A confirmatory factor analysis of the Toronto Alexithymia Scale (TAS-20) in an alcohol-dependent sample

Alexithymia and binge eating: Maladaptive emotion regulation strategy or deficient interoception?

Alexithymia has been linked to various excessive behaviors as a likely risk factor, including binge eating. Such relationships are often attributed to deficient emotional self-regulation in alexithymia, ostensibly leading to the use of maladaptive, externalized behaviors as strategies for coping with distress. An alternative view is that alexithymia reflects a fundamental deficit of interoceptive awareness that, in the case of binge eating, would suggest that internal satiety cues are poorly recognized, promoting overconsumption. The present study assessed the relationship between alexithymia and binge eating in the context of these competing hypotheses. A large online sample of young adults (n = 532) completed validated measures of alexithymia, emotion regulation, interoception, binge eating, emotional eating motivation, and sensitivity to reward and punishment. Correlations were as expected except for interoception, which showed minimal association with alexithymia or binge eating. In a hierarchical regression controlling for age, gender, education level and student status as covariates, binge eating was predicted by emotional eating motivation, emotion regulation (a negative predictor), alexithymia, and reward sensitivity, with the final model explaining 53% of variance in binge eating. Bootstrapped path analyses controlling for all other variables indicated that the relationship between alexithymia and binge eating was mediated by deficient emotion regulation but not deficient interoception, and that the relationships of both alexithymia and emotion regulation with binge eating were mediated by emotional eating motivation. Results are consistent with the notion that the association of alexithymia with binge eating reflects deficient emotion regulation in alexithymia, which can lead to adoption of maladaptive, externalized behaviors such as binge eating for coping with distress.

Couple's Satisfaction among Lebanese adults: validation of the Toronto Alexithymia Scale and Couple Satisfaction Index-4 scales, association with attachment styles and mediating role of alexithymia

Background

Lebanon is passing through an economic crisis leading to a decreased monthly income within a couple and more couple’s dissatisfaction. Furthermore, many studies postulate that the different types of attachment styles affect the romantic relationship experienced between adults. The main objectives of our study were to (1) validate the Toronto Alexithymia Scale (TAS) and Couple Satisfaction Index-4 (CSI-4) scales, and (2) assess the association between attachment styles and couple satisfaction and evaluate the mediating role of alexithymia in these associations.

Methods

This cross-sectional study involved 445 Lebanese participants (April–May 2021). A confirmatory factor analysis (CFA) was carried out using SPSS AMOS v.24 on the couple satisfaction index and Toronto alexithymia scales’ items. A linear regression was conducted, taking the couple satisfaction index as the dependent variable.

Results

The CFA results of the CSI-4 scale indicated an excellent fit (χ²/df = 3.845/2 = 1.92, TLI = 0.992, RMSEA = 0.046 [95% CI 0.001–0.115] (pclose = 0.436) and CFI = 0.998). The CFA of the TAS indicated a good/acceptable fit (χ²/df = 422.31/132 = 3.2, TLI = 0.89, RMSEA = 0.07 [95% CI 0.063–0.078] (pclose < 0.001) and CFI = 0.91) (items 4 and 8 were removed due to low factor loading (< 0.4)). Being married and higher secure attachment style were significantly associated with more couple satisfaction, whereas older age, higher household crowding index, more alexithymia and mode depression were significantly associated with less couple satisfaction. In addition, alexithymia mediated the association between secure attachment style and couple satisfaction, between preoccupied attachment style and couple satisfaction and between dismissing attachment style and couple satisfaction.

Conclusion

Couple’s satisfaction is positively associated with secure attachment style. In addition, alexithymia plays a mediating role between couple’s satisfaction and attachment styles. Upcoming studies should determine if other mental illnesses play a mediating role between attachment style and couple satisfaction.

Correlates of emotional intelligence among Lebanese adults: the role of depression, anxiety, suicidal ideation, alcohol use disorder, alexithymia and work fatigue

BACKGROUND

Relationship between emotional intelligence and emotional variables such as stress, depression, anxiety and mental health has been well documented in child and adult samples. New insights into the association between emotional intelligence and different components of mental health in one study (cognitive, emotional and behavioral dimensions) can help patients, therapists, relatives, and friends to understand, explain, and cope with symptoms. There have been no studies assessing the association between the emotional intelligence (EI) with various factors in Lebanon. This study principal aim was to evaluate how EI is related to mental health issues: social anxiety, depression, alcohol use disorders (AUD), work fatigue, stress and alexithymia in Lebanon.

METHODS

789 participants were enrolled in a cross-sectional study between November 2017 and March 2018. A cluster analysis was used to evaluate participants' profiles with the help of emotional intelligence subscales, to separate the Lebanese population into equal limited units with different characteristics using the K-mean technique.

