Early trauma, attachment experiences and comorbidities in schizophrenia

Resting-state fMRI is associated with trauma experiences, mood and psychosis in Afro-descendants with bipolar disorder and schizophrenia

BACKGROUND

Bipolar disorder (BD) and schizophrenia (SCZ) may exhibit functional abnormalities in several brain areas, including the medial temporal and prefrontal cortex and hippocampus; however, a less explored topic is how brain connectivity is linked to premorbid trauma experiences and clinical features in non-Caucasian samples of SCZ and BD.

METHODS

Sixty-two individuals with SCZ (n = 20), BD (n = 21), and healthy controls (HC, n = 21) from indigenous and African ethnicity were submitted to clinical screening (Di-PAD), traumata experiences (ETISR-SF), cognitive and functional MRI assessment. The item psychosis/hallucinations in SCZ patients showed a negative correlation with the global efficiency (GE) in the right dorsal attention network. The items mania, irritable mood, and racing thoughts in the Di-PAD scale had a significant negative correlation with the GE in the parietal right default mode network.

CONCLUSIONS

Differences in the activation of specific networks were associated with earlier disease onset, history of physical abuse, and more severe psychotic and mood symptoms in SCZ and BD subjects of indigenous and black ethnicity. Findings provide further evidence on SZ and BD's brain connectivity disturbances, and their clinical significance, in non-Caucasian samples.

Improving Romantic Relationship Functioning Among Young Men With First-Episode Psychosis: Impact of a Novel Group Intervention

Previous research has highlighted many of the challenges faced by individuals with psychosis in romantic relationships. The present study aimed to evaluate the impact of a novel group intervention for men with first-episode psychosis (FEP) on dating success, romantic and sexual functioning, self-esteem, self-stigma, mentalizing skills, and symptomatology, while using a repeated single-case experimental design and comparing results across two treatment modalities (i.e., in-person or online). Twenty-seven participants from five treatment sites completed a 12-week group intervention. Qualitative data was also collected to assess participants' subjective experiences with the program. In both modalities, significant improvements were observed for romantic functioning, mentalizing skills, and symptomatology, with effect sizes ranging from small to large. Several participants also attended more dates and entered committed relationships after the intervention. Most participants were satisfied with the program and many felt that they had learned new skills and gained confidence in dating. Future research should replicate these findings in larger and more inclusive samples.

Dr. Smartphone, can you support my trauma? An informatics analysis study of App Store apps for trauma- and stressor-related disorders

Background

Psychological trauma is prevalent in developed countries, with prevalence rates and treatment needs exceeding health system capacity. As telemedicine and out-of-patient care are promoted, there has been an expansion of digital apps to compliment therapeutic stages in psychological trauma. To date there are no reviews that have compared these apps and their clinical utility. This study aims to identify the availability of trauma- and stressor-related mhealth apps, assess their functionality, and review their therapeutic abilities.

Methodology

The authors conducted a systematic search using an iPhone 13 Pro in the Australian IOS App Store to extract trauma- and stressor-related apps that resulted from the search criteria. A cross-adaptation of the Mobile App Rating Scale (MARS) and the Comprehensive App Evaluation Model (CAEM) were used as a framework to produce the mTrauma App Evaluation Conceptual Model and Informatics Framework. App content descriptors were analysed based on their general characteristics, usability, therapeutic focus, clinical utility, data integration. Following an applicability in concordance with psychological trauma-informed delivery.

Results

A total of 234 apps resulting from the search strategy were screened, with 81 apps that met the inclusion criteria. The majority of apps were marketed to 4+ to 17+ years of age, categorised as 'health and fitness', with the highest target markets observed for adolescents, children, parents, clinicians, and clients. A total of 43 apps (53.1%) contained a trauma-informed specified section, and 37 (45.7%) incorporated a section useful to support trauma-related symptoms. A significant number of apps there was an absence of therapeutic utility (in 32 apps (39.5%)). Most apps were supporting post-traumatic stress disorder-informed, cognitive behavioural therapy and eye movement desensitisation and reprocessing. Provision of psychoeducation, courses, guided sessions, trainings, self-reflection/journaling, symptom management and progress tracking were highly present.

Conclusions

Trauma-informed mobile apps are available in the App Store, expanding in its target market reach and usability, with an increase of creative psychotherapies being introduced alongside conventional modalities. However, based on the app descriptors, the scarcity of evidenced-based testimonials and therapeutic applicability remains questionable for clinical validity. Although mhealth tools are marketed as trauma-related, current available apps employ a multifunctional approach to general psychological symptomatology, through to associated comorbid conditions and emphasizes on passive activity. For higher uptake on user engagement, clinical application and validity, trauma-apps require curated specification to fulfil its role as complimentary psychological treatment.

