The traumatic grief inventory self-report version (TGI-SR): Introduction and perliminary psychometric evaluation

Year Published:

Abstract

Persistent Complex Bereavement Disorder (PCBD) is a disorder of grief newly included in the “Emerging Measures and Models” section of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, Citation2013). Prolonged Grief Disorder (PGD) is a disorder with similar symptoms, likely to be included in the forthcoming 11th edition of the International Classification of Diseases (ICD-11; World Health Organization, Citation1992). We developed the Traumatic Grief Inventory Self-Report version (TGI-SR), an 18-item measure, for the assessment of symptoms of PCBD and PGD in clinical and research settings. This study was an initial attempt to evaluate psychometric properties of the TGI-SR. To this end, the measure was administered to 327 patients of a mental health institute specialized in the treatment of psychopathology associated with loss and trauma. We found evidence that items of the TGI-SR (all 18 items, as well as the selection of 17 items representing PCBD criteria, and 11 items representing PGD criteria) loaded on one dimension. The TGI-SR demonstrated strong internal consistency. Elevated scores on the TGI-SR were significantly correlated with elevated scores on indices of psychopathology and lower quality of life, attesting to the concurrent validity. Receiver operation characteristic (ROC) analyses of the TGI-SR total score against provisional diagnoses of PCBD and PGD yielded a high area under the curve index suggesting that the TGI-SR total score can be used as an indicator for probable diagnoses of both PCBD and PGD. Results of this study provide initial evidence that PCBD and PGD symptoms may be readily and reliably measured using the TGI-SR.

What can help refugees process traumatic grief?

There is limited strong evidence on interventions that specifically target traumatic grief. –  Prolonged and traumatic grief are usually closely associated with post-traumatic stress disorder (PTSD) and therefore many interventions targeted PTSD with grief symptoms as an auxiliary diagnosis –  There appear to be some differences in interventions that target grief as a result of…

The impact of a parent-based prevention intervention on Mexican-descent youths’ perceptions of harm associated to drug use: Differential intervention effects for male and female youths

Parent training (PT) interventions reduce the likelihood of youth problematic behaviors, including drug use. However, the dissemination of culturally adapted PT interventions in low‐income Latina/o immigrant communities remains scarce. In this selective prevention study, we examined the extent to which exposure to CAPAS‐Youth, a culturally adapted version of the PT intervention known as GenerationPMTO©, resulted…
