Abstract
INTRODUCTION This study aimed to examine the relationships between dissociative and somatic symptoms and how they might contribute to PTSD severity among ex-soldiers who sought help from the IDF Combat Stress Reaction Unit (CSRU). MATERIALS AND METHODS This cross-sectional study included 1,305 former compulsory, career, and reserve soldiers, who filled out self-report questionnaires on admission for evaluation at the CSRU. The study's dependent variables included two posttraumatic stress disorder measures (CAPS and PCL-5). The independent variables were the Dissociative Experience Scale and Brief Symptom Inventory. Background and service-related variables were also examined. RESULTS Spearman correlation revealed that the higher the level of somatization is, the higher the level of PTSD via PCL and CAPS. A significant positive association was found between somatization and dissociation (r = 0.544; P < 0.001). The higher the somatization level, the more severe the dissociation. A multivariate logistic regression analysis to predict severe PTSD revealed that the longer the time elapsed from the traumatic event (OR = 1.019, P = 0.015), the higher the risk for severe PTSD. The most prominent variables were dissociation (OR = 6.420, P < 0.001) and somatization (OR = 4.792, P < 0.001). The entire model reached 40.8% of the shared variance in the regression. CONCLUSIONS While there is direct reference to dissociation in the clinical assessment by PCL or CAPS, there is no such reference to somatization. Highly functioning combatants sometimes express their distress somatically. Our findings suggest regarding severe somatic symptoms as diagnostic criteria for PTSD.

Abstract
OBJECTIVE Personality, emotions, and olfaction exhibit partial anatomical overlap in the limbic system structure, establishing potential mechanisms between personality, affective disorders, and olfactory-related aspects. Thus, this study aims to investigate the associations among the Big Five personality traits, alexithymia, anxiety symptoms, and odor awareness. METHODS A total of 863 college participants were recruited for this study. All participants completed the Chinese Big Five Personality Inventory-15, the Odor Awareness Scale (OAS), the Toronto Alexithymia Scale-20, and the Generalized Anxiety Disorder Screener-7. Structural equation modeling was employed to examine the hypothesized mediated model. RESULTS The findings revealed the majority of significant intercorrelations among the dimensions of the Big Five personality traits, alexithymia, anxiety symptoms, and OAS (|r| = 0.072-0.567, p < 0.05). Alexithymia and anxiety symptoms exhibited a serial mediation effect between neuroticism and OAS (95%CI[0.001, 0.014]), conscientiousness and OAS (95%CI[-0.008, -0.001]), and extraversion and OAS (95%CI[-0.006, -0.001]). Anxiety symptoms mediated the relationship between agreeableness and OAS (95%CI[-0.023, -0.001]) and between openness and OAS (95%CI [0.004, 0.024]). CONCLUSION The mediating roles of alexithymia and anxiety symptoms between the Big Five personality traits and odor awareness support the idea of a certain level of association among personality, emotions, and olfaction, with the underlying role of the limbic system structure. This enhances our understanding of personality, emotions, and olfaction and provides insights for future intervention measures for affective disorders and olfactory dysfunctions.

Front Psychol 2024; 14:1317088.

Abstract
Objective Dissociation is a conscious state characterized by alterations in sensation and perception and is thought to arise from traumatic life experiences. Previous research has demonstrated that individuals with high levels of dissociation show impairments in cognitive-emotional processes. Therefore, using the Competing Neurobehavioral Decisions System (CNDS) theory, we used statistical modeling to examine whether dissociative experience and trauma symptoms are independently predicted by impulsivity, risk-seeking, affective state (i.e., anxiety, depression, stress, and negative affect), and trauma history. Method In this cross-sectional study design, data were collected via Amazon Mechanical Turk from a total of n = 557 English-speaking participants in the United States. Using Qualtrics, participants answered a series of self-reported questionnaires and completed several neurocognitive tasks. Three independent multiple linear regression models were conducted to assess whether impulsivity, risk seeking, affective state, and trauma history predict depersonalization, trauma symptoms, and PTSD symptoms. Results As hypothesized, we found that depersonalization and other trauma symptoms are associated with heightened impulsivity, increased risk-seeking, impaired affective states, and a history of traumatic experiences. Conclusion We demonstrate that an imbalanced CNDS (i.e., hyperimpulsive/hypoexecutive), as evidenced by decreased future valuation, increased risk seeking, and impaired affective states, predicts heightened depersonalization and other trauma and PTSD symptomatology. This is the first time that dissociation has been connected to delay discounting (i.e., the tendency to place more value on rewards received immediately compared to farther in the future). Interventions that positively impact areas of the CNDS, such as episodic future thinking or mindfulness meditation, may be a target to help decrease dissociative symptoms.

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
Ego dissolution (i.e., ego loss, ego disintegration, ego death, or self-loss) is a conscious state marked by a loss or diminution of one's sense of self and a lack of first-person experience. We developed a novel, valid, and internally consistent ego dissolution scale to both (a) assess trait-like aspects of ego dissolution, which have received scant attention to date, and (b) facilitate future research in a variety of contexts (e.g., personality, psychopathology, substance use/psychedelics, contemplative practices). We determined that the 10-item Ego Dissolution Scale (EDS; Cronbach's α = 0.80) and its identified subfactors of Ego-Loss (Cronbach's α = 0.84) and Unity (Cronbach's α = 0.75) were internally consistent, possessed strong convergent (e.g., depersonalization/derealization, mysticism, unusual experiences) and discriminant validity (e.g., neuroticism, social desirability). We found ego dissolution and dissociation to be empirically related yet discriminable on a statistical basis.

Subjective Impact of Age-Related Hearing Loss Is Worse for Those Who Routinely Experience Boredom and Failures of Attention. Ear Hear 2023; 44:199-208.

