A Tool for Decision-Making in Norm-Referenced Survey Questionnaires with Items of Ordinal Variables

In order to arrive at a conclusion, setting up a cut-off point is necessary for opinion-based questionnaires on health care utilization, facilitating factors, barriers and also for assessing Knowledge, Attitude and Practice. This study has demonstrated on how to formulate a tool for decision-making in Norm-referenced survey questionnaires and readjust their cut-off points to incorporate the population variation for items containing ordinal variables. This procedure will help the researchers to perform finer adjustments in the cut-off values of any Norm-referenced survey instrument based on the local population data and in situations where no gold-standard instrument is available for comparison.
