Abusive relationships in families of women with borderline personality disorder, anorexia nervosa and a control group

In a group of intact families, we examined the rates and parameters of verbal, physical, and sexual abuse in 35 women with borderline personality disorder (BPD), 34 women with anorexia nervosa (AN), and 33 women without a clinical history (NC); their experience of multiple abuse and its correlation with their SCL-90-R scores; and their reports of abuse of their siblings. Corroboration of abuse was obtained from some parents in each group. Women with BPD suffered more intrafamilial verbal and physical abuse. Whereas AN and NC women experienced relatively rare single events of extrafamilial sexual abuse at an older age, those with BPD suffered repeated intrafamilial sexual abuse at a younger age and also suffered more multiple abuse. All multiply abused women had more psychopathology. Siblings were reported abused in the same proportions as subjects; many parents of BPDs corroborated their daughters' reports of all three forms of abuse.     

Alexithymia in adolescents with borderline personality disorder

ObjectiveThe aim of this study was to explore the relationship between alexithymia and borderline personality disorder (BPD) in adolescents.MethodsThe study investigated a sample of 59 consulting or inpatient adolescents with a well-established diagnosis of BPD (SIDP-IV) and a control sample of healthy adolescents individually matched by gender, age and socio-economic status. Alexithymia, depression and trait-anxiety were rated using the Twenty-item Toronto Alexithymia Scale (TAS-20), the Beck Depression Inventory (BDI-II) and the trait-anxiety subscale from the State-Trait Anxiety Inventory (STAI-T), respectively. A confirmatory factorial analysis (CFA) was performed to test the fit of the three-factor structure of the TAS-20 in the adolescent sample (N = 140). BPD and control groups were compared on alexithymic scores using ANCOVA analyses controlling for the potential confounding effects of depression and anxiety.ResultsThe ratio of the chi-square to its degrees of freedom, the goodness-of-fit index, the adjusted goodness-of-fit index and Steiger's root-mean-square error of approximation had satisfactory values of 1.54; 0.87; 0.83 and 0.058, respectively. The two ANCOVA demonstrated no significant difference for TAS-20 scores. BPD subjects were more alexithymic than healthy subjects but this difference was mainly explained by the levels of depression or anxiety.LimitationsSince BPD subjects have high comorbidity with depression or anxiety, longitudinal studies examining the absolute and relative stability of TAS-20 scores are necessary to determine whether alexithymia constitutes a state or a trait in BPD.ConclusionsBPD adolescents are characterized by alexithymia, probably of a secondary or state-dependent nature.     

Alexithymia,temperament and character as predictors of psychopathology in patients with major depression

The study investigated the capacity of alexithymic personality features, in combination with temperament and character traits, age and gender, to predict psychopathological symptoms in patients with major depression. Consecutive patients (n = 339) were investigated using the Toronto Alexithymia Scale-20 (TAS-20), the Temperament and Character Inventory (TCI), the Symptom Checklist-90-R (SCL-90-R), and the Hamilton Depression and Anxiety Rating Scales (HDRS, HARS). The amount of variance in SCL-90-R subscales and Hamilton scales predicted by TAS-20, TCI, age and gender was calculated by linear regression analyses. The ‘difficulties identifying feeling’ facet of alexithymia appeared to be a significant predictor of all dimensions of psychopathology. Among TCI scales harm avoidance was the strongest predictor for somatization, phobic anxiety, and anxiety (SCL-90-R, HARS); low self-directedness was the strongest predictor for obsessionality, depression (SCL-90-R, HDRS), interpersonal sensitivity and psychoticism; and low cooperativeness was the strongest predictor for hostility and paranoia. In conclusion, many psychopathological symptoms in major depression are associated with difficulties in the identification of emotions. Relative to alexithymia, Cloninger's psychobiological model of personality could predict psychopathological symptoms in a distinct and meaningful manner. The TAS-20 and the TCI are useful questionnaires for a better understanding of the relationship between psychopathology and personality in major depression.     

