Emotional intelligence and non-social cognition in schizophrenia and bipolar I disorder

Emotional intelligence: a comparison between patients after first episode mania and those suffering from chronic bipolar disorder type I

BACKGROUND

Deficits in emotional intelligence (EI) were detected in patients with bipolar disorder (BD), but little is known about whether these deficits are already present in patients after presenting a first episode mania (FEM). We sought (i) to compare EI in patients after a FEM, chronic BD and healthy controls (HC); (ii) to examine the effect exerted on EI by socio-demographic, clinical and neurocognitive variables in FEM patients.

METHODS

The Emotional Intelligence Quotient (EIQ) was calculated with the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Performance on MSCEIT was compared among the three groups using generalized linear models. In patients after a FEM, the influence of socio-demographic, clinical and neurocognitive variables on the EIQ was examined using a linear regression model.

RESULTS

In total, 184 subjects were included (FEM n = 48, euthymic chronic BD type I n = 75, HC n = 61). BD patients performed significantly worse than HC on the EIQ [mean difference (MD) = 10.09, standard error (s.e.) = 3.14, p = 0.004] and on the understanding emotions branch (MD = 7.46, s.e. = 2.53, p = 0.010). FEM patients did not differ from HC and BD on other measures of MSCEIT. In patients after a FEM, EIQ was positively associated with female sex (β = -0.293, p = 0.034) and verbal memory performance (β = 0.374, p = 0.008). FEM patients performed worse than HC but better than BD on few neurocognitive domains.

CONCLUSIONS

Patients after a FEM showed preserved EI, while patients in later stages of BD presented lower EIQ, suggesting that impairments in EI might result from the burden of disease and neurocognitive decline, associated with the chronicity of the illness.

Impaired emotional intelligence is related to symptoms severity and suicidal attempts in depression

OBJECTIVE

Few studies demonstrated the impairment of perceived emotional intelligence 'EI' among depressed patients. This study aimed to assess the perceived EI in a group of depressed patients, and its association with different clinical characteristics.

METHODS

Forty-five patients diagnosed with depression were assessed by the Hamilton Depression Rating Scale and compared to 45 controls that were assessed by the Arabic version of General Health Questionnaire to exclude Psychiatric disorders. The Arabic version of Trait Meta-Mood Scale (TMMS) is used to evaluate EI in both groups.

RESULTS

Patients with depression showed significantly lower EI scores in the three parts of TMMS (repair, clarity and attention) compared to the controls (p < .001). Patients showed significant difference in clarity subscale (p = .005) and attention regarding severity of depression (p < .001). Clarity of feelings was significantly higher in patients who suffered more than two episodes (p = .012). Depressive patients with suicidal attempts showed significantly lower scores of repair (p = .044) and attention (p = .016) subscales. There were no significant differences of TMMS subscales between patients with and without suicidal ideation, sleep disturbance and somatic symptoms.

CONCLUSIONS

The current study demonstrates impaired perceived EI among patients with depression that is correlated with symptom severity and suicidal attempts.

The relationship between emotional intelligence and quality of life in schizophrenia and bipolar I disorder

Purpose

Social cognitive skills, both psychosocial functioning and well-being of patients with schizophrenia (SZ) or bipolar disorder (BD), have consistently been shown to be interrelated. While previous research mainly focused on emotion perception, the present study investigates the impact of the other subdomains of emotion processing on a subjective Quality of Life (QoL) estimate and objective QoL indicators. We hypothesized that patients with better performance in the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) report better QoL; and assumed that SZ and BD patients report comparable subjective QoL, whereas BD patients show higher levels of objective QoL.

Methods

Patients diagnosed with either SZ (n = 63) or BD (n = 60), as well as 80 healthy controls, were included into a cross-sectional study. Emotional Intelligence (EI) and QoL were assessed using the MSCEIT and the German version of the Lancashire Quality of Life Profile.

Results

The two patient groups were comparable with regard to overall EI, as well as subjective and objective QoL, but indicated significantly lower levels of EI and QoL than healthy controls. Whereas EI was not associated with both patient groups’ subjective QoL, a significant correlation of EI with objective QoL was only observed in SZ. However, overall effect sizes were small.

