Psychometric properties of a psychological assessment
Evaluate the psychometric properties of a psychological assessment of your choice. For this paper, each student will select ONE psychological test that is NOT covered in the textbook or in any class presentations. Students will use the Mental Measurements Yearbook (MMY) database available through Liberty University’s Jerry Falwell Library website to find resources to aid in evaluating the test. In grading your paper, your instructor will look at the following:
Evaluation of the Psychometric Properties of the Test
Your evaluation of the test should include the following areas of consideration:
1. Purpose of Test: What is the purpose of the test (personality, screening, diagnosis, marriage counseling, placement for children, etc.)? Who developed it and why? How is it used?
2. Type of Test/Scoring: What kind of items does the test utilize (T/F, Likert, etc.)? How is the test scored? What kind of score(s) do respondents receive (percentile rank, z score, T score, total and /or subscale scores?)
3. Normative Sample: Describe the normative sample (including the number of participants and their known demographic characteristics). Indicate whether or not the normative sample is adequately representative of the intended test-takers.
4. Administration: How is the test administered? Paper and pencil? Computer based? Who can purchase/administer the test (i.e., minimum qualifications)?
5. Reliability: Correctly use terms from the textbook/course materials to define the types of evidence for reliability reported in the review articles, and provide the specific numerical values of the reliability statistics. If no reliability data are provided, then explain what type of evidence for reliability you would need in order to fully evaluate the test.
6. Validity: Correctly use terms from the textbook/course materials to define the types of evidence for validity reported in the review articles, and provide the specific numerical values of the validity coefficients. If no validity data are provided, then explain what type of evidence for validity you would need in order to fully evaluate the test.
Justification for Selecting the Test
Your justification for selecting the test should include the following areas of consideration:
1. Explain why you selected this test for review. Specifically, explain how the test is relevant to what you are doing now and/or your future career plans.
2. Explain how the test that you chose fits in with the goals and responsibilities of Christian professionals who might utilize the test. Choose at least one scriptural citation to support your argument.
