Construct validity and reliability1/12/2024 In other words, you have a problem with construct validity. In this kind of situation you could say that you don't have a single unidimensional construct you have a family of somewhat related but different constructs. Different approaches to measuring the construct produce different results because each gets at different aspects or because each comes from a different perspective.
