McCulloch et al 41 developed a questionnaire to clarify visual skills in neurologically impaired children likely to have profound VI.
It involves a 24-hour diet recall followed by a food frequency questionnaire to clarify information about usual consumption over the previous month.
Here, we conducted a cross-sectional questionnaire survey to clarify the associations between household background factors and parental behaviors.
To this end, we conducted two questionnaire surveys to clarify i) how IFs are addressed at neuroimaging research facilities in Japan and ii) the views of investigators and potential research participants regarding the handling of IFs.
We conducted two questionnaire surveys to clarify i) how IFs are addressed at neuroimaging research facilities in Japan and ii) the views of investigators and the general population regarding the handling of IFs.
The correct understanding of the questionnaire was ensured in two ways: Explanatory phrases and examples were included in the questionnaire in order to clarify specific Internet-related terms.
It was also necessary to apply a questionnaire in order to clarify some issues that have arisen.
The information gathered during these interviews and discussions informed the design of a questionnaire which aimed to clarify the extent to which the issues, attitudes and perceptions explored during the interviews and focus groups were applicable to a broader cross section of newly arrived women.
While participants were completing the questionnaires investigators were present to clarify any issues/questions and tried to ensure that the answers were as accurate as possible.
The instructions and layout of the items on each questionnaire were also investigated to clarify wording and improve usability.
