Psychoanalysis and empirical research: the example of alexithymia

The relationship between social withdrawal and problematic social media use in Chinese college students: a chain mediation of alexithymia and negative body image

This study explores the relationship between social withdrawal and problematic social media use among college students, with a focus on the mediating roles of alexithymia and negative body image. Using the University Student Social Withdrawal Questionnaire, Social Media Addiction Scale, Toronto Alexithymia Scale, and Negative Body Image Scale, 2582 college students (33.46% male, average age = 19.46 years, SD = 2.23) were surveyed. Social withdrawal, alexithymia, negative body image, and problematic social media use were significantly correlated with each other. Social withdrawal positively predicted problematic social media use, and both alexithymia and negative body image played a chain mediating role between social withdrawal and problematic social media use. The findings indicate that individual social withdrawal is associated with college students' problematic use of social media. The results suggest that alexithymia and negative body image may mediate this association, highlighting a potential pathway through which social withdrawal influences social media use patterns.

Introversion, Alexithymia, and Hostility: A Path Analysis From Personality to Suicidal Ideation Among University Students

PURPOSE

The aim of the current study was to investigate the relationship between state (i.e., hostility) and trait (i.e., social detachment, alexithymia) psychological constructs associated with suicidal ideation among university students.

METHODS

A group of 190 university students was consecutively recruited in the period between September 2022 and March 2023. After a clinical interview, a series of psychological tests were administered: the Cattell's 16-Personality Factors Questionnaire (16PF), the Toronto Alexithymia Scale (TAS-20), the Symptom Checklist-90-R (SCL-90-R), and the anamnestic form of the Cognitive Behavioral Assessment (CBA2.0), which contains a specific question regarding the suicidal ideation.

RESULTS

The analyses demonstrated that alexithymia fully mediated the relationship between a particular aspect of introversion (social detachment or low warmth) and hostility which, in turn, seemed to be a significant predictor of suicidal ideation.

CONCLUSIONS

The path analysis conducted seemed to highlight the importance of personality traits, such as social detachment and the ability to recognize and express one's internal states, on the mental health of university students in terms of hostility and suicidal ideation. Considering that the reduction of suicide mortality has been prioritized as a global target in the 15-19 age group, identifying the psychological factors associated with it is fundamental.

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.

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.

Examining the Incremental Validity of the Perth Alexithymia Questionnaire (PAQ) Relative to the 20-Item Toronto Alexithymia Scale (TAS-20)

The 20-item Toronto Alexithymia Scale (TAS-20) is the most widely used instrument for assessing alexithymia, with more than 25 years of research supporting its reliability and validity. The items that compose this scale were written to operationalize the components of the construct that are based on clinical observations of patients and thought to reflect deficits in the cognitive processing of emotions. The Perth Alexithymia Questionnaire (PAQ) is a recently introduced measure and is based on a theoretical attention-appraisal model of alexithymia. An important step with any newly developed measure is to evaluate whether it demonstrates incremental validity over existing measures. In this study using a community sample (N = 759), a series of hierarchical regression analyses were conducted that included an array of measures assessing constructs closely associated with alexithymia. Overall, the TAS-20 showed strong associations with these various constructs to which the PAQ was unable to add any meaningful increase in prediction relative to the TAS-20. We conclude that until future studies with clinical samples using several different criterion variables demonstrate incremental validity of the PAQ, the TAS-20 should remain the self-report measure of choice for clinicians and researchers assessing alexithymia, albeit as part of a multi-method approach.

Alexithymia modulates emotion concept activation during facial expression processing

Alexithymia is characterized by difficulties in emotional information processing. However, the underlying reasons for emotional processing deficits in alexithymia are not fully understood. The present study aimed to investigate the mechanism underlying emotional deficits in alexithymia. Using the Toronto Alexithymia Scale-20, we recruited college students with high alexithymia (n = 24) or low alexithymia (n = 24) in this study. Participants judged the emotional consistency of facial expressions and contextual sentences while recording their event-related potentials. Behaviorally, the high alexithymia group showed longer response times versus the low alexithymia group in processing facial expressions. The event-related potential results showed that the high alexithymia group had more negative-going N400 amplitudes compared with the low alexithymia group in the incongruent condition. More negative N400 amplitudes are also associated with slower responses to facial expressions. Furthermore, machine learning analyses based on N400 amplitudes could distinguish the high alexithymia group from the low alexithymia group in the incongruent condition. Overall, these findings suggest worse facial emotion perception for the high alexithymia group, potentially due to difficulty in spontaneously activating emotion concepts. Our findings have important implications for the affective science and clinical intervention of alexithymia-related affective disorders.

Addressing psychosomatic symptom distress with mindfulness-based cognitive therapy in somatic symptom disorder: mediating effects of self-compassion and alexithymia

Objective

This study explored the association between self-compassion, alexithymia, and psychosomatic symptom distress in a clinical sample of somatic symptom disorder (SSD) patients participating in a mindfulness-based cognitive therapy (MBCT) program.

Methods

One hundred sixteen SSD patients who had participated in an MBCT program and completed ≥4 intervention sessions were included in a retrospective study (76.7% women, mean age = 40.0, SD = 9.5). Psychometric measures of psychosomatic symptom distress [Brief Symptom Inventory-18 Global Severity Index (BSI-GSI)], self-compassion [Self-Compassion Scale (SCS)], and alexithymia [Toronto Alexithymia Scale (TAS)] were collected upon admission to the MBCT program and at 6-month follow-up following treatment inclusion.

Results

Serial mediation analysis (MBCT→ΔSCS→ΔTAS→ΔBSI-GSI) suggested that changes in both self-compassion and alexithymia had significant indirect effects on improvement in psychosomatic distress [ΔSCS β = -1.810, 95% bootstrap CI (-2.488, -1.160); ΔTAS β = -1.615, bootstrap 95% CI (-2.413, -0.896); ΔSCS→ΔTAS β = -0.621, bootstrap CI (-1.032, -0.315)]. Furthermore, a post-hoc analysis with a reverse sequence (MBCT→ΔTAS→ΔSCS→ΔBSI-GSI) revealed that reduction in alexithymia improved psychosomatic distress and that an increase in self-compassion was a subsequent outcome of alleviation of alexithymia [ΔTAS β = -2.235, bootstrap 95% CI (-3.305, -1.270); ΔSCS β = 0.013, 95% bootstrap CI (-0.600, 0.682); ΔTAS→ΔSCS β = -1.823, bootstrap CI (-2.770, -1.047)].

Conclusion

Both alleviation of alexithymia and improvement in self-compassion play a mediating role in the reduction of psychosomatic distress in SSD patients following an MBCT program. Improvement in self-compassion might be a subsequent outcome of MBCT-related alleviation of alexithymia.

