Abstract
Autism spectrum disorder (ASD) is associated with differences in social communication, and these differences are related to trait emotional intelligence (TEI), alexithymia, and empathy. Autism is known to present differently in males and females, but research on sex differences in TEI, alexithymia, and empathy is largely relegated to non-autistic people. Therefore, the current research sought to explore individual relationships between autistic characteristics and TEI, alexithymia, and empathy, as well as the possible influence of sex in these relationships. In the current study, autistic and non-autistic adults reported on their autistic characteristics, TEI, alexithymia, and empathy. Based on previous research, it was hypothesized that more autistic characteristics would be associated with less TEI, more alexithymia, and less empathy, and that these relationships would be more prominent amongst males. More autistic characteristics were associated with greater challenges across the three areas of interest. However, only the relationship between TEI and autistic characteristics was moderated by sex, such that males demonstrated higher support needs related to TEI than females. Results from this analysis indicate that adults with more autistic characteristics, regardless of diagnostic status, demonstrate differences in TEI, alexithymia, and empathy. The current analysis may offer additional context to the evolving understanding of empathy and autism by suggesting that TEI and alexithymia could account for differences in empathy. Moreover, sex seems to play a role in the relationship between autistic characteristics and TEI such that differences are especially prominent for males.

Association between alexithymia and non-suicidal self-injury in psychiatric patients: the mediating role of self-esteem and the moderating role of emotional intelligence. J Psychiatr Res 2023; 162:57-64. [PMID: 37088044 DOI: 10.1016/j.jpsychires.2023.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 03/09/2023] [Accepted: 04/05/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Raffagnato's theory claims that if people have no words to express their emotions (alexithymia), they express themselves by venting or through non-suicidal self-injury (NSSI). However, these associations have not been confirmed in psychiatric patients. This study explored the relationship between alexithymia and NSSI in psychiatric patients and the potential underlying psychological mechanisms. METHODS This retrospective study involved face-to-face interviews with 449 outpatients consecutively recruited from West China Hospital. Alexithymia, self-esteem, NSSI, and emotional intelligence (EI) were measured. The moderating role of EI and the mediating role of self-esteem between alexithymia and NSSI were also explored. Logistic regressions were used to examine whether sociodemographic, clinical variables and alexithymia were independently associated with NSSI. RESULTS The DSM-5 NSSI disorder and alexithymia prevalences were found to be 32.5% and 45.2%. When the other covariables were controlled for, the alexithymic patients were found to be at increased odds (OR 2.76) of engaging in NSSI behaviors. These results confirmed the strong associations between alexithymia, low self-esteem, and NSSI risk. Lower EI was found to be related to the connections between alexithymia and NSSI. Except for the lower risk in anxiety patients, the risk of NSSI was similar for patients with other mental disorders, CONCLUSION: This study revealed the psychological mechanisms through which alexithymia increases the risk of NSSI. Therefore, to reduce NSSI risk, screening for alexithymia should be emphasized. Self-esteem as a targeted psychological intervention could also assist in mitigating the process from alexithymia to NSSI behaviors, and EI training for psychiatric patients could weaken the relationship between alexithymia and NSSI.

Empathy and the ability to experience one's own emotions modify the expression of blatant and subtle prejudice among young male adults. J Psychiatr Res 2021; 137:471-479. [PMID: 33798974 DOI: 10.1016/j.jpsychires.2021.03.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 03/02/2021] [Accepted: 03/05/2021] [Indexed: 01/10/2023]
Abstract
Prejudices can lead to discrimination, social exclusion, and violence particularly among young male adults. Previous findings suggest that the degree of holding prejudices is linked to low levels of empathy, while low levels of empathy have been associated with alexithymia, the inability to experience one's own feelings. We tested the hypothesis that the impact of a lack of empathy on reporting blatant and subtle prejudices is moderated by the inability to identify one's own feelings. In a sample of n = 136 young male adults aged 21 years (mean = 21.5 years; sd = 0.3), we conducted correlation and moderator analyses to determine possible relationships between prejudices, empathy, and alexithymia as assessed by self-report questionnaires. Prejudices were assessed by the Blatant and Subtle Prejudice Scale (BSPS), empathy was assessed by the German modified version of the Interpersonal Reactivity Index (IRI), and alexithymia by the 20-item Toronto Alexithymia Scale (TAS-20). Self-reported empathy levels were correlated with the strength of subtle and blatant prejudices. The moderation analyses revealed that the negative association between empathy and subtle prejudice increased with decreasing alexithymia. The negative association between empathy and blatant prejudice, on the other hand, was significant only for participants with low levels of alexithymia. These results suggest that empathy can limit the expression of blatant and to some degree also subtle prejudice when subjects are capable to identify their own feelings in a group of young males.

Abstract
The 20‐item Toronto Alexithymia Scale (TAS‐20) was developed in previous research to measure a general dimension of alexithymia with three inter correlated factors. These three factors reflect distinct facets of the alexithymia construct: (1) difficulty identifying feelings and distinguishing them from the bodily sensations of emotion, (2) difficulty describing feelings to others, and (3) an externally orientated style of thinking. This study tested the three‐factor model for the TAS‐20, using confirmatory factor analysis, in separate samples of young adults from Germany, Canada, and the United States. The previously established three‐factor model was found to be replicable in all three samples. In addition, the full TAS‐20 and its three factors demonstrated adequate internal reliability in all three samples. Although evaluation of the convergent, discriminant, and criterion validity of the TAS‐20 is required in diverse cultural groups, the present results provide evidence for the factorial validity and internal reliability of the TAS‐20.

