Cognitive insight predicts favorable outcome in cognitive behavioral therapy for psychosis

The influence of gender in cognitive insight and cognitive bias in people with first-episode psychosis: an uncontrolled exploratory analysis

PURPOSE

Previous studies have investigated the role of gender in clinical symptoms, social functioning, and neuropsychological performance in people with first-episode psychosis (FEP). However, the evidence of gender differences for metacognition in subjects with FEP is still limited and controversial. The aim of the present study was to explore gender differences in cognitive insight and cognitive biases in this population.

METHODS

Cross-sectional study was carried out in a sample of 104 patients with FEP (35 females and 69 males) recruited from mental health services. Symptoms were assessed with the Positive and Negative Syndrome Scale, cognitive insight with the Beck Cognitive Insight Scale, and cognitive bias by the Cognitive Biases Questionnaire for Psychosis. The assessment also included clinical and sociodemographic characteristics.

RESULTS

After controlling for potential confounders (level of education, marital status, and duration of psychotic illness) analysis of covariance revealed that males presented greater self-reflectiveness (p = 0.004) when compared to females. However, no significant differences were found in self-certainty and composite index of the cognitive insight scale, as in the cognitive biases assessed.

CONCLUSIONS

Gender was an independent influence factor for self-reflectiveness, being better for males. Self-reflectiveness, if shown to be relatively lacking in women, could contribute to the design of more gender-sensitive and effective psychotherapeutic treatments, as being able to self-reflect predicts to better treatment response in psychosis.

Self-stigma and cognitive insight in individuals at ultra-high risk for psychosis

Background

Impaired cognitive insight and increased self-stigma have been consistently reported in individuals diagnosed with schizophrenia spectrum disorders, but little is known about its presence in individuals at ultra-high risk of developing a psychosis, although self-stigma is associated with transition.to psychosis. The current study examined whether self-stigma is already present in individuals at ultra-high risk of psychosis, and whether this is associated with impaired cognitive insight.

Methods

184 participants were recruited divided over three groups, namely individuals diagnosed with a schizophrenia spectrum disorder (SSD; n = 92, 34% females), individuals at ultra-high risk for psychosis (UHR; n = 43, 59% females) and general population controls (GPC; n = 49, 27% females). All participants completed assessments on demographic information (gender, age, education), and cognitive insight. In addition, participants with SSD and individuals at UHR completed a questionnaire on self-stigma.

Results

The level of self-stigma did not differ between individuals at UHR and individuals diagnosed with SSD. Cognitive insight also did not differ significantly between the three groups, but the subscale self-reflection differed between the three groups [F(2,184) = 4.20, p = 0.02], with the UHR and SSD groups showing more self-reflection. Pearson's correlation analyses showed that in individuals at UHR total cognitive insight and its self-reflection subscale were significantly associated with the alienation subscale of self-stigma, and in individuals with SSD self-certainty subscale of cognitive insight was significantly associated with stereotype endorsement.

Conclusion

Findings show that self-stigma was already present in the UHR phase, to a similar degree as in individuals with a diagnosis of a SSD, and is thus not dependent of previous experience of having a label of SSD. Cognitive insight in individuals at UHR of psychosis appears to be intact, but individuals at UHR showed more self-reflectiveness, and individuals at risk with high cognitive insight also experience high levels of self-stigma. Overall findings from our study suggest that pre-emptive interventions targeting self-stigma, while considering cognitive insight, are needed early on in manifestation of psychotic illness, preferably already in the UHR phase.

Insight in nonpsychotic disorders: A new model of insight and a systematic review of measures

OBJECTIVE

There is substantial research examining insight in psychotic disorders and in some nonpsychotic disorders. However, there has been little attention given to many nonpsychotic disorders. Research on insight in psychosis distinguishes between cognitive and clinical insight. In most studies examining insight in nonpsychotic disorders, definitions and assessments of insight vary significantly. The purpose of this review is to suggest a definition of insight in nonpsychotic disorders such that it can be used across different disorders.

METHOD

We systematically review the extant literature of insight in nonpsychotic disorders and analyze the assessments used in order to determine how well they capture these two types of insight. Then, we discuss how these two constructs can provide better understanding of the phenomenology of insight in nonpsychotic disorders.

RESULTS

The systematic search resulted in 99 articles. These articles used 17 different methods of measuring insight, containing 127 questions. Results of the content analysis of items suggested that measures of insight used in nonpsychotic disorders do not distinguish between cognitive and clinical insight, but that most questions (90%) can indeed be reliably differentiated.

CONCLUSION

We provide a multidimensional model of cognitive and clinical insight in nonpsychotic disorders, emphasizing the complexity of assessment and the importance of accurately defining insight. Such definitions have important theoretical and clinical implications, offering a better understanding of the concept of insight in nonpsychotic disorders.

Engagement with online psychosocial interventions for psychosis: A review and synthesis of relevant factors

BACKGROUND

Little is known about factors associated with engagement with online interventions for psychosis. This review aimed to synthesise existing data from relevant literature to develop a working model of potential variables that may impact on engagement with online interventions for psychosis.

METHODS

Online databases were searched for studies relevant to predictors of engagement with online interventions for psychosis; predictors of Internet use amongst individuals with psychosis; and predictors of engagement with traditional psychosocial treatments for psychosis. Data were synthesised into a conceptual model highlighting factors relevant to engagement with online interventions for psychosis.

RESULTS

Sixty-one studies were identified. Factors relevant to engagement related directly to the impact of psychosis, response to psychosis, integration of technology into daily lives and intervention aspects.

CONCLUSION

While several candidate predictors were identified, there is minimal research specifically investigated predictors of engagement with online interventions for psychosis. Further investigation examining both individual- and intervention-related factors is required to inform effective design and dissemination of online interventions for psychosis.

