Psychological interventions for acute psychiatric inpatients with schizophrenia-spectrum disorders: A systematic review and meta-analysis

Targeted psychological and psychosocial interventions for auditory hallucinations in persons with psychotic disorders: Protocol for a systematic review and meta-analysis

BACKGROUND

In recent years, a growing body of evidence has demonstrated the efficacy of non-pharmacological interventions for schizophrenia spectrum disorders (SSD) including positive symptoms such as auditory hallucinations (AH). However, clinical trials predominantly examine general treatment effects for positive symptoms. Therefore, previous research is lacking in comprehensive and clear evidence about psychological and psychosocial approaches that are primarily tailored to treat AH. To overcome this knowledge gap in the current literature, we will conduct a systematic review and meta-analysis to assess the efficacy of clearly targeted psychological and psychosocial interventions for AH in persons with SSD.

METHODS AND ANALYSIS

This study protocol has been developed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. We will include all randomized controlled trials analyzing the efficacy of targeted psychological and psychosocial interventions especially aimed at treating AH in SSD. We will include studies on adult patients with SSD experiencing AH. The primary outcome will be the change on a published rating scale measuring AH. Secondary outcomes will be delusions, overall symptoms, negative symptoms, depression, social functioning, quality of life, and acceptability (drop-out). We will search relevant databases and the reference lists of included literature. The study selection process will be conducted by two independent reviewers. We will conduct a random-effect meta-analysis to consider heterogeneity across studies. Analyses will be carried out by software packages in R. The risk of bias in each study will be evaluated using the Cochrane Risk of Bias tool. Assessment of heterogeneity and sensitivity analysis will be conducted.

DISCUSSION

The proposed study will augment the existing evidence by providing an overview of effective treatment approaches and their overall efficacy at treating AH in SSD. These findings will complement existing evidence that may impact future treatment implementations in clinical practice by addressing effective strategies to treat AH and therefore improve outcomes for the addressed population.

ETHICS AND DISSEMINATION

No ethical issues are foreseen. We will publish the results from this study in peer-reviewed journals and at relevant scientific conferences.

Targeting metacognitive change mechanisms in acute inpatients with psychotic symptoms: feasibility and acceptability of a modularized group intervention

Emerging evidence suggests the usefulness of psychological interventions targeting metacognitive change mechanisms in patients experiencing psychosis. Although many of these patients are treated in acute psychiatric contexts, only few studies have adapted such interventions for acute inpatient settings. The present study aimed to assess the feasibility, acceptability, and preliminary clinical outcomes of a novel modularized group intervention focusing on different aspects of metacognitive change mechanisms. In particular, the intervention aims to reduce patients' acute symptoms by enhancing cognitive insight and to relieve distress via cognitive defusion (i.e. coping). A sample of 37 participants with acute psychosis received up to nine sessions of the intervention. Baseline and post-intervention assessments were conducted for general psychopathology, psychotic symptoms, global functioning, and symptom distress. Measures of change mechanisms were assessed before and after the respective treatment module. Participants' experiences were explored in feedback questionnaires and interviews. Recruitment, retention, and attendance rate met the pre-set feasibility benchmark of 80%. The intervention was well received by participants, who emphasised the group's clear structure, positive atmosphere, and helpful contents. Response rates were high and linear mixed models revealed significant medium-to-large time effects on all clinical outcomes. As expected, increase in hypothesised change mechanisms cognitive insight and decrease in cognitive fusion was found. However, the uncontrolled design limits interpreting clinical effects. The study provides evidence that an intervention based on a metacognitive model is feasible and acceptable for acute inpatients with psychosis. Positive results on clinical outcomes and change mechanisms warrant further exploration in a randomized controlled trial.

Factors associated with recovery during schizophrenia and related disorders: A review of meta-analysis

BACKGROUND

The spectrum of schizophrenia disorders (SSD) is a severe mental disorder. It is one of the main medical causes of disability that generates high health and social costs.

OBJECTIVE

To analyze the factors associated with clinical recovery (CR) (symptomatic remission-SR and functional recovery-FR) and personal recovery (PR) in people diagnosed with SSD.

