Abstract
Chronic pain, with its complex and multidimensional nature, poses significant challenges in identifying effective long-term treatments. There is growing scientific interest in how psychopathological and personality dimensions may influence the maintenance and development of chronic pain. This longitudinal study aimed to investigate whether alexithymia can predict the improvement of pain severity following a treatment-as-usual programme for chronic musculoskeletal pain over and above psychological cofactors (emotional distress, catastrophizing, and self-efficacy). A consecutive sample of 129 patients with diagnosed chronic musculoskeletal pain referred to two tertiary care centres was recruited and treated for 16 weeks. Clinical pain, psychological distress, self-efficacy, catastrophizing, and alexithymia were assessed with validated self-report measures at the first medical visit (T0) and at 16-week follow-up (T1). Compared with non-responder patients (n = 72, 55.8%), those who responded (i.e., reduction of >30% in pain severity; n = 57, 44.2%) reported an overall improvement in psychological variables except alexithymia. Alexithymia showed relative stability between baseline and follow-up within the entire sample and remained a significant predictor of treatment outcome even when other predictive cofactors (i.e., pain interference, depressive symptoms, and catastrophizing) were considered simultaneously. Our results suggest that identifying patients with a co-occurrence between alexithymia, depressive symptoms, catastrophizing, and the stressful experience of chronic pain can be clinically relevant in pain prevention and intervention programs.

Abstract
BACKGROUND Type 1 Diabetes Mellitus (T1DM) represents a serious chronic condition affecting a wide number of people. Discussion of the physical issues associated with T1DM pervades the literature, however, there is less discussion of the psychological consequences. Mental health difficulties, alexithymia and uncertainty are present in this population, and known to be harmful for the onset, maintenance and worsening of T1DM. This study aimed to evaluate the presence of these phenomena in people with T1DM. METHODS 105 participants aged between 11 and 17 years old (M: 13.88; SD: 2.16) affected by T1DM were included in the sample. To assess the presence of mental health difficulties, SAFA scales (Depression, Anxiety and Somatic symptoms) were included in the protocol together with TAS-20 and IUS-12, which evaluate the presence and role of alexithymia and intolerance to uncertainty in the sample, respectively. RESULTS A concerning presence of anxiety, depression and somatic symptoms was found in the sample. Mental health difficulties appeared to be consistently present in the sample, often overcoming pathological thesholds. Alexithymia and uncertainty were also common, highlighting their role in T1DM. CONCLUSIONS Active mental health difficulties together with high rates of alexithymia and intolerance to uncertainty were prevalent in the sample of adolescents with diabetes.

Quality of Life and Its Psychosocial Predictors among Patients with Disorders of Gut-Brain Interaction: A Comparison with Age- and Sex-Matched Controls. Healthcare (Basel) 2024; 12:757. [PMID: 38610179 PMCID: PMC11011672 DOI: 10.3390/healthcare12070757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 02/07/2024] [Accepted: 03/28/2024] [Indexed: 04/14/2024] Open
Abstract
The disorders of gut-brain interaction (DGBIs) are a heterogeneous group of chronic conditions that greatly reduce patients' quality of life (QoL). To date, biopsychosocial factors (such as gastrointestinal symptoms, alexithymia, and interpersonal problems) are believed to contribute to the development and maintenance of DGBIs, but their role in affecting patients' QoL is still under investigation. Out of 141 patients seeking treatment for their gastrointestinal symptoms, 71 were diagnosed with a DGBI (47 females, 66.2%; Mage: 41.49 ± 17.23 years) and were age- and sex-matched to 71 healthy controls (47 females, 66.2%; Mage: 40.45 ± 16.38 years) without any current gastrointestinal symptom or diagnosis. Participants completed a sociodemographic and clinical questionnaire and a survey investigating several psychosocial risk factors. We found greater symptom severity and difficulties in identifying feelings among patients compared to controls. Further, multiple linear regression analyses evidenced that, among patients, higher expressive suppression of emotions, difficulties in identifying feelings and interpersonal problems, and a lower cognitive reappraisal of emotions predicted lower QoL. Data suggest that the QoL of patients with DGBIs is affected not only by common risk factors (e.g., interpersonal problems) but also by specific difficulties in processing and regulating emotions. The implications of these findings are discussed.

J Pers Assess 2024; 106:242-253. [PMID: 37144843 DOI: 10.1080/00223891.2023.2201831] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 03/28/2023] [Indexed: 05/06/2023]
Abstract
The 20-item Toronto Alexithymia Scale (TAS-20) is the most widely used instrument for assessing alexithymia, with more than 25 years of research supporting its reliability and validity. The items that compose this scale were written to operationalize the components of the construct that are based on clinical observations of patients and thought to reflect deficits in the cognitive processing of emotions. The Perth Alexithymia Questionnaire (PAQ) is a recently introduced measure and is based on a theoretical attention-appraisal model of alexithymia. An important step with any newly developed measure is to evaluate whether it demonstrates incremental validity over existing measures. In this study using a community sample (N = 759), a series of hierarchical regression analyses were conducted that included an array of measures assessing constructs closely associated with alexithymia. Overall, the TAS-20 showed strong associations with these various constructs to which the PAQ was unable to add any meaningful increase in prediction relative to the TAS-20. We conclude that until future studies with clinical samples using several different criterion variables demonstrate incremental validity of the PAQ, the TAS-20 should remain the self-report measure of choice for clinicians and researchers assessing alexithymia, albeit as part of a multi-method approach.

Abstract
Chronic tinnitus, the perception of sound without an external source, can significantly affect individuals' well-being. As an often medically unexplained symptom, chronic tinnitus can present as a "somatoform" or "functional" difficulty. Some evidence has pointed to alexithymia as a transdiagnostically relevant risk factor for both symptom clusters. Using a two-part rapid review-searching within EBSCO, Embase by Ovid, PubMed, Web of Science-we summarize psychological studies regarding alexithymia, i.e., difficulties in recognizing and expressing emotions and (1) somatoform conditions and (2) chronic tinnitus. For the former (inclusion criteria: (1) adult human beings with different kinds of somatization, (2) longitudinal study designs, (3) publication between 2001 and 2021, (4) full-text in English or German) we identified eight studies that revealed significant links between alexithymia and somatoform conditions. Psychotherapy improved alexithymia in most studies. Additionally, alexithymia was associated with broader treatment outcomes such as improvements in pain intensity, gastrointestinal symptoms, and patient-therapist alliance. The 'Risk Of Bias In Non-randomized Studies-of Interventions' tool (ROBINS-I) and 'Revised Cochrane risk-of-bias tool for randomized trials' (RoB 2) were used for risk of bias assessment. Summarizing all available studies on alexithymia and chronic tinnitus, we identified three studies. Inclusion criteria were: (1) adult human beings with chronic tinnitus, (2) publication between 2001 and 2021, (3) full-text in English or German. Risk of bias was assessed by the 'JBI Critical Appraisal Checklist for Analytical Cross Sectional Studies'. The available studies suggested a high rate of alexithymia (65.7%) in patients with chronic tinnitus. Tinnitus-related distress was significantly associated with alexithymia in two studies, one of which, however, found no differences in alexithymia between patients with bothersome versus non-bothersome tinnitus. Conversely, one study reported high levels of alexithymia in patients with low levels of tinnitus-related distress. Overall, alexithymia may be a transdiagnostic psychological indicator of somatization phenomena, which might include some chronic tinnitus presentations. Psychotherapy likely improves alexithymia as well as somatoform symptom presentations.