Alexithymia as a possible specifier of adverse outcomes: Clinical correlates in euthymic unipolar individuals. J Affect Disord 2020; 263:428-436.

Abstract
BACKGROUND Alexithymia is a disabling condition frequently linked to major depressive disorder (MDD) and able to enhance symptoms severity and suicide risk. This study aimed to clarify whether patients with and without alexithymia may differ concerning illness presentation and clinical course, which is a major gap in the scientific literature. METHODS The present sample included 381 euthymic outpatients with MDD recruited at the Department of Neuroscience (DINOGMI), University of Genoa. The Toronto Alexithymia Scale (TAS-20) and additional rating scales (Clinical Global Impression (CGI), Hamilton Anxiety Rating Scale (HAM-A), Intent Score Scale (ISS) were administered to all participants. RESULTS Alexithymic patients were more likely to have lower educational level (11.6 ± 3.2 vs. 12.4 ± 3.4, p ≤ .05), have used previous psychiatric drugs (85.7% vs. 72.8%, p =.001), use current antidepressants (84.7% vs. 69.4%, p = <.001), and have higher cardiological comorbid disorders (10.7% vs. 5.0%, p = ≤.05). After multivariate analyses, alexithymia was associated with lower educational level (OR=0.928, p = .05), and higher current antidepressants use (OR 2.302, p = .01); difficulties in identifying feelings were associated with lower educational level (p = ≤.005), higher psychiatric comorbidity (p = ≤.001), and previous psychiatric medications (p = .01). Furthermore, having a lower educational level remained the only factor associated with both difficulties in communicating feelings (p = ≤.001) and thoughts oriented to external context (p = ≤.005). LIMITATIONS The study is limited by the small sample size and its cross-sectional nature. CONCLUSIONS Alexithymia appears a useful specifier of adverse outcomes, associated with distinct socio-demographic and clinical characteristics. Its identification would allow to provide a more personalized care.

Front Psychiatry 2020; 11:611489. [PMID: 33362614 PMCID: PMC7758403 DOI: 10.3389/fpsyt.2020.611489] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 11/12/2020] [Indexed: 02/06/2023] Open
Abstract
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.

Detecting Happiness Using Hyperspectral Imaging Technology. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2019; 2019:1965789.

Abstract
Hyperspectral imaging (HSI) technology can be used to detect human emotions based on the power of material discrimination from their faces. In this paper, HSI is used to remotely sense and distinguish blood chromophores in facial tissues and acquire an evaluation indicator (tissue oxygen saturation, StO2) using an optical absorption model. This study explored facial analysis while people were showing spontaneous expressions of happiness during social interaction. Happiness, as a psychological emotion, has been shown to be strongly linked to other activities such as physiological reaction and facial expression. Moreover, facial expression as a communicative motor behavior likely arises from musculoskeletal anatomy, neuromuscular activity, and individual personality. This paper quantified the neuromotor movements of tissues surrounding some regions of interest (ROIs) on smiling happily. Next, we selected six regions—the forehead, eye, nose, cheek, mouth, and chin—according to a facial action coding system (FACS). Nineteen segments were subsequently partitioned from the above ROIs. The affective data (StO2) of 23 young adults were acquired by HSI while the participants expressed emotions (calm or happy), and these were used to compare the significant differences in the variations of StO2 between the different ROIs through repeated measures analysis of variance. Results demonstrate that happiness causes different distributions in the variations of StO2 for the above ROIs; these are explained in depth in the article. This study establishes that facial tissue oxygen saturation is a valid and reliable physiological indicator of happiness and merits further research.

Abstract
INTRODUCTION It is not clear in the literature whether available instruments are sufficient to measure alexithymia because of its theoretical structure. Moreover, it has been reported that several measuring instruments are needed to measure this construct, and all the instruments have different error sources. The old and the new forms of Toronto Alexithymia Scale are the only instruments available in Turkish. Thus, the purpose of this study was to develop a new scale to measure alexithymia, selecting items and constructing the factor structure. METHODS A total of 1117 patients aged from 19 to 82 years (mean = 35.05 years) were included. A 100-item pool was prepared and applied to 628 women and 489 men. Data were analyzed using Explanatory Factor Analysis, Confirmatory Factor Analysis, and Item Response Theory and 28 items were selected. The new form of 28 items was applied to 415 university students, including 271 women and 144 men aged from 18 to 30 (mean=21.44). RESULTS The results of Explanatory Factor Analysis revealed a five-factor construct of "Solving and Expressing Affective Experiences," "External Locused Cognitive Style," "Tendency to Somatize Affections," "Imaginary Life and Visualization," and "Acting Impulsively," along with a two-factor construct representing the "Affective" and "Cognitive" components. All the components of the construct showed good model fit and high internal consistency. The new form was tested in terms of internal consistency, test-retest reliability, and concurrent validity using Toronto Alexithymia Scale as criteria and discriminative validity using Five-Factor Personality Inventory Short Form. CONCLUSION The results showed that the new scale met the basic psychometric requirements. Results have been discussed in line with related studies.

Abstract
Considering that impaired coping with stress is closely linked with emergence of stress-sensitive disorders most notably in alexithymic individuals, we conducted the first study examining stress-related autonomic reactivity in alexithymic pain disorder patients. Twenty-one pain disorder patients with high and an equivalent patient group with low alexithymia scores were exposed to three types of affect-inductive stimuli with variable affective involvement: arithmetic task, watching arousing video material and giving an oral presentation. Subjective appraisal of the induced emotional experience and physiological reactivity (heart rate, muscle tension and skin conductance) was documented. During oral presentation high alexithymia patients showed significantly lower skin conductance in combination with increased subjective negative affect compared to low alexithymia patients. Our results thus demonstrate a decoupling between physiological and affect processing in pain disorder patients with high alexithymia during a stressful situation that was subjectively associated with negative affect.