METHODS

14 meta-analyses focused on recovery were reviewed following the PRISMA model statements. 95 % of CI was established.

RESULTS

Shorter Duration of Untreated Psychosis (Zr = 0.24, [0.17, 0.30]) and total Duration of Untreated Illness (Zr = 0.34, [0.20, 0.48]) were related to greater SR and general functioning, respectively. Resilience was the variable with the greatest effect on FR (Zr = 0.67, [0.63, 0.71]). Premorbid adjustment (Zr = 0.34, [0.18, 0.49]) and physical intervention (Zr = 0.71, [0.55, 0.86]) had the greatest effect on occupational and social functioning, respectively. Less severe affective symptoms were related to greater PR (Zr = 0.46, [0.42, 0.50]). There are differences between affective SR and the other types of SR (Zr(SR-A - SR-) = 0.13, Qb = 6.51, p = 0.011), (Zr(SR-A - SR+) = 0.20, Qb = 8.52, p = 0.004), (Zr(SR-A - SR) = 0.18, Qb = 19.29, p = 0.0001). In all, resilience was associated with greater recovery (Zr = 0.67, [0.53, 0.80]), with the global effect being greater on PR than on CR (Zr(PR-CR) = 0.07, Qb = 3.45, p = 0.05).

CONCLUSIONS

Resilience was the variable most strongly associated with recovery. Symptomatic or functional improvement obtained less statistical weight.

Cognitive behavioural therapy for psychosis: The end of the line or time for a new approach?

PURPOSE

Following its introduction in the early 1990s, cognitive behavioural therapy for psychosis (CBTp) has been evaluated in a large number of clinical trials and is now established as a recommended treatment in the UK National Health Service and elsewhere in the world. Meta-analyses, however, indicate modest effects compared to treatment as usual or comparison therapies such as supportive counselling. Here, we seek to identify factors impacting the effectiveness of CBTp, and avenues for future psychotherapy research that may improve outcomes.

METHOD

We outline two recent umbrella reviews and discuss factors likely to impact the effectiveness of CBTp.

RESULTS

Modest effect sizes from meta-analyses mask heterogeneous outcomes, with some people benefiting and others possibly being harmed by therapy. Common factors such as the therapeutic alliance play an important role in determining outcomes but have been largely neglected by CBTp researchers. There is also the promise of improving outcomes by identifying and targeting the psychological mechanisms that either maintain psychotic symptoms (e.g. worry) or are causally implicated (e.g. trauma).

CONCLUSIONS

It is unlikely that everyone with psychosis will be equally responsive to the same therapeutic protocols. We need a new, personalised psychotherapy approach to CBTp research and practice, and can learn from research for anxiety and depression examining predictors of therapeutic response to inform treatment decisions. Precision psychological therapies informed by a combination of individual characteristics, common factors and a focus on specific mechanisms will require new research strategies and are likely to lead to improved outcomes for people with psychosis.

The schizophrenia syndrome, circa 2024: What we know and how that informs its nature

With new data about different aspects of schizophrenia being continually generated, it becomes necessary to periodically revisit exactly what we know. Along with a need to review what we currently know about schizophrenia, there is an equal imperative to evaluate the construct itself. With these objectives, we undertook an iterative, multi-phase process involving fifty international experts in the field, with each step building on learnings from the prior one. This review assembles currently established findings about schizophrenia (construct, etiology, pathophysiology, clinical expression, treatment) and posits what they reveal about its nature. Schizophrenia is a heritable, complex, multi-dimensional syndrome with varying degrees of psychotic, negative, cognitive, mood, and motor manifestations. The illness exhibits a remitting and relapsing course, with varying degrees of recovery among affected individuals with most experiencing significant social and functional impairment. Genetic risk factors likely include thousands of common genetic variants that each have a small impact on an individual's risk and a plethora of rare gene variants that have a larger individual impact on risk. Their biological effects are concentrated in the brain and many of the same variants also increase the risk of other psychiatric disorders such as bipolar disorder, autism, and other neurodevelopmental conditions. Environmental risk factors include but are not limited to urban residence in childhood, migration, older paternal age at birth, cannabis use, childhood trauma, antenatal maternal infection, and perinatal hypoxia. Structural, functional, and neurochemical brain alterations implicate multiple regions and functional circuits. Dopamine D-2 receptor antagonists and partial agonists improve psychotic symptoms and reduce risk of relapse. Certain psychological and psychosocial interventions are beneficial. Early intervention can reduce treatment delay and improve outcomes. Schizophrenia is increasingly considered to be a heterogeneous syndrome and not a singular disease entity. There is no necessary or sufficient etiology, pathology, set of clinical features, or treatment that fully circumscribes this syndrome. A single, common pathophysiological pathway appears unlikely. The boundaries of schizophrenia remain fuzzy, suggesting the absence of a categorical fit and need to reconceptualize it as a broader, multi-dimensional and/or spectrum construct.

