Emotional intelligence in schizophrenia

A multidimensional assessment of social cognition in psychometrically defined schizotypy

Individuals with schizophrenia exhibit impairments in multiple social cognitive domains. There is evidence that these impairments may be trait-related vulnerability markers for schizophrenia. However, the literature focusing on individuals vulnerable to developing schizophrenia-spectrum disorders, referred to as schizotypy, has produced inconsistent findings. This study's primary aim was to provide a more comprehensive understanding of social cognitive functioning within schizotypy than previous studies by employing a broad array of measures to assess multiple social cognitive domains, and examine how these domains relate to specific schizotypy traits (i.e., positive, negative, and disorganized) and Quality of Life (QOL). Facial emotion recognition, Theory of Mind (ToM), and aspects of emotional intelligence related to regulating one's own emotions (emotion management) and other's emotions (social management) were measured. Individuals with psychometrically defined schizotypy (n=36) and controls (n=26) were examined. The schizotypy group performed significantly worse than controls on facial emotion recognition, ToM, and emotion management, but not social management. Generally speaking, poorer social cognition performance was not a function of specific schizotypy traits. However, negative traits were associated with poorer facial emotion recognition, and disorganized traits were associated with better social management. Facial emotion recognition was associated with QOL in the schizotypy group.

Impaired emotion regulation in schizophrenia: evidence from event-related potentials

BACKGROUND

Although several aspects of emotion seem to be intact in schizophrenia, there is emerging evidence that patients show an impaired ability to adaptively regulate their emotions. This event-related potential (ERP) study examined whether schizophrenia is associated with impaired neural responses to appraisal frames, that is when negative stimuli are presented in a less negative context.

METHOD

Thirty-one schizophrenia out-patients and 27 healthy controls completed a validated picture-viewing task with three conditions: (1) neutral pictures preceded by neutral descriptions ('Neutral'), (2) unpleasant pictures preceded by negative descriptions ('Preappraised negative'), and (3) unpleasant pictures preceded by more neutral descriptions ('Preappraised neutral'). Analyses focused on the late positive potential (LPP), an index of facilitated attention to emotional stimuli that is reduced following cognitive emotion regulation strategies, during four time windows from 300 to 2000 ms post-picture onset.

RESULTS

Replicating prior studies, controls showed smaller LPP in Preappraised neutral and Neutral versus Preappraised negative conditions throughout the 300-2000-ms time period. By contrast, patients showed (a) larger LPP in Preappraised neutral and Preappraised negative versus Neutral conditions in the initial period (300-600 ms) and (b) an atypical pattern of larger LPP to Preappraised neutral versus Preappraised negative and Neutral conditions in the 600-1500-ms epochs.

CONCLUSIONS

Modulation of neural responses by a cognitive emotion regulation strategy seems to be impaired in schizophrenia during the first 2 s after exposure to unpleasant stimuli.

Adapting and evaluating a social cognitive remediation program for schizophrenia in Arabic

Although growing evidence supports the efficacy of social cognitive training interventions for schizophrenia, nearly all studies to date have been conducted in Westernized countries. In the current study, we translated and adapted an existing social cognitive skills training (SCST) program into Arabic and conducted a preliminary efficacy evaluation in schizophrenia outpatients in Egypt. Twenty-two patients were randomized to 16 sessions of group-based SCST and 20 were randomized to a format- and time-matched illness management training control condition. Pre- and post-intervention assessments included a primary social cognition outcome measure that assessed four branches of emotional intelligence and a battery of neurocognitive tests. The SCST group demonstrated significant treatment effects on total emotional intelligence scores (F=24.31, p<.001), as well as the sub-areas of Identifying Emotions (F=11.77, p<.001) and Managing Emotions (F=23.27, p<.001), compared with those in the control condition. There were no treatment benefits for neurocognition for either condition, and both interventions were well-tolerated by patients. These initial results demonstrate the feasibility of implementing social cognitive interventions in different cultural settings with relatively minor modifications. The findings are encouraging regarding further efforts to maximize the benefits of social cognitive interventions internationally.

Metacognition-oriented social skills training for individuals with long-term schizophrenia: methodology and clinical illustration

PURPOSE

There is much evidence indicating the presence of social deficits in schizophrenia and the detrimental effect of these deficits on global functioning in this population. As a result, social skills training (SST) has emerged as a legitimate psychosocial treatment, although effectiveness research has revealed small effect sizes and limited generalizability regarding the benefits of this treatment.

METHODS

In light of the strong evidence of metacognitive deficits in schizophrenia and the importance of metacognition to successful social functioning, we propose a novel therapeutic intervention wherein metacognitive remediation is integrated into SST: metacognition-oriented social skills training (MOSST). In the current paper, we present MOSST, an adapted SST programme wherein clients are also encouraged to have mindful contact with their own thoughts and to better consider and understand the mental states of others as well as the connection between mental states and behaviour.

RESULTS

We present a case wherein an individual with schizophrenia successfully completed the MOSST programme.

