Measures Of Alexithymia Research Articles

Alexithymia and intolerance of uncertainty predict somatic symptoms in autistic and non-autistic adults.

Autistic people have more physical health problems than non-autistic people. We were interested in whether autistic people experience more discomfort in their bodies than non-autistic people and whether certain psychological traits contribute to that. A survey was completed online by older adolescents and adults, 51 of whom were autistic, 32 of whom thought they might be autistic but were not diagnosed and 119 who were not autistic. They completed measures of somatic symptoms (daily experience of pain, discomfort, dizziness), alexithymia (difficulty identifying and expressing feelings), interoception (how much people are aware of their bodies) and intolerance of uncertainty (how people handle doubt or uncertainty), and reported any physical or mental health conditions. We found that the autistic participants had more physical and mental health conditions than the non-autistic participants, but even when we took account of this, they experienced higher levels of somatic symptoms. We looked at which psychological factors influenced levels of somatic symptoms across the whole sample, and found that alexithymia, intolerance of uncertainty, having physical health problems, being female and the number of mental health conditions predicted somatic symptoms, while interoception and autism diagnosis did not. The findings suggest that people may be more likely to experience physical discomfort if they are female, and have difficulty identifying and expressing feeling and difficulty tolerating doubt. As these psychological factors are more prominent in autism, we think this is important for physical and mental health providers to know about, so that these psychological factors can be considered when assessing and treating autistic people.

Assessing Alexithymia across Asian and Western Cultures: Psychometric Properties of the Perth Alexithymia Questionnaire and Toronto Alexithymia Scale-20 in Singaporean and Australian Samples

Alexithymia refers to difficulties identifying feelings (DIF), describing feelings (DDF), and externally orientated thinking (EOT). Originally conceptualized by American psychiatrists, some researchers have since questioned the validity and application of this construct in Asian cultures. However, to date, there is little empirical work formally assessing the invariance of alexithymia across Asian and Western cultures. The present study aimed to help address this gap, by examining the psychometric properties and measurement invariance of two alexithymia measures, the Perth Alexithymia Questionnaire (PAQ) and Toronto Alexithymia Scale-20 (TAS-20), across samples from Singapore (n = 434) or Australia (n = 489). The same theoretically congruent factor structure was supported across both samples; this structure was fully invariant across samples for the PAQ, and partially invariant for the TAS-20. Both measures had good internal consistency and concurrent validity across samples, except the TAS-20 EOT subscale which had low internal consistency and factor loadings in both samples. The Singaporean sample reported higher DIF and DDF for positive emotions than the Australian sample. Overall, our results support the cross-cultural validity and application of the alexithymia construct. The PAQ and TAS-20 both appear to have good utility in this respect, though the PAQ may provide a more detailed facet-level profile.

Alteration of interoceptive sensitivity: expanding the spectrum of behavioural disorders in amyotrophic lateral sclerosis

BackgroundAmyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder with progressive loss of upper and lower motor neurons. Non-motor-symptoms, such as cognitive, emotional, autonomic, and somatosensory alterations, have been also described.Interoception represents the link between the body and brain, since it refers to the ability to consciously perceive the physical condition of the inner body, including one’s heartbeat (i.e., interoceptive sensitivity, IS).ObjectivesTo evaluate IS in ALS patients by means of a well-established task: the heartbeat perception task. Moreover, we evaluated possible correlations between IS and neuropsychological, affective, and disease-related characteristics.MethodsFifty-five ALS patients (mean-age = 60.3 ± 12.5 years; mean disease-duration = 20.9 ± 18.8 months) and 41 caregivers (CG) underwent the heartbeat perception task and an extensive evaluation of motor, cognitive, body awareness, affective, and emotion domains.ResultsALS patients showed lower IS than CG (0.68 ± 0.24 vs 0.82 ± 0.16; p = 0.003). Significant correlations were found between IS and self-reported measures of alexithymia (subscale of Toronto Alexithymia scale-20 “difficulties in describing feelings”; rho = − .391, p = .003) and interoceptive awareness (subscale of Multidimensional assessment of interoceptive awareness “not worrying about pain”; rho = .405, p = .002). No significant differences were found on questionnaires for depression and anxiety between patients with ALS and their caregivers (p > .05).ConclusionsALS patients show reduced interoceptive sensitivity that is associated with poorer ability to describe feelings and with lower focalization on pain, regardless of cognitive and motor impairment. Alteration of interoception may represent a specific behavioural sign within the spectrum of emotion processing deficits described in ALS patients.

