Alexithymia in individuals maltreated as children and adolescents: a meta-analysis

A national survey of pandemic fear and cyberchondria after ending zero-COVID policy: The chain mediating role of alexithymia and psychological distress

BACKGROUND

More than half the domestic population in China were infected with COVID-19 in two months after ending "zero-infection policy", which severely overwhelmed frontline healthcare providers with stress and fear. However, there is no study to date investigating the associations between nurses' fear of pandemic and cyberchondria. This study aimed to 1) investigate the correlations between fear pandemic and cyberchondria among frontline nurses, and 2) discover its potential mechanism.

METHODS

A cross-sectional sample of frontline nurses (N = 8161) was recruited from 98 hospitals across China in February 2023. Participants were invited to complete an online, self-rated standardized questionnaire focused on pandemic fear, alexithymia, psychological distress, and cyberchondria. Environmental, clinical and socioeconomic information were collected for adjustment while conducting chain mediation analysis.

RESULTS

When other covariates were controlled, it was found that fear of the pandemic significantly contributed to cyberchondria (b = 0.58, 95%CI [0.56, 0.60], p < .001). The chain mediation model suggested that both alexithymia and psychological distress were mediating factors between pandemic fear and cyberchondria.

CONCLUSIONS

The higher the perceived fear, the greater the cyberchondria, which suggests that reducing fear about the pandemic and providing adequate support could reduce the incidence of cyberchondria. As alexithymia and psychological distress may be transdiagnostic mechanisms between fear and cyberchondria, targeted interventions focused on expression dysregulation and emotional identification could be useful.

The Bridge Between Childhood Trauma and Alexithymia Among Adolescents with Depressive and Bipolar Disorders: A Network Bridge Analysis

Childhood trauma and alexithymia are significant risk factors for adolescent mental health issues. Prior research has linked these factors to psychopathology, but the complexities of their interrelation remain underexplored. This study aims to elucidate the relationship between various forms of childhood trauma and alexithymia in adolescents with depressive and bipolar disorders. Structural Equation Modeling (SEM) and network analysis were utilized on data from 2343 Chinese adolescents (aged 12-18 years, 77.93% female) diagnosed with depression or bipolar disorder. Measures included the Childhood Trauma Questionnaire (CTQ) and the Toronto Alexithymia Scale (TAS-20). SEM demonstrated a significant correlation between childhood trauma and alexithymia. Network analysis identified emotional abuse and difficulty identifying feelings as central nodes. Emotional abuse emerged as a key factor for difficulty in emotional identification among adolescents. This study highlights the need for early intervention and the importance of emotional nurturing in childhood to prevent long-term socioemotional difficulties.

Alexithymia as a mediator between adverse childhood events and the development of psychopathology: a meta-analysis

Introduction

Victims of child abuse have an elevated risk of developing mental health issues later in life. Several variables have been suggested as mediators of this correlation, but little is known about the possible influence of alexithymia. Alexithymia is a sub-clinical personality trait that manifests as difficulties recognizing and verbalizing emotions.

Methods

In this study, two separate meta-analyses were conducted using questionnaire data, and Pearson correlations for overall effects were estimated.

Results

The correlation between child abuse and alexithymia showed to be significant (r = .26), as did the correlation between alexithymia and general psychopathology (r = .44). Further analyses revealed no indication for possible publication bias. When investigating differences between various subtypes of child maltreatment, each subtype significantly correlated with alexithymia. Emotional abuse, emotional neglect, and physical neglect had stronger correlations than physical and sexual abuse.

Discussion

These results suggest that alexithymia plays a mediating role, at least in part, in the relationship between experiences of child abuse and general psychopathology in adulthood. Therefore, alexithymia may be relevant to further research and deserves attention in the prevention of and therapy for mental health issues in victims of child abuse.

Investigating the role of alexithymia in the association between cumulative childhood maltreatment and teen dating violence victimization

BACKGROUND

Childhood maltreatment is increasingly recognized as an important risk factor for teen dating violence (TDV) victimization. However, far too little research has studied the mechanisms that could explain this higher risk of revictimization. The present study investigated the role of alexithymia in the association between cumulative childhood maltreatment, TDV victimization occurrence and chronicity, and TDV-related post-traumatic stress disorder (PTSD) symptoms.

