 	abstract = "Several studies have pointed out a high prevalence of Complicated Grief (CG), PostTraumatic Stress Disorder (PTSD), and depression among the bereaved. As for impairment in grief, two diagnostic proposals have been receiving scientific attention in the last years: Prolonged Grief Disorder (PGD), from the 11th edition of the International Classification of Diseases (ICD-11) and Persistent Complex Bereavement Disorder (PCBD), from the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Although international literature widely explores bereavement experience, there are only a few studies in Brazil concerning the subject. Knowledge regarding clinical symptomatology and the risk factors for developing psychopathologies are imperatives to understand this phenomenon in the named context. Similarly, diagnostic measurements that contemplate the current proposals for impairment in grief are not available in the Brazilian Portuguese language.  Furthermore, gaps concerning the effects of exposure to factors related to death, such as seeing the death scene or the dead body, are still contradictory in the existing literature, which demands further investigation. Therefore, this dissertation aimed to carry out the validation of Traumatic Grief Inventory Self-Report (TGI-SR), a diagnostic instrument for evaluating both symptoms of PGD and PCBD, and to investigate the presence of CG, PTSD, and depression in the Brazilian population. This dissertation is divided into two studies (1 and 2), each generated an empirical article. The collection of both studies was conducted simultaneously, using an online platform (Qualtrics). The final sample comprised of 304 bereaved individuals. Instruments for evaluating sociodemographic and loss characteristics, CG, PTSD, and depression symptoms were used. Study 1 conducted the adaptation and validation process of the TGI-SR, using a mixed design with a psychometric and cross-sectional method. The study observed the following steps: translation, cultural adaptation, content validation by experts, cognitive interviews with the clinical and non-clinical sample, final test in the target population, and backtranslation. Exploratory Factor analysis, Receiver Operating Characteristic (ROC) analysis, and Item Response Theory (ITR) analysis were conducted to evaluate the Brazilian version's internal structure, cut off points, and discriminative power of the items. The findings originated from this study demonstrate that TGI-SR can be considered a reliable and valid tool to assess PGD and PCBD. Study 2 aimed to verify CG, PTSD, and depression symptoms in the collected sample and to investigate the effects of loss characteristics and exposure to death factors in these symptoms. Descriptive analysis, ttests, and logistic regression models were utilized to investigate differences and odds ratios to present the evaluated clinical symptoms. Results point to the risks of being exposed to death factors concerning CG and PTSD symptoms and the risks of losing a first-degree relative through violent ways. This dissertation's findings provide important information about mental health after a bereavement in Brazil, accentuating the importance of evaluating and implementing primary care interventions in death situations. Additionally, we strive to contribute to the development of public policies to support this population.",
