Measures Of Alexithymia Research Articles

Toronto Alexithymia Scale-20: Examining 18 Competing Factor Structure Solutions in a U.S. Sample and a Philippines Sample.

The Toronto Alexithymia Scale-20 is arguably the most utilized measure of alexithymia. Although a three-factor solution has been found by numerous studies, these findings are not universal. This article examined and compared 18 competing factor structures for the Toronto Alexithymia Scale-20, which included between one and four correlated latent factor structures, common methods models that accounts for negatively worded items, and bifactor models. Although the two-factor bifactor model with a common methods factor had the better model fit compared with the other 17 models examined, it still did not achieve the requisites of a good model fit across all model fit indices. Issues stemmed primarily from the externally oriented thinking factor and the negatively worded items. Post hoc analyses indicated that a two-factor bifactor model with the negatively worded items dropped achieved the requisites of a good model fit and can be treated as a unidimensional measure despite the presence of multidimensionality. Multiple-group analysis indicated that the factor loadings were invariant across U.S. and Philippines samples. After controlling for noninvariance at the item intercept level, the Philippines sample had a higher alexithymia general score compared with the U.S. sample.

Alexithymic traits can explain the association between puberty and symptoms of depression and anxiety in adolescent females.

Symptoms of internalizing disorders such as depression and anxiety increase in adolescence, especially in females. However, gender differences in depression and anxiety symptoms emerge only after puberty onset. Levels of alexithymia, characterized by difficulties identifying and describing one’s emotions, are elevated in depression and anxiety, and fluctuate across adolescence in a gender-specific manner. This study investigated changes in alexithymia across adolescence, and explored the potential role of alexithymia in the development of depression and anxiety, separately for females and males. Accordingly, 140 adolescents aged 11 to 21 years (77 female) completed self-report measures of alexithymia, depression and anxiety, and pubertal development. For females alone, pubertal maturation was associated with alexithymic traits (specifically difficulties identifying and describing feelings), as well as symptoms of depression and anxiety. After accounting for alexithymia, the relationship between puberty and depression and anxiety was absent or reduced in females. Thus, alexithymic traits may have differential consequences for males and females, and possibly contribute towards increased depression and anxiety symptoms in females during adolescence. We propose that developmental changes in alexithymia should be considered when studying the onset and development of internalizing psychological disorders during adolescence.

Relational Aggressiveness in Adolescence: Relations With Emotional Awareness and Self-Control

Involvement in relationally aggressive conduct is an important contributor to maladaptive functioning in both childhood and adulthood. Decreased emotional awareness and impairments of self-control are risk factors for relational aggressiveness, while emotional awareness can also be treated as an important prerequisite for proper self-control. The aim of the study was to examine the associations between dimensions of emotional awareness (attention to emotions and emotional clarity), self-control, and relational aggressiveness. Self-control was also examined as a mediating variable between emotional awareness and relational aggressiveness. Self-report measures of trait meta-mood, alexithymia, self-control, and relational aggressiveness were completed by 214 adolescents (129 females), aged 15–23. The confirmatory factor analysis confirmed two factors of emotional awareness: (1) inattention to emotions (reflecting low attention to emotions and externally oriented thinking) and (2) a lack of emotional clarity (reflecting difficulties in identifying emotion, difficulties in describing emotion, and low clarity of emotion). Self-control and mood repair ability inversely correlated with proactive and reactive relational aggressiveness, whereas the clarity component of the meta-mood trait only inversely predicted reactive relational aggressiveness. Structural equation modeling (SEM) showed that direct relationships between inattention to emotions and relational aggressiveness, as well as between lack of emotional clarity and relational aggressiveness were non-significant. Nevertheless, a lack of emotional clarity was indirectly and significantly associated with relational aggressiveness through decreased self-control.

