Construct Validity Definition:
Construct validity is the extent to which a test measures the concept or construct that it is intended to measure.
Construct Validity Example:
There are many possible examples of construct validity. For example, imagine that you were interested in developing a measure of perceived meaning in life. You could develop a questionnaire with questions that are intended to measure perceived meaning in life. If your measure of perceived meaning in life has high construct validity then higher scores on the measure should reflect greater perceived meaning in life. In order to demonstrate construct validity, you may collect evidence that your measure of perceived meaning in life is highly correlated other measures of the same concept or construct. Moreover, people who peceive their lives as highly meaningful should score higher on your measure than people who perceive their lives as low in meaning.