Conclusion

Our findings point to a difference in the interrelation between EI and QoL in patients suffering from SZ and BD, and suggest that they may have different needs to achieve recovery. It will be critical to develop training programs targeting EI in SZ, and to examine their impact on objective QoL in these patients.

The social cognitive ability in Han Chinese euthymic patients with bipolar I and bipolar II disorder

BACKGROUND/PURPOSE

Although social cognitive deficits were found in euthymic patients of bipolar disorder (BD), the characteristics of social cognition in Han Chinese euthymic BD patients remain obscure. This study aimed to examine social cognition in Han Chinese euthymic BD patients relative to healthy controls (HC). Moreover, we explore the differences in social cognition between euthymic BD I and BD II patients.

METHODS

43 Han Chinese BD patients (BD-I:25, BD-II:18) and 28 HC were recruited. All patients were euthymic (Young Mania Rating Scale (YMRS) ≤ 7 and Hamilton Depression Rating Scale (HDRS) ≤ 7). Social cognitive ability was measured using Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), including 4 branches: perceiving emotions, facilitating emotions, understanding emotions, and managing emotions. Continuous performance Test (CPT) and Wisconsin Card Sorting Test (WCST) were used to examine attention and executive function.

RESULTS

Significant difference in understanding emotions branch of MSCEIT was found between BD patients and HCs (Mann-Whitney U test, p = 0.005). Besides, BD patients had significantly worse performance in WCST and CPT. However, the differences in WCST, CPT, MSCEIT total scores and its subscales were not significant between BD I and BD II patients.

CONCLUSION

Euthymic Han Chinese BD patients exhibit significant social cognitive deficits in understanding emotion and cognitive dysfunction in attention and executive function. Furthermore, Han Chinese BD I patients showed similar social cognitive and general cognitive ability as compared with BD II patients. Social cognitive rehabilitation on both euthymic BD I and II patients should be considered.

Neurocognitive functioning during symptomatic states and remission in bipolar disorder and schizophrenia: A comparative study

Aims Patients with bipolar disorder present milder cognitive impairment in comparison to patients with schizophrenia. Psychotic symptoms are associated with poorer cognitive functioning in both disorders. We aim to compare cognitive dysfunction between bipolar disorder and schizophrenia across symptomatic and remitted states. Methods An extensive cognitive battery was used to assess bipolar disorder patients (32 in manic episodes with psychotic features, 44 in euthymia), patients with schizophrenia (41 symptomatic, 39 remitted), and 55 healthy controls. A global cognitive factor and six neurocognitive domain factors were identified using principal component analyses. Results Global cognition components differed according to both illness and remission status; working memory differed according to remission status regardless of diagnosis; verbal fluency differed according to diagnosis regardless of remission status. An omnibus F test revealed that the remission state had a significant impact on processing speed in schizophrenia. Conclusion Our data suggest that both disorders are associated with state dependent (i.e., global cognition and working memory) and diagnosis dependent (i.e., global cognition and verbal fluency) neurocognitive dysfunctions. Processing speed was exclusively influenced by symptomatic states of schizophrenia.

Emotional intelligence in bipolar-I-disorder: A comparison between patients, unaffected siblings, and control subjects

BACKGROUND

Impairments in social and nonsocial cognition have been demonstrated in both patients suffering from bipolar disorder (BD) and their unaffected relatives and might therefore represent a heritable marker of risk. This study investigated the relevance of emotional intelligence (EI) as part of the emotion processing domain of social cognition in this regard.

METHODS

A total of 54 outpatients suffering from BD, 54 unaffected siblings, and 80 control subjects were investigated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Brief Assessment of Cognition in Schizophrenia (BACS). Analyses of covariance (ANCOVAs) were performed with adjustment for the BACS composite score. The three groups were compared by one-way analysis of variance or chi-square test, depending on the variable type. As the three groups differed significantly in their level of education, additional ANCOVAs with adjustment for education were performed.

RESULTS

Patients achieved significantly lower levels of overall EI and overall nonsocial cognitive functioning compared to unaffected siblings and controls, whereas performance of the latter two groups was comparable in both domains.

CONCLUSIONS

Due to comparable levels of EI in unaffected siblings of patients suffering from BD and control subjects, EI assessed by means of the MSCEIT does not represent an endophenotype for BD.