Abstract
Background Research has shown that many autistic people have alexithymia, a psychological trait characterized by difficulties in identifying and describing emotions. It is also now clear that there is a high rate of autism among transgender people, but we know little about the intersection of autism and gender diversity or about the clinical features of autistic transgender individuals. Methods Seventy-eight nonautistic transgender, 56 autistic transgender, 106 nonautistic cisgender, and 107 autistic cisgender adults completed the Toronto Alexithymia Scale-20 and the Autism-spectrum Quotient as part of an online study. We also used the General Alexithymia Factor Score-8 as an additional alexithymia score. Results We found that nonautistic transgender participants reported significantly higher mean levels of alexithymia than nonautistic cisgender participants, and that there was a significant overrepresentation of individuals in this group who met the clinical cutoff for alexithymia. The difference in alexithymia between autistic cisgender and autistic transgender participants was nonsignificant, with >50% of each group scoring above the clinical cutoff point. Of note, when we used the General Alexithymia Factor Score-8, the difference between autistic transgender participants and autistic cisgender participants was significant, with autistic transgender participants reporting higher mean levels of alexithymia. Conclusion Results suggest that nonautistic transgender individuals might be more prone to experience alexithymia (including at clinically significant levels) than nonautistic cisgender people. When autism occurs in transgender people, the average level and clinical rate of alexithymia is higher than among nonautistic transgender people and potentially higher than among autistic cisgender people. Our findings are in keeping with evidence of a subgroup of transgender people with "subclinical autism" and inconsistent with the notion that autism among transgender and gender diverse people is a "phenomimic" of autism. Lastly, our study highlights the potential importance of screening autistic and nonautistic transgender people for alexithymia.

Abstract
OBJECTIVE To explore possible associations between alexithymia and health literacy (HL) in persons with psoriasis. METHODS We conducted a cross-sectional study, including 825 persons with moderate to severe psoriasis, using the Toronto Alexithymia Scale, and the Health Literacy Questionnaire. Descriptive statistics compare HL means between alexithymic and not alexithymic participants. Associations between alexithymia and HL are analyzed using a linear multiple regression model. RESULTS Twenty-six percent of the participants were characterized as alexithymic, and 26.8% had borderline alexithymia. Higher alexithymia scores were associated with lower education, biological medicines, and more comorbidities, together with lower self-efficacy. The HL domains with the strongest associations with alexithymia were those focusing on managing and getting support for health, as well as the ability to find health information. CONCLUSION A more elevated alexithymia score is associated with lower HL. Further studies of these associations may contribute to a more comprehensive perspective of psoriasis. To know a patient's alexithymia level and HL needs may guide health care personnel's understanding of possible associations between health status, clinical presentation, behavior, and response to treatment.

Abstract
Background: Previous studies have shown that many personality traits are associated with fibromyalgia (FM), worsening both the quality of life and psychological distress of patients. Despite the high comorbidity of psychopathological disorders in this syndrome and their association with immature defense styles, few studies have examined the defense mechanisms used by FM patients. The main aim of our study was to investigate personality traits and defense mechanisms in FM patients compared to in a healthy control group (HC). Moreover, we investigated the effect of personality traits and defense mechanisms on psychological distress in both FM and HC groups. Methods: A total of 54 women with FM and 54 healthy women completed the (1) Temperament and Character Inventory—Revised; (2) the Toronto Alexithymia Scale; (3) the Defense Style Questionnaire; and (4) the Hospital Anxiety and Depression Scale. Results: The results indicated that FM patients display higher alexithymia, higher harm avoidance, lower self-directedness, lower persistence, and the higher use of a maladaptive defense style compared to HC. We found that alexithymia, harm avoidance, and maladaptive defense style are significant predictors of patients’ psychological distress. Moreover, harm avoidance and adaptive defense style significantly predicted psychological distress in the HC group. Conclusion: The present study is the first to explore the contribution of both defense mechanisms and personality characteristics on the psychological distress of FM patients. Our findings have important clinical implications and may help diagnose and treat FM patients more in depth.

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

Abstract
BACKGROUND: Emotional processing scale (EPS) is a fundamental test for measurement of the abnormal processing of emotion and psychosomatic disorders in psychotherapy sessions. Despite its importance, EPS has not been yet translated and validated in the Iranian population.
AIM: To fill this gap, this study aims to adapt and examined the psychometric properties of five EPS in the Iranian population. Using cluster sampling, we selected 1283 university students.
METHODS: The structural equation modeling and confirmatory factor analysis used to analyze the assessment of validity.
RESULTS: The result showed the Cronbach’s alpha, split half, and test re-test reliability in acceptable ranges; 0.91, 0.90, and 0.91, respectively, for total scores scale. Root Mean Square Error of Approximation, Standardized Root Mean Square Residual, goodness of fit, and comparative fit index were at an acceptable range, 0.07, 0.05, 0.90, 0.90, 0.89, and 0.85, respectively. The total scores of EPS also showed a positive correlation (0.63, p < 0.001) with GHQ 28.
CONCLUSION: The result suggested that five factors model of EPS which includes: The suppression, sign of unprocessed emotion, unregulated emotion, avoidance, and impoverished emotional experience model fit the data well be most appropriated for Iranian population.

Abstract
Objective: Deficits in affective processing are associated with impairments in both mental and physical health. The role of affective processing in patients with functional somatic complaints such as irritable bowel syndrome (IBS) remains unclear. Most studies have focused on the capacity for emotional awareness and expression, but neglect other dimensions of affective processing. Therefore, this study aimed to systematically analyze differences in six different dimensions of affective processing between patients with IBS and healthy controls (HCs). Additionally, we exploratively investigated the impact of IBS symptom severity, psychological distress, and attachment styles on affective processing in IBS. Methods: A controlled cross-sectional multi-center study was conducted. Overall, 127 patients with IBS were compared with 127 matched HCs using multivariate analysis of variances. Affective processing was operationalized in line with the affect cascade model on six specific dimensions: emotional experience, emotional awareness, affect tolerance, affect differentiation, affect regulation, and emotional communication. They were measured using two subscales of the Mentalizing Questionnaire (MZQ) and four subscales of the Operationalized Psychodynamic Diagnosis-Structure Questionnaire (OPD-SQ). Linear regression analysis was used to investigate the influence of IBS symptom severity (IBS-Severity Scoring System, IBS-SSS), depression (Patient Health Questionnaire, PHQ-9), anxiety (General Anxiety Disorder, GAD-7), and anxious and avoidant attachment styles (Experiences in Close Relationships Scale, ECR-RD12) on the different dimensions of affective processing in IBS. Results: Patients with IBS compared to HCs showed deficits in all six dimensions of affective processing. Deficits were largest for affect tolerance (d = 0.849) and lowest for emotional experience (d = 0.222) and emotional awareness (d = 0.420). Moderate effect sizes were found for affect differentiation (d = 0.773), emotional communication (d = 0.665), and affect regulation (d = 0.552). Moreover, explorative analyses indicated that affective processing in patients with IBS was significantly influenced by levels of anxiety and insecure attachment. Conclusion: The results indicate a specific pattern of affective processing abilities in patients with IBS. The deficits in affective processing are more prominent in the area of understanding and tolerating difficult affective states than experiencing affective states. This opens interesting perspectives for the development of specific psychotherapeutic interventions. Clinical Trial Registration: DRKS00011685.

