Trauma, Emotional Regulation, and Coping Styles in Individuals with and without Probable Dissociative Disorders in Hong Kong.

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. This study aimed to investigate the relationship between trauma, emotional regulation, coping, and dissociation. We analyzed baseline data from a randomized controlled trial (N = 101). Participants with dissociative symptoms in Hong Kong completed self-report assessments. Structured interviews were also conducted subsequently. Participants with probable DDs reported more traumatic events (p = .009 to .017) and exhibited significantly higher levels of dysfunctional coping (p < .001) compared to those who reported dissociative symptoms but did not have a DD. Dissociative symptoms were more strongly associated with betrayal trauma than with non-betrayal trauma. Among different emotion regulation and coping strategies, dysfunctional coping was the only significant factor associated with dissociative symptoms (ß = .309, p = .003). Dysfunctional coping was a statistically significant mediator that may explain the relationship between betrayal trauma and dissociative symptoms. Although other mediation paths are also possible and further longitudinal studies are required, our findings highlight the strong link between dysfunctional coping and dissociative symptoms and suggest that coping skills training should be incorporated into interventions for betrayal trauma survivors with dissociative symptoms. Additionally, this study provides evidence for the cross-cultural validity of the betrayal trauma theory. Further studies, however, are required.

Reliability and Mental Health Correlates of a Single-Item Measure of Self-Rated Mental Health (SRMH) in the Chinese Context.

The use of single-item measures of self-rated mental health (SRMH) has been increasingly valued in epidemiologic research. However, little is known about the reliability and mental health correlates of SRMH in Chinese populations. This study examined the reliability and mental health correlates of SRMH in three Chinese samples. We analyzed data collected from two convenience samples of Chinese adults from Hong Kong and/or Taiwan (Sample 1: N = 205; Sample 2: N = 377), and a random sample of Taiwan psychiatric inpatients (Sample 3: N = 100). Our results showed that the single-item measure of SRMH had moderate to good test-retest reliability (intraclass correlation [ICC] = 0.75) in Sample 1 and acceptable reliability between the self-report and interviewer-administered versions (ICC = 0.58) in Sample 3. It had a high positive correlation with self-esteem and a moderately high negative correlation with depression. It also had a consistently negative correlation with borderline personality disorder symptoms and post-traumatic stress disorder symptoms. The SRMH score was also associated with psychiatric service usage. These findings contribute to the body of knowledge regarding the use of a single-item measure of SRMH to assess overall self-perceived mental health in Chinese communities.

COULD FAMILY WELL-BEING MODERATE THE RELATIONSHIP BETWEEN ADVERSE CHILDHOOD EXPERIENCES AND SOMATOFORM DISSOCIATION? A PRELIMINARY INVESTIGATION.

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. Little is known about whether social and interpersonal factors such as family environments would moderate the relationship between ACEs and somatoform dissociation. This paper discusses the importance of having a positive and healthy family environment in trauma recovery. We then report the findings of a preliminary study in which we examined whether the association between ACEs and somatoform dissociation would be moderated by family well-being in a convenience sample of Hong Kong adults (N = 359). The number of ACEs was positively associated with somatoform dissociative symptoms, but this association was moderated by the level of family well-being. The number of ACEs was associated with somatoform dissociation only when the family well-being scores were low. These moderating effects were medium. The findings point to the potential importance of using family education and intervention programs to prevent and treat trauma-related dissociative symptoms, but further investigation is needed.

The symptom criteria for the dissociative subtype of posttraumatic stress disorder.

OBJECTIVE: The dissociative subtype of posttraumatic stress disorder (PTSD) was incorporated into the diagnostic criteria for PTSD in Diagnostic and Statisical Manual of Mental Disorders, 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. METHOD: The authors administered a set of measures to 62 inpatients in a private psychiatric inpatient program specializing in PTSD and dissociative disorders. RESULTS: Almost every participant met International Classification of Diseases, 11th Edition criteria for complex PTSD, DSM-5 criteria for the dissociative subtype of PTSD, and DSM-5 criteria for dissociative identity disorder or other specified dissociative disorder; these four diagnoses seem to identify largely the same patients and may not be separate disorders. CONCLUSIONS: A broad range of dissociative symptoms was endorsed on the Dissociative Experiences Scale and the Dissociative Disorders Interview Schedule. The results support a recommendation that a broad array of symptoms be included in the criteria for the dissociative subtype of PTSD in future editions of the Diagnostic and Statistical Manual of Mental Disorders.

