The influence of alexithymia and music on the incidental memory for emotion words

Alexithymia is a multifaceted personality construct which encompasses difficulties in identifying and expressing feelings along with an externally oriented cognitive style. We investigated whether congruent vs. incongruent emotional musical priming (happy and angry music) during encoding would moderate the effects of alexithymia on recognition rates. We found that high alexithymia scorers recognized fewer joy and anger words than low scorers. Angry music decreased recognition rates in high alexithymia scorers compared to low alexithymia scorers. The congruency and incongruency effects between music and words depended on alexithymia level. The anger deficit in high alexithymia scorers and the possible support provided by happiness cues are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Criterion validity of Bermond-Vorst Alexithymia Questionnaire-20 Form B: a study of 63 alcoholic subjects

The aim of the study was to set alexithymia cutoff scores on the 20-item Bermond-Vorst Alexithymia Questionnaire-20 Form B. Alexithymia is a clinical construct describing individuals who have difficulty identifying and reporting their specific emotions. 63 subjects meeting the DSM-IV criteria for alcohol dependence completed the questionnaire and the 20-item Toronto Alexithymia Scale. Using cutoff scores for the latter, subjects were divided into alexithymic and nonalexithymic subgroups. Taking into account the sensitivity, specificity, and predictive positive value, several potential Bermond-Vorst questionnaire scores were tested. Using the Younden formula (Sensitivity+ Specificity-1), score of 52 was the most appropriate cutoff score for the Bermond-Vorst-20 to indicate the presence of alexithymia in these male alcoholics.     

Psychological profiles and emotional regulation characteristics of women engaged in risk-taking sports

We investigated the psychological profiles and emotional regulation characteristics of women involved in risk-taking sports. The research sample (N=180) consisted of three groups of women engaged in: (1) non-risk sports (N=90); (2) risk-taking sports for leisure purposes (N=53); or (3) risk-taking sports as professionals (N=37). Each participant completed five questionnaires, the Sensation Seeking Scale, the Bem Sex Role Inventory, the Barratt Impulsiveness Scale, Risk & Excitement Inventory, and the Toronto Alexithymia Scale. The results revealed significant differences between the groups' profiles. Of particular interest are the differences that exist between the profiles of Group 2 (escape profile, masculine gender identity, and high scores on sensation seeking, impulsivity, alexithymia) and Group 3 (compensation profile, androgynous gender identity, average score on sensation seeking, and low scores on impulsivity, alexithymia). We propose that the professional woman might be considered a model for preventing destructive risk-taking behaviors.     

An application of item response theory to alexithymia assessment among abstinent alcoholics.

An item response theory (IRT) model identified three dimensions assessed by the Toronto Alexithymia Scale (TAS) in a sample of 130 male applicants for inpatient care at a Veterans Administration (VA) medical center alcoholism treatment program. A unidimensional solution did not capture all of alexithymia's theoretical features. Subjects with lower alexithymia scores gave positive responses to items tapping emotional awareness deficits; only those with higher alexithymia scores gave positive responses to items tapping external, operative cognitive style. Thus, a total TAS score may not represent alexithymia accurately in substance-abusing patient populations.     

Association between alexithymia, neuroticism, and social desirability scores among Italian graduate students

An inverse correlation between social desirability and alexithymia has been observed in undergraduate students in Japan and Australia. It is not clear how this association is influenced by the personality dimension of neuroticism. This study examined the association of scores on social desirability with those on alexithymia controlled for neuroticism, in a sample of 111 Italian graduate students, with age range of 24 to 58 years. Students completed the Eysenck Personality Questionnaire (short form) and the Toronto Alexithymia Scale-20 (TAS-20). Social desirability scores inversely correlated with TAS-20 total scores, neuroticism scores, and the TAS-20 subscale, Difficulty identifying feelings. Neuroticism directly correlated with TAS-20 total score, Difficulty identifying feelings, and Difficulty describing feelings. Students with higher alexithymia and neuroticism scores seem to present themselves in less socially desirable ways. The correlation of social desirability with alexithymia was moderated by higher neuroticism scores.     

Alexithymia in schizophrenia: an exploratory study.

This study assessed a relationship between alexithymia and schizophrenia suggested by reports based on small samples of patients. Here, 50 outpatients with a diagnosis of paranoid schizophrenia were compared with 50 pair-matched healthy subjects. Alexithymia was measured by the Polish version of the Toronto Alexithymia Scale-20. The mean total score was significantly higher in the schizophrenia group (M = 52.3, SD = 13.47) than in the healthy controls (M = 45.8, SD = 11.39, p < .02). This replicates earlier findings showing that a group of patients with paranoid schizophrenia have higher scores on alexithymia scales than healthy controls. There seems a need for a comprehensive examination of relations between alexithymia and other concepts denoting pathology of affect in schizophrenia.     