Williams ZJ, Gotham KO. Improving the measurement of alexithymia in autistic adults: a psychometric investigation and refinement of the twenty-item Toronto Alexithymia Scale. Mol Autism 2021; 12:20. [PMID: 33653400 PMCID: PMC7971146 DOI: 10.1186/s13229-021-00427-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 02/19/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Alexithymia, a personality trait characterized by difficulties interpreting one's own emotional states, is commonly elevated in autistic adults, and a growing body of literature suggests that this trait underlies a number of cognitive and emotional differences previously attributed to autism, such as difficulties in facial emotion recognition and reduced empathy. Although questionnaires such as the twenty-item Toronto Alexithymia Scale (TAS-20) are frequently used to measure alexithymia in the autistic population, few studies have attempted to determine the psychometric properties of these questionnaires in autistic adults, including whether differential item functioning (I-DIF) exists between autistic and general population adults. METHODS We conducted an in-depth psychometric analysis of the TAS-20 in a large sample of 743 verbal autistic adults recruited from the Simons Foundation SPARK participant pool and 721 general population controls enrolled in a large international psychological study (the Human Penguin Project). The factor structure of the TAS-20 was examined using confirmatory factor analysis, and item response theory was used to further refine the scale based on local model misfit and I-DIF between the groups. Correlations between alexithymia and other clinical outcomes such as autistic traits, anxiety, and quality-of-life were used to assess the nomological validity of the revised alexithymia scale in the SPARK sample. RESULTS The TAS-20 did not exhibit adequate global model fit in either the autistic or general population samples. Empirically driven item reduction was undertaken, resulting in an eight-item unidimensional scale (TAS-8) with sound psychometric properties and practically ignorable I-DIF between diagnostic groups. Correlational analyses indicated that TAS-8 scores meaningfully predict autistic trait levels, anxiety and depression symptoms, and quality of life, even after controlling for trait neuroticism. LIMITATIONS Limitations of the current study include a sample of autistic adults that was overwhelmingly female, later-diagnosed, and well-educated; clinical and control groups drawn from different studies with variable measures; and an inability to test several other important psychometric characteristics of the TAS-8, including sensitivity to change and I-DIF across multiple administrations. CONCLUSIONS These results indicate the potential of the TAS-8 as a psychometrically robust tool to measure alexithymia in both autistic and non-autistic adults. A free online score calculator has been created to facilitate the use of norm-referenced TAS-8 latent trait scores in research applications (available at http://asdmeasures.shinyapps.io/TAS8_Score ).

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

Abstract
This research studies the relationship between Alexithymia, behavioural, biometric, biochemical and cardiovascular risk in clinical and healthy samples. There were 602 participants (mean age of 52.82 ± 10.59) divided into two groups. The first was made up of 202 patients (165 males and 37 females) who had suffered a cardiovascular disease (CVD), while the second was composed of 400 (285 males and 115 females) healthy volunteers without CVD diagnosis. A cardiovascular risk index (CRI) was developed with the high factorial loading of the following variables: systolic and diastolic blood pressure, total cholesterol/HDL, triglycerides, body mass index, glucose and alcohol and tobacco consumption. The results showed a significant correlation between Alexithymia and the CRI. After controlling for age, sex, occupation, alcohol and tobacco consumption, this correlation decreased, but remained significant for most values. Alexithymia predicted 6% of CRI in the entire sample, once age and sex effect were discounted. Alexithymic subjects with scores above a cut-off point set at higher than 60 had higher levels of glucose, systolic, diastolic, cholesterol/HDL and cardiovascular risk. We discuss that Alexithymia scores contribute to cardiovascular risk, supporting previous findings.

Abstract
OBJECTIVE The clinical management of high symptom severity is a challenging task with patients with functional somatic disorders. We investigated the extent to which DCPR-revised (DCPR-R) syndromes and the DSM-5 category of Somatic Symptom Disorder (SSD) were able to predict symptom severity in 203 consecutive tertiary care patients with irritable bowel syndrome (IBS). METHOD Semistructured interview were used for assessing DCPR-R and validated scales for SSD (combining PHQ-12 and WI-7), severity of symptoms (IBS-SSS), psychological distress (HADS), and psychosocial functioning (SF-12). RESULTS Compared to moderate severity (IBS-SSS = 175-300), patients in the high range of severity (IBS-SSS > 300) had significantly more DCPR-R syndromes (particularly alexithymia and persistent somatization), higher psychological distress, and poorer psychosocial functioning, but showed no difference for SSD. DCPR-R, particularly alexithymia and persistent somatization, significantly and independently predicted IBS severity by explaining 18.5% of the IBS-SSS variance with large effect size (d = 1.18), after controlling for covariables. Conversely, SSD was not able to significantly predict IBS severity. CONCLUSIONS This study highlights the need of an integrative approach in the medical setting. Psychosomatic factors play a relevant role in the individual perception of symptom severity and should be carefully evaluated for clinical management of functional syndromes.

Abstract
OBJECTIVE Twenty-five years ago, this journal published two articles reporting the development and initial validation of the 20-Item Toronto Alexithymia Scale (TAS-20). Since then the literature on alexithymia has burgeoned with the vast majority of this research using the TAS-20, including multiple language translations of the scale. METHOD In this article we review the psychometric literature evaluating various aspects of the reliability and validity of the TAS-20 and examine some of the controversies surrounding the scale and the construct it assesses. We reflect on the ways in which the TAS-20 has advanced the measurement of the construct and theory of alexithymia. We also discuss recent developments and some future directions for the measurement of alexithymia. RESULTS Although not without some controversy, the preponderance of the accumulated evidence over a 25-year period supports various aspects of the reliability and validity of the TAS-20, including findings from confirmatory factor analytic and convergent and discriminant validity studies which are consistent with Nemiah et al.'s (Nemiah et al., 1976 [3]) and Taylor and colleagues (Taylor et al., 1997 [9]) theoretical formulations and definition of the alexithymia construct. CONCLUSIONS Based on the accumulated empirical evidence of 25 years, we conclude that the TAS-20 is a reliable and valid instrument and accurately reflects and measures the construct as it was originally defined by Nemiah et al. Nemiah et al. (1976) [3] as composed of deficits in affect awareness and expression and pensée opératoire (operational thinking). Clinicians and researchers can use the TAS-20 to confidently measure alexithymia, the roots of which have foundations in psychosomatic medicine.

