Metacognitive profiles in individuals with a first episode of psychosis and their relation to social functioning and perceived social support

Link between metacognition and social cognition in schizophrenia: a systematic review and meta-analysis

Introduction

Metacognition is the ability to reflect on one's own cognitive processes, monitor and regulate them to enhance mental performance. Social cognition involves the capacity to perceive and respond to social cues from others. The study of metacognition and social cognition is an expanding research field in psychiatry. Both domains are related to neurocognition, symptoms and psychosocial functioning in schizophrenia. Understanding the relationship between social cognition and metacognition may be pivotal for enhancing the treatment of cognitive symptoms in schizophrenia.

Methods

We conducted a PRISMA systematic review and meta-analysis on quantitative studies comparing metacognition to social cognitive outcomes in adult outpatients with a schizophrenia spectrum disorder. Reports were retrieved from the Medline, ScienceDirect and PsycINFO databases up to July 13th, 2023. Risk of bias was assessed with the Cochrane tool.

Results

Our review included 1,036 participants across 17 reports, with 12 reports included in the meta-analysis. We found a significant positive correlation (r = 0.28, 95% CI: [0.14, 0.41]) between social cognition and metacognition. Subgroup analyses indicated that metacognition was specifically associated with theory of mind, attribution, and emotion processing. Different patterns of correlations were observed according to the assessment of metacognition and its subdimensions.

Conclusion

Despite discrepancies among the included studies, no publication bias was detected. The results suggest that metacognition and social cognition are distinct but related constructs. Those processes should be assessed and treated together, along with neurocognition, in schizophrenia.

Metacognitive monitoring in schizotypy: Systematic literature review and new empirical data

BACKGROUND AND OBJECTIVES

Deficits in metacognition, the ability to monitor one's own mental states, are key elements of the functional pathology of schizophrenia spectrum disorders. Little is known, however, about the integrity of metacognitive processes in subclinical schizotypy. The purpose of the present investigation was two-fold: First, we conducted a preregistered, systematic literature review to synthesize previous research efforts on the role of metacognition in schizotypy. Second, we investigated the relationship between self-reported dimensions of schizotypy and psychometric as well as behavioral measures of metacognition in a preregistered online study.

METHODS

A large sample (N = 330) completed a questionnaire battery and an episodic memory experiment; task-based metacognition was tapped via trial-by-trial confidence ratings.

RESULTS

In keeping with findings from our literature review, higher schizotypy was associated with diminished introspective insight and an overly self-referential and maladaptive metacognitive style in metacognition questionnaires. Importantly, low task-based metacognitive efficiency was predictive of high levels of cognitive disorganization, whereas task-related overconfidence (i.e., increased metacognitive bias) was linked with positive schizotypy.

LIMITATIONS

Due to the comparatively small number of k = 20 studies meeting our inclusion criteria, the systematic literature review provides only preliminary indications for potential conclusions. Furthermore, control over potential disturbing influences in the experimental study was limited due to its online format.

CONCLUSIONS

Overall, we provide evidence for specific metacognitive deficits in schizotypy and discuss a potential continuity of preserved and impaired aspects of metacognitive monitoring along the psychosis continuum.

Investigating the relationship between specific negative symptoms and metacognitive functioning in psychosis: A systematic review

BACKGROUND

Disrupted metacognition is implicated in development and maintenance of negative symptoms, but more fine-grained analyses would inform precise treatment targeting for individual negative symptoms.

AIMS

This systematic review identifies and examines datasets that test whether specific metacognitive capacities distinctly influence negative symptoms.

MATERIALS & METHODS

PsycINFO, EMBASE, Medline and Cochrane Library databases plus hand searching of relevant articles, journals and grey literature identified quantitative research investigating negative symptoms and metacognition in adults aged 16+ with psychosis. Authors of included articles were contacted to identify unique datasets and missing information. Data were extracted for a risk of bias assessment using the Quality in Prognostic Studies tool.

RESULTS

85 published reports met criteria and are estimated to reflect 32 distinct datasets and 1623 unique participants. The data indicated uncertainty about the relationship between summed scores of negative symptoms and domains of metacognition, with significant findings indicating correlation coefficients from 0.88 to -0.23. Only eight studies investigated the relationship between metacognition and individual negative symptoms, with mixed findings. Studies were mostly moderate-to-low risk of bias.

