Vasculitis Illness Perception (VIP) Study

Completed

• Conditions: Behcet's Disease; CNS Vasculitis; Wegener Granulomatosis; Giant Cell Arteritis; Henoch-Schoenlein Purpura; Microscopic Polyangiitis; Takayasu's Arteritis; Churg-Strauss Syndrome; Polyarteritis Nodosa

• Registration Number: NCT02190916
• Lead Sponsor: University of South Florida

Brief Summary

The purpose of this study is to learn about how patients with vasculitis think about their illness and to assess to what extent patient perceptions of illness are associated with physical, mental, and social functioning

Detailed Description

All patients enrolled in the Vasculitis Clinical Research Consortium's Contact Registry were invited via email to participate in this study. The Contract Registry includes people who self-identify as having one of the following types of vasculitis: granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg-Strauss syndrome, polyarteritis nodosa, Takayasu's arteritis, giant cell arteritis, Behcet's disease, Henoch-Schöenlein purpura, or CNS vasculitis. People voluntarily enroll in this Registry with the understanding that they will receive information about clinical studies for which they might be eligible. The introductory email included basic information about the study and all of the required elements for informed consent in a brief format. Once participants agreed to participate in the study, then they were directed to the online questionnaire.

When completing the questionnaire, patients were asked a series of questions. Some of the follow-up questions depended on initial answers. The questionnaire content was included as an appendix. The online questionnaire version was thoroughly tested for usability.

It was expected that most participants would require approximately 20-30 minutes to complete the questionnaire.

The survey data is stored by the Rare Diseases Clinical Research Network Data Management and Coordinating Center (DMCC) at the University of South Florida. The data is de-identified. Names or other personal health information are not be collected.

Primary Outcome Measures

Name	Time	Method
Composite measure to include Illness perceptions, fatigue and function in patients with systemic vasculitis with further emphasis on causal beliefs about disease onset and relapse triggers.	1 year after the study is closed to enrollment	The outcome measure(s) will be evaluated based on the cross-sectional online questionnaire. The questionnaire is the only study procedure for this online patient contact registry protocol and will be the sole analysis tool for both the primary and secondary outcome measures.

Secondary Outcome Measures

Name	Time	Method
Composite measure of potential associations between illness perceptions, fatigue and function in patients with systemic vasculitis	1 year after the study is closed to enrollment	The outcome measure(s) will be evaluated based on the cross-sectional online questionnaire. The questionnaire is the only study procedure for this online patient contact registry protocol and will be the sole analysis tool for both the primary and secondary outcome measures.