Validity of the BVAQ: a study in eating disorder patients and controls

Alexithymia core features are the difficulties in identifying and describing feelings; the difficulties in distinguishing feelings from the bodily sensations of emotional arousal; an impaired symbolization, as evidenced by a paucity of fantasies and other imaginative activity; and a tendency to focus on external events rather than inner experience. Several measures of alexithymia have been developed, including interviewer-rated questionnaires and self-report questionnaires. Among the self-report questionnaires, the 20-item Toronto Alexithymia scale (TAS-20) is the most commonly used, but it fails to measure all the core features of alexithymia. A recently developed instrument, the Bermond-Vorst Alexithymia Questionnaire (BVAQ), allows the measurement of the alexithymia core features, as well as an additional one. It appeared to present good psychometric properties, notably the abbreviated BVAQ-form B. The results of recent studies comparing the psychometric properties of the TAS-20 and the BVAQ have recommended the BVAQ over the TAS-20. However, this questionnaire needed further validation. OBJECTIVES: Thus, the aim of the present study was to determine the convergent, discriminant and concurrent validity of the Bermond-Vorst Alexithymia Questionnaire -- form B (BVAQ-B) in a clinical sample of 59 eating disorder patients, as well as in 191 controls. The TAS-20 constituted the gold standard for the assessment of the BVAQ-B' convergent validity. To compare the concurrent validity of the BVAQ-B and the TAS-20, participants also completed several self-reports investigating different dimensions of emotion regulation capacities: the 13-item Beck Depression Inventory (BDI), the Spielberger State and Trait Anxiety Inventory (STAI-form Y), as well as the Chapman and Chapman Physical and Social Anhedonia Scales (PAS and SAS). One way analyses of variance were used for mean scores comparisons. Convergent validity was determined using Pearson coefficients of correlation. RESULTS: Results of the analyses suggested the BVAQ-B has a satisfying convergent and discriminant validity. This was observed in both the clinical and control samples. Moreover, the comparison of the convergent validity of the BVAQ-B and the TAS-20 revealed several differences between these two alexithymia self-report questionnaires. The BVAQ-B appeared less sensitive to the subjective emotional state of the participants than the TAS-20. Whereas it was argued the TAS-20 overlaps with other emotional state scores, the BVAQ-B would allow to measure alexithymia more specifically. In addition, the present results allowed to further determine the relations between alexithymia and other dimensions of emotion regulation capacities. The analyses confirmed that alexithymia is linked to other emotion regulation dimensions such as depression and anxiety. Moreover, alexithymia was associated with physical and social anhedonia, two dimensions that received less interest in the alexithymia literature to date. This study also showed that control and clinical sample have different emotion regulation capacities. Eating disorder patients were not only more alexithymic and more depressed, but also more anxious and more anhedonic than the controls. Finally, this study revealed that alexithymia differs whether the alexithymic individuals are patients or controls. Healthy alexithymic individuals (ie, individuals categorized as alexithymic in the control group) seemed characterised by a selective deficit of emotional cognition, with sparing of emotional experience (Bermond's type II alexithymia). Alexithymics individuals of the eating -disorder group seemed particularly unabled to experience affect. This pattern could correspond to Bermond's type I alexithymia, which is characterised by the absence of emotional experience and, consequently, by the absence of the cognition accompanying the emotion. In summary, results of the present study add to the literature debating on whether alexithymia is similar in different types of population.     

Effects of inpatient psychotherapy on the stability of alexithymia characteristics

Background

Although alexithymia is associated with several psychiatric disorders, there has been little research into the effects of psychodynamic psychotherapies on this condition. Here, the influence of inpatient multimodal psychodynamic psychotherapy on alexithymia and symptom load was evaluated in a large sample of patients.

