Long COVID and Episodic Disability Study

Advancing the Conceptualization, Measurement and Knowledge of Episodic Disability with people living with Long COVID

Background

As the prevalence of Long COVID increases, more individuals are living with ongoing physical, mental and social health challenges after COVID-19 infection, known as disability. Questionnaires designed to capture this disability are important for health providers to understand the disability experienced so that they can provide care. Our research team has previously developed questionnaires in the context of adults living with HIV in Canada, US, Ireland and UK. This study builds on this work to apply lessons learned in other chronic and episodic conditions to understand and conceptualize disability experienced among adults living with Long COVID.

What is the purpose of this research study?

The purpose of this study is to gain a better understanding of the disability experiences among people living with Long COVID, to develop the Episodic Disability Questionnaire (EDQ), and assess how well this questionnaire can measure disability in people living with Long COVID.

Our specific aims are:

  1. To conceptualise the disability experiences (dimensions, trajectories, contextual factors and triggers that exacerbate or alleviate disability over time) among people living with Long COVID in Canada, UK, USA and Ireland, and to establish the Episodic Disability Framework in the context of Long COVID; and
  2. To develop and assess the measurement properties of an Episodic Disability Questionnaire (EDQ) while collecting foundational data on the presence, severity and episodic nature of disability and contextual factors (sex, gender, race, age, comorbidity, country) that may influence disability among adults living with Long COVID in Canada, UK, USA and Ireland.

This research is a collaboration between researchers in Canada, United Kingdom (UK), United States (US), and Ireland.   

What are the study methods?

This is a mixed methods study involving qualitative (aim 1) and quantitative measurement (aim 2) approaches with adults living with Long COVID in Canada, UK, USA and Ireland. In phase 1, we conducted semi-structured interviews with adults living with Long COVID to explore experiences of disability and establish an episodic disability (ED) framework in the context of Long COVID (n~10 each country). In phase 2, we will examine the validity (construct, structural) and reliability (internal consistency, test–retest) of the EDQ for use in Long COVID.

This research involves an international community–academic–clinical partnership building on foundational work in episodic disability among an international team with expertise in episodic illness, disability, measurement, COVID-19, Long COVID and rehabilitation.