Abstract
UNLABELLED Treatment of psychiatric disorders relies heavily on a trial and error approach, often prolonging the time required to obtain symptomatic improvements. The identification of reliable predictors of treatment response is instrumental to enact an individualized approach. Alexithymia represents a personality trait reflecting an intrinsic difficulty in recognizing the emotional components of subjective experiences. Thus, its modulating role on treatment outcome has gathered substantial attention during the past years. In the present paper, we aimed at exploring the available evidence for Alexithymia role in influencing the treatment outcome on a wide range of psychiatric conditions by means of a systematic review. DATA SOURCE We performed a systematic review in Medline and Scopus, augmented by tracking the reference list of the pertinent articles. INCLUSION CRITERIA To be included in this review, research studies had to assess alexithymia impact on a treatment intervention delivered to manage a primary psychiatric disorder. STUDY EVALUATION AND DATA SYNTHESIS After removing duplicates, titles were screened first, then abstracts, and last full texts were read, eventually leading to the inclusion or exclusion of the papers according to the criteria established before the online search. Then results of the search were downloaded in.xml format and uploaded in Rayyan, a free web software, that helps expedite the initial screening of abstracts and titles using a process of semi-automation while incorporating a high level of usability. After uploading, screening of the literature was performed in blind by two investigators. Disagreement between reviewers was resolved by joint discussion with a third senior investigator. The quality of evidence was assessed using the Newcastle Ottawa Scale. Thereafter, the data considered relevant was extracted and synthetized in this paper. RESULTS Our search yielded a total of 30 articles dealing with a wide range of psychiatric conditions and exploring both pharmacological and psychotherapeutic interventions. Several lines of evidence suggest a complex role for alexithymia in influencing the psychiatric treatment outcome, further underscoring the need for additional research in this area to better address the existing knowledge gaps.

Abstract
Alexithymia is of great interest as an outcome predictor of recovery from anorexia nervosa, since it may interfere with both treatment compliance and patients' ability to benefit from the adopted interventions. For this reason, in the last years new treatment approaches targeting emotion identification, expression, and regulation have been applied and tested. Using the PRISMA methodology, we performed a scoping review of the literature about treatment outcome in anorexia nervosa, in terms of changes in alexithymia as assessed by its most commonly used self-report measure, the Toronto Alexithymia Scale (TAS). The Medline and Scopus databases were searched, and articles were included if matching the following criteria: dealing with patients affected by anorexia nervosa, without limits of age; involving the application of any kind of targeted therapy or treatment; assessing alexithymia and the effect of a treatment intervention on alexithymia, using the TAS. Ten studies were eventually included; overall, according to the selected studies, alexithymia levels often remain high even after specific treatment. Further research aimed at a deeper understanding of the actual impact of alexithymia on the outcome of anorexia, as well as exploring alternative treatment strategies for alexithymia in eating disorders (EDs), are warranted.

Abstract
Obesity is a psychosomatic condition characterized by a complex interaction of biological and psychological factors and a large body of research has aimed to identify variables limiting efficacy and determining high attrition rates in weight loss programs. In this study, we used the Diagnostic Criteria for Psychosomatic Research (DCPR), designed to broaden the clinician's perspective on patients' problems by providing additional clinical information not found in the more traditional psychiatric classification, to predict psychosomatic variables that may limit efficacy and determine attrition in clinical interventions with people with obesity. We evaluated 82 consecutive participants with obesity at baseline for psychopathology, psychosomatic correlates, psychological distress, and eating-related symptoms before entering a weight loss program. Regression models were used to assess attrition and outcome at a 6-month follow-up and per-protocol and intention-to-treat analyses were performed. DPCR alexithymia significantly predicted attrition (OR = 6.9), and unsuccessful weight-loss (OR = 11.3). These findings suggest that the identification of psychosomatic factors, in addition to psychological and psychopathological factors, may predict adherence to weight-loss programs.

Abstract
BACKGROUND Associations of alexithymia with temporomandibular pain disorders (TMD), facial pain, head pain and migraine have been described, but the role of the different dimensions of alexithymia in pain development remained incompletely understood. OBJECTIVES We sought to investigate the associations of alexithymia and its subfactors with signs of TMD and with facial pain, head pain and migraine in the general population. METHODS A total of 1494 subjects from the general population completed the Toronto Alexithymia Scale-20 (TAS-20) and underwent a clinical functional examination with palpation of the temporomandibular joint and masticatory muscles. Facial pain, migraine and head pain were defined by questionnaire. A set of logistic regression analyses was applied with adjustment for age, sex, education, number of traumatic events, depressive symptoms and anxiety. RESULTS Alexithymia was associated with TMD joint pain (Odds Ratio 2.63; 95% confidence interval 1.60-4.32 for 61 TAS-20 points vs the median of the TAS-20 score) and with facial pain severity (Odds Ratio 3.22; 95% confidence interval 1.79-5.79). Differential effects of the subfactors were discovered with difficulties in identifying feelings as main predictor for joint, facial, and head pain, and externally oriented thinking (EOT) as U-shaped and strongest predictor for migraine. CONCLUSION Alexithymia was moderately to strongly associated with signs and symptoms of TMD. These results should encourage dental practioners using the TAS-20 in clinical practice, to screen TMD, facial or head pain patients for alexithymia and could also help treating alexithymic TMD, facial or head pain patients.

Abstract
BACKGROUND Negativity is often observed in patients with irritable bowel syndrome (IBS). No study has examined their emotional expressiveness as a marker of emotional reactivity. We investigated IBS patients' vulnerability to an emotional load by associating their expressiveness with psychological and neurophysiological assessments. We hypothesized that IBS would be characterized by a lack of expressiveness coupled with high scores in psychological and neurophysiological parameters. METHODS We assessed the emotional facial expressions (EMFACS), psychological (anxiety, depression, alexithymia), and neurophysiological (cortisol, heart rate variability (HRV)) parameters of 25 IBS patients and 26 healthy controls (HC) while they watched fear-eliciting movie extracts. KEY RESULTS Overall, the task elicited an increase in state anxiety and consistent HRV responses. However, IBS patients differed from HC as they displayed more sadness and tended to display more rage. Contrary to HC, IBS patients showed an increase in heart rate and a decrease in parasympathetic regulation, reflecting an enhanced responsiveness corroborated by higher scores in depression and state anxiety. Consistent with their higher difficulty in identifying feelings, a component of alexithymia positively correlated with their expressions of rage, they were not aware of their increase in anxiety during the task, whereas HC were. No linear relationship between patients' expressions and their neurophysiological responses was found. CONCLUSIONS & INFERENCES Irritable bowel syndrome patients displayed greater emotional expressiveness with negative prevalence. This reflects an emotional vulnerability potentially related to low regulation skills and underscores the importance of considering the central dysregulation hypothesis in IBS as a promising avenue of research.

