Internet gaming disorder (IGD) is a growing public health concern, with longitudinal studies linking it to a range of negative outcomes, including psychological distress and poor academic achievements. While the trauma model has been applied to other addictive behaviors, little is known about the relationship between childhood trauma, trauma-related symptoms, and IGD symptoms. This preliminary study investigated whether childhood betrayal trauma would have a stronger relationship with IGD symptoms than non-betrayal trauma and whether IGD symptoms would be associated with interpersonal stress and trauma-related symptoms.

Previous studies showed that dissociation and dissociative disorders (DDs) are prevalent and are associated with considerable individual and social consequences. There are ongoing debates regarding whether dissociation is a response to betrayal trauma across cultures and whether dissociation can be explained by maladaptive coping. Additionally, little is known about the clinical features of individuals with DDs in the Chinese context.

Article Synopsis
  • The study investigates the reliability and mental health associations of single-item self-rated mental health (SRMH) measures in Chinese populations, using data from Hong Kong, Taiwan, and psychiatric inpatients.
  • It found that SRMH demonstrated moderate to good reliability, with a high positive correlation with self-esteem and a negative correlation with depression and other mental health disorders like borderline personality disorder and PTSD.
  • Overall, the findings support the effectiveness of using single-item SRMH assessments for understanding mental health perceptions in Chinese communities.

Objective: The dissociative subtype of posttraumatic stress disorder (PTSD) was incorporated into the diagnostic criteria for PTSD in , Fifth Edition (DSM-5). The subtype requires the presence of persistent or recurrent depersonalization or derealization; however, several authors have suggested that a broader array of dissociative symptoms could be included in the criteria. The objective of the present study was to gather data on a wide range of dissociative symptoms in a sample of highly traumatized individuals.

Previous studies have demonstrated the high prevalence of dissociative symptoms and their association with considerable healthcare costs. However, there is a lack of studies that describe whether dissociative symptoms persist and lead to other clinical outcomes over time in the community. This study investigated the persistence, predictors, and consequences of dissociative symptoms in the community.

The impacts of adverse childhood experiences (ACEs) have been well documented. One possible consequence of ACEs is dissociation, which is a major feature of post-traumatic psychopathology and is also associated with considerable impairment and health care costs. Although ACEs are known to be associated with both psychoform and somatoform dissociation, much less is known about the mechanisms behind this relationship.

Background: Previous studies have indicated that borderline personality disorder (BPD) is closely associated with trauma and dissociation. Nevertheless, BPD is a heterogeneous condition, and not all people with BPD have severe dissociation. This study examined whether the relationship of BPD features with trauma and dissociation would remain significant after controlling for some general non-specific mental health distress.

The author replies to a critique of his paper about false memories in an effort to clarify issues on which there is disagreement. A key point made is that the validity of dissociation as a phenomenon, that is, as reported symptoms, does not depend on theories about the mechanisms of dissociation. There are no proven mechanisms for any mental health symptoms or DSM-5 diagnoses including anxiety, depression, psychosis and substance use disorders.

Background: Trauma has been increasingly linked to depression. Previous studies have suggested that comorbid post-traumatic stress disorder (PTSD) may be associated with poor outcomes in depression treatment. However, the prevalence and correlates of ICD-11 PTSD and complex PTSD (CPTSD) in people with depression remain unclear.

Complex post-traumatic stress disorder (CPTSD) has recently been recognized as an official psychiatric diagnosis in ICD-11, after years of research and advocacy in the field. It has been suggested that dissociative symptoms are a major feature of CPTSD. This scoping review aimed to summarize the existing knowledge base on the relationship between dissociation and CPTSD, and to identify relevant research gaps.

Pathological dissociation is a common trauma-related condition and is associated with considerable health and social care needs. People with pathological dissociation typically require psychosocial interventions, but there are many challenges in providing such interventions for this vulnerable population. An important question that remains unexplored is whether web-based interventions are acceptable and beneficial for people with pathological dissociation.

Article Synopsis
  • - The paper explores the connection between schizophrenia spectrum disorders (SSDs) and pathological dissociation, highlighting that a significant number of patients with SSDs may also experience dissociative symptoms.
  • - In a study of 100 hospitalized SSD patients in Taiwan, over 60% displayed signs of pathological dissociation, with 54% meeting criteria for a dissociative disorder, including three individuals diagnosed with dissociative identity disorder.
  • - Findings suggest that individuals with dissociative disorders often report more severe trauma and psychotic symptoms, indicating the need for clinical assessments to include dissociative measures for better early identification and treatment.

Background: To improve the outcomes of depression treatment, personalized treatments that take individual needs into account are recommended. Recent research suggests that a subgroup of depressed people who suffer from co-occurring dissociation may be more likely to have encountered traumatic or stressful experiences and they may also have more psychosocial intervention needs.

Methods: This study examined the prevalence and correlates of dissociative symptoms in an online convenience sample of people (N = 410) from 18 different countries/regions who reported clinically significant levels of depressive symptoms (indicated by Patient Health Questionnaire-9 score ≥10).

Background: Childhood adversities have been increasingly recognized as a significant risk factor for depression. However, the underlying mediating mechanism between childhood adversities and depression requires further investigation. The literature shows that childhood adversities are also closely associated with post-traumatic stress disorder (PTSD) symptoms and that PTSD symptoms can predict depressive symptoms.

Betrayal trauma theory proposes that betrayal and non-betrayal traumas are different in terms of their nature and impacts. The theory predicts that dissociation is more strongly related to betrayal than to non-betrayal trauma, however there is a lack of cross-cultural evaluation of the theory. One competing theory is the socio-cognitive model, which proposes that dissociative amnesia (DA) and identity dissociation (ID) are the results of social influence and are not trauma-related conditions.

Objective: Studies on maladaptive daydreaming have shown that it has a number of comorbidities including dissociative disorders, yet no studies have examined the reciprocal relationship. The aim of this study was to determine the frequency of maladaptive daydreaming in a sample of psychiatric inpatients with high levels of dissociation.

Methods: The Dissociative Experiences Scale (DES), Self-Report Dissociative Disorders Interview Schedule, Maladaptive Daydreaming Scale-16 (MDS-16), Structured Clinical Interview for Maladaptive Daydreaming, and the Obsessive Compulsive Inventory were administered to a sample of 100 inpatients in a psychiatric hospital program specializing in dissociative disorders.

Auditory hallucinations are widely regarded as symptoms of brain disease treated with medications. In an alternative paradigm, voices are understood as trauma-driven dissociated, disowned, or disavowed aspects of self; the goal is not to suppress them but to integrate them during psychotherapy. Auditory hallucinations are common in dissociative identity disorder, borderline personality disorder, and complex posttraumatic stress disorder and are not specific to psychosis.