Psychometric properties of the emotional processing scale in individuals with psychiatric symptoms and the development of a brief 15-item version

The 25-item Emotional Processing Scale (EPS) can be used with clinical populations, but there is little research on its psychometric properties (factor structure, test–retest reliability, and validity) in individuals with psychiatric symptoms. We administered the EPS-25 to a large sample of people (N = 512) with elevated psychiatric symptoms. We used confirmatory factor analysis to evaluate three a priori models from previous research and then evaluated discriminant and convergent validity against measures of alexithymia (Toronto Alexithymia Scale-20), depressive symptoms (Patient Health Questionaire-9), and anxiety symptoms (Generalized Anxiety Disorder-7). None of the a priori models achieved acceptable fit, and subsequent exploratory factor analysis did not yield a clear factor solution for the 25 items. A 5-factor model did, however, achieve acceptable fit when we retained only 15 items, and this solution was replicated in a validation sample. Convergent and discriminant validity for this revised version, the EPS-15, was r = − 0.19 to 0.46 vs. TAS-20, r = 0.07− 0.25 vs. PHQ-9, and r = 0.29− 0.57 vs. GAD-7. Test–retest reliability was acceptable (ICC = 0.73). This study strengthens the case for the reliability and validity of the 5-factor structure of the EPS but suggest that only 15 items should be retained. Future studies should further examine the reliability and validity of the EPS-15.

Mediating role of depression in the association between alexithymia and nonsuicidal self-injury in a representative sample of adolescents in Taiwan

BackgroundNock’s (2009) integrated theoretical model suggests that specific intrapersonal vulnerability factors caused by distal risk factors contribute to the development of nonsuicidal self-injury (NSSI). Alexithymia and depression have been found to predict NSSI. Based on Nock’s model, alexithymia plays a distal risk factor role to increase the risk of depression—an intrapersonal vulnerability factor—and further increase the risk of NSSI. However, small or unrepresentative samples in past studies limit the generalizability of the results. This study examined the roles of depression and alexithymia in predicting NSSI, as well as the mediating effect of depression in the relation between alexithymia and NSSI in a large representative sample of adolescents in Taiwan.MethodsUsing a cross-sectional study design, a large representative sample of 2,170 senior high school students in Taiwan was assessed by self-report measures of alexithymia, depression, and NSSI. Mediation analyses were performed to examine whether the relation between alexithymia and NSSI was mediated by depression. The questionnaires were administered in classrooms.ResultsResults showed that alexithymia positively predicted NSSI (β = 0.23, p < .001) and depression can also positively predict NSSI (β = 0.41, p < .001). Additionally, the association between alexithymia and NSSI was fully mediated by depression.ConclusionsThis study data provided evidence for the mediating role of depression between alexithymia and NSSI, which can be explained by Nock’s (2009) integrated theoretical model. The implications of the findings for future research and intervention were discussed.

Alexithymia and binge eating: Maladaptive emotion regulation strategy or deficient interoception?