Abstract
Although a strong association between alexithymia and somatization has been postulated in numerous studies, no systematic study has investigated the psychometric properties of the 20-item Toronto Alexithymia Scale (TAS-20) in a sample of patients with somatoform disorder yet. The purpose of this study was to ensure a valid assessment by the German version of the TAS-20 in somatoform samples. We investigated whether the original three-factor model proposed by Bagby et al. (1994a), which is widely used in clinical research and practice, is replicable in a large sample of somatoform patients (n=806). Using confirmatory factor analysis (CFA) the goodness-of-fit of the originally proposed factor structure was compared to three factor models generated with exploratory factor analysis (EFA) and other factorial solutions derived from the literature. Our results demonstrate that the original three-factor model is not replicable in somatoform patients. Instead, the four-factor model by Franz et al. (2001b) described the data best. However, none of the models met all criteria of confirmatory factor analysis. Our results indicate that the three-factor model is not robust in the German version of the TAS-20. At this state of research we recommend to use the TAS-20 sum-score as a measure of alexithymia in somatoform patients in clinical practice.

Alexithymia is linked to neurocognitive, psychological, neuroendocrine, and immune dysfunction in persons living with HIV. Brain Behav Immun 2014; 36:165-75.

Abstract
The neuropathological changes resulting from Human Immunodeficiency Virus (HIV) infection may manifest in alexithymia (AL), a multidimensional trait characterized by impairments in the cognitive assimilation of feelings and emotions. A sample of 93 HIV survivors scoring high, i.e., ⩾74 on the 26-item Toronto Alexithymia Scale (TAS-26), were compared to 79 low AL (TAS-26⩽54) survivors on measures of neurocognitive, psychological, neuroendocrine and immune function. Neurocognitive function was evinced by a standardized test of psychomotor speed, cognitive flexibility and task switching ability, HIV Dementia and general cognitive status. Patients were also screened for levels of depression, anxiety and psychological stress. A 24-h urinary norepinephrine (NE) and cortisol (CORT) collection was taken; blood was drawn for T lymphocyte subset counts (CD4+CD3+) and HIV-1 viral load. Alexithymic patients exhibited higher levels of executive dysfunction, psychological distress, norepinephrine-to-cortisol (NE/CORT) ratio and viral load. Linear regression models accounting for sociodemographic and disease-related variables revealed two AL subscales, difficulties identifying and describing feelings, predicted and explained a significant proportion of variance in the outcome measures. Specifically, poorer executive task-switching/cognitive flexibility was associated with greater difficulty describing feelings; dysregulated autonomic response (high NE/CORT ratio) and depressive symptoms were predicted by difficulty identifying feelings; higher levels of anxiety and psychological stress were both predicted by greater difficulty describing and identifying feelings. Overall, the psychoneuroimmunological profile of alexithymia in HIV positive persons at mid-stage of infection suggests a greater vulnerability for disease progression.

Abstract
OBJECTIVE This randomized trial evaluated the therapeutic effect of emotional awareness training on the severity and frequency of pain in patients with irritable bowel syndrome (IBS). Patients' level of alexithymia was also measured. METHOD The study involved 100 patients diagnosed with IBS according to the Rome-III criteria. Patients' mean age was 34.98 years (standard deviation 10.22 years) and 60% of the patients were female. Seventy eligible patients were assigned randomly to one of two treatment groups. One group received standard symptom-oriented medical treatment only (MT group), while the second group, termed the emotional awareness group (EMT), was educated to increase conscious awareness of eight primary emotions in addition to receiving standard symptom-oriented medical treatment. This study was conducted over 20 months. All patients received 5 weeks of symptom-oriented medical treatment; patients in the EMT group also had two emotion awareness training sessions and recorded their emotions in a daily diary. Sixty patients completed the study. RESULTS Patients with IBS scored significantly higher on all aspects of alexithymia compared with healthy controls. The severity of pain decreased significantly in both groups, with a larger percentage of the patients in the EMT group who completed the study having a significant decrease in pain (54% in the EMT group vs. 36% in the MT group); this finding was replicated in an intent-to-treat analysis. The same results were observed for frequency of pain in patients who completed the study (59% in the EMT group vs 43.4% in the MT group), but this finding was not replicated in an intent-to-treat analysis. These patterns were not influenced by level of alexithymia, age, or gender. CONCLUSION Adding emotional awareness training to medical treatment resulted in a better therapeutic response in abdominal pain in patients with IBS.

Abstract
OBJECTIVE Many questionnaires for assessment of common somatic symptoms or functional somatic symptoms are available and their use differs greatly among studies. The prevalence and incidence of symptoms are partially determined by the methods used to assess them. As a result, comparison across studies is difficult. This article describes a systematic review of self-report questionnaires for somatic symptoms for use in large-scale studies and recommends two questionnaires for use in such studies. METHODS A literature search was performed in the databases Medline, PsycINFO and EMBASE. Articles that reported the development, evaluation, or review of a self-report somatic symptom measure were included. Instrument evaluation was based on validity and reliability, and their fitness for purpose in large scale studies, according to the PhenX criteria. RESULTS The literature search identified 40 questionnaires. The number of items within the questionnaires ranged from 5 to 78 items. In 70% of the questionnaires, headaches were included, followed by nausea/upset stomach (65%), shortness of breath/breathing trouble (58%), dizziness (55%), and (low) back pain/backaches (55%). Data on validity and reliability were reported and used for evaluation. CONCLUSION Questionnaires varied regarding usability and burden to participants, and relevance to a variety of populations and regions. Based on our criteria, the Patient Health Questionnaire-15 and the Symptom Checklist-90 somatization scale seem the most fit for purpose for use in large-scale studies. These two questionnaires have well-established psychometric properties, contain relevant symptoms, are relatively short, and are available in multiple languages.