CONCLUSION

We outline directions for future research, starting with the logical next step of empirically testing the efficacy of MOSST.

KEY PRACTITIONER MESSAGE

Currently social skills training is considered to be the elected psychosocial treatment for people affected by schizophrenia, although evidence indicates limited benefits. People with schizophrenia have metacognitive deficits, which interfere with proper social functioning. A metacognitive-oriented social skills training (MOSST) intervention has been developed by the authors.A treatment such as MOSST, which integrates social skills training and metacognitive training, promises to improve social skills through improving the metacognition.

Emotional memory modulation in schizophrenia: an overview

OBJECTIVE

In healthy controls, the emotional charge of stimuli influences how well stimuli are remembered. Although patients with schizophrenia (SCZ) have deficits in memory and in emotional processing, studies on emotional memory modulation (EMM) in SCZ report contradictory results. The aim of this review was to investigate whether methodological differences could explain these contradictory results.

METHOD

We reviewed the literature to investigate whether task differences could explain these differences. Due to the methodological differences, a meta-analysis was not possible.

RESULTS

Fourteen studies were identified that used a total of 22 tasks to study EMM in patients with SCZ. Two-thirds of the tasks showed no differences in EMM between patients with SCZ and healthy controls. Differences in EMM were found more often when long-term compared to short-term memory was measured, when memory instructions were implicit instead of explicit and when stronger emotional stimuli were used. An overall memory deficit or the mode of retrieval was not related to EMM.

CONCLUSION

Deficits in EMM in long-term compared to short-term memory point toward impaired emotional modulation of memory consolidation. Reduced EMM on implicit, but not explicit, tasks suggests a deficit in unconsciously using emotional content to modulate memory.

Social and nonsocial cognition in bipolar disorder and schizophrenia: relative levels of impairment

OBJECTIVE

This study aimed to determine the relative extent of impairment in social and nonsocial cognitive domains in patients with bipolar disorder compared with schizophrenia patients and healthy comparison subjects.

METHODS

Sixty-eight clinically stable outpatients with bipolar disorder, 38 clinically stable outpatients with schizophrenia, and 36 healthy comparison subjects completed a range of social (facial affect perception, emotional regulation, empathic accuracy, mental state attribution, and self-referential memory) and nonsocial (speed of processing, attention/vigilance, working memory, verbal memory, visual memory, and reasoning/problem solving) cognitive tasks.

RESULTS

For each social cognitive task, patients with bipolar disorder did not differ significantly from comparison subjects, and both groups performed better than schizophrenia patients. Within the bipolar group, clinical features and medication status were not related to social cognitive performance. Bipolar patients showed performance patterns across tasks (i.e., profiles) that were similar to those of comparison subjects on both social and nonsocial cognitive domains, whereas both groups differed from schizophrenia patients for both domains. Regarding relative impairment across the two cognitive domains, results revealed a significant group-by-domain interaction in which bipolar patients showed less impaired social than nonsocial cognition, while schizophrenia patients showed the opposite pattern.

CONCLUSIONS

Bipolar patients showed less impairment on social relative to nonsocial cognitive performance, whereas schizophrenia patients showed more impairment on social relative to nonsocial cognitive performance. These results suggest that these two cognitive domains play different roles in bipolar disorder compared with in schizophrenia.

From perception to functional outcome in schizophrenia: modeling the role of ability and motivation

CONTEXT Schizophrenia remains a highly disabling disorder, but the specific determinants and pathways that lead to functional impairment are not well understood. It is not known whether these key determinants of outcome lie on 1 or multiple pathways. OBJECTIVE To evaluate theoretically based models of pathways to functional outcome starting with early visual perception. The intervening variables were previously established determinants of outcome drawn from 2 general categories: ability (ie, social cognition and functional capacity) and beliefs/motivation (ie, defeatist beliefs, expressive and experiential negative symptoms). We evaluated an integrative model in which these intervening variables formed a single pathway to poor outcome. DESIGN This was a cross-sectional study that applied structural equation modeling to evaluate the relationships among determinants of functional outcome in schizophrenia. SETTING Assessments were conducted at a Veterans Administration Medical Center. PARTICIPANTS One hundred ninety-one clinically stable outpatients with schizophrenia or schizoaffective disorder were recruited from the community. RESULTS A measurement model showed that the latent variables of perception, social cognition, and functional outcome were well reflected by their indicators. An initial untrimmed structural model with functional capacity, defeatist beliefs, and expressive and experiential negative symptoms had good model fit. A final trimmed model was a single path running from perception to ability to motivational variables to outcome. It was more parsimonious and had better fit indices than the untrimmed model. Further, it could not be improved by adding or dropping connections that would change the single path to multiple paths. The indirect effect from perception to outcome was significant. CONCLUSIONS The final structural model was a single pathway running from perception to ability to beliefs/motivation to outcome. Hence, both ability and motivation appear to be needed for community functioning and can be modeled effectively on the same pathway.