Role of Alexithymia in the Association Between Childhood Abuse and Risk Perception for Sexual Victimization in College Women

Sexual victimization is prevalent among college women with a history of childhood abuse (CA), which some research suggests is linked to impaired risk perception for sexual victimization or difficulties identifying and responding to unwanted sexual advances. Alexithymia is one construct yet to be examined in the association between CA and risk perception for sexual victimization. The purpose of this study was to elucidate the associations between CA, alexithymia, and risk perception for sexual victimization in a sample of college women with a history of CA. Participants included 294 undergraduate women with a history of childhood emotional, physical, and/or sexual abuse (Mage = 20.6, 80.6% White). An a priori path analysis was conducted to examine whether alexithymia indirectly explains the association between CA and risk perception for sexual victimization (i.e., comprising two related constructs, including threat detection and behavioral response to threat). Supplementary analyses were conducted post hoc to examine potential differences across CA subtypes (emotional, physical, and sexual). Alexithymia indirectly explained the relationship between CA and threat detection, and behavioral response to threat. However, indirect effects were negative, suggesting that undergraduate women with more severe CA and alexithymia identify sexual assault threat cues and intentions to "leave" a hypothetical sexual assault scenario sooner rather than later. The same pattern of results was observed for emotional and physical (but not sexual) CA when examining their indirect effects on threat detection, and for emotional CA when examining behavioral response to threat. Findings contribute to the literature on sexual victimization by clarifying the role of alexithymia in risk perception for sexual victimization. Results also highlight the potential utility of increasing emotional literacy among college women with a history of CA (and especially emotional abuse) to facilitate adaptive responding to unwanted sexual advances.

Type 1 Diabetes Mellitus, Psychopathology, Uncertainty and Alexithymia: A Clinical and Differential Exploratory Study

Type 1 diabetes mellitus (T1DM) represents a complex pathology affecting a large number of people. Research suggests that psychological factors influence coping with T1DM. This study aimed to investigate the presence and role of psychopathology, alexithymia and uncertainty in people affected by T1DM. The sample consisted of 137 patients (88 females, 49 males) affected by T1DM aged from 11 to 19 years old (Mean: 13.87; SD: 2.40). The diagnostic protocol consisted of a sociodemographic questionnaire, Self-administration Psychiatric Scales for Children and Adolescents (SAFA), Toronto Alexithymia Scale-20 (TAS-20) and Intolerance to Uncertainty Scale-12 (IUS-12). Descriptive, differential, correlational and regression analyses were performed in order to examine the relationships between these variables. The results suggested the sample had high levels of psychopathological indexes, alexithymia and intolerance of uncertainty. Also, there were significant differences between TAS-20 and IUS-12 distributions with respect to psychopathology. Correlations and multivariate linear regressions indicated age, gender and education significantly predicted alexithymia and intolerance of uncertainty. This data suggest the presence of elevated psychopathology, alexithymia and uncertainty in people with diabetes.

Moderating effect of alexithymia between problem gambling and psychotic experiences in university students

BACKGROUND

Most of the young individuals with problem gambling (PG) or psychotic experiences (PEs) are less prone to seek medical help. Therefore, community-based studies investigating the relationship between these entities in non-clinical young people across a continuum of severity are warranted. To this end, the present study proposes to advance knowledge on the mechanisms that potentially underlie the association between PG and PEs, by examining the role of a potential moderator, i.e. alexithymia, in this relationship.

METHODS

A total of 399 participants enrolled in this study (mean age = 21.58 ± 3.20 years) participated in an online cross-sectional survey. The South Oaks Gambling Screen (SOGS), the Prodromal Questionnaire-Brief (PQ-B), and the Toronto alexithymia scale (TAS-20) were used.

RESULTS

Thirty-three (8.3%) participants had problem-gambling, whereas 13 (3.3%) were probable pathological gamblers. Moderation analysis results adjusted over confounders (age, household crowding index, marital status, personal history of mental disorder, other illegal drug use) showed that the interaction PG by alexithymia (p = .018) was significantly associated with PEs scores. At moderate (Beta = 1.93) and high (Beta = 3.38) levels of alexithymia, more PG was significantly associated with more PEs scores.

CONCLUSION

Findings suggest that GP may have a different impact on PEs depending on the individual's level of alexithymia. As such, both alexithymia and gambling behavior should be considered in the clinical assessment of young people who present with PEs, which can help in implementing more tailored and individualized treatment plans.

Social cognition in hyperkinetic movement disorders: a systematic review

Numerous lines of research indicate that our social brain involves a network of cortical and subcortical brain regions that are responsible for sensing and controlling body movements. However, it remains unclear whether movement disorders have a systematic impact on social cognition. To address this question, we conducted a systematic review examining the influence of hyperkinetic movement disorders (including Huntington disease, Tourette syndrome, dystonia, and essential tremor) on social cognition. Following the PRISMA guidelines and registering the protocol in the PROSPERO database (CRD42022327459), we analyzed 50 published studies focusing on theory of mind (ToM), social perception, and empathy. The results from these studies provide evidence of impairments in ToM and social perception in all hyperkinetic movement disorders, particularly during the recognition of negative emotions. Additionally, individuals with Huntington's Disease and Tourette syndrome exhibit empathy disorders. These findings support the functional role of subcortical structures (such as the basal ganglia and cerebellum), which are primarily responsible for movement disorders, in deficits related to social cognition.

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.

Women's Narratives on Infertility as a Traumatic Event: An Exploration of Emotional Processing through the Referential Activity Linguistic Program

BACKGROUND

the diagnosis of infertility and its related treatment can be traumatic, leading to profound psychological distress and a variety of psychopathological symptoms. The primary objective of this study is to contrast the linguistic features of narratives from women undergoing Assisted Reproductive Treatment with those of women not undergoing any fertility treatment. This study examines the speech of both groups of individuals as an indicator of their capacity to cope with current and past distressing experiences.

METHOD

44 women (mean age 36.05; SD = 4.66) enrolled in a fertility medical center in Rome, and 43 control women (mean age 36.07; SD = 3.47) completed a socio-demographic questionnaire and a semi-structured interview designed to collect their memories of a neutral, a positive, and a negative event. This interview also aimed to investigate: (a) (for women with fertility difficulties) how they realized they and their partner had fertility problems and a description of an event when they talked about these difficulties with their partner; and (b) (for control group participants) the most difficult moment of their pregnancy and an event when they talked about it with their partner. The interviews were audio recorded and transcribed, and the text was analyzed using the referential process (RP) linguistic measures software.

RESULTS

Mann-Whitney non-parametric U tests for the independent samples showed several significant differences regarding the linguistic measures applied to the narratives of neutral, positive, negative, and difficult experiences in the form of a linguistic style, with more intellectualization and defenses in all the narratives associated with the women with fertility problems compared to the women in the control group.

CONCLUSIONS

the traumatic and painful experience of infertility and ART seems to characterize the whole mode of narrating life experiences. Present findings sustain the importance of helping women to elaborate on their experience and to understand and recognize the difficult feelings that are activated in relation to the difficulties of having a child.

Self-disgust in patients with borderline personality disorder. The associations with alexithymia, emotion dysregulation, and comorbid psychopathology

BACKGROUND

Self-disgust is a negative self-conscious emotion, which has been linked with borderline personality disorder (BPD). However, it has not yet been investigated in relation to both emotion dysregulation and alexithymia, which are recognized as crucial to BPD. Therefore, the aim of our study was to measure these variables and examine the possible mediational role of emotional alterations and comorbid anxiety and depression symptoms in shaping self-disgust in patients with BPD and healthy controls (HCs).

