What are the reasons given in the textbook for concluding that the NIO-PI-R is a “good” test?

What will be an ideal response?

Answer: It is not necessary for the student to cover all the points made in the textbook about this test, but a good answer will cover several of the following points:
o It is reliable as demonstrated by a high Cronbach’s alpha (.56-.81) for each of its factors and facets.
o It has a high test-retest reliability over a three-month period.
o With regard to validity, its main factors account for close to 60% of variability.
o Criterion validity was tested when, for example, the test was shown to produce low scores on Agreeableness when given to drug abusers.
o Convergent and discriminant validity was demonstrated by correlating scores on the NEO-PI-R with other valid personality tests such as the Extraversion scales of the Eysenck Personality Inventory.
o Test generalizability was indicated by its usefulness in various populations and clinical settings.