Cerebellar-Cortical Connectivity Is Linked to Social Cognition Trans-Diagnostically

Background: Psychotic disorders are characterized by impairment in social cognitive processing, which is associated with poorer community functioning. However, the neural mechanisms of social impairment in psychosis remain unclear. Social impairment is a hallmark of other psychiatric illnesses as well, including autism spectrum disorders (ASD), and the nature and degree of social cognitive impairments across psychotic disorders and ASD are similar, suggesting that mechanisms that are known to underpin social impairments in ASD may also play a role in the impairments seen in psychosis. Specifically, in both humans and animal models of ASD, a cerebellar-parietal network has been identified that is directly related to social cognition and social functioning. In this study we examined social cognition and resting-state brain connectivity in people with psychosis and in neurotypical adults. We hypothesized that social cognition would be most strongly associated with cerebellar-parietal connectivity, even when using a whole-brain data driven approach. Methods: We examined associations between brain connectivity and social cognition in a trans-diagnostic sample of people with psychosis (n = 81) and neurotypical controls (n = 45). Social cognition was assessed using the social cognition domain score of the MATRICS Consensus Cognitive Battery. We used a multivariate pattern analysis to correlate social cognition with resting-state functional connectivity at the individual voxel level. Results: This approach identified a circuit between right cerebellar Crus I, II and left parietal cortex as the strongest correlate of social cognitive performance. This connectivity-cognition result was observed in both people with psychotic disorders and in neurotypical adults. Conclusions: Using a data-driven whole brain approach we identified a cerebellar-parietal circuit that was robustly associated with social cognitive ability, consistent with findings from people with ASD and animal models. These findings suggest that this circuit may be marker of social cognitive impairment trans-diagnostically and support cerebellar-parietal connectivity as a potential therapeutic target for enhancing social cognition.

Affective cognition in bipolar disorder: A systematic review by the ISBD targeting cognition task force

BACKGROUND

Impairments in affective cognition are part of the neurocognitive profile and possible treatment targets in bipolar disorder (BD), but the findings are heterogeneous. The International Society of Bipolar Disorder (ISBD) Targeting Cognition Task Force conducted a systematic review to (i) identify the most consistent findings in affective cognition in BD, and (ii) provide suggestions for affective cognitive domains for future study and meta-analyses.

METHODS

The review included original studies reporting behavioral measures of affective cognition in BD patients vs controls following the procedures of the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) statement. Searches were conducted on PubMed/MEDLINE, EMBASE, and PsychInfo from inception until November 2018.

RESULTS

A total of 106 articles were included (of which nine included data for several affective domains); 41 studies assessed emotional face processing; 23 studies investigated reactivity to emotional words and images; 3 investigated explicit emotion regulation; 17 assessed implicit emotion regulation; 31 assessed reward processing and affective decision making. In general, findings were inconsistent. The most consistent findings were trait-related difficulties in facial emotion recognition and implicit emotion regulation, and impairments in reward processing and affective decision making during mood episodes. Studies using eye-tracking and facial emotion analysis revealed subtle trait-related abnormalities in emotional reactivity.

CONCLUSION

The ISBD Task Force recommends facial expression recognition, implicit emotion regulation, and reward processing as domains for future research and meta-analyses. An important step to aid comparability between studies in the field would be to reach consensus on an affective cognition test battery for BD.

Social cognition in bipolar disorder: the role of sociodemographic, clinical, and neurocognitive variables in emotional intelligence

OBJECTIVE

The main aims of this study were to examine the differences in the Emotional Intelligence (EI), the emotional domain of social cognition (SC), between euthymic patients with bipolar disorder (BD) and healthy controls (HC) and to evaluate the contribution of sociodemographic, clinical, and neuropsychological variables to EI.

METHODS

We recruited 202 patients with BD and 50 HC. EI was evaluated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). The sociodemographic, clinical, and neurocognitive variables that showed a significant association with EI were entered into hierarchical multiple regression analysis.