DISCUSSION

The relationship between negative symptoms and metacognition is rarely the focus of studies reviewed here, and negative symptom scores are often summed. This approach may obscure relationships between metacognitive domains and individual negative symptoms which may be important for understanding how negative symptoms are developed and maintained.

CONLCLUSION

Methodological challenges around overlapping participants, variation in aggregation of negative symptom items and types of analyses used, make a strong case for use of Individual Participant Data Meta-Analysis to further elucidate these relationships.

Social Dysfunction in Psychosis Is More Than a Matter of Misperception: Advances From the Study of Metacognition

Many with psychosis experience substantial difficulties forming and maintaining social bonds leading to persistent social alienation and a lack of a sense of membership in a larger community. While it is clear that social impairments in psychosis cannot be fully explained by symptoms or other traditional features of psychosis, the antecedents of disturbances in social function remain poorly understood. One recent model has proposed that deficits in social cognition may be a root cause of social dysfunction. In this model social relationships become untenable among persons diagnosed with psychosis when deficits in social cognition result in inaccurate ideas of what others feel, think or desire. While there is evidence to support the influence of social cognition upon social function, there are substantial limitations to this point of view. Many with psychosis have social impairments but not significant deficits in social cognition. First person and clinical accounts of the phenomenology of psychosis also do not suggest that persons with psychosis commonly experience making mistakes when trying to understand others. They report instead that intersubjectivity, or the formation of an intimate shared understanding of thoughts and emotions with others, has become extraordinarily difficult. In this paper we explore how research in metacognition in psychosis can transcend these limitations and address some of the ways in which intersubjectivity and more broadly social function is compromised in psychosis. Specifically, research will be reviewed on the relationship between social cognitive abilities and social function in psychosis, including measurement strategies and limits to its explanatory power, in particular with regard to challenges to intersubjectivity. Next, we present research on the integrated model of metacognition in psychosis and its relation to social function. We then discuss how this model might go beyond social cognitive models of social dysfunction in psychosis by describing how compromises in intersubjectivity occur as metacognitive deficits leave persons without an integrated sense of others' purposes, relative positions in the world, possibilities and personal complexities. We suggest that while social cognitive deficits may leave persons with inaccurate ideas about others, metacognitive deficits leave persons ill equipped to make broader sense of the situations in which people interact and this is what leaves them without a holistic sense of the other and what makes it difficult to know others, share experiences, and sustain relationships. The potential of developing clinical interventions focused on metacognition for promoting social recovery will finally be explored.

[Metacognitive deficit in schizophrenia: Characteristics and links]

OBJECTIVES

Research indicates that many patients with schizophrenia experience deficits in metacognitive capacity defined as the ability to form complex representations of themselves and others. The aim of the current study was to assess metacognitive deficit in patients with schizophrenia. These variables were collected together with many other sociodemographic, clinical and therapeutic data.

METHODS

We conducted a descriptive and analytical cross-sectional study in the psychiatry department at the Hedi Chaker University Hospital in Sfax (Tunisia). Patients were in a non-acute phase, defined by the absence of any psychiatric symptoms during the last four weeks, also, no changes in medication during the previous month had been required. An informed written consent was obtained, following which patients completed questionnaires assessing sociodemographic and clinical data during structured interviews. Symptoms and severity of the illness were assessed using the Positive and Negative Symptoms Scale (PANSS). Insight was assessed using the Insight Scale (Q8). In addition, the Metacognition Assessment Scale-Abbreviated (MAS-A) was used to assess metacognitive capacities. The MAS-A contains four dimensions: self-reflectivity, awareness of the mind of others, decentration, and mastery. Higher scores reflect an ability to effectively respond to psychological challenges on the basis of psychological knowledge.

