Differences in emotion processing in patients with essential and secondary hypertension

Emotional awareness for self and others and empathic abilities in clinical depression during acute illness and recovery

BACKGROUND

The present longitudinal investigation had two major goals. First, we intended to clarify whether depressed patients are characterized by impairments of emotional awareness for the self and the other during acute illness and whether these impairments diminish in the course of an inpatient psychiatric treatment program. Previous research based on the performance measure Levels of Emotional Awareness Scale (LEAS) provided inconsistent findings concerning emotional self-awareness in clinical depression. Second, we investigated whether cognitive and affective empathic abilities change from acute illness to recovery in depressed patients.

METHODS

Fifty-eight depressed patients were tested on admission and after 6-8 weeks of inpatient psychiatric treatment. A sample of fifty-three healthy individuals were also examined twice at an interval of 6-8 weeks. The LEAS and the Interpersonal Reactivity Index (IRI) were administered to assess emotional awareness and empathic abilities. Written texts were digitalized and then analyzed using the electronic scoring program geLEAS, the German electronic Levels of Emotional Awareness Scale.

RESULTS

Depressed patients reported more depressive symptoms than healthy controls and less severe depressive symptomatology at time 2 compared to time 1. Independent of time, depressed individuals tended to show lower geLEAS self scores and had lower geLEAS other scores than healthy individuals. Depressed patients showed higher personal distress scores than healthy individuals at both measurement times. No group differences were observed for the cognitive empathy scales of the IRI (perspective taking and fantasy) and empathic concern, but empathic concern decreased significantly in depressed patients from time 1 to time 2. Empathic abilities as assessed by the IRI were not significantly correlated with emotional awareness for others, neither in the whole sample, nor in the patient and control subsample.

CONCLUSIONS

Depressed patients seem to be characterized by impairments in emotional awareness of others during acute illness and recovery, but they also tend to show deficits in emotional self-awareness compared to healthy individuals. Self-reported cognitive empathic abilities seem to be at normal levels in depressed patients, but their heightened self-focused affective empathy may represent a vulnerability factor for depressive disorders.

Aminopeptidase Activities Interact Asymmetrically between Brain, Plasma and Systolic Blood Pressure in Hypertensive Rats Unilaterally Depleted of Dopamine

Brain dopamine, in relation to the limbic system, is involved in cognition and emotion. These functions are asymmetrically processed. Hypertension not only alters such functions but also their asymmetric brain pattern as well as their bilateral pattern of neurovisceral integration. The central and peripheral renin-angiotensin systems, particularly the aminopeptidases involved in its enzymatic cascade, play an important role in blood pressure control. In the present study, we report how these aminopeptidases from left and right cortico-limbic locations, plasma and systolic blood pressure interact among them in spontaneously hypertensive rats (SHR) unilaterally depleted of dopamine. The study comprises left and right sham and left and right lesioned (dopamine-depleted) rats as research groups. Results revealed important differences in the bilateral behavior comparing sham left versus sham right, lesioned left versus lesioned right, and sham versus lesioned animals. Results also suggest an important role for the asymmetrical functioning of the amygdala in cardiovascular control and an asymmetrical behavior in the interaction between the medial prefrontal cortex, hippocampus and amygdala with plasma, depending on the left or right depletion of dopamine. Compared with previous results of a similar study in Wistar-Kyoto (WKY) normotensive rats, the asymmetrical behaviors differ significantly between both WKY and SHR strains.

Levels of Emotional Awareness: Theory and Measurement of a Socio-Emotional Skill

Emotional awareness is the ability to conceptualize and describe one's own emotions and those of others. Over thirty years ago, a cognitive-developmental theory of emotional awareness patterned after Piaget's theory of cognitive development was created as well as a performance measure of this ability called the Levels of Emotional Awareness Scale (LEAS). Since then, a large number of studies have been completed in healthy volunteers and clinical populations including those with mental health or systemic medical disorders. Along the way, there have also been further refinements and adaptations of the LEAS such as the creation of a digital version in addition to further advances in the theory itself. This review aims to provide a comprehensive summary of the evolving theoretical background, measurement methods, and empirical findings with the LEAS. The LEAS is a reliable and valid measure of emotional awareness. Evidence suggests that emotional awareness facilitates better emotion self-regulation, better ability to navigate complex social situations and enjoy relationships, and better physical and mental health. This is a relatively new but promising area of research in the domain of socio-emotional skills. The paper concludes with some recommendations for future research.

