Final answer:
The test Kristoff took has high face validity because it superficially appears to measure depression based on sadness and crying, but may not capture the full range of depressive symptoms.
b is correct
Step-by-step explanation:
Considering Kristoff's symptoms and the results of the test for depression which focused only on sadness and crying, the correct statement about the test is: b. it has high face validity. Face validity refers to the extent to which a test appears to measure what it's supposed to measure, based on a superficial examination of its content.
Despite Kristoff scoring as not depressed on the test, his symptoms such as loss of interest, poor concentration, loss of appetite, difficulty sleeping, and fatigue suggest that he does indeed experience depressive symptoms. Therefore, while the test may look like it's assessing depression on the surface, it may not capture the full range of depressive symptoms, making its face validity potentially misleading in this context.
