Predictors of clinical insight in first-episode psychosis: Different patterns in men and women

BackgroundWe aimed to explore gender-related differences in the associations of insight impairment with clinical symptoms, metacognition, and social cognition in psychosis. MethodsRegression analysis of several clinical insight dimensions was conducted on the data from 116 men and 56 women with first-episode psychosis. Various clinical symptoms and measures of metacognition and social cognition were entered as predictors. ResultsIn both men and women, delusions emerged as a strong predictor of all insight dimensions, and verbal hallucinations as a strong predictor of symptom relabelling. In men, certain negative symptoms as well as self-certainty, lack of self-reflectiveness, impaired theory of mind, attributional biases, and a jumping-to-conclusions bias were additional predictors of poor insight, while good insight was associated with depression, anxiety, avolition, blunted affect, and impaired emotional recognition. In women, poor insight was associated with a self-serving/externalising bias, impaired emotional recognition, and attention disorders. ConclusionsPoor insight in first-episode psychosis is strongly linked to deficits in metacognition and social cognition, with marked differences between men and women with respect to the specific skills involved in the impairment. Meanwhile, good insight is linked to a variety of affective manifestations in men. These findings suggest new avenues for more targeted cognitive interventions to improve clinical insight in psychosis.

Clinical insight in first-episode psychosis: Clinical, neurocognitive and metacognitive predictors

ObjectivePoor insight is a major problem in psychosis, being detrimental for treatment compliance and recovery. Previous studies have identified various correlates of insight impairment, mostly in chronic samples. The current study aimed to determine clinical, neurocognitive, metacognitive, and socio-cognitive predictors of insight in first-episode psychosis. MethodsRegression analyses of different insight dimensions were conducted in 190 patients with first-episode psychosis. Measures of clinical symptoms, neurocognition, metacognition, social cognition, and ‘jumping to conclusions’ bias were entered as predictors. ResultsDelusions, disorganisation, and certain negative symptoms were associated with unawareness in various domains, while depression was associated with greater awareness of illness. Deficit in theory of mind and self-reflective processes, as well as a ‘jumping to conclusions’ bias, contributed to poor insight. Several neuropsychological scores also contributed to this but their contribution was no longer observed in regression analyses that included all the previously identified clinical and cognitive predictors. A measure of perseverative errors was still associated with unawareness and misattribution of symptoms. ConclusionIn models that account for 28 % to 50 % of the variance, poor insight in first-episode psychosis is mainly associated with delusions and certain negative symptoms. At the cognitive level it does not appear to result from neuropsychological impairment but rather from altered reasoning bias and dysfunction in metacognitive processes. Therapeutic strategies specifically directed at these mechanisms could help improve the evolution of insight in first episode psychosis.

Clinical insight in first episode psychosis: the role of metacognition

Background Poor clinical insight has been commonly reported in those with First Episode Psychosis (FEP) and thought to be influenced by a range of factors, including neurocognition and symptoms. Clinical insight may be compromised as a result of alterations in higher-level reflective processes, such as metacognitive ability and cognitive insight. Aims To explore whether metacognitive ability and cognitive insight are associated with clinical insight while controlling for IQ, depression, and symptoms in FEP. Methods 60 individuals with FEP completed measures for clinical insight, metacognitive ability, cognitive insight, positive and negative symptoms, depression, and IQ. Results Higher levels of metacognitive ability were associated with better clinical insight, even when controlling for IQ, depression, positive and negative symptoms, and medication. Integration subscale of metacognitive ability was most strongly associated with clinical insight. Cognitive insight was associated with clinical insight when controlling for covariates. However, when including metacognitive ability and cognitive insight in the predictive model, only metacognitive ability was significantly related to clinical insight. Discussion Metacognitive ability, specifically the ability to describe one’s evolving mental state to provide a coherent narrative, was significantly related to clinical insight, independent of covariates, and may be a potentially important target for intervention in FEP.