METHODS

In total, the study included 100 inpatients with BPD and 104 HCs. Participants completed: the Self-Disgust Scale (SDS), Disgust Scale - Revised (DS-R), Toronto Alexithymia Scale (TAS-20), Emotion Dysregulation Scale short version (EDS-short), Borderline Personality Disorder Checklist (BPD Checklist), State-Trait Anxiety Inventory (STAI), and Center for Epidemiologic Studies Depression Scale (CESD-R).

RESULTS

Inpatients with BPD showed higher self-disgust, alexithymia, emotion dysregulation, core and comorbid symptoms levels, and lower disgust sensitivity. Alexithymia, emotion dysregulation, and trait anxiety partially mediated between BPD diagnosis and self-disgust. The relationship between the severity of BPD symptoms and self-disgust was fully mediated by alexithymia, emotion dysregulation, depressive symptoms, and trait anxiety.

CONCLUSIONS

The results of our study may imply the contribution of emotion dysregulation, alexithymia, and comorbid psychopathology to self-referenced disgust in BPD.

Effects of Alexithymia on Moral Decision-Making in Sacrificial Dilemmas: High Alexithymia is Associated with Weaker Sensitivity to Moral Norms

Purpose

Although several studies have investigated the association between alexithymia and moral decision-making in sacrificial dilemmas, the evidence remains mixed. The current work investigated this association and how alexithymia affects moral choice in such dilemmas.

Methods

The current research used a multinomial model (ie, CNI model) to disentangle (a) sensitivity to consequences, (b) sensitivity to moral norms, and (c) general preference for inaction versus action irrespective of consequences and norms in responses to moral dilemmas.

Results

Higher levels of alexithymia were associated with a greater preference for utilitarian judgments in sacrificial dilemmas (Study 1). Furthermore, individuals with high alexithymia showed significantly weaker sensitivity to moral norms than did those with low alexithymia, whereas there were no significant differences in sensitivity to consequences or a general preference for inaction versus action (Study 2).

Conclusion

The findings suggest that alexithymia affects moral choice in sacrificial dilemmas by blunting emotional reactions to causing harm, rather than through increased deliberative cost-benefit reasoning or general preference for inaction.

Relationship between alexithymia, loneliness, resilience and non-suicidal self-injury in adolescents with depression: a multi-center study

OBJECTIVE

Non-suicidal self-injury (NSSI) behaviors are prevalent in adolescents and have adverse effects on physical and mental health. However, little is known about the relationship between NSSI and alexithymia, or the underlying mechanisms that could explain this relationship. This study aimed to elucidate the current status of NSSI in adolescent depression, and analyze the relationship between alexithymia, loneliness, resilience, and adolescent depression with NSSI, so as to provide a theoretical basis for psychotherapeutic interventions.

METHOD

The study sample involved inpatients and outpatients from 12 hospitals across China and adolescents with depression who met the DSM-5 diagnostic criteria for depression episode. The following scales were used: The Functional Assessment of Self-Mutilation, Toronto Alexithymia Scale, UCLA Loneliness Scale, and Connor Davidson Resilience Scale.

RESULTS

The detection rate of NSSI in adolescents with depression from 2021.01.01-2022.01.01 was 76.06% (1782/2343). Spearman's correlation analysis revealed a significant correlation between alexithymia, loneliness, resilience and NSSI in depressed adolescents, and the results of the non-parametric test showed that the differences between the two groups for each factor were statistically significant. Binary logistic regression results showed that alexithymia (B = 0.023, p = 0.003, OR = 1.023, 95% CI: 1.008-1.038) and depression (B = 0.045, p < 0.001, OR = 1.046, 95% CI: 1.026-1.066) are risk factors for NSSI, resilience (B = - 0.052, p < 0.001, OR = 0.949, 95% CI: 0.935 - 0.964) is a protective factor for NSSI. Alexithymia directly predicted NSSI and also indirectly influenced NSSI through the mediated effect of resilience. Loneliness moderates the first half of the path of this mediated model.

CONCLUSION

The present study confirms a moderated mediation effect: Alexithymia can have an impact on NSSI behaviors in depressed adolescents through the mediating role of resilience. Loneliness, as a moderating variable, moderated the first half of the pathway of the mediating model. We discuss perspectives for future research and interventions based on the findings of the study.

Assisted Reproductive Treatments, Quality of Life, and Alexithymia in Couples

Infertility and related treatments can negatively affect a couple's wellbeing. The aim of this study was to evaluate couples starting assisted reproductive treatment, differences in alexithymia and quality of life levels between partners, and the association of these psychological dimensions within the couple's members. Data was collected in two fertility centres in Rome; 47 couples completed the Fertility Quality of Life (FertiQoL), the 20-item Toronto Alexithymia Scale (TAS-20), and a socio-demographic questionnaire. Data analysis showed a worsened quality of life in women compared with their partners, as well as higher externally oriented thinking in men compared with their spouses. Associations between alexithymia and quality of life levels between women and men emerged. According to the regression analysis, a better quality of life in women was predicted by a greater partner's capabilities in identifying and describing emotion as well as by a better partner's quality of life, whereas for men, a better quality of life was predicted by their spouse's higher levels of quality of life. This study highlights the protective role that couples can play in the perception of the negative impact that infertility can have on their partner's quality of life. Further investigations are needed for the development of specific therapeutic interventions for the promotion of the couples' wellbeing.

Improvement in binge eating and alexithymia predicts weight loss at 9-month follow-up of the lifestyle modification program

PURPOSE

The aim of this longitudinal study was to examine the extent to which improved levels of binge eating (BE) behaviors, alexithymia, self-esteem, and psychological distress would predict a reduction in body mass at 9-month follow-up, following a lifestyle modification program for weight loss in obese or overweight patients.

METHODS

A convenience sample of 120 obese or overweight patients were recruited. Body mass index (BMI), binge eating (BES), levels of alexithymia (TAS-20), perceived stress (PSS), depressive symptoms (SDS), and self-esteem (RSE) were assessed during their first medical examination (T1), and after a weight-loss treatment period of 9 months (T2).

RESULTS

Compared with unimproved patients, improved patients reported a significant decrease in binge eating (p = 0.04) and perceived stress symptoms (p = 0.03), and a significant improvement in self-esteem (p = 0.02) over time. After controlling for gender, self-esteem, depressive symptoms, and perceived stress, baseline BMI (OR = 1.11, 95% CI  [1.04,1.19]), ΔBES (OR = 0.99, 95% CI  [0.98,0.99]), and ΔTAS-20 (OR = 1.03, 95% CI  [1.01,1.05]) significantly and independently predicted a ≥ 5% reduction in body mass from baseline.

CONCLUSIONS

Our finding supports the suggestion to consider psychological outcomes such as emotional aspects and dysfunctional eating behaviors when planning a weight loss programs to prevent a negative outcome.