Affective agnosia: a core affective processing deficit in the alexithymia spectrum

Affective agnosia, an impairment in knowing how one feels emotionally, has been described as an extreme deficit in the experience and expression of emotion that may confer heightened risk for adverse medical outcomes. Alexithymia, by contrast, has been proposed as an over-arching construct that includes a spectrum of deficits of varying severity, including affective agnosia at the more severe end. This perspective has been challenged by Taylor and colleagues, who argue that the concept of affective agnosia is unnecessary. We compare these two perspectives by highlighting areas of agreement, reasons for asserting the importance of the affective agnosia concept, errors in Taylor and colleagues’ critique, and measurement issues. The need for performance-based measures of the ability to mentally represent emotional states in addition to metacognitive measures is emphasized. We then draw on a previously proposed three-process model of emotional awareness that distinguishes affective response generation, conceptualization and cognitive control processes which interact to produce a variety of emotional awareness and alexithymia phenotypes - including affective agnosia. The tools for measuring these three processes, their neural substrates, the mechanisms of brain-body interactions that confer heightened risk for adverse medical outcomes, and the differential treatment implications for different kinds of deficits are described. By conceptualizing alexithymia as a spectrum of deficits, the opportunity to match specific deficit mechanisms with personalized treatment for patients will be enhanced.

Multicentric evidence of emotional impairments in hypertensive heart disease

The mechanisms underlying emotional alterations constitute a key research target in neuroscience. Emerging evidence indicates that these disruptions can be related to abnormal interoception (i.e., the sensing of visceral feelings), as observed in patients with cardiodynamic deficits. To directly assess these links, we performed the first multicenter study on emotion recognition and interoception in patients with hypertensive heart disease (HHD). Participants from two countries completed a facial emotion recognition test, and a subsample additionally underwent an interoception protocol based on a validated heartbeat detection task. HHD patients from both countries presented deficits in the recognition of overall and negative emotions. Moreover, interoceptive performance was impaired in the HHD group. In addition, a significant association between interoceptive performance and emotion recognition was observed in the control group, but this relation was abolished in the HHD group. All results survived after covariance with cognitive status measures, suggesting they were not biased by general cognitive deficits in the patients. Taken together, these findings suggest that emotional recognition alterations could represent a sui generis deficit in HHD, and that it may be partially explained by the disruption of mechanisms subserving the integration of neuro-visceral signals.

Allostatic overload in patients with essential hypertension

The role of psychosocial stress in the development of essential hypertension has attracted increasing attention in the last decades, even though research findings have been often inconclusive. We specifically investigated allostatic overload (AO) in hypertensive patients using a clinimetric approach. Allostatic overload was assessed by a semi-structured research interview based on clinimetric criteria in 80 consecutive outpatients with essential hypertension (46.3 % females; mean age 62.18 ± 8.59 years; age range 47-74 years) and 80 normotensive matched controls. Three clinical interviews and two self-rating questionnaires for assessing psychological distress and well-being were also administered. Cardiac variables were collected. AO was present in 26 (32.5 %) of the hypertensive patients based on clinical interviewing, and in only 6 normotensive controls (p < .001). Hypertensive patients with AO had significantly higher levels of psychological distress than those without. Further, patients with AO displayed significantly lower levels of well-being and quality of life (p < .001). A significantly greater prevalence of psychosomatic syndromes was found to be associated with the presence of AO (p < .05), whereas no significant association was detected as to psychiatric diagnoses. Significantly greater cardiovascular risk was found among hypertensive patients reporting AO compared to those without (p < .05). The results of this study support the clinical relevance of a psychological assessment of hypertensive patients, with important implications for the non-pharmacological management of hypertension.