An Initial Study of Alexithymia and Its Relationship With Cognitive Abilities Among Mild Cognitive Impairment, Mild Alzheimer's Disease, and Healthy Volunteers. J Nerv Ment Dis 2018; 206:628-636.

Abstract
The present study examined the degree to which alexithymia is greater in mild Alzheimer's disease (AD) and mild cognitive impairment (MCI) relative to healthy volunteers (healthy comparison [HC]), and investigated relationships between alexithymia and cognition. Eighty-five participants (MCI = 30, AD = 21, HC = 34) underwent a comprehensive neuropsychological examination and completed the 20-item Toronto Alexithymia Scale (TAS-20). Relative to HC, MCI and AD reported greater alexithymia total scores and higher scores on the TAS factor difficulty in identifying feelings (DIF). The remaining two factors, difficulty in describing feelings (DDF) and externally oriented thinking showed no significant group differences. In MCI, TAS-20 and DIF were negatively correlated with working and long-term verbal memory. In AD, TAS-20 was negatively correlated with general cognition, attention, memory, and visual spatial constructive and executive abilities. Also in AD, DIF was negatively correlated with general cognition, memory, and executive abilities. The correlation between DIF and long-term verbal memory in both MCI and AD suggests a potential common mechanism for alexithymia in these neurocognitive disorders. Declines in verbal memory may hinder a patient's ability to recall an association between a given sensation and the episodic experience of that sensation, thus leading to difficulty identifying feelings, as measured by the DIF factor of the TAS-20.

Front Psychol 2018; 9:453. [PMID: 29713295 PMCID: PMC5911526 DOI: 10.3389/fpsyg.2018.00453] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Accepted: 03/19/2018] [Indexed: 11/13/2022] Open
Abstract
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.

Abstract
Background: Alexithymia is a multifaceted personality construct that represents a deficit in the cognitive processing of emotions and is currently understood to be related to a variety of medical and psychiatric conditions. The present review aims to investigate the relationship of alexithymia with gastrointestinal (GI) disorders as functional gastrointestinal disorders (FGID, as irritable bowel syndrome (IBS) and functional dyspepsia) and inflammatory bowel disease (IBD) [ulcerative colitis (UC) and Crohn's disease (CD)] and liver diseases as chronic hepatitis C (CHC), cirrhosis, and liver transplantation. Methods: The articles were selected from the main electronic databases (PsycInfo, Medline, PubMed, Web of Science, Scopus, Cochrane, and ScienceDirect) using multiple combinations of relevant search terms (defined GI and liver diseases, articles in English, use of the Toronto scales [TAS] for alexithymia). The TAS was selected as inclusion criterion because it is the most widely used measure, thus allowing comparisons across studies. Results: Forty-eight studies met the inclusion criteria, of which 38 focused on GI disorders (27 on FGID and 11 on IBD) and 10 on liver diseases. Most studies (n = 30, 62%) were cross-sectional. The prevalence of alexithymia was higher in FGID (two third or more) than IBD and liver diseases (from one third to 50% of patients, consistent with other chronic non-GI diseases) than general population (10-15%). In functional disorders, alexithymia may be viewed as a primary driver for higher visceral perception, symptom reporting, health care use, symptom persistence, and negative treatment outcomes. Also, it has been found associated with psychological distress and specific GI-related forms of anxiety in predicting symptom severity as well as post-treatment outcomes and is associated with several psychological factors increasing the burden of disease and impairing levels of quality of life. A number of critical issues (small sample sizes, patients referred to secondary and tertiary care centers, cross-sectional study design, use of one single scale for alexithymia) constitutes a limitation to the generalization of findings. Conclusions: Alexithymia showed to play different roles in gastroenterology according to the clinical characteristics and the psychological burden of the various disorders, with main relevance in increasing subjective symptom perception and affecting negatively post-treatment outcomes.

Abstract
Pain in fibromyalgia (FM) is accompanied by a heterogeneous series of other symptoms, which strongly affect patients’ quality of life and interfere with social and work performance. The present study aimed to evaluate the effects of alexithymia on both the physical and the psychosocial components of the health-related quality of life (HRQoL) of FM patients, controlling for the concomitant effects of depression, anxiety, and pain. In particular, given the strong interconnection between depression and alexithymia, the relationship between alexithymia and HRQoL as mediated by depressive symptoms was further investigated. Data were collected on a consecutive sample of 205 female patients with a main diagnosis of FM. The results showed that about 26% of the patients showed the presence of alexithymia, as assessed by the Toronto Alexithymia Scale (TAS-20). Clinically relevant levels of depressive and anxiety symptoms were present in 61 and 60% of the patients, respectively. The results of the hierarchical multiple regression analyses showed that pain intensity (PI) and depressive symptoms explained the 45% of the variance of the physical component of HRQoL (p < 0.001). Regarding the mental component of HRQoL, depressive and anxiety symptoms, alexithymia, and PI significantly explained 61% of the variance (p < 0.001). The mediation analyses confirmed that alexithymia had a direct effect on the mental component of HRQoL and showed a statistically significant indirect effect on both the physical and the mental components, through the mediation of depressive symptoms. In conclusion, the results of the present study suggested the presence of both a direct and an indirect effect of alexithymia, in particular of the difficulty identifying feeling, on the HRQoL of patients with FM. Indeed, even though the concomitant presence of depressive symptoms is responsible of an indirect effect, alexithymia per se seems to directly contribute to worsen the impact that this chronic pain pathology has on the patients’ quality of life, especially regarding the psychosocial functioning.

Abstract
In the last few decades, particular attention has been paid to the role of personality specific traits that can affect the loss of health, i.e., Type D personality and Alexithymia. They have been conceptualized in a different period, this means that they are different both for their theoretical positions and their empirical studies. Some authors have speculated that there is a potential conceptual overlap between Type D personality and alexithymia constructs but there is a shortcoming in the literature. The aim of the study was to examine the potential overlap between the constructs of type D personality and alexithymia, replicating previous two studies, to extend these findings to Italian population. The participants were 247 Italian adults (males = 43%), recruited in primary health care practices of Palermo. All participants did not have chronic diseases during tests administration. They ranged in age from 35 to 69 years old (M = 52.34 years, SD = 9.76). Participants were administered Type D Personality Scale (DS-14) and Toronto Alexithymia Scale (TAS-20). A series of confirmatory factor analyses was performed to evaluate the factorial structure underlying the TAS-20 and DS-14 items. Globally results showed that alexithymia and type D personality are distinct constructs, but they are also strictly positively related with each other. Negative affectivity (NA) was highly correlated with Difficulties in identifying feelings and Difficulties in describing feelings, while Social inhibition (SI) was highly correlated with Difficulties in describing feelings. These results are consistent with those of other studies conducted in this area. Future research should consider evaluating the relationship between a deficit of affect regulation and type D personality to improve the effectiveness of interventions of health cure.

