Schizophrenia and dissociation: Its relation with severity, self-esteem and awareness of illness

Dissociation and misdiagnosis of schizophrenia in populations experiencing chronic discrimination and social defeat

As recently as the late 20th century, Schizophrenia, a category of mental illness with widely varying phenotypic symptoms, was believed by psychobiologists to be a genetically based disorder in which the environment played a limited etiological role. Yet a growing body of evidence indicates a strong correlation between schizophrenia and environmental factors. This theoretical paper explores the relationship between highly elevated rates of schizophrenia in some low-income minority communities worldwide and trauma-related dissociative symptoms that often mimic schizophrenia. Elevated rates of schizophrenia in racially and ethnically isolated, inner-city Black populations are well documented. This paper contains evidence proposing that this amplification in the rate of schizophrenia is mediated by childhood trauma, disorganized attachment, and social defeat. Further, evidence demonstrating how these three variables combine in early childhood to incubate dissociative disorders will also be conveyed. The misdiagnosis of dissociative disorders as schizophrenia is theorized to partially mediate the increased rate of schizophrenia in communities that experience high levels of racial/ethnic discrimination. It is argued that this misdiagnosis is often attributable to cultural misunderstanding and/or a lack of knowledge about dissociative disorders.

Dissociation and recovery in psychosis - an overview of the literature

Background

The relationship between dissociation and recovery from psychosis is a new topic, which could attract the interest of the researchers in the field of dissociation due to its relevance to their daily clinical practice. This review brings together a diversity of international research and theoretical views on the phenomenology of dissociation, psychosis and recovery and provides a synthesis by narrative and tabulation of the existing knowledge related to these concepts.

Aims

The objective was to make a synthesis by narrative and tabulation about what is known on the topic.

Methods

The systematic search was conducted according to the PRISMA-statement in the databases Medline, PsycInfo, PubMed and Google Scholar. 2110 articles were selected according to the inclusion and exclusion criteria detailed in the methods, and 19 records were included in the review.

Outcomes

None of the included publications put together, in the same conceptualisation or hypothesis, dissociation and the recovery from an episode of psychosis, therefore this matter remains unstudied at this time.

Conclusion

The process of reviewing the existing scientific literature in the field of dissociation and recovery from psychosis has been very useful for charting the direction that future research will take.

Beyond One's Attitude Toward the Self: The Role of Social Anxiety in Self-Stigma Among Individuals With Schizophrenia

ABSTRACT

Self-stigma is associated with a variety of negative self-perceptions among people coping with schizophrenia, as well as with different aspects of social behaviors. We explored the associations between self-compassion, self-esteem, social anxiety, and self-stigma among people coping with schizophrenia. The baseline data of 56 adults with schizophrenia who were enrolled in a Metacognitive Reflection and Insight Therapy trial were used. Participants filled out self-report questionnaires measuring self-compassion, self-esteem, social anxiety, and self-stigma. Self-esteem and self-compassion were negatively correlated with self-stigma and social anxiety. Self-compassion was not found to contribute beyond self-esteem to the prediction of self-stigma. Importantly, self-esteem and social anxiety were found to mediate the effects of self-compassion on self-stigma. Thus, it seems that social variables, in addition to self-variables, may lead to the formation of self-stigma among people with schizophrenia. Therefore, alongside addressing self-esteem and self-compassion, integrating therapeutic elements related to coping with social anxiety into interventions would seem to be an important factor in reducing self-stigma among people with serious mental illness.

Alexithymia and post-traumatic stress disorder symptoms in Chinese undergraduate students during the COVID-19 national lockdown: The mediating role of sleep problems and the moderating role of self-esteem

OBJECTIVE

This study examined whether sleep disturbance was a mediator between alexithymic traits and post-traumatic stress disorder (PTSD) COVID-19 pandemic-related stress symptoms, and explored whether self-esteem moderated the alexithymic contribution to poor sleep and PTSD symptoms.

METHOD

A representative sample of young adults (N = 2,485) from six universities in Southwest China completed online self-report surveys on alexithymia, sleep, PTSD, self-esteem, sociodemographic information, and health-related behaviors.

RESULTS

High alexithymic young adults were found to be more likely to have higher sleep problems and higher PTSD symptoms. The moderated mediation model showed that sleep problems mediated the associations between alexithymia and PTSD symptoms. Alexithymic people with lower self-esteem were more likely to have elevated PTSD symptoms and sleep problems than those with higher self-esteem.

