Suppose that you want to evaluate the discriminant validity of a self-report Laziness scale.Which of the following results for this scale would be evidence that it has good discriminant validity?

Question

Quizplus · Accepted Answer

The best choice for evidence of discriminant validity would be a correlation of 0 or close to 0 with observer reports of a construct that is theoretically unrelated to laziness, such as sociability. Option D shows a correlation of 0 between the Laziness scale and observer reports of sociability, providing evidence for discriminant validity. Options A and B both show a correlation of -.50 with observer reports of constructs that are theoretically related to laziness, indicating poor discriminant validity. Option C shows a correlation of 0 with observer reports of hardworkingness, which may indicate discriminant validity, but it is not as strong as option D because hardworkingness may still be somewhat related to laziness. Finally, option E is incorrect because the correlations in question are related to validity, not reliability.
