Psychological Test Development and Validation Workflow

This flowchart outlines the technical roadmap for developing and validating a psychological test, with the process rigorously divided into four stages. The first stage involves theoretical preparation and item generation: core concepts are defined through literature analysis, items are generated and refined with the assistance of LLAG, and an item pool is established through human-AI collaborative review. The second stage focuses on item optimization and pre-testing: items undergo expert review and revision before a small-scale pre-test is conducted to finalize the questionnaire for formal administration. The third stage covers formal administration and data cleaning, encompassing the distribution and collection of questionnaires as well as data processing. The fourth stage entails testing and analysis: item analysis and confirmatory factor analysis (CFA) are performed sequentially; if CFA fit indices do not meet standards, exploratory factor analysis and cross-validation CFA are conducted until the model meets the criteria, followed by final reliability and validity testing to ensure the test's scientific rigor and reliability.