Abstract
INTRODUCTION Individuals with IBS report higher levels of psychological distress compared to healthy controls. Distress has been associated with emotional processing difficulties but studies have not explored how the relationship between distress and emotional processing affects IBS. There is little research on the role of positive affect (PA) in IBS. AIMS (a) If difficulties in self-reported emotional processing are associated with affect and IBS measures (i.e., symptom severity, interference in life roles) (b1) If affect mediates the relationship between emotional processing and IBS measures (b2) Alternative model: if affect mediates the relationship between IBS and emotional processing (c) If PA moderates the relationship between distress and IBS. METHODS Participants with a confirmed diagnosis of IBS (n=558) completed a questionnaire including measures of emotional processing (i.e., unhelpful beliefs about negative emotions, impoverished emotional experience), distress, PA, and IBS symptoms/interference. Mediation and moderation analyses were conducted with Maximum Likelihood Estimation. RESULTS Distress and PA mediated or partly mediated the relationship between unhelpful beliefs about negative emotions/impoverished emotional experience and both IBS measures. The alternative models were also valid, suggesting a two-way relationship between emotional processing and IBS through affect. PA did not moderate the relationship between distress and IBS. CONCLUSION Future interventions in IBS may benefit from not only targeting the management of physical symptoms and their daily impact but also aspects related to the experience of both negative and positive affect, and the acceptance and expression of negative emotions. Longitudinal studies are needed to confirm causal relationships within the explored models.

Abstract
OBJECTIVE To investigate the illness perception characteristics of Chinese patients with functional gastrointestinal disorders (FGID), and the mediating role between symptoms, psychopathology, and clinical outcomes. METHODS Six illness groups from four outpatient departments of a general hospital in China were recruited, including the FGID patient group. The modified and validated Chinese version of the illness perception questionnaire-revised was utilized, which contained three sections: symptom identity, illness representation, and causes. The 12-item short-form health survey was utilized to reflect the physical and mental health-related quality of life (HRQoL). The Toronto alexithymia scale was used to measure the severity of alexithymia. Additional behavioral outcome about the frequency of doctor visits in the past 12 months was measured. Pathway analyses with multiple-group comparisons were conducted to test the mediating role of illness perception. RESULTS Overall, 600 patients were recruited. The illness perceptions of FGID patients were characterized as with broad non-gastrointestinal symptoms (6.8 ± 4.2), a negative illness representation (more chronic course, worse consequences, lower personal and treatment control, lower illness coherence, and heavier emotional distress), and high numbers of psychological and culture-specific attributions. Fit indices of the three hypothesized path models (for physical and mental HRQoL and doctor-visit frequency, respectively) supported the mediating role of illness perceptions. For example, the severity of alexithymia and non-gastrointestinal symptoms had significant negative effect on mental quality of life through both direct (standardized effect: -0.085 and -0.233) and indirect (standardized effect: -0.045 and -0.231) influence via subscales of consequences, emotional representation, and psychological and risk factor attributions. Multi-group confirmatory factor analysis showed similar psychometric properties for FGID patients and the other disease group. CONCLUSION The management of FGID patients should take into consideration dysfunctional illness perceptions, non-gastrointestinal symptoms, and emotion regulation.

Abstract
Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder. Macroanalysis is a helpful tool for identifying the relationships between biological and psychosocial variables and the individual targets for medical intervention. The personalized and holistic approach to the patient includes integration of medical and psychological therapies in all phases of illness. In this respect, the development of a new psychotherapeutic modality, Well-Being Therapy, seems to be promising. The growth of subspecialties, such as psychooncology and psychodermatology, drives towards the multidisciplinary organization of health care to overcome artificial boundaries. There have been major transformations in health care needs in the past decades. From psychosomatic medicine, a land of innovative hypotheses and trends, many indications for changes in the current practice of medicine are now at hand. The aim of this critical review is to outline current and potential clinical applications of psychosomatic methods.

Abstract
Alexithymia is a clinically relevant personality construct characterized by difficulties identifying and describing feelings, externally oriented thinking, and impoverished imaginal processes. Previous taxometric investigations provided evidence that alexithymia is best conceptualized as a continuous dimension rather than a discrete type, at least when assessed with the self-report 20-Item Toronto Alexithymia Scale. The aim of the current study was to test the categorical versus dimensional structure of alexithymia using the recently developed Toronto Structured Interview for Alexithymia. Three nonredundant taxometric procedures (MAXCOV, MAMBAC, and L-Mode) were performed on the Toronto Structured Interview for Alexithymia subscale scores from a multinational sample of 842 adults. All taxometric procedures produced unambiguously dimensional solutions, providing further evidence that the core alexithymia features are continuously distributed in the population. Discussion focuses on the theoretical, assessment, and clinical implications of these findings for the alexithymia construct.

Abstract
In a previous investigation irritable bowel syndrome (IBS) was associated more to alexithymia than gastrointestinal-specific anxiety (GSA). In this study their independent contribution in predicting treatment outcome was longitudinally investigated. Consecutive 150 IBS patients were evaluated for IBS symptoms, alexithymia, GSA, and psychological distress with validated scales after as-usual treatment for 6-12months. The primary treatment outcome was improvement measured with the IBS-Severity Scoring System that showed 111 patients who improved and 39 who did not improve. Improvement was associated to both alexithymia (d=1.27) and GSA (d=4.63) but only alexithymia showed overtime stability by hierarchical regression, controlled for co-variables. A series of logistic and linear regressions showed that baseline alexithymia, but not GSA, independently predicted both post-treatment improvement status (Cox & Snell R2=0.15; overall classification rate=74%) and symptom change (23% of explained variance). Although alexithymia and GSA were closely related IBS symptoms, only alexithymia was found to be a stable trait and a stronger predictor of treatment outcome than GSA. Since no treatment was established to be definitely effective for IBS, clinicians might improve treatment outcome by identifying patients with high alexithymia, attempting to improve their coping skills, emotional regulation, and affective awareness.

Abstract
The Diagnostic and Statistical of Mental Disorders, Fifth Edition (DSM-5) somatic symptom and related disorders chapter has a limited clinical utility. In addition to the problems that the single diagnostic rubrics and the deletion of the diagnosis of hypochondriasis entail, there are 2 major ambiguities: (1) the use of the term "somatic symptoms" reflects an ill-defined concept of somatization and (2) abnormal illness behavior is included in all diagnostic rubrics, but it is never conceptually defined. In the present review of the literature, we will attempt to approach the clinical issue from a different angle, by introducing the trans-diagnostic viewpoint of illness behavior and propose an alternative clinimetric classification system, based on the Diagnostic Criteria for Psychosomatic Research.

