Impaired self-reflection in psychiatric disorders among adults: a proposal for the existence of a network of semi independent functions

The effect of physical exercises program on social functioning, alexithymia, and sense of coherence among patients with bipolar disorders: A randomized control trial

BACKGROUND

Despite evidence that physical exercises have been helpful in the treatment of various psychiatric disorders, it is unclear whether these data can be generalized to bipolar disorder. The use of physical exercises is challenging and hopeful among patients with bipolar disorders. Few studies have examined the efficacy of physical exercise for patients with bipolar disorders.

OBJECTIVE

Investigate the effect of applying physical exercises program on social functioning, alexithymia, and sense of coherence among patients with bipolar disorders.

METHODS

This study followed a randomized control trial design "pre and post-test." Patients were randomly allocated to intervention (n = 25) and control groups (Waiting list) (n = 25). The Social Functioning Scale, Toronto Alexithymia Scale, and Sense of Coherence scales were applied in the study. Pre-test and post-tests were administered to investigate the effect of applying the physical exercises program between December 2022 to March 2023.

RESULTS

A statistically significant increase in the mean sense of coherence and social functioning scores among the study group. Mean alexithymia scores were significantly decreased among the study group between pre, immediately after, and after a three-month follow-up period.

CONCLUSION

Physical exercises are an adjunctive treatment modality that is helpful for patients with bipolar disorders. Nurse educators and service providers should reconsider the physical health care requirements for patients with bipolar disorders to equip them to manage the common comorbidities in people with mental illness.

Experiencing hallucinations in daily life: The role of metacognition

BACKGROUND

Hallucinations have been linked to failures in metacognitive reflection suggesting an association between hallucinations and overestimation of performance, although the cross-sectional findings are inconsistent. This inconsistency may relate to the fluctuating hallucinatory experiences that are not captured in cross-sectional studies. Ecological Momentary Assessment (EMA) captures in-the-moment experiences over time so can identify causal relationships between variables such as the associations between metacognition and hallucinatory experience in daily life and overcome problems in cross-sectional designs.

METHODS

Participants (N = 41) experiencing daily hallucinations completed baseline questionnaires and smartphone surveys 7 times per day for 14 days. They were prompted to identify a task they would complete in the next 4 h and to make metacognitive predictions around the likelihood of completing the task, the difficulty of the task, and how well they would complete it (standard of completion).

RESULTS

76 % finished the 14-days of assessment with an average of 42.2 % survey completion. Less accurate metacognition was associated with more hallucinations, but less accurate likelihood and standard of completion was associated with fewer hallucinations. Using a cross-lagged analysis, metacognitive predictions around the likelihood of completion (p < .001) and standard of completion (p = .01) predicted hallucination intensity at the following timepoint, and metacognitive predictions regarding likelihood of completion (p = .02) predicted hallucination control at the following timepoint.

DISCUSSION

Interventions that aim to improve metacognitive ability in-the-moment may serve to reduce the intensity and increase the control of hallucinations.

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.

Mental Pain Correlates with Mind Wandering, Self-Reflection, and Insight in Individuals with Psychotic Disorders: A Cross-Sectional Study

Understanding the cognitive processes that contribute to mental pain in individuals with psychotic disorders is important for refining therapeutic strategies and improving patient outcomes. This study investigated the potential relationship between mental pain, mind wandering, and self-reflection and insight in individuals diagnosed with psychotic disorders. We included individuals diagnosed with a 'schizophrenia spectrum disorder' according to DSM-5 criteria. Patients in the study were between 18 and 65 years old, clinically stable, and able to provide informed consent. A total of 34 participants, comprising 25 males and 9 females with an average age of 41.5 years (SD 11.5) were evaluated. The Psychache Scale (PAS), the Mind Wandering Deliberate and Spontaneous Scale (MWDS), and the Self-Reflection and Insight Scale (SRIS) were administered. Statistical analyses involved Spearman's rho correlations, controlled for potential confounders with partial correlations, and mediation and moderation analyses to understand the indirect effects of MWDS and SRIS on PAS and their potential interplay. Key findings revealed direct correlations between PAS and MWDS and inverse correlations between PAS and SRIS. The mediation effects on the relationship between the predictors and PAS ranged from 9.22% to 49.8%. The largest statistically significant mediation effect was observed with the SRIS-I subscale, suggesting that the self-reflection and insight component may play a role in the impact of mind wandering on mental pain. No evidence was found to suggest that any of the variables could function as relationship moderators for PAS. The results underscore the likely benefits of interventions aimed at reducing mind wandering and enhancing self-reflection in psychotic patients (e.g., metacognitive therapy, mindfulness). Further research will be essential to elucidate the underlying mechanisms.

Agency in avoidant personality disorder: a narrative review

Objectives

Avoidant personality disorder (AvPD) is a highly prevalent personality disorder, especially in clinical settings, yet scarcely researched. People diagnosed with AvPD have severe impairments in functioning and suffer greatly, yet we still lack meta-analytic evidence for therapy and only a few RCTs are conducted. Patient factors are the most important for outcome in therapy, in general. Lack of agency might be a core deficit in people diagnosed with AvPD. Their conditions might be improved if we understand their agency better. We review previous research regarding psychological mechanisms and interpersonal relationships that facilitate or hinder agency in AvPD in daily life and psychotherapy.

Methods

Summarizing original literature in a narrative review with reflexive thematic analysis.

Results

People diagnosed with AvPD seem to have significant impairments in their sense of agency due to a lack of emotional awareness, an overweight of inhibiting vs. activating emotions, and difficulties regulating emotions. Difficulties also seem related to high levels of attachment avoidance and fear, creating strong ambivalence in social needs, in addition to a strong tendency to subordinate to others. A weak sense of self with a poor narrative, self-doubt, and harsh self-critique makes a reflexive and intentional stand increasingly difficult for these people.

Conclusion

This review gives a clinically meaningful understanding of core strengths and deficits in the personality functioning of AvPD that can help clinicians map out important therapeutic work, identify barriers to client-agency in therapy, and work through relational difficulties in the therapeutic alliance.

The development of narrative identity in the psychodynamic treatment of avoidant personality disorder: A case study

Avoidant personality disorder (AvPD) is characterized by feelings of shyness, inadequacy, and restraint in intimate relationships and has been associated with a disturbance in narrative identity, which is the internalized and evolving story of past, present, and future experiences. Study findings have indicated that an improvement in overall mental health through psychotherapy may increase narrative identity. However, there is a lack of studies incorporating not only the examination of narrative identity development before and after psychotherapy but also within psychotherapy sessions. This case study examined the development of narrative identity in short-term psychodynamic psychotherapy treatment of a patient with AvPD, using therapy transcripts and life narrative interviews before, after, and 6 months following treatment termination. Narrative identity development was assessed in terms of agency, communion fulfillment, and coherence. Results showed that the patient’s agency and coherence increased over the course of therapy, whereas communion fulfillment decreased. At the six-month follow-up, agency and communion fulfillment increased, whereas coherence remained stable. The results of this case study suggest that the patient’s sense of narrative agency and ability to narrate coherently improved after undergoing short-term psychodynamic therapy. The decrease of communion fulfillment during psychotherapy and later increase after termination suggests that the patient became more aware of conflictual patterns in their relationships, therefore realizing that their wishes and desires were not being fulfilled in their current relationships. This case study displays the possible impact short-term psychodynamic therapy may have by helping patients with AvPD develop a narrative identity.