Alexithymia has been linked to various excessive behaviors as a likely risk factor, including binge eating. Such relationships are often attributed to deficient emotional self-regulation in alexithymia, ostensibly leading to the use of maladaptive, externalized behaviors as strategies for coping with distress. An alternative view is that alexithymia reflects a fundamental deficit of interoceptive awareness that, in the case of binge eating, would suggest that internal satiety cues are poorly recognized, promoting overconsumption. The present study assessed the relationship between alexithymia and binge eating in the context of these competing hypotheses. A large online sample of young adults (n = 532) completed validated measures of alexithymia, emotion regulation, interoception, binge eating, emotional eating motivation, and sensitivity to reward and punishment. Correlations were as expected except for interoception, which showed minimal association with alexithymia or binge eating. In a hierarchical regression controlling for age, gender, education level and student status as covariates, binge eating was predicted by emotional eating motivation, emotion regulation (a negative predictor), alexithymia, and reward sensitivity, with the final model explaining 53% of variance in binge eating. Bootstrapped path analyses controlling for all other variables indicated that the relationship between alexithymia and binge eating was mediated by deficient emotion regulation but not deficient interoception, and that the relationships of both alexithymia and emotion regulation with binge eating were mediated by emotional eating motivation. Results are consistent with the notion that the association of alexithymia with binge eating reflects deficient emotion regulation in alexithymia, which can lead to adoption of maladaptive, externalized behaviors such as binge eating for coping with distress.

Increased spontaneous fronto-central oscillatory power during eye closing in patients with multiple somatic symptoms

Functional somatic symptoms (FSS) are typically associated with excessive thoughts, feelings and behaviors related to the physical symptoms whether these symptoms are unequivocally associated with a diagnosed medical condition. However, less evidence is available concerning the neurocognitive deficits underlying these features of FSS. This study aimed to examine the resting-state oscillatory activities during both eye-opening and eye-closure states in individuals with FSS. Sixty-six FSS patients screened with PHQ-15 received two 10-minute sessions of EEG assessments. All completed clinical measurements on depression, anxiety, and psychological measurements on personality traits and alexithymia. Patients scoring high on PHQ-15 (the multiple somatic symptom (MSS) or SS-high group) demonstrated increased powers in central channels (C3 and C4) in low-beta band and in the left-frontal channel (F3) in high-gamma band, during eye-closure states. Patients with higher scores in depression were more likely to be classified as the SS-high group. SS-high patients demonstrated increased difficulties in describing and identifying emotions, and less reduced day-dreaming. The combined findings in increased fronto-central high-frequency activities and alexithymia measures suggest MSS patients are associated with enhanced internally-oriented thinking and cognitive simulation which may lead to intensified feelings of simulated events and misattribution of symptoms. Future treatments should focus on eliminating cognitive bias and enhancing accuracy in interoceptive awareness.

Alexithymia and Athletic Performance: Beneficial or Deleterious, Both Sides of the Medal? A Systematic Review.

Background: Numerous studies have been published on alexithymia among athletes in the last decades. The objective, here, is to provide a critical review on alexithymia in sport and identify elements demonstrating that alexithymic athletes can attain a competitive advantage. Methods: The Center for Reviews and Dissemination guidelines were used. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines served as the template for reporting the present systematic review. We searched PubMed, Embase, Science Direct, and PsycINFO, without language or date restrictions. Results: Within 72 eligible studies, 23 articles fulfilling the selection criteria were included in the review. Alexithymia is associated with various pathologies and considered to be counter-performing. However, despite considerable suspicion of an advantageous performance effect of alexithymia, there is a lack of data to quantify this effect. Studies identified are heterogeneous (different scales of measurement of alexithymia used or outcomes, different sports), that do not allow us to conclude on an observed causal relationship, because the studies are mostly observational. Conclusion: This systematic review opens a new search field on alexithymia, as possibly promoting performance.

Alexithymia, narcissism and social anxiety in relation to social media and internet addiction symptoms.

There has been considerable interest in trait correlates of excessive or problematic use of the internet, known as internet addiction. However, the concept of internet addiction has been criticised as too broad. Specific forms of excessive internet use, for example, social media, may have different trait correlates compared to internet use in general. The present study compared levels of internet and social media addiction symptoms in relation to three traits previously linked to one or the other form of excessive behaviour: alexithymia, narcissism and social anxiety. There were 217 young adult social media- and internet-using participants aged 18-35 years recruited from two university campuses in southeast Queensland, Australia. They completed an online questionnaire battery that included a demographics questionnaire and widely used, validated measures of narcissism, alexithymia and social anxiety. Hierarchical regressions indicated that after controlling for demographic variables, internet addiction symptoms were predicted by social anxiety, narcissism and alexithymia, whereas social media addiction symptoms were predicted only by social anxiety and narcissism. Results suggest that the association of alexithymia with internet addiction symptoms does not encompass excessive use of social media, and support the contention that the concept of internet addiction may be too broad.

