Symptom Burden Questionnaire™ for Long COVID

The Symptom Burden Questionnaire™ for Long COVID system (SBQ™-LC) is a patient-reported outcome (PRO) measure and multi-domain item bank that has been developed according to international best-practice and regulatory guidance. The SBQ™-LC system measures symptom burden in adults (18+ years) with post-acute sequelae of COVID-19 (PASC), also known as “post COVID-19 condition” or “Long COVID”.

About the SBQ™-LC
The SBQ™-LC system measures symptom burden in adults (18+ years) with “post-acute sequelae of COVID-19 (PASC), also known as “post COVID-19 condition” or “Long COVID”. The SBQ™-LC is composed of 17 independently functioning, unidimensional scales. Sixteen scales measure symptom burden (i.e., symptom presence, severity, or frequency) across different symptom “domains” and one scale measures symptom impact on daily life.
This modular approach means all scales can be administered to collect comprehensive symptom data or that only those scales relating to symptom domains of particular interest need be administered.
Conversion of raw scores to a common metric (0-100) allows easy comparison of scores across the different symptom domains.

Development and validation of the SBQ™-LC
Development and validation of the SBQ™-LC
The SBQ™-LC was developed according to internationally recommended guidance in a multi-phase mixed-methods study. The SBQ™-LC was developed from a systematic review of Long COVID symptoms, pretesting with clinicians (n = 10), and cognitive debriefing interviews with adults with lived experience of Long COVID (n = 13). Two hundred and seventy-four adults with Long COVID field tested the SBQ™-LC via the Aparito Atom5™ platform.
A description of the development and initial validation of the SBQ™-LC has been published (Hughes et al 2022).