Abstract
OBJECTIVES There is an ongoing debate concerning the temporal stability of alexithymia. Most previous studies have been conducted on clinical populations of psychiatric and somatic patients. However, psychiatric and somatic morbidity have been found to confound the findings so that in their presence, alexithymia appears to be less stable. Nevertheless, few general population studies have been published, and there have been no follow-ups longer than 5 years. METHOD In a population-based sample of middle-aged Finnish men, 755 participants completed the Toronto Alexithymia Scale (TAS)-26 at baseline and on 11-year follow-up. Absolute or mean stability refers to the extent to which scores change over time, and it was measured with group comparisons of paired samples. Relative stability refers to the consistency of relative differences in alexithymia levels among the study subjects, and it was measured with test-retest correlations. RESULTS Changes in the total scores and the subscales of the TAS-26 were all statistically significant but had low effect sizes (0.09-0.20) for the change-suggested absolute stability. The correlations between baseline and follow-up scores were high (ρ = 0.51-0.63), indicating relative stability. The exclusion of depressive symptoms, a history of mental illnesses, and cancer or cardiovascular diseases at baseline and at the 4- and 11-year follow-ups did not essentially alter these findings. Of the background variables, a higher age independently associated with the increase in the TAS-26 scores. Those with alexithymia at baseline were more likely to have elevated depressive symptoms at the 4- and 11-year follow-ups. CONCLUSIONS Both the absolute and relative stabilities of alexithymia in the general population are high, even for a long follow-up period. These results may support the assumption that alexithymia represents a stable personality trait in general. Alexithymia may increase vulnerability to depressive symptoms.

Abstract
OBJECTIVE To explore the associations between alexithymia and increased somatic morbidity. The mechanisms underlying these associations, however, are still unclear. Furthermore, data on the association between alexithymia and mortality are scarce. METHODS A total of 2321 Finnish men, aged 46 to 61 years, were followed up for an average of 20 years. Mortality rates were obtained from the national register. The associations between baseline alexithymia and cardiovascular disease (CVD), all-cause, injury, and cancer deaths were examined with adjustments for age and several behavioral (smoking, alcohol consumption, physical activity), physiological (low- and high-density lipoprotein cholesterol, body mass index, systolic blood pressure, history of CVD), and psychosocial (marital status, education, depression) factors. RESULTS After all adjustments, the risk of CVD death was increased by 1.2% for each 1-point increase in Toronto Alexithymia Scale-26 scores. CONCLUSIONS Alexithymia is associated with increased cardiovascular mortality.

Abstract
The maladaptive Type C coping style has been linked to disease progression in HIV and other immunologically mediated disorders. We hypothesized that strong Type C coping, higher levels of alexithymia, and greater cardiovascular (particularly heart rate) responses to, and prolonged recovery from stress would be associated with poorer functioning of immune parameters previously linked to HIV pathogenesis and progression: (1) antigen-stimulated production of the beta (beta)-chemokines MIP-1 alpha and MIP-1 beta, which bind to the HIV co-receptor CCR5 and block HIV entry into CD4(+) lymphocytes; and (2) antigen-stimulated production of the proinflammatory cytokine interleukin-6 (IL-6), which synergizes immune activation associated with HIV replication. We examined relations among psychological, cardiovascular, and immune variables in a baseline sample of 200 HIV-infected, predominantly African American outpatients attending an HIV primary care clinic in inner-city Baltimore. In regression analyses adjusted for CD4(+) count and age, strong Type C coping was associated with significantly higher IL-6 production, as predicted. The theoretically related construct of alexithymia was correlated with significantly lower stimulated production of HIV-inhibiting MIP-1 alpha. Independent of alexithymia, greater heart rate reactivity, and poorer heart rate recovery in response to experimental stressors were also significantly associated with lower production of MIP-1 alpha, adjusted for cardiovascular medications, methadone use, CD4(+) count, and age. These findings support our primary set of hypotheses that maladaptive Type C coping, alexithymia, and heart rate reactivity/recovery are associated with disturbances in two key immune parameters implicated in HIV pathogenesis. Our secondary hypothesis, that dysregulated heart rate reactivity may mediate the connections between Type C coping and/or alexithymia and IL-6/ MIP-1 alpha was not confirmed. The finding that Type C coping, alexithymia, and heart rate reactivity/recovery are associated independently and differentially with specific aspects of relevant immune functioning may reflect distinct biobehavioral pathways that contribute to HIV progression.