Abstract
OBJECTIVES Despite extensive evidence supporting the benefits of hearing treatments for individuals affected by hearing loss, many leave their hearing issues unaddressed. This underscores the need to better understand the individual factors influencing decision-making regarding hearing loss treatments. One consideration regarding the low uptake of treatment is the finding that the subjective impact of hearing loss is greater for some individuals than for others, yielding a significant discrepancy between subjective measures of hearing loss (e.g., self-report hearing-handicap scales) and objective audiometric assessments (e.g., audiograms). The current study seeks to elucidate some of the cognitive-affective factors that give rise to these individual differences in the subjective impact of hearing loss. Specifically, we hypothesized that a stronger trait tendency to experience boredom would be correlated with more intensely negative experiences of hearing-related issues, and that this relationship would be mediated by underlying attentional difficulties. METHODS Through a partnership with hearing care clinics (Connect Hearing Canada), we recruited a large sample of older adults (n = 1840) through their network of hearing-care clinics. Audiometric thresholds provided an objective measure of hearing ability for each participant, while self-report questionnaires assessed individual differences in the subjective impact of hearing-related issues (hearing handicap), subjective strain experienced when listening (listening effort), tendency to experience boredom, tendency to experience difficulty maintaining task-focused attention (mind-wandering), and self-perceived level of cognitive functioning. RESULTS The subjective impact of hearing loss-both in terms of hearing handicap and strain when listening-was found to be more intensely negative for those who are characteristically more susceptible to experiencing boredom, and this relationship was shown to be mediated by self-reported differences in the ability to maintain task-focused attention. This relationship between trait boredom proneness and the subjective impact of hearing-related issues was evident across all levels of objective hearing abilities. Moreover, there was no evidence that the subjective impact of hearing loss is worse for those who routinely experience boredom because of objectively-poorer hearing abilities in those individuals. CONCLUSIONS A greater trait susceptibility to experiencing boredom was associated with a more aversive subjective experience of hearing loss, and this relationship is mediated by attentional difficulties. This is a novel discovery regarding the cognitive-affective factors that are linked to individual differences in the effect that hearing loss has on individuals' daily functioning. These results may be helpful for better understanding the determinants of hearing-rehabilitation decisions and how to improve the uptake of treatments for hearing loss. The observational nature of the current study restricts us from drawing any definitive conclusions about the casual directions among the factors being investigated. Further research is therefore needed to establish how individual differences in the characteristic tendency to experience boredom are related to attentional-control difficulties and the experience of hearing-related issues. More research is also required to determine how all of these factors may influence decisions regarding hearing-loss treatments.

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

Abstract
OBJECTIVE In this study, we aimed to focus on the psychological aspect of unexplained infertility by comparing their psychological features to those of infertile patients with a known causes and fertile patients. PATIENTS AND METHODS Sixty unexplained infertility patients, 50 infertile patients with a known cause and 56 fertile patients were included in the study. Patients were evaluated using socio-demographic data form, Toronto Alexithymia Scale (TAS-20), Somatosensory Amplification Scale (SAS) and Anxiety Sensitivity Index (ASI-3). RESULTS No significant differences in the levels of alexithymia, somatosensory amplification and anxiety sensitivity were detected between the groups (P > .05). When the correlation of clinical scale scores with each other was analysed in the whole group of infertile patients regardless of the cause, a weak positive correlation was found between anxiety sensitivity and difficulty in identifying feelings. CONCLUSION In our study, it has been found out that; regardless of the knowledge of the aetiology of infertility, the levels of alexithymia, somatosensory amplification and anxiety sensitivity of infertile cases did not differ from those of fertile women. However, it has been shown that as the difficulty in identifying emotions increases in infertile cases, anxiety sensitivity, which may cause psychological infertility, also increases.

Abstract
Background Several factors are associated with the incidence of burnout, including alexithymia, social support, and depression. The relative importance of these three key parameters as mediators of burnout, however, is not well understood. In addition, there have been few studies to date specifically examining the association between alexithymia and burnout among nurses in China. Purpose To evaluate the relationship of burnout with alexithymia, social support, and depression across emergency department nurses in China. Methods This descriptive, cross-sectional survey was conducted using a convenience sampling methodology to survey nurses responsible for direct emergency care (n = 413) from 18 tertiary hospitals in Western, Eastern, Northern, and Southern China between May 2020 and June 2020. A structural equation modeling approach was then used to assess a hypothetical model wherein alexithymia both directly and indirectly affects burnout among emergency nurses via impacting the incidence of depression and perceived social support. Results Results supported all driving hypotheses. Alexithymia was positive direct correlated with burnout (β = 0.35; P < 0.001) and depression (β = 0.50; P < 0.001), and exhibited a negative direct effect on social support (β = − 0.14; P = 0.041). Depression was associated with burnout, both directly (β = 0.24; P < 0.001) and indirectly (β = 0.15; P < 0.001) through its relationship with social support. Alexithymia was the factor most strongly associated with burnout, and it was able to affect burnout indirectly through depression and social support. Conclusions We found that among emergency nurses in China, alexithymia was correlated with burnout, depression, and social support. Alexithymia was the factor most strongly associated with burnout. These data suggest that providing better social support and alleviating alexithymia may decrease rates of burnout among emergency nurses.

Abstract
Dissociative symptoms are common, possibly severe, side effects associated with the use of ketamine and esketamine in depression. We investigated the relationship between trait dissociation and dissociation induced by ketamine and esketamine used as augmentation therapy in treatment-resistant depression (TRD). Adults with TRD were randomly assigned to receive a single intravenous infusion, with a duration of 40 min, of either esketamine 0.25 mg/kg or ketamine 0.5 mg/kg. We assessed trait dissociation with the Dissociative Experience Scale (DES) and, to evaluate induced dissociation, the Clinician-Administered Dissociative States Scale (CADSS) was used. Thirty-two subjects received esketamine and 29 received ketamine. The groups had similar median DES scores (p = 0.26). More than 30% of the patients in both groups had DES scores ≥30 points. The median CADSS score in the esketamine group was equivalent to that in the ketamine group (p = 0.40). Every 5 points increment in the DES was associated with a 10.9% (95% CI 4.5-17.8%) increase in the CADSS, in an exponential fashion when the two groups were pooled together. Subjects with high trait dissociation had a higher risk of induced dissociation state (relative risk [RR] 1.41, 95% CI 1.11-1.78) and very high induced dissociation (RR 3.05, 95% CI 1.14-8.15). Induced dissociation was not a serious adverse effect. The findings suggest that trait dissociation is a predictor of induced dissociation by Ketamine or Esketamine in TRD subjects. Screening for trait dissociation and counseling patients with high trait dissociation on the risks of dissociation by these drugs are recommended.