The emergence of digital mental health in low-income and middle-income countries: A review of recent advances and implications for the treatment and prevention of mental disorders

In low-income and middle-income countries (LMICs), emerging digital mental health interventions should be accompanied by regular and comprehensive assessment of available scientific evidence. This review aims to support efforts to monitor progress in digital mental health research, ensuring new evidence can guide researchers, clinicians, policymakers and program managers positioned to adopt and implement these digitally-enabled treatments. In accordance with PRISMA guidelines, an electronic database search from 2016 to 2020 yielded 37 digital intervention studies for detection, diagnosis, prevention, treatment, and/or management of a broad range of mental disorders in 13 LMICs. This date range was selected to update previous reviews. Most studies involved online interventions and many reported feasibility and acceptability, reflected by participant satisfaction or program adherence. About half the studies (N = 23) reported clinical benefits based on changes in mental health. For depression and mood disorders, some digital interventions showed improvements in depressive symptoms, quality of life, treatment adherence, and recovery. However, sample sizes were small and studies focused primarily on adults. Further limiting generalizability was the lack of consistency in clinical assessment and measurement tools between studies. No studies reported worsening symptoms, negative acceptability or dissatisfaction with digital interventions, suggesting possible publication bias. While digital interventions show promise, it remains difficult to conclude that digital interventions are effective from these studies, as it is prudent to exercise caution before drawing conclusions about clinical effectiveness. This review reflects continued growth in digital mental health research in LMICs and further highlights the need for rigorous evaluation of effectiveness and cost-effectiveness.

Does the Beck Cognitive Insight Scale predict change in delusional beliefs?

OBJECTIVES

The Beck Cognitive Insight Scale (BCIS) is composed of two subscales, self-reflectiveness and self-certainty, assessing reflectiveness and openness to feedback, and mental flexibility. Delusions have previously been associated with low cognitive insight. The aim of this study was to determine whether changes in BCIS scores predict changes in delusional beliefs.

METHODS

The study is a secondary analysis of a previously published randomized controlled trial. All participants had a psychotic disorder diagnosis and received treatment as usual, with half of them also receiving the cognitive restructuring intervention 'Michael's game'. Participants were assessed at three different times: at baseline (T1), at 3 months (T2), and at 9 months (T3). Cognitive insight was measured with the BCIS, belief flexibility with the Maudsley assessment of delusions schedule (MADS), and psychotic symptoms with the Brief Psychiatric Rating Scale (BPRS).

RESULTS

A total of 172 participants took part in the trial. After using generalized estimating equation (GEE) modelling, we observed (1) significant main effects of BCIS self-certainty and Time and (2) significant Time × BCIS self-certainty and Time × treatment group interaction effects on belief flexibility. Improvements in self-certainty (i.e., decrease in scores) were associated with more changes in conviction over time, more accommodation, improved ability in ignoring or rejecting a hypothetical contradiction and increased use of verification of facts. Medication and BPRS total scores were controlled for in the GEE analyses at their baseline values.

CONCLUSIONS

Overall improvement in BCIS self-certainty scores over time predicted better treatment outcomes as assessed with MADS items.

PRACTITIONER POINTS

Treatments for patients with psychosis should focus on improving cognitive insight as this seems to improve overall treatment outcomes and recovery. The Beck Cognitive Insight Scale can be used to measure changes during treatment and can predict treatment outcomes.

UnReal? Investigating the Sense of Reality and Psychotic Symptoms with Virtual Reality

Distortions of reality, such as hallucinations, are common symptoms of many psychiatric conditions. Accordingly, sense of reality (SoR), the ability to discriminate between true and false perceptions, is a central criterion in the assessment of neurological and psychiatric health. Despite the critical role of the SoR in daily life, little is known about how this is formed in the mind. Here, we propose a novel theoretical and methodological framework to study the SoR and its relation to psychotic symptoms. In two experiments, we employed a specialized immersive virtual reality (VR) environment allowing for well-controlled manipulations of visual reality. We first tested the impact of manipulating visual reality on objective perceptual thresholds (just noticeable differences). In a second experiment, we tested how these manipulations affected subjective judgments of reality. The results revealed that the objective perceptual thresholds were robust and replicable, demonstrating that SoR is a stable psychometric property that can be measured experimentally. Furthermore, reality alterations reduced subjective reality judgments across all manipulated visual aspects. Finally, reduced sensitivity to changes in visual reality was related to self-reported prodromal psychotic symptoms. These results provide evidence for the relevance of SoR in the assessment of psychosis and other mental disorders in which reality is distorted.

Understanding sex differences in cognitive insight across first-and-multiple episode psychosis

OBJECTIVE

Cognitive insight represents the capacity to self-reflect and consider external feedback when re-evaluating faulty beliefs. It is associated with specific cognitive capacities such as verbal memory, of which there is substantial evidence for sex differences in psychotic disorders. Like more general cognitive capacities, cognitive insight might too be modulated by sex differences.

METHOD

One hundred and seventy-one first episode psychosis (FEP; 123 males, 48 females), and 203 multiple episode psychosis (MEP; 147 males, 56 females) participants completed the Beck Cognitive Insight Scale (BCIS). A two-way MANOVA was conducted on the three BCIS measures (self-reflectiveness, self-certainty, composite index) with sex (male, female) and illness stage (FEP, MEP) as factors, followed by two-way ANOVAs and a post hoc test of simple effects.

RESULTS

The only significant interaction to emerge was between sex and illness stage in self-certainty (F(1, 373) = 5.88, p = .016). A test of simple effects revealed that self-certainty group means were significantly different for males and females in FEP, where females had lower self-certainty than males (p = .053) but not during MEP (p = .119).

CONCLUSION

Sex differences do not modulate cognitive insight in MEP, which may be attributable to females having greater positive symptom severity than males. In FEP however, results revealed that females were significantly less self-certain than males. Lower self-certainty relative to self-reflectiveness predicts treatment response in psychological interventions, and as such future FEP studies should explore sex differences in psychological interventions.

Effects of Creative Thinking and Its Personality Determinants on Negative Emotion Regulation

This study investigated the relationship between creativity and negative emotion, and the effects of integrating creative insight into the reappraisal process on negative emotions. In Study 1, participants' creativity and baseline anxiety levels were measured; then anxiety was induced, and anxiety levels were reassessed. In Study 2, participants wrote about past negative events and then completed the positive and negative affect schedule. They were split into three groups (insight reappraisal, simple reappraisal, or control groups); each of them received a separate intervention, and then they completed positive and negative affect schedule again. In Study 3, participants were randomly assigned to insight reappraisal or control groups; apart from measuring cognitive changes, the procedures were identical to Study 2. All participants were undergraduate students. Results showed that flexibility, originality, risk-taking, and complexity are negatively correlated with anxiety, and that insight reappraisal can induce insight experience and enhance cognitive changes, and reduce negative emotional responses. Therefore, integrating creative insight into the reappraisal process can enhance its effectiveness in reducing negative emotions.