Abstract
The Toronto-Alexithymia-Scale (TAS-20) is used worldwide as a valid measurement of alexithymia. Until now, population-based standardization and cut-off values of the German TAS-20 version have not been available. This study provides these by means of a representative German sample and by investigating the factorial structure of the TAS-20. Data were generated from a representative random sample of the German general population (1,859 subjects aged between 20 and 69). The TAS-20 sum score was normally distributed. The mean value was 49.5 (SD=9.3) in men and 48.2 (SD=9.2) in women. Divorce, single and low social status were associated with enhanced sum scores. Ten percent of the population exceeded the TAS-20 sum score threshold of >or=61. The 66th percentile reached 53 for men and 52 for women. Factor analysis identified three factors that match the scales of the English original version. An additional fourth factor ("importance of emotional introspection") was extracted. Total explanation of variance by these four factors was 52.27%. The sum score of the German TAS-20 version is suited for the standardized measure of alexithymia. For selecting alexithymic individuals in experimental studies, the cut-off >or=61 is possibly too restrictive. Therefore, we propose the 66th percentile for the identification of high alexithymics. The TAS-20 sum score is associated with important socio-demographic variables. The factorial structure is reliable; the fourth factor ("importance of emotional introspection") provides differentiation of content and allows for enhanced explanation of variance.

Abstract
The effects of cooperative learning on selected psychological and social traits were investigated. The sample of the study included 114 freshmen and sophomores in a psychology of learning and a fundamental mathematics course, in a public university in Turkey. The University of California-Los
Angeles Loneliness Scale (R-UCLA; Russell, Peplau, & Cutrona, 1980), the Toronto Alexithymia Scale (TAS; Taylor, 1984), the Liebowitz Social Anxiety Scale (LSAS; Liebowitz, 1991), the Self-Monitoring Scale (SMS; Snyder, 1972), and the Happiness Scale (HS; Fordyce, 1988) were used to assess
the levels of loneliness, alexithymia, social anxiety, self-monitoring, and happiness. Results show that cooperative learning was effective in reducing the levels of loneliness and social anxiety and increasing the levels of happiness among the participants. However, it was found that cooperative
learning was not effective in increasing students' self-monitoring skills or decreasing their alexithymia levels.

Abstract
The authors assessed, in an adolescent population sample, the internal consistency, test-retest stability, and factor structure of the Toronto Alexithymia Scale (TAS-20) and established the frequency of alexithymia in this age-group. Pupils (N=882; age-groups: 14-, 15-, and 16-year-olds) from two secondary schools completed the TAS-20 questionnaire twice, with a 5-week interval, in a classroom survey setting. TAS total and subscale scores and proportion of subjects exceeding the cut-point for alexithymia are reported for boys and girls. In confirmatory factor analysis, all estimates except one item were statistically significant; there was no gender difference. The authors conclude that the TAS-20 has good psychometric properties in adolescent samples. Alexithymia rate decreases from early to middle adolescence and remains essentially on a level similar to that among adults.

Abstract
Alexithymia has been prospectively associated with all-cause mortality and with cardiovascular morbidity. Here, stress-induced autonomic reactivity and recovery were examined as potential pathways linking alexithymia to cardiovascular disease. The relation of alexithymia to blood pressure, heart rate, and other cardiovascular parameters derived from impedance cardiography (N = 80) and heart rate variability (N = 40) was evaluated during rest, an anger recall task and recovery in women (ages 18-30). During anger recall, alexithymia was associated with significantly attenuated heart rate and stroke index reactivity, greater low frequency power, and with marginally dampened blood pressure and high frequency power reactivity. Overall, this response pattern suggests blunted sympathetic activation and diminished vagal withdrawal. Alexithymia was also related to slower diastolic blood pressure and quicker preejection period recovery implying abbreviated sympathetic arousal and possibly greater vagal modulation. These results impart some evidence for the hypoarousal model of alexithymia during reactivity, but the hyperarousal model during recovery. Autonomic dysregulation during and following acute emotional stress is suggested as a possible physiological pathway connecting alexithymia to cardiovascular disease.

Abstract
OBJECTIVES The purpose of this research was to investigate alexithymia among parents of a daughter with eating disorders (EDs) and to relate alexithymia to personality and psychopathology characteristics. METHODS Parents of 73 women with ED (20 with anorexia nervosa, restrictive subtype (ANR), 23 with anorexia nervosa, bulimic subtype (ANB) and 30 with bulimia nervosa (BN)) and parents of 72 normal women were evaluated with the Toronto Alexithymia Scale (TAS-20), the Eysenck Personality Questionnaire, the Beck Depression Inventory and the Self-Rating Anxiety Scale. RESULTS The parents of daughters with ED show higher scores in the TAS-20 and its factors than the controls. TAS-20 scores of parents are associated with neuroticism, anxiety and depression. CONCLUSIONS Alexithymia in parents of daughters with an ED could be a trait of personality, but it could also be a state due to distress. Alexithymia should be taken into account in order to help these parents express emotions.

Abstract
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.

Abstract
OBJECTIVE To present a quantitative review of the empirical literature on somatisation and alexithymia. METHODS Medline and PsycLIT searches for relevant studies were conducted. Meta-analytical techniques were applied to quantify the strength of the associations that were found. RESULTS A small to moderate relationship was found between general alexithymia and somatic symptom reporting. The alexithymia dimension measuring difficulty in identifying feelings showed the strongest association with symptom reports. The alexithymia dimension measuring externally oriented thinking was virtually unrelated to somatic symptom reports. Compared to healthy control populations, subjects suffering from a somatoform condition were significantly more alexithymic, with effect sizes ranging from moderate to large. The studies comparing somatoform to medical or psychiatric conditions yielded inconclusive results. CONCLUSIONS By means of quantitative procedures, an association between general alexithymia and somatic symptom reporting was established. Due to the use of questionnaires that can only check for symptoms, not whether these symptoms are medically explained or not, it is however not possible to draw conclusions on somatisation properly defined. The inconsistent results found when comparing somatoform conditions to medical and psychiatric controls may be attributed to confounding variables. In future studies, these variables should be statistically controlled to establish a more consistent pattern of associations between somatoform conditions and alexithymia. It is, however, equally feasible that this inconsistency reflects the nonspecific character of the association between alexithymia and somatisation. The presence of only one prospective study does not allow to draw conclusions on alexithymia as a predisposing factor for somatisation.