OBJECTIVES Depersonalization-derealization (DEP-DER) is a dissociative experience which is related to psychopathology and distress. Yet, the aetiological factors leading to DEP-DER are not sufficiently clear. In this study, we suggest rumination as one possible antecedent. Thus, the goal of the study was to explore the longitudinal relationship between rumination and DEP-DER. DESIGN Longitudinal self-report study; mixed clinical and community sample. METHODS The study was conducted on 98 participants, 49 of them were diagnosed with depression, anxiety disorders, or obsessive-compulsive disorder, and the other 49 were healthy, matched community controls. The participants underwent a structured clinical interview and completed a battery of questionnaires. Then, the participants completed the same battery again once a month, for five additional assessment points (6 months in total). The data were analysed using multilevel linear modelling with time-lag analysis. RESULTS We found that levels of rumination and DEP-DER increased and decreased simultaneously, meaning that on assessments in which people reported that they tended to ruminate, they also reported higher levels of DEP-DER symptoms. In addition, we found support for a unidirectional association, consistent with our theoretical hypothesis. Specifically, rumination levels on a certain month longitudinally predicted a higher likeliness for reporting DEP-DER on the following month, even when controlling for the contemporaneous relationship. Conversely, DEP-DER symptoms did not longitudinally predict increased rumination. CONCLUSIONS These findings suggest that rumination may be an antecedent of DEP-DER, but not vice versa. Possible mechanisms to explain this link are discussed. PRACTITIONER POINTS Rumination and DEP-DER oscillate together over time; additionally, rumination predicts a longitudinal increase in DEP-DER. Clinicians noticing ruminative thought followed by decreased emotionality should distinguish between an authentic decrease of distress versus detachment. The findings provide one possible explanation for the frequency of DEP-DER symptoms in anxiety and depressive disorders. Poor sleep quality and emotion regulation difficulties should be explored as potential mediators explaining this link.

Abstract
Objective While it is well known that mental health problems are common consequences of deadly pandemics, the association with alexithymia is less clear. This study examined this association in an evaluation of home-quarantined university students during the 2019/2020 COVID-19 pandemic in China. Methods In total, 2501 home-quarantined students from six southwest Chinese universities completed the following questionnaires: the 20-item Toronto Alexithymia Scale (TAS-20), the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL—C), and the Patients Health Questionnaire-9 (PHQ-9), after which structural equation modeling (SEM) and mediation analyses were employed to extract and evaluate the possible associations. Results It was found that participants with probable depression or PTSD also reported more severe alexithymia features, such as difficulties in identifying feelings (DIF) or describing feelings (DDF). Alexithymia was also found to partially mediate the effect of number of exposures on mental health problems. Conclusion These results suggested that implementing strategies to assist young people identify and deal with their own emotions and those of others could prevent or mitigate the mental health problems associated with deadly pandemic events. However, future longitudinal studies are needed to examine the specific involvement of DIF or DDF in people with mental health problems.

Abstract
The association among alexithymia, somatic symptoms and clinical correlates has been scantly investigated in children. The present study examined alexithymic features and somatic symptomatology in schoolchildren with high and low levels of depression, testing the role of depressive symptoms in mediating the associations between alexithymia and somatic symptoms. Seven-hundred schoolchildren were involved in this study and divided into two subgroups (8-10 years and 11-14 years) in order to test differences according to the age. Participants completed the Children's Somatization Inventory-24 for the assessment of somatic symptoms, the Alexithymia Questionnaire for Children to evaluate alexithymic features and the Children's Depression Inventory-2 to investigate depressive symptoms. Results showed that children with high levels of depression reported both higher alexithymia and somatic symptoms levels. Despite a direct effect of alexithymia on somatic symptoms, the mediation analyses also highlighted an indirect effect of alexythimia on somatic symptoms through depressive symptoms. Findings suggested that a depressive symptomatology may clarify why schoolchildren with high alexithymia scores tend to report higher levels of health problems. Results also support the possibility that depressive symptoms may contribute to the development of somatic symptomatology among schoolchildren in the presence of high levels of alexithymia.

Abstract
Alexithymia and dissociation have been consistently linked in the literature, particularly in psychiatric populations. Both arise from a disconnection between conscious aspects of self-experiences and perceptions at both the mental self and bodily levels. This results in difficulty integrating thoughts, feelings and experiences into consciousness and memory, negatively impacting emotion awareness/regulation and reflective functioning. We conducted a meta-analysis to examine the strength of the relationship between alexithymia and dissociation in both clinical and non-clinical populations. Studies using two common measures of these constructs were included (i.e., the Toronto Alexithymia Scale - TAS, and the Dissociative Experiences Scale - DES). Analyzing the effect sizes derived from 19 studies (including a total of 4664 participants) revealed moderate to strong relationships between alexithymia and dissociation. The strength of the association was higher in clinical and younger aged non clinical populations. These findings are discussed in the context of treatment recommendations..

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.

Abstract
OBJECTIVES Previous research on alexithymia has led to controversy over its prevalence in panic disorder. The aim of this study was to assess the difference in the prevalence of alexithymia in panic disorder and other anxiety disorders. DESIGN AND METHODS We performed a cross-sectional study on a sample of 71 patients diagnosed with panic disorder and 113 patients diagnosed with other anxiety disorders; both groups were 18-50 years old. Primary outcome was the 20-item Toronto Alexithymia Scale (TAS) score. Secondary outcome was the prevalence of alexithymia defined as a TAS score ≥61. RESULTS Patients diagnosed with panic disorder had a 25% higher score on the TAS subscale of difficulty identifying feelings than patients diagnosed with other anxiety disorders. The prevalence of alexithymia was 27% in patients with panic disorder and 13% in patients with other anxiety disorders. Patients diagnosed with panic disorder had significantly higher odds for alexithymia. CONCLUSIONS The results of our study support the hypothesis of higher prevalence of alexithymia in individuals with panic disorder than in individuals with other anxiety disorders. In addition, difficulty identifying feelings as a salient feature of alexithymia is higher in panic disorder than in other anxiety disorders.

Abstract
Several short-term pathways have been implicated in relation to dissociative experiences, among them are daily stress, sleepiness, and rumination. In addition, it has been claimed that mechanisms contributing to dissociative experiences may differ, according to specific psychopathological symptoms. Accordingly, this study had two aims. The first was to sample moment-to-moment increases or decreases in current stress, sleepiness, and rumination, in order to assess their temporal relations with state dissociation. Rumination was broken down to its basic two subcomponents: the negative value of the thoughts and thinking about the past (in comparison to present or future), in order to differentiate it from other repetitive thought patterns (e.g., worry). The second goal was to explore whether depression, anxiety, and obsessive–compulsive symptoms may moderate the links between the three mechanisms and specific state dissociation scales [specifically, depersonalization-derealization (DEP-DER) and absorption (ABS)]. Ninety-nine undergraduate students completed trait questionnaires and then answered state items four times a day for 4 days. These experience sampling data were analyzed using multilevel linear modeling (MLM) with Level 1 state measurements and Level 2 demographic and trait variables of the participants. Moments of stress, sleepiness, thinking about the past and negative thoughts were all associated both with state DEP-DER and with state ABS. Dissociation, negative thinking, stress, and sleepiness were positively associated with moments of thinking about the past and the future but inversely associated with moments of thinking about the present. Finally, in accordance with our expectations, the links between DEP-DER and hypothesized mechanisms were mostly moderated by depression and anxiety symptoms, whereas the links between ABS and hypothesized mechanisms were moderated mainly by obsessive–compulsive symptoms. Our findings are in accordance with literature on the efficacy of mindfulness as well as the maladaptive correlates of mind-wandering, as they suggest that dissociative detachment from one’s present occupation is associated with decreased well-being.