Verbal manifestations of metacognitive and social cognitive operations in patients with schizophrenia who received metacognitive training

The study investigates with inductive content analysis the verbal manifestations of schizophrenia patients, their utterances within the theory of mind modules of Metacognitive Training. Participants were recruited via psychiatrists’ verbal referrals. Four small groups were formed, two of which consented to the audio recording of their sessions. Only the sessions of these two groups of five and four patients respectively were investigated. As two participants dropped out, the verbalisations of seven participants were eventually analysed. All patients had schizophrenia diagnosis (mean age: 43 years, male: two, female: five). The verbal contents were transcribed, then two independent coders did the categorisation of the content; investigator triangulation ensured the reliability and validity of the study. As a result, a five-level hierarchy of cognitive operations was revealed in a bottom-up way. Patients attempted to interpret not only facial expressions but expressive movements, too, during emotion recognition. When deducing the state of others, patients sought contextual information; moreover, the burden of the illness and stigmatisation became easy to share. No signs of awareness of the consequences of the inferred states were found regarding future adjustment. Our hierarchical structure was consistent with related literature, and the specificities of cognitive operations of participants were also revealed.

The Cognitive, Ecological, and Developmental Origins of Self-Disturbance in Borderline Personality Disorder

Self-disturbance is recognized as a key symptom of Borderline Personality Disorder (BPD). Although it is the source of significant distress and significant costs to society, it is still poorly specified. In addition, current research and models on the etiology of BPD do not provide sufficient evidence or predictions about who is at risk of developing BPD and self-disturbance, and why. The aim of this review is to lay the foundations of a new model inspired by recent developments at the intersection of social cognition, behavioral ecology, and developmental biology. We argue that the sense of agency is an important dimension to consider when characterizing self-disturbances in BPD. Second, we address the poorly characterized relation between self-disturbances and adverse life conditions encountered early in life. We highlight the potential relevance of Life-History Theory-a major framework in evolutionary developmental biology-to make sense of this association. We put forward the idea that the effect of early life adversity on BPD symptomatology depends on the way individuals trade their limited resources between competing biological functions during development.

Deficits in access consciousness, integrative function, and consequent autonoetic thinking in schizophrenia

Alterations within consciousness in schizophrenia can be evidenced by impediments in self-awareness and loss of agency. Ned Block's definition of access consciousness is applied in order to further delineate cognitive deficits involving reflective thought and autonoetic thinking in persons with schizophrenia. Current theories on the nature and functioning of consciousness are discussed, which include Global Workspace Theory and metarepresentational characterizations. These describe a recursive, integrative quality to consciousness, contributed to by the functions of access consciousness, that is relevant in examining cognitive deficits in schizophrenia. The integrative deficit that is described as operating in conscious process involves a failure to incorporate prior outputs from a separate cognitive task and integrate these into a novel working schema. The alterations in access consciousness in persons with schizophrenia appear to be a consequence of disrupted integrative cognitive functions. An anteceding problem with cortical circuits involving integrative functions related to access consciousness is therefore hypothesized to manifest as subsequent cognitive dysfunction that leads to symptoms of schizophrenia. Constitutive failures to integrate information in schizophrenia could lead to an inability to create experiential unity and manage content in autonoetic consciousness. Some of the aberrant reasoning manifested by persons with schizophrenia, including problems with hierarchical relational reasoning, model-based-learning, J-con, ipseity, and source monitoring, could also reflect alterations in access consciousness, and their investigation offers additional approaches for scientific inquiry.

Metacognition, social cognition, and mentalizing in psychosis: are these distinct constructs when it comes to subjective experience or are we just splitting hairs?

Research using the integrated model of metacognition has suggested that the construct of metacognition could quantify the spectrum of activities that, if impaired, might cause many of the subjective disturbances found in psychosis. Research on social cognition and mentalizing in psychosis, however, has also pointed to underlying deficits in how persons make sense of their experience of themselves and others. To explore the question of whether metacognitive research in psychosis offers unique insight in the midst of these other two emerging fields, we have offered a review of the constructs and research from each field. Following that summary, we discuss ways in which research on metacognition may be distinguished from research on social cognition and mentalizing in three broad categories: (1) experimental procedures, (2) theoretical advances, and (3) clinical applications or indicated interventions. In terms of its research methods, we will describe how metacognition makes a unique contribution to understanding disturbances in how persons make sense of and interpret their own experiences within the flow of life. We will next discuss how metacognitive research in psychosis uniquely describes an architecture which when compromised - as often occurs in psychosis - results in the loss of persons' sense of purpose, possibilities, place in the world and cohesiveness of self. Turning to clinical issues, we explore how metacognitive research offers an operational model of the architecture which if repaired or restored should promote the recovery of a coherent sense of self and others in psychosis. Finally, we discuss the concrete implications of this for recovery-oriented treatment for psychosis as well as the need for further research on the commonalities of these approaches.

Incorporating narrative repair in the treatment of avoidant personality disorders: A case in point

Avoidant personality disorder (AvPD) is characterized by multiple struggles, including shyness, feelings of inadequacy, and hypersensitivity to interpersonal judgments. Research indicates that people with AvPD also show disturbances in narrative identity, which is an internal and evolving story created about the personal past, present, and presumed future. Here, the novel Guide for Narrative Repair (GNaR) recently developed by (Thomsen et al., 2020) is introduced as a potentially useful tool to help people with AvPD in crafting more adaptive narrative identities. The guide is brought to life via a case study analysis of Adam, a male outpatient suffering from AvPD. Consistent with the GNaR, disturbances in Adam's storied self are brought to light and ways to facilitate his narrative repair are proposed. We conclude with implications related to the case as well as the potential narrative turn in AvPD treatment.