Mindfulness, Alexithymia, and Empathy Moderate Relations Between Trait Aggression and Antisocial Personality Disorder Traits

Antisocial personality disorder (ASPD) has long been described focusing exclusively on behavioral features, like aggression. Although the role of mentalizing for aggression is well established, research on the role of mentalizing in ASPD remains limited. The present study examined the independent and interactive effects of mentalizing abilities and aggression in predicting ASPD traits in a violent male offender sample (N = 403). Participants completed self-report measures of ASPD traits, and a comprehensive assessment of mentalizing skills including measures of mindfulness, empathy, and alexithymia. Above and beyond the main effect of aggression, mindfulness, alexithymia, and empathy significantly explained an incremental amount of variance in ASPD traits in separate regression analyses. Further, mindfulness, alexithymia, and empathy significantly interacted with aggression in predicting ASPD scores. Findings suggest that among offenders with better mentalizing, aggression was significantly more strongly related to ASPD traits, indicating that at higher levels of mentalizing, only participants who also had higher levels of aggression scored higher on ASPD traits. Conversely, among offenders with poorer mentalizing, the positive association between aggression and ASPD traits was significantly weaker, indicating that poor mentalizing alone was sufficient to have high levels of ASPD traits (and aggression). Findings suggest that in some instances, mentalizing may not have a protective role on ASPD in the presence of very high levels of aggression. However, among offenders with poor mentalizing, treatments targeting aggression may not be successful in reducing ASPD traits. Interventions that aim at improving mentalizing may ultimately be more effective to treat aggression and ASPD among offenders.

Relationship between BMI and emotion-handling capacity in an adult Finnish population: The Northern Finland Birth Cohort 1966

BackgroundAlexithymia, a difficulty in identifying and expressing emotions, has been associated with obesity and eating disorders in small-scale cross-sectional studies. Here, we assess the relationship between body mass index (BMI) and alexithymia in a large cohort of free-living Finnish adults over a 15-year period.MethodsParticipants were drawn from the Northern Finnish Birth Cohort 1966 (NFBC1966). The 20-Item Toronto Alexithymia Scale (TAS-20) was used as a measure of alexithymia and was completed at the age of 31 years (31y: n = 4841), and 46 years (46y: n = 5404). BMI was recorded at both time points. Where data at both time points were available (n = 3274), the relationship between changes in BMI and TAS-20 over this time period was also investigated.ResultsBMI was significantly and positively associated with TAS-20 score (p<0.0001, both at 31 years and at 46 years of ages). The association remained statistically significant after adjustment for potential confounders (sex, marital status and several socio-economic indicators). In individuals who experienced the greatest change in BMI (in either direction) over the 15-year period, there was a modest mean increase in TAS-20 score.ConclusionsOur data revealed that TAS-20 score was correlated with and co-varied with body mass status. We suggest that future clinical research should consider the role of alexithymia in obesity. Further investigation of this relationship is warranted to ensure that the needs of obese subjects with undiagnosed alexithymia are considered in the design of weight management programmes.

Alexithymia mediates the relationship between interoceptive sensibility and anxiety.

A number of empirical and theoretical reports link altered interoceptive processing to anxiety. However, the mechanistic understanding of the relationship between the two remains poor. We propose that a heightened sensibility for interoceptive signals, combined with a difficulty in attributing these sensations to emotions, increases an individual’s vulnerability to anxiety. In order to investigate this, a large sample of general population adults were recruited and completed self-report measures of interoceptive sensibility, trait anxiety and alexithymia. Results confirmed that the positive association between interoceptive sensibility and trait anxiety was partially mediated by alexithymia, such that those most at risk for clinically significant levels of trait anxiety have both significantly higher levels of interoceptive sensibility and alexithymia. A subsequent factor analysis confirmed the independence of the three measures. Altered interoceptive processing in combination with alexithymia, increased the risk for anxiety above and beyond altered interoceptive processing alone. We suggest that a heightened sensibility for interoceptive signals, combined with a difficulty in attributing these sensations to emotions, leaves these sensations vulnerable to catastrophizing interpretation. Interventions that target the attribution of bodily sensations may prove valuable in reducing anxiety.