RESULTS

We recruited 74 adults with schizophrenia disorder. The diagnosis was with DSM5. Their average age was 45 years (SD=9.84 years) with a sex ratio (M/F) of 1.552. Nineteen patients (25.5%) were married, and low educational level was present in 43% of cases. Forty patients (54%) were unemployed. Metacognitive deficit was detected in all the patients. They had low levels in all four dimensions of metacognition. The most affected dimension in our series was "Mastery". All patients had an overall insight score less than six (the average score was 2.73) with poor awareness in 62% of patients. The main factors correlated with metacognitive deficit were: occupational inactivity (P-0.015), Primary education level (P=0.045), tobacco consumption (P=0.002), low insight (P-0.001), negative symptomatology (P<10-3) and the use of first generation of antipsychotics (P=0.003). The multivariate analysis showed that three factors (occupational inactivity, low insight and the presence of negative symptomatology) were predictors of metacognitive deficits.

CONCLUSION

Based on our results, occupational inactivity, negative symptomatology and low insight are predictors of metacognitive deficit in schizophrenia. Specific therapeutics should be proposed to act on these factors. A metacognitive training program, tailored to this vulnerable population, is a priority to improve their quality of life.

Increased regional homogeneity modulated by metacognitive training predicts therapeutic efficacy in patients with schizophrenia

Previous studies have demonstrated the efficacy of metacognitive training (MCT) in schizophrenia. However, the underlying mechanisms related to therapeutic effect of MCT remain unknown. The present study explored the treatment effects of MCT on brain regional neural activity using regional homogeneity (ReHo) and whether these regions' activities could predict individual treatment response in schizophrenia. Forty-one patients with schizophrenia and 20 healthy controls were scanned using resting-state functional magnetic resonance imaging. Patients were randomly divided into drug therapy (DT) and drug plus psychotherapy (DPP) groups. The DT group received only olanzapine treatment, whereas the DPP group received olanzapine and MCT for 8 weeks. The results revealed that ReHo in the right precuneus, left superior medial prefrontal cortex (MPFC), right parahippocampal gyrus and left rectus was significantly increased in the DPP group after 8 weeks of treatment. Patients in the DT group showed significantly increased ReHo in the left ventral MPFC/anterior cingulate cortex (ACC), left superior MPFC/middle frontal gyrus (MFG), left precuneus, right rectus and left MFG, and significantly decreased ReHo in the bilateral cerebellum VIII and left inferior occipital gyrus (IOG) after treatment. Support vector regression analyses showed that high ReHo levels at baseline in the right precuneus and left superior MPFC could predict symptomatic improvement of Positive and Negative Syndrome Scale (PANSS) after 8 weeks of DPP treatment. Moreover, high ReHo levels at baseline and alterations of ReHo in the left ventral MPFC/ACC could predict symptomatic improvement of PANSS after 8 weeks of DT treatment. This study suggests that MCT is associated with the modulation of ReHo in schizophrenia. ReHo in the right precuneus and left superior MPFC may predict individual therapeutic response for MCT in patients with schizophrenia.

Involuntary Autobiographical Memories in Schizophrenia: Characteristics and Conditions of Elicitation

Involuntary autobiographical memories are mental representations of personally experienced past events that come to mind spontaneously, with no preceding attempt to recall them. They have been showed to be more frequent and more emotional in the psychosis continuum. Although schizophrenia is strongly associated with thought disorders, including cognitive intrusions of thought, images, semantic knowledge, research on patients' involuntary autobiographical memories is limited. We undertook two studies to compare involuntary and voluntary remembering in schizophrenia and the conditions in which involuntary memories occurs in those patients, both in daily life (n = 40), using a diary method, and in an experimental context (n = 50). Overall, results showed that the conditions of elicitation of involuntary memories differ in patients, as patients were more sensitive to memory triggers, especially internal triggers, in comparison to controls. Relatedly, patients' involuntary memories-mostly related to mundane events with low emotional load-were experienced more frequently. Although patients' involuntary and voluntary memories were less clear, more poorly contextualized and associated with a lower belief in occurrence than those of controls, patients considered them as more central to the self, in comparison to controls. The results are discussed in relation to patients' self-reflective impairments.

Metacognitive Training Modulates Default-Mode Network Homogeneity During 8-Week Olanzapine Treatment in Patients With Schizophrenia

BACKGROUND

Previous studies have revealed the efficacy of metacognitive training for schizophrenia. However, the underlying mechanisms of metacognitive training on brain function alterations, including the default-mode network (DMN), remain unknown. The present study explored treatment effects of metacognitive training on functional connectivity of the brain regions in the DMN.