Simulating Emotions: An Active Inference Model of Emotional State Inference and Emotion Concept Learning

The ability to conceptualize and understand one's own affective states and responses - or "Emotional awareness" (EA) - is reduced in multiple psychiatric populations; it is also positively correlated with a range of adaptive cognitive and emotional traits. While a growing body of work has investigated the neurocognitive basis of EA, the neurocomputational processes underlying this ability have received limited attention. Here, we present a formal Active Inference (AI) model of emotion conceptualization that can simulate the neurocomputational (Bayesian) processes associated with learning about emotion concepts and inferring the emotions one is feeling in a given moment. We validate the model and inherent constructs by showing (i) it can successfully acquire a repertoire of emotion concepts in its "childhood", as well as (ii) acquire new emotion concepts in synthetic "adulthood," and (iii) that these learning processes depend on early experiences, environmental stability, and habitual patterns of selective attention. These results offer a proof of principle that cognitive-emotional processes can be modeled formally, and highlight the potential for both theoretical and empirical extensions of this line of research on emotion and emotional disorders.

Higher Emotional Awareness Is Associated With Reduced Pain in Irritable Bowel Syndrome Patients: Preliminary Results

OBJECTIVE

Recent evidence indicates that interventions designed to improve emotional awareness reduce pain in irritable bowel syndrome. This preliminary study sought to determine whether trait emotional awareness is associated with typical pain in patients with irritable bowel syndrome.

METHODS

Healthy volunteers (n = 66) and irritable bowel syndrome patients (n = 50) were asked to self-report their typical levels of pain intensity and complete both the Levels of Emotional Awareness Scale and the Somatization Scale of the Brief Symptom Inventory.

RESULTS

Levels of Emotional Awareness Scale scores in irritable bowel syndrome patients did not differ from scores in healthy participants; however, higher Levels of Emotional Awareness Scale scores in irritable bowel syndrome patients predicted lower levels of typical pain intensity (r(45) = -.36, p = .01, 95% CI [-.59, -.08]) and lower levels of somatization (r(45)= -.31, p = .03, 95% CI [-.55, -.02]).

CONCLUSIONS

This inverse relationship between emotional awareness and both pain and somatization symptoms is consistent with evidence that irritable bowel syndrome patients experience reduced pain from therapies designed to improve emotional awareness. The Levels of Emotional Awareness Scale could potentially be used to identify patients who could benefit from such therapy and could potentially be a moderator of response to efficacious psychological therapies.

Higher levels of trait emotional awareness are associated with more efficient global information integration throughout the brain: a graph-theoretic analysis of resting state functional connectivity

Previous studies have suggested that trait differences in emotional awareness (tEA) are clinically relevant, and associated with differences in neural structure/function. While multiple leading theories suggest that conscious awareness requires widespread information integration across the brain, no study has yet tested the hypothesis that higher tEA corresponds to more efficient brain-wide information exchange. Twenty-six healthy volunteers (13 females) underwent a resting state functional magnetic resonance imaging scan, and completed the Levels of Emotional Awareness Scale (LEAS; a measure of tEA) and the Wechsler Abbreviated Scale of Intelligence (WASI-II; a measure of general intelligence quotient [IQ]). Using a whole-brain (functionally defined) region of interest (ROI) atlas, we computed several graph theory metrics to assess the efficiency of brain-wide information exchange. After statistically controlling for differences in age, gender and IQ, we first observed a significant relationship between higher LEAS scores and greater average degree (i.e. overall whole-brain network density). When controlling for average degree, we found that higher LEAS scores were also associated with shorter average path lengths across the collective network of all included ROIs. These results jointly suggest that individuals with higher tEA display more efficient global information exchange throughout the brain. This is consistent with the idea that conscious awareness requires global accessibility of represented information.

Emotional Processing In Patients with Ischemic Heart Diseases

BACKGROUND:

Cardiovascular disease is the most prevalent public health problem on a worldwide scale, and ischemic heart disease accounts for approximately one-half of these events in high-income countries. One of the most important risk factors for this disease is mental and psychological especially stressful experiences.

AIM:

This research was established to compare emotional processing, as a key factor in stress appraisal, between IHD patients and people with no cardiovascular disease.

METHODS:

Using simple sampling, fifty patients were selected from people who diagnosed as IHD in the hospital and referred for treatment after discharging care and treatment. Control group participants were selected as control group peoples, using neighbourhood controls selection. The Emotional Processing Scale was filled by all members of the two groups.

RESULTS:

There were significant differences between the two groups on the EPS-25 total scores, as well as on emotional processing dimensions of signs of unprocessed emotion, unregulated emotion; avoidance and impoverished. Also, there was no significant difference between the two groups in the dimension of Suppression. The final step of regression revealed a β of 10.15 and 1.05 for AVO and IEE subscales respectively.

