Please answer the following questions based on the the following section.
Question 1. Is it an experimental study?
Question 2. Is it related to WRS (Wong's Respiratory Score)?

The results of the present psychometric evaluation build on the 
qualitative research evidence for the GRCD and, while preliminary, 
support its reliability, validity, responsiveness, and usefulness 
for assessing the symptoms of RSV in an outpatient population [9]. 

The next step in documenting the validity evidence for the revised 
GRCD is to confirm the present results using a single daily 
administration, explore the potential for further item reduction, 
verify the scoring, and more thoroughly evaluate its construct 
validity in a therapeutic clinical trial. 

Responder definition thresholds will be estimated to characterize 
meaningful change and provide guidance on the interpretation of 
GRCD scores and change.

The GRCD will be used and evaluated in future drug trials, with the 
expectation that it has the potential to collect important 
information from the parent or caregiver in a standardized manner 
capable of defining clinical improvement in RSV infection. 

This unique perspective can facilitate a more comprehensive 
evaluation of RSV disease symptoms and its treatment in clinical 
trials.
