Childhood interpersonal trauma and premorbid social adjustment as predictors of symptom remission in first episode psychosis

Childhood trauma types in relation to antipsychotic effectiveness in schizophrenia spectrum disorders: A prospective, pragmatic, randomized controlled study

Treatment with antipsychotics (APs) for schizophrenia spectrum disorders (SSDs) is generally effective, however, a significant proportion does not respond favorably. Childhood trauma (CT) subtypes (physical, sexual, and emotional abuse, physical and emotional neglect) could influence treatment effectiveness; however, research is scarce. Heterogeneity in AP response could be explained by differentiating by CT subtype. The present study was based on the Bergen-Stavanger-Trondheim-Innsbruck (BeSt InTro) study. CTQ-SF assessed CT subtypes in SSDs (n = 98). CT subtypes were examined in relation to psychosis symptoms measured by PANSS during one year of treatment with APs, by means of linear mixed effects (LME) models. Results were significant for CT subtypes, where increased levels of sexual abuse and physical neglect were associated with increased mean levels of psychosis symptoms throughout the course of treatment from baseline to 52 weeks. AP effectiveness may thus be influenced by CT subtype in SSDs. The results support clinical guidelines recommending a focus on assessment and treatment of trauma in SSDs.

Childhood trauma and treatment resistance in first-episode psychosis: Investigating the role of premorbid adjustment and duration of untreated psychosis

BACKGROUND

Early identification of treatment non-response in first-episode psychosis (FEP) is essential to outcome. Despite indications that exposure to childhood trauma (CT) can have adverse effects on illness severity, its impact on treatment non-response and the interplay with other pre-treatment characteristics is sparsely investigated. We use a lack of clinical recovery as an early indicator of treatment resistance to investigate the relationship between CT and treatment resistance status at one-year follow-up and the potential mediation of this effect by other pre-treatment characteristics.

METHODS

This prospective one-year follow-up study involved 141 participants recruited in their first year of treatment for a schizophrenia-spectrum disorder. We investigated clinical status, childhood trauma (CT), premorbid adjustment (PA), and duration of untreated psychosis (DUP) at baseline and clinical status at one-year follow-up. Ordinal regression analyses were conducted to investigate how PA and DUP affected the relationship between CT and one-year outcome in FEP.

RESULTS

45 % of the FEP sample reported moderate to severe CT, with significantly higher levels of CT in the early treatment resistant group compared to participants with full or partial early recovery. Ordinal regression analysis showed that CT was a significant predictor of being in a more severe outcome group (OR = 4.59). There was a partial mediation effect of PA and a full mediation effect of DUP on the effect of CT on outcome group membership.

DISCUSSION

Our findings indicate that reducing treatment delays may mitigate the adverse effects of CT on clinical outcomes and support the inclusion of broad trauma assessment in FEP services.

How first-episode psychosis patients' subjective beliefs about their childhood trauma's causal effect provide support for potential schizophrenia subtypes

BACKGROUND

Childhood and adolescent trauma is a risk factor for developing psychosis-spectrum disorders. The current study aimed to assess how childhood trauma might predict psychosis symptomatology, and how patients' beliefs of whether trauma is the cause of psychosis might affect this association.

METHODS

Ninety-six first-episode psychosis patients were assessed for childhood traumatic experiences with the Brief Betrayal Trauma Survey, and for psychosis symptoms with the Positive and Negative Syndrome Scale.

RESULTS

Non-interpersonal trauma predicted higher positive symptoms, whereas more trauma domains experienced predicted lower negative symptoms. Almost half of the participants believed trauma to be related to psychosis, were 12 times more likely to reexperience trauma through psychosis, and had higher excitative and emotional symptoms. Non-interpersonal trauma also predicted higher positive symptoms in this group. Those who did not believe trauma to be the cause of psychosis had higher negative symptoms, and a negative dose-response was found for negative and disorganised symptoms, in which more trauma domains experienced predicted lower scores.