METHODS

A total of 2780 adolescents, aged 13 to 19, completed measures of childhood maltreatment and alexithymia at Time 1 and TDV victimization and TDV-related PTSD symptoms at Time 2 (6 months later). Two mediational models were tested to examine the role of alexithymia as a risk factor for revictimization. One model assessed TDV occurrence as an outcome, while the other explored TDV chronicity and TDV-related PTSD symptoms as outcomes.

RESULTS

Findings suggest that cumulative childhood maltreatment is associated with an increased probability of TDV occurrence through alexithymia. Cumulative childhood maltreatment and alexithymia are also associated with TDV chronicity and TDV-related PTSD symptoms. Notably, cumulative childhood maltreatment is associated with higher levels of alexithymia among adolescent victims of TDV, which, in turn, predicts higher TDV chronicity and TDV-related PTSD symptoms.

LIMITATIONS

This study relied on abbreviated measures and did not include all forms of child maltreatment (e.g., emotional and physical neglect).

CONCLUSIONS

Promoting emotional awareness and identification among youth victims of child maltreatment could reduce the risk of TDV occurrence, TDV chronicity, and TDV-related PTSD symptoms.

Alexithymia as a mediator of the associations between child maltreatment and internalizing and externalizing behaviors in adolescence

Child maltreatment is a global concern that profoundly affects individuals throughout their lives. This study investigated the relationships between various forms of child maltreatment and behavior problems involving internalization and externalization during adolescence. Data obtained from a diverse sample of 1802 Canadians aged 14-18 years was used to examine the mediating role of alexithymia-a difficulty in recognizing and expressing emotions-in these associations. Results indicated that adolescents who experienced sexual abuse, emotional abuse, and exposure to intimate partner violence (IPV) in their childhood exhibited higher levels of alexithymia, which was correlated with elevated levels of both internalizing and externalizing problems. Physical abuse and parental neglect were only associated with externalizing problems. Gender differences also emerged, with gender-diverse adolescents reporting a higher prevalence of maltreatment, alexithymia, and behavior problems compared with their peers. However, alexithymia's mediating role was consistent across genders. Overall, this study highlights the intricate relationships between child maltreatment, alexithymia, and adolescent behavior problems. The findings of this study how different forms of child maltreatment significantly shape behavioral outcomes and indicate the importance of interventions in enhancing emotional awareness and expression in adolescents with a childhood history of maltreatment.

Traits linked to sensory processing sensitivity mediate the relationship between externally oriented thinking and fantasizing

Introduction

Alexithymia is characterized by difficulties identifying and describing feelings but expression of externally oriented thinking (EOT) and difficulty fantasizing is more variable. In two studies, we investigated whether links between EOT and fantasizing are mediated by sensory processing sensitivity (SPS).

Methods

University students completed measures of alexithymia, SPS, and fantasizing.

Results

In Study 1 (N = 700) we identified two clusters of SPS traits: a positive facet (sensitivity to subtle stimuli) and a negative facet (sensitivity to uncomfortable stimuli). In the 499 participants who completed the fantasy measure, low EOT scores predicted stronger SPS positive and negative traits, which predicted a stronger tendency to mentally project oneself into the lives of characters in books, movies, and plays. In Study 2 (N = 600), the link between EOT and this same fantasizing tendency was again mediated by features of SPS-in this case fantasy proneness and emotional reactivity.

Discussion

We suggest that, whereas individuals who score high on EOT have an impoverished fantasy life, those who score relatively low on EOT and turn their attention inward are able to maintain stronger representations of imagined events in working memory (enhancing the likelihood that they will be recalled) and react more strongly to these events (enhancing their salience). Stronger expression of these features of SPS, in turn, increases the likelihood that one will develop a cognitive style that involves the application of imagery-based strategies to support deep processing of the thoughts and feelings of characters depicted in narratives.

