Then, the questionnaire seems something like this: Dear all, Hello, I have developed an instrument (questionnaire) in which a scenario is followed by four different reactions.
The problem I have is in validating this questionnaire.
May I run factor analysis by turning the questionnaire into a Likert scale in which the respondents read each reaction and then identify on the Likert scale the extent to which they might exhibit each reaction in that particular occasion (mentioned in the scenario)?
The respondents need to choose one of those reactions as their dominant response in that particular occasion (each reaction exemplifies a particular approach).
The research question I'm going to respond is if there is any relationship between respondents' gender (and some other variables) and their choice of particular approaches.
Validation should be done within two weeks to determine test-retest reliability.
Before validating a questionnaire, hypotheses should be established regarding anticipated differences in scores between various subgroups of the population being studied, as well as regarding any correlations with other studies.
Continue Reading The same population sample should not be used for the validation of the questionnaire and the actual clinical study, but the population used for validation should be representative of the population to be used in the study.
Sample size is typically 50 to 100 participants, though a larger sample size is sometimes required for validation of a questionnaire.
For example, the climate and culture of an organisation is known to be central to optimising employee wellbeing, productivity and innovation.
Similarly, it is important to select executives or employees with certain character traits and dynamics for them to function effectively in their roles.