Associations between Cognitive Concepts of Self and Emotional Facial Expressions with an Emphasis on Emotion Awareness

Recognising our own and others’ emotions is vital for healthy social development. The aim of the current study was to determine how emotions related to the self or to another influence behavioural expressions of emotion. Facial electromyography (EMG) was used to record spontaneous facial muscle activity in nineteen participants while they passively viewed negative, positive and neutral emotional pictures during three blocks of referential instructions. Each participant imagined themself, another person or no one experiencing the emotional scenario, with the priming words “You”, “Him” or “None” presented before each picture for the respective block of instructions. Emotion awareness (EA) was also recorded using the TAS-20 alexithymia questionnaire. Corrugator supercilii (cs) muscle activity increased significantly between 500 and 1000 ms post stimulus onset during negative and neutral picture presentations, regardless of ownership. Independent of emotion, cs activity was greatest during the “no one” task and lowest during the “self” task from less than 250 to 1000 ms. Interestingly, the degree of cs activation during referential tasks was further modulated by EA. Low EA corresponded to significantly stronger cs activity overall compared with high EA, and this effect was even more pronounced during the “no one” task. The findings suggest that cognitive processes related to the perception of emotion ownership can influence spontaneous facial muscle activity, but that a greater degree of integration between higher cognitive and lower affective levels of information may interrupt or suppress these behavioural expressions of emotion.

Meaning in Life in Long-Term Recovery in First-Episode Psychosis: An Interpretative Phenomenological Analysis

Background: Meaning in Life (MIL) is a central aspect of service user defined personal recovery in mental health. It is unclear whether current knowledge regarding MIL is applicable to the lives of those who have experienced psychosis. As it was not possible to locate any study examining service user perspectives on MIL in first-episode psychosis (FEP), conducting in-depth qualitative research in this area offers an opportunity to develop a conceptualisation of MIL that may be transferable to the broad psychosis spectrum. Aim: The aim of the study was to explore how people find, develop, and maintain MIL approximately 21 years after their FEP diagnosis. Materials and Methods: The study aim was addressed using Interpretative Phenomenological Analysis (IPA). Participants were members of an epidemiologically complete FEP incidence cohort in Ireland. Purposive maximum variation sampling enabled the recruitment of a sample balanced across remission status, age at time of FEP onset, and gender. Semi-structured interviews were conducted circa 21 years post FEP with 16 participants. Data analysis was guided by IPA procedures. Results: Participants experienced MIL as awareness of connectedness to context - the interrelated conditions they existed in (their relationships with the self, others, systems, the environment, and time). Awareness of connectedness to context occurred in five main ways: Being myself - de-othering and authenticity (Enacting identity); Becoming significant where the self is witnessed (Belonging in life); Generating meaning within and beyond systems (Independence); Shaping and being shaped by life (Agency and patiency); and Integrating different perspectives of time (Reconciling temporality). Conclusions: Findings offer the first in-depth understanding of how people diagnosed with a FEP experience MIL in mid-later life recovery. Current tripartite MIL theories do not fully represent the array of MIL perspectives articulated by our participants. MIL concepts developed are potential areas for intervention for mental health services seeking to implement the recovery approach. Findings can be used to foster optimism among service users and their supporters for MIL attainment in psychosis and offer guidance for education, clinical practice, policy, and future research.

Beyond the cognitive insight paradox: Self-reflectivity moderates the relationship between depressive symptoms and general psychological distress in psychosis

BACKGROUND

People with psychosis experience significant emotional burden and distress associated with the symptomatic consequences of their mental disorder, thus difficulting their recovery. Several studies have found self-reflectivity, a dimension of cognitive insight, to be associated with effects which taken together may seem paradoxical, by predicting less psychotic symptom severity but more depression. To elucidate this issue, we examined the influence of psychotic symptoms, depressive symptoms, and self-reflectivity, on psychological distress. Further, we tested whether self-reflectivity moderated the relationship between depressive symptoms and psychological distress.

METHODS

Seventy-six outpatients with psychotic-spectrum disorders were assessed using measures of psychotic symptoms, depressive symptoms, cognitive insight (i.e., self-reflectivity, self-certainty) and psychological distress.

RESULTS

A regression model revealed that depressive, positive symptoms and the interaction between depressive symptoms and self-reflectivity had a significant effect on psychological distress. The moderation analysis showed that higher levels of self-reflectivity were related to less psychological distress associated with depressive mood.

CONCLUSIONS

The role of self-reflectivity on depression and distress may be more complex than a direct effect. Interventions targeted to improve metacognition by enhancing self-reflectivity might be important for lowering the psychological distress associated with depressive symptoms in people with psychosis.

Language and the Symptoms of Mental Illness Connection via Abstract Representations of the Self and the World

The aim of the present study is to provide additional knowledge about the mediatory processes through which language contributes to the symptoms of mental illness. Although recent studies have provided insight about the relationship between language and the indicators of mental illness, the role of intervening variables in this connection has been ignored. The present investigation tested a structural equation model in which the need for the absolute truth about self and worry mediated the relationship of the gap between inner psychological experience and language with anxiety and depression. The results have provided support for the model and showed that the gap predicts both the need for absolute truth and worry which, in turn, predict the levels of anxiety and depression. The results have been discussed in the light of previous research, and implications for future research have also been considered.

Neuro-cognitive correlates of alexithymia in patients with circumscribed prefrontal cortex damage

Alexithymia has been extensively reported in studies of psychiatric patients. However, little attention has been paid regarding its occurrence in the context of patients with circumscribed prefrontal cortex lesions. Moreover, the neuro-cognitive impairments that lead to alexithymia remain unclear and limited numbers of studies have addressed these issues. The authors investigated the impact of prefrontal cortex lesions on alexithymia and its neuro-cognitive correlates in a population of 20 patients with focal frontal lesions, 10 patients with parietal lesions and 34 matched control participants. Alexithymia was screened using the Toronto Alexithymia Scale (TAS-20) and executive functions were assessed using a large battery of executive tasks that address inhibition, flexibility and the planning process. Results showed that patients with prefrontal cortex damage showed significantly increased difficulty in facets of identifying feelings (DIF) and externally oriented thinking (EOT) on TAS-20, compared to parietal patients and control participants. Moreover, both correlation and regression analysis revealed that higher alexithymia levels on the three facets of TAS-20 were consistently but differentially associated with impairment in inhibition, flexibility and planning tasks for frontal patients and both control groups. These findings provide clinical evidence of the implication of prefrontal cortex damage and executive control in alexithymia. Our results were also discussed in the light of the cognitive appraisal concept as a mechanism involved in emotion episode processing. This study suggests that increased neuropsychological attention should be directed to the relation between the neuro-cognitive model of executive functions and cognitive appraisal theory in processing emotion.

Self-defining Memories Predict Engagement in Structured Activity in First Episode Psychosis, Independent of Neurocognition and Metacognition

BACKGROUND

Self-defining memories (SDMs) are vivid personal memories, related to narrative identity. Individuals with schizophrenia report less specific, more negative, and extract less meaning from these memories compared to control groups. SDMs have been shown to be predicted by neurocognition, associated with metacognition, and linked to goal outcomes in healthy controls. As neurocognition and metacognition are known predictors of poor functioning in psychosis, SDMs may also be a predictor. No study has assessed the relationship to functioning or pattern of SDMs in first episode psychosis (FEP).

METHODS

This was a cross-sectional study involving 71 individuals with FEP and 57 healthy controls who completed an SDM questionnaire. FEP participants completed measures of neurocognition, metacognition (Metacognitive Assessment Interview), functional capacity (The University of California, San Diego [UCSD] Performance-Based Skills Assessment), and functional outcome (Time-Use Survey).