Methods

Alexithymia [measured with the Toronto Alexithymia Scale (TAS)-26] and psychological stress and depression [measured with the Symptom Checklist 90 Revised (SCL-90-R)] were evaluated at admission and after inpatient multimodal psychotherapy in patients with various psychosomatic and psychiatric disorders admitted to this unit between 2002 and 2005. Patients undergoing both short-term (up to 4 weeks) and long-term treatment (8-12 weeks) were studied. Analyses of covariance were used to analyse the data on depression (SCL-90-R) and psychological stress (SCL-90-R), and correlations between admission and discharge scores for the TAS-26 were computed to evaluate mean and relative stability of alexithymia.

Results

Data on 397 of the 568 patients admitted were analysed. Psychological stress and depression (SCL-90-R) decreased significantly during the study across all diagnostic groups. The TAS-26 total score also decreased significantly, showing that there was no mean stability of alexithymic characteristics. However, the significance of decrease was lost when psychological stress and depression were controlled for. Highly significant correlations between TAS-26 sores before and after treatment reflected high relative stability of alexithymia.

Conclusions

During inpatient multimodal psychodynamic treatment, the symptom load and alexithymia in our patients decreased. The high relative stability of alexithymia shown supports the view that alexithymia is a relative stable personality trait.     

Pre-morbid alexithymia in panic disorder: A cohort study

Whether alexithymia is a personality trait which increases the risk of Panic Disorder (PD) is still debated. In this prospective study, alexithymic levels were evaluated before, during and after an anxious episode. Therefore, the alexithymic levels, the presence of PD and the severity of anxious-depressive symptoms were evaluated, at intervals of about 1 month, in pregnant women, attending the Centers for Prenatal Care, using the Toronto Alexithymia Scale (TAS-20), the Primary Care Evaluation of Mental Disorders and the Hospital Anxiety and Depression Scale (HADS). Twenty-one women affected by PD and 256 healthy women (controls) were included in the study. Women who developed PD, compared to controls, showed similar TAS-20 and HADS scores during the pre-morbid phase, a significant increase of them during PD and a significant decrease after symptoms improvement, whereas no change was observed in controls. Our data suggest that in pregnant women alexithymia does not represent a personality trait that increases the risk of developing PD, and they support the hypothesis that alexithymia is a state dependent phenomenon in PD pregnant women.     

Alexithymia and temperament and character model of personality in patients with major depressive disorder

Alexithymia is thought to be a stable personality trait and a predisposing risk factor for depression. In this study, we aimed to identify the prevalence of alexithymia in a depressed and nondepressed sample and examined the relationship between Cloninger's psychobiological model of personality with alexithymia. The Turkish version of the 20-item Toronto Alexithymia Scale (TAS-20), the Turkish version of the Temperament and Character Inventory, and the 21-item Beck Depression Inventory (BDI) were administered to 81 depressed patients and 51 controls. The mean age of the groups was 30.5 ± 7.7 and 32.75 ± 8.73, respectively. Depression severity was evaluated with the BDI. In the depressed group, 33.3% were alexithymic, and alexithymic subjects had significantly higher BDI scores. Depressed individuals were significantly more alexithymic than the controls on the total and all the 3 subscales of TAS-20. The TAS-20 total score was negatively correlated with the temperament dimension of Reward Dependence (RD) and the character dimension of Self-Directedness (SD). In the TAS-20 subscale, difficulties in identifying feelings was positively correlated with Self-Transcendence and negatively correlated with SD. The difficulties in expressing feelings subscale was negatively correlated with RD and SD. In the depressed patient group, the temperament dimension of RD was significantly lower in the alexithymic group. The rate of alexithymia is found high among this sample of Turkish depressed patients, and the results suggested a strong connection between alexithymia and depression. Alexithymia is explained by specific dimensions and subscale within Cloninger's psychobiological model of personality in this sample of depressed Turkish patients.     

