La desregulación emocional (de) fue identificada como uno de los principales procesos involucrados en el surgimiento y mantenimiento de los trastornos emocionales. A su vez, los trastornos emocionales son los más prevalentes mundialmente, volviendo a la de un objeto de estudio de gran relevancia. El presente trabajo consiste en la adaptación y validación de la Escala de Dificultades en la Regulación Emocional (Difficulties in Emotion Regulation Scale, ders) (Gratz & Roemer, 2004), para ser usada en población general del Área Metropolitana de Buenos Aires. Se realizó un estudio transversal con 315 participantes entre 18 y 65 años. La consistencia interna resultó adecuada (α = 0.936; ω = 0.938). Se llevó a cabo un análisis factorial confirmatorio mediante el paquete Lavaan, quedando la escala conformada por 30 ítems que se ajustan a las seis dimensiones originales. También se presenta evidencia de validez convergente y discriminante, la capacidad de discriminación de los ítems, diferencias por sexo y edad, y valores normativos para adultos del Área Metropolitana de Buenos Aires. La adaptación al español de la ders representa una herramienta válida y confiable para medir distintos aspectos del proceso de regulación emocional.

[Background] Due to the COVID-19 pandemic, Argentina has been under mandatory quarantine. We have aimed to investigate the state of mental health of the Argentine population and the behaviours adopted to cope with mental distress during quarantine. [Method] An online survey was conducted using a probabilistic sampling technique and stratified according to the geographic regions of the country. The survey covered days 7-11 (n = 2,631) and days 50-55 (n = 2,068) after compulsory quarantine. The psychological impact was measured using the 27-item Symptom CheckList (SCL-27), which provides a Global Severity Index (GSI). An ad hoc questionnaire registered problematic, healthy and other behaviours. Two network models were estimated using a Mixed Graphical Model. Data from the two periods were compared and analysed. [Outcomes] Higher GSI scores and greater risk of experiencing mental disorder were found in Period 2 as compared with Period 1. The lowest GSI scores were associated with physical activity in both periods, and meditation and yoga in Period 1. Drug users reported the highest GSI scores in both periods. The Network Comparison Test confirmed a significant change in symptomatology structure over the two quarantine periods. [Conclusion] This study showed that psychological symptoms and the risk of experiencing mental disorder increased significantly from Period 1 to Period 2. Network analysis suggested that the quarantine might have brought about changes in the relationships between symptoms. Overall results revealed the relevance of mental health and the need to take mental health actions upon imposing quarantine during the current COVID-19 pandemic.