Social Interaction Anxiety, Alexithymia, and Drinking Motives in Australian University Students

ABSTRACTIn young adults at university, social interaction anxiety has been linked to elevated risk of alcohol-related problems, as has alexithymia. The present study sought to assess whether social interaction anxiety is, like alexithymia, associated with the primary motive of drinking to cope with negative affect. There were 126 undergraduates (76 females, 50 males), aged 18–25 years, who were recruited from two southeast Queensland universities to complete validated self-report measures of problematic drinking, alexithymia, drinking motives, and social interaction anxiety. As predicted, social interaction anxiety was positively related to problematic drinking and coping motives for drinking. Alexithymia mediated the relationship of social interaction anxiety with coping motives. Findings were consistent with a developmental hypothesis of the links between social anxiety, alexithymia, and drinking motives. Given the cross-sectional design of the current study, longitudinal research is ultimately needed to confirm such interpretations of alexithymia and alcohol use among socially anxious young adults at university.

Using Overt and Covert Items in Self-Report Personality Tests: Susceptibility to Faking and Identifiability of Possible Fakers.

Self-report personality tests widely used in clinical, medical, forensic, and organizational areas of psychological assessment are susceptible to faking. Several approaches have been developed to prevent or detect faking, which are based on the use of faking warnings, ipsative items, social desirability scales, and validity scales. The approach proposed in this work deals with the use of overt items (the construct is clear to test-takers) and covert items (the construct is obscure to test-takers). Covert items are expected to be more resistant to faking than overt items. Two hundred sixty-seven individuals were presented with an alexithymia scale. Two experimental conditions were considered. Respondents in the faking condition were asked to reproduce the profile of an alexithymic individual, whereas those in the sincere condition were not asked to exhibit a particular alexithymia profile. The items of the scale were categorized as overt or covert by expert psychotherapists and analyzed through Rasch models. Respondents in the faking condition were able to exhibit measures of alexithymia in the required direction. This occurred for both overt and covert items, but to a greater extent for overt items. Differently from overt items, covert items defined a latent variable whose meaning was shared between respondents in the sincere and faking condition, and resistant to deliberate distortion. Rasch fit statistics indicated unexpected responses more often for respondents in the faking condition than for those in the sincere condition and, in particular, for the responses to overt items by individuals in the faking condition. More than half of the respondents in the faking condition showed a drift rate (difference between the alexithymia levels estimated on the responses to overt and covert items) significantly larger than that observed in the respondents in the sincere condition.

Emotion regulation and aggression: The incremental contribution of alexithymia, impulsivity, and emotion dysregulation facets.

Objective: Prior research has long emphasized the role of alexithymia and impulsivity to explain aggressive tendencies. Recently, a growing body of research seems to support the relevance of the broader construct of emotion dysregulation to understand aggression. The present study was the first to comprehensively examine the relative contribution of, and the mechanisms linking alexithymia, impulsivity, and emotion dysregulation in predicting aggression dimensions. Method: Male violent offenders (N = 221) and community participants (N = 245) completed multifaceted self-report measures of alexithymia, impulsivity, emotion dysregulation, and aggression. Regression analyses tested the independent contribution of each facet on aggression dimensions. Bootstrap analyses examined the indirect effect of alexithymia on aggression through emotion dysregulation and impulsivity. Results: Offenders reported higher levels of difficulties identifying feelings, emotional nonacceptance, physical aggression, and hostility. Difficulties in identifying and describing feelings, and motor and attentional impulsivity, explained unique variance in physical aggression, anger, and hostility in both samples, and also in verbal aggression among community participants. In both samples, negative urgency and emotional nonacceptance explained additional variance in aggression dimensions above and beyond the influence of alexithymia and impulsivity. Emotion dysregulation and impulsivity mediated the relation between alexithymia and aggression in both samples, with emotion dysregulation demonstrating a relatively stronger effect. Conclusions: Findings emphasize the unique relevance of alexithymia, impulsivity, and emotion dysregulation facets in explaining aggressive tendencies. Clinical implications include the importance of focusing on emotion regulation skills-such as accepting emotions and do not act on them-to reduce aggression tendencies.