Abstract
OBJECTIVE Alexithymia, neuroticism, and extraversion have been described as relevant predictors of mental and physical health conditions, but their putative interactive effects remain poorly understood and their prospective effects are not well studied. The present study has investigated the differential contributions of distinct personality traits in predicting mental and somatic health symptoms in cross-sectional and longitudinal analyses. METHODS Additive and interactive effects of neuroticism and extraversion (NEO-FFI), the TAS-20 total score (20-Item Toronto Alexithymia Scale) and its factors (Difficulty Identifying Feelings (DIF), Difficulty Describing Feelings (DDF) and External Oriented Thinking (EOT)) have been investigated on depressive symptoms, the number of chronic diseases, somatic and mental subjective health complaints. Analyses have been based on data from the population-based "Study of Health in Pomerania" (SHIP) in cross-sectional (N = 1704) and longitudinal (N = 1244) analyses. RESULTS In cross-sectional and longitudinal analyses, additive associations of the TAS-20 total score and neuroticism on somatic and mental health complaints have been observed. The effects of the TAS-20 total score have been mainly carried by DIF. Further, in interaction effetcs extraversion has attenuated the negative impact of neuroticism, whereas DIF has augmented it. CONCLUSION The present study is the first demonstrating longitudinal effects of alexithymia, particularly DIF, neuroticism, and extraversion in predicting mental and somatic health symptoms. Associations between DIF, neuroticism, and extraversion have been additive and interactive. Hence, subjects high in neuroticism and DIF but low in extraversion have reported most health symptoms and thus might be in need for prevention strategies. Treatments chould be adapted to the associated combination of the personality characteristics.

Abstract
BACKGROUND Life events (LEs) are associated with future physical and mental health. They are crucial for understanding the pathways to mental disorders as well as the interactions with biological parameters. However, deeper insight is needed into the complex interplay between the type of LE, its subjective evaluation and accompanying factors such as social support. The "Stralsund Life Event List" (SEL) was developed to facilitate this research. METHODS The SEL is a standardized interview that assesses the time of occurrence and frequency of 81 LEs, their subjective emotional valence, the perceived social support during the LE experience and the impact of past LEs on present life. Data from 2265 subjects from the general population-based cohort study "Study of Health in Pomerania" (SHIP) were analysed. Based on the mean emotional valence ratings of the whole sample, LEs were categorized as "positive" or "negative". For verification, the SEL was related to lifetime major depressive disorder (MDD; Munich Composite International Diagnostic Interview), childhood trauma (Childhood Trauma Questionnaire), resilience (Resilience Scale) and subjective health (SF-12 Health Survey). RESULTS The report of lifetime MDD was associated with more negative emotional valence ratings of negative LEs (OR = 2.96, p < 0.0001). Negative LEs (b = 0.071, p < 0.0001, β = 0.25) and more negative emotional valence ratings of positive LEs (b = 3.74, p < 0.0001, β = 0.11) were positively associated with childhood trauma. In contrast, more positive emotional valence ratings of positive LEs were associated with higher resilience (b = - 7.05, p < 0.0001, β = 0.13), and a lower present impact of past negative LEs was associated with better subjective health (b = 2.79, p = 0.001, β = 0.05). The internal consistency of the generated scores varied considerably, but the mean value was acceptable (averaged Cronbach's alpha > 0.75). CONCLUSIONS The SEL is a valid instrument that enables the analysis of the number and frequency of LEs, their emotional valence, perceived social support and current impact on life on a global score and on an individual item level. Thus, we can recommend its use in research settings that require the assessment and analysis of the relationship between the occurrence and subjective evaluation of LEs as well as the complex balance between distressing and stabilizing life experiences.

Abstract
PURPOSE Individuals with trait alexithymia (AL) display poor cognitive assimilation of thoughts, feelings, and emotions. This may result in the persistence of stress, anxiety, and depressive disorders. The cumulative effect of this psychological distress is also linked clinical markers of human immunodeficiency virus (HIV) disease progression. This study examines the indirect effect of AL on HIV viral load as a function of baseline levels and change in psychological distress. METHODS N = 123 HIV positive adults aged 37.9 ± 9.2 years provided blood samples for HIV-1 viral RNA and CD4 T lymphocytes along with self-reported stress, anxiety, and depression every 6 months for 2 years. A second-order conditional latent growth model was used to represent baseline and 2-year change in cumulative levels of psychological distress and to test the indirect effect of baseline levels of trait AL on change in HIV-1 viral load through this latent measure. RESULTS AL was associated with baseline and latent change in psychological distress. Furthermore, baseline psychological distress predicted 2-year change in HIV-1 viral RNA after controlling for viral load at baseline. Altogether, trait AL had a significant indirect effect on change in viral load (β = 0.16, p = 0.03) as a function of baseline levels of distress. CONCLUSION Identification and communication of thoughts, feelings, and emotions are important for long-term psychological adaptation in HIV. Greater psychological distress, in turn, allows for persistence of peripheral viral replication.