Cognitive Insight in First-Episode Psychosis: Changes during Metacognitive Training

Background: Metacognitive training (MCT) has demonstrated its efficacy in psychosis. However, the effect of each MCT session has not been studied. The aim of the study was to assess changes in cognitive insight after MCT: (a) between baseline, post-treatment, and follow-up; (b) after each session of the MCT controlled for intellectual quotient (IQ) and educational level. Method: A total of 65 patients with first-episode psychosis were included in the MCT group from nine centers of Spain. Patients were assessed at baseline, post-treatment, and 6 months follow-up, as well as after each session of MCT with the Beck Cognitive Insight Scale (BCIS). The BCIS contains two subscales: self-reflectiveness and self-certainty, and the Composite Index. Statistical analysis was performed using linear mixed models with repeated measures at different time points. Results: Self-certainty decreased significantly (p = 0.03) over time and the effect of IQ was negative and significant (p = 0.02). From session 4 to session 8, all sessions improved cognitive insight by significantly reducing self-certainty and the Composite Index. Conclusions: MCT intervention appears to have beneficial effects on cognitive insight by reducing self-certainty, especially after four sessions. Moreover, a minimum IQ is required to ensure benefits from MCT group intervention.

Brain Structural Correlates of Metacognition in First-Episode Psychosis.

Metacognition is impaired in schizophrenia and is an important predictor of functional outcome, but the underlying neuropathology is not clear. Studies have implicated frontal regions and there is also some evidence that the hippocampus might play a pivotal role, but findings are inconsistent. We set out to more comprehensively investigate the neural underpinnings of insight in first-episode psychosis (FEP) using 2 metacognitive measures (the Beck Cognitive Insight Scale [BCIS]) and a perceptual metacognitive accuracy task alongside structural magnetic resonance imaging (MRI). We measured cortical thickness in insula and frontal regions, hippocampal (including subfield) volumes, hippocampal microstructure (using neurite orientation dispersion and density imaging [NODDI]), and fractional anisotropy in fornix. Relative to controls, FEP showed poorer metacognitive accuracy, thinner cortex in frontal regions and lower fornix integrity. In healthy controls (but not FEP), metacognitive accuracy correlated with cortical thickness in frontal cortex and insula. Conversely, in FEP (but not controls), metacognitive accuracy correlated with hippocampal volume and microstructural indices. Subicular hippocampal subregions were particularly implicated. No structural correlates of BCIS were found. These findings suggest that the neural bases of metacognition might differ in FEP: hippocampal (rather than frontal) integrity seems to be critical. Further, the use of objectively measured metacognitive indices seems to be a more powerful method for understanding the neurocircuitry of metacognition in FEP, which has the potential to inform therapeutic strategies and improve outcome in these patients.

Moderating role of cannabis use between insight and depression in early psychosis

BackgroundA high level of insight in first episode psychosis (FEP) is positively correlated to important prognostic factors such as medication adherence and functional outcome but is associated with increased depression level and suicidal behavior. AimsThis is the first study questioning the potential moderating role of cannabis use in the relationship between insight and depression one year after a FEP. MethodIn this prospective observational study, we enrolled 214 FEP patients who had provided informed consent and been referred to a specialized early psychosis program and followed for 36 months. A series of multivariate regression models were used. Baseline insight, medication adherence and cannabis use (level of use on a continuum) were entered as independent variables, while the PANSS (positive and negative), the MADRS and the SOFAS scores after one year were alternately selected as the dependent variable. ResultsWe found a three-way interaction term between cannabis use, insight and medication adherence on depression level one year after the entry into the program. A high level of insight was significantly associated with higher MADRS scores in patients with high cannabis use, while depression decreased in high-insight patients with low cannabis use. ConclusionsCannabis use continuation during the year following a first episode psychosis may play a significant role in the development or the maintenance of post-psychotic depression in patients who present with high level of insight and adherence to medication, stressing the need for specific therapeutic strategies in this subgroup of patients.