CONCLUSION:

The result showed that patients with IHD are using more negative emotional processing styles.

Common and Unique Neural Systems Underlying the Working Memory Maintenance of Emotional vs. Bodily Reactions to Affective Stimuli: The Moderating Role of Trait Emotional Awareness

Many leading theories suggest that the neural processes underlying the experience of one's own emotional reactions partially overlap with those underlying bodily perception (i.e., interoception, somatosensation, and proprioception). However, the goal-directed maintenance of one's own emotions in working memory (EWM) has not yet been compared to WM maintenance of one's own bodily reactions (BWM). In this study, we contrasted WM maintenance of emotional vs. bodily reactions to affective stimuli in 26 healthy individuals while they underwent functional magnetic resonance imaging. Specifically, we examined the a priori hypothesis that individual differences in trait emotional awareness (tEA) would lead to greater differences between these two WM conditions within medial prefrontal cortex (MPFC). We observed that MPFC activation during EWM (relative to BWM) was positively associated with tEA. Whole-brain analyses otherwise suggested considerable similarity in the neural activation patterns associated with EWM and BWM. In conjunction with previous literature, our findings not only support a central role of body state representation/maintenance in EWM, but also suggest greater engagement of MPFC-mediated conceptualization processes during EWM in those with higher tEA.

[Psychosomatic research in 2018: Lost illusions, renewed hopes]

A critical analysis of the basic hypotheses of psychosomatic research and the sometimes hasty assertions drawn from the previous works makes it possible to better discern the data confirmed by the most recent works or the most rigorous meta-analyses and to highlight the emerging tracks. If the hypothesis of behavioral patterns specifically related to the risk of certain pathologies seems abandoned, the predictive value of depression in the cardiovascular field, more than in that of oncology, becomes clearer. Negative affect and impaired emotional awareness emerge as two complementary factors of somatic vulnerability. Several vulnerability factors seem all the more effective as they affect individuals of lower socio-economic status. Social exclusion feeling and its links with the inflammatory response appear to be a possible common denominator, both for depression and for many somatic conditions. A series of studies on the cerebral regulation of emotions and stress, as well as on bidirectional brain-bowel relations and on the mediating role of the gut microbiota, complements the available epidemiological data. The same is true for certain advances in behavioral neuro-economics, which inform the decision-making processes of patients facing preventive health choices. Lastly, it appears that a significant part of the excess mortality associated with the existence of severe mental disorders is not due to factors inherent to the patients themselves, but to disparities in the quality of the care provided to them.

Dimensions of Body-Awareness and Depressed Mood and Anxiety

Interoception, the multidimensional ability to sense the physiological condition of the body, is a key mechanism in emotional processing. However, the relationships between interoceptive dimensions and depressed mood and anxiety have not been widely studied. The aim of this secondary analysis, correlational and cross-sectional study, was to determine the relationships among interoceptive accuracy, interoceptive sensibility, depressed mood, and anxiety in adults with hypertension. The sample consisted of 76 adults, predominately African American women. Correlational analysis showed that most participants had low levels of interoceptive accuracy and relatively high levels of interoceptive sensibility. Interoceptive sensibility was negatively associated with depressed mood and anxiety. Interoceptive accuracy and interoceptive sensibility were not associated between each other. Further examination of the dimensions of interoception is needed to better understand the mechanisms by which it is associated with emotions that are known to have an influence on health behaviors and quality of life.

Association Between Alexithymia and Risk of Incident Cardiovascular Diseases in the SUpplémentation en VItamines et Minéraux AntioXydants (SU.VI.MAX) Cohort

OBJECTIVE

Although it has been suggested that alexythymia is associated with cardiovascular diseases, studies are scarce and a causal relationship is questionable. This study explored the prospective association between alexithymia and cardiovascular events in middle-aged participants without cardiovascular history at baseline.

METHODS

The 26-item Toronto Alexithymia Scale (TAS-26) was completed by 5586 participants of the French SUpplémentation en VItamines et Minéraux AntioXydants cohort (41.4% of men, M [SD] age = 52.2 [6.3] years) in 1996-1997. Covariates measured at baseline included age, occupational status, depressive symptoms, smoking status, body mass index, hypertension, diabetes, hypercholesterolemia, and hypertriglyceridemia. The follow-up ran from January 1, 1998, to the date of the first cardiovascular event, the date of death or September 1, 2007, whichever occurred first. Cardiovascular events were validated by an independent expert committee. Hazard ratios and 95% confidence intervals were computed with Cox regressions.