Brief coping strategy enhancement for distressing voices: Predictors of engagement and outcome in routine clinical practice

Cognitive behaviour therapy is recommended internationally as a treatment for psychosis (targeting symptoms such as auditory hallucinations, or "voices"). Yet mental health services are commonly unable to offer such resource-intensive psychological interventions. Brief, symptom-specific and less resource-intensive therapies are being developed as one initiative to increase access. However, as access increases, so might the risk of offering therapy to clients who are not optimally disposed to engage with and benefit from therapy. Thus, it is important to identify who is most/least likely to engage with and benefit from therapy, and when. In the current study, 225 clients were assessed for suitability for a brief, 4-session, manualized, cognitive behaviour therapy-based intervention for voices (named coping strategy enhancement therapy) and 144 commenced therapy, at a transdiagnostic voices clinic based in Sussex, UK. This article reports on the value of depression, anxiety, stress, insight into the origin of voices, length of voice hearing, and demographics in the prediction of engagement and outcomes. The study found that higher levels of baseline depression, anxiety, and stress were significantly associated with poorer outcomes, especially if clients also had high levels of voice-related distress. The engagement analyses showed that levels of voice-related distress at baseline predicted dropout. These findings highlight the importance of assessing negative affect and voice-related distress prior to commencing therapy for distressing voices, to help determine if the client is suitable or ready for brief-coping strategy enhancement.

Cognitive insight and objective quality of life in people with schizophrenia and auditory hallucinations

Poor cognitive insight in schizophrenia has been linked to delusions, hallucinations, and negative symptoms as well as to depressive/anxiety symptoms. Its impact on quality of life has been less studied, especially in schizophrenia subjects with ongoing auditory hallucinations. The Beck Cognitive Insight Scale (BCIS) and the Quality of Life Scale (QLS) were administered to subjects who met DSM IV criteria for schizophrenia after due translation and validation. All subjects reported ongoing auditory hallucinations at recruitment. Mean composite cognitive insight scores from participants (N = 60) (2.97 ± 2.649) were in the lower range as compared to published literature. Cognitive insight scores as well as self-reflectiveness subscale scores, but not self-certainty scores, correlated significantly with the QLS scores p < 0.001. Results suggest that better cognitive insight, especially self-reflectiveness, may be linked to better quality of life. Self-reflectiveness could be a useful construct to address in psychotherapy to improve rehabilitation.

A systematic review examining factors predicting favourable outcome in cognitive behavioural interventions for psychosis

Psychosis is a debilitating mental health condition affecting approximately 4 persons per 1000. Cognitive behavioural therapy for psychosis (CBTp) has been shown to be an effective treatment for psychosis and is recommended by several national guidelines. CBTp does not work equally well with everyone, however, with some 50% of clients receiving little benefit. This review sets out to systematically assess the literature and methodological quality of a number of studies, which examine factors predicting successful outcome in CBTp. The databases CINAHL, Cochrane, EBSCO, EMBASE, ISI Web of Science, MEDLINE (Ovid), PsycARTICLES, PsycINFO, PubMed, and Scopus were electronically searched. English language articles in peer reviewed journals were reviewed. Search terms "psychosis", "psychotic disorder", "cognitive behavioural therapy", "cognitive therapy", "randomised controlled trial", "predictor", and "treatment outcome" in various combinations were used as needed. Only randomised controlled trials (RCTs) were included. Results suggest that female gender, older age, and higher clinical insight at baseline, each predicted better outcome in CBT interventions with psychotic patients, as did a shorter duration of the illness, and higher educational attainment. Several other factors, such as higher symptom severity at baseline, were suggestive of predictive capacity but further research to clarify was indicated. Providers of mental healthcare should consider these findings when offering CBTp. The onus is also on healthcare providers to better equip non-responders to CBTp. Further investigation into a limited number of predictive factors, with an agreed set of outcome measures, would allow future researchers more direct comparisons between studies.

Can cognitive insight predict symptom remission in a first episode psychosis cohort?

BACKGROUND

The outcome of first episode psychosis (FEP) is highly variable and difficult to predict. Cognitive insight measured at illness onset has previously been found to predict psychopathology 12-months later. The aims of this study were to examine whether the prospective relationship between cognitive insight and symptom severity is evident at four-years following FEP and to examine some psychological correlates of cognitive insight.

METHODS

FEP participants (n = 90) completed the Beck Cognitive Insight Scale (BCIS) at illness onset, and associations between BCIS scores with symptom severity outcomes (4-years after FEP) were assessed. The BCIS scales (self-reflectiveness and self-certainty) were examined as a composite score, and individually compared to other cognitive measures (IQ and jumping to conclusions (JTC) bias).

RESULTS

Regression analyses revealed that the cognitive insight composite did not predict 4-year symptom remission in this study while the self-reflection subscale of the BCIS predicted severity of symptoms at 4-years. Self-certainty items of the BCIS were not associated with symptom severity. Significant correlations between the JTC bias, self-certainty and IQ were found, but self-reflection did not correlate with these other cognitive measures.

CONCLUSIONS

Self-reflective capacity is a more relevant and independent cognitive construct than self-certainty for predicting prospective symptom severity in psychosis. Improving self-reflection may be a useful target for early intervention research.