Clinical instruments to evaluate and guide treatment in schizophrenia

Treatment research in schizophrenia is focused on the development of pharmacological agents that are effective for improving community functioning and decreasing disability. As a result of this recent focus, there has been substantial activity for developing instruments that can measure functioning as well as the psychopathological domains that are related to functioning. Issues in selecting measures of real-world functioning include ensuring that the instrument measures the full range of possible outcomes and differentiating symptoms from functioning. For many treatment studies it is unrealistic to expect a change in actual functioning. Most treatment trials are too brief to permit subjects to change their level of vocational or social functioning. In addition, real-world functioning is influenced by factors such as an individual's financial status or the availability of community services. This has led to the use of functional capacity measures which monitor an individual's ability to perform functionally meaningful tasks even if they do not complete these tasks. Attention has also focused on interview-based measures of cognition and negative symptoms. Both of these psychopathological domains are related to functioning and both are the focus of drug development.Recent drug development has focused on the development of agents that target domains of psychopathology that may lead to improved functioning. This focus contrasts with the development of first and second-generation antipsychotics; these drugs were considered effective when they treated psychotic symptoms such as auditory hallucinations, suspiciousness, delusions, and disorganized behaviors. Treating these symptoms was important for reducing suffering and for allowing many patients to live in their communities. On the other hand, these agents had relatively modest effects on the ability of patients to function in their communities. This new focus on functioning has led to the development of new instruments for measuring functioning as well as the psychopathological domains that appear to be related to impaired functioning. This review will discuss the challenges that instrument developers have faced in designing these new instruments as well as the current state of the field. The measurement of typical psychopathology-particularly psychosis will not be discussed.

Structural neurobiological correlates of Mayer-Salovery-Caruso Emotional Intelligence Test performance in early course schizophrenia

OBJECTIVE

The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) is a key measure of social cognition in schizophrenia that has good psychometric properties and is recommended by the MATRICS committee. As a way to further investigate the validity of the MSCEIT, this study sought to examine the neurobiological correlates of MSCEIT performance in patients with early course schizophrenia.

METHODS

A total of 51 patients diagnosed with early course, stabilized schizophrenia or schizoaffective disorder completed structural magnetic resonance imaging (MRI) scans and the MSCEIT. Investigation of the associations between MSCEIT performance and gray matter morphology was examined by conducting voxel-based morphometry (VBM) analyses across hypothesized social-cognitive regions of interest using automated anatomical labeling in Statistical Parametric Mapping Software, version 5 (SPM5). All VBM analyses utilized general linear models examining gray matter density partitioned images, adjusting for demographic and illness-related confounds. VBM results were then followed up with confirmatory volumetric analyses.

RESULTS

Patients with poorer overall and Facilitating, Understanding, and Managing Emotions subscale performances on the MSCEIT showed significantly reduced gray matter density in the left parahippocampal gyrus. Additionally, attenuated performance on the Facilitating and Managing Emotions subscales was significantly associated with reduced right posterior cingulate gray matter density. All associations observed between MSCEIT performance and gray matter density were supported with confirmatory gray matter volumetric analyses, with the exception of the association between the right posterior cingulate and the facilitation of emotions.

CONCLUSION

These findings provide additional evidence for the MSCEIT as a valid social-cognitive measure by elucidating its correlates with neurobiological structures commonly implicated in emotion processing. These findings provide additional biological evidence supporting the use of the MSCEIT in cognitive enhancing clinical trials in schizophrenia.

Emotion recognition impairment is present early and is stable throughout the course of schizophrenia

Individuals with schizophrenia experience problems in the perception of emotion throughout the course of the disorder. Few studies have addressed the progression of the deficit over time. The present investigation explores face emotion recognition (FER) performance throughout the course of schizophrenia. The aim of the study was to test the hypotheses that: 1) FER impairment was present in ultra high-risk (putatively prodromal) individuals, and that 2) impairment was stable across the course of the illness. Forty-three individuals with a putative prodromal syndrome, 50 patients with first episode of schizophrenia, 44 patients with multi-episode schizophrenia and 86 unaffected healthy control subjects were assessed to examine emotion recognition ability. ANCOVA analysis adjusted for possible confounder factors and subsequent planned contrasts with healthy controls was undertaken. The results revealed deficits in recognition of sadness and disgust in prodromal individuals, and of all negative emotions in both first-episode and multi-episode patients. Furthermore, there were no significant differences between clinical groups. Within the framework of the neurodevelopmental model of schizophrenia, our results suggest the presence of emotional recognition impairment before the onset of full-blown psychosis. Moreover, the deficit remains stable over the course of illness, fitting the pattern of a vulnerability indicator in contrast to an indicator of chronicity or severity.