Abstract
To examine the relationship between somatosensory amplification and three factors of alexithymia (difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking), 48 outpatients attending a Japanese psychosomatic clinic and 33 comparative outpatients completed the Somatosensory Amplification Scale (SSAS), 20-item Toronto Alexithymia Scale (TAS-20), Profile of Mood States (POMS), and other self-rating questionnaires. The scores on the SSAS and the first and second TAS-20 factors were higher (all P<0.001) in the psychosomatic group than in the comparison group. The SSAS was positively associated (both P<0.01) with these two TAS-20 factors, controlling for the effects of age, sex, group, and POMS tension-anxiety and depression. Somatosensory amplification appears to be associated with difficulties identifying and describing feelings, not externally oriented thinking, in Japanese patients.

Abstract
OBJECTIVE Laboratory studies of emotion-induced cardiovascular responses have been conducted predominantly with a specific affects approach rather than a dimensional approach. The purpose of this study was to apply the principles of the Circumplex Model of Affect (i.e., valence and arousal) to investigate cardiovascular reactivity during emotional activation in men and women. METHODS Forty-two healthy university students (mean age = 19.45, 52% women, 58% Caucasian) engaged in personally relevant recall tasks that varied as a function of valence and arousal. Self-reported valence and arousal, systolic and diastolic blood pressure (SBP and DBP, respectively), heart rate (HR), preejection period (PEP), stroke index (SI), cardiac index (CI), and total peripheral resistance (TPR) were measured during baseline and task periods. RESULTS Cardiovascular responses were found to be largely comparable across the recall tasks and were characterized by significant increases in blood pressure, HR, and TPR, and decreases in SI (Ps < .001). In addition, SBP during negative valence tasks was significantly higher than during positive valence tasks (P < .03), and PEP lengthened more during low as compared to high arousal tasks (P < .03). CONCLUSIONS These results highlight the similarity of hemodynamic adjustments during the verbal expression of emotion across gender and the dimensions of valence and arousal. The overall response pattern suggests alpha-adrenergically mediated sympathetic activation and vagal withdrawal.

Abstract
OBJECTIVE To review recent developments in alexithymia theory and research that are relevant to the field of psychosomatic medicine. METHOD Articles were selected from the alexithymia literature published over the past decade that describe advances in the theoretical understanding of alexithymia or report empirical investigations of the relationships of the construct with emotion regulation and with somatic illness and disease. Empirical investigations of the neural correlates of alexithymia were reviewed also, as were studies that explore therapeutic attempts to modify alexithymic characteristics. RESULTS The salient features of the alexithymia construct are now thought to reflect deficits in the cognitive processing and regulation of emotions. This is supported by studies showing that alexithymia is associated with maladaptive styles of emotion regulation, low emotional intelligence, a bidirectional interhemispheric transfer deficit, and reduced rapid eye movement (REM) density (number of eye movements divided by number of REM periods). Although empirical evidence demonstrates that alexithymia is associated with several somatic disorders, more prospective studies are required to establish the direction of causality. Preliminary data suggest that psychotherapies involving specific techniques to enhance emotional awareness and integrate symbolic and subsymbolic elements of emotion schemas may be effective in reducing alexithymic characteristics. CONCLUSION Alexithymia is proving to be a heuristically useful construct for exploring the role of personality and emotions in the pathogenesis of certain somatic illnesses and diseases.

Abstract
Some decennia ago, the concept of alexithymia was developed from the clinical experience of psychosomaticians who at the time were largely working within a psychoanalytic frame of reference. Alexithymia can briefly be described as a cognitive-affective disturbance characterized by difficulties in differentiating one's feelings and expressing them in words. Clinicians who treat patients with medically unexplained physical symptoms may often recognize alexithymic features in their patients. It is supposed that alexithymia could be a predisposing factor for the development or persistence of medically unexplained physical symptoms. In this review, the concept of alexithymia as well as paradigmatic shifts in psychoanalysis and psychosomatics are discussed to place the concept of alexithymia in its epistemiological context. Furthermore, the empirical literature on the association between alexithymia and medically unexplained physical symptoms is reviewed. The main conclusions are that alexithymia appears to be a theoretically important and clinically appealing concept, but that so far the empirical evidence that alexithymia predisposes to the development or persistence of medically unexplained physical symptoms is imperfect. This is mainly because of the cross-sectional design of most studies and is due to other methodological shortcomings, such as the lack of allowance for depression and anxiety as possible confounding factors. Suggestions for future research are made.

Abstract
Early clinical impressions that alexithymia is associated with diminished dream recall have been supported by more recent research. The present study was designed to examine this association using self-report measures and a carefully screened clinical population. Thirty-three male and 43 female asthmatics from an outpatient clinic were administered the Toronto Alexithymia Scale, the Eysenck Personality Questionnaire, and a questionnaire concerning retrospective recall of dreams and nightmares. Multiple regression analyses revealed that, among men, dream recall was negatively related to alexithymia, especially to the TAS analytical mode of thinking subscale, independent of age and neuroticism. Among women, dream and nightmare recall were positively correlated with neuroticism. These results are consistent with early clinical observations of pensée opératoire, with some research findings, and with the notion that dream recall may be differentially associated with components of alexithymia in men and women patients.