Abstract
BACKGROUND The aim of this study was to explore whether certain aspects of emotion dysregulation (i.e., facets of alexithymia and rumination) are more closely linked to hypochondriasis than to depression and vice versa. METHODS Nineteen patients with hypochondriasis (HYP), 33 patients with depression, and 52 healthy control participants completed the Toronto Alexithymia Scale, the Response Styles Questionnaire, and additional symptom and illness behaviour scales. A clinical interview was used to establish DSM-IV diagnoses and to exclude all cases with more than one axis I diagnosis. RESULTS Depression patients reported more difficulties describing feelings and more symptom- and self-focused rumination than both HYP patients and healthy individuals, whereas HYP patients differed only from healthy individuals in regard to more difficulties in identifying feelings and more symptom-focused rumination. Multiple regression analyses, including all assessed facets of emotion dysregulation, showed that the degree of somatoform features (somatic symptoms, health anxiety, and illness behaviour) was specifically predicted by higher difficulties in identifying feelings scores, whereas depressive symptom levels were specifically predicted by higher rumination scores. CONCLUSIONS Specific associations were found between difficulties in identifying feelings and key features of HYP, whereas depression was linked to a more generalized pattern of emotion regulation deficits. KEY PRACTITIONER MESSAGE Emotion dysregulation can be found in hypochondriasis and depression Difficulties in identifying own feelings are specifically linked to somatic symptoms, health anxiety, and illness behaviour, whereas a more generalized pattern of emotion dysregulation is found in relation to depression Further research is needed to investigate whether the effectiveness of current treatments for depression, hypochondriasis, health anxiety, and related disorders could be improved by additional emotion regulation interventions.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) and depression co-occur frequently following the experience of potentially traumatizing events (PTE; Morina et al., 2013). A person-centered approach to discern heterogeneous patterns of such co-occurring symptoms is recommended (Galatzer-Levy and Bryant, 2013). We assessed heterogeneity in PTSD and depression symptomatology; and subsequently assessed relations between class membership with psychopathology constructs (alcohol use, distress tolerance, dissociative experiences). METHODS The sample consisted of 268 university students who had experienced a PTE and susequently endorsed clinical levels of PTSD or depression severity. Latent profile analyses (LPA) was used to identify the best-fitting class solution accouring to recommended fit indices (Nylund et al., 2007a); and the effects of covariates was analyzed using a 3-step approach (Vermunt, 2010). RESULTS Results of the LPA indicated an optimal 3-class solutions: high severity (Class 2), lower PTSD-higher depression (Class 1), and higher PTSD-lower depression (Class 3). Covariates of distress tolerance, and different kinds of dissociative experiences differentiated the latent classes. LIMITATIONS Use of self-report measure could lead to response biases; and the specific nature of the sample limits generalizability of results. CONCLUSION We found evidence for a depressive subtype of PTSD differentiated from other classes in terms of lower distress tolerance and greater dissociative experiences. Thus, transdiagnostic treatment protocols may be most beneficial for these latent class members. Further, the distinctiveness of PTSD and depression at comparatively lower levels of PTSD severity was supported (mainly in terms of distress tolerance abilities); hence supporting the current classification system placement of these disorders.

Abstract
INTRODUCTION This study aimed to establish the association between alexithymia and various factors, mainly somatization, and to determine the predictors of alexithymia in depressed patients. METHODS A total of 90 patients with major depressive disorder who met The Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) diagnostic criteria were administered the Toronto Alexithymia Scale (TAS), Beck Depression Inventory, Symptom Checklist-90 (SCL-90), Somatosensory Amplification Scale, and Symptom Interpretation Questionnaire. The patients were classified into two groups as alexithymic and non-alexithymic with respect to the TAS cut-off points (≥59=alexithymic). Predictors of alexithymia were tested by multiple linear regression analysis. RESULTS Of all patients, 36 (40%) were in the alexithymic group. The percentage of women, depression severity, level of general psychopathology and distress, and somatic symptom reporting (SCL-90), as well as the tendency to somatosensory amplification and three forms of somatic symptom attributions, were significantly higher in alexithymic patients than in non-alexithymic patients. Furthermore, age, depression severity, somatic symptom reporting, and the tendency to attribute physical symptoms to somatic causes were predictors of alexithymia. CONCLUSION The results indicated an intimate association between alexithymia and somatization in depressed patients. Therefore, when evaluating depressed patients with alexithymia, their tendency for somatization should be considered, and alexithymic individuals should be assessed with particular attention, considering that somatization can mask the underlying depressive condition.

Abstract
Interpersonal forms of trauma are among the most commonly reported traumas. These types of traumas are more damaging to well-being than noninterpersonal forms. They have also been strongly associated with somatic symptoms and more general physical health problems. Nevertheless, the results of trauma studies are mixed and suggest that pathways may vary according to the stressors, mediators, and health outcomes investigated. This article presents a systematic qualitative review of published studies that have investigated interpersonal trauma, its association with physical health, and the potential role of intervening psychological variables. A systematic search was made of four psychology and health electronic databases. Of the 863 studies reviewed, 50 were preselected, 11 of which met the inclusion and methodological quality criteria. All but one study had a cross-sectional design. The findings showed that childhood trauma exposure was the most common category of interpersonal trauma addressed in the reviewed studies and that the physical health variables investigated were diverse. The psychological variables most frequently investigated in the studies were posttraumatic stress disorder, depression, dissociation, and substance abuse. Overall, the results suggest that interpersonal trauma exposure is associated with poorer physical health; however, the role of intervening psychological variables remains unclear. The limitations of the reviewed literature are discussed, and methodological recommendations are made for future research.

Abstract
Patients with depression exhibit high rates of alexithymia, representing a major public health concern. We sought to examine relationships between depression severity and alexithymia as assessed by the Toronto Alexithymia Scale (TAS-20) and the TAS-20 subscales of difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and externally oriented thinking (EOT). Potentially relevant studies were obtained independently by two reviewers. Chi-square statistics based on the Q-test and I(2) index assessed statistical heterogeneity between studies. Subgroup analyses were mainly used to explore sources of heterogeneity. Begg׳s test and Duval and Tweedie' trim and fill were used to assess potential publication bias. Altogether, 3572 subjects from 20 study groups across 19 studies were included. Medium relationships were observed between depression and TAS-total score (TAS-TS), DIF, and DDF. There was also a weak relationship between EOT and depression. Subgroup analyses showed a stronger correlation between TAS-TS and depression assessed by self-reported tools than that assessed by the Hamilton Rating Scale for Depression. The heterogeneity significantly decreased only in the subgroup analysis by depression tool. We conclude that alexithymia, as assessed by the TAS-20 and its subscales DIF and DDF, is closely related to depression. These relationships were affected by depression measurement tools.

Abstract
OBJECTIVE This study sought to determine the trauma-related psychiatric comorbidity of somatization disorder among women who applied to an outpatient psychiatric unit of a general hospital in eastern Turkey. METHODS Forty women with somatization disorder and 40 non-clinical controls recruited from the same geographic region participated in the study. Somatization disorder and posttraumatic stress disorder (PTSD) sections of the Structured Clinical Interview for DSM-IV (including its criterion A traumatic events checklist), Dissociative Disorders Interview Schedule, Dissociative Experiences Scale (Taxon), Hamilton Depression Rating Scale, and Childhood Abuse and Neglect Questionnaire were administered to all participants. RESULTS A significant proportion of the women with somatization disorder had the concurrent diagnoses of major depression, PTSD, dissociative disorder, and borderline personality disorder. Women with somatization disorder reported traumatic experiences of childhood and/or adulthood more frequently than the comparison group. A significant proportion of these patients reported possession and/or paranormal experiences. Binary logistic regression analysis demonstrated that current major depression, being married, total number of traumatic events in adulthood, and reports of possession and/or paranormal experiences were independent risk factors for somatization disorder diagnosis. CONCLUSIONS Among women with endemically high exposition to traumatic stress, multiple somatic complaints were in a significant relationship with major depressive disorder and lifelong cumulative traumatization. While accompanying experiences of possession and paranormal phenomena may lead to seeking help by paramedical healers, the challenge of differential diagnosis may also limit effective service to this group of somatizing women with traumatic antecedents and related psychiatric comorbidities.