CONCLUSIONS

Results imply two traumagenic pathways to psychosis, one characterised by positive, excitative, and emotional symptoms, and one negative subtype, characterised by negative and disorganised symptoms. Clinical implications for how findings might contribute to better treatments are discussed.

Trauma and psychosis: The mediating role of premorbid adjustment and recent stressful events in a 3-year longitudinal study

BACKGROUND

Some of the most-studied environmental factors that can contribute to the development of psychosis are the adversities experienced at an early age. Among these, childhood interpersonal trauma (CIT) has been considered especially influential in the onset of the disease. The aim of the study was to explore the relationship between CIT and the first episode of psychosis (FEP), as well as the relationship between CIT and clinical and functional outcomes 3 years after illness onset.

METHODS

A total of 278 patients with a FEP and 52 healthy controls were studied. Logistic regression analysis was carried out to examine the explained variation by CIT at the beginning of psychosis. Recent stressful events and premorbid adjustment related to CIT, were introduced in path analyses to determine their mediating effects between CIT and the disease and its clinical and functional results.

RESULTS

Mediation analyses showed that CIT was indirectly associated with belonging to the FEP group through recent stressful events (Effect = 0.981; SE = 0.323; CI = 0.485 to 1.761). Premorbid academic adjustment in late adolescence mediated the relationship between CIT and clinical and functional outcomes, specifically in the measurements of the Scales for Assessment of Positive and Negative Symptoms, in the Brief Psychiatric Rating Scale, and in the Disability Assessment Scale.

CONCLUSIONS

These findings suggest that early traumatic experiences play an important role in the FEP. Early intervention that promotes good academic adjustment during adolescence and/or avoids retraumatisation could positively impact both the onset and the course of psychotic illness.

Latent Profiles of Premorbid Adjustment in Schizophrenia and Their Correlation with Measures of Recovery

Premorbid adjustment (PA) has classically been defined as psychosocial functioning in the areas of education, occupation, social and interpersonal relationships prior to evidence of characteristic positive symptomatology. It is a concept which possesses ample evidence regarding its predictive nature for the course of Schizophrenia. The study aimed to analyze the latent profiles of premorbid adjustment and their relationship with symptomatology, functionality, subjective recovery, stigma resistance and years of untreated psychosis. Latent class analysis (LCA) was used to elaborate a solution of three premorbid adjustment profiles in a sample of 217 patients diagnosed with Schizophrenia from Public Mental Health Centers in the city of Arica, Chile. The results show that premorbid adjustment was significantly correlated with recovery indicators and that latent profiles of better premorbid adjustment predict better outcomes in subjective recovery and stigma resistance. The results show that premorbid adjustment not only has implications for the severity of the disorder, but that psychosocial functioning prior to psychosis affects the patient's subjectivity, the representation of the disorder and the recovery process.

Gender Differences in Clinical and Psychosocial Features Among Persons With Schizophrenia: A Mini Review

An extensive literature regarding gender differences relevant to several aspects of schizophrenia is nowadays available. It includes some robust findings as well as some inconsistencies. In the present review, we summarize the literature on gender differences in schizophrenia relevant to clinical and social outcome as well as their determinants, focusing on clinical variables, while gender differences on biological factors which may have an impact on the outcome of the disorder were not included herewith. Consistent findings include, in male with respect to female patients, an earlier age of illness onset limited to early- and middle-onset schizophrenia, a worse premorbid functioning, a greater severity of negative symptoms, a lower severity of affective symptoms and a higher rate of comorbid alcohol/substance abuse. Discrepant findings have been reported on gender differences in positive symptoms and in social and non-social cognition, as well as in functional outcome and rates of recovery. In fact, despite the overall finding of a more severe clinical picture in males, this does not seem to translate into a worse outcome. From the recent literature emerges that, although some findings on gender differences in schizophrenia are consistent, there are still aspects of clinical and functional outcome which need clarification by means of further studies taking into account several methodological issues.