Cognitive motivations of free riding and cooperation and impaired strategic decision making in schizophrenia during a public goods game

Schizophrenia is generally characterized by various positive and negative symptoms that are accompanied by significant social dysfunction. Various researchers investigated the functional impairments in schizophrenia including impaired theory of mind (TOM), poor integration of affective and cognitive information, and malfunctioning of adaptive and strategic learning process. However, most of the studies were limited to simplified cognitive tests or computerized choice games that exclude real social interaction. The aim of the current study was to investigate human strategies based on the incentives and particularly the cognitive and emotional motivations of free riding. We examined the decision patterns of 41 healthy subjects (HSs) and 37 schizophrenia patients (SZ) during the public goods game (PGG), one of the games simulating human cooperation and free riding in group interactions. Strategic decision processes during the iterative binary PGG were assessed in terms of cognitive understanding, loss sensitivity, and TOM. We found that greed and loss sensitivity both motivated free-riding behavior in the HS, but that they were more vulnerable to greedy incentives than to possible loss. More significantly, the SZ clearly displayed a lower prevalence of free riding and distinct decision patterns from HS. Nonstrategic and unexpectedly low free ridings in the SZ likely arise from poor integration of cognitive and affective information. We suggest that loss sensitivity and TOM as well as cognitive understanding are involved in regulation of the free riding and cooperative behavior.

Perceived emotional intelligence and clinical symptoms in mental disorders

Research in emotional regulation has revealed that difficulties in the use and processing of affective information constitute a key factor in most mental disorders. To evaluate perceived emotional intelligence (PEI) deficits in patients with diverse psychopathological disorders and their relationship with clinical symptoms. Differences in PEI have been identified between a clinical group (n = 163) and a group of non-clinical individuals (n = 163). In the clinical group, the patients met DSM diagnostic criteria for one of the following: anxiety disorder, mood disorder, substance abuse disorder, psychotic disorder or borderline personality disorder. The PEI and clinical symptoms were assessed using the Spanish version of the TMMS-24 and the SCL-90-R, respectively. Patients from clinical group show higher levels of attention to feelings, but lower scores in abilities to manage effectively their negative emotional states compared to participants from non-clinical control group. Similarly, significant differences in PEI levels between different diagnostic groups were found. Our study provides preliminary evidence that deficits in PEI are related to the presence and severity of clinical symptoms in patients with different mental disorders.

A video ethnography approach to assessing the ecological validity of neurocognitive and functional measures in severe mental illness: results from a feasibility study

BACKGROUND

The ecological validity of neurocognitive and functional measures in severe mental illness is poorly understood because of a lack of validated research methods to study community life-as-lived. We describe the development of a video ethnography method that measures naturalistic behaviors with codes called community performance indicators (CPIs). The method could provide a strategy to test the ecological validity of neurocognitive and functional assessments.

METHODS

We gathered up to 18.5 hours of video ethnography data on each of 9 subjects with schizophrenia selected for high or low composite scores on the MATRICS Consensus Cognitive Battery (MCCB). We used video ethnography to capture subjects' everyday behaviors in their usual environments. We established 4 CPIs that showed excellent inter-rater and promising test-retest reliability: (1) behavioral activity level, (2) goal pursuit, (3) social interaction, and (4) problem solving.

RESULTS

(1) High and low MCCB subjects showed statistically significantly differences on all 4 CPIs. (2) MCCB composite scores were correlated with all 4 CPIs (r = .54 to -.77, P < .01 to .07). (3) The MCCB domain scores demonstrated some specificity in their correlations with the CPIs; eg, verbal learning, reasoning/problem solving, and social cognition were correlated with CPI domains of social interaction and problem solving.

CONCLUSIONS

We present a method for reliably measuring everyday functional performance in schizophrenia. Results from a small select sample suggest that CPIs capture skills associated with neurocognition, supporting their use in a larger study of ecological validity.

Measuring Emotional Intelligence in Early Adolescence With the MSCEIT-YV

Emotional intelligence (EI) theory provides a framework to study the role of emotion skills in social, personal, and academic functioning. Reporting data validating the importance of EI among youth have been limited due to a dearth of measurement instruments. In two studies, the authors examined the reliability and validity of the Mayer–Salovey–Caruso Emotional Intelligence Test—Youth Version (MSCEIT-YV), a performance test of EI. Study 1 examined psychometric attributes of the MSCEIT-YV in a large sample of fifth- to eighth-grade students ( N = 756). Study 2 examined the relationship of the MSCEIT to student and teacher reports of academic, social, and personal functioning among fifth- and sixth-grade students ( N = 273). The authors report that EI can be measured reliably with the MSCEIT-YV and that higher scores on the test are related to healthier psychological functioning and greater social competence based on both teacher and student ratings, as well as to academic performance in English language arts.

Factor structure of emotional intelligence in schizophrenia

Social cognition, which includes emotional intelligence, is impaired in schizophrenia. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) is a widely-used assessment of emotional intelligence, with a four-factor structure in healthy individual. However, a recent factor analysis in schizophrenia patients revealed a two-factor structure of the MSCEIT. The current study aimed to replicate this finding in a larger, more diverse, schizophrenia sample (n=194). Our findings revealed an identical two-factor structure as in the previously-reported study, indicating that emotional intelligence is organized in a different manner in schizophrenia than it is in healthy controls.