Abstract
OBJECTIVE Alexithymia and depressive mood have been described as important dimensions of several medical diseases. Systemic lupus erythematosus is a chronic condition characterized by unpredictable clinical manifestations. The relationships between alexithymia, depression, and illness perception were examined in systemic lupus erythematosus patients. The interrelationships between psychological factors, such as alexithymia and depressive mood, were explored in systemic lupus erythematosus patients, and associations between these factors and illness perception in SLE were examined. We hypothesized that alexithymia and negative perceptions of illness would be associated in SLE patients, and depression would mediate this relationship. METHODS Subjects were 100 consecutive systemic lupus erythematosus patients attending the outpatient clinic at the University of Pisa rheumatology unit. They completed the Toronto Alexithymia Scale, Beck Depression Inventory, and Revised Illness Perceptions Questionnaire. Clinical variables were measured, disease activity was evaluated using the European Consensus Lupus Activity Measure, and damage was assessed using the Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index. RESULTS There were no associations between clinical variables, alexithymia, and depression. The results highlight the existence of significant links between alexithymia and illness perception for systemic lupus erythematosus patients. Moreover, our data suggest that some of these links are mediated by depression, which is the direct predictor of different aspects of perceived health. CONCLUSION Our findings suggest that studying the role of psychological factors, such as alexithymia and depression, may contribute to a more comprehensive perspective of systemic lupus erythematosus, including their impact on patients' beliefs about treatment effectiveness and emotional adaptation to chronic disease.

Abstract
Irritable bowel syndrome (IBS) has been recognized as one of the most common and best studied disorders among the group of functional gastrointestinal disorders. It is a functional bowel disorder in which abdominal pain or discomfort is associated with defecation or a change in bowel habit. In the Western world, IBS appears to affect up to 20% of the population at any given time but in Asian countries, the median value of IBS prevalence defined by various criteria ranges between 6.5% and 10.1%, and community prevalence of 4% is found in North India. Those attending gastroenterology clinics represent only the tip of the iceberg. The disorder substantially impairs the quality of life, and the overall health-care costs are high. IBS has therefore gained increased attention from clinicians, researchers, and pharmaceutical industries. It is often frustrating to both patients and physicians as the disease is usually chronic in nature and difficult to treat. However, the understanding of IBS has been changing from time to time and still most of its concepts are unknown. In this review we have discussed, debated, and synthesized the evidence base, focusing on underlying mechanisms in the brain and bowel. We conclude that it is both brain and bowel mechanisms that are responsible. The clinical implication of such mechanisms is discussed.

Abstract
OBJECTIVE Understanding the neural circuitry of placebo analgesia in the context of visceral pain is increasingly important given evidence of clinical benefit of placebo treatment in IBS. This functional MRI study addressed placebo analgesia in IBS, UC and healthy control (HC) volunteers. DESIGN Painful rectal distensions were delivered in N=17 patients with IBS , N=15 patients with UC in remission, and sex-matched and age-matched HCs in an adaptation phase followed by intravenous application of saline combined with either positive instructions of pain relief (placebo) or neutral instructions (control). Neural activation during cued-pain anticipation and pain was analysed along with ratings of expected and perceived pain and measures of negative affectivity and salivary cortisol concentrations. Correlational analyses between placebo analgesia responses and negative affect were accomplished. RESULTS HC and UC revealed significant pain inhibition during placebo analgesia, as evidenced by reduced neural activation in pain-related brain areas. In contrast, patients with IBS failed to effectively engage neural downregulation of pain, as evidenced by the absence of placebo-induced changes in distension-induced brain activation, resulting in a significant group difference in the cingulate cortex compared with HC. Depression scores correlated with weaker placebo analgesia, whereas state and trait anxiety were not associated. CONCLUSIONS Patients with IBS failed to effectively engage neural downregulation of rectal distension-induced pain during placebo analgesia, indicating a specific deficit in cognitive pain inhibition, which may in part be mediated by depression.

Abstract
The purpose of this paper is to review the current literature regarding the development of alexithymic personality features. Modern brain imaging technologies provide interesting data on the associations of alexithymia with different aberrations in brain function related to emotion regulation; however, the development of these deviations is poorly understood. A notable amount of research covers the relation of alexithymia to different environmental factors. Many of these associations, for example, with low socio-economic status and general psychopathology in childhood, are well established. However, the retrospective and cross-sectional designs commonly used in these studies, as well as the use of self-report measures, hinder the ability to firmly establish causality. Certain individual developmental factors, such as lagging speech development and congenital cardiac malformations in childhood, have been associated with the development of alexithymia. Regarding the stability of alexithymia, a systematic review of the literature was conducted for this paper. In addition to being characterized as a personality feature in the general population, alexithymia also clearly has a state-like dimension that results in increases and decreases in alexithymic features in conjunction with mental disorder symptoms. An essential question is whether the alexithymic features in adulthood are, in fact, infantile features of a restricted ability to identify and describe emotions that simply persist in individuals through adolescence to adulthood. To firmly establish the roots of alexithymia development, longitudinal studies, particularly in younger populations, are needed. Furthermore, multifaceted study settings are encouraged.

Abstract
OBJECTIVE Gastrointestinal-specific anxiety (GSA) and alexithymia are two psychological constructs that may contribute to severity of irritable bowel syndrome (IBS). We aimed to investigate their independent contribution in predicting the level of severity in a group of patients with moderate to severe IBS. METHOD A sample of 177 consecutive IBS patients (49.2% with moderate and 50.8% with severe IBS), diagnosed with Rome III criteria, were evaluated for IBS symptoms, alexithymia, GSA, psychological distress, and psychosocial functioning with validated scales. RESULTS IBS severity was highly associated to both alexithymia (r=0.61) and GSA (r=0.66), that were also associated to each other (r=0.64). Severe IBS patients scored significantly different than moderate IBS patients to all scales in the expected direction. Multiple and hierarchical regression analyses showed that IBS severity was predicted at a similar degree by alexithymia and GSA, controlled for IBS symptoms, psychological distress, and psychosocial functioning. Effect sizes showed that the highest IBS severity scores were obtained by patients with high alexithymia alone (d=1.16) or combined with higher GSA (d=1.45). CONCLUSION Alexithymia and GSA were closely related to each other and associated to IBS severity, thus suggesting a common basis of emotional dysregulation. However, alexithymia (particularly the facets of difficulty identifying and describing feelings) resulted to be a stronger predictor of IBS severity than GSA, thus suggesting that impaired affective awareness may reflect on the clinical manifestations of IBS.

Abstract
Alexithymia, a deficit characterized by difficulties identifying, differentiating, and articulating emotions, is associated with significant physical and mental health impairment. It is generally accepted that alexithymia has a negative impact on a variety of physical and mental health treatments. Less clear is the extent to which alexithymia itself can be modified. In this article we review studies that have examined the effects of psychological interventions on alexithymia. Taken together, findings from investigations included in this review suggest that alexithymia is partly modifiable with therapeutic interventions. Studies that directly targeted alexithymic symptoms tended to report significant reductions in alexithymia scores following treatment, whereas studies that measured changes in alexithymia but did not employ any psychological interventions specifically intended to treat alexithymia had more inconsistent results. We close by considering the practical implications of the findings, and by offering suggestions for future research.

