(1) Background: The Covid-19 pandemic has put our healthcare systems to the test, exposing their vulnerability and demanding a high degree of commitment and dedication from healthcare teams to confront and contain the disease. In this sense, nursing professionals have played a prominent role in the treatment of complex cases that have required hospitalisation and have manifested pre-existing health complications or mortality. This unprecedented situation made it difficult to regulate the emotional impact and manage grief, often turning it into a traumatic grief whose psychological and emotional manifestations are increasingly evident but very little researched in the current context. (2) Purpose: Validation of the definition, defining characteristics and related factors for the proposal of the nursing diagnosis of professional traumatic grief. (3) Method: Based on Fehring’s content validation model, the label name, defining characteristics and other related factors were agreed upon by Spanish experts. (4) Results: The content validity index was 0.9068. A total of 21 defining characteristics were validated by the experts, as all of them scored above 0.6. With respect to the related factors of the proposed 10, all were validated. (5) Conclusion: The present study supports the proposal to develop a nursing diagnosis for professional traumatic grief. The use of standardised language is only the first step in establishing professional traumatic grief as a diagnostic category.

Introduction: Of the serious problems that characterise the current crisis in Spain, the most alarming and revealing is unemployment, which, despite being so common, continues to be quite a negative experience for most people, often with serious negative effects on their biopsychosocial health. The perpetuation of this situation has given rise to a new syndrome of the unemployed. If these effects of economic downsizing are accompanied by the magnitude of the current situation brought about by COVID-19, the results can be devastating for the individuals and families experiencing it. Objective: To compare the symptoms of the unemployed syndrome in three population groups. Method: Three groups were studied: short-term unemployed (n = 91), long-term unemployed (n = 150), and those unemployed during the COVID-19 pandemic (n = 94). Unemployment syndrome was assessed with the Unemployment Syndrome Scale (USS). The three population groups were contacted through web pages, social networks, etc. and answered the instruments online in a single session. Once the responses were obtained, their information was encoded in a database and analysed through the SPSS v. 21 program. Population groups were compared using the ANOVA analysis and the Bonferroni post hoc test. Results: The unemployed individuals who lost their job during the pandemic reported higher scores in the symptoms of the Unemployed Syndrome Scale compared to the long- and short-term unemployed individuals. ANOVA analyses for symptoms of USS were all significant in the different groups considering a significance level of <0.005. Participants who were unemployed for less than one year had lower scores in the USS than the long-term unemployed participants and those unemployed during the COVID-19 pandemic that reported a significantly higher number of symptoms in the USS.