Social cognition in schizophrenia, Part 2: 12-month stability and prediction of functional outcome in first-episode patients

This study evaluated the longitudinal stability and functional correlates of social cognition during the early course of schizophrenia. Fifty-five first-episode schizophrenia patients completed baseline and 12-month follow-up assessments of 3 key domains of social cognition (emotional processing, theory of mind, and social/relationship perception), as well as clinical ratings of real-world functioning and symptoms. Scores on all 3 social cognitive tests demonstrated good longitudinal stability with test-retest correlations exceeding .70. Higher baseline and 12-month social cognition scores were both robustly associated with significantly better work functioning, independent living, and social functioning at the 12-month follow-up assessment. Furthermore, cross-lagged panel analyses were consistent with a causal model in which baseline social cognition drove later functional outcome in the domain of work, above and beyond the contribution of symptoms. Social cognitive impairments are relatively stable, functionally relevant features of early schizophrenia. These results extend findings from a companion study, which showed stable impairments across patients in prodromal, first-episode, and chronic phases of illness on the same measures. Social cognitive impairments may serve as useful vulnerability indicators and early clinical intervention targets.

Social cognition in schizophrenia, Part 1: performance across phase of illness

Social cognitive impairments are consistently reported in schizophrenia and are associated with functional outcome. We currently know very little about whether these impairments are stable over the course of illness. In the current study, 3 different aspects of social cognition were assessed (emotion processing, Theory of Mind [ToM], and social relationship perception) at 3 distinct developmental phases of illness: prodromal, first episode, and chronic. In this cross-sectional study, participants included 50 individuals with the prodromal risk syndrome for psychosis and 34 demographically comparable controls, 81 first-episode schizophrenia patients and 46 demographically comparable controls, and 53 chronic schizophrenia patients and 47 demographically comparable controls. Outcome measures included total and subtest scores on 3 specialized measures of social cognition: (1) emotion processing assessed with the Mayer-Salovey-Caruso Emotional Intelligence Test, (2) ToM assessed with The Awareness of Social Inference Test, and (3) social relationship perception assessed the Relationships Across Domains Test. Social cognitive performance was impaired across all domains of social cognition and in all clinical samples. Group differences in performance were comparable across phase of illness, with no evidence of progression or improvement. Age had no significant effect on performance for either the clinical or the comparison groups. The findings suggest that social cognition in these 3 domains fits a stable pattern that has outcome and treatment implications. An accompanying article prospectively examines the longitudinal stability of social cognition and prediction of functional outcome in the first-episode sample.

A meta-analysis of emotion perception and functional outcomes in schizophrenia

INTRODUCTION

Emotion perception (EP) is impaired in schizophrenia, is stable across clinical state, resistant to antipsychotic treatment and linked to symptom severity. Given its pervasive nature, there is a need to quantitatively examine whether this dysfunction impacts functional outcomes. We used a meta-analytic strategy to combine results from several studies and examine synthesized effect sizes.

METHODS

A Meta-analysis of Observational Studies in Epidemiology standard was used to extract data following a PubMed and PsychInfo search. Studies reporting correlations between measures of EP and functional outcomes in schizophrenia spectrum disorders were selected. The impact of potential methodological (task type), demographic (sex, age, race, education, marital status) and clinical (age of onset, duration of illness, setting, symptoms, anti-psychotic medication) moderators on effect sizes were examined.

RESULTS

Twenty-five studies met inclusion criteria and included 1306 patients who were 37 years old, with 12 years of education, 64% male and 63% Caucasian. There was a significant relationship between EP and functional outcomes in individuals with schizophrenia or schizoaffective disorder, with effect sizes in the medium range. Medium to large range positive correlations were observed between emotion identification and functional outcome domains involving social problem solving, social skills and community functioning. Significant moderators included task type (emotion identification tasks), sex (% male in sample), race (% Caucasian in sample) and clinical symptoms (negative and positive).

CONCLUSIONS

Emotion identification deficits are associated with functional impairments in schizophrenia and moderated by sex, race and symptoms. This has implications for treatment efforts to improve outcomes.

Mentalizing in first-episode psychosis

Mentalizing deficits have often been observed in people with schizophrenia and a few recent studies suggest that such deficits are also present in patients with first episode psychosis (FEP). It is not clear, however, whether these mentalizing deficits in FEP can be accounted for by underlying processes such as social cue recognition, social knowledge and general reasoning. In this study, we assessed mentalizing abilities in 31 people with FEP and 31 matched controls using a novel, comprehensive mentalizing task validated through the present study. We also assessed social cue recognition, social knowledge and non-social (or general) reasoning performance in the same participants in order to determine if the mentalizing deficits in FEP can be at least partly explained by performance in these three underlying processes. Overall, the mentalizing task revealed the greatest impairment in FEP, an impairment that remained significant even after controlling for social cue recognition, social knowledge and non-social reasoning performance. Interestingly, non-social reasoning and social knowledge were both shown to contribute to mentalizing performance. In addition, social cognition measures were linked to social functioning in the FEP group, with the strongest correlation observed with mentalizing performance. Taken together, these results show that mentalizing is an aspect of social cognition that is particularly affected in FEP and might contribute to functional impairments in these patients. These deficits could be a prime target for cognitive remediation in FEP, and our results suggest that this could be done either directly or through improvement of related social and non-social cognitive skills such as social knowledge and general reasoning.