RESULTS

SDMs reported by individuals with FEP were less integrated compared to healthy controls. Within the FEP sample, holding less specific memories was associated with engagement in significantly fewer hours of structured activity per week and specificity of SDMs mediated the relationship between neurocognition and functional outcome, independent of metacognition.

CONCLUSION

This is the first study to assess SDMs in FEP and to explore the important role of SDMs on clinical outcomes, compared to healthy controls. This study suggests that elaborating on specific SDMs is a valid therapeutic target and may be considered a tool to improve daily functioning in FEP.

Metacognitive Interpersonal Therapy in group (MIT-G) for young adults with personality disorders: A pilot randomized controlled trial

Young adults with personality disorders (PD) other than borderline are in urgent need of validated treatments to help them in managing important life transitions. Therapeutic interventions focused upon social and interpersonal difficulties may facilitate these individuals in maximizing opportunities for employment, forming stable romantic relationships, and belong to social groups. It is also important that they are offered evidence-based, first-line time-limited treatments in order to maximize effectiveness and reduce costs. We developed a 16-session programme of group-based Metacognitive Interpersonal Therapy (MIT-G) including psychoeducation on the main interpersonal motives, an experiential component enabling practice of awareness of mental states; and use of mentalistic knowledge for purposeful problem-solving. We report a feasibility, acceptability, and clinical significance randomized clinical trial. Participants meeting inclusion criteria were randomized to receive MIT-G (n = 10) or waiting list+TAU (n = 10). Dropout rate was low and session attendance high (92.19%). Participants in the MIT-G arm had symptomatic and functional improvements consistent with large effect sizes. In the MIT-G arm similarly large effects were noted for increased capacity to understand mental states and regulate social interactions using mentalistic knowledge. Results were sustained at follow-up. Our findings suggest potential for applying MIT-G in larger samples to further test its effectiveness in reducing PD-related symptoms and problematic social functioning.

Alexithymia predicts poorer social and everyday functioning in schizophrenia and bipolar disorder

Alexithymia, or the inability to identify and describe one's emotions, is significantly higher in bipolar disorder (BD) and schizophrenia (SZ), compared to healthy controls (HC). Alexithymia has also been observed to predict psychosocial functioning in SZ. We investigated whether alexithymia predicted social and everyday functioning in BD, as well as transdiagnostically in HC, BD, and SZ patients. 56 BD, 45 SZ, and 50 HC were administered and compared on tests measuring neurocognition, social cognition, functioning and alexithymia. We conducted linear regressions assessing whether alexithymia predicted functional outcomes in BD. Next, we conducted hierarchical stepwise linear regressions investigating the predictive ability of neurocognition, social cognition and alexithymia on everyday and social functioning in our overall sample. BD and SZ patients were comparable on most demographics and demonstrated higher alexithymia compared to HCs. In BD, alexithymia predicted social functioning only. In the overall sample, difficulty identifying and describing feelings predicted everyday functioning; difficulty describing feelings predicted social functioning. Results suggest that aspects of alexithymia significantly predict functioning among these psychiatric groups, above and beyond the contributions of previously identified factors such as neurocognition and social cognition. Results may aid in developing proper interventions aimed at improving patients' ability to articulate their feelings.

Three-Year Follow-Up Study Exploring Metacognition and Function in Individuals With First Episode Psychosis

Introduction: Research has demonstrated that functional outcome in psychosis is predicted by factors such as neurocognition, functional capacity, symptoms and, more recently, metacognition. Metacognitive ability has been demonstrated to mediate between neurocognition and functional outcome in First Episode Psychosis (FEP). Whether metacognition also predicts longer-term recovery in first episode psychosis is unknown. This study assessed whether neurocognition, functional capacity and metacognitive ability in FEP predicted functional outcome three years later. Methods: Eighty individuals with First Episode Psychosis were re-contacted after an average 3 years (range: 26-45 month follow-up) from baseline. Twenty-six participants (33%) completed completed measures of neurocognition, metacognition, functional capacity, functional outcome (hours spent in structured activity per week) and psychopathology at baseline and at follow-up. Results: Individual regression analyses demonstrated neurocognition, functional capacity, and metacognitive ability at baseline significantly predicted functional outcome at three years. However, when baseline functional outcome was controlled, only metacognitive ability was a significant predictor of change in functional outcome from baseline to follow-up, p < 0.001. This model explained 72% (adjusted r ² = 0.69) of the variance in functional outcome at follow-up. Negative symptoms did not change the model. Discussion: This study demonstrated that better metacognitive ability significantly predicted improvement in functioning in FEP across a 3-year period. This highlights the potential value of clinical interventions that focus on improving metacognitive ability at first point of illness to maximize recovery.

Cognitive mechanisms of alexithymia in schizophrenia: Investigating the role of basic neurocognitive functioning and cognitive biases

Alexithymia is an important but poorly understood emotional deficit in schizophrenia. We aimed at investigating the role of basic cognitive functions, cognitive biases, and symptom severity in alexithymia among patients with schizophrenia. Sixty patients (31 females) with schizophrenia were assessed with standardized clinical interviews for symptom severity. Cognitive functioning was assessed with neuropsychological tests. A self-report scale (Davos Assessment of Cognitive Biases, DACOBS), as well as two experimental tasks assessing jumping to conclusions (the Fish task) and source monitoring (Action memory task), were used to investigate cognitive biases. Alexithymia was assessed with the Toronto Alexithymia Scale (TAS-20). Alexithymia was related to the severity of hallucinations but not delusions. Patients with a lifetime history of more psychotic symptoms had higher alexithymia. Alexithymia has broad relationships with different cognitive biases, especially in the self-reported measure. These relationships were not affected by neurocognition and symtpoms severity. In particular, difficulties in identification of feelings were related to various cognitive biases. Dysfunctional information processing can thus be considered as potential psychological correlates of alexithymia. The theoretical and clinical implications of our findings are discussed.

Metacognitive interpersonal therapy in group: a feasibility study

Patients with personality disorders (PDs) other than borderline, with prominent features of social inhibition and over-regulation of emotions, are in need of specialized treatments. Individuals present with poor metacognition, that is the capacity to understand mental states and use psychological knowledge for the sake of purposeful problem solving; and are guided by maladaptive interpersonal schemas. We developed a short-term group intervention, Metacognitive Interpersonal Therapy in Groups (MIT-G), incorporating psychoeducational and experiential elements, to help these individuals become more aware of their drives when interacting with others; and to help them adopt more flexible behaviors via improvements in metacognition. We present results of an effectiveness study, evaluating whether we could replicate the initial positive results of our first pilot randomized controlled trial. Seventeen young adults outpatients with personality disorders were included in the 16 session program. Effect sizes were calculated for change from baseline to treatment end for the primary outcome, symptoms and functioning (Clinical Outcomes in Routine Evaluation Outcome Measure) and then for one putative mechanism of change - metacognition. Emotional dysregulation and alexithymia were also assessed. Qualitative evaluations of the acceptability and subjective impact of the treatment were also performed. MIT-G was acceptable to participants. There were medium to large magnitude changes from pre- to post- treatment on wellbeing, emotion dysregulation, alexithymia and metacognition. These gains were maintained at follow-up. There was evidence of clinically significant change on key variables. MITG appears acceptable to patients, as evidenced by the absence of drop-out from treatment. In light of the positive outcomes of this study and the expanding evidence base, MIT-G is a candidate for dissemination and investigations in larger trials as a possible effective intervention for PDs characterized by tendencies to overcontrol.