Childhood maltreatment and insomnia in college students: The role of alexithymia and psychological distress

Insomnia, which is highly prevalent among college students, has been identified as one of the negative consequences of childhood maltreatment. While prior studies have uncovered distinct correlations between childhood maltreatment, insomnia, and other variables, the potential underlying mechanisms need to be further explored. This study focused on the chain-mediating role of alexithymia and psychological distress in the relationship between childhood maltreatment and insomnia. An online cross-sectional survey was conducted among Chinese college students, yielding 999 valid questionnaires that included demographic information, the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Toronto Alexithymia Scale (TAS), the 21-item Depression Anxiety Stress Scales (DASS-21), and the Insomnia Severity Index (ISI). A chain-mediating model was then tested. The results revealed significant positive correlations between each pair of the four variables. Alexithymia and psychological distress separately mediated the link between childhood maltreatment and insomnia (effect of alexithymia was 0.06 with 95 % CI [0.03, 0.09]; effect of psychological distress was 0.24 with 95 % CI [0.19, 0.29]). Additionally, a chain-mediating effect of alexithymia and psychological distress was observed (chain-mediating effect was 0.12 with 95 % CI [0.09, 0.15]). The findings suggest that emotional interventions may mitigate the long-term effect of childhood maltreatment on sleep problems among college students, by improving the ability to recognize emotions and decreasing emotional problems.

Childhood maltreatment and mentalizing capacity: A meta-analysis

BACKGROUND

The protective role of mentalizing capacity against the adverse effects of childhood maltreatment (CM) is acknowledged; however, empirical studies have yielded diverse conclusions regarding the relationship between childhood maltreatment and mentalizing capacity.

OBJECTIVE

This meta-analytic review aims to comprehensively summarize and quantify the association between childhood maltreatment and mentalizing capacity.

PARTICIPANTS AND SETTING

A total of 23 studies involving 3910 participants were included in the analysis.

METHODS

Systematic searches across eight bibliographic databases identified peer-reviewed publications describing empirical studies on the interplay between CM and mentalizing capacity. Effect sizes (r) were synthesized using random-effects models. A moderated effects analysis was conducted on five variables: participant gender, age group, mental health status, mentalizing capacity measurement, and childhood maltreatment measurement.

RESULTS

The findings showed a significant moderate negative correlation between childhood maltreatment and mentalizing capacity (r = -0.21, 95 % CI = [-0.26, -0.15]). This suggests that heightened severity of childhood maltreatment corresponds to lower mentalizing capacity. Moreover, the strength of this correlation was influenced by participant gender, age group, mental health status, mentalizing capacity measurement, and CM measurement.

CONCLUSIONS

The controversy surrounding the link between CM and mentalizing capacity gains clarity when considering significant moderating variables. The pooled effect provides a preliminary definition of the magnitude and direction of this correlation.

Interactive relationship between alexithymia, psychological distress and posttraumatic stress disorder symptomology across time

Alexithymia, psychological distress, and posttraumatic stress disorder (PTSD) are highly related constructs. The ongoing debate about the nature and relationship between these constructs is perpetuated by an overreliance on cross-sectional research. We examined the longitudinal interactive relationship between alexithymia, psychological distress, and PTSD. We hypothesised that there is an interactive relationship between the three constructs. Military personnel (N = 1871) completed the Toronto Alexithymia Scale, the Kessler 10 and a PTSD Checklist (PCL-C) at pre-deployment, post-deployment, and at 3-4 years following the post-deployment assessment. We initially tested whether psychological distress is either a moderator or mediator in the relationship between alexithymia and PTSD across the time points. General psychological distress was a partial mediator of total PTSD severity and hyperarousal symptomology at all three time points. Psychological distress fully mediated re-experiencing and avoidance symptomology at all three time points. Our results suggest that those with alexithymia are at longitudinal risk of developing more severe PTSD symptomology and experiencing hyperarousal irrespective of temporal proximity to traumatic exposure. Further, vulnerability to the emergence of re-experiencing and avoidance symptomology for those with alexithymia is increased when one experiences greater distress. Our results show that alexithymia is a persistent risk factor for PTSD symptomology.

