CODESP Test Validation and Reliability 5

Question 1

According to the Society for Industrial-Organizational Psychology (SIOP) Principles, which of the following is the LEAST acceptable justification for using a test with adverse impact?

Accepted Answer

A belief that the test 'looks' job-related to applicants

Answer

Face validity — the perception that a test looks job-related — is not a sufficient scientific or legal justification for using a test with adverse impact.

Question 2

Coefficient alpha will be artificially INFLATED when:

Accepted Answer

Items have very high inter-correlations due to item overlap or redundancy

Answer

When items are redundant or essentially paraphrase one another, alpha rises artificially without reflecting true reliability.

Question 3

A test manual reports a test-retest reliability of 0.85 with a 6-month interval. Compared to a 2-week interval, the 6-month coefficient is MOST likely:

Accepted Answer

Lower, because real changes in the construct may occur over time

Answer

Longer time intervals allow true changes in the measured attribute to occur, which lowers test-retest reliability coefficients.

Question 4

Which approach to establishing validity is MOST appropriate for a newly developed test when no local criterion data are yet available?

Accepted Answer

Validity generalization / transportability argument

Answer

When local criterion data are unavailable, validity generalization allows practitioners to use accumulated evidence from prior studies to justify test use.

Question 5

The four-fifths (4/5) rule in the Uniform Guidelines is used to evaluate:

Accepted Answer

Whether adverse impact exists in selection rates between groups

Answer

The 4/5 rule compares the selection rate of a protected group to that of the highest-selected group to detect adverse impact.