Brain connectivity changes occurring following cognitive behavioural therapy for psychosis predict long-term recovery

Little is known about the psychobiological mechanisms of cognitive behavioural therapy for psychosis (CBTp) and which specific processes are key in predicting favourable long-term outcomes. Following theoretical models of psychosis, this proof-of-concept study investigated whether the long-term recovery path of CBTp completers can be predicted by the neural changes in threat-based social affective processing that occur during CBTp. We followed up 22 participants who had undergone a social affective processing task during functional magnetic resonance imaging along with self-report and clinician-administered symptom measures, before and after receiving CBTp. Monthly ratings of psychotic and affective symptoms were obtained retrospectively across 8 years since receiving CBTp, plus self-reported recovery at final follow-up. We investigated whether these long-term outcomes were predicted by CBTp-led changes in functional connections with dorsal prefrontal cortical and amygdala during the processing of threatening and prosocial facial affect. Although long-term psychotic symptoms were predicted by changes in prefrontal connections during prosocial facial affective processing, long-term affective symptoms were predicted by threat-related amygdalo-inferior parietal lobule connectivity. Greater increases in dorsolateral prefrontal cortex connectivity with amygdala following CBTp also predicted higher subjective ratings of recovery at long-term follow-up. These findings show that reorganisation occurring at the neural level following psychological therapy can predict the subsequent recovery path of people with psychosis across 8 years. This novel methodology shows promise for further studies with larger sample size, which are needed to better examine the sensitivity of psychobiological processes, in comparison to existing clinical measures, in predicting long-term outcomes.

Cognitive Behavioral Therapy Normalizes Functional Connectivity for Social Threat in Psychosis

Psychosis is often characterized by paranoia and poor social functioning. Neurally, there is evidence of functional dysconnectivity including abnormalities when processing facial affect. We sought to establish whether these abnormalities are resolved by cognitive behavioral therapy for psychosis (CBTp). The study involved 38 outpatients with one or more persistent positive psychotic symptoms, and 20 healthy participants. All participants completed an implicit facial affect processing task during functional magnetic resonance imaging (fMRI). Subsequently, patients either continued to receive standard care only (SCO,n= 16) or received CBTp on top of standard care (+CBTp,n= 22), with fMRI repeated 6-8 months later. To examine the mechanisms underlying CBTp-led changes in threat processing and appraisal, functional connectivity during the social threat (angry faces) condition was assessed separately from left amygdala and right dorsolateral prefrontal cortex (DLPFC) seeds. At baseline, patients, compared with healthy participants, showed greater amygdala connectivity with the insula and visual areas, but less connectivity with somatosensory areas. These differences normalized following CBTp and, compared with the SCO group, the +CBTp group showed greater increases in amygdala connectivity with DLPFC and inferior parietal lobule, with the latter correlating with improvement in positive symptoms. From the DLPFC seed, the +CBTp (compared with SCO) group showed significantly greater increase in DLPFC connectivity with other prefrontal regions including dorsal anterior cingulate and ventromedial prefrontal cortex. These findings indicate that CBTp strengthens connectivity between higher-order cognitive systems and those involved in threat and salience, potentially facilitating reappraisal.

Cognitive insight is associated with cortical thickness in first-episode psychosis

Compared to non-clinical subjects, people with psychosis show poor cognitive insight as reflected in low Self-Reflectiveness and high Self-Certainty. Neuroimaging studies have reported that 1) low Self-Reflectiveness is associated with volumetric reductions in ventrolateral prefrontal cortex (VLPFC), 2) higher Self-Certainty is associated with volumetric reductions in hippocampus, and 3) higher Self-Certainty is associated with fractional anisotropy in the fornix, in people with psychosis. The aims of the current study were to expand on this research by 1) performing an exploratory whole-brain cortical thickness analysis of the neural correlates of cognitive insight, to reveal whether regions outside the VLPFC are important for cognitive insight, and 2) to evaluate associations between cognitive insight and subfields of the hippocampus, which are distinct, interacting, and have different functions. We also aimed to replicate previous research documenting associations between cognitive insight and 3) total hippocampal volumes and 4) fornix fractional anisotropy. Fifteen people with a first-episode psychosis completed the Beck Cognitive Insight Scale and provided magnetic resonance and diffusion tensor imaging scans. Cortical thickness and hippocampal volumes were analyzed in FreeSurfer, and fornixfractional anisotropy was analyzed in Diffusion Toolkit/TrackVis. Higher Self-Reflectiveness and lower Self-Certainty significantly associated with thickness and thinness in VLPFC, respectively, as well as thickness and thinness in widespread frontal, parietal and temporal cortices. No associations emerged between Self-Reflectiveness or Self-Certainty and hippocampal total or sub-field volumes, or fornix fractional anisotropy. Results suggest that the neural correlates of cognitive insight involve a network of frontal, temporal and parietal brain regions.

Does the Beck Cognitive Insight Scale Predict Response to Cognitive Remediation in Schizophrenia?

Cognitive remediation therapy (CRT) has emerged as a viable treatment option for people diagnosed with schizophrenia presenting disabling cognitive deficits. However, it is important to determine which variables can influence response to CRT in order to provide cost-effective treatment. This study's aim was to explore cognitive insight as a potential predictor of cognitive improvement after CRT. Twenty patients with schizophrenia completed a 24-session CRT program involving 18 hours of computer exercises and 6 hours of group discussion to encourage generalization of cognitive training to everyday activities. Pre- and posttest assessments included the CogState Research Battery and the Beck Cognitive Insight Scale (BCIS). Lower self-certainty on the BCIS at baseline was associated with greater improvement in speed of processing (r s = -0.48; p < 0.05) and visual memory (r s = -0.46; p < 0.05). The results of this study point out potential associations between self-certainty and cognitive improvement after CRT, a variable that can easily be measured in clinical settings to help evaluate which patients may benefit most from the intervention. They also underline the need to keep investigating the predictors of good CRT outcomes, which can vary widely between patients.

The relationship between cognitive insight and quality of life in schizophrenia spectrum disorders: Symptom severity as potential moderator

Cognitive insight is implicated in the formation and maintenance of hallucinations and delusions. However, it is not yet known whether cognitive insight relates to broader outcome measures like quality of life. In the current study, we investigated whether the component elements of cognitive insight-self-certainty and self-reflectiveness-were related to quality of life for 43 outpatients with schizophrenia or schizoaffective disorder. Cognitive insight was assessed using the Beck Cognitive Insight Scale (BCIS) while quality of life was assessed with Quality of Life Scale (QLS). We tested whether this relationship was moderated by clinical insight and symptom severity using the Scale to Assess Unawareness of Mental Disorder (SUMD) and the Positive and Negative Syndrome Scale (PANSS). We found that self- reflectiveness had an unmoderated positive relationship with quality of life. Self-certainty was associated with better quality of life for people with more severe symptoms. Theoretical and clinical implications of these findings are discussed and areas of future research are proposed.