A Call for Integrated Psychiatry-Psychology Collaboration on Consult-Liaison Services: Experiences of a Psychology Extern and Recommendations for Collaborative Care

Few institutions have integrated psychologists into consult-liaison (CL) psychiatry services caring for patients with medical conditions and comorbid serious mental illnesses (SMI). To our knowledge, no studies have explored the experiences of an integrated pre-doctoral psychologist on a CL psychiatry service and applications of collaborative care. The present study aims to 1) highlight the experiences of a psychology extern on an adult CL psychiatry service in a public academic hospital, and 2) apply a collaborative care framework to provide recommendations for implementing integrated psychiatry-psychology collaboration. A semi-structured qualitative interview was performed with the team's psychology extern to elicit practice goals and setting. As of June 2022, the psychology extern saw 76 inpatient adults over the year-long externship period. Through diverse case vignettes, we illustrate the extern's unique roles in providing psychotherapeutic interventions to enhance patients' coping skills. We further found that embedding a psychology extern within the CL psychiatry service follows the integrated model of collaborative care. We thus apply a collaborative care framework to guide CL services in using multidisciplinary teams to improve care quality for inpatient adults. Leveraging the expertise of a psychology extern in real-time collaboration with CL psychiatry teams can enhance patient-centered care and warrants broader institutional implementation. Future studies are needed to explore the efficacy of integrated psychiatry-psychology collaboration on provider perspectives and clinical outcomes.

An international research agenda for clozapine-resistant schizophrenia

Treatment-resistant symptoms occur in about a third of patients with schizophrenia and are associated with a substantial reduction in their quality of life. The development of new treatment options for clozapine-resistant schizophrenia constitutes a crucial, unmet need in psychiatry. Additionally, an overview of past and possible future research avenues to optimise the early detection, diagnosis, and management of clozapine-resistant schizophrenia is unavailable. In this Health Policy, we discuss the ongoing challenges associated with clozapine-resistant schizophrenia faced by patients and health-care providers worldwide to improve the understanding of this condition. We then revisit several clozapine guidelines, the diagnostic tests and treatment options for clozapine-resistant schizophrenia, and currently applied research approaches in clozapine-resistant schizophrenia. We also suggest methodologies and targets for future research, divided into innovative nosology-oriented field trials (eg, examining dimensional symptom staging), translational approaches (eg, genetics), epidemiological research (eg, real-world studies), and interventional studies (eg, non-traditional trial designs incorporating lived experiences and caregivers' perspectives). Finally, we note that low-income and middle-income countries are under-represented in studies on clozapine-resistant schizophrenia and propose an agenda to guide multinational research on the cause and treatment of clozapine-resistant schizophrenia. We hope that this research agenda will empower better global representation of patients living with clozapine-resistant schizophrenia and ultimately improve their functional outcomes and quality of life.

Developing a mechanism-based therapy for acute psychiatric inpatients with psychotic symptoms: an Intervention Mapping approach

Background

Treatment guidelines for psychosis recommend offering psychotherapy already in the acute illness phase. However, there is a lack of available interventions adapted to the specific needs and key change mechanisms of inpatients experiencing severe symptoms and crisis. In this article we outline the scientific development process of a needs-oriented and mechanism-based group intervention for acute psychiatric inpatients with psychosis (MEBASp).