Dissociative symptoms among community health service users in Hong Kong: a longitudinal study of clinical course and consequences.

Background: 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.Objectives: This study investigated the persistence, predictors, and consequences of dissociative symptoms in the community.Methods: We analyzed longitudinal data in a sample of community health service users in Hong Kong (N = 173).Results: A relatively high proportion (63.6%) of participants with baseline dissociative symptoms continued to exhibit dissociative symptoms after approximately 9 months. Baseline non-betrayal trauma predicted subsequent dissociative symptoms (ß = .141, p = .024). Participants with baseline dissociative symptoms were more likely to have received subsequent emergency mental health services (9.1% vs 0.7%, p = .005). Baseline dissociative symptoms significantly predicted subsequent post-traumatic symptoms (ß = .165 to .191, p < .05) and difficulty in social and occupational participation (ß = -.152 to -.182, p < .05) even after controlling for baseline scores, trauma exposure, and use of professional support. The predictive role of dissociative symptoms on subsequent disturbances in self-organization symptoms and social participation difficulty remained significant after applying the Bonferroni correction.Conclusions: This is one of the very few studies showing that dissociative symptoms are persistent to a certain degree and could predict other symptoms and subsequent impairments even in community settings. Factors that affect the trajectory of dissociative symptoms should be further investigated. Regular screening for dissociative symptoms is recommended. Considering its prevalence, persistence, and clinical and social consequences, dissociation should be given greater public health attention.

Borderline personality disorder features and their relationship with trauma and dissociation in a sample of community health service users.

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. We also made the first attempt to explore which specific BPD features would be particularly associated with dissociation. METHODS: We analyzed survey data from a sample of community health service users in Hong Kong (N = 376). Hierarchical multiple regression and data-driven network analysis were used. RESULTS: The lifetime prevalence of DSM-5 BPD was 16.0% in our sample. Of participants who met criteria for BPD, 43.3% scored above cutoff on the dissociation measures, thus possibly having clinically significant dissociative symptoms. BPD features were associated with adulthood trauma and psychoform dissociation even after controlling for age, depression and self-esteem. Network analysis showed that some BPD features - including impulsivity, identity disturbance and suicidal/self-mutilation behaviors - were particularly associated with dissociation; other BPD features such as interpersonal-related problems had relatively weak to no connection with dissociation. CONCLUSIONS: Our results suggested that some particular BPD features might be dissociative in nature, although further longitudinal research is required. We argue that a trauma-informed perspective should be employed when working with clients presenting with BPD features despite these features being commonly stigmatized. Further research on the intervention needs of the people with BPD who suffer from high levels of dissociation is required.

The False Memory Debate A Reply to Otgaar.

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.

A Cross-Cultural Investigation of the Association between Betrayal Trauma and Dissociative Features.

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. This study aimed to test the hypotheses based on betrayal trauma theory and investigated the relationship between trauma, dissociation and other mental health problems in two culturally different convenience samples of people seeking web-based educational interventions for dissociation (N = 83 English speakers and N = 82 Chinese speakers). Compared with childhood non-betrayal trauma, childhood betrayal trauma had a statistically stronger relationship with dissociation and borderline personality disorder (BPD) symptoms in both samples. DA and ID symptoms were cross-culturally associated with childhood betrayal trauma after controlling for other variables (including sample membership, age, depression levels, medication treatment and non-betrayal trauma). Participants with DA/ID symptoms reported significantly more trauma-related symptoms in both samples. The findings supported the cross-cultural application of the betrayal trauma theory for dissociative features and BPD symptoms. Implications for research and practice (e.g., child protection, assessment for survivors of childhood betrayal trauma) are highlighted.

Prevalence and sociocultural correlates of post-traumatic stress disorder and complex PTSD among Chinese community health service users in Hong Kong.

