Significance of Content validity
Content validity is the degree to which items within a questionnaire effectively represent the concepts they aim to measure. It encompasses the comprehensive assessment of the range of skills or knowledge targeted by the test and evaluates whether the items accurately reflect the intended construct. Expert evaluations play a crucial role in establishing content validity, ensuring that all relevant aspects of the construct are captured and that the instrument is appropriate for its intended use in research or practice.
