The relationship between medication adherence and affective temperaments in patients with congestive heart failure

Introduction: Congestive heart failure (CHF) is a serious condition and lack of medication adherence is one of the most common problems in the treatment of patients with CHF. This study aimed to determine the relationship between medication adherence and affective temperaments in patients with CHF. Material and methods: This cross-sectional study was performed on 150 patients, who were referred to the cardiology clinic of Ali Ibn Abi Talib Hospital of Zahedan, Iran in 2017–2018. Morisky Medication Adherence Scale (MMAS-8), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego auto questionnaire (TEMPS-A), and Beck Depression Inventory-II (BDI-II) were used to collect data. For statistical analysis, SPSS-18 was used. Logistic regression was done for modeling the relationship between medication adherence. Results: Generally, 54% of the patients were euthymic, while 16%, 23.33%, and 6.66% of them suffered from mild, moderate, and severe depression, respectively. The medication adherence was high, moderate, and low in 30.66%, 46%, and 23.33% of the patients, respectively. There was a significant relationship between medication adherence and depressive (P = 0.049), cyclothymic (P = 0.01), and irritable (P = 0.01) affective temperaments. Only BDI-II score (P = 0.018) was identified as predictors of drug adherence. Conclusions: Despite the statistically significant relationship between depressive, cyclothymic, and irritable temperaments and adherence, affective temperaments cannot be considered as a predictor of adherence in patients with CHF.
