Heterogeneity of emotional and interpersonal difficulties in alcohol-dependence: A cluster analytic approach

Alcohol-related brain damage: an umbrella (term) for the approaching post-COVID monsoon

Individuals with alcohol-related brain damage (ARBD) represent a population whose healthcare needs often go unmet. This is the result of a lack of not only an awareness surrounding the condition by healthcare professionals, but also healthcare service inclusion and delivery, more broadly. The Coronavirus 2019 (COVID-19) pandemic and the associated lockdowns dramatically affected the accessibility and availability of addiction services globally, while also driving changes in alcohol consumption among the most vulnerable. In the absence of change, this culmination of increased high-risk drinking behaviour, lack of awareness by healthcare professionals and severely limited service delivery for individuals living with ARBD post COVID-19, represents a perfect storm that is rapidly approaching our health and care services world-wide. Collectively, this will reduce positive health outcomes in an already at-risk group.

Effects of alcohol problem discrepancy on relationship adjustment: The moderating role of conflict negotiation among couples with alcohol use disorder and intimate partner violence

Alcohol use disorder (AUD) has well-known negative effects on romantic relationship functioning, including the occurrence of intimate partner violence (IPV). A separate literature focused on community couples indicates that relationship functioning is more likely to suffer when partners report greater discrepancies in alcohol consumption. It is important to expand this literature to couples with AUD and to examine the role of impactful AUD domains in dyadic functioning. Furthermore, few studies have examined adaptive, treatment-malleable factors that could potentially offset the negative impact of alcohol discrepancies on relationship functioning. This study examined the association between couples' alcohol problem discrepancies and relationship adjustment, as well as the moderating effect of self-reported adaptive conflict negotiation behaviors. Participants were 100 couples (N = 200 individual participants) with intimate partner violence wherein at least one partner met diagnostic criteria for AUD. Actor-Partner Interdependence Models indicated that greater alcohol problem discrepancy was associated with lower dyadic adjustment. Moderation analyses revealed that the highest level of relationship adjustment was observed among couples with lower alcohol problem discrepancy and greater negotiation behaviors, while relationship adjustment was similar for couples with larger alcohol problem discrepancy, regardless of negotiation behaviors. Although further study is needed to clarify under what specific conditions adaptive negotiation behaviors are most helpful, they appear to be beneficial for some couples in this sample. We found no evidence that negotiation behaviors may be harmful among these high-risk couples.

Association between alexithymia and substance use: A systematic review and meta-analysis

Alexithymia has been associated with substance use, but the magnitude of the association has not been evaluated and sub-group differences, if any, are unknown. The aim of this meta-analysis is to systematically review the association between alexithymia and substance use (alcohol or illicit drugs). We identified studies through a systematic review of PubMed and Web of Science and obtained a total of 52 publications using the Toronto Alexithymia Scale-20 scale. Random effects meta-analysis was used to evaluate the overall and sub-group associations. Of the studies, 50 were cross-sectional and two longitudinal. Alexithymia was associated with any substance use (Cohen's d = 0.62, 95% confidence interval [CI] 0.49-0.76), with little difference between estimates for use of alcohol or illicit drugs. A stronger association was observed for the alexithymia dimension "Difficulty in Identifying Feelings" (d = 0.64, 95% CI = 0.47-0.81) and "Difficulty in Describing Feelings" (d = 0.44, 95% CI = 0.32-0.55) than for "Externally Oriented Thinking" (d = 0.19, 95% CI = 0.09-0.28). The association was stronger in studies with clinical patient populations (d = 0.83, 95% CI = 0.62-1.05) than in those investigating general or student populations, and in studies with a majority of male rather than female participants. These findings suggest a strong overall association between alexithymia and substance use and a very strong association among clinical patient populations. The association may be stronger with the emotion-related dimensions than with the cognition-related dimension of alexithymia. As nearly all the studies were cross-sectional, more longitudinal studies are needed.

Faux Pas Recognition and Executive Processes in Patients with Alcohol Use Disorder: Toward an Investigation of Interindividual Heterogeneity

OBJECTIVE

Impairment of executive functions (EF) has been documented for decades in patients with alcohol use disorders (AUD), while more recent studies have also reported impaired theory of mind. Both have been associated with negative outcomes, particularly a high risk of relapse. However, the interrelatedness of EF and theory of mind impairments remains subject to debate.

