The Cognitive Emotion Regulation Questionnaire is one of the most widely used instruments to measure cognitive emotion regulation, and its psychometric properties have been evaluated in various studies and cultural contexts. However, the 9-factor internal structure originally proposed for the scale measures does not present consistent evidence in the literature. The exclusive use of the confirmatory factor model in previous literature may largely explain this inconsistency. In the present research, we propose to estimate innovative measurement models for this questionnaire, the exploratory structural equation models. For this purpose, we worked with a large sample of Argentines and compared the fit of the models. The results favored the exploratory structural equation models, indicating that we are not observing indicators that reflect simple factorial structures. This refined understanding can ultimately improve the reliability of Cognitive Emotion Regulation Questionnaire scores in clinical settings, enhancing the quality of patient care and treatment outcomes.