A Disorder by Any Other Name: Metacognition, Schizophrenia, and Diagnostic Practice

Humanistic psychology has made us aware that any understanding of schizophrenia must see persons diagnosed with this condition as whole persons who are making sense of what wellness and recovery mean to them. This has raised questions about what the diagnosis of schizophrenia means and whether the diagnostic label of schizophrenia is helpful when we try to conceptualize the actions and aims of treatment. To examine this issue we propose it is essential to consider what is systematically occuring psychologicaly in recovery when persons experience, interpret and agentically respond to emerging challenges. We then review how the integrated model of metacognition provides a systematic, person-centered, evidence-based approach to understanding psychological processes which impact recovery, and discuss how this guides a form of psychotherapy, metacognitive reflection and insight therapy, which promotes metacognitive abilities and support recovery. We suggest this work indicates that metacognitive capacity is something that can be diagnosed without stigmatizing persons. It can be used to meaningfully inform clinical practice across various theoretical models and offers concrete implications for rehabilitation.

Evidence of disturbances of deep levels of semantic cohesion within personal narratives in schizophrenia

Since initial conceptualizations, schizophrenia has been thought to involve core disturbances in the ability to form complex, integrated ideas. Although this has been studied in terms of formal thought disorder, the level of involvement of altered latent semantic structure is less clear. To explore this question, we compared the personal narratives of adults with schizophrenia (n=200) to those produced by an HIV+ sample (n=55) using selected indices from Coh-Metrix. Coh-Metrix is a software system designed to compute various language usage statistics from transcribed written and spoken language documents. It differs from many other frequency-based systems in that Coh-Metrix measures a wide range of language processes, ranging from basic descriptors (e.g., total words) to indices assessing more sophisticated processes within sentences, between sentences, and across paragraphs (e.g., deep cohesion). Consistent with predictions, the narratives in schizophrenia exhibited less cohesion even after controlling for age and education. Specifically, the schizophrenia group spoke fewer words, demonstrated less connection between ideas and clauses, provided fewer causal/intentional markers, and displayed lower levels of deep cohesion. A classification model using only Coh-Metrix indices found language markers correctly classified participants in nearly three-fourths of cases. These findings suggest a particular pattern of difficulties cohesively connecting thoughts about oneself and the world results in a perceived lack of coherence in schizophrenia. These results are consistent with Bleuler's model of schizophrenia and offer a novel way to understand and measure alterations in thought and speech over time.

A Pragmatic View of Disturbed Self-Reflection in Personality Disorders: Implications for Psychotherapy

Patients with personality disorders suffer from impairment in self-reflective capacities. This is not a matter of making incorrect judgments about self-experience but reflects problems with (a) labeling internal experience consistent with the type and level of bodily arousal, (b) seeing how thoughts and feelings are connected to one another within the flow of daily life, and (c) realizing that one's own ideas about interpersonal relationships are subjective and fallible and not direct perceptions of external reality. The authors offer a discussion and definition of each of these three impairments and then offer suggestions for how to address these impairments in psychotherapy.

The relationship between clinical insight and cognitive and affective empathy in schizophrenia

Background

Schizophrenia is often associated with poor clinical insight (unawareness of mental illness and its symptoms) and deficits in empathy, which are important for social functioning. Cognitive empathy has been linked to clinical insight while affective empathy and its role in insight and pathology have received mixed evidence.

Methods

Instruments assessing symptomatology (Positive and Negative Syndrome Scale; PANSS), clinical insight (Scales to assess awareness of mental disorders; SUMD), and cognitive and affective empathy were administered to 22 participants with first episode and chronic schizophrenia and 21 healthy controls. Self-report, parent-report, and performance based measures were used to assess cognitive and affective empathy (The interpersonal reactivity index; IRI/Reading the Mind in the Eyes Test/Faux Pas) to reduce bias and parse shared variance.

Results

Age of onset, gender, and symptomatology emerged as significant predictors of poor clinical insight. Additionally, the fantasy subscale of the IRI as reported by parents emerged as a positive predictor while the personal distress (parent report) subscale emerged as a negative predictor of awareness into mental illness. There were significant differences on performance-based measures of empathy between the control and schizophrenia groups.

Conclusion

Findings suggest that affective empathy is relatively intact across phases of illness whereas cognitive empathy abilities are compromised and could be targets for psychotherapy intervention.

The neural correlates of self-referential memory encoding and retrieval in schizophrenia

BACKGROUND

Enhanced memory for self-oriented information is known as the self-referential memory (SRM) effect. fMRI studies of the SRM effect have focused almost exclusively on encoding, revealing selective engagement of the medial prefrontal cortex (mPFC) during "self" relative to other processing conditions. Other critical areas for self-processing include ventrolateral prefrontal cortex (vlPFC), temporo-parietal junction (TPJ) and posterior cingulate/precuneus (PCC/PC). Previous behavioral studies show that individuals with schizophrenia fail to benefit from this memory boost. However, the neural correlates of this deficit, at either encoding or retrieval, are unknown.

METHODS

Twenty individuals with schizophrenia and 16 healthy controls completed an event-related fMRI SRM paradigm. During encoding, trait adjectives were judged in terms of structural features ("case" condition), social desirability ("other" condition), or as self-referential ("self" condition). Participants then completed an unexpected recognition test (retrieval phase). We examined BOLD activation during both encoding and retrieval within mPFC, vlPFC, TPJ, and PCC/PC regions-of-interest (ROIs).

RESULTS

During encoding, fMRI data indicated both groups had greater activation during the "self" relative to the "other" condition across ROIs. Controls showed this primarily in mPFC whereas patients showed this in PCC/PC. During retrieval, fMRI data indicated controls showed differentiation across ROIs between "self" and "other" conditions, but patients did not.

CONCLUSIONS

Results suggest regional differences in the neural processing of self-referential information in individuals with schizophrenia, perhaps because representation of the self is not as well established in patients relative to controls. The current study presents novel findings that add to the literature implicating impaired self-oriented processing in schizophrenia.