Effects of DBT-based interventions on alexithymia: a systematic review

While dialectical behavior therapy (DBT) appears effective for some psychiatric conditions commonly associated with alexithymia, it is unclear whether DBT improves difficulties experienced by alexithymic individuals. This review investigated the current evidence on the effectiveness of DBT-based interventions in improving alexithymia. A qualitative synthesis of studies that investigated the efficacy of DBT on self-reported alexithymia was performed, identifying eligible studies using EBSCO/Essentials, Google Scholar, PubMed, Web of Science, and PsychINFO databases. Eight studies were identified. Overall, the results were inconclusive due to the heterogeneity of the studies but suggest that DBT-based interventions may be associated with self-reported decreases in alexithymia and increases in the ability to identify emotional states. The literature is limited by significant methodological problems, such as the low number of controlled trials, small samples, and high variability between DBT programs, which increases the risk of bias across study outcomes. More research is needed to reach conclusions regarding the effectiveness of DBT in improving alexithymia. Future studies should conduct randomized controlled trial designs (primarily with active treatment control conditions), greater standardization of DBT-based interventions, and a more in-depth examination of the level of participant involvement in long-term DBT-based interventions may help to understand whether DBT improves alexithymia difficulties.

Emotional dysregulation and linguistic patterns as a defining feature of patients in the acute phase of anorexia nervosa

PURPOSE

This research aims to analyze the relationship between emotional regulation and the symbolic process in autobiographical narratives of a group of individuals diagnosed with restrictive anorexia nervosa (AN), compared to a non-clinical group. The study is framed within multiple code theory (MCT) (Bucci, 1997; 2021), which considers mind-body integration. The purposes of this study are to investigate whether participants of the AN group will show greater alexithymia and emotional dysregulation than the non-clinical group; and whether the specific linguistic and symbolic features, such as somato-sensory words, affect words, and difficulty in the symbolizing process will predict the AN group.

METHODS

Twenty-nine female participants hospitalized with AN during an acute phase (mean age 19.8 ± 4.1) and 36 non-clinical female participants (mean age 21 ± 2.4) were selected through snow-ball sampling. The participants completed the Toronto Alexithymia Scale (TAS-20), the Profile of Mood of State (POMS), the Emotion Regulation Questionnaire (ERQ), and the Relationship Anecdotes Paradigm Interview (RAP). The RAP interview was audio-recorded and transcribed to apply the Referential Process (RP) Linguistic Measures. A T test for paired samples and a logistic binary regression was performed.

RESULTS

AN presented a significantly higher emotional dysregulation through the ERQ, TAS20 and POMS measures. Specifically, AN showed higher ER expression/suppression strategies, fewer functional cognitive strategies, higher alexithymia, and higher mood dysregulation. Specific linguistic features such as sensory-somatic, word affect, and difficulty in RP symbolizing predict the AN group (R2 = 0.349; χ2 = 27,929; df = 3; p = .001).

CONCLUSIONS

Emotional dysregulation is connected to AN symptoms and autobiographical narratives. The results can help a clinical assessment phase showing specific linguistic features in AN patients.

Alexithymia Among People Living with HIV: A Scoping Review

The present scoping review aimed to identify studies that investigated alexithymia, defined as a difficulty in identifying and describing one's own emotions, in people living with HIV (PLWH).A literature search, in line with the guidelines of PRISMA-ScR, was conducted in the following bibliographic databases: PubMed, PsycINFO, and Web of Science. The databases were queried using the following strings (using Boolean operators): ("alexithymia" OR "alexithymic") AND ("HIV" OR "Human Immunodeficiency Virus"). In line with the eligibility criteria, fourteen articles were found.Ten studies showed the involvement of alexithymia in disease severity (e.g., viral load levels), and adherence to antiretroviral therapy. Three studies revealed an association between alexithymia and cardiovascular disease, and three studies highlighted the implication of alexithymia in cognitive impairment.This review revealed the complex role of alexithymia in HIV disease. A careful clinical assessment of the emotional regulation process of PLWH can provide useful prognostic information.

A cross-modal component of alexithymia and its relationship with performance in a social cognition task battery

BACKGROUND

The personality trait alexithymia describes an altered emotional awareness that is associated with a range of social impairments and constitutes a transdiagnostic risk factor for various psychopathologies. Despite the characteristic interoceptive deficits in alexithymia, it is predominantly assessed via self-reports. This can result in unreliable measurements and arguably contributes to the prevailing uncertainty regarding its components, including constricted imaginal processes and emotional reactivity.

METHODS

The current study employed an interview and two validated questionnaires to derive a shared component of multi-modally assessed alexithymia in a German non-clinical sample (n = 78) via prinicipal component analysis. This component was used as a predictor for performance in four behavioural social cognition tasks. The relative importance of this predictor against related variables was assessed via dominance analysis.

RESULTS

The identified component reflected cognitive alexithymia. Higher cognitive alexithymia scores were associated with less affective distress in an ostracizing task. Dominance analysis revealed the dominance of competing autism traits relative to cognitive alexithymia and competing predictors empathy, depression, and anxiety, in predicting affective distress.

LIMITATIONS

Emotional reactivity was only assessed via self-report and no implicit measures of alexithymia were employed. Due to the low reliability of the self-report measure, no measure of emotional reactivity could be included in the principal component analysis.

CONCLUSIONS

Our results provide compelling evidence that cognitive interoceptive deficits are at the core of alexithymia across assessment modalities. Behavioural data suggest that these deficits result in diminished emotional sensitivity to high-pressure social situations, which may cause a lack of behavioural adaptation.

Functional (psychogenic non-epileptic/dissociative) seizures: why and how?

Functional seizures (FS) known also as psychogenic non-epileptic seizures or dissociative seizures, present with ictal semiological manifestations, along with various comorbid neurological and psychological disorders. Terminology inconsistencies and discrepancies in nomenclatures of FS may reflect limitations in understanding the neuropsychiatric intricacies of this disorder. Psychological and neurobiological processes of FS are incompletely understood. Nevertheless, important advances have been made on underlying neuropsychopathophysiological mechanisms of FS. These advances provide valuable information about the underlying mechanisms of mind-body interactions. From this perspective, this narrative review summarises recent studies about aetiopathogenesis of FS at two levels: possible risk factors (why) and different aetiopathogenic models of FS (how). We divided possible risk factors for FS into three categories, namely neurobiological, psychological and cognitive risk factors. We also presented different models of FS based on psychological and neuroanatomical understanding, multilevel models and integrative understanding of FS. This work should help professionals to better understand current views on the multifactorial mechanisms involved in the development of FS. Shedding light on the different FS profiles in terms of aetiopathogenesis will help guide how best to direct therapy, based on these different underlying mechanisms.

Psychometric evaluation of the Norwegian Toronto Alexithymia Scale (TAS-20) in a multisite clinical sample of patients with personality disorders and personality problems

OBJECTIVE

Psychometric properties of 20-item Toronto Alexithymia Scale (TAS-20) have been widely analyzed, but the validity and psychometric qualities of the TAS-20 in populations with personality disorders are still poorly understood. The aim of the current study was to analyze the factor structure and validity of TAS-20.