RESULTS

During an average of 8.9 years of follow-up, 171 first cardiovascular events were validated. After adjustment for age, sex, and occupational status, there was no association between baseline alexithymia and cardiovascular events at follow-up (hazard ratio [95% confidence interval] for 15 points of TAS-26 = 1.00 [0.81-1.23], p > .99). Adjusting for all covariates, using binary TAS-26 cut-offs or TAS-26 subscores yielded similar nonsignificant results.

CONCLUSIONS

In this large prospective study, alexithymia and cardiovascular events were not associated among a nonclinical population. This casts some doubt on whether alexithymia could be a meaningful target in the prevention of cardiovascular diseases.

The impact of attachment distress on affect-centered mentalization: An experimental study in psychosomatic patients and healthy adults

Introduction

We investigated the impact of attachment distress on affect-centered mentalization in a clinical and a non-clinical sample, comparing mentalization in a baseline condition to mentalization under a condition of attachment distress.

Methods

The sample consisted of 127 adults who underwent inpatient psychosomatic treatment, and 34 mentally healthy adults. Affect-centered mentalization was assessed by analyzing participants’ narratives on interpersonal situations in a baseline condition with the Levels of Emotional Awareness Scale (LEAS), and an experimental condition inducing attachment distress with the Adult Attachment Projective Picture System (AAP). Unlike the LEAS, the AAP is specifically designed to trigger attachment distress. In both conditions, the narratives were evaluated using the LEAS scoring system. Additionally, we assessed the impact of childhood trauma on affect-centered mentalization with the Childhood Trauma Questionnaire (CTQ).

Results

While the non-clinical sample displayed the same level of affect-centered mentalization in both conditions, the majority of the clinical sample reached higher scores in the attachment distress condition. There was no strong relationship between reported trauma and mentalization scores.

Discussion

Our findings lend strong empirical support to the assumption that affect-centered mentalization is modulated by attachment-related distress. Several possible explanations for the differences between and within the clinical and the non-clinical sample are discussed.

The Relationship Between Alexithymia and Emotional Awareness: A Meta-Analytic Review of the Correlation Between TAS-20 and LEAS

Background: Alexithymia and emotional awareness may be considered overlapping constructs and both have been shown to be related to psychological and emotional well-being. However, it is not clear how the constructs relate to each other empirically or if they may overlap more or less in different populations. The aim of this review was therefore to conduct a meta-analysis of correlations between the most commonly used measures of alexithymia (i.e., the self-report instrument Toronto Alexithymia Scale; TAS-20) and emotional awareness (i.e., the observer-rated instrument Level of Emotional Awareness Scale; LEAS) and to explore potential moderators of their relationship.

Methods: Electronic databases were searched for studies published until the end of February 2018. Study samples were coded as medical conditions, psychiatric disorders and/or healthy controls and sample mean age and gender distribution were extracted. Correlations between the TAS-20 and the LEAS were subjected to a random effect of meta-analysis and moderators were explored in subgroup analyses and meta-regressions. Publication bias was considered.

Results: 21 studies reporting on 28 independent samples on correlation analysis were included, encompassing a total of 2857 subjects (57% women). The aggregated correlation between TAS-20 and LEAS was r = −0.122 (95% CI [−0.180, −0.064]; Z = −4.092; p < 0.001), indicating a significant, but weak, negative relationship between the measures. Heterogeneity was moderate, but we found no indication of significant differences between patients with medical conditions, psychiatric disorders or healthy controls, nor that mean age or percentage of female subjects moderated the relationship. The overall estimate became somewhat weaker after adjusting for possible publication bias.

Conclusions: Our results indicate that TAS-20 and LEAS measure different aspects of emotional functioning. The small overlap suggests that alexithymia and emotional awareness are distinct constructs of emotional well-being. Clinicians need to assess both aspects when considering treatment options for individual patients. Moreover, from the clinical standpoint, an easy reliable and valid way of measuring emotional awareness is still needed. More research should be focus on the differences between alexithymia and emotional awareness in specific conditions, but also how to integrate self-report instrument and observed based measures in a clinical situation.

