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

Setting up a cut-off point is necessary for opinion-based questionnaires on health care utilization, facilitating factors and barriers to arrive at a conclusion and also for assessing Knowledge, Attitude and Practice. This study and shows 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 continuous 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.