Alexithymia,Verbal Ability and Emotion Recognition

Although previous studies seem to indicate that alexithymic individuals have a deficit in their ability to recognize emotional stimuli, none had studied the relationship between alexithymia and verbal and non verbal abilities and their possible role in emotion recognition. The aim of the present study is to further investigate the relationship between alexithymia and emotion recognition ability. In particular we studied whether this relationship is mediated by verbal ability. Thirty-five students were selected from a group of 91 University students previously screened for alexithymia (Toronto Alexithymia Scale; TAS-20). Participants were shown black and white slides depicting facial expression of the following emotions: anger, sadness, disgust, surprise, happiness and fear. Compared to low alexithymic participants, and, more importantly, taking verbal IQ into account, high alexithymic and low alexithymic participants did not differ in emotion recognition.     

The TAS-20 more likely measures negative affects rather than alexithymia itself in patients with major depression,panic disorder,eating disorders and substance use disorders

Background

This study evaluates whether the difference in Toronto Alexithymia Scale-20 item (TAS-20) between patients with major depression (MD), panic disorder (PD), eating disorders (ED), and substance use disorders (SUD) and healthy controls persisted after controlling for the severity of anxiety and depression.

Methods

Thirty-eight patients with MD, 58 with PD, 52 with ED, and 30 with SUD and 78 healthy controls (C) completed the TAS-20, the Hamilton Rating Scale for Anxiety (Ham-A), the Hamilton Rating Scale for Depression (Ham-D).

Results

The differences in TAS-20 scores observed between patient groups, regardless of the type of their disorders, and controls disappeared after controlling for the effect of anxiety and depression severity. In contrast, the differences in severity of anxiety and depression between patients and controls were still present, after excluding the effect of alexithymic levels.

Conclusions

Our data suggest that alexithymic levels, as measured by the TAS-20, are modulated by the severity of symptoms, supporting the view that alexithymia can represent a state phenomenon in patients with MD, PD, ED and SUD, because the TAS-20 seems overly sensitive to a general distress syndrome, and it is more likely to measure negative affects rather than alexithymia itself.     

The Relationship between Alexithymia and General Symptoms of Patients with Depressive Disorders

Objective

Depression has been associated with alexithymic features. However, few studies have investigated the differences in the general symptoms of patients with depressive disorders according to the presence of alexithymia. Thus, the aim of this study was to evaluate the relationship between alexithymia and symptoms experienced by patients with clinically diagnosed depressive disorders.

Methods

A chart review of patients who were evaluated using the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20) and Symptom Checklist 90-Revised (SCL-90-R) at the same time between the years 2003 and 2007 was conducted. A total of 104 patients with depressive disorders were included and divided into two groups: alexithymia (n=52) and non-alexithymia (n=52). A direct comparison between the two groups was carried out. Regression analysis was also carried out for the TAS-20 total and subset scores in order to model the relationship between alexithymia and symptoms.

Results

The presence of alexithymia was confirmed in 50% of the patients with depressive disorders, and the symptoms of depressive patients with alexithymia were more severe than those of their non-alexithymic counterparts on all 9 symptom domains of the SCL-90-R. Furthermore, regression analysis revealed that the presence of alexithymia was positively associated with depression, phobic anxiety, and psychoticism but inversely associated with anxiety.

Conclusion

These results suggest that the clinical features of depression are partially dependent on the presence of alexithymia. Alexithymic patients with depressive disorders are likely to show more severe depressive, psychotic, and phobic symptoms. In other words, clinicians should suspect the presence of alexithymic tendencies if these symptoms coexist in patients with depressive disorders and address their difficulties in effective communication.

Alexithymia in anorexia nervosa: a controlled study using the 20-item Toronto Alexithymia Scale

The 20-item Toronto Alexithymia Scale (TAS) was completed at the age of 22 years by individuals who had previously suffered from anorexia nervosa (AN), and also by members of a comparison group. The AN and comparison groups had been recruited from community samples. Overall, the TAS scores did not clearly discriminate between the two groups. However, the AN group was significantly more often represented among subjects with the highest TAS scores. A subgroup with empathy disorder tended to have particularly high scores. It is concluded that alexithymia, as defined using the TAS-20, is found only in a subgroup of individuals with AN, and possibly more often in those who are also clinically diagnosed as suffering from empathy disorder. The TAS-20 is not suitable for screening of AN in the general population.     