METHOD

About 19 AUD outpatients and 20 healthy controls (HC) were asked to complete measures of motor inhibition, mental flexibility, and updating to assess EF, and the faux pas test to assess theory of mind.

RESULTS

As expected, patients' mean performances on EF and faux pas measures were poorer than those of HC. Correlational analyses revealed that executive processes were differentially related to faux pas subscores. Additional single-case analyses corroborated the strong association between EF and faux pas interpretation, as patients with AUD mostly had congruent performances (i.e., both EF and faux pas impaired or both EF and faux pas preserved).

CONCLUSIONS

This study highlights the interrelatedness of EF and faux pas performances in AUD, but also emphasizes the incomplete overlap of the cognitive processes involved in these tasks, with heterogeneous patterns of association. Based on these findings, tailored cognitive rehabilitation programs that simultaneously target EF and faux pas recognition could be developed to favor patients' social inclusion and reduce the risk of relapse. Results also argue in favor of systematic screening for EF and theory of mind impairments among AUD patients.

An exploration of theory of mind performance among men convicted of rape

Several of the known risk factors for sexual violence concern a lack of capacity for engaging in mutually satisfying interpersonal relationships. Socio-cognitive deficits may be approached from a theory of mind (ToM) perspective, where lack of ability to attribute mental states to others is seen as the core feature. This study focuses on imprisoned men (n = 26) convicted of rape against an adult. A video-based measure of ToM (MASC) was applied, depicting social interaction in a dynamic real-life setting. The results showed that the rape-convicted men have a markedly inferior ability to infer the mental states of others. Clinical as well as theoretical implications of the findings are discussed.

Emotional processes in binge drinking: A systematic review and perspective

Binge drinking is a widespread alcohol consumption pattern commonly engaged by youth. Here, we present the first systematic review of emotional processes in relation to binge drinking. Capitalizing on a theoretical model describing three emotional processing steps (emotional appraisal/identification, emotional response, emotional regulation) and following PRISMA guidelines, we considered all identified human studies exploring emotional abilities among binge drinkers. A literature search was conducted in PubMed, Scopus, and PsychINFO, and a standardized methodological quality assessment was performed for each study. The main findings offered by the 43 studies included are: 1) regarding emotional appraisal/identification, binge drinking is related to heightened negative emotional states, including greater severity of depressive and anxiety symptoms, and have difficulties in recognizing emotional cues expressed by others; 2) regarding emotional response, binge drinkers exhibit diminished emotional response compared with non-binge drinkers; 3) regarding emotional regulation, no experimental data currently support impaired emotion regulation in binge drinking. Variability in the identification and measurement of binge drinking habits across studies limits conclusions. Nevertheless, current findings establish the relevance of emotional processes in binge drinking and set the stage for new research perspectives to identify the nature and extent of emotional impairments in the onset and maintenance of excessive alcohol use.

Correlates of emotional intelligence among Lebanese adults: the role of depression, anxiety, suicidal ideation, alcohol use disorder, alexithymia and work fatigue

BACKGROUND

Relationship between emotional intelligence and emotional variables such as stress, depression, anxiety and mental health has been well documented in child and adult samples. New insights into the association between emotional intelligence and different components of mental health in one study (cognitive, emotional and behavioral dimensions) can help patients, therapists, relatives, and friends to understand, explain, and cope with symptoms. There have been no studies assessing the association between the emotional intelligence (EI) with various factors in Lebanon. This study principal aim was to evaluate how EI is related to mental health issues: social anxiety, depression, alcohol use disorders (AUD), work fatigue, stress and alexithymia in Lebanon.

METHODS

789 participants were enrolled in a cross-sectional study between November 2017 and March 2018. A cluster analysis was used to evaluate participants' profiles with the help of emotional intelligence subscales, to separate the Lebanese population into equal limited units with different characteristics using the K-mean technique.