Isolating unique variance in mental health outcomes attributable to personality variables and childhood emotional abuse

Introduction

University students are at high risk for anxiety and depression. Our main objective was to tease apart variance in symptom severity that was uniquely attributable to four associated variables that are frequently confounded: exposure to childhood emotional abuse, alexithymia, sensory processing sensitivity (SPS), and anxiety sensitivity (AS).

Methods

University students (N = 410) completed an online survey designed to measure our four key study variables along with several other potentially relevant variables including sex, physical activity levels, and perceived COVID-19 impacts.

Results

Over half of the participants reported moderate to extremely severe symptoms of anxiety and depression. Females reported stronger signs of SPS and AS and were more likely than males to have increased their moderate/vigorous exercise since the pandemic began. After controlling for the other variables, the best predictors of perceived COVID-19 impacts were SPS, childhood emotional abuse, and current levels of physical activity. Whereas all three personality variables and childhood emotional abuse emerged as significant predictors of both depression and anxiety, neither COVID-19 impacts nor physical activity levels accounted for unique variance in either model. Unexpectedly, male sex emerged as an additional risk factor for depression, raising the possibility that males experience unique stressors and societal pressures that increase their risk of depression.

Discussion

These findings help to clarify the links between childhood emotional abuse, personality traits implicated in emotional awareness and self-regulation, and mental health. They may have important implications for the development and implementation of individualized treatments for common mental disorders.

How does it feel? An exploration of neurobiological and clinical correlates of alexithymia in trauma-exposed police-officers with and without PTSD

Background: Alexithymia, an inability to recognise one's emotions, has been associated with trauma-exposure and posttraumatic stress disorder (PTSD). Previous research suggests involvement of the oxytocin system, and socio-emotional neural processes. However, the paucity of neurobiological research on alexithymia, particularly in trauma-exposed populations, warrants further investigation.Objective: Explore associations between alexithymia, endogenous oxytocin levels, and socio-emotional brain function and morphometry in a trauma-exposed sample.Method: Dutch trauma-exposed police officers with (n = 38; 18 females) and without PTSD (n = 40; 20 females) were included. Alexithymia was assessed with the Toronto Alexithymia Scale (TAS-20). Endogenous salivary oxytocin was assessed during rest, using radioimmunoassay. Amygdala and insula reactivity to socio-emotional stimuli were assessed with functional MRI, amygdala and insula grey matter volume were derived using Freesurfer.Results: Alexithymia was higher in PTSD patients compared to trauma-exposed controls (F(1,70) = 54.031, p < .001). Within PTSD patients, alexithymia was positively associated with PTSD severity (ρ(36) = 0.497, p = .002). Alexithymia was not associated with childhood trauma exposure (β = 0.076, p = .509), police work-related trauma exposure (β = -0.107, p = .355), oxytocin levels (β = -0.164, p = .161), insula (β = -0.170, p = .158) or amygdala (β = -0.175, p = .135) reactivity, or amygdala volume (β = 0.146, p = .209). Insula volume was positively associated with alexithymia (β = 0.222, p = .016), though not significant after multiple testing corrections. Bayesian analyses supported a lack of associations.Conclusions: No convincing neurobiological correlates of alexithymia were observed with any of the markers included in the current study. Yet, the current study confirmed high levels of alexithymia in PTSD patients, independent of trauma-exposure, substantiating alexithymia's relevance in the clinical phenotype of PTSD.

Sleep problems in adolescents with depression: Role of childhood trauma, alexithymia, rumination, and self-esteem

BACKGROUND

While sleep problems are common in adolescents with depression, the exact prevalence has not been reported. Although previous studies have shown that childhood trauma, alexithymia, rumination, and self-esteem are related to sleep problems, the interactions between these factors remain unclear.