Abstract
Objectives The aim of the study was to evaluate the presence of alexithymia in a group of patients with endometriosis and chronic pelvic pain, and compare the results obtained, with those for a group of healthy controls. Methods Forty-one patients with pain and surgical diagnosis of deep endometriosis and 40 healthy controls were recruited for the study. All subjects were assessed using the Toronto Alexithymia Scale (TAS-20). Moreover, the intensity of chronic pelvic pain and dysmenorrhea in patients was evaluated using a modified version of the Biberoglu-Behrman pain scale. In addition, the patients' state of general health was investigated with the SF-36. Results A positive score for alexithymia was achieved in 14.6% (n = 6) of patients with endometriosis, while the condition was absent in the control group. Alexithymia was indeterminate in 29.3% (n = 12) and 12.5% (n = 5) of patients and controls, respectively, and absent in 56.1% (n = 22) and 87.5% (n = 35). Intergroup differences were significant for 3 factors evaluated by the TAS-20. Discussion The present study underlined how women with endometriosis are significantly more alexithymic compared with controls.

Abstract
BACKGROUND Despite the availability of highly efficacious treatments, many individuals with anxiety disorders never receive adequate treatment. Alexithymic deficits, such as difficulties in recognizing feelings and focusing on emotional experiences, may contribute to low rates of help seeking. METHODS Multiple Internet-based strategies (announcements of anxiety disorder websites, postings in online self-help forums, notices in anxiety chat rooms) were used to recruit a sample of 312 participants with chronic and clinically relevant anxiety symptoms. Those who had never received professional treatment (n = 49) were compared to those with current or previous treatment (n=263) with regard to alexithymia, anxiety, depression and health-related quality of life. RESULTS Logistic regression analysis revealed that the strongest predictor for belonging to the never treated group was the externally oriented thinking facet of alexithymia. In addition, substantially more participants in the never treated group (49%) were considered high-alexithymic (20-item Toronto Alexithymia Scale total score ≥ 61) compared to the treated group (35%). CONCLUSIONS The main finding was a strong relationship between the externally oriented thinking facet of alexithymia and the non-use of professional help for anxiety. Internet-based programs could be a promising first step in supporting this group of people to overcome their anxiety.

Abstract
OBJECTIVE This study explored the role of psychosocial factors in predicting both membership to either an irritable bowel syndrome (IBS) or control group, and the severity of IBS symptoms. METHODS A total of 149 participants (82 IBS and 67 controls) completed a battery of self-report inventories assessing disposition and environment, cognitive processes, and psychological distress. Logistic regression analyses were used to assess predictive contribution of psychosocial variables to IBS diagnosis. Hierarchical linear regression was then used to assess the relationship of psychosocial variables with the severity of IBS symptoms. RESULTS Significant predictors of IBS were found to be alexithymia, the defectiveness/shame schema, and four coping dimensions (active coping, instrumental support, self-blame, and positive reframing), χ(2) (6, N=130)=46.99, p<.001, with predictive accuracy of 72%. Significant predictors of IBS symptom severity were two of the alexithymia subscales (difficulty identifying feelings, and difficulty describing feelings), gender, the schemas of defectiveness/shame and entitlement, and global psychological distress. This model predicted IBS severity F (6, 64)=16.94, p<.001 and accounted for 61.3% of the variability in IBS severity scores. CONCLUSION Psychosocial variables account for a large percentage of the differences between an IBS and control group, as well as the variance of symptoms experienced within the IBS group. Alexithymia and the defectiveness schema appear to be related to both IBS and symptom severity.

Abstract
OBJECTIVE To use the Diagnostic Criteria for Psychosomatic Research (DCPR) for characterizing alexithymia in a large and heterogeneous medical population, in conjunction with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and other DCPR criteria. METHOD Of 1305 patients recruited from 4 medical centers in the Italian Health System, 1190 agreed to participate. They all underwent an assessment with DSM-IV and DCPR structured interviews. A total of 188 patients (15.8%) were defined as alexithymic by using the DCPR criteria. Data were submitted to cluster analysis. RESULTS Five clusters of patients with alexithymia were identified: (1) alexithymia with no psychiatric comorbidity (29.3% of cases); (2) depressed somatization with alexithymic features (23.4%); (3) alexithymic illness behavior (17.6%); (4) alexithymic somatization (17%) and (5) alexithymic anxiety (12.8%). CONCLUSIONS The results indicate that DCPR alexithymia is associated with a comorbid mood or anxiety disorder in about one third of cases; it is related to various forms of somatization and abnormal illness behavior in another third and may occur without psychiatric comorbidity in another subgroup. Identification of alexithymic features may entail major prognostic and therapeutic differences among medical patients who otherwise seem to be deceptively similar since they share the same psychiatric and/or medical diagnosis.

Abstract
Purpose To investigate the connection between alexithymia and somatic illness, or, somatization, in veterans suffering from chronic combat-related post-traumatic stress disorder, PTSD. Methods Croatian combat veterans (N=127) were studied at the Department of Psychology, Zagreb Clinical Hospital Center. The diagnosis of PTSD was confirmed and verified according to the International Classification of Diseases (ICD-10). A version of the Mississippi Scale for Combat Related PTSD (M-PTSD) standardized for the Croatian population was used to assess the severity of PTSD. In addition to the clinical interview, the existence of alexithymia was confirmed by the score on the Toronto Alexithymia Scale (TA S-20). Results A statistically significant association was found between the total number of diagnosed physical illnesses and the scores on three subscales of an alexithymia questionnaire, the TA S-20, with a 1% risk (p<0.01, 0.487; 0.450; 0.335). Regression analysis confirmed the most statistically significant predictive value of the first item of the TA S-20, which refers to difficulty in identifying feelings (=0.408, p=0.019). The total score on the M-PTSD scale correlated significantly to the subscales for alexithymia. There was a statistically significant negative correlation of the total score on the M-PTSD scale with social support. Conclusion The total scores obtained in this study, particularly those related to alexithymia, indicate the importance of this construct in the etiopathogenesis of somatic morbidity in the study population and confirm that as in other countries the TA S-20 is a useful instrument in Croatia for the assessment of this phenomenon.

Abstract
The Diagnostic Criteria for Psychosomatic Research (DCPR) were introduced in 1995 by an international group of investigators to expand the traditional domains of the disease model. The DCPR are a set of 12 'psychosomatic syndromes' which provide operational tools for psychosocial variables with prognostic and therapeutic implications in clinical settings. Eight syndromes concern the main manifestations of abnormal illness behaviour: somatization, hypochondriacal fears and beliefs, and illness denial. The other four syndromes (alexithymia, type A behaviour, demoralization and irritable mood) refer to the domain of psychological factors affecting medical conditions. This review describes the conceptual bases of the DCPR and the main findings concerning their application, with particular reference to the incremental information they added to the customary psychiatric classification. The DCPR were also compared with the provisional DSM-5 somatic symptom disorders. The DCPR were found to be more sensitive than DSM-IV in identifying subthreshold psychological distress and characterizing patients' psychological response to medical illness. DSM-5 somatic symptom disorders seem to neglect important clinical phenomena, such as illness denial, resulting in a narrow view of patients' functioning. The additional information provided by the DCPR may enhance the decision-making process.