RESULTS

BD patients obtained significantly lower scores compared to HC in the Emotional Intelligence Quotient (EIQ) and in the Understanding Emotions branch score. The best fitting model for the variables associated with EI in the patients group was a linear combination of gender, estimated IQ, family history of affective diagnosis, and executive function. The model, including these previous variables, explained up to 27.6% of the observed variance (R²  = 0.276, F = 16.406, P < 0.001).

CONCLUSIONS

The identification of variables associated with deficit in EI, such as male gender, lower estimated IQ, family history of affective diagnosis. and lower executive function performance, may help in selecting treatment targets to improve SC, and especially EI, in patients with BD.

Emotional intelligence and schizophrenia spectrum disorders: a critical review

Abstract Introduction Emotional intelligence (EI) is a theoretical construct postulated by Mayer and Salovey to designate the ability to perceive, understand, use and manage emotions. The study of EI in schizophrenia offers new insights into the disorder’s cognitive and functional impacts. Objectives To comprehensively review studies analyzing EI impairment in schizophrenia spectrum disorders using standardized instruments. Methods Searches were run on MEDLINE/PubMed, Google Scholar, Cochrane, LILACS, Embase, ClinicalTrials.gov and SciELO databases. The only validated instrument used was the Multifactor Emotional Intelligence Scale (MSCEIT). Articles that used all branches of the MSCEIT to assess EI in schizophrenia spectrum disorders and healthy controls were included in the review. Results We found 30 articles on this topic. The studies analyzed showed a significant impairment of MSCEIT total score in patients with schizophrenia spectrum disorders when compared to healthy controls. In relation to the MSCEIT branches, understanding of emotions and management of emotions are the most impaired branches. Conclusion Since most studies are cross-sectional, it is not possible to establish a cause and effect relationship between EI deficits and schizophrenia spectrum disorders. Therefore, longitudinal studies are needed to establish a clearer relationship between these variables. By so doing, we may be able to intervene for prevention and management of these disorders, aiming at better quality of life for patients.

Combined Processing of Facial and Vocal Emotion in Remitted Patients With Bipolar I Disorder

OBJECTIVES

Bipolar disorder (BD) is associated with impairments in facial emotion and emotional prosody perception during both mood episodes and periods of remission. To expand on previous research, the current study investigated cross-modal emotion perception, that is, matching of facial emotion and emotional prosody in remitted BD patients.

METHODS

Fifty-nine outpatients with BD and 45 healthy volunteers were included into a cross-sectional study. Cross-modal emotion perception was investigated by using two subtests out of the Comprehensive Affective Testing System (CATS).

RESULTS

Compared to control subjects patients were impaired in matching sad (p &lt; .001) and angry emotional prosody (p = .034) to one of five emotional faces exhibiting the corresponding emotion and significantly more frequently matched sad emotional prosody to happy faces (p &lt; .001) and angry emotional prosody to neutral faces (p = .017). In addition, patients were impaired in matching neutral emotional faces to the emotional prosody of one of three sentences (p = .006) and significantly more often matched neutral faces to sad emotional prosody (p = .014).

CONCLUSIONS

These findings demonstrate that, even during periods of symptomatic remission, patients suffering from BD are impaired in matching facial emotion and emotional prosody. As this type of emotion processing is relevant in everyday life, our results point to the necessity to provide specific training programs to improve psychosocial outcomes. (JINS, 2019, 25, 336-342).

Association between cognitive deficits and suicidal ideation in patients with major depressive disorder

The role of cognitive function in suicidal ideation in patients with major depressive disorder (MDD) has not been adequately explored. This research sought to measure the relationship between suicidal ideation and cognitive function. Therefore, in this study, the association between cognitive function and suicidal ideation in patients with MDD was assessed. Cognitive function was evaluated in 233 patients with MDD using the Japanese version of the Brief Assessment of Cognition in Schizophrenia (BACS). Suicidal ideation was assessed using item 3 of the Hamilton Depression Rating Scale. Approximately 59.2% of the patients (138/233) expressed suicidal ideation. Among the BACS subtests, only the executive function scores were significantly lower in patients with MDD with than in those without (p < 0.005). In addition, the executive function, motor speed function, and composite scores correlated negatively with the severity of suicidal ideation in these patients. These results suggest that executive function, motor speed function, and global neuropsychological function are associated with suicidal ideation in patients with MDD and that the BACS neuropsychological battery is an efficient instrument for monitoring these characteristics. Moreover, specific BACS scores can potentially serve as cognitive biomarkers of suicide risk in patients with MDD.