Alexithymia, attachment security and negative mood

ABSTRACT Objective Alexithymia, a trait dimension defined by difficulties identifying and describing feelings and an externally oriented thinking style, is often associated with negative moods such as depression, anxiety and stress as well as an insecure adult attachment style. The present study evaluated the hypothesis that the link between alexithymia and negative moods is mediated by insecure attachment, which implies a lack of social resources for coping with distress. Method A nonclinical online community sample of 206 male and female young adults recruited from throughout Australia completed validated measures of alexithymia, attachment security and negative moods. Results In a hierarchical regression model with demographic variables and socially desirable responding at step 1, alexithymia at step 2 and insecure attachment at step 3, the final model accounted for 62.4% of variance in negative moods, with alexithymia and insecure attachment as significant predictors. Bootstrapped mediation modelling, controlling for demographic variables and socially desirable responding, indicated partial mediation of the association between alexithymia and negative moods by insecure attachment. Conclusions Results point to the role of insecure attachment in the negative moods often associated with alexithymia, presumably in addition to the deficient emotional self-regulation associated with alexithymia. KEY POINTS What is already known about this topic: Alexithymia is associated with negative moods and maladaptive coping. Alexithymia is associated with insecure adult attachment styles. Alexithymia is associated with loneliness and interpersonal difficulties.What this topic adds: Insecure attachment mediated the association of alexithymia with negative moods. This suggests the role of insecure attachment in negative moods associated with alexithymia. Therapy for alexithymic clients may thus benefit from targeting insecure attachment, but replication is needed in clinical samples.

The Relationship Between Alexithymia and Mobile Phone Addiction Among Mainland Chinese Students: A Meta-Analysis.

Alexithymia and mobile phone addiction are common phenomena in daily life. Many studies have explored the internal relationship between them based on different theoretical perspectives, but the extent of the exact correlation is still controversial. To address this controversy and clarify the reasons for the divergence, a meta-analysis of 26 articles comprising 23,387 Chinese students was conducted. The results show that alexithymia was highly positively correlated with mobile phone addiction (r = 0.41, 95% CI = [0.37, 0.45]). Furthermore, the relationship was moderated by mobile phone addiction measurement tool and year of publication, with studies using the Mobile Phone Addiction Tendency Scale (MPATS) having higher correlation coefficients than those using the Mobile Phone Addiction Index (MPAI) or other measurement tools. Studies published in 2020–2021 yielded higher correlations than those published in 2014–2016 and 2017–2019. However, the relationship was not moderated by gender, region, or measures of alexithymia. Therefore, our meta-analysis of available published data indicated that alexithymia and mobile phone addiction in Chinese students are not only highly positively correlated but also affected by mobile phone addiction measurement tools and publication year. Longitudinal studies or experimental studies should be strengthened in the future to further establish the direction(s) of causality for the relation between alexithymia and mobile phone addiction.

A Semantic Scale Network analysis of the revised Mystical Experiences Questionnaire: A call for collaboration