Association of medial prefrontal resting state functional connectivity and metacognitive capacity in early phase psychosis

Metacognition refers to a range of cognitive processes that allow one to form complex ideas of self and others and to use this information to navigate psychosocial challenges. Several studies in both early-phase and prolonged schizophrenia have demonstrated not only that significant deficits in metacognitive ability are present, but importantly that they are associated with significant functional impairment and decreased quality of life. In spite of the importance of metacognitive impairment in schizophrenia, relatively little is known about the biological substrates that may contribute to this dysfunction. In this study, we examined the relationship between resting state functional connectivity of the medial prefrontal cortex (mPFC), a structure shown in prior voxel-based morphometry studies to be associated with metacognition, with metacognitive function in an early-phase psychosis cohort (n=18). Analyses revealed a positive association of resting state functional connectivity between the mPFC and precuneus and posterior cingulate structures and metacognitive ability. These results provide evidence of disrupted resting state connectivity in structures relevant to metacognitive dysfunction in early-phase psychosis, which may have implications for pathophysiological models of complex cognitive deficits in this illness.

Alexithymia Is Associated with Tinnitus Severity

OBJECTIVE

Alexithymia is considered to be a personality trait with a tendency to express psychological distress in somatic rather than emotional form and, therefore, may play a vital role in somatization. Although, such a propensity can be found in patients suffering from tinnitus, the relationship between alexithymic characteristics and the subjective experience of tinnitus severity remains yet unclear. Our aim was to evaluate which alexithymic characteristics are linked to the subjective experience of tinnitus symptomatology.

METHODS

We evaluated tinnitus severity (Tinnitus Handicap Inventory, THI), alexithymia (20-item Toronto Alexithymia Scale, TAS-20), and depression (Beck Depression Inventory, BDI) in 207 outpatients with tinnitus. Correlation analyses and multiple regression analyses were calculated in order to investigate the relationship between alexithymic characteristics, tinnitus severity, and depression.

RESULTS

Highly significant positive correlations were found between THI total score and TAS-20 total score as well as BDI score. Regarding the TAS-20 subscales, multiple regression analyses showed that only the TAS-20 subscale "difficulty in identifying feelings" (DIF) and the BDI significantly predicted the subjective experience of tinnitus severity. Regarding the THI subscales, only higher scores of the THI subscale "functional" demonstrated an independent moderate association with higher scores for DIF.

CONCLUSION

We found an independent association between the subjective experience of tinnitus severity and alexithymic characteristics, particularly with regard to limitations in the fields of mental, social, and physical functioning because of tinnitus and the difficulty of identifying feelings facet of alexithymia. These findings are conducive to a better understanding of affect regulation that may be important for the psychological adaptation of patients suffering from tinnitus.

Functional abnormalities of the right posterior insula are related to the altered self-experience in schizophrenia

The insula is involved in detecting the salience of internal and external stimuli, and it plays a critical role in psychosis. Previous studies have demonstrated the structural and functional alterations of the insula in schizophrenia. To acquire a full picture of the functional alterations of the insula in schizophrenia, the resting-state fMRI data of 46 patients with schizophrenia and 46 healthy control subjects were collected. We used clustering analysis to divide the insula into three subregions: the dorsal anterior insula (dAI), ventral anterior insula (vAI) and posterior insula (PI). Then, whole-brain functional connectivity analysis was conducted based on these subregions. The results showed that the right dAI and PI in patients exhibited altered functional connections with the primary sensorimotor area. In addition, the right PI of the patients exhibited increased functional correlations with the thalamus. More importantly, the altered functional properties of the right PI were significantly correlated with the severity of the delusion and poor insight in schizophrenia. The results suggested that the right PI might play an important role in self-experience processing in schizophrenia. Accordingly, the right PI should be considered very important in the pathological mechanism of schizophrenia.

Impaired Self-Monitoring of Inner Speech in Schizophrenia Patients with Verbal Hallucinations and in Non-clinical Individuals Prone to Hallucinations

BACKGROUND

Previous research has shown that various memory errors reflecting failure in the self-monitoring of speech were associated with auditory/verbal hallucinations in schizophrenia patients and with proneness to hallucinations in non-clinical individuals.

METHOD

We administered to 57 schizophrenia patients and 60 healthy participants a verbal memory task involving free recall and recognition of lists of words with different structures (high-frequency, low-frequency, and semantically organisable words). Extra-list intrusions in free recall were tallied, and the response bias reflecting tendency to make false recognitions of non-presented words was computed for each list.

RESULTS

In the male patient subsample, extra-list intrusions were positively associated with verbal hallucinations and inversely associated with negative symptoms. In the healthy participants the extra-list intrusions were positively associated with proneness to hallucinations. A liberal response bias in the recognition of the high-frequency words was associated with verbal hallucinations in male patients and with proneness to hallucinations in healthy men. Meanwhile, a conservative response bias for these high-frequency words was associated with negative symptoms in male patients and with social anhedonia in healthy men.

CONCLUSION

Misattribution of inner speech to an external source, reflected by false recollection of familiar material, seems to underlie both clinical and non-clinical hallucinations. Further, both clinical and non-clinical negative symptoms may exert on verbal memory errors an effect opposite to that of hallucinations.

An integrative model of the impairments in insight in schizophrenia: emerging research on causal factors and treatments

INTRODUCTION

Poor insight, or unawareness of some major aspect of mental illness, is a major barrier to wellness when it interferes with persons seeking out treatment or forming their own understanding of the challenges they face. One barrier to addressing impaired insight is the absence of a comprehensive model of how poor insight develops.

AREAS COVERED

To explore this issue we review how poor insight is the result of multiple phenomena which interfere with the construction of narrative accounts of psychiatric challenges, rather than a single social or biological cause. Expert commentary: We propose an integrative model of poor insight in schizophrenia which involves the interaction of symptoms, deficits in neurocognition, social cognition, metacognition, and stigma. Emerging treatments for poor insight including therapies which focus on the development of metacognition are discussed.

A Preliminary Study of the Association Among Metacognition and Resting State EEG in Schizophrenia

Abstract. Metacognition refers to a spectrum of activities that range from the consideration of discrete mental experiences, such as a specific thought or emotion, to the synthesis of discrete perceptions into integrated representations of the self and others as unique agents in the world. Metacognitive deficits have been observed in schizophrenia and linked with a number of behavioral correlates and outcomes. Less is known however about the neural systems associated with such processes. Establishing the link between brain activity and metacognition therefore is an essential next step. Resting state electroencephalography (EEG) provides one possible avenue for investigating this link. EEG studies in schizophrenia suggest that the gamma frequency range may have functional significance and be related to the disturbed information processing often observed in the disorder. In the present investigation, we assessed metacognition among 20 individuals with prolonged schizophrenia using the Metacognition Assessment Scale Abbreviated, who also participated in resting state EEG recording. We hypothesized that gamma activity would be associated with those domains of metacognition that require the most integration to perform, Decentration and Mastery. We then examined the association among gamma power and each metacognitive domain. Additional exploratory analyses were conducted across a spectrum of EEG activity. We found that increased gamma activity at rest was linked with decreased decentration. This suggests that hyperactivity in the gamma range may index disrupted processing and integration, and ultimately the metacognitive processes needed to form complex ideas about oneself and others and to see the world from multiple perspectives. This link provides additional evidence of how the biological roots of schizophrenia may culminate in a disrupted life.