Cannabis Use as a Moderator of the Association Between Insight and Depression in Early Psychosis: Results From a Prospective Study

Background: A high level of insight in first episode psychosis (FEP) is positively correlated to important prognostic factors such as medication adherence and functional outcome but is associated with increased depression level and suicidal behavior. This is the first study questioning the potential moderating role of cannabis use in the relationship between insight and depression one year after a FEP. Methods: In this prospective observational study, we enrolled 214 FEP patients who had been referred to a specialized early psychosis program and followed for 36 months. A series of multivariate regression models were used. Baseline insight, medication adherence and cannabis use (level of use on a continuum) were entered as independent variables while the PANSS positive score, PANSS negative score, the MADRS score and the GAF score after one year were alternately selected as the dependent variable. Outcomes: We found a three-way interaction term between cannabis use, insight and medication adherence on depression level one year after the entry into the program. A high level of insight was significantly associated with higher MADRS scores in patients with high cannabis use, while depression decreased in high-insight patients with low cannabis use. Interpretation: Cannabis use continuation during the year following a first episode psychosis may play a significant role in the development or the maintenance of post-psychotic depression in patients who present with high level of insight and adherence to medication, stressing the need for specific therapeutic strategies in this subgroup of patients.

The right occipital lobe and poor insight in first-episode psychosis.

Lack of insight is a core feature of non-affective psychosis and has been associated with poorer outcomes. Brain abnormalities underlying lack of insight have been suggested, mostly in the frontal lobe, although previous research showed mixed results. We used a voxel-based morphometry (VBM) analysis in 108 first-episode non-affective psychosis patients to investigate the pattern of brain structural abnormalities related to lack of insight. In addition, 77 healthy volunteers were compared with the patients classified as having poor and good insight. The shortened version of the Scale to Assess Unawareness of Mental Disorder was used to evaluate insight. Patients with poor insight (n = 68) compared with patients with good insight (n = 40) showed a single significant cluster (kc = 5834; PcFWE = 0.001) of reduced grey matter volume (GMV) in the right occipital lobe extending to its lateral and medial surfaces, the cuneus, and the middle temporal gyrus. In addition, GMV at this cluster showed a negative correlation with the score of the SUMD (r = -0.305; p = 0.001). When comparing patients with poor insight with healthy subjects overall reductions of GMV were found, mainly in frontal and occipital lobes. Hence, poor insight in non-affective psychosis seems to be associated with specific brain abnormalities in the right occipital and temporal cortical regions. Dysfunction in any combination of these areas may contribute to lack of insight in non-affective psychosis. Specifically, the ‘right’ hemisphere dysfunction underlying impaired insight in our sample is consistent with previously reported similarities between lack of insight in psychosis and anosognosia in neurological disorders.

Targeting Insight in First Episode Psychosis: A Case Study of Metacognitive Reflection Insight Therapy (MERIT)

One aspect of schizophrenia contributing to its complexity is the lack of insight individuals often have into their illness. While poor insight is prevalent throughout the course of the illness, more severe levels are associated with first-episode psychosis (FEP). Interventions addressing insight are necessary but current treatments have been shown to have limited effectiveness. Thus, a novel intervention, Metacognitive Reflection and Insight Therapy (MERIT), is being studied for its efficacy of improving insight in individuals with schizophrenia spectrum disorders. MERIT is an integrative metacognitive therapy consisting of eight elements to assist clients in improving their ability to form complex ideas about themselves and others and to use this knowledge to respond to psychological problems. The present study is a case illustration of the implementation of MERIT to improve insight in FEP. Clinical outcomes were assessed and results showed that the client improved in both metacognition and insight. With replication, these results suggest that integrative metacognitive psychotherapy may serve as an intervention that improves insight in FEP, which marks an important step toward improved interventions for individuals with psychosis.

Predictors of Relapse and Functioning in First-Episode Psychosis: A Two-Year Follow-Up Study.