Methods

To guide our intervention design, we used Intervention Mapping (IM), a six-step framework for developing evidence-based health interventions that consisted of an extensive literature review, an in-depth problem definition and needs analysis, the modeling of change mechanisms and outcomes and the production of an intervention prototype.

Results

Our low-threshold modularized group intervention consists of nine stand-alone sessions (two per week) within three modules and targets different aspects of metacognitive and social change mechanisms. Module I and II aim to reduce acute symptoms by fostering cognitive insight, Module III focuses on reducing distress via cognitive defusion. Therapy contents are adapted from existing metacognitive treatments such as the Metacognitive Training and presented in a destigmatizing, simply understandable and experience-oriented way.

Conclusion

MEBASp is currently evaluated in a single-arm feasibility trial. Using a systematic and rigorous development methodology and providing a detailed description of the development steps demonstrated to be invaluable in improving the intervention's scientific foundation, validity, and replicability for similar research.

[Current evidence for various inpatient psychotherapy programs in the treatment of psychoses-A narrative review article]

BACKGROUND

The analysis of the efficacy of evidence-based psychotherapy for patients with psychotic disorders has mostly been carried out in the outpatient field. In the inpatient field the efficacy is sometimes difficult to assess due to different healthcare systems.

OBJECTIVE

The aim of this narrative review is to summarize international guidelines and meta-analyses on the efficacy of inpatient psychotherapeutic treatment strategies for patients with psychotic disorders. Based on this, recommendations for disorder-specific ward concepts for acute and postacute fields are formulated.

METHODS

The German S3 guidelines, international guidelines, current meta-analyses and primary studies on psychological interventions in the treatment of psychotic disorders were included. Based on the results, recommendations for the inpatient psychotherapeutic treatment in various phases of treatment were formulated (acute phase and postacute phase).

RESULTS

In the acute phase a combination of cognitive behavioral therapy (CBTp) in the individual setting and family interventions in the group setting as well as metacognitive training (MCT acute) is effective and recommended. In the postacute phase, in addition to individual and group CBTp and family interventions, psychoeducation, social skills training and cognitive remediation have been shown to be effective and are recommended.

DISCUSSION

The suggested recommendations for concrete interventions in various treatment phases and the evidence base are critically discussed and recommendations for the structure of wards are presented.

Efficacy and acceptability of psychosocial interventions in schizophrenia: systematic overview and quality appraisal of the meta-analytic evidence

Psychosocial interventions are recommended in schizophrenia and first-episode psychosis/early psychosis (EP). Nevertheless, literature is heterogeneous and often contradictory. We conducted an umbrella review of (network) meta-analyses of randomized controlled trials (RCTs) comparing psychosocial interventions vs treatment as usual (TAU)/active interventions(ACTIVE)/MIXED controls. Primary outcome was total symptoms (TS); secondary outcomes were positive/negative/depressive symptoms (PS/NS/DS), cognition, functioning, relapse, hospitalization, quality of life (QoL), treatment discontinuation. Standardized mean difference (SMD)/odds ratio (OR)/risk ratio (RR) vs TAU/ACTIVE/MIXED were summarized at end-of-treatment (EoT)/follow-up (FU). Quality was rated as high/medium/low (AMSTAR-PLUS). Eighty-three meta-analyses were included (RCTs = 1246; n = 84,925). Against TAU, regarding TS, Early Intervention Services (EIS) were superior EoT/FU in EP (SMD = -0.32/-0.21), cognitive behavioral therapy (CBT) in schizophrenia EoT/FU (SMD = -0.38/-0.19). Regarding secondary outcomes, in EP, EIS were superior for all outcomes EoT except cognition, and at FU for PS/NS/QoL, specific family interventions (FI-s) prevented relapse EoT; in schizophrenia, superiority emerged EoT for CBT for PS/NS/relapse/functioning/QoL; psychoeducation (EDU)/any FI for relapse; cognitive remediation therapy (CRT) for cognition/functioning; and hallucination-focused integrative treatment for PS. Against ACTIVE, in EP, mixed family interventions (FI-m) were superior at FU regarding TS (SMD = -0.61) and for functioning/relapse among secondary outcomes. In schizophrenia, regarding TS, mindfulness and social skills training (SST) were superior EoT, CBT at FU; regarding secondary outcomes superiority emerged at EoT for computerized cognitive drill-and-practice training for PS/DS, CRT for cognition/functioning, EDU for relapse, individual placement and support (IPS) for employment; and at FU CBT for PS/NS. Against MIXED, in schizophrenia, CRT/EDU were superior for TS EoT (d = -0.14/SMD = -0.33), CRT regarding secondary outcomes EoT for DS/social functioning, both EoT/FU for NS/cognition/global functioning; compensatory cognitive interventions for PS/functioning EoT/FU and NS EoT; CBT for PS at FU, and EDU/SST for relapse EoT. In conclusion, mental health services should consider prioritizing EIS/any FI in EP and CBT/CRT/any FI/IPS for schizophrenia, but other interventions may be helpful for specific outcomes.