Emotional intelligence, alexithymia, stress, and people’s reasons for listening to music

The present study investigated the relationship between people’s reasons for listening to music, trait emotional intelligence, and alexithymia whilst also controlling for the effect of participants’ gender, age, and perceived stress levels. In keeping with previous research, initial findings indicated that emotionally intelligent individuals were less likely to use music to relieve and alleviate negative moods, whilst those who had high scores on a measure of alexithymia were more likely to use music for the same reasons. However, when the effects of gender, age, and perceived stress were controlled for, these relationships were no longer significant and previously non-significant relationships between trait emotional intelligence and using music to manipulate arousal and to reminisce about the past were found to be significant. Together these findings suggest that emotional intelligence is related to the reasons why people listen to music but not in the way that previous research had suggested, and the apparent links between emotional intelligence and mood management might be better explained by the stress experienced by participants at the time of questioning.

The psychometric assessment of alexithymia: Development and validation of the Perth Alexithymia Questionnaire

Alexithymia is a trait comprising people's ability to focus attention on and accurately appraise their own emotions. Its assessment is of clinical interest because people who have difficulty processing their negative and positive emotions are more vulnerable to developing psychopathology symptoms, however, existing alexithymia measures cannot comprehensively assess the construct across both negative and positive emotions. In this paper, we attempt to remedy these measurement limitations by developing and validating a new 24-item self-report measure, the Perth Alexithymia Questionnaire (PAQ), which is based on the attention-appraisal model of alexithymia. In Study 1, our confirmatory factor analyses in a sample of 231 adults suggested that the PAQ had a factor structure consistent with its theoretical basis; it could separately measure all components of the construct and do so across negative and positive emotions. All subscale and composite scores had high internal consistency reliability. Study 2 (N = 748) replicated these findings with respect to the PAQ's factor structure and internal consistency reliability, and statistical comparisons with measures of psychopathology and emotion regulation supported the PAQ's concurrent and discriminant validity. Our data therefore suggest that the PAQ has strong psychometric properties as a measure of alexithymia. Clinical and research applications are discussed.

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

Background: Alexithymia and emotional awareness may be considered overlapping constructs and both have been shown to be related to psychological and emotional well-being. However, it is not clear how the constructs relate to each other empirically or if they may overlap more or less in different populations. The aim of this review was therefore to conduct a meta-analysis of correlations between the most commonly used measures of alexithymia (i.e., the self-report instrument Toronto Alexithymia Scale; TAS-20) and emotional awareness (i.e., the observer-rated instrument Level of Emotional Awareness Scale; LEAS) and to explore potential moderators of their relationship.Methods: Electronic databases were searched for studies published until the end of February 2018. Study samples were coded as medical conditions, psychiatric disorders and/or healthy controls and sample mean age and gender distribution were extracted. Correlations between the TAS-20 and the LEAS were subjected to a random effect of meta-analysis and moderators were explored in subgroup analyses and meta-regressions. Publication bias was considered.Results: 21 studies reporting on 28 independent samples on correlation analysis were included, encompassing a total of 2857 subjects (57% women). The aggregated correlation between TAS-20 and LEAS was r = −0.122 (95% CI [−0.180, −0.064]; Z = −4.092; p < 0.001), indicating a significant, but weak, negative relationship between the measures. Heterogeneity was moderate, but we found no indication of significant differences between patients with medical conditions, psychiatric disorders or healthy controls, nor that mean age or percentage of female subjects moderated the relationship. The overall estimate became somewhat weaker after adjusting for possible publication bias.Conclusions: Our results indicate that TAS-20 and LEAS measure different aspects of emotional functioning. The small overlap suggests that alexithymia and emotional awareness are distinct constructs of emotional well-being. Clinicians need to assess both aspects when considering treatment options for individual patients. Moreover, from the clinical standpoint, an easy reliable and valid way of measuring emotional awareness is still needed. More research should be focus on the differences between alexithymia and emotional awareness in specific conditions, but also how to integrate self-report instrument and observed based measures in a clinical situation.