METHODS

This study, conducted from March 1, 2021 to January 20, 2022, employed a cross-sectional design. The participants were 2192 adolescents with depression with a mean age of 15 years. The Chinese version of the Pittsburgh Sleep Quality Index, Childhood Trauma Questionnaire, Toronto Alexithymia Scale-20, Ruminative Response Scale, and Rosenberg Self-Esteem Scale were used to measure sleep problems, childhood trauma, alexithymia, rumination, and self-esteem, respectively. We used PROCESS 3.3 for SPSS to determine the chain mediating effect of alexithymia and rumination and the moderating effect of self-esteem in the relationship between childhood trauma and sleep problems.

RESULTS

Up to 70.71 % of adolescents with depression had sleep problems. Furthermore, alexithymia and rumination played a chain mediation role in the relationship between childhood trauma and sleep problems. Finally, self-esteem moderated the relationships between alexithymia and sleep problems and rumination and sleep problems.

LIMITATIONS

Owing to the study design, we cannot derive causal relationships between variables. Further, the self-reported data may have been influenced by subjective participant factors.

CONCLUSIONS

This study reveals potential ways of how childhood trauma influences sleep problems in adolescents with depression. These findings suggest that interventions targeting alexithymia, rumination, and self-esteem in adolescents with depression may be effective in reducing their sleep problems.

Longitudinal Investigation of Bidirectional Relations Between Childhood Trauma and Emotion-Driven Impulsivity in the Adolescent Brain Cognitive Development Study

OBJECTIVE

Exposure to childhood trauma is associated with numerous adverse mental health consequences. Addressing important gaps in the existing research, the proposed study clarifies the longitudinal and bidirectional associations between childhood trauma and both negative and positive emotion-driven impulsivity.

METHOD

This study utilized a sample of 11,872 9- to 10-years-olds recruited from 21 research sites across the United States from the Adolescent Brain Cognitive Ddevelopment (ABCD) Study. Childhood trauma was assessed at one- and two-year follow-ups. Negative and positive urgency were assessed at baseline and two-year follow-up. Cross-lagged panel models evaluated the longitudinal and bidirectional associations between childhood trauma and both negative and positive emotion-driven impulsivity.

RESULTS

Findings showed that earlier childhood trauma was associated with higher levels of later negative (β = 0.133, p < .001) and positive (β = 0.125, p < .001) emotion-driven impulsivity. Further, higher levels of earlier positive (β = 0.033, p < .006), but not negative (β = 0.010, p = .405), emotion-driven impulsivity were associated with later childhood trauma. Finally, the strength of the relations between childhood trauma and emotion-driven impulsivity did not differ by sex (ΔX2 = 10.228, p > .05).

DISCUSSION

Identification of both negative and positive emotion-driven impulsivity among children exposed to trauma may serve as a point of intervention to reduce subsequent risk for deleterious health outcomes.

Attachment and alexithymia predict emotional-behavioural problems of institutionalized, late-adopted and community adolescents: An explorative multi-informant mixed-method study

OBJECTIVE

Compared to community adolescents (COM), adolescents placed in residential care (RC) or late adopted (LA) appear to show more emotional-behavioural problems. They also appear vulnerable in variables linked to emotional-behavioural problems, such as insecure-disorganized attachment and alexithymia. This study employs a mixed-method multi-informant approach to (1) compare adolescents placed in RC, LA and COM in emotional-behavioural problems, attachment and alexithymia and (2) investigate relationships and interplay of attachment and alexithymia concerning emotional-behavioural problems in these three groups.

METHOD

Participants were 174 adolescents (50 RC, 33 LA and 91 COM; Mage  = 15, 53% boys and 47% girls). Adolescents' internalizing and externalizing problems were assessed through both caregiver-reported and self-reported questionnaires, while attachment and alexithymia were assessed with a mixed method, using interviews and self-report questionnaires.

RESULTS

The results showed RC adolescents as more vulnerable in all variables, while LA and COM did not differ. Accounting for the group, attachment and alexithymia cumulatively predicted 25-43% of internalizing problems, and 19-43% of externalizing problems depending on the method of assessment or problems' informant (all p < 0.01). Alexithymia was both an independent predictor and interacted with preoccupied attachment in predicting internalizing problems, while no predictors were isolated for externalizing ones, and the group never indicate an effect on problems' rates.