Abstract
In an undergraduate sample ( N = 214), we examined the construct validity of the Clinician Administered Dissociative States Scales (CADSS; Bremner, Krystal, Putnam, Southwick, Marmar, Charney, et al., 1998) in the context of measures of state and trait dissociation, administered in conjunction with measures of depression, state anxiety, and affect. We found evidence for the convergent and discriminant validity of the dissociation measures in terms of correlations among dissociation measures that exceeded the correlations of the dissociation measures with measures of other constructs. Internal consistencies of the dissociation measures exceeded .80. Multiple regression analyses provided further evidence of construct validity in that variance in dissociation scores was largely accounted for by scores on other dissociation measures. Nevertheless, measures of anxiety, affect, and depression accounted for incremental variance in the prediction of dissociation measures and therefore should be included in a comprehensive model of dissociation. Our results strongly support the construct validity of the measures of dissociation.

Abstract
Understanding which factors predict individual dissociative response during stressful situations is important to clarify the nature of dissociation and the mechanisms associated to its use as a coping strategy. The present study examined (1) whether experiential avoidance (EA), anxiety sensitivity (AS), depressive symptoms, and state anxiety concurrently predicted trait dissociation (TD)-absorption, amnesia, depersonalization, and total TD scores-and laboratory induced dissociation (LID); and (2) whether TD and catastrophizing predicted LID. We also examined whether catastrophizing mediated the relationships between both AS and depressive symptoms and LID. A total of 101 female undergraduate students participated in a cold pressor task, which significantly induced dissociation. Results of hierarchical regression analyses showed that AS at Time 1 (9 months before the experimental session), as well as depressive symptoms and catastrophizing at the time of the experiment (Time 2), predicted LID at Time 2. Depressive symptoms at Time 2 predicted total TD, absorption, and amnesia scores. AS at Time 1 and depressive symptoms at Time 2 predicted depersonalization. AS, depressive symptoms, and catastrophizing seem to facilitate the use of dissociative strategies by healthy individuals, even in response to non-traumatic but discomforting stress.

Abstract
This study examined the levels of posttraumatic stress disorder (PTSD) following asthma attack (post-asthma attack PTSD) and psychiatric co-morbidity among college students. It also investigated the association between these variables and alexithymia. One hundred and six college students participated in the study and completed an on-line survey comprising the Asthma Symptom Checklist, PTSD Checklist, General Health Questionnaire-28 and Toronto Alexithymia Scale. Ninety-one students without asthma and major illness formed the control group. 2 % met the diagnostic criteria for full-PTSD, while 42 and 56 % met the partial and no-PTSD criteria respectively. Compared with the control, the asthma group reported significantly more somatic problems, social dysfunction and depression and was five times more likely to have an elevated risk of developing a general psychiatric disorder. After adjusting age, marital status, asthma experience and symptoms, alexithymia did not predict PTSD, while difficulty identifying feelings predicted psychiatric co-morbidity. Mediational analyses showed that asthma symptoms partially mediated the link between difficulty identifying feelings and psychiatric co-morbidity. People can develop PTSD symptoms and other psychological difficulties following asthma attack. Alexithymia influenced general psychological difficulties independently of PTSD symptoms.

Abstract
INTRODUCTION The current study investigated whether the influence of alexithymia on psychological distress (PD) differed according to the seriousness of complicated grief (CG) and the time since bereavement in the Japanese general population. METHODS 1162 participants between 40 and 79 years of age (effective response rate: 58.8%) completed a cross-sectional anonymous questionnaire regarding the following factors: alexithymia (DD: Difficulty describing feeling, DI: Difficulty identifying feeling, EO: Externally oriented thinking), PD, and CG. To compare the non-bereaved (group 1) with four other groups, which were organized by CG score (high/low) and the time since bereavement (within half/two years postloss); the half year_low/high CG (group 2 and 3) and the two years_low/high CG (group 4 and 5), a simultaneous analysis of the five groups with standard maximum likelihood estimations was performed and hypothesized models were verified. RESULTS The model (RMSEA=0.000, AIC=57.686) showed that the models' constructions for group 1 and 4 were significantly similar. In the other groups, the degree of correlation between alexithymia (especially EO) and psychological distress was significantly different. LIMITATIONS The study is a cross-sectional design and not with a clinical population. CONCLUSIONS Our findings showed that the relationship between alexithymia and psychological distress was significantly same for group 1 and 4. In group 2, EO was less correlated with the other subscales of alexithymia, which suggests that EO is utilized as a coping style for bereavement that, in turn, influences convalescence during the half year following bereavement.

Abstract
Quality of life (QOL) has been defined in many ways, and these definitions usually emphasize happiness and satisfaction with life. Health-related problems are known to cause lower QOL. However, the neural mechanisms underlying individual differences in QOL measured by questionnaire (QOLMQ) in young healthy subjects are unknown. QOL is essential to our well-being, and investigation of the neural mechanisms underlying QOL in uncompromised subjects is obviously of great scientific and social interest. We used voxel-based morphometry to investigate the association between regional gray matter volume (rGMV) and QOLMQ across the brain in healthy young adults (age, 21.4 ± 1.8 years) men (n = 88) and women (n = 68) in humans. We found significant negative relationships between QOLMQ and rGMV in a region in the left rostrolateral prefrontal cortex and regions in the dorsal part of the anterior cingulate gyrus and contingent cingulate regions. These findings show that structural variations in regions associated with processing of negative emotions such as fear and anger as well as those associated with evaluation of internally generated information are associated with QOLMQ. These findings suggest that these processes might be related to QOLMQ in healthy young adults.

Abstract
BACKGROUND The ability to self-report on affective experience is essential to both our everyday communication about emotion and our scientific understanding of it. However, the underlying cognitive and neural mechanisms for how people construct statements even as simple as "I feel bad!" remain unclear. We examined whether the neural architecture underlying the ability to make statements about affective experience is composed of distinct functional systems. METHODS In a novel functional magnetic neuroimaging paradigm, 20 participants were shown images varying in affective intensity; they were required either to attend to and judge the affective response versus to nonaffective aspects of the stimulus and either to categorize their response into a verbal label or report on a scale that did not require verbal labeling. RESULTS We found that the ability to report on affective states involves (at least) three separable systems, one for directing attention to the affective response and making attributions about it that involves the dorsomedial prefrontal cortex, one for categorizing the response into a verbal label or word that involves the ventrolateral prefrontal cortex, and one sensitive to the intensity of the affective response including the ventral anterior insula and amygdala. CONCLUSIONS These results suggest that unified statements about affective experience rely on integrating information from several distinct neural systems. Results are discussed in the context of how disruptions to one or another of these systems may produce unique deficits in the ability to describe affective states and the implications this may hold for clinical populations.