METHOD

Data were extracted from a multisite clinical sample of patients with personality disorders or personality-related problems referred to specialist mental health services in Norway.

RESULTS

With one exception, TAS-20 revealed acceptable psychometric properties. Variations of TAS-20 are associated with other clinical measures of distress and severity. Anxiety disorders, borderline, and avoidant personality disorders were all highly related to levels of TAS-20. The TAS-20 also revealed unique variance not accounted for by subjective distress, symptom disorders, or dysfunctional personality traits.

CONCLUSION

The TAS-20 is a relevant instrument for use in assessment of personality disorders, but one subscale should be improved.

Alexithymia, social support, depression, and burnout among emergency nurses in China: a structural equation model analysis

Background

Several factors are associated with the incidence of burnout, including alexithymia, social support, and depression. The relative importance of these three key parameters as mediators of burnout, however, is not well understood. In addition, there have been few studies to date specifically examining the association between alexithymia and burnout among nurses in China.

Purpose

To evaluate the relationship of burnout with alexithymia, social support, and depression across emergency department nurses in China.

Methods

This descriptive, cross-sectional survey was conducted using a convenience sampling methodology to survey nurses responsible for direct emergency care (n = 413) from 18 tertiary hospitals in Western, Eastern, Northern, and Southern China between May 2020 and June 2020. A structural equation modeling approach was then used to assess a hypothetical model wherein alexithymia both directly and indirectly affects burnout among emergency nurses via impacting the incidence of depression and perceived social support.

Results

Results supported all driving hypotheses. Alexithymia was positive direct correlated with burnout (β = 0.35; P < 0.001) and depression (β = 0.50; P < 0.001), and exhibited a negative direct effect on social support (β = − 0.14; P = 0.041). Depression was associated with burnout, both directly (β = 0.24; P < 0.001) and indirectly (β = 0.15; P < 0.001) through its relationship with social support. Alexithymia was the factor most strongly associated with burnout, and it was able to affect burnout indirectly through depression and social support.

Conclusions

We found that among emergency nurses in China, alexithymia was correlated with burnout, depression, and social support. Alexithymia was the factor most strongly associated with burnout. These data suggest that providing better social support and alleviating alexithymia may decrease rates of burnout among emergency nurses.

Alexithymia and Facial Mimicry in Response to Infant and Adult Affect-Expressive Faces

Facial mimicry is the automatic tendency to imitate facial expressions of emotions. Alexithymia is associated with a reduced facial mimicry ability to affect expressions of adults. There is evidence that the baby schema may influence this process. In this study it was tested experimentally whether facial mimicry of the alexithymic group (AG) is different from the control group (CG) in response to dynamic facial affect expressions of children and adults. A multi-method approach (20-point Toronto Alexithymia Scale and Toronto Structured Interview for Alexithymia) was used for assessing levels of alexithymia. From 3503 initial data sets, two groups of 38 high and low alexithymic individuals without relevant mental or physical diseases were matched regarding age, gender, and education. Facial mimicry was induced by presentation of naturalistic affect-expressive video sequences (fear, sadness, disgust, anger, and joy) taken from validated sets of faces from adults (Averaged Karolinska Directed Emotional Faces) and children (Picture-Set of Young Children's Affective Facial Expressions). The videos started with a neutral face and reached maximum affect expression within 2 s. The responses of the groups were measured by facial electromyographic activity (fEMG) of corrugator supercilii and zygomaticus major muscles. Differences in fEMG response (4000 ms) were tested in a variance analytical model. There was one significant main effect for the factor emotion and four interaction effects for the factors group × age, muscle × age, muscle × emotion, and for the triple interaction muscle × age × emotion. The participants of AG showed a decreased fEMG activity in response to the presented faces of adults compared to the CG but not for the faces of children. The affect-expressive faces of children induced enhanced zygomatic and reduced corrugator muscle activity in both groups. Despite existing deficits in the facial mimicry of alexithymic persons, affect-expressive faces of children seem to trigger a stronger positive emotional involvement even in the AG.

Investigating defensive functioning and alexithymia in substance use disorder patients

BACKGROUND

Substance Use Disorder (SUD) causes a great deal of personal suffering for patients. Recent evidence highlights how defenses and emotion regulation may play a crucial part in the onset and development of this disorder. The aim of this study was to investigate potential differences in the defensive functioning between SUD patients and non-clinical controls. Secondly, we aimed at investigating the relationships between alexithymia and maladaptive/assimilation defenses.

METHODS

The authors assessed defensive functioning (Response Evaluation Measure-71, REM-71), personality (MMPI-II), and alexithymia (TAS-20) of 171 SUD patients (17% female; mean age = 36.5), compared to 155 controls. Authors performed a series of ANOVAs to investigate the defensive array in SUD patients compared to that of non-clinical controls. Student t test for indipendent samples was used to compare clinical characteristics between the SUD group and the controls. To investigate the role of single defenses in explaining alexithimia's subscores, stepwise multiple regression analysis were carried out on socio-demographic characteristics of participants (gender, age, and years of education), with REM-71 defenses as predictors.

RESULTS

SUD patients presented a more maladaptive/assimilation (Factor 1) defensive array (p < .001). Among SUD sub-groups, Alcohol Use Disorder patients showed more disfuncional defenses. Factor 1 defenses were related to a worse psychological functioning. In addition, alexyhimia (particularly DIF) was strongly related to Factor 1 defenses, expecially Projection (38% of variance explained, β = .270, p < .001).

CONCLUSION

The REM-71 and the TAS-20 might be useful screening instruments among SUD patients.

The effects of alexithymia, experiential avoidance, and childhood sexual abuse on non-suicidal self-injury and suicidal ideation among Chinese college students with a history of childhood sexual abuse

BACKGROUND

Although previous studies have shown that childhood sexual abuse (CSA) experiences might be related to suicide-related thoughts and behaviours in later life, the effects of alexithymia and experiential avoidance (EA) on this relationship have remained unclear. The present study aimed to expand prior findings among Chinese college students with a history of CSA in order to further test the effects of alexithymia on the relationship between CSA and non-suicidal self-injury (NSSI) and suicidal ideation (SI), and its indirect effects on NSSI and SI through EA.

METHODS

The Childhood Sexual Abuse Questionnaire, the Toronto Alexithymia Scale-20, the Acceptance and Action Questionnaire-II, the Non-Suicidal Self-Injury Questionnaire, and the Symptom Checklist were completed by 6,834 college students (3,829 female).

RESULTS

Overall, 1404 (20.76%) Chinese college students reported experiences of CSA; students with CSA experiences reported higher rates of SI and NSSI than those without CSA (12.82% vs. 4.50%, 35.11% vs. 20.82%). CSA, alexithymia, and EA were positively related to NSSI and SI. The effect of alexithymia on the relationship between CSA and NSSI and SI were significant. The effects of EA on the relationship between alexithymia and NSSI and SI were significant, too.

LIMITATIONS

The major limitations of this study are its cross-sectional design and the use of self-report scales, especially retrospective self-reports (e.g., the Childhood Sexual Abuse Questionnaire).

