Developing and validating a questionnaire
Abstract Questionnaires are the most widely used data collection methods in educational and evaluation research.This article describes the process for developing and testing questionnaires and posits five sequential steps involved in developing and testing a questionnaire: research background, questionnaire conceptualization, format and data analysis, and establishing validity and reliability.The ACB will aim to be a multidimensional measure of concerning behaviours in ASD incorporating self-report, parent/carer, teacher/employer and clinician report versions that can be used across the lifespan and spectrum of intellectual ability.Methods and analysis This study will be guided by the methods described in the US Food and Drug Administration Guidance for Industry Patient-reported Outcome Measures.Making an individual question is a tedious task and validating this questionnaire is another challenge which at times is over looked.Consideration should be given accordingly on whether the questionnaire will measure quantitative or qualitative data, and what would be its mode of administration.
Questionnaire Development: A questionnaire is a tool to obtain information from respondents.
It is extremely important for a researcher to know the importance of a proper questionnaire and whether it measures what it is intended to measure.
Composing of a questionnaire is always much more complex than expected and great attention is required to its flow, format and length.
In a review of 748 research studies conducted in agricultural and Extension education, Radhakrishna, Leite, and Baggett (2003) found that 64% used questionnaires.
They also found that a third of the studies reviewed did not report procedures for establishing validity (31%) or reliability (33%).