Abstract Background and aims Multiple laboratories have proposed measures of subjective effects of psychedelics as potential mediators of their therapeutic impact. Other work has identified individual differences that covary with subjective responses in informative ways. The range of potential measures of responses, traits, and outcomes is vast. Ideas for new measures are likely numerous. The field will progress efficiently if proposed new scales can add incremental validity. Semantic Scale Network analyses identify conceptual overlap among scales based on items (rather than participant ratings), which could help laboratories avoid putting effort into measures that are unlikely to account for unique variance. Semantic Scale Network analyses can also reveal links to constructs from disparate research literatures, potentially helping investigators generate novel hypotheses and explain connections among disparate findings. The results of Semantic Scale Network analyses have the potential to improve as more investigators enter their scales into the corpus. Method Example analyses using the revised Mystical Experiences Questionnaire (MEQ) underscore the uniqueness and discriminant validity of the MEQ subscales. Results Findings dovetail with published theorizing and suggest potentially novel links with different therapeutic effects. The MEQ total or subscales overlap with measures of awe, inspiration, regret, dissatisfaction, transcendence, depression, fatigue, and spirituality. Links with measures of stress, alexithymia, and gender identity suggest lines of further work. Conclusions This analytic approach might suggest unique applications for psychedelic-assisted treatments and provide perspectives on phenomena outside the field. As psychedelic researchers enter their scales to the corpus for Semantic Scale Network analyses, the field will benefit.

Assessing alexithymia in adults with acquired brain injury: Psychometric properties of the Perth Alexithymia Questionnaire

BackgroundAlexithymia is a multidimensional personality trait comprised of difficulty identifying feelings, difficulty describing feelings, and externally orientated thinking. The assessment of alexithymia in people with acquired brain injury (ABI) is of clinical interest because alexithymia is linked to poor psychosocial functioning and community reintegration after ABI. To date, alexithymia measures have not been psychometrically investigated/validated in an ABI sample, restricting confident empirical work in this area. We aimed to fill this gap by assessing the psychometric properties of the Perth Alexithymia Questionnaire (PAQ) in adults with ABI and determining whether the alexithymia construct manifests similarly in ABI samples compared to the general community. MethodsThe PAQ and Depression Anxiety Stress Scales-21 were administered to an ABI sample (N = 350) and a community sample (N = 1012). Factor structure, measurement invariance, internal consistency reliability, and concurrent/discriminant validity were explored. ResultsOur confirmatory factor analysis of the PAQ supported the intended five-factor correlated model as the best solution, where items loaded well onto the five intended subscales. This factor structure was invariant across ABI and community samples. Good reliability and concurrent and discriminant validity were also established. LimitationsThe PAQ is a self-report measure and may be impacted by insight deficits known to occur after ABI. ConclusionOur data suggests that the PAQ has good validity and reliability as a measure of alexithymia. The latent structure of alexithymia manifests similarly in ABI and community samples. This study provides the first psychometric foundation for confident assessment of alexithymia in ABI.

Clarifying the relationship between alexithymia and subjective interoception.

The long-standing hypothesis that emotions rely on bodily states is back in the spotlight. This has led some researchers to suggest that alexithymia, a personality construct characterized by altered emotional awareness, reflects a general deficit in interoception. However, tests of this hypothesis have relied on heterogeneous assessment methods, leading to inconsistent results. To shed some light on this issue, we administered a battery of self-report questionnaires of interoception and alexithymia to three samples from Italy, the U.S., and Singapore (N = 814). Correlation and machine learning analyses showed that alexithymia was associated with deficits in both subjective interoceptive accuracy and attention. Alexithymics’ interoceptive deficits were primarily related to difficulty identifying and describing feelings. Interoception showed a weaker association with externally-oriented thinking as operationalized by the Toronto Alexithymia Scale (TAS-20) and no association with the affective dimension of alexithymia later introduced by the Bermond-Vorst Alexithymia Questionnaire (BVAQ). We discuss our results with reference to the theoretical and psychometric differences between these two measures of alexithymia and their shortcomings. Overall, our results support the view that interoceptive deficits are a core component of alexithymia, although the latter cannot be reduced to the former.