First-episode psychosis has an annual incidence rate of 24.6 to 40.9 per 100,000 population, and most individuals develop chronic disorders, such as schizophrenia or affective psychosis. The first two to five years are thought to be key determinants of long-term functional and clinical prognosis. This study aimed to determine the two-year course of illness in first-episode psychosis, including diagnosis, relapse, and functioning and factors related to these variables. A total of 140 patients who experienced a first episode of psychosis were recruited and evaluated between 2008 and 2012 in a first-episode psychosis program in Barcelona, Spain. Regression models were used to determine factors predicting relapse and functioning. A general trend was noted toward improved functioning and less severe psychotic symptoms. However, after two years, one-third of the patients had a diagnosis of schizophrenia and more than 40% had a diagnosis of affective psychosis. Rates of relapse were 31% after one year and 43% at two years. Cannabis use after illness onset and poor insight were the best predictors of relapse. Being male and severity of negative symptoms at baseline predicted worse functioning at two years. Patients with first-episode psychosis were found to have high relapse rates during the first years after illness onset. Further studies evaluating treatment strategies focused on reducing cannabis use and improving insight in first-episode psychosis should be encouraged.

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.

Insight and suicidality in first‐episode psychosis: understanding the influence of suicidal history on insight dimensions at first presentation

Lack of insight is a cardinal feature of psychosis with crucial implications for outcome. Concerns have been raised regarding a link between insight and suicidality. This study aimed to test the relationship between suicidal behaviour preceding first-episode psychosis (FEP) and insight dimensions at treatment onset. A total of 112 FEP inpatients were recruited. Suicidal events prior to admission were recorded. Insight was assessed multidimensionally with the Schedule for the Assessment of Insight - Expanded version shortly after admission. Suicidal and non-suicidal patients were compared regarding scores on 'total insight' and three insight domains: 'awareness of mental illness', 'relabeling of psychotic experiences as abnormal' and 'compliance'. This analysis was also adjusted for a set of sociodemographic, clinical, neurocognitive and psychopathological variables. Bivariate analyses demonstrated a direct association between previous suicidality and all insight domains. However, these associations did not survive multivariable regression models, which demonstrated gender (female), shorter duration of untreated psychosis (DUP) and psychopathological symptoms - depression and disorganization - to mediate the influence of suicidal history on insight, and therefore to underlie the latter. Insight dimensions in FEP patients are influenced by having suicidal antecedents through some mediating variables such as gender, DUP and depression. Further prospective studies are needed to clarify the potential implications of these findings on the management of insight in FEP. As suicidal history is associated with greater levels of both depression and insight at first presentation, these three variables might be useful in predicting further suicidal events.

P.3.e.008 Cannabis use moderates the relation between cognitive reserve and insight in first-episode psychosis: a longitudinal study

Background: The Beck Depression Inventory BDI is the most often used self-rating instrument for depressive symptoms. In the present study, the BDI was compared with a self-rating version of the Montgomery Åsberg Depression Rating Scale (MADRS-S) in 86 psychiatric patients with mainly affective and anxiety disorders. Methods: The patients were interviewed with the SCID-I Interview for a DSM-IV Major depression, and self-assessed the BDI and the MADRS. They were rated to have either mild, moderate or severe depressive symptomatology. After recovery, criteria for DSM-IV Personality disorders were self-assessed. Results: The instruments were about equal in differentiating between different Axis-I diagnoses and did not differ according to sensitivity to change during antidepressive treatment. Although the scales were highly intercorrelated (r=0.869), the BDI was demonstrated to tap more maladaptive personality traits compared to the MADRS-S. Limitations: Because the sample consisted of psychiatric patients with prominent psychiatric symptomatology, the discriminative power of the BDI and the MADRS-S should be further evaluated in a sample with milder symptoms. Conclusions: The MADRS-S is equivalent to the BDI as a self-assessment instrument for depression, but the MADRS-S focuses on core depressive symptoms, and is less influenced by maladaptive personality traits.

Are there specific neuropsychological deficits underlying poor insight in first episode psychosis?

