A scale gives you nearly identical scores every time you take it, but the scores fail to predict any relevant outcome. This scale is:

MC1 pt

A. Reliable but not valid — consistency alone does not establish that it measures what it claims

B. Valid but not reliable

C. Both reliable and valid, since consistency implies accuracy

D. Neither reliable nor valid

The MMPI-2 was constructed using empirical keying, which means items were selected because they:

MC1 pt

A. Statistically discriminated between criterion groups, regardless of whether the content seemed theoretically sensible

B. Were rated by experts as appearing to measure the intended construct

C. Loaded onto five factors in a factor analysis of trait adjectives

D. Were derived deductively from psychoanalytic theory

The MBTI's popularity in business settings despite weak psychometric support is best explained by:

MC1 pt

A. Strong face validity — it looks meaningful and its descriptions feel accurate, which is the weakest form of validity evidence

B. Superior test–retest reliability compared to the NEO-PI-R

C. Robust predictive validity for job performance

D. Its use of empirical keying against criterion groups

Reverse-keyed items are included on personality inventories primarily to counter which response bias?

MC1 pt

A. Acquiescence — the tendency to agree with items regardless of their content

B. Social desirability — the tendency to present oneself favorably

C. Extreme responding — the tendency to use only the endpoints of a scale

D. Malingering — the deliberate feigning of symptoms

Establishing construct validity requires evidence that a measure correlates with what it theoretically should AND fails to correlate with what it shouldn't. These two requirements are called:

MC1 pt

A. Convergent and discriminant validity

B. Concurrent and predictive validity

C. Face and content validity

D. Internal and external reliability

Which are legitimate arguments in defense of projective tests? (Select all that apply.)

Multi2 pts

A. They are considerably harder to fake than transparent self-report items

B. They may access implicit motives that people cannot or will not self-report

C. Implicit motives measured by the TAT predict different outcomes than self-attributed motives, suggesting they tap something distinct

D. They consistently demonstrate higher inter-rater reliability than objective inventories

E. Their validity is uncontested across all scoring indices

An employer proposes screening all job applicants with the MMPI-2. Identify at least two ethical or legal problems with this plan, and explain what would make an employment-testing program defensible instead.
