“…The 18‐item Traumatic Grief Inventory‐self report (TGI‐SR) was developed by Boelen and colleagues (Boelen et al, 2019; Boelen & Smid, 2017) in Dutch bereaved samples to assess symptoms of Persistent Complex Bereavement Disorder (PCBD: the former terminology used by the DSM‐5), symptoms of PGD as described by Prigerson et al (2009), and PGD as per Maercker et al (2013), the precursor of the current ICD‐11 PGD criteria. The TGI‐SR has demonstrated strong psychometric qualities across different bereaved samples, such as a clinical (Boelen & Smid, 2017), disaster‐bereaved (Boelen et al, 2018) and community bereaved samples (Baş et al, 2020; Boelen et al, 2018). In terms of factor validity, a unidimensional structure of TGI‐SR was found in Dutch sample (Boelen & Smid, 2017).…”

More recently, the prolonged grief disorder (PGD) has been recognized as a mental health disorder following bereavement, which is distinct from depression and PTSD. However, the number and proposed symptom items vary across the ICD‐11 and the DSM‐5‐TR criteria for PG. The Traumatic Grief Inventory‐Self Report Plus (TGI‐SR+), which is an updated version of the TGI‐SR, is currently the only robust instrument that assesses PG according to the ICD‐11 and DSM‐5‐TR criteria. For research and clinical use among French‐speaking countries, the forward‐backward procedure was applied to translate the TGI‐SR+ into French language. Exploratory factor analysis and parallel analysis converged towards a two‐dimensional structure for the TGI‐SR+, representing adaptation difficulties and traumatic separation distress. However, items mapping onto ICD‐11 and DSM‐5‐TR criteria for PG represented a one‐dimensional structure. Findings based on item response theory method provided strong evidence for discriminative characteristics of the items. The internal reliability was excellent for the TGI‐SR+ (McDonald's ω = 0.97) and ICD‐11 and DSM‐5‐TR criteria for PGD (McDonald's ω = 0.95). We also demonstrated a very high temporal stability for the TGI‐SR+ total score (ICC = .91, p < 0.0001) and ICD‐11 PGD and DSM‐5‐TR PGD (ICC = 0.90, and ICC = 0.88, ps < 0.0001, respectively). The concurrent validity of the instrument was also demonstrated, such that the TGI‐SR+ total score and all combinations were positively and significantly associated with the levels of depression, anxiety and post‐traumatic stress symptoms. However, the effect sizes were moderate. We conclude that for research and clinical use among French bereaved populations, the TGI‐SR+ is a sound tool with very good psychometric properties.

“…Diante disso, sugere-se a realização de novos estudos para que o instrumento tenha mais evidências de validade. Por fim, o ponto positivo do ITL-BR é que ele é capaz de identificar a presença de luto traumático persistente, podendo ser uma ferramenta importante tanto para o desenvolvimento de pesquisas na área, como também para orientar intervenções com esta população, independente do tipo de situação que ocasionou a morte da pessoa próxima (Baş et al, 2020;Maciejewski et al, 2016).…”

“…Os objetivos específicos foram verificar: (a) as evidências de validade com base no conteúdo (b) as evidências de estrutura interna (análise fatorial confirmatória); (c) as evidências de validade relacionadas às variáveis externas (fobia social; estresse; medo); (d) os valores de precisão do instrumento e (e) se o instrumento poderia ser aplicado também em uma amostra em luto por perder alguém em decorrência do COVID-19. Como hipótese norteadora, esperava-se que a estrutura unifatorial apresentasse bons índices de ajuste e de precisão e relação positiva com a presença de fobia social, estresse e medo (APA, 2013;Baş et al, 2020;Boelen & Smid, 2017;Boelen et al, 2018;Lee & Neimeyer, 2020).…”

O objetivo do presente estudo foi verificar as evidências de validade da versão reduzida adaptada para o português do Brasil do Traumatic Grief Inventory, por meio de uma análise fatorial confirmatória e relação com variáveis externas, além de aferir a precisão e presença de invariância. A primeira etapa consistiu na adaptação e avaliação por juízes especialistas da versão traduzida. Após a avaliação, a versão piloto foi aplicada em cinco participantes da população-alvo para avaliação semântica e de conteúdo, sendo nomeado de Inventário de Luto Traumático (ILT-BR). Em seguida, 211 brasileiros, que passaram por um processo de luto, responderam aos seguintes instrumentos: Questionário Sociodemográfico, Questionário de Autopercepção de Saúde Mental e ILT-BR. O ILT-BR apresentou bons índices de ajuste e precisão, se correlacionando positivamente com estresse, medo e pensamentos obsessivos, sem variação entre grupos. A partir destes resultados, conclui-se que há evidências de que o ILT-BR apresenta boas propriedades psicométricas.

The International Classification of Diseases Eleventh Edition (ICD‐11), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM‐5‐TR), now include prolonged grief disorder (PGD). Since criteria for PGD in both classification systems differ from prior proposed grief disorders and each other, the validation of a single instrument to screen for prolonged grief (PG) symptoms of both new diagnoses is critical for bereavement research and care. Therefore, we evaluated the psychometric properties of the Swedish version of the Traumatic Grief Inventory Self‐Report Plus (TGI‐SR+). Two‐hundred and forty‐eight bereaved parents completed questions about sociodemographic and loss‐related variables, the TGI‐SR+, and symptom measures of post‐traumatic stress (PTS), depression and an older measure of PG symptoms, the Prolonged Grief Disorder‐13 (PG‐13). Confirmatory factor analyses showed that a one‐factor model best fit DSM‐5‐TR and ICD‐11 PG symptoms and the analyses of the internal consistency and inter‐item correlations showed that these symptoms could be reliably assessed. In support of convergent validity, DSM‐5‐TR and ICD‐11 PG symptoms correlated with symptoms of PTS, depression and PG assessed with the PG‐13. In support of known‐groups validity, DSM‐5‐TR and ICD‐11 PG symptoms were higher among lower educated (vs. higher educated) participants and related negatively to time since loss. ROC analyses showed optimal cut‐off score of ≥71 and ≥72 to determine probable caseness for DSM‐5‐TR and ICD‐11 PGD, respectively. Results support the reliability and validity of the Swedish TGI‐SR+ as a screening instrument for PG in research and bereavement care.