RESULTS

Three clusters were computed dividing participants into low EI (cluster 1; 24.5%), moderate EI (cluster 2; 43.7%) and high EI (cluster 3; 31.7%) respectively. Fitting into the cluster 1 (low EI) was significantly associated with higher AUD, alexithymia, anxiety, depression, perceived stress, social phobia, emotional, mental and physical work fatigue, suicidal ideation compared to cluster 3 (high EI). Fitting into the cluster 2 (moderate EI) was significantly correlated with higher AUD, depression, alexithymia, anxiety, perceived stress, social phobia, mental work fatigue and suicidal ideation compared to cluster 3 (high EI).

CONCLUSION

This study results suggest that emotional intelligence is related to different variables, warranting interventions to limit/decrease alcohol abuse and mental/psychological illnesses as much possible.

Impact of the interaction between alexithymia and the adult attachment styles in participants with alcohol use disorder

The current study aims to investigate the effect of the interaction between adult attachment styles and alexithymia among participants with alcohol use disorder (AUD). This study is cross-sectional, conducted between November 2017 and March 2018, which enrolled 789 community-dwelling participants. The interaction between alexithymia and secure relationship tended to significance (p = 0.057). Higher interaction between alexithymia and a fearful relationship style (β = 0.04) were significantly associated with higher AUD. The interaction model revealed the importance of stratifying the results according to presence/absence of alexithymia. Being a female and having a secure relationship style were significantly associated with lower AUD in both groups. Being divorced was significantly associated with higher AUD in both groups. Increasing age (β = -1.48), secondary (β = -4.65), and university level of education (β = -6.46) were significantly associated with lower AUD in the non-alexithymic group. Intermediate monthly income (β = 2.69) and being widowed (β = 8.24) were significantly associated with higher AUD in the non-alexithymic group. High monthly income (β = 3.46) was significantly associated with higher AUD in the alexithymic group. The results of this study showed that the consideration of the combination between attachment styles and alexithymia is of significance in the diagnosis and therapy of alcohol use disorders.

The associations between alexithymia and both non-suicidal self-injury and risky drinking: A systematic review and meta-analysis

BACKGROUND

Nonsuicidal self-injury (NSSI; direct harm to the body without suicidal intent) and risky drinking are two behaviours that serve emotion regulatory functions. When underlying emotional problems are untreated, individuals may shift between NSSI and risky drinking. Both behaviours are associated with alexithymia, difficulties identifying and describing emotions and retaining an externally orientated thinking style. However, it is unknown to what extent the associations are similar and under what circumstances (e.g. sex, age) they may differ.

METHOD

To compare both associations we conducted an extensive review using several databases. Overall, 20 NSSI-related articles and 33 risky drinking-related articles met the inclusion criteria.

RESULTS

A meta-analysis revealed significant positive associations between total alexithymia scores, difficulties identifying feelings, difficulties describing feelings and both NSSI and risky drinking. However, these associations appear stronger for NSSI. Further, externally orientated thinking was associated with risky drinking but not NSSI. Age had opposing moderating effects on the relationships, with the association between alexithymia and NSSI being stronger in younger samples and the association between alexithymia and risky drinking being stronger in older samples. Further, the association between alexithymia and NSSI was stronger for female only samples compared to male only samples.

LIMITATIONS

The review was limited to English articles. High levels of heterogeneity were observed. The majority of the studies included were cross-sectional.

CONCLUSION

These results imply that NSSI and risky drinking may have both shared and distinguishable correlates. Alexithymia can be targeted in treatment to potentially reduce the likelihood of individuals shifting between behaviours to regulate their emotions.

Factors associated with alexithymia among the Lebanese population: results of a cross-sectional study

Background

To our knowledge, no research project on alexithymia has been conducted in Lebanon. The objective of this study was to assess risk factors associated with alexithymia in a representative sample of the Lebanese population.

Methods

This is a cross-sectional study, conducted between November 2017 and March 2018, which enrolled 789 participants from al districts of Lebanon. The Toronto Alexithymia Scale (TAS-20) was used to measure alexithymia, the Alcohol Use Disorders Identification Test to assess alcohol use, drinking patterns, and alcohol-related issues, the Rosenberg self-esteem scale to evaluate self-worth, the Hamilton depression rating scale and Hamilton Anxiety Scale to screen for depression and anxiety respectively, the Three-Dimensional Work Fatigue Inventory to measure physical, mental and emotional work fatigue respectively, the Columbia–Suicide Severity Rating Scale to evaluate suicidal ideation and behavior, the Perceived Stress Scale to measure stress, the Liebowitz Social Anxiety Scale to help identify a social anxiety disorder and the Quick Emotional Intelligence Self-Assessment to measure emotional intelligence.

Results

The results showed that 395 (50.4%) were not alexithymic, 226 (28.8%) were possible alexithymic, whereas 163 (20.8%) were alexithymic according to established clinical cutoffs. Stress (Beta = 0.456), emotional exhaustion (Beta = 0.249), the AUDIT score (Beta = 0.225) and anxiety (Beta = 0.096) were associated with higher alexithymia, whereas low emotional work fatigue (Beta = −0.114) and being married (Beta = −1.933) were associated with lower alexithymia.