METHODS

Forty-one patients with schizophrenia and 20 healthy controls were scanned using resting-state functional magnetic resonance imaging. Patients were randomly assigned to drug plus psychotherapy (DPP) and drug therapy (DT) groups. The DPP group received olanzapine and metacognitive training, and the DT group received only olanzapine for 8 weeks. Network homogeneity (NH) was applied to analyze the imaging data, and pattern classification techniques were applied to test whether abnormal NH deficits at baseline might be used to discriminate patients from healthy controls. Abnormal NH in predicting treatment response was also examined in each patient group.

RESULTS

Compared with healthy controls, patients at baseline showed decreased NH in the bilateral ventral medial prefrontal cortex (MPFC), right posterior cingulate cortex (PCC)/precuneus, and bilateral precuneus and increased NH in the right cerebellum Crus II and bilateral superior MPFC. NH values in the right PCC/precuneus increased in the DPP group after 8 weeks of treatment, whereas no substantial difference in NH value was observed in the DT group. Support vector machine analyses showed that the accuracy, sensitivity, and specificity for distinguishing patients from healthy controls were more than 0.7 in the NH values of the right PCC/precuneus, bilateral ventral MPFC, bilateral superior MPFC, and bilateral precuneus regions. Support vector regression analyses showed that high NH levels at baseline in the bilateral superior MPFC could predict symptomatic improvement of positive and negative syndrome scale (PANSS) after 8 weeks of DPP treatment. No correlations were found between alterations in the NH values and changes in the PANSS scores/cognition parameters in the patients.

CONCLUSION

This study provides evidence that metacognitive training is related to the modulation of DMN homogeneity in schizophrenia.

Metacognitive function and fragmentation in schizophrenia: Relationship to cognition, self-experience and developing treatments

Bleuler suggested that fragmentation of thought, emotion and volition were the unifying feature of the disorders he termed schizophrenia. In this paper we review research seeking to measure some of the aspects of fragmentation related to the experience of the self and others described by Bleuler. We focus on work which uses the concept of metacognition to characterize and quantify alterations or decrements in the processes by which fragments or pieces of information are integrated into a coherent sense of self and others. We describe the rationale and support for one method for quantifying metacognition and its potential to study the fragmentation of a person's sense of themselves, others and the relative place of themselves and others in the larger human community. We summarize research using that method which suggests that deficits in metacognition commonly occur in schizophrenia and are related to basic neurobiological indices of brain functioning. We also present findings indicating that the capacity for metacognition in schizophrenia is positively related to a broad range of aspects of psychological and social functioning when measured concurrently and prospectively. Finally, we discuss the evolution and study of one therapy that targets metacognitive capacity, Metacognitive Reflection and Insight Therapy (MERIT) and its potential to treat fragmentation and promote recovery.

Individuals at high risk for psychosis experience more childhood trauma, life events and social support deficit in comparison to healthy controls

Evidence for psychological risk factors on prodromal state of psychosis remained limited and inconsistent. This study aimed to investigate childhood trauma, life events and social support in subjects with high risk for psychosis (HR), first episode psychosis with schizophrenia (FEP) and healthy control (HC). In the study, 56 FEP, 83 HR and 61 HC underwent face-to-face clinical interview and psychological assessment, including Childhood Trauma Questionnaire (CTQ), Life Events Scale (LES) and Perceived Social Support Scale (PSSS). The results showed that in univariate analysis, HR individuals had more childhood trauma, more recent life events and less social support than HC group, and these findings were also supported by ANCOVA analysis except for the results related to social support after taking age, education, marital and employment status as covariates. Logistic regression analysis revealed that HR group was significantly associated with more childhood trauma, poorer overall function and unmarried state than HC group after controlling the interfering factors. HR group was similar with FEP group in these assessments. In conclusion, HR individuals experienced more childhood trauma, life events and social support deficit than HC group, which may be risk factors of conversion to psychosis. Further explorations are warranted to develop optimal psychosocial interventions.

