Table 4 Cognitive Interview Results for the Symptom Checklist of the ACSD
From: Qualitative interviews to evaluate content validity of the ACTIV-2 COVID-19 Symptom Diary (ACSD)
Item on Initial Version (First 13 interviews) | Item on Revised Version (Last 17 interviews) | Selected Quotations Demonstrating Patients’ Interpretations of Each Item |
|---|---|---|
Cough | Cough | Have I had a cough in the past 24 hours. |
Shortness of breath or difficulty breathing at rest or with activity | Shortness of breath or difficulty breathing | Initial version of the ACSD: It just means is it hard to breathe when you’re sitting or lying, or you’re walking or moving around, do you have a hard time taking a breath. Initial version: I definitely think my responses would have been different if you had separate “at rest” versus “with activity,” but “shortness of breath” versus “difficulty breathing” I don't think would have changed it at all. Revised version: It’s asking if I have had any issues with my breathing. |
