a convenience sample of 365 patients referred to psychiatric outpatient units. Data collected using Understanding of Medication Questionnaire and Morisky Medication Adherence Scale. Results: Lack of knowledge about antipsychotic medications was found among patients diagnosed with schizophrenia. The majority of patients reported low levels of adherence to their medications. A significant positive correlation was found between individuals’ knowledge and their adherence level. Being younger, single, had higher education, and had full-time job were significantly associated with higher level of knowledge and adherence to antipsychotic medications. Conclusions: Poor adherence to medications is associated with lack of knowledge about medications inferring the need for strategies and interventions to increase patients’ knowledge and awareness about their medications. Psycho-educational interventions related to antipsychotic medications are priority to mental health nurses. There should be also emphasis on patients' awareness, insight, and attitudes toward their medications.