RESULTS

Three clusters were computed dividing participants into low EI (cluster 1; 24.5%), moderate EI (cluster 2; 43.7%) and high EI (cluster 3; 31.7%) respectively. Fitting into the cluster 1 (low EI) was significantly associated with higher AUD, alexithymia, anxiety, depression, perceived stress, social phobia, emotional, mental and physical work fatigue, suicidal ideation compared to cluster 3 (high EI). Fitting into the cluster 2 (moderate EI) was significantly correlated with higher AUD, depression, alexithymia, anxiety, perceived stress, social phobia, mental work fatigue and suicidal ideation compared to cluster 3 (high EI).

CONCLUSION

This study results suggest that emotional intelligence is related to different variables, warranting interventions to limit/decrease alcohol abuse and mental/psychological illnesses as much possible.

Tackling heterogeneity: Individual variability of emotion decoding deficits in severe alcohol use disorder

BACKGROUND

Severe alcohol use disorder (SAUD) is associated with social cognition deficits. Patients with SAUD are impaired for the recognition of emotional facial expressions, particularly at early stages of abstinence. These deficits damage interpersonal relations and increase relapse risk. However, uncertainties still abound on their variation across emotions and on the heterogeneity of emotional impairments across patients. We addressed these questions by exploring how the deficit varies according to emotions' type/intensity and patients' heterogeneity.

METHODS

Sixty-five recently detoxified patients with SAUD and 65 matched healthy controls performed the Facial Emotion Recognition Test, assessing the ability to identify six emotions (anger, contempt, disgust, fear, happiness, sadness) displayed by morphed faces with various intensities. Accuracy scores and detection thresholds were collected for each emotion. Beyond group comparisons, multiple single-case analyses determined the percentage of patients presenting decoding deficits for each emotion.

RESULTS

When current depression and anxiety symptoms were controlled for, patients did not present a general emotion decoding deficit, but were rather characterized by specific deficits for disgust/contempt in accuracy, and for disgust in detection threshold scores. Single-case analyses showed that only a third of patients presented a clinically significant emotional deficit.

CONCLUSIONS

Patients with SAUD only present emotional decoding deficits for specific interpersonal emotions (disgust/contempt) when subclinical psychopathological states are controlled for, and show no general emotional impairment. This goes against the proposal of a generalized social cognition deficit in this population. This group effect moreover masks a massive heterogeneity across patients, which has implications at experimental and clinical levels.

Childhood trauma, alexithymia, and mental states recognition among individuals with alcohol use disorder and healthy controls

BACKGROUND

Although prior work indicates a link between childhood trauma, alexithymia, and mental states recognition, empirical support is limited. Moreover, findings based on adult samples are mixed. Previous studies demonstrate that childhood trauma might either enhance, preserve, or reduce mental states recognition in selected at-risk populations. The current study investigates whether alcohol use disorder (AUD) status moderates the association between childhood trauma, alexithymia, and mental states recognition in a treatment-seeking AUD sample and non-AUD healthy adults.

METHODS

Data comes from 255 individuals participating in an ongoing project that compares emotional and behavioral functioning of patients treated in an inpatient setting for AUD and a comparison sample of 172 healthy controls (HCs). Mental states recognition was measured using a computerized version of the Reading the Mind in the Eyes Task (RMET). The presence of childhood trauma was assessed with the Childhood Trauma Questionnaire. Alexithymia was measured with the Toronto Alexithymia Scale (TAS-20). Demographic information, as well as alcohol drinking and psychopathological symptoms were assessed. A moderated mediation model was estimated whereby alexithymia was included as a mediator in the association between childhood trauma and RMET performance, with AUD diagnosis status moderating the link between alexithymia and RMET performance.

RESULTS

Findings provide support for moderated mediation. Childhood emotional trauma impacted negative mental states recognition performance via difficulty describing feelings, but only among HCs (p < 0.01).

CONCLUSIONS

Findings highlight the impact that AUD status has on the association between early life emotional trauma and difficulty describing feelings on individual differences in mental states recognition.

Heterogeneity of Executive Function Abilities in Recently Detoxified Patients with Alcohol Use Disorder: Evidence from a Cluster Analysis

BACKGROUND

Impairments of executive functions (EF) have been consistently reported in patients with alcohol use disorder (AUD), mostly in studies which were based on comparisons of means between groups. However, given the high heterogeneity in AUD patients, this approach could actually cover a wide range of EF patterns. In the present study, we addressed the paucity of the literature about cognitive heterogeneity in AUD by applying a cluster analytical approach on EF measures.