Impact of Childhood Trauma and Adult Separation Anxiety Disorder on Quality of Life in Individuals with Schizophrenia

Background

Childhood trauma and anxiety disorders are common in individuals with schizophrenia. This study aimed to investigate the effects of childhood trauma and adult separation anxiety disorder on the quality of life of individuals with schizophrenia.

Methods

This cross-sectional study included 111 individuals with schizophrenia and 85 control subjects. The separation anxiety symptom inventory (SASI), adult separation anxiety questionnaire (ASAQ), Positive and Negative Syndrome Scale (PANSS), childhood trauma questionnaire (CTQ), and World Health Organization quality of life questionnaire (WHOQoL-BREF) were administered to the participants.

Results

More individuals with schizophrenia than control subjects were unemployed and single (p<0.05). Individuals with schizophrenia scored significantly higher on the SASI, ASAQ, and CTQ (p<0.05), whereas the control subjects scored significantly higher on the WHOQoL-BREF (p<0.05). ASAQ scores had mild positive correlations with total PANSS and PANSS subscale scores, and moderate positive correlations with total CTQ, CTQ emotional subscale scores, and CTQ physical abuse subscale scores. A negative moderate correlation was found between ASAQ and total WHOQoL-BREF scores. Mediation analysis revealed that CTQ scores significantly affected total WHOQoL-BREF and ASAQ scores. The model pathway for ASAQ scores showed a significant direct and indirect effect of CTQ on the total WHOQoL-BREF scores.

Conclusion

Childhood trauma predicts adult separation anxiety disorder, which partially mediates the impact of childhood trauma on quality of life in individuals with schizophrenia. Therapeutic interventions for adult separation anxiety disorder in individuals with schizophrenia and a history of childhood trauma may help increase their quality of life.

The Role of Childhood Trauma in Psychosis and Schizophrenia: A Systematic Review

Schizophrenia (SCZ) is a prevalent cause of disability worldwide. Distinguished mainly by psychosis, behavioral alterations could range from hallucinations to delusions. This systematic review examines evidence of a relationship between childhood trauma/adverse life events and psychosis, especially in SCZ. A methodical search provided reproducible results using these five databases: PubMed, ScienceDirect, Semantic Scholar, JSTOR, and Cochrane Library. The systematic search focused on articles published between July 2016 and July 2021. The search strategy utilized specific keywords relevant to SCZ, psychosis, and childhood trauma. The formulation of specified inclusion and exclusion criteria was necessary to ensure a comprehensive narrowed-down search, such as the inclusion of free full-text articles published or translated in English and exclusion of irrelevant subject areas. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a strategic search initially identified 741 articles; three additional articles were identified from citation searching. After relevance screening, duplicate removal, and quality appraisal, 12 studies from databases/registers and three from citation searching met the criteria proving relevance to our review with minimal evidence of bias. The final selected 15 studies included observational studies and reviews. A review of relevant data unveiled findings on childhood adversity, individual lived experiences, and their involvement in SCZ. Evidence suggests that certain neurobiological processes occur in brain after trauma. The inflammation and dysregulation from oxidative stress predispose patients to an at-risk-mental state, facilitating the progression to SCZ. This review encourages further evaluation of early trauma detection and the potential benefits of early intervention.

'I do not know where it comes from, I am suspicious of some childhood trauma' association of trauma with psychosis according to the experience of those affected

BACKGROUND

Trauma-related symptoms are often experienced after a first psychotic episode.

OBJECTIVE

In this study, we conduct a qualitative analysis of referred traumatic experiences of outpatients diagnosed with psychotic disorders.

METHOD

Focus groups were formed and in-depth interviews conducted with 30 participants, focusing on their experience with the disorder and the health care received. Given the frequency with which trauma and psychosis have been associated in the scientific literature, the nature of this relation is addressed as a secondary objective, via a qualitative analysis.

RESULTS

Analysis revealed two main themes in the patients' discourse. On many occasions, traumatic experiences were related to the development of the disorder. Although most participants referred to traumatic experiences during childhood, episodes during adult life were also reported, which may have triggered the disorder. The second theme was that of the interlocking relationship between the psychotic experience and certain coercive practices undergone during the provision of health care for psychosis, and the traumatic effects thus generated.

CONCLUSIONS

The participants considered both themes to be highly important. Accordingly, these issues should be carefully assessed and managed in order to provide appropriate person-centred care.

