Selected psychological factors and medication adherence in patients with rheumatoid arthritis

Medication adherence and predictive factors among patients with rheumatoid arthritis: A COM-B model guided structural equation modeling analysis

OBJECTIVE

To assess medication adherence of patients with rheumatoid arthritis (RA) and explore predictive factors under the guidance of the Capability, Opportunity and Motivation to Behavior (COM-B) model.

METHODS

A cross-sectional study was conducted among 221 RA patients conveniently recruited from rheumatology outpatient clinics of a university-affiliated hospital in China. Data about patients' sociodemographic and disease characteristics, medication adherence, functional disability, social support, beliefs about medicines, self-efficacy, and depression were collected via self-administered questionnaires. The influence of factors within the COM-B model on medication adherence were analyzed by the structural equation model.

RESULTS

The mean score of medication adherence was 63.19 (SD 8.83), and 214 participants (96.8%) were considered non-adherent to their medication regime. Greater functional disability, higher social support, more positive beliefs about medicines, higher self-efficacy, and lower depression were significantly positively associated directly or indirectly with medication adherence, explaining 66% of the total variance.

CONCLUSION

Patients with RA demonstrate poor medication adherence. Essentials in improving medication adherence are delaying the occurrence of disability, promoting social support, shaping beliefs about medicines, enhancing self-efficacy, and relieving depression.

PRACTICE IMPLICATIONS

The value of integrated interventions targeting the drivers and barriers to medication adherence identified in this study should be further explored.

An Overview on Causes of Nonadherence in the Treatment of Rheumatoid Arthritis: Its Effect on Mortality and Ways to Improve Adherence

Rheumatoid arthritis is one of the most prevalent musculoskeletal disorders that, when insufficiently treated, results in detrimental sequelae including joint damage and reduced quality of life. Poor patient adherence to medication is a significant blockade to effective management. The purpose of this review is to highlight and discuss the factors responsible for defiance of antirheumatic medication and ways to overcome these barriers. Education level, health literacy, cohabitation status, multi-morbidities, complicated drug regimen, intermittent co-payments, prescribed regimen adverse effects, and cognitive impairment are a few among many common barrier factors leading to poorer outcomes in rheumatoid arthritis. While there is an abundance of inhibitory factors leading to worsening disease progression, they each can be easily dealt with an effective approach at the beginning or during the treatment course to ensure a better outcome.

The Influence of Selected Psychological Factors on Medication Adherence in Patients with Chronic Diseases

Background: Insufficient adherence to treatment is a relevant problem. This study aims to determine the impact of health locus of control, stress coping style and level of mindfulness on medication adherence in patients with a chronic illness. Methods: The study included 768 people. The diagnostic survey involved the use of: Medication Adherence Questionnaire (MAQ), Multidimensional Health Locus of Control Scale (MHLC), The Coping Inventory for Stressful Situations (CISS), and The Mindful Attention Awareness Scale (MAAS). Results: Participants were divided into two subgroups, i.e., adherent (n = 219) and non-adherent (n = 549). We observed significant differences between the subgroups in age, BMI, sex, place of residence, education, and for all MHLC subscales, two CISS subscales and MAAS. The identified medication adherence variables were: female gender (OR = 1.55), BMI (OR = 0.95), MHLC/Internal (OR = 0.95), CISS/Emotional (OR = 1.03), MAAS (OR = 0.97). Conclusions: A strong internal health locus of control, a higher level of mindfulness and a lower level of emotional-stress coping style increase the likelihood of adherence with medication recommendations in patients with chronic diseases.