Insight in psychosis is a multi-dimensional phenomenon, and has been hypothesised to have some sort of neuropsychological basis. It is unclear to what extent specific neuropsychological abilities are able to predict insight beyond the effect of generalised cognitive ability. We aimed to test this association, alongside the relationship of insight with illness duration and diagnosis, in a sample of first episode psychosis patients. 110 first episode psychosis patients were recruited and a comprehensive assessment was administered, including insight, symptoms, diagnosis and neuropsychological function. Low insight was related to worse performance in a variety of neuropsychological tasks. Regression analysis tested whether any specific tasks were related to insight (or dimensions of insight) beyond the effect of IQ. Verbal memory had an effect on total insight and all dimensions of insight (except compliance) beyond the effect of IQ. Insight appeared to vary with diagnosis, with those diagnosed with depressive affective psychoses having better insight than those with manic affective psychoses. There was no relationship between insight and DUP, but there was a relationship between time spent in treatment before assessment and insight, even after controlling for severity of symptoms. These results suggest a model of insight in early psychosis with a significant neuropsychological component, particularly with verbal memory but also with generalised cognitive ability. There is likely to be a social component to insight affected by initial time spent in contact with treatment, helping patients to understand and come to terms with their illness.

Cortical thickness is associated with poor insight in first-episode psychosis

Through conceptualizing poor insight in psychotic disorders as a form of anosognosia (neurological deficit), frontal lobe dysfunction is often ascribed a vital role in its pathogenesis. Whether non-frontal brain regions are important for insight remains to be investigated. We used a multi-method approach to examine the neural morphometry of all cortical regions for insight in first-episode psychosis. Insight was rated in 79 people with a first-episode psychosis with the awareness of illness and awareness of treatment need and efficacy items of the Scale for assessment of Unawareness of Mental Disorder. Participants were assessed with magnetic resonance imaging. Cortical thickness analysis and voxel-based morphometry were utilized to identify the possible neuroanatomical basis of insight. Cortical thickness technique revealed that poorer awareness of illness was associated with regional thinning in left middle frontal and inferior temporal gyri. Poorer awareness of treatment need and efficacy was associated with cortical thinning in left medial frontal gyrus, precuneus and temporal gyri. No significant associations emerged between any insight measure and gray matter density using voxel-based morphometry. The results confirm predictions derived from the anosognosia/neuropsychology account and assert that regional thickness in frontal cortex is associated with awareness of illness in the early phase of psychosis. The fact that prominent thickness reductions emerged in non-frontal regions of the brain in parietal and temporal cortices for both awareness of illness and awareness of treatment need and efficacy suggests that the neural signature of insight involves a network of brain structures, and not only the frontal lobes as previously suggested.

Premorbid Personality and Insight in First-Episode Psychosis

Insight in psychosis and schizophrenia is considered a complex biopsychosocial phenomenon. Premorbid personality is regarded by some authors as part of the substrate to many psychiatric phenomena, but it is not clear if this applies to insight. To examine longitudinal relationships between personality traits and insight dimensions in first-episode psychosis. One hundred consecutive antipsychotic-naïve first-episode nonaffective psychotic patients admitted to hospital were included in the study. Eighty-one patients completed at 1 month a premorbid personality evaluation, plus baseline, and 6-month insight assessments. We used the Assessment and Documentation of Psychopathology inventory for assessing insight dimensions (not feeling ill, lack of insight, and refusal of treatment) and the Personality Assessment Schedule for ascertaining 5 dimensions of premorbid personality (schizoid, passive-dependent, anancastic, sociopathic, and schizotypy). At baseline, personality dimensions did not show any association with insight dimensions, with the exception of schizotypy traits. At 6 months, schizoid and sociopathic personality showed a significant association with not feeling ill (r = .30, P ≤ .007; r = .27, P = .01) and lack of insight (r = .36, P = .001; r = .41, P < .001), respectively. When we calculated insight change, schizoid and sociopathic personality had moderate correlation with the lack of insight dimension (r = -.34, P = .002; r = .38, P < .001, respectively). After applying partial correlations for potential confounders and Bonferroni correction, the associations remained significant. Moreover, using a regression model, sociopathic and schizoid personality significantly predicted lack of insight at 6 months and change from baseline to the 6 months assessment. Sociopathic and schizoid personality dimensions were not only significantly associated with lack of insight at 6 months but also predicted change on lack of insight over 6 months. Therefore, exploring premorbid personality traits at the beginning of a psychotic episode may be helpful in identifying patients at high risk for lack of insight during the initial course of the illness.