Abstract
This study examined concordance between physiological arousal and subjective distress during a laboratory challenge task. Data were collected during the multisite VA Cooperative Study 334 in the early 1990s examining psychophysiological arousal among combat-exposed Vietnam veterans with (n = 775) and without (n = 369) posttraumatic stress disorder (PTSD). Study participants were presented with 6 standardized neutral scenes and 6 standardized combat scenes. Participants provided a subjective rating of distress after each slide. During the presentation, levels of heart rate (HR) and skin conductance (SC) were recorded. Using linear mixed effects modeling, both HR level and SC level exhibited significant positive associations with subjective distress ratings (pr = .33, p < .001 and pr = .19, p < .001, respectively). Individuals with PTSD demonstrated greater concordance between their distress ratings and SC level during exposure to combat slides than participants without PTSD (pr = .28, p < .001 vs. pr = .18, p < .001). Although a significant association was found between subjective distress and HR reactivity and SC reactivity, these findings were not moderated by PTSD status. The results of these analyses suggest that patients' reports of distress during exposure-based treatments might serve as approximate measures of actual physiological arousal.

Abstract
The aim of this study was to evaluate possible interactions between severity of borderline personality features (BPFs), dissociative experiences, and alexithymia among substance-dependent men while controlling for their current age, depression, and anxiety. Participants were 200 substance-dependent men consecutively admitted to a dependency treatment unit. The Borderline Personality Inventory, the Toronto Alexithymia Scale, the Dissociative Experiences Scale, the Beck Depression Inventory, and the Spielberger State-Trait Anxiety Inventory were administered to all participants. Severity of negative affect, alexithymia, dissociative experiences, and BPF were correlated with each other. Being younger, severity of dissociative experiences, difficulty in identifying feelings, depression, and trait anxiety predicted the severity of BPF in linear regression analysis. These findings suggest that alexithymia and dissociative experiences may be a way of coping with depression and chronic anxiety, but they also seem to be related to the severity of BPF independent of the negative affect and from each other.

Abstract
A number of researchers have argued for the existence of different subtypes of posttraumatic stress disorder (PTSD). In the current paper we present criteria by which to assess these putative subtypes, clarify potential pitfalls of the statistical methods employed to determine them, and propose alternative methods for such determinations. Specifically, three PTSD subtypes are examined: (1) complex PTSD, (2) externalizing/internalizing PTSD, and (3) dissociative/nondissociative PTSD. In addition, three criteria are proposed for subtype evaluation, these are the need for (1) reliability and clarity of definition, (2) distinctions between subtypes either structurally or by mechanism, and (3) clinical meaningfulness. Common statistical evidence for subtyping, such as statistical mean difference and cluster analysis, are presented and evaluated. Finally, more robust statistical methods are suggested for future research on PTSD subtyping.

Abstract
In the present study we surveyed 131 adults seeking psychotherapy and pastoral care in an intensive outpatient psychotherapy program for full-time religious workers. We sought to determine whether dissociation and alexithymia are associated with spiritual well-being. We utilized the Dissociative Experiences Scale-II (DES-II), the Toronto Alexithymia Scale (TAS-20), the Spiritual Well-Being Scale (SWB) as well as the subscales of these instruments in a series of linear multiple regression analyses. DES-II total scores were inversely related to SWB total scores. No association was found between alexithymia and SWB, nor did alexithymia moderate the relationship between dissociation and SWB. Subscale analyses revealed that lower SWB and Existential Well-Being (EWB) were associated with greater nonpathological dissociation (DES-NP), which was unrelated to Religious Well-Being (RWB). By contrast, lower RWB was predicted by higher pathological dissociation (DES-T), which displayed no relationship to SWB or EWB. We conclude with a discussion of some implications of these findings.

Abstract
BACKGROUND The present research investigated whether the relationship between alexithymia and complicated grief was different from the relationship between alexithymia and general depressive symptom according to the seriousness of complicated grief in the Japanese general population. METHODS In the Japanese general population sample, 948 participants between 40 and 79 years old (effective response rate, 48.0%) completed a cross-sectional anonymous questionnaire about alexithymia, depression, and complicated grief. To compare the high risk (n=243) and low risk (n=705) of complicated grief groups, simultaneous analysis of two groups with standard maximum likelihood estimation was performed and six hypothesized models were verified. RESULTS The model (RMSEA=0.047, AIC=71.520) that showed that the path coefficients of the latent variable of alexithymia to the observed variables were equal and that the path coefficient of alexithymia to psychological distress was equal was adopted. The contribution ratios from alexithymia to complicated grief were apparently smaller (2-4%) than those to depression (37-38%). CONCLUSIONS Our findings showed that alexithymia scarcely contributed to complicated grief compared to depression and that the contribution ratio in the high risk group was lower than that in the low risk group. The contribution of the latent variable of psychological distress to complicated grief and depression was lower in the high risk group than in the low risk group. The lack of a correlation between alexithymia and complicated grief might indicate that there are different mechanisms underlying the symptoms of alexithymia and complicated grief.

Abstract
Conditions that impede the regulation of emotional arousal, such as alexithymia and dissociation, may underlie panic attacks. This study aimed to evaluate the relationship between alexithymia and dissociation in patients with panic disorder (PD). We assessed 95 PD outpatients with regard to alexithymia (20-item Toronto Alexithymia Scale), dissociation (Dissociation Experience Scale), and overall psychological distress (Symptom Checklist 90-Revised, Global Severity Index). Regression analyses revealed a positive correlation between alexithymia and dissociation, even when the Global Severity Index was controlled for. A specific link was observed between "difficulty in identifying feelings" and "depersonalization/derealization." Patients who showed the pathological form of dissociation had higher levels of alexithymia, with particular regard to "difficulty in identifying feelings" and, to a smaller extent, "difficulty in describing feelings." These results support a strong relationship between alexithymia and dissociation in patients with PD. Assessing alexithymia and dissociation at the outset of therapy may be helpful for individualized therapy planning.

Genetic influences on alexithymia and their relationship with depressive symptoms. J Psychosom Res 2011; 71:256-63.