Alexithymia in the German general population

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

The Feeling of Me Feeling for You: Interoception,Alexithymia and Empathy in Autism

Following recent evidence for a link between interoception, emotion and empathy, we investigated relationships between these factors in autism spectrum disorder (ASD). 26 adults with ASD and 26 healthy participants completed tasks measuring interoception, alexithymia and empathy. ASD participants with alexithymia demonstrated lower cognitive and affective empathy than ASD participants without alexithymia. ASD participants showed reduced interoceptive sensitivity (IS), and also reduced interoceptive awareness (IA). IA was correlated with empathy and alexithymia, but IS was related to neither. Alexithymia fulfilled a mediating role between IA and empathy. Our findings are suggestive of an alexithymic subgroup in ASD, with distinct interoceptive processing abilities, and have implications for diagnosis and interventions.     

Does alexithymia differentiate between patients with nonepileptic seizures, patients with epilepsy, and nonpatient controls?

Considering the evidence of an association between alexithymia and somatization, this study aimed to discover whether alexithymia could distinguish patients with psychogenic nonepileptic seizures (NES) from those with epilepsy (ES) and nonpatient controls (C). Toronto Alexithymia Scale (TAS-20) scores were obtained from 21 matched participants from each of these groups, together with measures of anxiety and depression. Overall TAS-20 scores did not differentiate the three groups after controlling for anxiety and depression, but scores on certain subscales of the TAS-20 differed significantly between the patient groups and the controls. Although alexithymia could not discriminate individuals with NES from those with organic manifestations, whether the etiology of alexithymia may differ according to patient group was discussed. Given that 90.5% of NES patients were identified as alexithymic, treatment approaches used for individuals with alexithymia may be usefully applied to those with NES.     

Prevalence of alexithymia and its association with sociodemographic variables in the general population of Finland

The prevalence of alexithymia and its association with sociodemographic variables were studied in a sample of 1285 subjects representing the general population of Finland. Alexithymia was measured with the 20-item Toronto Alexithymia Scale (TAS-20). Alexithymia was normally distributed in the population in both genders, confirming that it is a personality dimension. The prevalence of alexithymia was 13%. Men were alexithymic almost twice (17%) as often as women (10%). Multivariate analysis showed that alexithymia was associated with male gender, advanced age, low educational level, and low socioeconomic status. As to the three factors of the TAS-20, men scored higher in factors 2 (difficulty in describing feelings) and 3 (externally oriented thinking). but there was no gender difference in factor 1 (difficulty in identifying feelings). Comparative population studies in other countries are needed to find out whether there are any differences in the prevalence of alexithymia between cultures.     

The prevalence of alexithymia and its relationship with Youth Self-Report problem scales among Finnish adolescents

This study investigated the relationship between alexithymia, depressive symptoms, and Youth Self-Report (YSR) self-image profiles among 13 to 18-year-old adolescents (n = 7087) attending school in Kuopio, Finland. The final sample consisted of 3936 adolescents (1801 boys, 2135 girls) who completed structured self-rating questionnaires (Toronto Alexithymia Scale [TAS] 20, Beck Depression Inventory [BDI], and YSR) during class periods at school. The overall prevalence of alexithymia was 7.3%. However, girls in all age groups were more frequently alexithymic than boys. Regardless of sex, alexithymic youths reported more depressive symptoms as well as internalizing and externalizing problems than the others. A YSR total score of more than 70 was recorded among 33.4% of alexithymic compared with 3.7% of nonalexithymic adolescents. The TAS-20 correlated significantly with the BDI score, YSR total score, and with internalizing problems. This study revealed alexithymia among adolescents to be associated with various complications such as depressive symptoms, high scores in YSR problem scales, and difficulties in social relationships. Our findings indicate that these adolescents are at high risk of mental disorders and require treatment interventions.     