The role of alexithymia and autistic traits in predicting quality of life in an online sample

BackgroundAutistic people tend to report poorer Quality of Life (QOL) than comparison groups, though some studies do report more optimistic findings. Higher autistic traits are also related to poorer QOL. However, the role of alexithymia in this relationship has not been explored. MethodA total of 163 participants (N = 53 autistic and N = 111 comparison) consented to take part; however, 30 participants were excluded due to missing data (who did not differ from those who were retained on age, gender, education, employment, or living status), leaving a final sample of 133 (N = 42 Autistic and 91 Comparison participants). Demographic information (including age, gender) was collected, alongside self-report measures of autistic traits, mental health, alexithymia, and QOL. We estimated regression models based on pre-registered analysis, and we conducted exploratory network analyses. ResultsAlexithymic traits did not predict QOL when controlling for covariates. Depression significantly predicted Physical, Psychological, and Social QOL. When examining the impact of just alexithymic traits and autistic traits, both were significantly associated with Physical and Psychological QOL. For participants with a low depression score, the correlation between alexithymia and QOL was strong; suggesting that depression occludes the association between alexithymia and QOL. Network analyses suggested that depression and anxiety exert direct effects on Physical and Psychological QOL, whereas alexithymia scores may influence Physical QOL via autistic traits. ConclusionIn sum, depression is a pervasive negative predictor of multiple QOL domains. The role of alexithymia in predicting QOL dimensionally and categorically was not ruled out, given our exploratory analyses, we suggest that interventions which target alexithymia may positively impact QOL for those who score low on depressive symptoms.

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

BackgroundThe 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. MethodsThe 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. ResultsThe 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. LimitationsEmotional 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. ConclusionsOur 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.

Alexithymia is a mediating factor in the relationship between adult attachment and severity of depression and social anxiety

BackgroundMajor depressive disorder (MDD) and social anxiety disorder (SAD) are commonly occurring conditions, either alone or together (MDD-SAD). Recent research linked insecure attachment and alexithymia to MDD and/or SAD, indicating that the way affected individuals relate interpersonally and their ability to identify and communicate emotions are pertinent issues. The current study investigated the mediating role of alexithymia in the relationship between insecure attachment and severity of MDD and SAD symptoms. MethodUsing the SCID-I, participants (N=159) were identified as MDD-only (n=43), MDD-SAD (n=56), or a healthy control (n=60). Participants completed measures of adult attachment, depression, social anxiety and alexithymia (defined as difficulty identifying and describing feelings). A two-step mediation analysis approach recommended by Shrout and Bolger determined if alexithymia mediates the relationship between attachment-depression and attachment-social anxiety. ResultsWhile alexithymia was high in MDD-only and MDD-SAD groups, individuals with MDD-SAD had significantly greater difficulty describing feelings. Alexithymia was a full mediator between attachment avoidance and depression, but only a partial mediator between attachment anxiety and depression. Meanwhile, alexithymia was a partial mediator for both attachment dimensions and social anxiety. LimitationsCausal inferences regarding insecure attachment, alexithymia, and MDD and SAD cannot be assumed given the cross-sectional data. The ‘externally oriented thinking’ component in alexithymia was also excluded from analyses due to low reliability. ConclusionThe results suggest emotional awareness and expression play a role in the illness severity for MDD and SAD—particularly in those with high attachment avoidance, offering a possible target for treatment and prevention strategies.

Improving the measurement of alexithymia in autistic adults: a psychometric investigation of the 20-item Toronto Alexithymia Scale and generation of a general alexithymia factor score using item response theory

