Reliability, Validity & Cultural Fairness
Prior to beginning work on this discussion, read Chapters 5 and 6 in the textbook and the required articles for this week. Take the role of a psychological examiner administering a standardized test of intelligence to Johnny, an 8-year-old boy, as a part of a research project. Carefully review the ABS300: Week Two Assessment Scenario. In your initial post, begin by describing your current understanding of the concept of intelligence. Based on your description of intelligence, evaluate Johnny’s response in comparison to the responses identified as correct in the standardization manual. Decide whether or not to score Johnny’s answer as correct or incorrect. Explain your rationale. Specify how scoring Johnny’s responses exactly by the manual might impact his true score on the intelligence measure. Analyze the “four seasons of the year” test item in terms of each of the following psychological measurement concepts: reliability, predictive validity, content validity, and cultural fairness. Evaluate the standards in the APA’s Ethical Principles of Psychologists and Code of Conduct that address testing bias and the strategies for multicultural assessments discussed in the article by Horin, Hernandez & Donoso (2012) in light of the current scenario. Conclude your post by explaining how you would interpret the assessment results to Johnny and his parents.