Validation of the Reading the Mind in the Eyes Test in a healthy Spanish sample and women with anorexia nervosa

ABSTRACTIntroduction: The aim of this study was to build a Spanish version of the Reading the Mind in the Eyes Test (RMET) including limited time of response and an integrated glossary, and to test its validity.Methods: A total of 433 university students (121 men and 350 women) and 38 anorexic women completed the RMET and other related measures of empathy and alexithymia. The results of the Parallel Analysis suggested a unidimensional structure for 19 items, which was verified through a Confirmatory Factor Analysis.Results: Similarly to other research, this factor had a low reliability (α = .56, ρ = .59); however, regarding validity, the total score of the instrument showed positive correlations with empathy and negatives with alexithymia. Furthermore, healthy females were superior to males in RMET, and to anorexic women; but no significant differences appeared between healthy men and the anorexic group.Conclusion: This study confirms the validity of the test and permits a relatively short and inexpensive means of administration in large samples of adults. Besides, it suggests the necessity of assessing and treating the theory of mind in anorexic women.

Effectiveness of emotional skills training for patients with anorexia nervosa with autistic symptoms in group and individual format.

The aim of this study was to examine the effectiveness of CREST interventions in individual and group formats for adult anorexia nervosa. Furthermore, this study also aims to analyse whether patients with high levels of autistic symptoms respond differently. Participants' self-report measures were taken before and after individual and group interventions (N=66 and N=62, respectively). Mixed effects analysis was used to analyse overall response to both formats and assess interaction with autism symptoms. Significant improvements were observed for patients' alexithymia in individual format, and motivation increased for participants in both interventions. Significant interactions were observed between alexithymia, social anhedonia, and autism symptoms in individual format and alexithymia in group format. No interactions between autism and time were observed for either format. CREST in both formats offers participants improvements in social-emotional and motivational domains. Patients with high levels of autism symptoms also score high on both social anhedonia and alexithymia measures, but this does not affect their response to treatment.

Relations of mindfulness facets with psychological symptoms among individuals with a diagnosis of obsessive-compulsive disorder, major depressive disorder, or borderline personality disorder.

To explore differences in mindfulness facets among patients with a diagnosis of either obsessive-compulsive disorder (OCD), major depressive disorder (MDD), or borderline personality disorder (BPD), and healthy controls (HC), and their associations with clinical features. One hundred and fifty-three patients and 50 HC underwent a clinical assessment including measures of mindfulness (Five Facets Mindfulness Questionnaire - FFMQ), psychopathological symptoms (Symptom Check List-90-R), dissociation (Dissociative Experience Scale), alexithymia (Alexithymia Scale 20), and depression (Beck Depression Inventory-II). Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were performed to assess differences in mindfulness scores and their associations with clinical features. The three diagnostic groups scored lower on all mindfulness facets (apart from FFMQobserving) compared to the HC group. OCD group had a significant higher FFMQ total score (FFMQ-TS) and FFMQacting with awareness compared to the BPD group, and scored higher on FFMQdescribing compared to BPD and MDD groups. The scores in non-judging facet were significantly lower in all the three diagnostic groups compared to the HC group. Interestingly, higher FFMQ-TS was inversely related to all psychological measures, regardless of diagnostic group. Deficits in mindfulness skills were present in all diagnostic groups. Furthermore, we found disease-specific relationships between some mindfulness facets and specific psychological variables. Clinical implications are discussed. The study showed deficits in mindfulness scores in all diagnostic groups compared to a healthy control group. Overall, mindfulness construct has a significantly negative association with indexes of global distress, dissociative symptoms, alexithymia, and depression. Mindfulness-based interventions in clinical settings should take into account different patterns ofmindfulness skills and their impact on disease-specific maladaptive cognitive strategies or symptomatology.