Abstract
We prospectively examined the association between alexithymia and risk of death over an average follow-up time of nearly 5.5 years in 42- to 60-year-old men (N = 2297) participating in the Kuopio Ischemic Heart Disease Risk Factor Study (KIHD). Alexithymia, impairment in identification, processing, and verbal expression of inner feelings, was assessed by the validated Toronto Alexithymia Scale (TAS) In age-adjusted survival analyses, men in the highest alexithymia quintile had a twofold greater risk of all-cause death (p < 0.001) and a threefold greater risk of death from accidents, injury, or violence (p < 0.02) relative to the men in the three lowest alexithymia quintiles. There was little evidence for confounding by behavioral factors (smoking, alcohol consumption, physical activity). physiological risk factors (LDL, HDL, body mass index, hypertension), socioeconomic status, marital status, perceived health, prior diseases and diagnoses, depressive symptoms or social connections. Consistent and even stronger associations between alexithymia and all-cause death were found in a healthy subgroup (N = 1650). Why difficulties in dealing with emotions associate with increased mortality remains unclear. Our findings suggest that the association is independent from the effect of well-known behavioral, biological, and psychosocial risk factors.

Abstract
The 20-item Toronto Alexithymia Scale (TAS-20) has been shown in previous research to measure a general dimension of alexithymia with three intercorrelated factors. This study evaluated the reliability and factorial validity of an Italian translation of the TAS-20 in a group of normal adults (N = 206) and in a mixed group of medical and psychiatric outpatients (N = 642). Using confirmatory factor analyses, the previously established three-factor model of the TAS-20 was found to be replicable in both groups. In addition, the Italian TAS-20 demonstrated adequate estimates of internal reliability and test-retest reliability. Although evaluation of the convergent, discriminant, and concurrent validity of the TAS-20 is required in Italian populations, the present results support the use of the Italian translation of the scale for clinical and research purposes.

Abstract
In discussions on the several methodological limitations in the assessment of alexithymia, uncertainty still remains about whether alexithymia and somatization are distinct constructs or whether they share overlapping symptomatology and constructs, as suggested by previous studies. In this study, 379 normal adults completed the newly developed 20-item Toronto Alexithymia Scale (TAS-20) and a screening list for DSM-III-R somatization disorder. Items from both the TAS-20 and the somatization checklist were subjected to factor analysis, resulting in separate factor loadings according to these two scales. These results were replicated and cross-validated in a sample of 125 psychosomatic inpatients, supporting the view of an independency between alexithymia and somatization.

Abstract
Research has demonstrated that alexithymic persons show a kind of defensive pseudonormality on psychological tests, minimizing problems and refusing to acknowledge psychological symptoms. The present study investigated whether alexithymic individuals are also unwilling to acknowledge the presence of a personality trait that is perceived by most adults as being undesirable (i.e., dependency). A mixed-sex sample of 372 psychiatric inpatients (209 women and 163 men) was screened for level of alexithymia; they completed self-report and projective measures of dependency. As predicted, there were significant negative correlations between alexithymia scores and scores on self-report measures of dependency in subjects of both sexes, but no significant relationships between subjects' alexithymia scores and their scores on the projective dependency measures. Apparently, alexithymic and nonalexithymic persons have comparable underlying dependency needs, but alexithymic persons are unwilling to acknowledge these needs on self-report tests.

Abstract
Recent studies have shown a partial similarity between posttraumatic stress disorder (PTSD) and alexithymia. In this study, the authors examined the relationship between PTSD and alexithymia in two samples of 26 patients with burn injury and 27 patients with digit amputation during rehabilitation. The prevalence rates of DSM-III-R PTSD and alexithymia assessed by the Toronto Alexithymia Scale (TAS) were significantly higher for injury patients than for healthy volunteers. The rate of PTSD symptoms of avoidance and emotional numbing was significantly and positively correlated with the TAS scores in injury patients. The PTSD symptoms of avoidance and emotional numbing had a significant relationship with function after digit replantation. Alexithymia also had a similar relationship with physical conditions. These results suggest that 1) in some cases, alexithymia may be evident when PTSD emotional symptoms appear in injury patients, and 2) emotional disturbances (i.e., PTSD symptoms of avoidance and emotional numbing and alexithymia) may be influenced by the level of functional recovery after digit replantation.

Abstract
The aim of the study was to determine the prevalence of alexithymia in an elderly Finnish population sample. Associations between alexithymia and sociodemographic factors were investigated, together with the relationship between alexithymia and perceived somatic health and self-reported psychic health. The study forms a part of the Turun Vanhustutkimus (TUR-VA) project, which is a longitudinal, prospective follow-up study dealing with psychosocial adaptation to retirement and to old age. The study group consisted of a population sample of 72-year-old people (N = 190). Alexithymia was measured with the 26-item version of the Toronto Alexithymia Scale (TAS-26). The prevalence of alexithymia was 34%. Alexithymia was associated with poor perceived somatic health. Alexithymia was associated with having a psychiatric disturbance (measured by the 36-item General Health Questionnaire [GHQ-36]), but this relationship disappeared when the influence of perceived somatic health was controlled for. Alexithymia was not associated with gender, marital status, social status, or residential area.