Metacognition in Early Phase Psychosis: Toward Understanding Neural Substrates

Individuals in the early phases of psychotic illness have disturbed metacognitive capacity, which has been linked to a number of poor outcomes. Little is known, however, about the neural systems associated with metacognition in this population. The purpose of this study was to elucidate the neuroanatomical correlates of metacognition. We anticipated that higher levels of metacognition may be dependent upon gray matter density (GMD) of regions within the prefrontal cortex. Examining whole-brain structure in 25 individuals with early phase psychosis, we found positive correlations between increased medial prefrontal cortex and ventral striatum GMD and higher metacognition. These findings represent an important step in understanding the path through which the biological correlates of psychotic illness may culminate into poor metacognition and, ultimately, disrupted functioning. Such a path will serve to validate and promote metacognition as a viable treatment target in early phase psychosis.

Metacognitive capacity as a predictor of insight in first-episode psychosis

Impaired insight is common in the first episode of psychosis (FEP). Although considerable research has examined the factors that are associated with impaired insight in chronic psychosis, less is known about the factors that underlie and sustain poor insight in FEP. Impaired metacognition, or the ability to form integrated representations of self and others, is a promising potential contributor to poor insight in FEP. To explore this possibility, the authors assessed insight and metacognition in 40 individuals with FEP and then examined the relationship between these areas and social cognition domains, neurocognitive domains, and psychotic symptoms. Correlation analyses revealed that improved insight was associated with higher metacognition, better vocabulary and Theory of Mind scores, and fewer symptoms. The domain of metacognitive mastery also predicted clinical insight. Results support the need to develop an integrative therapeutic approach focused on improving metacognition, hence addressing poor insight in FEP.

Brain activation during self- and other-reflection in bipolar disorder with a history of psychosis: Comparison to schizophrenia

Objectives

Reflecting on the self and on others activates specific brain areas and contributes to metacognition and social cognition. The aim of the current study is to investigate brain activation during self- and other-reflection in patients with bipolar disorder (BD). In addition, we examined whether potential abnormal brain activation in BD patients could distinguish BD from patients with schizophrenia (SZ).

Methods

During functional magnetic resonance imaging (fMRI), 17 BD patients, 17 SZ patients and 21 healthy controls (HCs) performed a self-reflection task. The task consisted of sentences divided into three conditions: self-reflection, other-reflection and semantic control.

Results

BD patients showed less activation in the posterior cingulate cortex (PCC) extending to the precuneus during other-reflection compared to HCs (p = 0.028 FWE corrected on cluster-level within the regions of interest). In SZ patients, the level of activation in this area was in between BD patients and HCs, with no significant differences between patients with SZ and BD. There were no group differences in brain activation during self-reflection. Moreover, there was a positive correlation between the PCC/precuneus activation during other-reflection and cognitive insight in SZ patients, but not in BD patients.

Conclusions

BD patients showed less activation in the PCC/precuneus during other-reflection. This may support an account of impaired integration of emotion and memory (evaluation of past and current other-related information) in BD patients. Correlation differences of the PCC/precuneus activation with the cognitive insight in patients with BD and SZ might reflect an important difference between these disorders, which may help to further explore potentially distinguishing markers.

•

We investigated self-reflection and other-reflection in bipolar disorder.

•

Bipolar had less PCC/precuneus activation during other-reflection than controls.

•

PCC/precuneus activation was unrelated to cognitive insight in bipolar patients.

Deficits in Metacognitive Capacity Are Related to Subjective Distress and Heightened Levels of Hyperarousal Symptoms in Adults With Posttraumatic Stress Disorder

Among persons with posttraumatic stress disorder (PTSD), the severity of symptoms and concurrent distress are not fully explained by trauma severity. Interest has consequently arisen in the psychological processes that cause distress and heighten PTSD symptoms. This study accordingly sought to examine whether differences in metacognitive capacity are related to levels of emotional distress, avoidance/numbing, and hyperarousal. Participants were 48 adults with a confirmed diagnosis of PTSD. Comparison groups included 51 adults with HIV and 183 with schizophrenia. Metacognition, emotion recognition, depression, and emotional distress and levels of avoidance/numbing and hyperarousal were assessed concurrently using the Metacognition Assessment Scale-Abbreviated, the Bell Lysaker Emotion Recognition Test, the Beck Depression Inventory, and the Clinician-Administered PTSD Scale. Results revealed that the PTSD group had better ratings of overall metacognitive capacity than the schizophrenia group and specifically poorer levels of metacognitive mastery, or the ability to use metacognitive knowledge to respond to challenges, than the HIV group. Within the PTSD group, poorer metacognitive mastery was linked with greater distress and higher hyperarousal when depression was controlled for statistically. Emotion recognition was not linked with distress or symptom severity. Results are consistent with models in which symptom severity in PTSD is related to the extent to which persons can use knowledge of themselves and others to find ways to respond to distress that match their own unique needs.

A comparison of capacities for social cognition and metacognition in first episode and prolonged depression

There is a growing awareness that social cognition is a valuable construct for understanding the psycho-social disabilities in depressive illness. Numerous studies have linked affective disorders to impairments in social cognition and specifically the processing of discrete emotional stimuli. Only few studies have investigated the relation between the burden of depressive illness and social cognitive ability. To study these issues, we compared a group of first-episode depressed patients with a group of chronically depressed patients (duration >2 years) on a broad array of higher-order social cognitive measures including the metacognition assessment scale abbreviated. Contrary to prediction, deficits in social cognition were roughly equivalent between the two groups and there was no significant link between symptom severity and social cognitive ability. Having moderate to severe major depressive disorder (MDD) could be sufficient to predict the presence of deficits in social cognitive ability.

Creativity measured by divergent thinking is associated with two axes of autistic characteristics

Creativity generally involves the conception of original and valuable ideas, and it plays a key role in scientific achievement. Moreover, individuals with autistic spectrum conditions (ASCs) tend to achieve in scientific fields. Recently, it has been proposed that low empathizing and high systemizing characterize individuals with ASCs. Empathizing is the drive to identify the mental status of other individuals and respond to it with an appropriate emotion; systemizing is the drive to analyze a system. It has been proposed that this higher systemizing underlies the scientific achievement of individuals with ASCs, suggesting the possible positive association between creativity and systemizing. However, previous findings on the association between ASCs and creativity were conflicting. Conversely, previous studies have suggested an association between prosocial traits and creativity, indicating the possible association between empathizing and creativity. Here we investigated the association between creativity measured by divergent thinking (CDT) and empathizing, systemizing, and the discrepancy between systemizing and empathizing, which is called D score. CDT was measured using the S-A creativity test. The individual degree of empathizing (empathizing quotient, EQ) and that of systemizing (systemizing quotient, SQ), and D score was measured via a validated questionnaire (SQ and EQ questionnaires). The results showed that higher CDT was significantly and positively correlated with both the score of EQ and the score of SQ but not with D score. These results suggest that CDT is positively associated with one of the characteristics of ASCs (analytical aspects), while exhibiting a negative association with another (lower social aspects). Therefore, the discrepancy between systemizing and empathizing, which is strongly associated with autistic tendency, was not associated with CDT.

