Does adherence-related support from physicians and partners predict medication adherence for vasculitis patients?

Area of Science:

• Rheumatology
• Autoimmune Diseases
• Health Psychology

Background:

• Medication adherence is crucial for managing rare, systemic autoimmune conditions like vasculitis.
• Few studies have investigated the mediators influencing medication adherence in these patient populations.
• The Information-Motivation-Behavioral Skills model provides a framework for understanding adherence behaviors.

Purpose of the Study:

• To examine the mediating roles of depressive symptomatology and medication adherence self-efficacy.
• To investigate the relationship between adherence support (physician and partner) and changes in medication adherence.
• To determine if physician and partner support differentially impact medication adherence in vasculitis patients.

Main Methods:

• A cohort of 172 vasculitis patients completed baseline and follow-up questionnaires.
• Data collected included medication adherence and perceived adherence support.
• Bootstrapped mediation analyses were employed to test the proposed mediation models.

Main Results:

• Medication adherence self-efficacy significantly mediated the association between physician support and improved medication adherence.
• Depressive symptomatology did not mediate the relationship between physician support and adherence.
• Neither depressive symptomatology nor adherence self-efficacy mediated the effects of partner support on medication adherence.

Conclusions:

• Physician support can enhance medication adherence in vasculitis patients, primarily through increased self-efficacy.
• Interventions aimed at improving physician-patient communication regarding medication can positively impact adherence.
• Further research is needed to understand the role of partner support in medication adherence for rare autoimmune diseases.