CONCLUSION

Targeted psychological interventions for young people who have difficulty expressing and identifying emotions are recommended as these could assist in reducing their post-traumatic psychophysical and psychological problems. Improving self-esteem could also offer some protection for trauma-exposed individuals.

Dissociative Model in Patients With Resistant Schizophrenia

BACKGROUND

Schizophrenia is a severe mental illness in which, despite the growing number of antipsychotics from 30 to 50% of patients remain resistant to treatment. Many resistance factors have been identified. Dissociation as a clinical phenomenon is associated with a loss of integrity between memories and perceptions of reality. Dissociative symptoms have also been found in patients with schizophrenia of varying severity. The established dispersion of the degree of dissociation in patients with schizophrenia gave us reason to look for the connection between the degree of dissociation and resistance to therapy.

METHODS

The type of study is correlation analysis. 106 patients with schizophrenia were evaluated. Of these, 45 with resistant schizophrenia and 60 with clinical remission. The Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) scales were used to assess clinical symptoms. The assessment of dissociative symptoms was made with the scale for dissociative experiences (DES). Statistical methods were used to analyze the differences in results between the two groups of patients.

RESULTS

Patients with resistant schizophrenia have a higher level of dissociation than patients in remission. This difference is significant and demonstrative with more than twice the level of dissociation in patients with resistant schizophrenia.The level of dissociation measured in patients with resistant schizophrenia is as high as the points on the DES in dissociative personality disorder.

CONCLUSION

Patients with resistant schizophrenia have a much higher level of dissociation than patients in clinical remission. The established difference between the two groups support to assume that resistance to the administered antipsychotics is associated with the presence of high dissociation in the group of resistant patients. These results give us explanation to think about therapeutic options outside the field of antipsychotic drugs as well as to consider different strategies earlier in the diagnostic process.

Development and initial evaluation of a measure of positive beliefs about dissociative experiences

Theoretical models and qualitative research suggest that dissociation can be functional in some circumstances, despite being a cause of concern for many. This is the first study that evaluates a novel questionnaire on positive appraisals of dissociation (the Positive Beliefs about Dissociation Questionnaire; PBD-Q), and its link with dissociation frequency and related distress. Development of items was based on lived experience expertise within the research team and qualitative findings. Items were refined through cognitive interviewing with people with lived experience of dissociation prior to deployment using an online survey. A sample of 228 participants scoring >10 on the Dissociative Experiences Scale (DES-II) completed a battery of measures comprising the PBD-Q and a previously developed measure of negative beliefs of dissociation. Exploratory factor analysis revealed three factors: positive beliefs about emotion management, positive beliefs about self-expression, and positive beliefs about maintaining social image. Within this particular sample the PBD-Q showed excellent internal consistency, face validity, convergent validity, and test-retest reliability. Higher scores on the PBD-Q were significantly related to higher frequencies of dissociative experiences as well as dissociation-related distress. The factor structure remained stable when the analyses were restricted to individuals scoring >30 on the DES-II. In conclusion, our findings indicate that positive beliefs about dissociation can be reliably and validly measured in adults who experience levels of dissociation that are higher than the general population. These beliefs could be involved in the maintenance of dissociation and represent promising targets for future research, clinical assessment, and treatment.

Childhhood Trauma in Schizophrenia Spectrum Disorders: Dissociative, Psychotic Symptoms, and Suicide Behavior

Current evidence suggests a high prevalence of childhood trauma (CT) among adult patients diagnosed with schizophrenia spectrum disorders. Exposure to CT might lead to clinical differences eventually observed in these patients. We present a cross-sectional study with 54 patients with schizophrenia spectrum disorder (schizophrenia and schizoaffective disorder). We obtained sociodemographic data, as well as data on CT, dissociation, suicide history, and intensity of positive and negative psychotic symptoms. More than 75% of the patients reported a history of CT. We observed a link between CT and suicidal behavior. Patients showed high rates of dissociation. Dissociative experiences were related to CT, both in terms of intensity of trauma and number of traumas experienced. All CT forms except emotional neglect showed direct correlations with dissociative experiences. We found no correlation between intensity of CT and intensity of positive psychotic symptoms, yet we observed a moderate inverse correlation with negative psychotic symptoms.