CONCLUSIONS

The authors discuss the utility to maintain a research focus on attachment and alexithymia, also suggesting future directions of research. A need to determine potential distortions of results because of problems' informant and method of assessment is also highlighted.

A lived experience response to the proposed diagnosis of terminal anorexia nervosa: learning from iatrogenic harm, ambivalence and enduring hope

The ethical approach to treatment non-response and treatment refusal in severe-enduring anorexia nervosa (SE-AN) is the source of significant ethical debate, particularly given the risk of death by suicide or medical complications. A recent article proposed criteria to define when anorexia nervosa (AN) can be diagnosed as 'terminal' in order to facilitate euthanasia or physician-assisted suicide (EAS), otherwise known as medical assistance in dying, for individuals who wish to be relieved of suffering and accept treatment as 'futile'. This author utilises their personal lived experience to reflect on the issues raised, including: treatment refusal, iatrogenic harm, suicidality and desire to end suffering, impact of diagnosis/prognosis, schemas, alexithymia, countertransference, ambivalence, and holding on to hope. Within debates as critical as the bioethics of involuntary treatment, end-of-life and EAS in eating disorders, it is crucial that the literature includes multiple cases and perspectives of individuals with SE-AN that represent a wide range of experiences and explores the complexity of enduring AN illness, complex beliefs, communication patterns and relational dynamics that occur in SE-AN.

Assessing autism spectrum disorder in children with a background of maltreatment: challenges and guidance

There may be some similarities in the presentation of children who have autism spectrum disorder (ASD) and those exposed to maltreatment affecting assessment and diagnosis. Overlapping characteristics include difficulties understanding and maintaining relationships, sensitivity to routine and hyper-reactivity to sensory inputs. Children who have been maltreated are at increased risk of various developmental vulnerabilities with both environmental and genetic factors being relevant. The existing epidemiological evidence has found that looked-after children are more likely to screen positively for neurodevelopmental disorders and there are smaller scale studies in adoptive children finding higher rates of ASD than would be expected in the general population. Other research suggests a predominantly genetic basis for this increased risk in keeping with what is generally understood about the aetiology of autism. Children exposed to profound deprivation in Romanian orphanages were found to be at higher risk of a pattern of traits termed 'quasi autistic' which tended to reduce following adoption, but these findings have not been replicated in children experiencing maltreatment in birth families. Reactive attachment disorder (RAD) has some overlapping criteria with ASD, but its prevalence is unknown and children with RAD should be more socially reciprocal and not have the same repetitive and restricted behaviours and interests. We recommend experienced multidisciplinary assessment that considers both the possibility of maltreatment in children with ASD and neurodevelopmental vulnerabilities in children who have been maltreated and advise on assessment and management strategies.

Mechanisms by which adverse childhood experiences, other traumas and PTSD influence the health and well-being of individuals with eating disorders throughout the life span

BACKGROUND

Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality.

METHODS

In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable.

RESULTS

At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide.

CONCLUSIONS

The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

Difficulties in facial emotion recognition: taking psychopathic and alexithymic traits into account

BACKGROUND

Alexithymic and psychopathic traits are closely associated, but distinct constructs. Both have been associated with facial emotion processing deficits reflecting empathy deficits, however the underlying mechanism contributing to these deficits is not well-understood.

METHODS

This study investigated facial emotion recognition performance in a non-clinical sample (N = 110) including both male and female participants, with varying levels of psychopathic and alexithymic traits. Facial emotion recognition was assessed using a computerized task, that presented different expressions depicting five emotional states (pain, fear, sadness, anger, happiness) and neutral expressions.

RESULTS

Results suggest that the high psychopathic traits group reported lower accuracy compared to the low psychopathic traits group, indicating a more generalized deficit in facial affect recognition, across all emotions. The alexithymic groups (high vs. low) on the other hand did not differ in their performance on the task for any of the emotions presented.

CONCLUSION

These findings add to the current body of research regarding face processing categorization deficits in relation to psychopathic and alexithymic traits and can inform prevention and intervention efforts that aim to facilitate facial emotion recognition in individuals with these personality traits.