Alexithymia as a potential source of symptom over-reporting: An exploratory study in forensic patients and non-forensic participants.

The traditional interpretation of symptom over-reporting is that it indicates malingering. We explored a different perspective, namely that over-reporting of eccentric symptoms is related to deficits in articulating internal experiences (i.e., alexithymia). Given that alexithymia has been linked to sleep problems and that fatigue may fuel inattentive responding to symptom lists, we administered measures of alexithymia (TAS-20) and symptom over-reporting (SIMS), but also sleep quality (SLEEP-50) to forensic psychiatric outpatients (n = 40) and non-forensic participants (n = 40). Forensic patients scored significantly higher on all three indices than non-forensic participants. In the total sample as well as in subsamples, over-reporting correlated positively and significantly with alexithymia, with rs being in the 0.50-0.65 range. Sleep problems were also related to over-reporting, but in the full sample and in the forensic subsample, alexithymia predicted variance in over-reporting over and above sleep problems. Although our study is cross-sectional in nature, its results indicate that alexithymia as a potential source of over-reporting merits systematic research.

Childhood maltreatment is associated with attachment insecurities, dissociation and alexithymia in bipolar disorder

Child maltreatment is a public health issue that is a well-established risk factor for many psychological conditions, including bipolar disorder. The current study is one of the first to investigate associations among child maltreatment, dissociative symptomatology, alexithymia, anxiety, depression, and attachment insecurities. 40 patients with bipolar disorder-I and 40 healthy subjects matched for age, gender, and education participated in the study. The Dissociative Experiences Scale (DES), Somatoform Dissociation Questionnaire (SDQ), Childhood Trauma Questionnaire (CTQ-28), Toronto Alexithymia Scale (TAS-20), Depression Anxiety Stress Scale (DASS-21), and Experiences in Close Relationships-Revised (ECR-R) were completed by participants. In comparison to control participants, patients with bipolar disorder-I reported significantly more frequent abusive experiences in childhood, higher levels of attachment insecurities, more severe pathological and somatoform dissociation, as well as higher scores on measures of alexithymia, anxiety, depression and psychological stress. Reports of psychopathology among first-degree relatives (OR = 102.169, 95%IC = 4.596–2271.255; P < 0.01) and childhood emotional trauma (OR = 1.032; 95%CI = 0.782–1.363, P = 0.05) significantly contributed to bipolar disorder-I diagnosis. In contrast, absorption was negatively associated with bipolar illness (OR = 0.852; 95% CI = 0.747–0.973, P < 0.05). Our results showed significant associations between childhood trauma exposure and risk of bipolar disorder. Moreover, the results demonstrate that emotional abuse exposure predicts bipolar illness.

Alexithymia according to Bucci's multiple code theory: A preliminary investigation with healthy and hypertensive individuals.

