A solution for factorial validity testing of three-item scales: An example of tau-equivalent strict measurement invariance of three-item loneliness scale
Ultra-short scales are increasingly popular in surveys. Congeneric model fit of a three-item scale cannot be tested with Confirmatory Factor Analysis (CFA) without additional assumptions because the number of degrees of freedom is equal to zero. A more rigorous tau-equivalent model, assuming equalit...
