Скачать или смотреть EPPP in Bite Sizes: Test Reliability and Validity

an in-depth examination of test construction, a foundational concept in psychology, specifically focusing on its relevance to the EPPP licensing exam. It explores the two major theoretical frameworks, classical test theory and item response theory, highlighting their differences in focus and assumptions. A significant portion is dedicated to explaining reliability—the consistency of test scores—detailing its estimation through various methods such as test-retest, alternate forms, internal consistency, and inter-rater reliability, and discussing factors influencing its magnitude. The source then thoroughly covers validity—whether a test measures what it intends to measure—presenting its three main types: content validity, construct validity, and criterion-related validity, with detailed explanations of concepts like the multitrait-multimethod matrix, factor analysis, and incremental validity as tools for their evaluation.