Orbitofrontal cortex, emotional decision-making and response to cognitive behavioural therapy for psychosis

Grey matter volume (GMV) in the orbitofrontal cortex (OFC) may relate to better response to cognitive behavioural therapy for psychosis (CBTp) because of the region׳s role in emotional decision-making and cognitive flexibility. This study aimed to determine the relation between pre-therapy OFC GMV or asymmetry, emotional decision-making and CBTp responsiveness. Emotional decision-making was measured by the Iowa Gambling task (IGT). Thirty patients received CBTp+standard care (CBTp+SC; 25 completers) for 6-8 months. All patients (before receiving CBTp) and 25 healthy participants underwent structural magnetic resonance imaging. Patients׳ symptoms were assessed before and after therapy. Pre-therapy OFC GMV was measured using a region-of-interest approach, and IGT performance was measured as overall learning, attention to reward, memory for past outcomes and choice consistency. Both these measures, were comparable between patient and healthy groups. In the CBTp+SC group, greater OFC GMV correlated with positive symptom improvement, specifically hallucinations and persecution. Greater rightward OFC asymmetry correlated with improvement in several negative and general psychopathology symptoms. Greater left OFC GMV was associated with lower IGT attention to reward. The findings suggest that greater OFC volume and rightward asymmetry, which maintain the OFC׳s function in emotional decision-making and cognitive flexibility, are beneficial for CBTp responsiveness.

Relationship between cognitive insight and attenuated delusional symptoms in individuals with at-risk mental state

Cognitive insight, defined as the ability to evaluate and correct one׳s own distorted beliefs and misinterpretations, is hypothesized to contribute to the development of psychotic symptoms. We investigated cognitive insight in individuals with at-risk mental state (ARMS), which is associated with a clinically high risk of psychosis. Sixty individuals with ARMS were compared with 200 healthy controls in terms of cognitive insight measured using the Beck Cognitive Insight Scale. We also investigated the relationship between cognitive insight and attenuated delusional symptoms. In addition, we examined differences in the cognitive insight of individuals with ARMS with or without near-threshold delusional symptoms and differences in the cognitive insight of individuals with ARMS with or without later transition to psychosis. The results showed that individuals with ARMS exhibited higher self-certainty than healthy controls, indicating impairments in cognitive insight in the former. More importantly, our results revealed that self-certainty was correlated with attenuated delusional symptoms and that individuals with ARMS who had near threshold delusional symptoms had higher self-certainty. These findings indicate that overconfidence in one׳s own beliefs or judgments might be related to the formation and maintenance of attenuated delusions in individuals with ARMS.

Who stays, who benefits? Predicting dropout and change in cognitive behaviour therapy for psychosis

This study investigates the predictors of outcome in a secondary analysis of dropout and completer data from a randomized controlled effectiveness trial comparing CBTp to a wait-list group (Lincoln et al., 2012). Eighty patients with DSM-IV psychotic disorders seeking outpatient treatment were included. Predictors were assessed at baseline. Symptom outcome was assessed at post-treatment and at 1-year follow-up. The predictor×group interactions indicate that a longer duration of disorder predicted less improvement in negative symptoms in the CBTp but not in the wait-list group whereas jumping-to-conclusions was associated with poorer outcome only in the wait-list group. There were no CBTp specific predictors of improvement in positive symptoms. However, in the combined sample (immediate CBTp+the delayed CBTp group) baseline variables predicted significant amounts of positive and negative symptom variance at post-therapy and 1-year follow-up after controlling for pre-treatment symptoms. Lack of insight and low social functioning were the main predictors of drop-out, contributing to a prediction accuracy of 87%. The findings indicate that higher baseline symptom severity, poorer functioning, neurocognitive deficits, reasoning biases and comorbidity pose no barrier to improvement during CBTp. However, in line with previous predictor-research, the findings imply that patients need to receive treatment earlier.

Differential associations of cognitive insight components with pretreatment characteristics in first-episode psychosis

An increasing number of studies have focused on cognitive insight (i.e. awareness of one's own thinking) in psychotic disorders. However, little is known about the premorbid and pretreatment correlates of cognitive insight in the early course of psychosis. One hundred and three patients experiencing first-episode psychosis (FEP) were assessed shortly after treatment initiation for cognitive insight. Pretreatment and baseline clinical, functional and neurocognitive characteristics were examined. The self-reflectiveness dimension of cognitive insight was independently associated with clinical insight and executive functioning, whereas self-certainty was associated with premorbid IQ, premorbid academic adjustment and clinical insight. The amount of variance explained by the independent variables was small to moderate. Self-reflectiveness and self-certainty have differential pretreatment correlates in FEP and may reflect separate cognitive processes which require targeted interventions.

The nature and evolution of insight in schizophrenia: a multi-informant longitudinal study of first-episode versus chronic patients

BACKGROUND AND AIMS

This study investigated a novel distinction between two possible sources of poor insight in schizophrenia: primary unawareness, in which the ill person is not aware that other people think one has a problem, and secondary unawareness (or disagreement), in which a person does appreciate that other people think one has a problem. A secondary goal was to compare the evolution of insight in first-episode and chronic schizophrenia.

METHODS

Sixty-eight first-episode and 51 chronic patients were administered two versions of the Scale of Unawareness of Mental Disorder (SUMD) at three time points: hospital admission, discharge, and 6-month post-discharge. In the first standard SUMD version, they were asked about their own opinions, whereas in the second modified version, they were asked about their best guess of their doctor's opinion.

RESULTS

While overall level of unawareness remained stable within each single episode, there were significant Type of Unawareness (primary versus secondary) by Clinical Status (admission versus discharge versus 6-month post-discharge) and Type of Unawareness by Phase of Illness (first-episode versus chronic) interaction effects. More specifically, in the first-episode group, primary unawareness steadily decreased over time. In contrast, in the chronic group, primary unawareness decreased markedly during hospitalization and returned to baseline after discharge.

CONCLUSIONS

These results provide preliminary support for the notion that impaired insight is an additive outcome of primary unawareness and disagreement, and that change in insight over time occurs mostly at the level of their relative proportion as opposed to their overall sum. Implications for studying and treating poor insight in schizophrenia are discussed.