To evaluate the relation between alexithymia and Referential Activity (RA), a linguistic measure of the process by which non-verbal emotional experience is connected to language. The 20-Item Toronto Alexithymia Scale (TAS-20) and the Toronto Structured Interview for Alexithymia (TSIA) were administered to 20 postgraduate students and 15 outpatients with hypertension. The Weighted Referential Activity Dictionary (WRAD) and other linguistic measures (Reflection, Disfluency, and Somatic Sense) were applied to texts derived from the TSIA using the Discourse Attributes Analysis Program (DAAP). Multiple linear regressions performed in the whole sample showed a relation between TSIA scores and Somatic Sense. Comparing the two groups, hypertensive subjects yielded higher scores on the TSIA than the young adult sample; no differences in DAAP measures emerged. A significant negative correlation was found between the TAS-20 Difficulty Describing Feelings score and the DAAP measure of references to body activations (Somatic Sense) both in the young adult sample and in hypertensives. In the young adult sample, negative relations emerged between different TSIA factors, WRAD score, and Somatic Sense; a positive relation with fragmented speech (Disfluency) and use of rationalization (Reflection) was also found. In hypertensive subjects, using the TSIA, a negative correlation between alexithymia and Somatic Sense and a positive correlation between alexithymia and the Mean High WRAD (a measure of intensity of engagement during the speech) were found. The TSIA seems to be a more adequate instrument than the TAS-20 to explore relations between alexithymia and RA. Results appear to suggest a complex, nonlinear relation between alexithymia and RA, presumably influenced by subject-specific characteristics. A relation between alexithymia and RA has been proposed on theoretical grounds, but there has been minimal empirical investigation. This was the first study to employ both a self-report measure and a structured interview for measuring alexithymia in relation to RA. The results of this study suggest a complex, nonlinear relation between alexithymia and RA; this finding is essentially obtained with the structured interview measure of alexithymia. This relation is presumably influenced by subject-specific characteristics.

I can feel my heartbeat: Dancers have increased interoceptive accuracy.

Interoception is the process of perceiving afferent signals arising from within the body including heart rate (HR), gastric signals, etc., and has been described as a mechanism crucially involved in the creation of self-awareness and selfhood. The heartbeat perception task is a tool to measure individuals' interoceptive accuracy (IAcc). IAcc correlates positively with measures of self-awareness and with attributes including emotional sensitivity, empathy, prosocial behavior, and efficient decision making. IAcc is only moderate in the general population, and attempts to identify groups of people who might have higher IAcc due to their specific training (e.g., yoga, meditation) have not been successful. However, a recent study with musicians suggests that those trained in the arts might exhibit high IAcc. Here, we tested IAcc in 20 professional dancers and 20 female control participants on a heartbeat perception task. Dancers had a higher IAcc, and this effect was independent of their lower heart rates (a proxy measure of physical fitness), counting ability, and knowledge about HR. An additional between-groups analysis after a median split in the dancer group (based on years of dance experience) showed that junior dancers' IAcc differed from controls, and senior dancers' IAcc was higher than both junior dancers and controls. General art experience correlated positively with IAcc. No correlations were found between IAcc and questionnaire measures of empathy, emotional experience, and alexithymia. These findings are discussed in the context of current theories of interoception and emotion-highlighting the features of arts training that might be related to IAcc.

Optimizing trauma-informed intervention for intimate partner violence in veterans: The role of alexithymia

Recent research supports the efficacy of Strength at Home-Men's Program (SAH-M), a trauma-informed group intervention designed to reduce use of intimate partner violence (IPV) in veterans (Taft, Macdonald, Creech, Monson, & Murphy, 2016). However, change-processes facilitating the effectiveness of SAH-M have yet to be specified. Alexithymia, a deficit in the cognitive processing of emotional experience characterized by difficulty identifying and distinguishing between feelings, difficulty describing feelings, and use of an externally oriented thinking style, has been shown to predict PTSD severity and impulsive aggression; however, no studies have investigated the relationship between alexithymia and IPV. As such, the current study examined the role of improvements in alexithymia as a potential facilitator of treatment efficacy among 135 male veterans/service members, in a randomized control trial SAH-M. After an initial assessment including measures of IPV and alexithymia, participants were randomized to an Enhanced Treatment as Usual (ETAU) condition or SAH-M. Participants were assessed three and six months after baseline. Results demonstrated a statistically significant association between alexithymia and use of psychological IPV at baseline. Moreover, participants in the SAH-M condition self-reported significantly greater reductions in alexithymia over time relative to ETAU participants. Findings suggest that a trauma-informed intervention may optimize outcomes, helping men who use IPV both limit their use of violence and improve deficits in emotion processing.