OBJECTIVES: Complex post-traumatic stress disorder (CPTSD) is a newly recognized trauma disorder in ICD-11. Little is known about the prevalence and correlates of CPTSD in primary care settings. Its cultural aspects also remained minimally explored. This study investigated the prevalence and sociocultural correlates of PTSD and complex PTSD among Chinese community health service users in Hong Kong. METHODS: This study investigated ICD-11 PTSD and CPTSD in a sample of adults (N = 376) who had recently received services from Registered Chinese Medicine Practitioners in Hong Kong. Traditional Chinese medicine service is part of primary care services in Chinese societies. Participants completed self-report measures of CPTSD, trauma exposure, perceived family support, perceived caregiver's Chinese traditionality/modernity, participation (social activities and occupational productivity), depression and pain. RESULTS: The past-month prevalence of ICD-11 PTSD and CPTSD was 5.6% and 18.4%, respectively, in our sample. Chi-square tests and one-way ANOVAs revealed that participants with CPTSD were younger and reported more trauma, lower family support, lower levels of social participation and productivity, more depressive symptoms and pain, and more social welfare and mental health service usages than those without PTSD. We found that perceived caregiver's Chinese modernity (e.g. egalitarianism) was negatively correlated with CPTSD symptoms. Apart from age, non-betrayal trauma had the strongest association with classical PTSD symptoms, while betrayal trauma and perceived family support had the strongest association with disturbances in self-organization symptoms. CONCLUSION: This study provides the first data regarding the prevalence and correlates of ICD-11 PTSD and CPTSD among community health service users in Hong Kong. PTSD and CPTSD are common but often unrecognized mental health problems which are associated with more impairments and more service needs.

The Relationship Between Dissociation and Complex Post-Traumatic Stress Disorder: A Scoping Review.

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. We searched the two largest and most widely used academic databases (i.e., the Web of Science and Scopus databases) and the ProQuest database and identified original studies published in English relevant to our research questions, namely: (1) Would CPTSD be associated with dissociative symptoms? 2) How common are dissociative symptoms among people with CPTSD? (3) What are the correlates of dissociative symptoms among people with CPTSD? In all, 26 studies were included. We found 10 studies which reported that people with CPTSD scored significantly higher on a dissociation measure than those without CPTSD, and 11 studies reported a positive correlation between CPTSD symptoms and psychoform/somatoform dissociation scores. While very few studies reported the prevalence and correlates of dissociative symptoms among people with CPTSD, there may be a considerable subgroup of people with CPTSD who have clinically significant levels of dissociative symptoms (e.g., 28.6-76.9%). Dissociation may also be associated with other comorbidities (e.g., DSM-IV Axis II features, shame, somatic symptoms) in people with CPTSD. We recommend that more studies are needed to investigate the prevalence of dissociative symptoms among people with CPTSD and examine how these symptoms are associated with other comorbid conditions and clinical needs in this vulnerable group.

The Acceptability and Potential Benefits of a Web-Based Psychoeducation Program for People with Pathological Dissociation: A Pilot Evaluation Study.

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. This paper reports the findings of a pilot evaluation study of a web-based psychoeducation program for people with pathological dissociation. A total of 80 participants were included. The preliminary findings revealed that: most participants were satisfied with the web-based program (e.g., most participants agreed that the program helped them understand [94.1%] and manage [66.7%] their mental health conditions and remain hopeful for recovery [78.4%]); and participants had improvements in symptom management (large effect; partial eta squared = .143) and self-esteem (medium-to-large effect; partial eta squared = .111) after the program. However, no improvements in clinical symptoms were observed on measures of post-traumatic or dissociative symptoms. The dropout rate at posttest was 36.3%. This is one of the first studies that evaluated web-based interventions for people with pathological dissociation. Although the web-based program is well-accepted by the participants and might be associated with some potential benefits, the limitations of this pilot study should be acknowledged. Implications are discussed in terms of the directions for future developments of the program and the needs for further evaluation.

Investigating post-traumatic stress disorder (PTSD) and complex PTSD among people with self-reported depressive symptoms.

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. Methods: This study examined the prevalence and correlates of ICD-11 PTSD and CPTSD in an online convenience sample of 410 adults from 18 different countries/regions who reported clinically significant levels of depressive symptoms (indicated by a Patient Health Questionnaire-9 score ≥10). Results: According to the International Trauma Questionnaire results, 62.68% of participants met the ICD-11 criteria for PTSD/CPTSD (5.6% PTSD, 57.1% CPTSD). Participants with CPTSD reported more types of trauma and higher levels of interpersonal stress than those without PTSD. Participants with CPTSD also reported higher levels of mental health problems, including depressive, dissociative and psychotic symptoms, than those without PTSD. Only disturbances in self-organization (DSO) symptoms but not classical PTSD symptoms had a significant relationship with depressive symptoms, when other major variables (including trauma, interpersonal stress, and comorbid psychotic and dissociative symptoms) were controlled for. Conclusions: Trauma-related symptoms should be regularly screened for in clients who report depressive symptoms. Depressed clients who have comorbid trauma disorders have more trauma and interpersonal stress and exhibit more severe mental health problems. They may require specific trauma-focused interventions in addition to standard depression treatments.

