The present study aimed to analyse the factorial structure of the Cognitive Emotion Regulation Questionnaire (CERQ) using exploratory factor analysis (EFA) in police officer candidates from Catalonia (Spain). A second objective is to analyse the reliability and internal consistency of the nine factors of the CERQ as determined by dimensionality analysis. Conclusions: CERQ has good psychometric indices, making it a good tool for the assessment of emotional stability. The labels should be reconsidered depending on the profession. Recode for non-clinical samples. The Test-Retest analysis doesn't identify a profile of police officer candidates "adaptive" vs "less adaptive", because the people in the sample are very similar. Validation of CERQ in a sample of police candidates is a step forward in studying emotional coping strategies in the assesment and trainning of police candidates. In this regard, the integration of different coping strategies prove to be a good predictor of performance in police trainning.