METHODS

Seventy-eight withdrawn AUD patients and 77 healthy Control participants completed measures targeting a variety of EF components. We then used cluster analysis to identify subgroups of AUD patients. Furthermore, the AUD subgroups were compared to the Control group to establish their specific EF patterns.

RESULTS

Findings showed that AUD patients could be divided into 3 clusters based on their EF performances. A first cluster accounting for half of the AUD sample was characterized by unimpaired EF (Cluster 1). The 2 other clusters displayed major EF deficits but differed regarding the deficient EF component. While Cluster 2 was mainly impaired on measures of rule deduction and mental flexibility, Cluster 3 was mainly characterized by a lower processing speed and impaired inhibition of an ongoing motor response. Differences in EF performances of AUD patients could be related to differences in premorbid cognitive reserve, impulsiveness patterns, and withdrawal complications.

CONCLUSIONS

This study highlights the importance of the cognitive heterogeneity in AUD by showing that AUD patients display substantially different EF patterns. Future studies should try to go beyond mere group comparisons to further deepen our understanding about cognitive differences between AUD patients. In the long run, this could lead to more personalized prevention and treatment programs specifically tailored to the patient's impairments.

Selective visual and crossmodal impairment in the discrimination of anger and fear expressions in severe alcohol use disorder

BACKGROUND

Severe alcohol use disorder (SAUD) is associated with impaired discrimination of emotional expressions. This deficit appears increased in crossmodal settings, when simultaneous inputs from different sensory modalities are presented. However, so far, studies exploring emotional crossmodal processing in SAUD relied on static faces and unmatched face/voice pairs, thus offering limited ecological validity. Our aim was therefore to assess emotional processing using a validated and ecological paradigm relying on dynamic audio-visual stimuli, manipulating the amount of emotional information available.

METHOD

Thirty individuals with SAUD and 30 matched healthy controls performed an emotional discrimination task requiring to identify five emotions (anger, disgust, fear, happiness, sadness) expressed as visual, auditory, or auditory-visual segments of varying length. Sensitivity indices (d') were computed to get an unbiased measure of emotional discrimination and entered in a Generalized Linear Mixed Model. Incorrect emotional attributions were also scrutinized through confusion matrices.

RESULTS

Discrimination levels varied across sensory modalities and emotions, and increased with stimuli duration. Crucially, performances also improved from unimodal to crossmodal conditions in both groups, but discrimination for anger crossmodal stimuli and fear crossmodal/visual stimuli remained selectively impaired in SAUD. These deficits were not influenced by stimuli duration, suggesting that they were not modulated by the amount of emotional information available. Moreover, they were not associated with systematic emotional error patterns reflecting specific confusions between emotions.

CONCLUSIONS

These results clarify the nature and extent of crossmodal impairments in SAUD and converge with earlier findings to ascribe a specific role for anger and fear in this pathology.

Relationship Between Alcohol-related Family Adversity, Alcohol Use Across Adolescence, and Mental States Recognition in Young Adulthood

OBJECTIVES

Although a theoretical link between childhood adversity and mental states recognition has been established, empirical findings are mixed. Some prior work indicates that childhood adversity might enhance, preserve, or reduce mentalization skills in selected at-risk populations. In the current study, we examine whether the presence of risky alcohol use during adolescence moderates the association between childhood alcohol-related family adversity and mental states recognition in young adulthood.

METHODS

Secondary data analysis was conducted on 266 young adults who participated in the Michigan Longitudinal Study-a multiwave prospective study on at-risk youth. Children were assessed after initial recruitment (wave 1, target child age range 3-5 years), with assessments repeated every 3 years using parallel measures. The current study focuses on data spanning wave 2 (age range 7-9 years) through wave 6 (target child age range 18-21 years). A family adversity index was derived reflecting exposure to a maladaptive family environment during childhood as assessed at wave 1. An alcohol use risk factor was established reflecting early problem alcohol use during adolescence (target child age range 12-17 years). Mental states recognition was measured with a computerized version of the Reading the Mind in the Eyes Task (RMET) at wave 6. Information about demographics, psychopathological symptoms, and IQ was obtained. The alcohol use risk factor was tested as a potential moderator of the association between childhood family adversity on RMET performance during young adulthood.