Abstract
OBJECTIVE The factors involved in the etiology of alexithymia are still unclear. While a few studies suggested substantial genetic influences on alexithymia, it remains to be determined if these influences are independent of genetic influences on other mental health variables correlated with alexithymia, such as depression. This study is aimed at confirming previous findings of a genetic contribution to alexithymia, examining whether there are genetic or environmental influences common to alexithymia facets, and investigating whether genetic influences on alexithymia are independent of genetic influences on depression. METHODS The 20-item Toronto Alexithymia Scale and a validated measure of depression were administered to a sample of 729 twins (45% males) aged 23-24 years drawn from the population-based Italian Twin Register. Genetic structural equation modeling was performed with the Mx program. RESULTS Genetic factors accounted for 42% of individual differences in alexithymia. Unshared environmental factors explained the remaining proportion of variance. There was a substantial (0.65) genetic correlation between alexithymia and depression. The inclusion of depression as a covariate in the genetic models reduced the heritability estimate for alexithymia to 33%. CONCLUSIONS Despite some limitations, this study corroborates the notion that genetic factors contribute substantially to individual differences in alexithymia, with unshared environmental factors also playing an important role. Also, it suggests a genetic link between alexithymia and depression.

Abstract
OBJECTIVE To identify clinical variables and genetic variations within monoaminergic genes known to be implicated in pain perception that are associated with the occurrence of somatization symptoms in patients with major depression. METHOD Somatization was evaluated using the respective subscale of the Symptom Checklist SCL-90-R. Six monoaminergic genes were identified showing an involvement in pain perception and somatization according to the literature: COMT, HTR2A, SLC6A2, SLC6A4, DRD4, and TPH1. One hundred and eighteen single nucleotide polymorphisms (SNPs) within these genes were genotyped using Illumina BeadChips in a sample of 398 at least moderately to severely depressed in-patients participating in the Munich Antidepressant Response Signature (MARS) project. RESULTS Thirty SNPs exhibit nominally significant associations with somatization. One SNP (rs9534505) located in intron 2 of the HTR2A gene withstood correction for multiple testing. Clinical data provide further evidence for strong impact of somatization on the presentation of depressive symptoms and description of a patient subgroup with unfavorable clinical outcome. CONCLUSION Our results demonstrate the influence of a HTR2A polymorphism on aspects of somatization in major depression, which co-occurs with an unfavorable antidepressant treatment outcome. These results confirm and expand previous findings on somatization as a risk factor for treatment outcome in major depression.

Abstract
OBJECTIVE To examine prospectively the association of psychological distress with the development of the metabolic syndrome (MetS) and the potential influence of demographic characteristics, health behaviors, and inflammation in this association. METHODS A total of 466 (n = 185 males; 281 females) subjects, aged 36 to 56 years, and free of MetS at baseline, participated in a population-based study from 1997 to 1998 and again from 2004 to 2005. Mean observation time was 6.4 years. Various clinical, biochemical, and behavioral factors were measured at baseline, including assessment of psychological distress using the 12-item General Health Questionnaire. The development of MetS was measured at follow-up based on National Cholesterol Education Program criteria. RESULTS Subjects with high psychological distress at baseline (General Health Questionnaire scores, 4-12) were more than twice as likely to develop MetS than those with low psychological distress (odds ratio, 2.18; 95% confidence interval, 1.30-3.64). Adjustments for 1) age, gender, and sociodemographic variables; 2) health behaviors (smoking, alcohol use, and leisure time physical activity); and 3) C-reactive protein in the analysis diminished the odds of developing MetS in the distressed group (odds ratio, 1.87; 95% confidence interval, 1.83 and 1.81, respectively); however, the association remained statistically significant (p = .025-.038). CONCLUSIONS Psychological distress at baseline increases the risk of developing MetS during follow-up. This association remained robust after adjusting for age, gender, sociodemographic variables, baseline health behaviors, and C-reactive protein. These prospective findings are evidence of a significant association between psychological distress and the development of MetS.

Abstract
OBJECTIVE Conversion, dissociation and somatization are historically related in the long established concept of hysteria. Somewhere along the way they were separated due to the Cartesian dualistic view. The aim of the present study was to compare these pathologies and investigate whether symptoms of these pathologies overlap in their clinical appearance in a Portuguese sample. METHOD Twenty-six patients with conversion disorder, 38 with dissociative disorders, 40 with somatization disorder, and a comparison group of 46 patients having other psychiatric disorders answered questions about dissociation (Dissociative Experiences Scale), somatoform dissociation (Somatoform Dissociation Questionnaire), and psychopathological symptoms (Brief Symptom Inventory). RESULTS Dissociative and somatoform symptoms were significantly more frequent in dissociative and conversion disorder than in somatization disorder and controls. There were no significant differences between dissociative and conversion patients. CONCLUSIONS Conversion disorder is closely related to dissociative disorders. These results support the ICD-10 categorization of conversion disorder among dissociative disorders and the hypothesis of analogous psychopathological processes in conversion and dissociative disorders versus somatization disorder.

Abstract
OBJECTIVE Alexithymia is hypothesized to be a stable trait that hinders favourable outcomes of psychotherapy. We tested two hypotheses: i) alexithymia is not stable but changes along with a change in depressive symptoms and ii) pretreatment alexithymia hinders gaining benefits from psychotherapy. METHOD A total of 201 participants (mean age = 54 years, SD = 4.4) with subthreshold depression were treated with cognitive behaviour therapy. Outcome was defined as the change in depressive symptoms from pretreatment to post-treatment and to 1-year follow-up. RESULTS Changes in depressive symptoms were significantly correlated with changes in alexithymia. Baseline alexithymia scores were not correlated with treatment outcome. CONCLUSION Alexithymia is less stable than hypothesized: changes in alexithymia were associated with change in depressive symptoms. Furthermore, alexithymia does not hinder cognitive behaviour therapy outcome.

Abstract
AIM The aim of the present study was to evaluate the relationship between alexithymia and dissociation among men with alcoholism. METHODS Participants were 176 patients consecutively admitted to the inpatient unit of a addiction treatment center. The Toronto Alexithymia Scale, the Symptom Checklist-Revised, the Dissociative Experiences Scale, the Beck Depression Inventory, the Spielberger State-Trait Anxiety Inventory, and the Michigan Alcoholism Screening Test were administered to all participants. RESULTS Fifty-three patients were considered as having alexithymia. The alexithymic group had a significantly higher rate of dissociative taxon members (patients with pathological dissociation; 62.3%) according to Bayesian probability. Trait anxiety, overall psychiatric symptom severity, and pathological dissociation predicted alexithymia on covariance analysis. A multivariate analysis of covariance demonstrated that these predictors were related only to difficulty of identifying feelings, whereas trait anxiety was a significant covariant for difficulty of expressing feelings as well. CONCLUSION Alexithymic phenomena are interrelated with dissociation and chronic anxiety among men with alcoholism. The relevance of this triad for prevention and treatment of alcoholism deserves interest in further research.