BackgroundAlexithymia, a personality trait characterized by difficulties interpreting emotional states, is commonly elevated in autistic adults, and a growing body of literature suggests that this trait underlies several cognitive and emotional differences previously attributed to autism. Although questionnaires such as the 20-item Toronto Alexithymia Scale (TAS-20) are frequently used to measure alexithymia in the autistic population, few studies have investigated the psychometric properties of these questionnaires in autistic adults, including whether differential item functioning (I-DIF) exists between autistic and general population adults.MethodsThis study is a revised version of a previous article that was retracted due to copyright concerns (Williams and Gotham in Mol Autism 12:1–40). We conducted an in-depth psychometric analysis of the TAS-20 in a large sample of 743 cognitively able autistic adults recruited from the Simons Foundation SPARK participant pool and 721 general population controls enrolled in a large international psychological study. The factor structure of the TAS-20 was examined using confirmatory factor analysis, and item response theory was used to generate a subset of the items that were strong indicators of a “general alexithymia” factor. Correlations between alexithymia and other clinical outcomes were used to assess the nomological validity of the new alexithymia score in the SPARK sample.ResultsThe TAS-20 did not exhibit adequate model fit in either the autistic or general population samples. Empirically driven item reduction was undertaken, resulting in an 8-item general alexithymia factor score (GAFS-8, with “TAS” no longer referenced due to copyright) with sound psychometric properties and practically ignorable I-DIF between diagnostic groups. Correlational analyses indicated that GAFS-8 scores, as derived from the TAS-20, meaningfully predict autistic trait levels, repetitive behaviors, and depression symptoms, even after controlling for trait neuroticism. The GAFS-8 also presented no meaningful decrement in nomological validity over the full TAS-20 in autistic participants.LimitationsLimitations of the current study include a sample of autistic adults that was majority female, later diagnosed, and well educated; clinical and control groups drawn from different studies with variable measures; only 16 of the TAS-20 items being administered to the non-autistic sample; and an inability to test several other important psychometric characteristics of the GAFS-8, including sensitivity to change and I-DIF across multiple administrations.ConclusionsThese results indicate the potential of the GAFS-8 to robustly measure alexithymia in both autistic and non-autistic adults. A free online score calculator has been created to facilitate the use of norm-referenced GAFS-8 latent trait scores in research applications (available at https://asdmeasures.shinyapps.io/alexithymia).

The Association between Parent and Child-Report Measures of Alexithymia in Children with and without Developmental Language Disorder.

Accurate measures of alexithymia, an inability to recognise and describe one’s own emotions, that are suitable for children are crucial for research into alexithymia’s development. However, previous research suggests that parent versus child reports of alexithymia do not correlate. Potentially, children may report on the awareness of their emotions, whereas parent-report measures may reflect children’s verbal expression of emotion, which may be confounded by children’s communicative abilities, especially in conditions such as Developmental Language Disorder (DLD). Given theoretical arguments that alexithymia may develop due to language impairments, further research into alexithymia in DLD is also needed. This project examined parent and child report measures of alexithymia in children with DLD (n = 106) and without DLD (n = 183), and their association to children’s communication skills. Parent and child reports were not significantly correlated in either group, and children with DLD had higher alexithymia scores on the parent-report measure only. Thus, parent and child measures of alexithymia likely reflect different constructs. Pragmatic language problems related to more parent-reported alexithymia, over and above group membership. Structural language abilities were unrelated to alexithymia. We suggest decreased social learning opportunities, rather than a language measure artefact, underlie increased alexithymic difficulties in DLD.

Trait Emotional Intelligence and School Burnout Discriminate Between High and Low Alexithymic Profiles: A Study With Female Adolescents.

Alexithymic traits, which entail finding it difficult to recognize and describe one’s own emotions, are linked with poor trait emotional intelligence (TEI) and difficulties in identifying and managing stressors. There is evidence that alexithymia may have detrimental consequences for wellbeing and health, beginning in adolescence. In this cross-sectional study, we investigated the prevalence and incidence of alexithymia in teenage girls, testing the statistical power of TEI and student burnout to discriminate between high- and low-alexithymic subjects. A sample of 884 female high school students (mean age 16.2 years, age range 14–19) attending three Italian academic-track high schools (social sciences and humanities curriculum) completed self-report measures of alexithymia, school burnout, and TEI. Main descriptive statistics and correlational analysis preceded the discriminant analysis. The mean alexithymia scores suggest a high prevalence of alexithymia in female adolescents; as expected, this trait was negatively correlated with TEI and positively associated with school burnout. Participants with high vs. low alexithymia profiles were discriminated by a combination of TEI and burnout scores. High scores for the emotionality and self-control dimensions of TEI were strongly associated with membership of the low alexithymia group; high scores for the emotional exhaustion dimension of school burnout were indicative of membership of the high alexithymia group. These findings suggest crucial focuses for educational intervention: efforts to reduce the risk of emotional exhaustion and school burnout should especially concentrate on enhancing emotional awareness and self-control skills, both strongly associated with low levels of alexithymia.