Prevalence and correlates of dissociative symptoms among people with depression.

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). RESULTS: Over 60% of participants exhibited clinically significant levels of dissociative symptoms (indicated by a Multiscale Dissociation Inventory total score >66). Compared with those with low levels of dissociative symptoms, participants with high levels of dissociative symptoms reported more traumas, interpersonal stress, depression and trauma-related symptoms. Emotional constriction in particular had a weak but significant negative correlation with the level of perceived medication benefits. LIMITATIONS: The use of an online convenience sample could limit the generalizability of our findings. Our cross-sectional data could not demonstrate causal relationships between the study variables. CONCLUSIONS: The findings highlight a need for complex health interventions for depressed people with co-occurring dissociative symptoms, focusing not only on depressive symptoms but also addressing trauma and dissociation-related symptoms.

Trauma and dissociation among inpatients diagnosed with schizophrenia spectrum disorders in Taiwan.

Background: The overlapping symptoms of schizophrenia and dissociation have been increasingly recognized. This paper explains why it is reasonable to expect that there would be a substantial subgroup of patients diagnosed with schizophrenia spectrum disorders (SSDs) who suffer from pathological dissociation. Objective: As little is known about the prevalence of dissociative disorders and symptoms among patients with SSDs, we investigated the prevalence of dissociative disorders and symptoms among patients with SSDs. Method: We used both self-report measures and structured interviews to examine dissociative disorders and symptoms in a randomly recruited sample of inpatients with a clinical diagnosis of SSDs in Taiwan (N = 100). Results: Over 60% of participants exhibited pathological dissociation, and 54% had a dissociative disorder according to structured interview data; three participants met the DSM-5 diagnostic criteria for dissociative identity disorder. The concurrent validity of pathological dissociation in this sample was similar to that of depression among patients with schizophrenia reported in the literature. Participants with a dissociative disorder were more likely to report high-betrayal traumas and meet DSM-5 criteria for post-traumatic stress disorder; they also reported more psychotic symptoms than those without a dissociative disorder. Conclusions: This was one of very few studies that used structured interviews to examine pathological dissociation in patients with SSDs. The results indicate that pathological dissociation in SSDs is not uncommon. Clinical assessment should include measures of dissociation to facilitate early identification.

Antecedentes: Los síntomas superpuestos de Esquizofrenia y Disociación han sido cada vez más reconocidos. Este artículo explica por qué es razonable esperar que estos sean un subgrupo sustancial de pacientes diagnosticados con trastornos del espectro de la esquizofrenia (SSDs por sus siglas en ingles) que sufren de disociación patológica.Objetivos: Como se conoce poco sobre la prevalencia de los trastornos y síntomas disociativos entre pacientes con SSDs, nosotros investigamos la prevalencia de trastornos y síntomas disociativos entre los pacientes con SSDs.Método: Utilizamos medidas de autoinforme y entrevistas estructuradas para examinar los trastornos y síntomas disociativos, en una muestra reclutada al azar de pacientes hospitalizados con diagnóstico clínico de SSDs en Taiwán (N = 100).Resultados: Más del 60% de los participantes exhibieron disociación patológica, y el 54% tuvo un trastorno disociativo según datos de entrevistas estructuradas; tres participantes cumplieron con los Criterios diagnósticos del DSM-5 para trastorno de identidad disociativo. La validez concurrente de la disociación patológica en esta muestra, fue similar a la de depresión entre los pacientes con esquizofrenia reportada en la literatura.Los participantes con trastorno disociativo tuvieron más probabilidad de informar traumas de alta-traición y cumplían los criterios del DSM-5 para trastorno de estrés postraumático; también informaron más síntomas psicóticos que aquellos sin un trastorno disociativo.Conclusiones: Este fue uno de los pocos estudios que utilizó entrevistas estructuradas para examinar disociación patológica en pacientes con SSDs. Los resultados indican que la disociación patológica en SSDs no es infrecuente. La evaluación clínica debe incluir medidas de disociación para facilitar la identificación temprana.

The mediating role of post-traumatic stress disorder symptoms in the relationship between childhood adversities and depressive symptoms in two samples.