MET and AKT genetic influence on facial emotion perception

BACKGROUND

Facial emotion perception is a major social skill, but its molecular signal pathway remains unclear. The MET/AKT cascade affects neurodevelopment in general populations and face recognition in patients with autism. This study explores the possible role of MET/AKT cascade in facial emotion perception.

METHODS

One hundred and eighty two unrelated healthy volunteers (82 men and 100 women) were recruited. Four single nucleotide polymorphisms (SNP) of MET (rs2237717, rs41735, rs42336, and rs1858830) and AKT rs1130233 were genotyped and tested for their effects on facial emotion perception. Facial emotion perception was assessed by the face task of Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Thorough neurocognitive functions were also assessed.

RESULTS

Regarding MET rs2237717, individuals with the CT genotype performed better in facial emotion perception than those with TT (p = 0.016 by ANOVA, 0.018 by general linear regression model [GLM] to control for age, gender, and education duration), and showed no difference with those with CC. Carriers with the most common MET CGA haplotype (frequency = 50.5%) performed better than non-carriers of CGA in facial emotion perception (p = 0.018, df = 1, F = 5.69, p = 0.009 by GLM). In MET rs2237717/AKT rs1130233 interaction, the C carrier/G carrier group showed better facial emotion perception than those with the TT/AA genotype (p = 0.035 by ANOVA, 0.015 by GLM), even when neurocognitive functions were controlled (p = 0.046 by GLM).

CONCLUSIONS

To our knowledge, this is the first study to suggest that genetic factors can affect performance of facial emotion perception. The findings indicate that MET variances and MET/AKT interaction may affect facial emotion perception, implicating that the MET/AKT cascade plays a significant role in facial emotion perception. Further replication studies are needed.

"Don't give me that look" - overconfidence in false mental state perception in schizophrenia

Dysfunctions in social cognition are implicated in the pathogenesis of schizophrenia and have been extensively replicated over the years. For memory research, the administration of cognitive tasks with metacognitive aspects like confidence ratings has deepened our insight into how impairments contribute to symptoms of the disorder. A total of 76 patients with schizophrenia or schizoaffective disorder and a sample of 30 healthy participants were tested with the Reading the Mind in the Eyes test (Eyes-test). The Eyes-test was complemented with a rating scale requesting response confidence and was administered along with paradigms tapping neuropsychological parameters and cognitive insight. Schizophrenia patients showed impaired abilities on mental state perception. In addition, they committed more high-confidence errors and at the same time made fewer high-confidence correct responses. Impairments were most pronounced in patients with formal thought disorder. The patients displayed a decreased metacognitive awareness for their deficits. The results suggest that adding confidence ratings to the investigation of social cognition promises to advance our understanding of social cognition in schizophrenia. Patients not only show severe impairments in social cognition, but are overconfident in their judgments and lack cognitive insight into their deficits. The results highlight the need for metacognitive therapeutic approaches for the treatment of this population.

The texture of the real: experimentation and experience in schizophrenia

The dominance of the neurosciences in psychiatric research raises questions about the relationship between research practices and the lived experience of mental illness. Here, I use data from a group of researchers focusing on neurocognition in schizophrenia to explore the problem of representation in psychiatric research and the forms that neuroscientific evidence assumes for those who produce it. These researchers grappled with the complexity of schizophrenia not by narrowing disease concepts to biological facts but by referencing measurement techniques to generate new versions of schizophrenia. By linking experimental findings to inchoate concepts of personhood and social experience, I found that they reframed and reinforced cultural values, including that those with schizophrenia are destined to a debased and deficient existence. I argue that cognition has emerged as an essential feature of schizophrenia not only because of its representational utility but also because of the ontological work the concept performs. In closing, I present some implications for the neurobiological and social sciences.

Regulation of negative affect in schizophrenia: the effectiveness of acceptance versus reappraisal and suppression

Although general emotion coping difficulties are well documented in schizophrenia, there has been limited study of specific regulatory strategies such as suppression, reappraisal, and acceptance. In the present study, clinical and control participants were asked to watch video clips selected to elicit negative affect while engaging in one of these three different emotion regulation strategies (counterbalanced), versus a passive viewing condition. The experiential and expressive components of emotion were quantified using self-report and facial electromyography, respectively. A major finding was that, in contrast to control participants, individuals with schizophrenia did not report a greater willingness to reexperience negative emotion after engaging in acceptance. These data are discussed in the context of evidence highlighting the potentially important role of acceptance in understanding affective abnormalities in clinical conditions such as schizophrenia.

