Psychometric properties of the German version of the Traumatic Grief Inventory-Self Report Plus (TGI-SR+).
Background: Prolonged Grief Disorder (PGD) has been recognized as a mental health disorder and was added to the ICD-11 and DSM-5-TR. Despite the same name, both versions of PGD differ in symptom count, content, and diagnostic algorithm. A single instrument to screen for both PGD diagnoses is critical for bereavement research and care. The study aimed to evaluate the psychometric properties of the German version of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+), a self-report measure to assess PGDICD-11 and PGDDSM-5-TR symptoms.Methods: Out of a representative sample of the German general population (N = 2509), 1062 reported a significant loss and completed questions about sociodemographic and loss-related variables, the TGI-SR+, and a measure of health-related quality of life.Results: Item analyses demonstrated good item characteristics. Confirmatory factor analyses showed a good fit for two-factor models for PGDICD-11 and PGDDSM-5-TR. Omega values demonstrated good internal consistency. In support of concurrent validity, symptoms of PGDICD-11 and PGDDSM-5-TR were associated with worse health-related quality of life. In support of known-groups validity, symptoms of PGDICD-11 and PGDDSM-5-TR were significantly higher among women, people with a lower educational level, more recently bereaved, those who lost a spouse or child (vs. other person), and those who lost someone due to unnatural causes (vs. natural causes). ROC analyses showed optimal cut-off scores of ≥60 and ≥65 to screen for probable caseness for PGDICD-11 and PGDDSM-5-TR, respectively.Limitations: The analyses were based on a cross-sectional design, and data on retest-reliability and predictive validity is missing.Conclusion: Results support the reliability and validity of the German TGI-SR+ as a screening instrument for PGD in research.
期刊介绍：
The European Journal of Psychotraumatology (EJPT) is a peer-reviewed open access interdisciplinary journal owned by the European Society of Traumatic Stress Studies (ESTSS). The European Journal of Psychotraumatology (EJPT) aims to engage scholars, clinicians and researchers in the vital issues of how to understand, prevent and treat the consequences of stress and trauma, including but not limited to, posttraumatic stress disorder (PTSD), depressive disorders, substance abuse, burnout, and neurobiological or physical consequences, using the latest research or clinical experience in these areas. The journal shares ESTSS’ mission to advance and disseminate scientific knowledge about traumatic stress. Papers may address individual events, repeated or chronic (complex) trauma, large scale disasters, or violence. Being open access, the European Journal of Psychotraumatology is also evidence of ESTSS’ stand on free accessibility of research publications to a wider community via the web. The European Journal of Psychotraumatology seeks to attract contributions from academics and practitioners from diverse professional backgrounds, including, but not restricted to, those in mental health, social sciences, and health and welfare services. Contributions from outside Europe are welcome. The journal welcomes original basic and clinical research articles that consolidate and expand the theoretical and professional basis of the field of traumatic stress; Review articles including meta-analyses; short communications presenting new ideas or early-stage promising research; study protocols that describe proposed or ongoing research; case reports examining a single individual or event in a real‑life context; clinical practice papers sharing experience from the clinic; letters to the Editor debating articles already published in the Journal; inaugural Lectures; conference abstracts and book reviews. Both quantitative and qualitative research is welcome.
