Question

Quizplus · Accepted Answer

Criterion-related validity refers to how well a measure correlates with an outcome or criterion that it should theoretically be related to. In this case, the outcome is engaging in binge and abnormal eating behaviors, which the test is measuring accurately, indicating good criterion-related validity. Content validity refers to how well a measure covers all aspects of the construct it is intended to measure, and internal consistency refers to how well the items within a test are consistently measuring the same concept. Test-retest reliability refers to how consistent the results of a test are over time. While these are all important aspects of a good test, they are not specifically indicated by the results described in the question.