RESULTS

Alcohol use risk moderated the relationship between childhood alcohol-related family adversity, and negative and neutral mental states recognition. Specifically, childhood family adversity was positively associated with neutral mental states recognition among participants high in alcohol risk (P = 0.03) and positively associated with negative mental states recognition among participants at average (P = 0.02) and high (P = 0.002) levels of alcohol risk.

CONCLUSIONS

Findings indicate that history of childhood adversity may actually improve young adult negative and neutral mental states recognition among those demonstrating high levels of risky alcohol use, as substance use may serve as an external self-regulatory tool. Clinical interventions that target enhancing metacognitive competence and emotion regulation could ultimately help to break the cycle of alcohol-related family adversity.

Disrupted Fear and Sadness Recognition in Binge Drinking: A Combined Group and Individual Analysis

BACKGROUND

Binge drinking is a harmful pattern of alcohol consumption, associated with cognitive and cerebral impairments. Indeed, various cognitive processes have been identified as disrupted in binge drinking, ranging from perceptive to executive functions, but emotional processes have conversely been little investigated. Particularly, it is unclear to what extent binge drinkers (BD) present difficulties to recognize and categorize the emotions expressed by other individuals. Such an exploration would, however, offer a more comprehensive view of the deficits associated with alcohol-related disorders and potentially involved in the maintenance of this harmful habit.

METHODS

Fifty-two BD and 42 control participants performed an emotional task assessing the ability to recognize 6 basic emotions (i.e., anger, contempt, disgust, fear, happiness, and sadness). Accuracy score and detection threshold were collected for each emotion. To explore the extent of emotion recognition difficulties, 2 analyses were conducted: (i) classical repeated measures analyses of variance, to compare groups' performance, and (ii) multiple single-case analyses (i.e., Crawford's t-tests), to determine the percentage of BD presenting genuine emotion recognition deficits. Correlations were also performed between alcohol consumption characteristics and emotional recognition scores.

RESULTS

BD presented reduced performance for the recognition of fear and sadness. Multiple single cases highlighted that these deficits respectively concerned 21.15 and 15.38% of the binge drinking sample, and the relation between binge drinking and reduced sadness detection was supported by correlational analyses.

CONCLUSIONS

These findings show that binge drinking is associated with a disrupted processing of emotional stimuli. By identifying heterogeneity in the impairments presented by BD, the present results also underline the usefulness of a combined group and individual Analysis.

Interpersonal and intrapersonal emotional processes in individuals treated for alcohol use disorder and non-addicted healthy individuals

INTRODUCTION

Prior work largely confirms the presence of various emotional processing deficits among individuals with an alcohol use disorder (AUD); however, their specificity and relevance still warrant investigation. The aim of the current study was to compare selected aspects of emotional processing (i.e., mental state recognition, alexithymia, and emotional intelligence) between individuals treated for an AUD and healthy individuals.

METHODS

The AUD sample consisted of 92 abstinent men with AUD who were participating in an 8-week inpatient abstinence-based treatment program in Warsaw, Poland. The healthy control (HC) group consisted of 86 men recruited from the Medical University of Warsaw and the Nowowiejski Hospital administrative staff. Baseline information about demographics, psychopathological symptoms, and severity of alcohol problems was obtained. Mental states recognition was assessed using the Reading the Mind in the Eyes Test (RMET). Alexithymia was measured with the Toronto Alexithymia Scale (TAS-20). The Schutte Self-Report Emotional Intelligence Test (SSEIT) was used to measure emotional intelligence (EI).

RESULTS AND CONCLUSIONS

After accounting for potentially confounding variables (demographics, severity of depression, anxiety symptoms) in MANCOVA models, patients with AUD presented deficits in identification and description of their own emotional states, as well as lower emotion regulation skills when compared to HCs. No between-group differences were observed in self-reported recognition of other people's emotions, social skills, and a behavioral measure of mental states recognition. Specific rather than general emotion-processing deficits in participants with AUD were identified, suggesting problems with processing of intrapersonal emotional signals.