Poor emotional responsiveness in clinical hypertension: Reduced accuracy in the labelling and matching of emotional faces amongst individuals with hypertension and prehypertension

Psychological factors are known to play an important part in the origin of many medical conditions including hypertension. Recent studies have reported elevated blood pressure (even in the normal range of variation) to be associated with a reduced responsiveness to emotions or 'emotional dampening'. Our aim was to assess emotional dampening in individuals with more extreme blood pressure levels including prehypertensives (N = 58) and hypertensives (N = 60) by comparing their emotion recognition ability with normotensives (N = 57). Participants completed novel facial emotion matching and facial emotion labelling tasks following blood pressure measurement and their accuracy of emotion recognition and average response times were compared. The normotensives demonstrated a significantly higher accuracy of emotion recognition than the prehypertensives and the hypertensives in labelling of facial emotions. This difference generalised to the task where two facial halves (upper & lower) had to be matched on the basis of emotions. In neither the labelling nor matching emotion conditions did the groups differ in their speed of emotion processing. Findings of the present study extend reports of 'emotional dampening' to hypertensives as well as to those at-risk for developing hypertension (i.e. prehypertensives) and have important implications for understanding the psychological component of such medical conditions as hypertension.

Alexithymic trait is associated with right IFG and pre-SMA activation in non-emotional response inhibition in healthy subjects

Event-related fMRI studies have explored emotion inhibitory processes in alexithymic individuals and have demonstrated abnormal BOLD activations in the processing of emotional stimuli. So far, no study has explored the relationship between the alexithymic trait and the general inhibition process, namely utilizing stimuli devoid of emotional valence. In this study 26 healthy subjects were administered the Toronto Alexithymic Scale (TAS-20) questionnaire to measure the alexithymic trait and performed an event related Go/Nogo task build up with letters during fMRI acquisition. We found no correlation between the TAS-20 z-score and the reaction times during the Go/Nogo task. Conversely, we observed a positive correlation between the degree of alexithymic trait -measured with the TAS-20 and the Nogo-Go activation of the right Inferior Frontal Gyrus and the right pre-Supplementary Motor Area. These data suggest that the general process of response inhibition may be modulated by the individual degree of alexithymic trait. We propose that such a relationship could reflect a compensatory mechanism implemented by participants with higher degree of alexithymic trait to reach a correct inhibition.

High Prevalence of Insecure Attachment in Patients with Primary Hypertension

Hypertension is a major cardiovascular (CV) risk factor and is predicted by heightened CV reactivity to stress in healthy individuals. Patients with hypertension also show an altered stress response, while insecure attachment is linked to a heightened stress reactivity as well. This is the first study aiming to assess attachment representations in patients with primary hypertension and to investigate their CV responses when their attachment system is activated. We studied 50 patients (38 men, 12 women) with primary hypertension. The Adult Attachment Projective Picture System (AAP), a widely used and validated interview, was performed to measure the patients' attachment representations, and to activate their attachment system. Blood pressure and heart rate were measured after 10 min at rest prior to and directly after the AAP interview. Mood and state anxiety were assessed using the Multidimensional Mood State Questionnaire (MDBF) and the State Trait Anxiety Inventory-State (STAI-S) before and after the experiment. The prevalence of insecure attachment (dismissing, preoccupied, unresolved) in hypertensive patients was predominant (88%), while in non-clinical populations, only about 50% of individuals had insecure attachment patterns. Blood pressure (p < 0.001), heart rate (p = 0.016), and rate pressure product (p < 0.001) significantly increased in response to the attachment interview. Secure attached patients showed the highest rise in systolic blood pressure (p = 0.020) and the lowest heart rate compared to the other attachment groups (p = 0.043). However, attachment representation showed no significant group or interaction effects on diastolic blood pressure (DBP) and rate pressure product. Insecure attachment was highly over-represented in our sample of patients with primary hypertension. Additionally, a robust CV response to the attachment-activating stimulus was observed. Our data suggest that insecure attachment is significantly linked to primary hypertension, which implies the need for further investigations to evaluate attachment insecurity as a possible risk factor for hypertension.

How is emotional awareness related to emotion regulation strategies and self-reported negative affect in the general population?

Objective

The Levels of Emotional Awareness Scale (LEAS) as a performance task discriminates between implicit or subconscious and explicit or conscious levels of emotional awareness. An impaired awareness of one's feeling states may influence emotion regulation strategies and self-reports of negative emotions. To determine this influence, we applied the LEAS and self-report measures for emotion regulation strategies and negative affect in a representative sample of the German general population.