On the Relationship Between Interoceptive Awareness and Alexithymia: Is Interoceptive Awareness Related to Emotional Awareness?

Interoceptive awareness (IA) is associated with emotional experience, the processing of emotional stimuli, and activation of brain structures that monitor the internal visceral and emotional state of the organism. Alexithymia is characterized by difficulties in identifying and describing one's emotions and externally oriented thinking (EOT) and reflects impairments in emotional awareness and the regulation of emotions. This study examined the relationship between alexithymia and IA in a healthy population of N=155 persons. A well-validated heartbeat perception task to measure interoceptive awareness, the Toronto Alexithymia Scale (TAS-20) and a depression questionnaire (BDI-2) were administered to 88 women and 67 men. IA was inversely associated with all features of alexithymia in the whole sample. When considering sex differences, IA turned out to be a relevant negative predictor for the EOT subscale only in men. This large sample investigation in a nonclinical population indicates that IA represents a relevant negative predictor for alexithymia.     

Observation of couple interactions: Alexithymia and communication behaviors

Alexithymia is conceptualized as a deficit of the cognitive aspect of an emotional response. Alexithymia has been associated with various relational difficulties, but few studies have investigated couple relationships. The present study addresses the imperative need for the advancement of knowledge regarding the impact of alexithymia on couple relationships and, more specifically, on communication behaviors. One hundred and fifty participants (75 couples) completed the Toronto Alexithymia Scale (TAS-20) and their interactions in the laboratory were coded using the Interactional Dimensions Coding System (IDCS). Actor–partner effects were investigated using Multi-level analyses. For women, no relationship was found between self-alexithymia and communication behaviors for self or partner. For men, alexithymia was found to be associated with their own hostility, but also with their partner’s hostility, withdrawal and communication skills. The results are discussed through a social learning perspective.     

Event-related brain potentials reveal differences in emotional processing in alexithymia

ABSTRACT

The inability to recognise and describe emotions in the self is known as Alexithymia. In the present study we used event-related potentials (ERPs) to examine the locus of processing emotional differences in alexithymia. We tested men, both those scoring high (score?>?61) and controls who scored low (score?<?51) on the Toronto Alexithymia Scale-20 on an emotional face discrimination task. We assessed three ERP components: P1 (an index of early perceptual processing), N170 (an index of early facial processing) and P3 (an index of late attentional suppression). While controls showed a stronger P3 effect for angry faces relative to happy and neutral faces, Alexithymic men showed no significant differences in P3 across emotions. Alexithymic men showed delayed P1 and N170 amplitudes compared to controls. These results suggest that the locus of processing differences between alexithymic men and controls occur both early in perceptual processing and later in conscious processing.     

Different subgroups of high-scorers on the TAS-20 based on the big five personality traits

We investigated whether it was possible to obtain a consistent representation of the alexithymia trait by using the twenty-item Toronto Alexithymia Scale (TAS-20). TAS-20 and the NEO-Five Factor Inventory were administered to nonclinical participants (N = 2188). The results of hierarchical cluster analysis and a two-way analysis of variance indicated two subgroups with high scores on the TAS-20. One group had difficulty identifying feelings and high neuroticism; the other had a high externally oriented cognitive style and low openness to experience. These results suggest that the total score on the TAS-20 should not be considered a uni-dimensional measure of alexithymia.     

Alexithymia is not related to tolerance for cold pressor pain

To test the hypothesis that higher scores on alexithymia are associated with reduced tolerance for cold pressor pain, 116 college undergraduates completed the Toronto Alexithymia Scale-20 of Bagby, Parker and Taylor and engaged in the cold pressor test. Their alexithymia scores were not associated with tolerance for cold pressor pain, suggesting that individuals scoring high on alexithymia do not show a general hypersensitivity to a cold stimulus.     

TAS-20 alexithymia in obesity, and its links to personality

We studied the association between alexithymia (20-item Toronto Alexithymia Scale, TAS-20) and obesity, and also assessed the construct validity of the TAS-20 in terms of personality dimensions in obese patients. The TAS-20 and its subscales were analysed for their correlations with the NEO Personality Inventory - Revised (NEO PI-R) in an obese sample of 259 patients. Obesity was associated with higher scores on the TAS-20 than a Swedish reference sample. Obese men furthermore scored higher on Externally Oriented Thinking than the obese women. TAS-20 scores correlated with elevated Neuroticism and lower levels of Extraversion and Openness, in agreement with most previous research, but also somewhat unexpectedly with lower Conscientiousness and for women also with lower Agreeableness. The TAS-20 subscales showed divergent associations with personality variables, largely in accordance with previous findings. The associations were more prominent for the women, and some gender-specific patterns not previously reported were also revealed.     

