To enhance or maintain validity and trustworthiness in the qualitative research the researcher needs to adopt the following techniques: How to enhance validity in qualitative research To establish construct validity the researcher should have good knowledge of the statistical procedures. It measures the instrument validity by developing a link between the questions and the outcome variables by testing the coefficient of variation. Construct validityĬonstruct validity determines the validity in a more objective manner. Its use is very common in the field of psychology and personal attributes can be very accurately tested with this validity.
It also predicts how valid the scale can be in the future, this is a very fast way to measure or establish the validity of a test. It can also refer to testing the same test on two groups concurrently to establish the validity of the test.
Concurrent and predictive validityĬoncurrent validity measures the extent to which the results of a scale are concurrent with the results of a similar study in the past. No objective conclusion can be drawn thus as any change in questions will yield a different result. If different questions will be developed the link between the objectives and the instrument will not remain same. The problem with face validity is that the logic on the basis of which the researcher develops questions is subjective and hence it varies from person to person. It should also be noted that the questions on the scale should cover all the objectives of the study.
The questions on the scale should have a logical reason why they have been developed, i-e they should provide answers to the objectives. Face validity measures the validity of the instrument by creating a logical relationship between the questions on the scale and the objectives of the study.