Sample and Methods

A short version of the LEAS, the Hospital Anxiety and Depression Scale (HADS) and the Emotion Regulation Questionnaire (ERQ), assessing reappraisal and suppression as emotion regulation strategies, were presented to N = 2524 participants of a representative German community study. The questionnaire data were analyzed with regard to the level of emotional awareness.

Results

LEAS scores were independent from depression, but related to self-reported anxiety. Although of small or medium effect size, different correlational patters between emotion regulation strategies and negative affectivity were related to implict and explict levels of emotional awareness. In participants with implicit emotional awareness, suppression was related to higher anxiety and depression, whereas in participants with explicit emotional awareness, in addition to a positive relationship of suppression and depression, we found a negative relationship of reappraisal to depression. These findings were independent of age. In women high use of suppression and little use of reappraisal were more strongly related to negative affect than in men.

Discussion

Our first findings suggest that conscious awareness of emotions may be a precondition for the use of reappraisal as an adaptive emotion regulation strategy. They encourage further research in the relation between subconsious and conscious emotional awareness and the prefarance of adaptive or maladaptive emotion regulation strategies The correlational trends found in a representative sample of the general population may become more pronounced in clinical samples.

Alexithymia and its impact on quality of life in a group of Brazilian women with migraine without aura

Background

Migraine is a type of primary headache widely known for its impact on quality of life of patients. Although the psychological aspects of the disease are receiving increasing attention in current research, some of them, as alexithymia, are still seldom explored. This study aimed to provide evidence on the relationships between markers of depression, anxiety, alexithymia, self-reflection, insight and quality of life in migraine.

Methods

Forty female outpatients from a Brazilian specialized headache hospital service and a paired control group were compared.

Results

The results revealed that women with migraine had higher levels of depression, anxiety and alexithymia, and lower levels of quality of life, self-reflection and insight, compared to controls. Quality of life in women with migraine was predicted by levels of depression and one alexithymia factor (ability to express emotions and fantasies). A binary regression analysis between clinical and control groups revealed the migraine group to comprise individuals with high anxiety, low quality of life in the physical domain and the presence of a concrete thinking style.

Conclusions

The results highlight the relevance of considering psychological variables in the routine healthcare practices for migraine patients in general, while keeping steady attention to individual case features.

Occupational status moderates the association between current perceived stress and high blood pressure: evidence from the IPC cohort study

Although lay beliefs commonly relate high blood pressure (BP) to psychological stress exposure, research findings are conflicting. This study examined the association between current perceived stress and high BP, and explored the potential impact of occupational status on this association. Resting BP was measured in 122 816 adults (84 994 men), aged ≥30 years (mean age±standard deviation: 46.8±9.9 years), without history of cardiovascular and renal disease and not on either psychotropic or antihypertensive drugs. High BP was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg. Perceived stress in the past month was measured with the 4-item perceived stress scale. A total of 33 154 participants (27.0%) had high BP (151±14/90±9 mm Hg). After adjustment for all variables except occupational status, perceived stress was associated with high BP (odds ratio [OR] for a 5-point increase: 1.06; 95% confidence interval [CI]: 1.03-1.09). This association was no longer significant after additional adjustment for occupational status (OR: 1.01; 95% CI: 0.99-1.04). There was a significant interaction (P<0.001) between perceived stress and occupational status in relation to BP: perceived stress was negatively associated with high BP among individuals of high occupational status (OR: 0.91; 95% CI: 0.87-0.96), but positively associated among those of low status (OR: 1.10; 95% CI: 1.03-1.17) or unemployed (OR: 1.13; 95% CI: 1.03-1.24). Sensitivity analyses yielded similar results. The association between current perceived stress and BP depends on occupational status. This interaction may account for previous conflicting results and warrants further studies to explore its underlying mechanisms.

From Brain to Behavior: Hypertension's Modulation of Cognition and Affect

Accumulating evidence from animal models and human studies of essential hypertension suggest that brain regulation of the vasculature is impacted by the disease. Human neuroimaging findings suggest that the brain may be an early target of the disease. This observation reinforces earlier research suggesting that psychological factors may be one of the many contributory factors to the initiation of the disease. Alternatively or in addition, initial blood pressure increases may impact cognitive and/or affective function. Evidence for an impact of blood pressure on the perception and experience of affect is reviewed vis-a-vis brain imaging findings suggesting that such involvement in hypertensive individuals is likely.

