MIMIC model for Patient Health Questionnaire - 9 (PHQ-9).
The base Multiple-Indicator Multiple-Cause (MIMIC) model consists of a confirmatory factor model with the additional direct effect of group (language) on the latent depression factor serving to control for group differences on the level of the latent depression factor. For differential item functioning (DIF) analysis, the direct effect of group on PHQ-9 items is assessed for each item separately by regressing items, one at a time, on language, controlling for any differences in the overall level of the latent depression factor between groups.