Do people with schizophrenia lack emotional intelligence?

Social cognition is a domain of cognitive function that includes the ability to understand and manage social interactions. Emotional intelligence (EI) has been identified as a component of social cognition and is defined as the ability to identify, use, understand, and manage emotions. Neurocognitive impairments are known to be associated with poorer social function in people with schizophrenia, but less is known about the relationships between EI, neurocognition, and social function. The current study assessed EI using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) in 20 people with schizophrenia and 20 controls. The schizophrenia group had significantly lower scores on all measures of EI and demonstrated poorer neurocognition and social functioning than controls. The difference between schizophrenia and control groups was greatest for the Understanding Emotions Branch of the MSCEIT. The neurocognition score and total EI score accounted for 18.3% of the variance in social function in the control group and 9.1% of the variance in social function in the schizophrenia group. Our results suggest that a total EI score is not a useful predictor of overall social function and it may be more clinically useful to develop an individual profile of social cognitive abilities, including EI, to form a remediation program.

The Emotional Intelligence, Health, and Well-Being Nexus: What Have We Learned and What Have We Missed?

This paper reviews the claimed pivotal role of emotional intelligence (EI) in well-being and health. Specifically, we examine the utility of EI in predicting health and well-being and point to future research issues that the field might profitably explore. EI is predictive of various indicators of well-being, as well as both physical and psychological health, but existing research has methodological limitations including over-reliance on self-report measures, and neglect of overlap between EI and personality measures. Interventions focusing on emotional perception, understanding and expression, and emotion regulation, seem potentially important for improving health and well-being, but research on EI has not yet made a major contribution to therapeutic practice. Future research, using a finer-grained approach to measurement of both predictors and criteria might most usefully focus on intra- and inter-personal processes that may mediate effects of EI on health.

Emotional intelligence and clinical symptoms in outpatients with generalized anxiety disorder (GAD)

Generalized anxiety disorder (GAD) is the anxiety disorder with the highest prevalence rate in mental health centers. Empirical researches concerning its diagnosis and treatment have not yet explored the potential implications of deficits in emotional intelligence (EI) as a vulnerability factor in its development. The present study aimed to investigate the relationship between EI and clinical symptoms in a group of psychiatric patients with GAD compared to the control group. Seventy outpatients (82.9% female) with a DSM-IV-TR diagnosis of GAD and 70 control individuals (72.9% female) completed self-report instruments assessing EI and clinical symptoms in a cross-sectional study. Significant correlations were observed between EI dimensions such as clarity (r = .327) and repair (r = .405) and symptoms of anxiety. Also, the dimensions of attention and repair allowed a clear discrimination between clinical patients and control group. The results of the present study showed that deficits in EI abilities were a vulnerability factor in the development of GAD.

Efficacy and specificity of social cognitive skills training for outpatients with psychotic disorders

Psychosocial interventions that target social cognition show promise for enhancing the functional outcomes of people with psychotic disorders. This randomized controlled trial evaluated the efficacy and treatment-outcome specificity of a 24-session Social Cognitive Skills Training (SCST) that targets emotional processing, social perception, attributional bias, and mentalizing (or Theory of Mind). Sixty-eight stable outpatients with primary psychotic disorders were randomly assigned to one of four time- and group format-matched treatment conditions: (1) SCST, (2) computerized neurocognitive remediation, (3) standard illness management skills training, or (4) a Hybrid treatment that combined elements of SCST and neurocognitive remediation. The SCST group demonstrated greater improvements over time than comparison groups in the social cognitive domain of emotional processing, including improvement on measures of facial affect perception and emotion management. There were no differential benefits among treatment conditions on neurocognitive or clinical symptom changes over time. Results indicate that a targeted social cognitive intervention led to improvements in social cognition among outpatients with psychosis. Findings provide guidance for continued efforts to maximize the benefits of social cognitive interventions.

Assessing function and functional outcome in schizophrenia

The diagnosis of schizophrenia can only be made in the presence of a loss of functioning in domains such as employment, independent living, and social functioning. Accurately measuring functioning is central to research on the course of the disorder, treatment and rehabilitation outcomes, and biosocial factors in schizophrenia. Assessments of functional disability have described three dimensions of functioning: functional capacity, functional performance, and functional outcome. The "competence/performance" distinction refers to the observation that an individual may demonstrate an ability to perform a functional task (capacity) but may not do so in her own community environment (performance). Functional outcomes are the result of both capacity and performance. Several recent reviews have compared the characteristics, reliability, and validity of various functional assessment instruments. Two major initiatives are underway to gather additional comparative data about functional assessment strategies. Recently, both the recovery movement and the recognition of the role of environmental factors in functioning have raised questions about the conceptual content of the functioning construct (construct validity). For instance, several studies have demonstrated that features of functioning need not track together over the course of the illness. In addition, the notion of recovery emphasizes processes like community integration and subjective well-being that are not static outcomes but are continually evolving features of the life course in chronic illness. Findings on the dynamic role of environmental moderators such as support and opportunity also present challenges to scientific constructs. For these reasons and others, the ecological validity of functional assessments has become a central concern. Both the verisimilitude and veridicality of functional assessments can be empirically assessed, but to date very few studies have measured the extent to which functional measures accurately predict individuals' behavior in their usual environments. Observational studies in naturalistic environments are one important area for future research.