Impairment of conflict processing in alexithymic individuals

Alexithymia is characterized by difficulties in identifying and describing feelings and in distinguishing between feelings and bodily sensations. Several researchers have examined the impairment of executive functioning in alexithymia; however, only a few studies have been specifically concerned with conflict processing in alexithymia. Utilizing the attention network test (ANT), we investigated whether alexithymia is related to or independent of executive function, especially with respect to conflict processing. Participants included 33 subjects with high alexithymia scores on the 20-item Toronto Alexithymia Scale (TAS-20) and 30 matched subjects with low alexithymia scores. On the ANT, we found a significant difference between the two groups in conflict processing, and no significant difference in alerting and orienting dimensions. These findings suggested that subjects with high alexithymia scores have selective impairment in conflict processing.

Psychological assessment of primary aldosteronism: a controlled study

OBJECTIVE

Our objective was to investigate psychological correlates in a population with primary aldosteronism (PA) using methods found to be sensitive and reliable in psychosomatic research.

METHODS

Twenty-three PA patients (12 male, 11 female; mean age 50 ± 9 yr) were compared with 23 patients with essential hypertension (EH) (15 male, eight female; mean age 47 ± 8 yr) and 23 matched normotensive subjects. A modified version of the Structural Clinical Interview for DSM-IV, a shortened version of the structured interview for the Diagnostic Criteria for Psychosomatic Research, and two self-rating questionnaires, the Psychosocial Index and the Symptom Questionnaire, were administered.

RESULTS

Twelve of 23 patients with PA (52.2%) suffered from an anxiety disorder compared with four of 23 with EH (17.4%) and one control (4.3%) (P < 0.001). Generalized anxiety disorder was more frequent in PA than in EH patients and controls (P < 0.05). As assessed by Diagnostic Criteria for Psychosomatic Research, irritable mood was more frequent in PA and EH compared with controls (P < 0.05) but did not differentiate PA from EH. According to Psychosocial Index results, patients with PA had higher levels of stress (P < 0.01) and psychological distress (P < 0.01) and lower level of well-being (P < 0.05) than controls. Compared with EH patients, PA patients had higher scores in stress subscale (P < 0.05). The Symptom Questionnaire showed higher levels of anxiety (P < 0.01), depression (P < 0.01) and somatization (P < 0.01) and lower physical well-being (P < 0.05) in PA than controls.

CONCLUSION

A role of mineralocorticoid regulatory mechanisms in clinical situations concerned with anxiety and stress is suggested.

Differentiation in the momentary rating of somatic symptoms covaries with trait emotional awareness in patients at risk for sudden cardiac death

OBJECTIVES

Somatic symptom ratings covary with neuroticism. Yet, people vary from one another in their ability to report their own emotions and differentiate them from bodily sensations. We hypothesized that stressed individuals with greater emotional awareness would experience somatic symptoms in a more differentiated way independent of neuroticism.

METHODS

Over 3 days, ecological momentary assessments were completed in 161 patients (72.6% female; mean age, 35 years) with Long QT Syndrome, a genetic disorder associated with increased risk for sudden cardiac death. Patients were paged randomly ten times per day to report their momentary experience of nine somatic symptoms (e.g., headache, sore throat, tiredness) as well as other variables. We examined the intercorrelation between somatic symptom ratings, reasoning that greater intercorrelation among ratings indicated less differentiation. Subjects completed measures of neuroticism, depression, and the Levels of Emotional Awareness Scale, a trait measure of the tendency to experience emotions in a complex and differentiated way.

RESULTS

Higher Levels of Emotional Awareness Scale-Self scores were associated with greater differentiation in the momentary rating of somatic symptoms (p < .001) in men and women independently. This association did not change after removing variance due to neuroticism, depression, or symptom intensity.

CONCLUSIONS

Among individuals stressed by having a life-threatening condition, those who are more emotionally aware report somatic symptoms in a more differentiated way. These findings regarding symptoms largely unrelated to the disorder are consistent with other evidence that medically unexplained physical symptoms, which tend to be nonspecific, may be accompanied by relatively undifferentiated negative affect.