Schizophrenia: A Narrative Review of Etiopathogenetic, Diagnostic and Treatment Aspects

Although schizophrenia is currently conceptualized as being characterized as a syndrome that includes a collection of signs and symptoms, there is strong evidence of heterogeneous and complex underpinned etiological, etiopathogenetic, and psychopathological mechanisms, which are still under investigation. Therefore, the present viewpoint review is aimed at providing some insights into the recently investigated schizophrenia research fields in order to discuss the potential future research directions in schizophrenia research. The traditional schizophrenia construct and diagnosis were progressively revised and revisited, based on the recently emerging neurobiological, genetic, and epidemiological research. Moreover, innovative diagnostic and therapeutic approaches are pointed to build a new construct, allowing the development of better clinical and treatment outcomes and characterization for schizophrenic individuals, considering a more patient-centered, personalized, and tailored-based dimensional approach. Further translational studies are needed in order to integrate neurobiological, genetic, and environmental studies into clinical practice and to help clinicians and researchers to understand how to redesign a new schizophrenia construct.

Description of a culture-sensitive, low-threshold psychoeducation intervention for asylum seekers (Tea Garden)

Background

Asylum seekers often suffer from high levels of mental distress. However, as a result of a lack of knowledge about mental health and health care, as well as cultural and language barriers, the utilization of mental health care in Western host countries is often difficult for these individuals. Reducing these barriers may thus be a crucial first step towards appropriate mental health care. Previous research showed that psychoeducation may be helpful in this regard.

Method

The current manuscript describes a short, low-threshold and transdiagnostic intervention named ‘Tea Garden (TG)’. The TG aims to increase specific knowledge about mental health problems and available treatments, and may improve psychological resilience and self-care. In this manuscript, we specifically focus on culturally sensitive facets, following the framework proposed by Heim and colleagues (2021, https://doi.org/10.32872/cpe.6351), and lessons learned from three independent pilot evaluations (Ns = 31; 61; 20).

Results

The TG was found to be feasible and quantitative results showed that it was helpful for male and female asylum seekers from different countries of origin (e.g., Afghanistan, Syria, Pakistan, Iraq) and with different educational levels. Interestingly, even asylum seekers who had already been in Germany or Austria for three or more years benefited from the TG.

Conclusion

The TG specifically aims to be culture-sensitive rather than culture-specific, to be transdiagnostic rather than focused on specific mental disorders, and to be suitable for asylum seekers who are still in the insecure process of applying for asylum. It may also be helpful for distressed asylum seekers who do not fulfill the criteria for a mental disorder, and for healthy asylum seekers who could use the knowledge gained in the TG to help others.

There is a lack of short, low-threshold, and culture-sensitive interventions for asylum seekers.

A transdiagnostic intervention, named ‘Tea Garden’ (TG), is described and findings of pilot evaluations are reported.

The TG aims to increase knowledge about mental health (care), and improve resilience and self-care.

The TG was found to be helpful for refugees from different origins and with different educational levels.
