Background:
A questionnaire is a commonly used data collection method and is a very crucial part of the research. However, designing a questionnaire can be a daunting task for postgraduate students.
Methods:
This manuscript illustrates the various steps required in questionnaire designing and provides an insight into the essentials of questionnaire construction and validation. Data from a questionnaire should be able to comprehend the objectives of the study; else it may lead to wrong interpretation or bias, decreased power of study and inability to generalize the study results.
Conclusion:
Since it is equally important to verify the usefulness of the designed questionnaire, the article briefly describes the process of psychometric evaluation of a questionnaire.