Metacognition in schizophrenia disorders: Comparisons with community controls and bipolar disorder: Replication with a Spanish language Chilean sample

Metacognition refers to the activities which allow for the availability of a sense of oneself and others in the moment. Research mostly in North America with English-speaking samples has suggested that metacognitive deficits are present in schizophrenia and are closely tied to negative symptoms. Thus, replication is needed in other cultures and groups. The present study accordingly sought to replicate these findings in a Spanish speaking sample from Chile. Metacognition and symptoms were assessed among 26 patients with schizophrenia, 26 with bipolar disorder and 36 community members without serious mental illness. ANCOVA controlling for age and education revealed that the schizophrenia group had greater levels of metacognitive deficits than the bipolar disorder and community control groups. Differences in metacognition between the clinical groups persisted after controlling for symptom levels. Spearman correlations revealed a unique pattern of associations of metacognition with negative and cognitive symptoms. Results largely support previous findings and provide added evidence of the metacognitive deficits present in schizophrenia and the link to outcome cross culturally. Implications for developing metacognitively oriented interventions are discussed.

Metacognitive Reflection and Insight Therapy for Early Psychosis: A preliminary study of a novel integrative psychotherapy

Poor insight impedes treatment in early phase psychosis (EPP). This manuscript outlines preliminary findings of an investigation of the novel metacognitively oriented integrative psychotherapy, Metacognitive Reflection and Insight Therapy, for individuals with early phase psychosis (MERIT-EP). Twenty adults with EPP and poor insight were randomized to either six months of MERIT-EP or treatment as usual (TAU). Therapists were trained and therapy was successfully delivered under routine, outpatient conditions. Insight, assessed before and after treatment, revealed significant improvement for the MERIT-EP, but not TAU, group. These results suggest MERIT-EP is feasible to deliver, accepted by patients, and leads to clinically significant improvements in insight.

Metacognitive profiles in schizophrenia and bipolar disorder: Comparisons with healthy controls and correlations with negative symptoms

While deficits in metacognition, or the ability to notice and reflect upon mental states has been observed in schizophrenia and linked with poorer concurrent and future function, it is unknown whether these deficits are unique to schizophrenia. Accordingly, this study assessed metacognition using the Metacognitive Assessment Scale-Abbreviated (MAS-A) and the Metacognitions Questionnaire- 30 (MCQ-30) among 26 adults with schizophrenia, 23 with bipolar disorder and 23 healthy controls. Symptom levels of the psychiatric groups were assessed with the Brief Psychiatric Rating Scale. ANCOVA controlling for age and education revealed that the schizophrenia group had lower scores on the MAS-A total and its subscales compared to the bipolar group and healthy controls. The bipolar disorder group also had lower MAS-A scores than the healthy control group. No group differences were found for the MCQ-30. Examination of symptom correlates revealed MAS-A scores were most commonly related to negative symptoms in both clinical groups. The total score and need for control subscale of MCQ-30 was related to total symptomatology and positive symptoms in patients with bipolar disorder. Correlations between the two measures of metacognition revealed that higher MAS-A scores were significantly related to lower scores on the Need to Control Thoughts MCQ-30 subscale.

Individual Psychotherapy and Changes in Self-Experience in Schizophrenia: A Qualitative Comparison of Patients in Metacognitively Focused and Supportive Psychotherapy

OBJECTIVE

Deficits in metacognition, or the ability to form complex ideas about self and others, may be a root cause of dysfunction in schizophrenia. Accordingly, forms of psychotherapy have been proposed to address metacognitive deficits. This study explored whether metacognitively focused individual psychotherapy can affect self-experience by conducting narrative interviews of patients with a schizophrenia spectrum disorder enrolled in either metacognitively oriented psychotherapy (n = 12) or supportive psychotherapy (n = 13) in a naturalistic setting.

METHOD

Participants in both groups completed a narrative interview consisting of questions that focused on perceptions and process of psychotherapy and its impact on outcomes. Interviews were audiotaped, transcribed, and coded using an inductive process informed by grounded theory.

RESULTS

Qualitative analyses revealed all participants reported psychotherapy led to improvements in self-esteem and the ability to think more clearly and set meaningful goals. The group receiving metacognitively oriented therapy, in contrast to those receiving supportive therapy, reported being able to integrate their current experiences into the larger narratives of their lives and an increased experience of sense of agency and the ability to understand and manage pain.

CONCLUSIONS

Results provide evidence that metacognitively oriented psychotherapy may promote subjective forms of recovery.
