Background. Emotion Regulation (ER) involves any explicit or implicit process that may alter the emotion felt, its duration and expression, and is a transdiagnostic factor of vulnerability involved in the etiology and maintenance of different emotional disorders. The Cognitive Emotion Regulation Questionnaire (CERQ) assesses nine cognitive strategies involved in ER and is a valuable tool. Its popularity and wide use led to the development of two abbreviated versions: a version with 18 items (two items per factor) and a 27-item version (three items per factor).
Objective. To analyze the psychometric properties of both versions in the Argentinean population.
Design. The research design was instrumental. The factor structure of the CERQ-18 and CERQ-27 as well as the reliability of the scores and the construct of each dimension were evaluated. In addition, we gathered validity evidence for its relationship with other variables by associating the CERQ scores with Difficulties in Emotion Regulation Scale (DERS) scores.
Results. The CERQ-18 presented more consistent evidence regarding its internal structure (adequate fit indices and factor loadings of moderate magnitude) and reliability. Given that the association of the two versions with the DERS is similar, we recommend that the 18-item version be used.
Conclusion. The CERQ-18 has quite similar psychometric properties to the CERQ-27 in the general population of Argentina and the findings contribute to an understanding of its internal structure.