Is Emotional Intelligence Impaired in Unaffected Siblings of Patients with Schizophrenia?

OBJECTIVES

Social cognitive deficits have been discussed to be endophenotypes for schizophrenia and other serious mental illnesses. The current study aimed to assess emotional intelligence (EI) in unaffected siblings of schizophrenia patients to investigate its potential role as endophenotype for schizophrenia.

METHODS

EI was measured in 56 schizophrenia patients, 57 unaffected siblings, and 127 healthy control subjects by using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). In addition, non-social cognition was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Linear mixed models with compound symmetric correlation structure were used for of the three groups with respect to EI and non-social cognition.

RESULTS

Schizophrenia patients showed significantly lower overall EI and performed significantly worse in three out of four MSCEIT branches compared to unaffected siblings and control subjects, whereas the two latter groups had comparable EI levels. Similar performance patterns (patients<unaffected siblings=control subjects) were found with respect to non-social cognition. Solely in the "Tower of London" test, siblings achieved significantly lower task scores compared to control subjects.

CONCLUSIONS

Based on our results, EI as measured with the MSCEIT does not seem to represent a marker of risk for schizophrenia. Further investigations should concentrate on other EI measures to reassess this finding. (JINS, 2017, 23, 577-583).

Social cognition in bipolar disorder: Focus on emotional intelligence

BACKGROUND

The present study aims to characterize emotional intelligence (EI) variability in a sample of euthymic bipolar disorder (BD) patients through the Mayer- Salovey-Caruso Emotional Intelligence Test (MSCEIT).

METHOD

A total of 134 euthymic BD outpatients were recruited and divided into three groups according to the total Emotional Intelligence Quotient (EIQ) score of the MSCEIT, following a statistical criterion of scores 1.5SDs above/below the normative group mean, as follows: a low performance (LP) group (EIQ <85), a normal performance (NP) group (85≤EIQ≤115), and a high performance (HP) group (EIQ >115). Afterwards, main sociodemographic, clinical, functional and neurocognitive variables were compared between the groups.

RESULTS

Three groups were identified: 1) LP group (n=16, 12%), 2) NP group (n=93, 69%) and 3) HP group (n=25, 19%). There were significant differences between the groups in premorbid intelligence quotient (IQ) (p=0.010), axis II comorbidity (p=0.008), subthreshold depressive symptoms (p=0.027), general functioning (p=0.013) and in four specific functional domains: autonomy, occupation, interpersonal relations and leisure time. Significant differences in neurocognitive performance were found between groups with the LP group showing the lowest attainments.

LIMITATIONS

The cross-sectional design of the study.

CONCLUSION

Our results suggest that EI variability among BD patients, assessed through MSCEIT, is lower than expected. EI could be associated with premorbid IQ, subthreshold depressive symptoms, neurocognitive performance and general functioning. The identification of different profiles of SC may help guide specific interventions for distinct patient subgroups aimed at improving social cognition, neurocognitive performance and psychosocial functioning.

Ability-based emotional intelligence in schizophrenia

PURPOSE OF REVIEW

As one part of social cognition, emotional intelligence is a controversially discussed construct. Although well founded critique on the conceptualization of emotional intelligence has emerged over the last years, studies about emotional intelligence - especially the ability-based approach by Mayer and Salovey - can persistently be found in schizophrenia research.

RECENT FINDINGS

Studies published between October 2015 and October 2016 were included in this review. The majority of the studies addressed the associations between ability-based emotional intelligence and other clinical or neuropsychological features, for example symptom severity or executive functioning. One study investigated the effect of oxytocin on emotional intelligence and another dealt with the question, whether emotional intelligence could be an endophenotype for schizophrenia.

SUMMARY

The reviewed literature reveals that patients with schizophrenia exhibit impairments in ability-based emotional intelligence. In this context, non-social cognition, positive symptoms, and anomalous-self experiences seem to be of major relevance. The potential endophenotypic role of ability-based emotional intelligence in schizophrenia remains to be clarified.
