This domain employs rigorous methodologies to develop, confirm, and improve instruments that quantify latent psychological constructs. The value of psychometrics stems from its application across diverse fields like educational assessment, clinical diagnostics, and organizational psychology. Origins and Development The origins of psychometrics can be attributed to the late 19th and early 20th centuries, mainly influenced by pioneers such as Francis Galton and Alfred Binet. Galton’s work on the measurement of individual differences and Binet’s development of the first intelligence test established the basic concepts of psychometric theory. Further developments were marked by the introduction of the Spearman-Brown formula and factor analysis by Charles Spearman, which furthered the understanding of test reliability and the structure of intelligence (Spearman, 1904). Core Principles of Psychometric Theory Central to psychometrics are the concepts of reliability, validity, and standardization. Reliability denotes the consistency of a measure, encompassing various forms such as test-retest reliability, inter-rater reliability, and internal consistency (Cronbach, 1951). Validity, on the other hand, relates to the degree to which an instrument measures what it claims to measure, covering content validity, criterion-related validity, and construct validity (Messick, 1995). Standardization entails the establishment of norms and uniform procedures to guarantee the comparability of scores across different populations. Theoretical Models in Psychometrics The measurement