CONCLUSIONS

This study cast light on the effects of alexithymia, EA, and CSA on NSSI and SI in Chinese college students with a history of CSA. These findings can contribute to the prevention and treatment of suicide-related thoughts and behaviours.

Development and psychometric evaluation of an informant form of the 20-item Toronto alexithymia scale

OBJECTIVE

The alexithymia personality construct encompasses difficulties identifying and describing feelings, restricted imaginal processes, and an externally oriented cognitive style. The construct was derived initially from observations of patients with classic psychosomatic diseases. The self-report 20-item Toronto Alexithymia Scale (TAS-20) is the most frequently used measure to assess alexithymia. A concern associated with the TAS-20 is whether individuals can accurately self-report difficulties identifying and describing feelings if they are deficient in those abilities. To address this issue, we sought to develop and validate an informant form (version) of the TAS-20, the 20-item Toronto Alexithymia Scale - Informant Form (TAS-20-IF).

METHOD

We employed a three-phase methodological strategy. In the first phase, items from the TAS-20 were re-written into a third person version by a team of experts. In the second phase, the "traditional" three-factor structure was tested in the TAS-20-IF using confirmatory factor analysis in a large sample of young adults (N = 857). The third phase was conducted with another sample (N = 430) composed of "informants" (n = 215), who completed the TAS-20-IF, and "targets" (n = 215), who completed the TAS-20 (informants were nominated by the targets).

RESULTS

The psychometric properties (items and scales) of both versions were adequate and the three-factor structure of the TAS-20-IF was supported; the correlation between the two versions was statistically significant and the factor structures were similar.

CONCLUSION

Although further research is needed to replicate these findings, especially in clinical samples, the results support the reliability and validity of the TAS-20-IF.

Prevalence and Correlates of Alexithymia and Its Relationship With Life Events in Chinese Adolescents With Depression During the COVID-19 Pandemic

Objectives: The incidence of psychological and behavioral problems and depression among adolescents is increasing year by year, which has become an important public health problem. Alexithymia, as an important susceptible factor of adolescent depression, may continue to develop and strengthen under the stimulation of COVID-19-related stressors. However, no studies have focused on alexithymia in adolescent depression during the pandemic in China. This study aims to investigate the incidence and related factors of alexithymia in adolescent depression during the pandemic. Methods: Three hundred adolescent patients were enrolled from October 2020 to May 2021. The general demographic information of all participants was collected, and the clinical characteristics were assessed by the 20-item Toronto Alexithymia Scale (TAS-20), the Adolescent Self-Rating Life Events Check (ASLEC) List, the Childhood Trauma Questionnaire (CTQ), and the Positive and Negative Suicide Ideation (PANSI) Inventory. Results: The incidence of alexithymia was significantly higher among adolescents with depression (76.45%) during the pandemic. There were significant differences in school bullying, disease severity, ASLEC score, CTQ score and PANSI score between adolescents with and without alexithymia. In addition, learning stress, health and adaptation problems during the pandemic may be influential factors in alexithymia of adolescent depression (P < 0.05). Conclusions: According to the results, we found a high incidence of alexithymia in adolescent depression during the pandemic. More support and attention from families, schools and society is needed to develop preventive and targeted psychological interventions as early as possible.

Developing Emotional Skills and the Therapeutic Alliance in Clients with Alexithymia: Intervention Guidelines

Despite being a longstanding and well-established concept, alexithymia is unfamiliar for many clinicians. This article aimed to address the alexithymia concept from a clinical perspective based on a review of the research on alexithymia intervention. Several strategies are proposed to help clinicians better work with alexithymic clients in psychotherapy. Alexithymia assessment, its impact on the therapeutic alliance, and the difficulties in emotional tasks are highlighted points. Considering alexithymia will inform clinicians' current diagnosis and conceptualization and provide specific targets and venues for intervention, increasing the effectiveness of psychotherapy.

Alexithymia, infertility-related stress and quality of life in women undergoing an assisted reproductive treatment

The investigation of the association between alexithymia and quality of life in infertility is a relatively neglected area of research. The aim of this study was to evaluate the association between alexithymia and infertility-related quality of life in women during Assisted Reproductive Treatment. Data were collected in a clinic in Rome, 93 infertile women completed the 20-item Toronto Alexithymia Scale (TAS-20), the Fertility Quality of Life (FertiQoL) questionnaire and a socio-demographic questionnaire. TAS-20 total and two factors-Difficulty in Identifying Feelings (DIF) and Difficulty in Describing Feelings (DDF)-showed significant negative correlations with the overall questionnaire and with both Core and Treatment modules of FertiQoL. The regression model explained the 43% variance in FertiQol overall scores (R² = 0.43; adjusted R² = .38); a significant effect was reported for the number of previous attempts (beta = 0.20; p < .04), TAS-20 DIF (beta = -0.47; p < .001) and TAS-20 Externally Orientated Thinking (EOT) (beta = 0.20; p < .04); after applying Benjamini-Hochberg correction procedure only TAS-20 DIF maintained its significance. Alexithymia is associated with a worsened quality of life in infertile women; specifically, low difficulties in identifying feelings were associated to higher quality of life. Further investigations are needed also to develop specific therapeutic interventions aimed to promote emotional abilities in infertile people.

Alexithymia in People With Recurrent Suicide Attempts

Background: Alexithymia, an inability to identify or describe emotions, is associated with suicidality yet the correlation with single or repeated suicide attempts is less clear. Aims: We aimed to assess the modifiability of alexithymia following a group psychosocial intervention focused on improving emotional literacy in those with a history of recurrent suicide attempts (RSA). Method: A total of 169 participants with self-reported RSA completed pre- and postgroup assessments of a 20-week group therapy intervention. Questionnaires assessed alexithymia, depression, impulsivity, and hopelessness; the Toronto Alexithymia Scale (TAS-20) was the primary outcome. Data were analyzed using multiple imputation. Results: Participants had on average 7.8 lifetime suicide attempts, 73% were female, and 16.6% had a >13-point reduction in TAS-20 scores after 20 weeks. Directed acyclic graph (DAG) analysis demonstrated significant relationships between alexithymia, depression, hopelessness, problem-solving, and satisfaction with life. Age of onset of suicidality was the only factor predictive of postintervention TAS-20 score in univariate linear regression. Limitations: The study limitations were its sample size, insufficient resources, and missing data. Conclusion: A change in TAS scores indicated that alexithymia can be a modifiable treatment target. Being able to identify and describe feelings may lead to improvement in depression, hopelessness, problem-solving, and satisfaction with life in this population.

Psychodynamic Psychotherapy for Patients With Functional Somatic Disorders and the Road to Recovery

Patients with functional somatic disorders (FSDs) are commonly encountered in clinical practice and are often considered difficult to treat. This article summarizes recent advances in the understanding of these disorders that have opened new avenues for treatment. Findings concerning the role of three related key biobehavioral systems (attachment, mentalizing, and impairments in epistemic trust) that seem to be centrally involved in FSDs, as viewed from a psychodynamic perspective, are discussed as well as empirical evidence supporting the efficacy of psychodynamic psychotherapy for patients with FSDs. Finally, the basic treatment principles of dynamic interpersonal therapy, an integrative psychodynamic treatment adapted for patients with FSDs, are outlined through a description of the treatment of a woman with chronic widespread pain and irritable bowel syndrome.