Alexithymia in schizophrenia: associations with neurocognition and emotional distress

While alexithymia, or difficulties identifying and describing affect, has been commonly observed in schizophrenia, little is known about its causes and correlates. To test the hypothesis that deficits in emotion identification and expression result from, or are at least related to, deficits in neurocognition and affective symptoms, we assessed alexithymia using the Toronto Alexithymia Scale (TAS-20), symptoms using the Positive and Negative Syndrome Scale (PANSS), and neurocognition using the MATRICS battery among 65 adults with schizophrenia spectrum disorders in a non-acute phase of illness. Partial correlations controlling for the effects of social desirability revealed that difficulty identifying feelings and externally oriented thinking were linked with greater levels of neurocognitive deficits, while difficulty describing feelings was related to heightened levels of emotional distress. To explore whether neurocognition and affective symptoms were uniquely related to alexithymia, a multiple regression was conducted in which neurocognitive scores and affective symptoms were allowed to enter to predict overall levels of alexithymia after controlling for social desirability. Results revealed both processing speed and anxiety uniquely contributed to the prediction of the total score on the TAS-20. Results suggest that dysfunctions in both cognitive and affective processes may be related to alexithymia in schizophrenia independently of one another.

Deficits in metacognitive capacity distinguish patients with schizophrenia from those with prolonged medical adversity

Research has suggested that many with schizophrenia experience decrements in synthetic metacognition, or the abilities to form integrated representations of oneself and others and then utilize that knowledge to respond to problems. Although such deficits have been linked with functional impairments even after controlling for symptoms and neurocognition, it is unclear to what extent these deficits can distinguish persons with schizophrenia from others experiencing significant life adversity but without psychosis. To explore this issue we conducted logistic regression analysis to determine whether assessment of metacognition could distinguish between 166 participants with schizophrenia and 51 adults with HIV after controlling for social cognition and education. Metacognition was assessed with the Metacognitive Assessment Scale Abbreviated (MAS-A), and social cognition with the Bell Lysaker Emotion Recognition Test. We observed that the MAS-A total score was able to correctly classify 93.4% of the schizophrenia group, with higher levels of metacognition resulting in increased likelihood of accurate categorization. Additional exploratory analyses showed specific domains of metacognition measured by the MAS-A were equally able to predict membership in the schizophrenia group. Results support the assertion that deficits in the abilities to synthesize thoughts about oneself and others into larger representations are a unique feature of schizophrenia.

Metacognitive functioning predicts positive and negative symptoms over 12 months in first episode psychosis

The negative symptoms of schizophrenia are a major source of impairment and distress but both pharmacological and psychological treatment options provide only modest benefit. Developing more effective psychological treatments for negative symptoms will require a more sophisticated understanding of the psychological processes that are implicated in their development and maintenance. We extended previous work by demonstrating that metacognitive functioning is related to negative symptom expression across the first 12 months of first episode psychosis (FEP). Previous studies in this area have either been cross-sectional or have used much older participants with long-standing symptoms. In this study, forty-five FEP participants were assessed three times over 12 months and provided data on PANSS rated symptoms, premorbid adjustment, metacognitive functioning, and DUP. Step-wise linear regression showed that adding metacognition scores to known predictors of negative symptoms (baseline symptom severity, gender, DUP, and premorbid academic and social adjustment) accounted for 62% of the variance in PANSS negative symptom scores at six months and 38% at 12 months. The same predictors also explained 47% of the variance in positive symptoms at both six and 12 months. However, exploration of the simple correlations between PANSS symptom scores and metacognition suggests a stronger univariate relationship between metacognition and negative symptoms. Overall, the results indicate that problems with mental state processing may be important determinants of negative symptom expression from the very early stages of psychosis. These results provide further evidence that metacognitive functioning is a potentially relevant target for psychological interventions.

The neuropsychology of self-reflection in psychiatric illness

The development of robust neuropsychological measures of social and affective function-which link critical dimensions of mental health to their underlying neural circuitry-could be a key step in achieving a more pathophysiologically-based approach to psychiatric medicine. In this article, we summarize research indicating that self-reflection (the inward attention to personal thoughts, memories, feelings, and actions) may be a useful model for developing such a paradigm, as there is evidence that self-reflection is (1) measurable with self-report scales and performance-based tests, (2) linked to the activity of a specific neural circuit, and (3) dimensionally related to mental health and various forms of psychopathology.

Assessing metacognition during a cognitive task: impact of "on-line" metacognitive questions on neuropsychological performances in a non-clinical sample

Whereas metacognition is of great interest for neuropsychological practice, little is known about the impact of metacognitive questions during a neuropsychological assessment. This study explored the impact of measuring "on-line" metacognitive processes on neuropsychological performances in a non-clinical population. Participants were randomly assigned to a "standard" or a "metacognitive" neuropsychological test procedure. The "standard" procedure assessed executive functions (Modified Card Sorting Test), episodic memory ("Rappel libre Rappel indicé" 16), working memory (digit span test Wechsler Adult Intelligence Scale III) and social cognition (Faces Test). In the "metacognitive" procedure, two questions were added after each item of these tests to evaluate "on-line" metacognitive monitoring and control. Working memory performances were better and episodic memory performances lower in the "metacognitive" versus the "standard" procedure. No significant difference was found concerning executive functioning or social cognition. The assessment of "on-line" metacognition might improve working memory performances by enhancing concentration, and might impair episodic memory performances by acting as a distractor. These findings may have implications for the development of cognitive remediation programs.

Metacognitive capacities for reflection in schizophrenia: implications for developing treatments

Models of schizophrenia, which focus exclusively on discrete symptoms and neurocognitive deficits, risk missing the possibility that a core feature of the disorder involves a reduced capacity to construct complex and integrated representations of self and others. This column details a new methodology that has been used to assess deficits in the metacognitive abilities that allow persons to form complex ideas about themselves and others and to use that knowledge to respond to psychosocial challenges in schizophrenia. Evidence is summarized supporting the reliability and validity of this method, as well as links this work has revealed between metacognition and psychosocial outcomes. It is suggested that this work points to the need to develop interventions which move beyond addressing symptoms and specific skills, and assist persons to recapture lost or atrophied metacognitive capacity and so form the kind of ideas about themselves and others needed, to move meaningfully toward recovery.