Somatization and alexithymia in young adult Finnish population

BACKGROUND: We assessed alexithymia and alexithymic features among young adult subjects with and without somatization symptoms in an epidemiological setting with a sample of young adults. METHODS: The sample consisted of urban 31-year-old subjects (N=1002). Data on somatization were gathered from a review of all public health outpatient records. Subjects with four or more somatization symptoms according to the DSM-III-R criteria were considered somatizers. The 20-item version of the Toronto Alexithymia Scale (TAS-20) was used to measure alexithymia. Subjects with a total TAS score over 60 were considered as being alexithymic, and those with a score under 52 were considered nonalexithymic. Subjects with a total TAS score from 52 to 60 were considered as having alexithymic features. RESULTS: The prevalence of alexithymia was 6.0% among somatizers and 4.8% among subjects without somatization symptoms, and the prevalence of alexithymic features was 7.5% and 12.6%, respectively. CONCLUSIONS: No association was found between alexithymia and somatization in young adult general population. The earlier theory of the association between alexithymia and somatization may be questionable.     

Epidemiology of alexithymia among adolescents

OBJECTIVE: In recent years, the occurrence of alexithymia among the general population has been ascertained in a handful of studies. There are no data concerning the epidemiology of alexithymia among teenagers in the general population. We studied the prevalence of alexithymia among a representative sample of 15-16-year olds. METHODS: This study forms part of the Northern Finland Birth Cohort 1986 Study. The original material consisted of all live-born children (N=9432) in the provinces of Lapland and Oulu in Finland, with an expected delivery date between July 1, 1985, and June 30, 1986. In 2001, when the subjects were 15-16 years old, a comprehensive follow-up survey was conducted. The 20-item version of the Toronto Alexithymia Scale (TAS-20) was the measure of alexithymia. Six thousand subjects filled in the TAS-20 correctly. Subjects having a TAS-20 score over 60 were considered to be alexithymic. RESULTS: Of the girls, 10%, and of the boys, 7% were alexithymic. On the other hand, when the alexithymia (TAS-20) score was analysed as a continuous variable, boys had a higher mean value than girls. Mother's low education, broken childhood home, and living in a rural area were associated with high alexithymia score. CONCLUSIONS: The rate of alexithymia among 15-16-year olds was similar to that among adults but with a less obvious gender difference than in an adult population. The association of alexithymia with disadvantageous living conditions in childhood resembles, in a way, its association with poor social situation in studies on working-age subjects.     

The association of interoceptive awareness and alexithymia with neurotransmitter concentrations in insula and anterior cingulate

Alexithymia and increased interoceptive awareness have been associated with affective disorders as well as with altered insula and anterior cingulate cortex (ACC) function. Brain imaging studies have demonstrated an association between neurotransmitter function and affective disorders as well as personality traits. Here, we first examined the relationship between alexithymic facets as assessed with the Toronto Alexithymia Scale (TAS-20) and interoceptive awareness (assessed with the Body Perception Questionnaire) in 18 healthy subjects. Second, we investigated their association with glutamate and gamma-aminobutyric acid (GABA) concentrations in the left insula and the ACC using 3-Tesla proton magnetic resonance spectroscopy. Behaviorally, we found a close association between alexithymia and interoceptive awareness. Furthermore, glutamate levels in the left insula were positively associated with both alexithymia and awareness of autonomic nervous system reactivity, while GABA concentrations in ACC were selectively associated with alexithymia. Although preliminary, our results suggest that increased glutamate-mediated excitatory transmission—related to enhanced insula activity—reflects increased interoceptive awareness in alexithymia. Suppression of the unspecific emotional arousal evoked by increased awareness of bodily responses in alexithymics might thus be reflected in decreased neuronal activity mediated by increased GABA concentration in ACC.