Giving words to emotions: the use of linguistic analysis to explore the role of alexithymia in an expressive writing intervention

Expressive writing techniques are methods focusing on written emotional expression that require people to write about traumatic or difficult experiences, with the objective of promoting an elaboration of these events. The general aim of the study is to investigate the influence of alexithymia, a deficit in emotional regulation processes, on the effects of an expressive writing intervention, analyzing the writing protocols through the use of the Linguistic Inquiry and Word Count (LIWIC) and Referential Process (RP) linguistic measures via IDAAP software. Thirty-five women undergoing an assisted reproductive treatment participated in the study and filled out a sociodemographic questionnaire, the 20-item Toronto Alexithymia Scale. They also underwent three session of writing, following a request that they write about their emotions regarding their current situation. The women enrolled were divided into two groups: low alexithymia and high alexithymia, comprising individuals with a TAS-20 total score lower or higher than the mean, respectively. Analyses within the groups during the three writing sessions revealed that the women with low alexithymia reported a greater number of words expressing affectivity, sadness and future perspective, whereas no significances in the high alexithymia group emerged. Moreover, when analysing differences between the groups, high-alexithymia women reported lower scores in RP indexes and fewer words expressing sadness, future perspectives and we verbal. In conclusion, these preliminary findings may confirm the hypothesis that alexithymia affects the effectiveness of expressive writing through a difficulty in becoming involved in the writing process and a lack of symbolizing processes.

Importance of telling the unutterable: Alexithymia among sexually abused children

Child maltreatment is known to be an etiological factor for developing alexithymia which refers to the difficulty to identify and express feelings. Yet, scarce data is available regarding the vulnerability in child victims of sexual abuse to develop alexithymia. The current study aimed to compare level of alexithymia among a sample of school-aged victims of child sexual abuse (CSA) and a comparison group of non-victimized children. Results also investigated the mediational role of alexithymia in the association between CSA and both internalized and externalized behavior problems. The sample involved 429 sexually abused and 98 non-abused children aged 6 to 12 years old and their parents. The Children's Alexithymia Measure (Way et al., 2010) and the Child Behavior Checklist (Achenbach and Rescorla, 2001) were completed by parents. Clinicians filled out an adapted version of the History of Victimization Form to assess CSA characteristics (Hébert and Cyr, 2010). Analyses revealed that victims of CSA presented significantly higher levels of alexithymia compared to their non-abused counterparts. Results also highlighted the role of alexithymia mediating the association between CSA and both internalized and externalized behavior problems. Focussing on alexithymia is a promising avenue to sustain resilience and prevent further difficulties in sexually abused children.

Alexithymia and self-harm: A review of nonsuicidal self-injury, suicidal ideation, and suicide attempts

INTRODUCTION

Suicide attempts are a significant global public health concern. Research into non-traditional factors, such as the presence of alexithymia, may shed light on the prediction of suicidal behaviours, which can aid intervention and prevention strategies. To ascertain whether alexithymia is a unique risk factor for suicide attempts, this article reviews the evidence on alexithymia related to suicidal ideation, attempts, and non-suicidal self-injury (NSSI).

METHODS

A literature search was conducted for original articles examining the general and psychiatric populations.

RESULTS

There is consistent evidence linking alexithymia with suicidal ideation and NSSI, but inconsistent evidence linking it to suicide attempts.

CONCLUSION

The relationship between alexithymia and suicidality seems to differ based on whether the research focuses on suicidal ideation, suicide attempts, or NSSI. The relationship between alexithymia and suicidality can be understood within the context of multiple code theory and childhood trauma. Future research should explore the whether alexithymia can reliably distinguish between those with a single attempt and those with multiple suicide attempts as well as alexithymia levels pre- and post-intervention with suicide-related behavior as outcomes in treatment studies.

Alexithymic Traits and Somatic Symptoms in Children and Adolescents: a Screening Approach to Explore the Mediation Role of Depression

The association among alexithymia, somatic symptoms and clinical correlates has been scantly investigated in children. The present study examined alexithymic features and somatic symptomatology in schoolchildren with high and low levels of depression, testing the role of depressive symptoms in mediating the associations between alexithymia and somatic symptoms. Seven-hundred schoolchildren were involved in this study and divided into two subgroups (8-10 years and 11-14 years) in order to test differences according to the age. Participants completed the Children's Somatization Inventory-24 for the assessment of somatic symptoms, the Alexithymia Questionnaire for Children to evaluate alexithymic features and the Children's Depression Inventory-2 to investigate depressive symptoms. Results showed that children with high levels of depression reported both higher alexithymia and somatic symptoms levels. Despite a direct effect of alexithymia on somatic symptoms, the mediation analyses also highlighted an indirect effect of alexythimia on somatic symptoms through depressive symptoms. Findings suggested that a depressive symptomatology may clarify why schoolchildren with high alexithymia scores tend to report higher levels of health problems. Results also support the possibility that depressive symptoms may contribute to the development of somatic symptomatology among schoolchildren in the presence of high levels of alexithymia.

Unconscious Emotion and Free-Energy: A Philosophical and Neuroscientific Exploration

Unconscious emotions are of central importance to psychoanalysis. They do, however, raise conceptual problems. The most pertinent concerns the intuition, shared by Freud, that consciousness is essential to emotion, which makes the idea of unconscious emotion seem paradoxical. In this paper, I address this paradox from the perspective of the philosopher R. C. Roberts' account of emotions as concern-based construals. I provide an interpretation of this account in the context of affective neuroscience and explore the form of Freudian repression that emotions may be subject to under such an interpretation. This exploration draws on evidence from research on alexithymia and utilises ideas from free-energy neuroscience. The free-energy framework, moreover, facilitates an account of repression that avoids the homunculus objection and coheres with recent work on hysteria.

Panic Disorder as Unthinkable Emotions: Alexithymia in Panic Disorder, a Croatian Cross-Sectional Study

OBJECTIVES

Previous research on alexithymia has led to controversy over its prevalence in panic disorder. The aim of this study was to assess the difference in the prevalence of alexithymia in panic disorder and other anxiety disorders.

DESIGN AND METHODS

We performed a cross-sectional study on a sample of 71 patients diagnosed with panic disorder and 113 patients diagnosed with other anxiety disorders; both groups were 18-50 years old. Primary outcome was the 20-item Toronto Alexithymia Scale (TAS) score. Secondary outcome was the prevalence of alexithymia defined as a TAS score ≥61.

RESULTS

Patients diagnosed with panic disorder had a 25% higher score on the TAS subscale of difficulty identifying feelings than patients diagnosed with other anxiety disorders. The prevalence of alexithymia was 27% in patients with panic disorder and 13% in patients with other anxiety disorders. Patients diagnosed with panic disorder had significantly higher odds for alexithymia.

CONCLUSIONS

The results of our study support the hypothesis of higher prevalence of alexithymia in individuals with panic disorder than in individuals with other anxiety disorders. In addition, difficulty identifying feelings as a salient feature of alexithymia is higher in panic disorder than in other anxiety disorders.