Neuropsychological, clinical and cognitive insight predictors of outcome in a first episode psychosis study

The outcome of first episode psychosis (FEP) is highly variable and difficult to predict. We studied prospectively the impact of poor insight and neuropsychological deficits on outcomes in a longitudinal cohort of 127 FEP patients. Participants were assessed on 5 domains of cognitive function and 2 domains of insight (clinical and cognitive). At 12 months, patients were assessed again for symptom severity and psychosocial function. Regression analyses revealed that cognitive insight (a measure of self-reflectiveness and self-certainty) was the best baseline predictor of overall psychopathology at 12 months whereas executive function performance at admission to the study indicated later severity of negative symptoms. Other neuropsychological and insight measures were poor predictors of psychosocial function at 1 year. The results suggest that specific neuropsychological and insight factors have separate predictive capacities indicating that they are distinct psychological processes in psychosis. Cognitive insight proved to be a useful prognostic indicator, and should be considered for future studies and as a potential focus for treatment.

Insight in stable schizophrenia: relations with psychopathology and cognition

OBJECTIVE

This study evaluated the relationship among insight, sociodemographic and clinical variables, symptoms and cognitive functions in a population of outpatients with stable schizophrenia, in order to identify possible contributing factors to awareness.

METHOD

Two-hundred and seventy-six consecutive outpatients with stable schizophrenia were enrolled in a cross-sectional study. All subjects were assessed by psychiatric scales and interview, and a wide neuropsychological battery. A factor analysis was performed to identify cognitive factors and multiple regression analyses were executed to test the contribution of variables considered to insight.

RESULTS

Our results showed that positive and negative symptoms, executive functions, verbal memory-learning were contributors of awareness of mental illness; positive and negative symptoms explained variability in awareness of the need for treatment; positive symptoms and executive functions contributed to awareness of the social consequences of disorder.

CONCLUSIONS

These results suggested that insight was partially influenced by positive and negative symptoms and by cognitive functions. A complex system of overlapping variables may underlie impaired insight, contributing to a different extent to specific dimensions of poor insight in patients with stable schizophrenia.

Cognitive Behavioral Therapy and Work Outcomes: Correlates of Treatment Engagement and Full and Partial Success in Schizophrenia

Background: Cognitive behavior therapy (CBT) has been found to be generally effective for persons with schizophrenia. Less is known however about those who will engage in this treatment, and among those who engage, who benefits more versus less from this intervention. Aims: This study sought to identify factors associated with treatment engagement and response in persons with psychosis engaged in CBT focused on enhancing work function. Method: Participants were 50 adults with schizophrenia-spectrum disorders participating in a randomized control trial that offered both CBT and a protected employment position over 26 weeks. Survival analysis and discriminant analyses were used to analyze the data. Results: Results indicated that poor treatment engagement and engagement in work was associated with lower educational attainment, more severe baseline levels of negative symptoms, and lower baseline scores on the Arithmetic and Digit Symbol subscales of the WAIS-III. Amongst those participants who did engage, younger age and poorer working memory as assessed by the Arithmetic subscale predicted shorter initial job tenure. More severe levels of positive symptoms and lower self-esteem during the later stages of treatment were associated with worse employment outcomes across the study period. Conclusions: These findings evidence differential predictors of engagement and success and suggest that a subgroup of persons with schizophrenia engaged in CBT and a vocational placement are at risk for poor functional outcomes associated with psychological factors that evolve over time.

Association between insight, cognitive insight, positive symptoms and violence in patients with schizophrenia

BACKGROUND

Violence is a significant clinical and public concern and is a frequent occurrence in patients with schizophrenia. The relationship between insight and violence remains controversial. In addition, there is a lack of research on insight, cognitive insight, demographic and psychopathologic variables in violent versus nonviolent schizophrenia patients.

AIM

We aimed to compare insight, cognitive insight, psychopathological and demographic variables in violent and nonviolent subjects suffering from schizophrenia. In addition, we aimed to determine the demographic and clinical predictors of violent behaviour in patients with schizophrenia.

METHOD

We recruited 133 schizophrenic patients without concomitant substance abuse or axis II disorder. Diagnoses were based on the SCID-I and SCID-II. Violent behaviours were assessed using the Overt Aggression Scale. Insight and cognitive insight were assessed with the Scale to Assess Unawareness of Mental Disorder and the Beck Cognitive Insight Scale, respectively.

RESULTS

We compared 47 patients with violent schizophrenia with 86 nonviolent patients. Non-violent patients had more severe depression, lower scores on positive symptoms, better clinical insight, more self-reflectivity and higher R-C index scores than did violent patients. In addition, history of violence, lower self-reflectiveness, worse clinical insight and delusion severity were significant predictors of violence in schizophrenia.

CONCLUSION

The present study suggests that the inclusion of insight and cognitive insight may increase the prediction of violence in this population. In addition, clinicians should consider using non-pharmacological techniques that are based on cognitive behaviour therapy and enhance insight, particularly cognitive insight, among patients with schizophrenia who exhibit violent behaviour.

Socially naïve self-appraisal moderates the relationship between cognitive insight and positive symptoms in schizophrenia

Cognitive insight refers to awareness of one's own thinking. Research has found deficits in cognitive insight in schizophrenia but studies of its links with positive symptoms and delusions have been equivocal. One possibility is that the association of cognitive insight with positive symptoms and delusions is moderated by other factors. To explore this issue this study examined whether level of socially naive self-appraisal moderated the relationship of two forms of cognitive insight, self-reflectivity and self-certainty with delusions and positive symptoms. Participants were 92 adults, with diagnoses of schizophrenia or schizoaffective disorder, who were administered the Positive and Negative Syndrome Scale, self-deceptive subscale from the Marlowe-Crowne Social Desirability Scale and the Beck Cognitive Insight Scale. Stepwise multiple regressions with the interaction term of the predictive and moderator variables suggested that social naiveté moderates the relationship between self-reflectivity and self-certainty with positive symptoms in general. Moreover, association between self-certainty and delusions was also moderated by social naiveté self-appraisal. All models were significant after controlling for willful impression management as well as a measure of executive function. Results suggest that higher levels of self-certainty are a risk factor for having greater positive symptoms including more severe levels of delusions, when one has a view of oneself that is not tempered by the perceptions of others. Concerning lower levels of self-reflectivity it may be that this combined with a socially naïve view of oneself leaves persons less inhibited when they are tempted to accept unusual thoughts and perceptions as accurate. Implications for treatment are discussed.

