Psychometrics — subject primer
This page is a Chinese-language primer on psychometrics. The outline below summarises it in English.
Overview
Psychometrics is the science of measuring psychological attributes: how tests are constructed, how their scores are interpreted, and how good they must be before anyone relies on them.
Core themes
Test construction and item analysis, reliability and measurement error, validity and validation, norms and score interpretation, classical test theory versus item response theory, measurement invariance and fairness.
Key theories and figures
Spearman on reliability and general intelligence, Cronbach on coefficient alpha, Thurstone and Likert on scaling, Rasch and Lord on item response theory, Messick on validity.
Research methods
Factor analysis and structural modelling, item response modelling, reliability generalisation, differential item functioning, and computerised adaptive testing.
Applications
Educational and clinical assessment, personnel selection, scale development and cross-cultural adaptation, and outcome measurement in research.
In China
Test use follows the psychology ethics code and professional standards; domestic norms and Chinese-language instrument development remain active areas, especially in clinical and educational settings.
Appendices
A quick-reference table of indicators and standards, plus further reading (textbooks, journals, organisations and standards).