Selective cocaine-related difficulties in emotional intelligence: relationship to stress and impulse control

Emotional Intelligence (EI) comprises the ability to perceive, use, understand, and regulate emotions and may potentially contribute to variability in risk-related factors such as stress perception and impulse control in cocaine dependent individuals. The main objective of the current study is to better define EI in cocaine dependent individuals compared with healthy controls, using the Mayer, Salovey, and Caruso Emotional Intelligence Test (MSCEIT). Secondary analysis investigates the association between EI, IQ factors, perceived stress, and impulse control in both populations. Seventy-two abstinent treatment-seeking cocaine patients and 52 healthy controls were administered the MSCEIT as well as measures of IQ, perceived stress, and impulse control. Findings showed that cocaine dependent participants demonstrated highly selective EI difficulties compared with healthy controls, specifically with regard to higher-level emotional reasoning including the understanding, management, and regulation of emotion. These EI problems were associated with increased perceived stress and impulse control difficulties. IQ was significantly associated with all MSCEIT measures in the cocaine dependent participants, but not controls. Findings indicate that specific aspects of EI may be of clinical importance to cocaine dependent populations, impacting relapse-related factors such as stress dysregulation and impulse control. 

Decreased self-reported arousal in schizophrenia during aversive picture viewing compared to bipolar disorder and healthy controls

Both schizophrenia (SCZ) and bipolar disorder (BD) are associated with disturbances in emotion processing. Previous studies suggest that patients with SCZ assess unpleasant pictures as less arousing than healthy controls (HC), while patients with BD assess neutral pictures as more arousing than HC. No previous studies have investigated whether there is a difference in emotional response across all three groups. Our aim was to explore whether there was a difference in the evaluation of valence and in arousal between SCZ, BD and HC for aversive and neutral pictures. We showed 72 pictures (neutral, non-socially aversive and socially aversive) from the International Affective Picture System (IAPS) to 347 subjects. There was a clear interaction effect between the diagnostic group and increasing picture aversiveness for both valence and arousal. There were no significant differences in valence ratings between the different groups or in arousal ratings on any type of stimuli between BD patients and HC. However, SCZ patients reported significantly lower arousal for aversive stimuli, particularly with a social content, when compared to BD patients and HC. This was more pronounced in females. The presence of lifetime psychotic symptoms did not influence emotional responses.

The relationship between neurocognition and social cognition with functional outcomes in schizophrenia: a meta-analysis

The current systematic review and meta-analysis provides an extended and comprehensive overview of the associations between neurocognitive and social cognitive functioning and different types of functional outcome. Literature searches were conducted in MEDLINE and PsycINFO and reference lists from identified articles to retrieve relevant studies on cross-sectional associations between neurocognition, social cognition and functional outcome in individuals with non-affective psychosis. Of 285 studies identified, 52 studies comprising 2692 subjects met all inclusion criteria. Pearson correlations between cognition and outcome, demographic data, sample sizes and potential moderator variables were extracted. Forty-eight independent meta-analyses, on associations between 12 a priori identified neurocognitive and social cognitive domains and 4 domains of functional outcome yielded a number of 25 significant mean correlations. Overall, social cognition was more strongly associated with community functioning than neurocognition, with the strongest associations being between theory of mind and functional outcomes. However, as three-quarters of variance in outcome were left unexplained, cognitive remediation approaches need to be combined with therapies targeting other factors impacting on outcome.

Exploring predictors of outcome in the psychosis prodrome: implications for early identification and intervention

Functional disability is a key component of many psychiatric illnesses, particularly schizophrenia. Impairments in social and role functioning are linked to cognitive deficits, a core feature of psychosis. Retrospective analyses demonstrate that substantial functional decline precedes the onset of psychosis. Recent investigations reveal that individuals at clinical-high-risk (CHR) for psychosis show impairments in social relationships, work/school functioning and daily living skills. CHR youth also demonstrate a pattern of impairment across a range of cognitive domains, including social cognition, which is qualitatively similar to that of individuals with schizophrenia. While many studies have sought to elucidate predictors of clinical deterioration, specifically the development of schizophrenia, in such CHR samples, few have investigated factors relevant to psychosocial outcome. This review integrates recent findings regarding cognitive and social-cognitive predictors of outcome in CHR individuals, and proposes potential directions for future research that will contribute to targeted interventions and improved outcome for at-risk youth.