Cognitive insight in schizophrenia: the missing link between insight and neurocognitive complaint?

The aim of this study was to explore the associations between cognitive insight, clinical insight, and neurocognitive complaint in a sample of 54 outpatients with schizophrenia spectrum disorders. Cognitive insight assessed using the Beck Cognitive Insight Scale (BCIS) was not associated with clinical insight assessed using the Scale to Assess Unawareness of Mental Disorder. Associations were found between the BCIS scores and the neurocognitive complaints assessed using the Subjective Scale to Investigate Cognition in Schizophrenia. A high level of neurocognitive complaints was positively associated with self-reflectiveness and negatively associated with self-certainty about beliefs and judgments. These results provide further support for the construct validity of the BCIS. The data also suggest that cognitive insight and neurocognitive complaint are close constructs that should be differentiated from awareness of having a mental illness.

Assessment of cognitive insight: a qualitative review

The concept of cognitive insight was introduced in 2004 to describe the capacity of patients with psychosis to distance themselves from their psychotic experiences, reflect on them, and respond to corrective feedback. The Beck Cognitive Insight Scale (BCIS) was developed to evaluate these aspects of cognitive flexibility and to complement scales that describe the lack of awareness of mental illness and its characteristics. The BCIS has generated a moderate research literature, which is the subject of the current review. Several independent groups have demonstrated that the BCIS is reliable, demonstrates convergent and construct validity, and distinguishes patients with psychosis from healthy controls and patients without psychosis. While the majority of the studies have focused on the relationship of the BCIS to delusions, several have examined its relationship to negative symptoms, depression, anxiety, and functional outcome. Cognitive insight has predicted positive gains in psychotherapy of psychosis, and improvement in cognitive insight has been correlated with improvement in delusional beliefs. Finally, preliminary findings relate neurocognition, metacognition, and social cognition, as well as reduced hippocampal volume to cognitive insight. A heuristic framework is presented to guide future research.

Sensorimotor gating and clinical outcome following cognitive behaviour therapy for psychosis

BACKGROUND

Prepulse inhibition (PPI) of the startle response refers to the ability of a weak prestimulus to transiently inhibit the response to a closely following strong sensory stimulus. PPI provides an operational index of sensorimotor gating and is reduced, on average, in people with schizophrenia, relative to healthy people. Given the variable response to Cognitive Behaviour Therapy for psychosis (CBTp) and positive associations between pre-therapy brain and cognitive functions and CBT outcome across disorders, we examined whether pre-therapy level of PPI is associated with clinical outcome following CBTp.

METHOD

Fifty-six outpatients stable on medication with at least one distressing symptom of schizophrenia and willing to receive CBTp in addition to their usual treatment were assessed on acoustic PPI. Subsequently, 28 patients received CBTp (CBTp+treatment-as-usual, 23 completers) for 6-8months and 28 continued with their treatment-as-usual (TAU-alone, 17 completers). Symptoms were assessed (blindly) at entry and follow-up.

RESULTS

The CBTp+TAU and TAU-alone groups did not differ demographically, clinically or in PPI at baseline. The CBTp+TAU group showed improved symptoms relative to the TAU-alone group, which showed no change, at follow-up. Pre-therapy PPI level correlated positively with post-CBTp symptom improvement.

CONCLUSIONS

Relatively intact sensorimotor gating is associated with a good clinical response following a 6-8months course of NICE compliant CBTp in schizophrenia. Pharmacological or psychological interventions capable of improving PPI may enhance the effectiveness of CBTp in people with schizophrenia, particularly in those who fail to show clinical improvement with currently available antipsychotic drugs and adjunctive CBTp.

Cognitive insight and its relationship with symptoms in deficit and nondeficit schizophrenia

Patients with deficit schizophrenia have worse cognition and poorer social functioning compared with those with nondeficit schizophrenia. Insight is another domain in which these two groups might differ. However, there is no literature data specifically on cognitive insight impairment in deficit versus nondeficit schizophrenia. We compared 40 patients with deficit schizophrenia with 81 nondeficit patients and found that schizophrenic patients with deficit syndrome were more self-reflective and have higher self-reflectiveness-self-certainty index scores than did those without deficit syndrome. These differences remained significant when analysis was controlled for sex, age, education, and depression severity. On the other hand, there was no significant difference in self-certainty scores between two groups. In addition, we found significant relationships between cognitive insight and specific psychotic symptoms. A better understanding of the cognitive component of insight in schizophrenia with deficit syndrome may help us to understand the true relationship between insight and negative symptoms and contribute to the development of more efficient cognitive strategies, thus improving patients' outcome in a severely disabled psychiatric patient group.

A preliminary exploration of predictors of outcome and cognitive mechanisms of change in cognitive behaviour therapy for psychosis in people not taking antipsychotic medication

BACKGROUND

Cognitive behaviour therapy (CBT) has been shown to be effective in an open trial for people with psychotic disorders who have not been taking antipsychotic medication. There is little known about predictors of outcome in CBT for psychosis and even less about hypothesised mechanisms of change.

METHOD

20 participants with schizophrenia spectrum disorders received CBT in an exploratory trial. Our primary outcome was psychiatric symptoms measured using the PANSS. Secondary outcomes were dimensions of hallucinations and delusions, self-rated recovery and social functioning, and hypothesised mechanisms of change included appraisals of psychotic experiences, dysfunctional attitudes and cognitive insight. We also measured patient characteristics that may be associated with outcome.

RESULTS

T-tests revealed that several of the hypothesised mechanisms did significantly change over the treatment and follow-up periods. Correlational analyses showed that reductions in negative appraisals of psychotic experiences were related to improvements on outcome measures and that shorter duration of psychosis and younger age were associated with greater changes in symptoms.

CONCLUSIONS

CBT based on a specific cognitive model appears to change the hypothesised cognitive mechanisms, and these changes are associated with good outcomes. CBT may be more effective for those who are younger with shorter histories of psychosis.