A Scientometric Review of Alexithymia: Mapping Thematic and Disciplinary Shifts in Half a Century of Research

The term "alexithymia" was introduced in the lexicon of psychiatry in the early '70s by Sifneos to outline the difficulties manifested by some patients in identifying and describing their own emotions. Since then, the construct has been broadened and partially modified. Today this describes a condition characterized by an altered emotional awareness which leads to difficulties in recognizing your own and others' emotions. In half a century, the volume of scientific products focusing on alexithymia has exceeded 5,000. Such an expansive knowledge domain poses a difficulty for those willing to understand how alexithymia research has developed. Scientometrics embodies a solution to this issue, employing computational, and visual analytic methods to uncover meaningful patterns within large bibliographical corpora. In this study, we used the CiteSpace software to examine a corpus of 4,930 publications on alexithymia ranging from 1980 to 2020 and their 100,251 references included in Web of Science. Document co-citation analysis was performed to highlight pivotal publications and major research areas on alexithymia, whereas journal co-citation analysis was conducted to find the related editorial venues and disciplinary communities. The analyses suggest that the construct of alexithymia experienced a gradual thematic and disciplinary shift. Although the first conceptualization of alexithymia came from psychoanalysis and psychosomatics, empirical research was pushed by the operationalization of the construct formulated at the end of the '80s. Specifically, the development of the Toronto Alexithymia Scale, currently the most used self-report instrument, seems to have encouraged both the entrance of new disciplines in the study of alexithymia (i.e., cognitive science and neuroscience) and an implicit redefinition of its conceptual nucleus. Overall, we discuss opportunities and limitations in the application of this bottom-up approach, which highlights trends in alexithymia research that were previously identified only through a qualitative, theory-driven approach.

More Than Words Can Say: A Multi-Disciplinary Consideration of the Psychotherapeutic Evaluation and Treatment of Alexithymia

Alexithymia is a disorder that stands at the border of mind and body, with psychological/affective and physiological/experiential disturbances. The purpose of this article is to propose a new clinical access point for the evaluation and treatment of the deficits in emotional awareness demonstrated in alexithymia. This will be based on insights from recent neuroscientific research, which is adding to the psychodynamic understanding of alexithymia, regarding clinical presentation and etiology. Following a brief review of definitions, forms of measurement, and potential etiologic elements of alexithymia, current neuroscientific theory and research into "predictive processing" approaches to brain function will be outlined, including how "interoception" and "interoceptive inference" underpins emotion and emotional awareness. From this synergistic perspective, I will outline how interoceptive inference provides a key to the link between: problems in early life relational experiences and the patient's long held, but suboptimal models of their inner and outer world. This is reflected in the deficits in affective experiencing and emotional awareness described in alexithymia. Three clinical cases will be presented to illustrate this nuanced consideration of alexithymic etiology and treatment. The implications of the historical, psychological, and somatic aspects of experience will be considered, regarding the patients' diminished ability to: experience and represent emotional experience as distinct feeling states; signify the relevant meaning of affective experience; and incorporate such with cognitions to adaptively guide behavior. These will be addressed using psychometric, psychological, neuro-cognitive, and neurocomputational approaches. Elements from current theory, research, and treatment of alexithymia, will be highlighted that are salient to the clinician, in order to support their understanding of patients against the backdrop of current psychodynamic and neuroscientific research, which will thereby increase treatment options and benefits. The focus, and conclusion, of this article is the role that attention to interoception can play (within the safety of the therapeutic relationship and within any therapeutic process) in allowing updating of the patient's strongly held but dysfunctional beliefs.

Importance of considering interoceptive abilities in alexithymia assessment

Background

Recent studies have shown that people with high alexithymia scores have decreased interoceptive abilities, which can be associated with psychological and physical disorders. Early assessments of the alexithymia trait included the evaluation of these abilities through the dimension measuring the difficulty in identifying and distinguishing between feelings and bodily sensations (the 26-item Toronto Alexithymia Scale; TAS-26). The revised version of the TAS, the TAS-20, contains a three-factor solution that does not involve a dimension assessing interoceptive abilities. However, the three items allowing the evaluation of these abilities are still present in the TAS-20. In this context, we hypothesized that the 3 items which assess interoceptive abilities in the TAS-20 should constitute an independent factor. In addition to exploring the internal structure of the TAS-20, we examined its external validity by assessing the relationships between the new factors and self-reported measures of personality trait and psychological and physical health.

Method

Two online studies (N = 253 and N = 287) were performed. The participants completed the TAS-20 and a set of psychological questionnaires (e.g., anxiety, depression) and health questions (e.g., “Do you suffer from a somatic disorder?”). The structure of the TAS-20 was examined using exploratory factor analysis (EFA), followed by an investigation of the relationships between the resulting new factors and other psychological and health data using regressions. In both studies, EFA revealed a new structure of the questionnaire consisting of four dimensions: (1) difficulty in the awareness of feelings, (2) externally oriented thinking, (3) difficulty in interoceptive abilities, and (4) poor affective sharing. The first factor was positively associated with all self-reported psychological and personality trait measures while the third factor was associated more with somatic disorders and medication intake.

Results

Our results suggest the presence of a new latent factor in the assessment of alexithymia that reflects interoceptive abilities specifically related to health and personality trait outcomes. In accordance with the results and the literature, it seems important to include an assessment of interoceptive abilities when considering the evaluation of alexithymia. The next step would be to develop a valid measure of these abilities.

Maladaptive Personality Functioning and Psychopathological Symptoms in Problematic Video Game Players: A Person-Centered Approach

BACKGROUND

A need exists to increase our understanding of the association between maladaptive personality traits, psychopathological symptoms, game preference, and different types of video game use. In the present study, we used a person-centered approach to identify different subtypes of video game players and we explored how they differ in personality profiles, clinical symptoms, and video game usage.

METHODS

We assessed problematic gaming via the nine-item Internet Gaming Disorder Scale and self-reported screen time playing video games in a sample of 366 adolescents and young adult gamers. Participants also completed measures on maladaptive personality domains (Personality Inventory for DSM-5 Brief Form), alexithymia (Toronto Alexithymia Scale-20 items), and psychopathological symptoms (DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure) and reported which genre of video games they preferred.

RESULTS

Using a person-centered, cluster-analytic approach, we identified four clusters of video game players (Occasional, Passionate, Preoccupied, and Disordered) presenting peculiar combinations of problematic gaming scores and time spent online playing video games. Non-problematic gamers (Occasional and Passionate) represented the majority of the sample (62.3% of the participants). Highly involved gamers who exhibited excessive screen time playing video games (Disordered gamers) presented the highest level of maladaptive personality traits and psychopathological symptoms, and were characterized by the greatest use of Multiplayer Online Battle Arena (MOBA) games.

CONCLUSION

These results have clinical implications on suggesting the importance to determining whether or not problematic gaming activities reflect a dysfunctional emotion-focused coping strategy to avoid inner unpleasant emotional or a more generally compromised emotional and social functioning.
