Emotional Regulation is one of the most important professional competencies in the training of aspiring firefighters. As indicated by Rhys (2019) the intense demands that are imposed on Fire Service staff in conjunction with the benefits and risks associated with the emotions experienced and the strategies used to manage them, suppose a real challenge in this profession. In this line, Assunçao (2013) affirmed that firefighters and other professional collectives related to medical emergencies or rescue operations, live with an exposure to stressful situations that increase the risk of developing different psychopathological disorders. An important psychometric evaluation of the emotional regulation at the cognitive level was the Cognitive Emotion Regulation Questionnaire (CERQ). This instrument has been extensively used by the scientific community, and has been translated and psychometrically adapted to a large number of culturally diverse languages such as Persian, Chinese or Japanese. In Spanish there are different validations of their psychometric properties, both in Latin America and Spanish populations. CERQ has been used in a wide range of cohorts such as: people with fibromyalgia (Reche, 2019), patients with different psychopathological disorders (Potthoff et al, 2016), different age cohorts (Navarro-Loli, 2020) [5] and university students (Domínguez y Medrano, 2016).