Abstract
The purported association between alexithymia and essential hypertension was investigated in a sample of 114 hypertensive patients using the well-validated twenty-item Toronto Alexithymia Scale. Alexithymia was also assessed in a group of 113 general psychiatric outpatients and in a group of 130 normal adults. A rate of 55.3% of alexithymia was found in the hypertensive group compared with significantly lower rates of 32.7% in the psychiatric group and 16.3% in the normal controls. The results support the view that a high prevalence of alexithymia may be found among patients with disorders that were categorized in the past as "classical" psychosomatic diseases. It is hypothesized that a deficit in the cognitive processing and modulation of emotions may leave alexithymic individuals prone to states of heightened sympathetic arousal that are conducive to the development of essential hypertension.

Abstract
Although many studies have been published about the relationship between alexithymia and different somatic diseases, little is known about the occurrence of alexithymia in primary health care patients. The aim of the present study was to shed light on this problem. The study forms part of a larger project dealing with psychiatric morbidity in primary health care patients. The original material consisted of 1,000 randomly selected adult patients in Turku in 1989-90. As part of a follow-up study (N = 748) three years later, alexithymia was measured using the Toronto Alexithymia Scale (TAS). Primary care patients seemed to have commonly alexithymic features: The mean of the TAS-score was 64.41 +/- 11.71 for male and 63.51 +/- 11.86 for female patients. The results indicated that alexithymia was associated with psychological distress, age, educational level, and socioeconomic status. The nature of alexithymia is discussed.

Abstract
The aim of the study was to examine the factor structure of alexithymia in patients with eating disorders and to compare scores on these factors with a non-eating disordered population. The Toronto Alexithymia Scale (TAS) was given to patients with restricting anorexia nervosa (AN/R, n = 29), bulimia nervosa (BN, n = 83), anorexia with a subtype bulimia (AN/BN, n = 15), and 79 female students. Factors were extracted using a principal-components factor analysis. Four factors were found--inability to Identify Feelings, Paucity of Fantasy, Noncommunication of Feelings, and Concrete Thinking. All three eating disorder groups were less able to identify their feelings than the comparison group and AN/R patients had a more diminished fantasy life than BN patients and students. Groups did not differ significantly on concrete thinking but there was a trend towards significance on noncommunication of feelings, with patient groups expressing their feelings less than comparison subjects. Differences between patient groups on factors of the TAS suggest that scores are not simply a result of psychopathology in general. Approaches which promote the identification and expression of feelings may be particularly useful in the treatment of eating disorders.

Abstract
We examined the relationship between alexithymia and coping with stress among 179 Japanese healthy volunteers. Two correlational analyses indicated that persons scored as alexithymic were more likely to indicate lower social support and poorer responses to stress. Multiple regression analysis also indicated that these lowered coping responses were fully explained by alexithymia scores. These results suggest that alexithymia, as a personality trait, may help to explain these individuals' low social support and poor responses to stress.

Abstract
Disturbances in emotional awareness, sometimes referred to as alexithymia, have been hypothesized to contribute to the development of binge/purge symptoms among women with bulimia nervosa (BN) and/or are considered secondary to the state of depression and/or disordered eating. The present study was designed to assess alexithymia among women with BN, to evaluate the interrelationship between alexithymia, depression, and somatic symptoms, and to determine whether an intensive group psychotherapy program contributes to a reduction in the degree of alexithymia. Thirty-one of 50 BN women (62%) who completed The Toronto Hospital Day Hospital Program for Eating Disorders (DHP) were administered pretreatment and posttreatment questionnaires. Findings from this clinical sample were compared with those from 20 non-eating-disordered women who completed the same battery. Using the Toronto Alexithymia Scale (TAS), significantly more BN women were alexithymic at pretreatment (61.3%) and post-treatment (32.3%) than in the comparison group (5.0%), even when depression was controlled for. At discharge, abstinence from binge/purge episodes was associated with a significant reduction in alexithymia, although there was a significant correlation between TAS scores, depression, and vomit frequency. Alexithymia among BN women is not simply a concomitant of disordered eating. Its partial reversibility following an intensive psychotherapy program may be a direct effect of the treatment and/or may be secondary to a reduction in depressive and/or binge/purge symptoms.

Abstract
In previous studies, results from psychometric measures suggested an association between alexithymia and somatization. However, alexithymia has not been examined in relation to somatoform disorders and other standard psychiatric diagnoses. In the present study, the prevalence of DSM-III-R diagnoses was determined by SCID interviews among 45 psychiatric inpatients with functional somatic syndromes. In addition, the Toronto Alexithymia Scale (TAS) and the SCL-90-R were administered. Of the sample, 42.2% scored in the alexithymic range of the TAS. The alexithymic patients presented significantly more psychological turmoil and overall psychopathology on the SCL-90-R, as well as a significantly higher number of current DSM-III-R diagnoses. However, alexithymia was unrelated to DSM-III-R somatoform disorders and other DSM-III-R diagnoses, as well as the course of illness. These results suggest that assessing clinical features in addition to psychometric measures seems to be necessary for further validating the potential role of the alexithymia construct in somatic symptom formation.

Abstract
This study examined the relationship between characteristics of alexithymia and eating disorders (anorexia nervosa, bulimia nervosa, and obesity) in a nonclinical sample of 308 college women. Scores on the Toronto Alexithymia Scale were mostly unrelated to a weight index, which assessed subjects' deviation from their expected weight, but were correlated with subjects' scores on the Eating Disorders Inventory (EDI). EDI scores were related to the affective deficits of alexithymia (difficulty identifying and communicating feelings), but not to the cognitive disturbance associated with alexithymia.