The Relationship Between Dissociation and Symptoms of Psychosis: A Meta-analysis

Evidence suggests that dissociation is associated with psychotic experiences, particularly hallucinations, but also other symptoms. However, until now, symptom-specific relationships with dissociation have not been comprehensively synthesized. This is the first prospectively registered (CRD42017058214) meta-analysis to quantify the magnitude of association between dissociative experiences and all symptoms of psychosis. MEDLINE, PsycINFO, PubMed, and Scopus databases were searched using exhaustive terms denoting dissociation and psychotic symptoms. We included both nonclinical (58 studies; 16 557 participants) and clinical (46 studies; 3879 patient participants) samples and evaluated study quality. Ninety-three eligible articles considering 20 436 participants were retained for analysis. There was a robust association between dissociation and clinical and nonclinical positive psychotic symptoms (r = .437; 95%CI: .386 -.486), with the observed effect larger in nonclinical studies. Symptom-specific associations were also evident across clinical and nonclinical studies, and included significant summary effects for hallucinations (r = .461; 95%CI: .386 -.531), delusions (r = .418; 95%CI: .370 -.464), paranoia (r = .447; 95%CI: .393 -.499), and disorganization (r = .346; 95%CI: .249 -.436). Associations with negative symptoms were small and, in some cases, not significant. Overall, these findings confirm that dissociative phenomena are not only robustly related to hallucinations but also to multiple positive symptoms, and less robustly related to negative symptoms. Our findings are consistent with proposals that suggest certain psychotic symptoms might be better conceptualized as dissociative in nature and support the development of interventions targeting dissociation in formulating and treating psychotic experiences.

The association between insight and depressive symptoms in schizophrenia: Undirected and Bayesian network analyses

Background.

Greater levels of insight may be linked with depressive symptoms among patients with schizophrenia, however, it would be useful to characterize this association at symptom-level, in order to inform research on interventions.

Methods.

Data on depressive symptoms (Calgary Depression Scale for Schizophrenia) and insight (G12 item from the Positive and Negative Syndrome Scale) were obtained from 921 community-dwelling, clinically-stable individuals with a DSM-IV diagnosis of schizophrenia, recruited in a nationwide multicenter study. Network analysis was used to explore the most relevant connections between insight and depressive symptoms, including potential confounders in the model (neurocognitive and social-cognitive functioning, positive, negative and disorganization symptoms, extrapyramidal symptoms, hostility, internalized stigma, and perceived discrimination). Bayesian network analysis was used to estimate a directed acyclic graph (DAG) while investigating the most likely direction of the putative causal association between insight and depression.

Results.

After adjusting for confounders, better levels of insight were associated with greater self-depreciation, pathological guilt, morning depression and suicidal ideation. No difference in global network structure was detected for socioeconomic status, service engagement or illness severity. The DAG confirmed the presence of an association between greater insight and self-depreciation, suggesting the more probable causal direction was from insight to depressive symptoms.

Conclusions.

In schizophrenia, better levels of insight may cause self-depreciation and, possibly, other depressive symptoms. Person-centered and narrative psychotherapeutic approaches may be particularly fit to improve patient insight without dampening self-esteem.

Better insight seems associated with depressive symptoms in schizophrenia.

Network analyses were used to explore this association in a large sample.

Insight was associated with self-depreciation, guilt, and suicidal ideation.

Although cross-sectional, data suggest causal direction from insight to depression.

Adolescent suicide risk and experiences of dissociation in daily life

Dissociation is associated with risk for suicide in adults, but this link is not well studied in adolescents, in spite of their marked suicide risk. This study assessed adolescents' dissociative experiences in daily life and evaluated the association between dissociative experiences and suicide risk, including the independence of this relationship from related affective and clinical states and demographic characteristics. Clinically referred early adolescents (N = 162; aged 11-13) were assessed via multi-informant clinical interview, questionnaires, and 4-day ecological momentary assessment protocol. Adolescents were classified as being at elevated suicide risk using multi-informant, multi-method reports of suicide risk behavior and/or at elevated proximal risk using the 4-day EMA only. Suicide risk was associated with daily dissociative experiences, and this relationship was independent of daily negative and positive affect and co-occurring borderline personality symptoms. Gender differences emerged, such that the relationship between daily dissociative experiences and suicide risk was only significant in adolescent girls. Overall, findings suggest dissociation may be independently relevant to adolescent suicide risk, above and beyond effects of psychopathology and affective disturbance, and especially in girls. Daily dissociative experiences may help understand and detect suicide risk among early adolescents and warrant further research.