Clinical and Cognitive Insight in a Compensatory Cognitive Training Intervention

The impact of limited insight is a crucial consideration in the treatment of individuals with psychiatric illness. In the context of psychosis, both clinical and cognitive insight have been described. This study aimed to evaluate the relationships between clinical and cognitive insight and neuropsychological functioning, psychiatric symptom severity, and everyday functioning in patients with a primary psychotic disorder participating in a compensatory cognitive training (CT) intervention. Sixty-nine individuals diagnosed with a primary psychotic disorder were randomized to a 3-month CT intervention or to standard pharmacotherapy, and they completed a comprehensive neuropsychological, clinical, and functional battery at baseline, 3 months, and 6 months. The CT intervention focused on habit formation and compensatory strategy learning in four domains: prospective memory, attention and vigilance, learning and memory, and problem-solving/cognitive flexibility. At baseline, better clinical insight was significantly related to better executive functioning and less severe negative symptoms. There was no significant association between cognitive insight and cognitive functioning, symptom severity, or everyday functioning ability. The CT intervention did not have an effect on clinical or cognitive insight, but better cognitive insight prior to participation in CT significantly predicted decreased positive and depressive symptom severity posttreatment, and better clinical insight predicted improved self-reported quality of life. Although clinical insight is related to executive functioning, the correlates of cognitive insight remain elusive. Intact insight appears to be beneficial in ameliorating clinical symptomatology like positive symptoms and depression, rather than augmenting cognition. It may be valuable to develop brief interventions aimed at improving clinical and cognitive insight prior to other psychosocial rehabilitation in order to maximize the benefit of treatment.

Coping styles predict responsiveness to cognitive behaviour therapy in psychosis

The study aimed to determine the clinical and neuropsychological predictors of responsiveness to cognitive behavioural therapy for psychosis (CBTp). Sixty patients with schizophrenia or schizoaffective disorder and 25 healthy individuals took part in the study. Thirty patients (25 protocol completers) received CBTp in addition to standard care (SC); 30 patients (18 protocol completers) received SC only. All patients were assessed on symptoms using the Positive and Negative Syndrome Scale (PANSS) and clinical and neuropsychological function before and after CBTp. Symptoms and self-esteem improved to a greater extent in the CBTp+SC than SC control group. Greater pre-therapy coping ability and the self-reflectiveness dimension of cognitive insight at baseline predicted improvement in symptoms in the CBTp+SC group, but not the SC control group, explaining up to 21% of the variance in symptom improvement. Pre-therapy neuropsychological function, duration of illness, clinical insight and gender did not predict CBTp responsiveness. Being able to have a range of coping strategies and reflect on one's experiences while refraining from overconfidence in one's interpretations before therapy is conducive to better CBTp responsiveness.

Detecting and defusing cognitive traps: metacognitive intervention in schizophrenia

PURPOSE OF REVIEW

Until recently, psychological therapy for schizophrenia was considered harmful or inefficient by many clinicians. The reservation against psychotherapy is partly rooted in the assumption that delusions in particular and schizophrenia in general are not amenable to psychological understanding and represent 'utter madness'. However, meta-analyses suggest that cognitive intervention is effective in ameliorating schizophrenia symptoms. In addition, evidence has accumulated that cognitive biases, such as jumping to conclusions, are involved in the pathogenesis of schizophrenia positive symptoms, particularly delusions. A recently developed group program, called metacognitive training (MCT), is presented targeting these biases. MCT is a hybrid of psychoeducation, cognitive remediation and cognitive-behavioural therapy.

RECENT FINDINGS

This review introduces new evidence on cognitive biases involved in the pathogenesis of schizophrenia and demonstrates how the MCT raises the patients' (metacognitive) awareness to detect and defuse such 'cognitive traps'. At the end, a new individualized variant entitled MCT+ is presented targeting individual delusional ideas. Finally, empirical results are summarized that speak in favour of the feasibility and efficacy of MCT.

SUMMARY

Recent studies assert marked cognitive biases in schizophrenia. MCT has evolved as a feasible and effective complement of standard psychiatric treatment.

A randomised controlled trial of cognitive behaviour therapy for psychosis in a routine clinical service

OBJECTIVE

To evaluate cognitive behaviour therapy for psychosis (CBTp) delivered by non-expert therapists, using CBT relevant measures.

METHOD

Participants (N = 74) were randomised into immediate therapy or waiting list control groups. The therapy group was offered 6 months of therapy and followed up 3 months later. The waiting list group received therapy after waiting 9 months (becoming the delayed therapy group).

RESULTS

Depression improved in the combined therapy group at both the end of therapy and follow-up. Other significant effects were found in only one of the two therapy groups (positive symptoms; cognitive flexibility; uncontrollability of thoughts) or one of the two time points (end of therapy: general symptoms, anxiety, suicidal ideation, social functioning, resistance to voices; follow-up: power beliefs about voices, negative symptoms). There was no difference in costs between the groups.

CONCLUSION

The only robust improvement was in depression. Nevertheless, there were further encouraging but modest improvements in both emotional and cognitive variables, in addition to psychotic symptoms.

Cognitive insight in non-psychiatric individuals and individuals with psychosis: an examination using the Beck Cognitive Insight Scale

An increasing number of studies have used the Beck Cognitive Insight Scale (BCIS) to understand the reasoning of individuals with psychotic disorders. Less is known, however, about "normal" levels of insight and how non-psychiatric individuals compare to those with psychosis. The present study examined the structure of the BCIS in a non-psychiatric population and made comparisons between the scores of non-psychiatric individuals and those with psychosis. Participants were 418 students at American universities and 93 outpatients at a VA Medical Center with SCID-confirmed diagnoses of schizophrenia or schizoaffective disorder. Confirmatory factor analysis supports the 2-factor, 15-item structure previously reported for the BCIS, with one factor called self reflectiveness and the other called self certainty. Reliability analyses suggest strong internal consistency and test-retest results. Further, the BCIS subscales and composite index reliably distinguished between non-psychiatric and patient groups, though receiver operating characteristic (ROC) analysis did not suggest a particular cutoff score for predicting patient status. These results suggest that the BCIS is a valid measure to use in a non-psychiatric population, and that it reliably distinguishes between non-psychiatric individuals and those with psychotic disorders.
