Strengths and Limitations
The strengths of the present study include a large cross-sectional
US-wide representative population sampling approach with a response rate
over 90% and a margin of error around 4%.
The key limitation is that we conducted no piloting and validation of
the questions 4 and 5 deployed in our survey. A mitigating circumstance
is the fact that the questions were either binary or simple
multiple-choice queries leaving little room for interpretation.
