Question

clifton had been experiencing a number of psychological issues, so he decided to go to a psychiatrist to see what was wrong. dr. a told him he had major depressive disorder. he decided to seek a second opinion. dr. b diagnosed him with generalized anxiety disorder. wanting yet another opinion, he went to dr. c, who told him he was obsessive - compulsive. this demonstrates poor
test - retest reliability.
concurrent validity.
descriptive validity.
inter - rater reliability.

Explanation:

Inter-rater reliability refers to the consistency of judgments or diagnoses between different evaluators (in this case, psychiatrists). When three different doctors give Clifton entirely different diagnoses, it shows that the diagnostic process lacks consistency across raters, which is poor inter-rater reliability. Test-retest reliability involves consistency over time with the same rater, while concurrent and descriptive validity relate to whether a measure assesses what it is supposed to, not consistency between raters.

Answer:

inter-rater reliability.