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. It remains unexplored whether PTSD symptoms can act as a mediator between childhood adversities and depression. OBJECTIVES: The primary goal of this study was to examine whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms. PARTICIPANTS AND SETTING: We examined in a convenience sample of Hong Kong adults aged 18 or above (N = 418) whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms. We then examined and compared the results with those in another convenience sample of Chinese-speaking young adults (mainly from Taiwan and Hong Kong) aged between 18 and 24 (N = 205). Participants in both samples completed online surveys that included measures of childhood adversities, PTSD symptoms and depressive symptoms. RESULTS: Childhood adversities were significantly associated with depressive symptoms; and this relationship was mediated by PTSD symptoms in both samples. CONCLUSION: This study is one of very few studies demonstrating that PTSD symptoms mediate the relationship between childhood adversities and depressive symptoms. Our findings suggest that addressing unresolved PTSD symptoms for adults with childhood adversities may help in preventing or treating depressive symptoms. Therefore, PTSD symptoms should be taken into account in the prevention and management of depression.

Reversal of Amnesia for Trauma in a Sample of Psychiatric Inpatients with Dissociative Identity Disorder and Dissociative Disorder Not Otherwise Specified.

The authors interviewed 118 highly dissociative inpatients in a Trauma Program with the Dissociative Disorders Interview Schedule, the Dissociative Experiences Scale and the Adverse Childhood Experiences questionnaire; of the 118 participants 42 met DSM-5 criteria for dissociative identity disorder and 52 for other specified dissociative disorder. The average score on the Dissociative Experiences Scale in the sample of 118 participants was 44.7. The authors also conducted semi-structured interviews inquiring about the circumstances and triggers for reversal of amnesia for childhood trauma in the participants. Only a small minority of the reversal of amnesia took place in therapy sessions, and 24 different triggers for remembering were described. Childhood sexual abuse was by far the most common type of trauma for which amnesia was reversed. The findings are inconsistent with the view that amnesia for childhood sexual abuse is reversed primarily during psychotherapy.

The Dissociative Taxon and Dissociative Identity Disorder.

A total of 491 participants from four previous studies, 443 of whom were diagnosed with dissociative identity disorder (DID) on the Dissociative Disorders Interview Schedule, completed the Dissociative Experiences Scale (DES). Their results were analyzed to determine how many were in the dissociative taxon (DES-T) on the DES. Of the 443 individuals with DID, 419 (94.6%) were in the taxon, 13 (2.9%) were out of the taxon and 11 (2.5%) were indeterminate. The DES-T is therefore very effective at identifying people with DID as being in the dissociative taxon, although it does have a false negative rate of 5.4%. Out of 48 people with no dissociative disorder on the Dissociative Disorders Interview Schedule, the DES-T identified 26 (54.2%) as being in the taxon and 22 (45.8%) as being out of the taxon with no indeterminate cases. The clinical diagnoses of these 48 individuals are unknown: all were inpatients in the same Trauma Program. Thus, the sensitivity of the DES-T for confirming that individuals with DID are in the dissociative taxon was 94.6% and the specificity of the DES-T for confirming that individuals with no dissociative disorder are not in the dissociative taxon was 45.8%. It is possible that the DES-T yields false positives for taxon membership; this possibility should be investigated in future research.

Clinical Features of a Chinese Sample with Self-Reported Symptoms of Pathological Dissociation.

People with pathological dissociation should receive proper clinical attention and timely support. Recent studies have shown that pathological dissociation is common in the Chinese context. However, little is known about the clinical features of Chinese people with pathological dissociation. This paper reports the first data regarding trauma histories, mental health symptoms, clinical diagnoses, service usages, stigma and psychosocial needs in a convenience sample of Chinese people who screened positive for pathological dissociation on a self-report measure (N = 72). This sample was characterized by a history of trauma and high levels of trauma-related symptoms and depression. Medication treatments were the most common interventions for them; many participants did not receive psychotherapy. We found no clinical differences between participants who had and had not received psychotherapy for post-traumatic/dissociative symptoms. This implies that many participants did not have the chance of receiving specific psychotherapy even though their trauma histories and clinical symptoms were as severe as those who were receiving specific psychotherapy. Stigma and unmet psychosocial needs were common in this sample and should receive more attention in the field. Implications for research and practice are highlighted. More dissociation-informed services are required for Chinese-speaking populations.

Voices: Are They Dissociative or Psychotic?

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. The features that differentiate psychotic from dissociative voices include the qualities of the voices themselves, as well as other symptoms: for example, compared with dissociative voices, psychotic voices are accompanied by less sociability, more formal thought disorder, more negative symptoms including blunted affect, and more delusions. The author proposes that the psychotherapy of dissociative voices can be indicated trans-diagnostically, including in a subgroup of individuals with diagnoses of schizophrenia. Psychotherapeutic strategies are illustrated with a case example.