Longitudinal changes of insight in first episode psychosis and its relation to clinical symptoms, treatment adherence and global functioning: One-year follow-up from the Eiffel study

Objectives The Eiffel study is a longitudinal, naturalistic study of patients with first episode psychosis (FEP) designed to evaluate the predictive value of defective insight on treatment adherence and global functioning. Methods Five hundred seventy-seven patients with FEP were assessed at baseline and at a 1-year follow-up. They were compared in terms of sociodemographic factors, psychopathology, insight, treatment adherence and functional outcome. Longitudinal functionality was prospectively assessed with the clinical global impression (CGI) and global assessment of functioning (GAF) rating scales. Results At baseline, up to 50% of our sample presented with a lack of insight. Most clinical symptoms, including insight, improved over the follow-up period. Insight, education and social withdrawal significantly predicted CGI and GAF at follow-up. Insight and level of education were predictive of treatment adherence. Conclusions Insight significantly predicted the general clinical course, treatment adherence and functional outcome in our FEP sample after 1 year. Only education additionally accounted for the longitudinal course. Since our results suggest that better insight improves treatment adherence and consequently clinical course and functional outcome, insight could be a specific target of treatment in early intervention programs.

Insight in first episode psychosis: Conceptual and clinical considerations

Background and Objectives: Poor insight or impaired awareness of illness is a very common feature in psychosis. The purpose of this study is to review critically the conceptual approximations from different perspectives to insight in psychosis and address its relations to other clinical and psychopathological variables. Methods: We reviewed the principal factors that have been proposed to contribute to deficient insight in first episode psychosis patients from different conceptual frameworks, defence mechanisms or coping styles, structural or volumetric brain associations, cognitive deficits, and severity of clinical symptoms. Results: This review of literature suggests that insight is a complex mental faculty heavily influenced by additional factors, such as social and cultural aspects, among others. Results also show the correlates of insight in first episode psychosis and treatment adherence in the course of the illness, although it is not stable over time. In fact, adequate level of insight is a necessary, but not sufficient condition for an adequate adherence. Conclusions: Insight is a complex and multidimensional mental faculty that is a key factor in the prognosis of the illness. The link between both is probably mediated by the interaction of additional variables such as DUP, affective symptoms, sociodemographics, and drug abuse. Due to the complex relationships among insight, cognition and psychopathology in psychosis, these three factors could be considered as semi-independent phenomena. Finally, the neuroscience perspective about insight in psychosis is an especially productive research line that has contributed to a better understanding of the complex picture.

Manic and depressive symptoms and insight in first episode psychosis

Insight impairment is common early in the course of psychosis. Most studies have focused on the relationship between insight and depression, although manic symptoms are also frequent in psychoses. The main aim of this study was to examine the relationship between insight dimensions and manic and depressive symptoms in first-episode psychosis. A group of inpatients in their first psychotic episodes (n=124) were evaluated using the Scale to Assess Unawareness of Mental Disorder, Young Mania Rating Scale and Hamilton Depression Rating Scale. To study the effect of clinical, manic and depressive symptoms on insight, awareness of mental disorder, awareness of the achieved effects of medication, and awareness of the social consequences of having a mental disorder were modelled using ordinal logistic regression techniques. Results showed that greater awareness of mental disorder was significantly related to higher age at first episode together with higher scores for negative and depressive symptoms. The opposite was found to be true in presentations with a higher severity of disease and manic symptoms. The model fitting unawareness of the achieved effects of medication identified the same significant variables, except in the case of negative symptoms. Finally, the model assessing the social consequences of having a mental disorder showed unawareness to be greater when manic symptoms and disease severity were high.
