Factors that influence medication adherence in women with fibromyalgia: A path analysis

Abstract

Aims: To investigate the relationships between depression symptoms, perceived stigma, disease severity, patient-provider communication and medication adherence in fibromyalgia patients. The objectives were to explore how these factors influence treatment adherence and to develop a comprehensive model illustrating their interconnections. Background: Fibromyalgia is a chronic pain syndrome with fatigue, sleep issues and idiopathic pain. Medication adherence is limited by insufficient symptom relief, side effects and costs. Stigma further complicates fibromyalgia. Disease severity affects patient-provider communication. Associations between depression, stigma, severity, communication and adherence in fibromyalgia are unclear. Design: A cross-sectional, correlational study. Methods: The STROBE guidelines for cross-sectional studies were followed. Participants included Hebrew-speaking participants who were members of two Facebook groups: ‘Shades of Purple’ and ‘Fibromyalgia- Get to Know!’ Between February and April 2022. They undertook evaluations using The Patient Health Questionnaire-9 to gauge depression symptoms, assessed perceived stigma, utilised The Revised Fibromyalgia Impact Questionnaire to determine disease severity, employed The Patient Reaction Assessment questionnaire for patient-provider communication, and used the 8-item Morisky Medication Adherence Scale (MMAS-8). Associations between the variables were explored using Pearson's correlations and path analyses. Results: The study included 141 women with fibromyalgia, aged 22 to 76 years. Most reported having a stable partner (69.5%) and 75.2% had children. The treatment adherence levels were as follows: 53.2% (N = 75)—low, 33.3% (N = 47)—medium and 13.5% (N = 19)—high. Depression positively correlated with stigma. Stigma negatively correlated with patient-provider communication. Patient-provider communication positively correlated with treatment adherence. A significant negative indirect effect of depression on treatment adherence through stigma and patient-provider communication was found. Conclusions: Perceived stigma and patient-provider communication played a mediating role in the relationships between depression and treatment adherence among women with fibromyalgia. Relevance to Clinical Practice: Addressing stigma related to fibromyalgia and effective patient-provider communication can positively influence treatment adherence.