Alexithymia--state or trait?

Alexithymia refers to a specific disturbance in emotional processing that is manifested by difficulties in identifying and verbalizing feelings and a tendency to focus on and amplify the somatic sensations that accompany emotional arousal. Alexithymia is conceptualized both as an affect-deficit disorder and a continuous personality variable. The main purpose of the present study was to investigate the stability levels of alexithymia with regard to changes in emotional distress levels caused by university exams. We tested 20 university students at four different times, before and after the exams. Alexithymic features and self-reported emotional distress (trait anxiety and physical symptoms) were measured. Whereas emotional distress measures changed significantly during the diverse phases, the level of alexithymia remained unchanged. We therefore conclude that alexithymia represents a constant trait.     

Effects of facial expressions on visual short-term memory in relation to alexithymia traits

We examined dysfunctional memory processing of facial expressions in relation to alexithymia. Individuals with high and low alexithymia, as measured by the Toronto Alexithymia Scale (TAS-20), participated in a visual search task (Experiment 1A) and a change-detection task (Experiments 1B and 2), to assess differences in their visual short-term memory (VSTM). In the visual search task, the participants were asked to judge whether all facial expressions (angry and happy faces) in the search display were the same or different. In the change-detection task, they had to decide whether all facial expressions changed between successive two displays. We found individual differences only in the change-detection task. Individuals with high alexithymia showed lower sensitivity for the happy faces compared to the angry faces, while individuals with low alexithymia showed sufficient recognition for both facial expressions. Experiment 2 examined whether individual differences were observed during early storage or later retrieval stage of the VSTM process using a single-probe paradigm. We found no effect of single-probe, indicating that individual differences occurred at the storage stage. The present results provide new evidence that individuals with high alexithymia show specific impairment in VSTM processes (especially the storage stage) related to happy but not to angry faces.     

Finding words for feelings: The relationship between personality disorders and alexithymia

This study examined whether personality disorders (PDs) are associated with alexithymic features at varying levels of comorbid psychopathology distress. 167 psychiatric outpatients completed the Toronto Alexithymia Scale (TAS) and the General Severity Index (GSI) of the SCL90-revised. Bootstrapping analyses were performed to test whether the PD/alexithymia relationship was moderated by psychopathology distress (GSI). The overall number of PD criteria was associated with cognitive aspects of alexithymia (i.e., Externally Oriented Thinking, EOT) only at low/moderate levels of distress. Borderline criteria predicted EOT only when distress was low, while avoidant and dependent criteria were independently related with EOT. No association was found between other PDs and alexithymia facets. Thus, within clinical samples the alexithymia/PD association is mainly explained by comorbid psychopathology; however, individuals with avoidant, dependent and borderline features might have a specific difficulty with focusing on internal reality, even when their current symptom distress is low.     

Alexithymia among empirically derived subgroups of chronic back pain patients

A seeded cluster analysis procedure was applied to the Minnesota Multiphasic Personality Inventory (MMPI) profiles of 102 male and 63 female back-pain patients. For both men and women, the resulting subgroups were found to correspond closely to similar subgroups obtained in several previous investigations. New data on the psychometric properties of the MMPI Alexithymia scale (Kleiger & Kinsman, 1980) are presented. Significant differences in alexithymia among empirically derived MMPI subgroups were found in the male sample only.

Alexithymia and risk preferences: Predicting risk behaviour across decision domains

Risk‐taking is a critical health factor as it plays a key role in several diseases and is related to a number of health risk factors. The aim of the present study is to investigate the role of alexithymia in predicting risk preferences across decision domains. One hundred and thirteen participants filled out an alexithymia scale (Toronto Alexithymia Scale—TAS‐20), impulsivity and venturesomeness measures (I7 scale), and—1 month later—the Cognitive Appraisal of Risky Events (CARE questionnaire). The hierarchical regression analyses showed that alexithymia positively predicted risk preferences in two domains: aggressive/illegal behaviour and irresponsible academic/work behaviour. The results also highlighted a significant association of the alexithymia facet, externally oriented thinking (EOT), with risky sexual activities. EOT also significantly predicted aggressive/illegal behaviour and irresponsible academic/work behaviour. The alexithymia facet, Difficulty Identifying Feelings, significantly predicted irresponsible academic/work behaviour. The results of the present study provide interesting insights into the connection between alexithymia and risk preferences across different decision domains. Implications for future studies and applied interventions are discussed.
