POSB377 Preliminary Psychometric Evaluation of the Respiratory Syncytial Virus Infection Intensity Impact Questionnaire (RSV-IIIQ) in Adults

A new self-report tool, the RSV Infection Intensity Impact Questionnaire (RSV-iiiQ), was adapted from an existing influenza symptom instrument (Osborne et al, 2011) consistent with FDA patient-focused drug development draft guidance. The RSV-iiiQ includes 29 questions in four hypothesized subscales (Respiratory Symptoms/Systemic Symptoms/Daily Activity Impacts/Emotional Impacts). The study aim was to evaluate preliminary psychometric properties of the RSV-iiiQ.
