Relationships between beliefs about medications and adherence.
ABSTRACT The relationships between beliefs about medications, health literacy, and self-reported medication adherence are examined.
Patients from an inner-city hospital pharmacy completed an in-person, interviewer-assisted questionnaire that included the Morisky 8-item Medication Adherence Scale (MMAS-8), the Beliefs About Medicines Questionnaire (BMQ), and the Rapid Estimate of Adult Literacy in Medicine (REALM). Multivariable logistic regression was used to determine predictors of self-reported medication adherence as determined by the MMAS-8. Variables included in the model were summary scores from the BMQ, REALM, and patient or regimen characteristics that were significantly associated with the MMAS-8.
A majority of the 275 study participants were African-American (86.2%), were women (73.1%), and could read at less than a high school reading level (59.7%). The average age was 53.9 years. Approximately half of the patients (52.7%) reported low medication adherence (MMAS-8 score of >2). Multivariate analyses indicated several factors were associated with low self-reported adherence, including negative beliefs about medications, younger age, low medication self-efficacy, and hyperlipidemia. Health literacy was not independently associated with beliefs or adherence.
Patients who had negative beliefs about medications, who were <65 years of age, or who had low medication self-efficacy reported low medication adherence.

ABSTRACT: To investigate the beliefs of Norwegian outpatients about medicines, and to explore if some patient-specific factors and drug use are associated with the beliefs. Patients from an outpatient clinic for chronic cardiovascular diseases were referred by physicians to a pharmacist-led medication outpatient clinic. Here the patients were asked to complete the Beliefs about Medicines Questionnaire. 150 patients were included (mean age 70.0 years (range 31-91), 50 (33.3%) women), using a total of 1061 drugs. 91.2% strongly believed in the necessity of their medicines and 29.7% had strong concerns. Multivariate regression analyses showed that with an increasing number of drugs, the score for necessity was significantly increased (p<0.01). Women were significantly more concerned than men (p=0.03). The older the patient, the higher the score for general harm of medicines (p=0.01). Although the majority of the patients in this study believed in the necessity of their medication, one-third had strong concerns.European journal of hospital pharmacy.

ABSTRACT: Objectives. To assess adherence to long-term medications among patients in family medicine clinics and to evaluate relationship between adherence, beliefs about medications, medication information adequacy, and other factors. Methods. Interviewer assisted survey was conducted to assess adherence using the 8-item Morisky Medication Adherence Scale (MMAS-8), beliefs about medications using beliefs about medicine questionnaire (BMQ), and the patients' perception of medication information adequacy. Results. Of the 408 participants, 56.9% reported low adherence. Pearson's bivariate correlation showed positive association between MMAS-8 score and BMQ-specific necessity (r = 0.526 P < 0.001) and the perceived information adequacy (r = 0.568 P < 0.001), and there was negative association between adherence score and BMQ specific concerns, general overuse, and harm (r = -0.647, -0.466, and -0.663, resp.) (P < 0.001). Multivariable analysis revealed that age, number of medications, number of medical conditions, specific necessity and concerns beliefs, general harm beliefs, and perceived adequacy of medication information were independent predictor of adherence. Furthermore, specific beliefs explain 27.7% of the variance in adherence, while medication information adequacy explains 32.3% of the variance in adherence. Conclusion. The prevalence of low adherence among patients on long-term medications is high and it is related to negative beliefs about medications and to inadequate information given to patients about their medications.International journal of family medicine. 01/2014; 2014:479596.

ABSTRACT: Background: Identifying factors associated with adherence is of great value in clinical practice. The objective of this study was to investigate medication adherence, beliefs about medicines held by people with chronic illness and whether beliefs influence medication adherence. Methods: The study was carried out at primary health care clinic of the Palestinian Medical Military Services in Nablus, Palestine. The beliefs about medicines questionnaire was used to assess beliefs and Morisky medication adherence scale was used to assess adherence. Results: A total of 187 patients were interviewed. Most participants (79.6%) agreed or strongly agreed that their medications were necessary for their current health. However, 58.2% of the participants were concerned about having to take their medicines on a regular basis and 57.8% were concerned about becoming dependent on their medicines. None of the demographic and clinical variables was significantly associated with medication adherence. However, multivariate analysis showed that patients who had higher beliefs about medication necessity had higher odds (1.107 [1.023-1.197]) of being adherent. On the other hand, patients who had higher concern beliefs had lower odds (0.908 [0.845-0.975]) of being adherent. Conclusions: Beliefs about medicines are a major contributing factor to medication adherence.Journal of Family Medicine. 09/2014; 3(3):224-229.