Attachment Style and Insight in Schizophrenia: a Cross-Sectional Study

Attachment theory provides a model for understanding impairments in social and interpersonal functioning. Schizophrenia is a neuropsychiatry disorder frequently associated with compromised social functioning and limited social support networks. However, the relationship between attachment style and psychopathology dimensions, including insight, isn't fully understood To determine whether there is a relationship between the attachment style and markers for severity of schizophrenia and insight. We conducted a cross-sectional study of 41 patients with schizophrenia and 34 patients with non-psychotic disorders used as a control group. Patients were assessed using semi-structured diagnostic interviews and self-reporting questionnaires, including Adult Attachment Scale-Revised. The schizophrenia group was also given the Positive and Negative Syndrome Scale and the Markova and Berrios Insight Scale. Insecure attachment was overrepresented in the schizophrenic group, and this difference was mainly accounted for lower levels of dependence, representing a moderate effect size (Cohen's d = 0.32). In the schizophrenia group, the closeness and the dependence subscale were negatively correlated with psychopathology severity. Using a multiple regression analysis, the insight was predicted by attachment anxiety, accounting for 20% of the total variance (R² = 0.199, p <0.05). Our data confirm previous evidence that insecure attachment is associated with schizophrenia and suggest that the less comfortable the patient is with closeness and intimacy the greater the severity of symptoms. Furthermore, our findings indicate that higher separation anxiety might predict a better insight.

A History of Trauma is Associated with Aggression, Depression, Non-Suicidal Self-Injury Behavior, and Suicide Ideation in First-Episode Psychosis

The association between trauma and psychosis outcomes is well-established, and yet the impact of trauma on comorbid clinical symptoms-such as aggression, non-suicidal self-injury behavior (NSSIB), suicide ideation, and suicide behavior-for those with psychosis is unclear. To effectively treat those with first-episode psychosis (FEP) and a history of trauma, we need to understand the impact of trauma on their whole presentation. FEP participants were recruited from an Early Psychosis Program (N = 187, ages 12-35, 72.2% male). Clinicians gathered history of trauma, aggression, and suicide data, and rated current symptom severity and functioning. Data was coded using clinician rated measures, self-report measures, and retrospective clinical chart review. Regression analyses examined whether trauma was associated with a history of aggression, suicidal ideation, suicide behavior, NSSIB, symptoms, and functioning. Trauma was associated with aggression, aggression severity and type of aggression (aggression towards others). Trauma was also associated with depression severity, suicide ideation, most severe suicide ideation, and NSSIB. Trauma was not associated with suicide behavior, severity of suicide behavior or psychosocial functioning. Integrating trauma treatment into FEP care could reduce rates of depression, aggression, suicide ideation, and NSSIB for those with a history of trauma. To reduce suicide attempt occurrence and improve functioning, more research is needed.

Severe childhood trauma and clinical and neurocognitive features in schizotypal personality disorder

OBJECTIVE

Literature suggests that childhood trauma increases vulnerability for schizophrenia-spectrum disorders, including schizotypal personality disorder (SPD). Yet, it remains unexplored whether childhood trauma predicts symptom load and the level of neurocognitive functioning in SPD.

METHOD

We included 225 individuals with SPD and 127 healthy controls. Childhood trauma was evaluated using the Childhood Trauma Questionnaire, and schizotypal traits were assessed using the Schizotypal Personality Questionnaire. Standard neurocognitive assessments covered six cognitive domains.

RESULTS

All types of reported childhood trauma were significantly associated with SPD, in a linear fashion. Severe sexual abuse showed the greatest magnitude of association with higher cognitive-perceptual load (e.g., ideas of reference, odd belief or magical thinking); severe emotional neglect was associated with interpersonal scores (e.g., excessive social anxiety, constricted affect) within the SPD group. SPD individuals who reported severe trauma showed worse cognitive functioning (i.e., working memory, verbal/visual learning and memory, as well as verbal fluency).

CONCLUSIONS

Particular severe childhood trauma types were associated with higher cognitive-perceptual and interpersonal symptoms in SPD, along with worse cognitive functioning. These findings highlight the need for clinicians to enquire about childhood trauma in SPD patients, since unaddressed early adverse experiences may carry long-term negative consequences.

Neurobiology and treatment of social cognition in schizophrenia: Bridging the bed-bench gap

Social cognition refers to the psychological processes involved in the perception, encoding, storage, retrieval, and regulation of information about others and ourselves. This process is essential for survival and reproduction in complex social environments. Recent evidence suggests that impairments in social cognition frequently occur in schizophrenia, mainly contributing to poor functional outcomes, including the inability to engage in meaningful work and maintain satisfying interpersonal relationships. With the ambiguous definition of social cognition, the neurobiology underlying impaired social cognition remains unknown, and the effectiveness of currently available intervention strategies in schizophrenia remain limited. Considering the advances and challenges of translational research for schizophrenia, social cognition has been considered a high-priority domain for treatment development. Here, we describe the current state of the framework, clinical concerns, and intervention approaches for social cognition in schizophrenia. Next, we introduce translatable rodent models associated with schizophrenia that allow the evaluation of different components of social behaviors, providing deeper insights into the neural substrates of social cognition in schizophrenia. Our review presents a valuable perspective that indicates the necessity of building bridges between basic and clinical science researchers for the development of novel therapeutic approaches in impaired social cognition in schizophrenia.
