A substantial amount of evidence regarding comorbidity among mental disorders has been accumulated during the last years. Moreover, it has been identified that there is a great variability within nosological categories. These limitations of categorical systems lead to the development of the transdiagnostic paradigm which contemplates the existence of underlying processes common to different diagnoses. The process of emotional regulation is currently the focus of many investigations. It is estimated that it is associated with the development and maintenance of 75 % of DSM mental disorders. Emotional dysregulation is being studied particularly as a common factor in depression and anxiety, the two most prevalent disorders in Argentina. Related to this, transdiagnostic protocols aiming this process have been studied in the last years at a global level. The Unified Protocol has been developed by Barlow from a transdiagnostic perspective aiming to offer an evidence based intervention that could be faithfully used in heterogeneous groups. It was created for emotional disorders with a specific focus on emotional dysregulation, contemplating comorbidity and heterogeneity. This makes the Unified Protocol a proper and valid intervention for the most prevalent disorders in Argentina. The objective of this study was to explore the familiarity of mental health practitioners, of public hospitals in the metropolitan area of Buenos Aires, with the emotional dysregulation construct and protocols designed for the treatment of patients with these characteristics. Moreover, the degree in which clinicians approach psychotherapy research was evaluated. For this purpose, a cross-sectional descriptive study was carried on. A questionnaire was designed with 40 questions (25 with closed answer and 15 with short open answer) that investigated five thematic areas: demographic characteristics, therapeutic approach, knowledge about the emotional dysregulation construct and treatment protocols, knowledge about the transdiagnostic paradigm and approach to empirical research. The questionnaire was completed by 75 practitioners (psychologists and psychiatrists) from public hospitals of the metropolitan area of Buenos Aires. After analyzing the results, it can be said that the most prominent theoretical framework from which practitioners work in public hospitals is psychoanalysis. The most prevalent diagnoses are anxiety and depression and comorbidity is frequent (M = 2.23, SD = .707). When studying the familiarity to the construct of emotional dysregulation, it was observed that even though most of them reported knowing the emotional dysregulation construct (89.3 %), when asked to conceptualize a person with intense and long-lasting emotional distress and difficulty in controlling their behavior and recognizing their emotions, very few mentioned difficulties in the regulation of emotions (13.51 %). Individual format treatment was the most chosen by psychologists for patients with these characteristics (69 %). Psychiatrists reported pharmacotherapy as the most chosen treatment (87.5 %). Group format is not frequently used. In regards to transdiagnostic protocols designed to intervene in emotional dysregulation, they are very poorly implemented. Dialectical Behavioral Therapy was reported to be known by 80 % of the sample, but used by 33.9 %, while the Unified Protocol was referred to be known by 34.7 % and used by 7.69 % of them. On the other hand, the gap between clinical practice and research seems to be wide. Less than half of the practitioners reported reading empirical research (44 %). And the trans-diagnostic paradigm is known by 46.7 % of practitioners. When asked to mention the most influential authors in their practice, Freud and Lacan (classical psychoanalytic authors) were mentioned by the majority. The courses chosen to continue their training are mostly psychoanalytic and participation in international congresses is low (10.45 %). These results show the need to look for ways to encourage the use of evidence-based inter-ventions in public hospitals and specifically the dissemination of transdiagnostic protocols with evidence for emotional dysregulation, being emotional disorders the most prevalent.
