Quizplus · Accepted Answer

The best evidence for discriminant validity is that Dr. Sheffield's measure is not strongly correlated with measures that it should not be related to, such as impulsivity. This suggests that the measure is tapping into a unique construct related to pathological gambling and not just measuring general impulsivity or other constructs. Choices C and D suggest a strong relationship with constructs that may be related to gambling addiction or behavior, while choice B is not directly related to the construct of pathological gambling.
