Objective: The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) measures the most recent prolonged grief disorder (PGD) symptom sets defined in the 11 edition of the International Statistical of Diseases and Related Health Problems (ICD-11) and the text revision of the fifth edition of the Diagnostical and Statistical Manual of Mental Disorders (DSM-5-TR). However, the TGI-SR+ has not yet been translated and validated in Chinese. This study aims to evaluate the psychometric properties of the Chinese translation of the TGI-SR+.

Most studies examining prolonged grief disorder (PGD) in people bereaved during the COVID-19 pandemic are focused on psychopathology. However, mental health encompasses both absence of psychopathology and presence of well-being. This is the first study examining symptom profiles of early PGD and subjective mental well-being in 266 Dutch adults recently bereaved during the pandemic.

Firefighters face regular exposure to potentially traumatic events, which is associated with the development of post-traumatic stress disorder (PTSD) and depression. Despite the high comorbidity, there remains limited understanding of the co-occurrence of PTSD and depression in terms of symptom patterns. Due to the unique stressors added by the COVID-19 pandemic, it is relevant to also understand this comorbidity in light of the impact of the COVID-19 pandemic.

Aim: The extent to which recent potentially traumatic events (PTEs) hinder the recovery from pre-existing mental health problems is largely unknown. The same applies to the extent to which non-recovery from pre-existing mental health problems increases the risk of posttraumatic stress disorder (PTSD). The aim of the present study is to gain insight in these effects.

The COVID-19 pandemic caused multiple stressors that may lead to symptoms of adjustment disorder. We longitudinally examined relationships between risk and protective factors, pandemic-related stressors and symptoms of adjustment disorder during the COVID-19 pandemic, as well as whether these relationships differed by the time of assessment. The European Society for Traumatic Stress Studies (ESTSS) ADJUST Study included = 15,169 participants aged 18 years and above.

Article Synopsis
  • Road traffic accidents (RTAs) often lead to posttraumatic stress disorder (PTSD), with about 20% of survivors affected, highlighting the need for effective mental health services (MHSs).
  • In a study of 259 Dutch RTA victims, only 26% accessed MHSs, with a higher usage rate of 56% among those with probable PTSD, demonstrating that increased PTSD symptoms correlate strongly with MHS use.
  • The study identified a treatment gap where 17.8% of participants had unmet needs for care, often due to misconceptions about their problems and financial concerns, indicating a need for improved accessibility and awareness of mental health options.

Participating in a criminal trial may increase the likelihood of developing psychopathology. In 2021, people bereaved by a plane disaster (flight MH17) had the opportunity to deliver a victim personal statement (VPS) in Dutch court. This longitudinal mixed-method study examined different aspects of 84 bereaved people's experiences with VPS delivery.

With the release of the text revision of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5-TR), criteria for Prolonged Grief Disorder (PGD) were included. This necessitates studying grief trajectories based on these criteria. This is the first study examining latent trajectories of DSM-5-TR-based PGD symptom levels and testing whether specific risk factors (e.

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+).

Background: Around 10% of bereaved youths experience symptoms of prolonged grief disorder (PGD). Recently, PGD was included in the two main classification systems for mental disorders: the ICD-11 and DSM-5-TR. Assessing PGD symptoms in youth is currently hindered by the lack of instruments for ICD-11 and DSM-5-TR criteria.

Prolonged grief disorder (PGD) has been included in the International Classification of Diseases (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders 5 Text Revision (DSM-5-TR). Loss-related avoidance behavior perpetuates grief and effective interventions for prolonged grief symptoms target such avoidance behavior. Yet, behaviors characterized by approach of loss-related cues (i.

Article Synopsis
  • The study addresses the psychological impact of ambiguous loss, particularly concerning relatives of missing persons, by creating the Ambiguous Loss Inventory Plus (ALI+).
  • Eight relatives of missing individuals and seven experts evaluated the clarity and relevance of the ALI+ items, scoring them positively (averaging above 3.7).
  • The initial findings suggest that the ALI+ effectively captures the experiences associated with ambiguous loss, but more testing is required to validate its effectiveness.

Objective: This randomized-waitlist controlled trial is the first study examining short-term effects of a self-guided online grief-specific cognitive behavioral therapy (CBT) in reducing early persistent complex bereavement disorder (PCBD), posttraumatic stress disorder (PTSD), and depression symptoms in adults bereaved during the COVID-19 pandemic.

Method: Sixty-five Dutch adults, bereaved at least three months earlier during the pandemic, with clinically-relevant PCBD, PTSD, and/or depression symptoms, were allocated to a treatment (n = 32) or waitlist condition (n = 33). Telephone interviews were conducted to assess PCBD, PTSD, and depression symptoms (using validated instruments) at baseline, post-treatment, and post-waiting period.