People in distress (Beta = 7.33) was associated with higher alexithymia scores, whereas people with high wellbeing (Beta = −2.18), an intermediate (Beta = −2.90) and a high (Beta = −2.71) family monthly income were associated with lower alexithymia compared to a low one.

Conclusion

Alexithymia appears to be influenced by many factors, including stress, anxiety, and burnout. To reduce its prevalence, it is important that health professionals educate the public about these factors. Further studies on a larger scale are needed to confirm our findings.

Alexithymia and problematic alcohol use: A critical update

There has been a substantial growth in empirical research aimed at examining the co-occurrence of alexithymia and problematic alcohol use and alcohol use disorder (AUD) since Thorberg, Young, Sullivan, and Lyvers (2009) original review article. The objective of the present paper is therefore to provide a critical update review of research on alexithymia and problematic alcohol use published since 2009. A systematic search was conducted through PsychINFO, Medline, and ProQuest databases to obtain relevant literature published between 2009 and 2016. Studies that involved measures of alexithymia and problematic alcohol use among clinical and non-clinical samples were included. Prevalence rates of alexithymia among Alcohol Dependent (AD) samples were identified between 30 and 49%, and were therefore much lower than originally reported. The findings of this update review highlight an indirect relationship between alexithymia and alcohol problem severity that is mediated by a number of psychological drinking constructs (e.g., alcohol expectancy, drinking motives, craving and alcohol related intrusive thoughts) and psychological risk factors for the development of alcohol related problems (e.g., mood and emotion dysregulation, attachment, trauma, and cognitive function). In addition, this review provides reasonable evidence to support alexithymia as an independent risk factor for alcohol related problems among clinical samples only. In conclusion, alexithymia is a multifaceted construct that has a complex relationship with various risk factors and psychological drinking constructs. The growing body of research highlights the demand for understanding the interrelationships between alexithymia, psychosocial risk factors, and problematic alcohol use in order to tailor and target therapeutic interventions.

The association between depression and craving in alcohol dependency is moderated by gender and by alexithymia factors

Alexithymia is a multifaceted personality trait that involves difficulties in identifying and describing feelings to others, a poor fantasy life and an externally oriented cognitive style. Alexithymia has been described as a vulnerability factor for mental and physical diseases. We investigated in a group of 158 alcohol-dependent patients (103 men, 55 women) the association between depression and craving for alcohol when these patients were starting a detoxification program, and the moderating impact of gender and alexithymia on this relation. We first found an interaction between depression and gender in the prediction of craving in the sense that only for women an increase in depressive mood was related to an increase in total craving. When examining gender separately, we found that alexithymia factors acted as moderators. For women, the link between depression and craving was strengthened for the ones scoring higher on "difficulties describing feelings". But for men, the link between depression and craving was reduced for the ones scoring higher on "externally-oriented thinking". These findings suggest that in some cases that need to be identified more systematically in the future, the "externally-oriented thinking" alexithymia factor can exert - at least in the short term - some protective effects.

Disease control in patients with asthma is associated with alexithymia but not with depression or anxiety

This observational cohort study investigated the relationship between alexithymia, coping strategies, anxiety, depression, pulmonary function, and disease control in bronchial asthma (BA) patients who attended a tertiary care center between December 2010 and November 2011. Participants (N = 117) were administered self-report scales measuring anxiety, depression, alexithymia, and coping strategies. Pulmonary function expressed as forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), forced expiratory flow rate over the middle 50% of the FVC (FEF25-75) as% predicted and FEV1/FVC as%, fractional exhaled nitric oxide (FeNO) in ppb and the Asthma Control Test (ACT) were recorded. A hierarchical cluster analysis revealed two clusters of patients with different FEV1 values (p < .001) and alexithymia scores (p < .001). The cluster with lower FEV1 and higher alexithymia used more maladaptive coping strategies (p < .05), and had lower ACT scores (p < .05). Alexithymia was significantly associated with the severity of depression and anxiety symptoms (p < .001 for each comparison). In BA patients, alexithymia was associated with worse pulmonary function and disease control and a more frequent use of maladaptive coping strategies. These results support a multidimensional approach to asthmatic patients, including psychoeducational and behavioral interventions aimed at reducing maladaptive coping strategies.

Risky cannabis use is associated with alexithymia, frontal lobe dysfunction, and impulsivity in young adult cannabis users

Risky or problematic alcohol use by young adults has been found to be associated with factors such as alexithymia, frontal lobe dysfunction, reward sensitivity, and impulsivity. One interpretation is that these factors reflect inherent traits that predispose to risky substance use in general, a notion examined in the present study. Alexithymia, everyday frontal lobe functioning, sensitivity to reward and punishment, and impulsivity were examined in 138 young adult cannabis users who were divided into Low Risk (n = 99) and Risky (n = 39) users according to their Cannabis Use Disorder Identification Test (CUDIT) scores. Risky cannabis use was significantly positively associated with alexithymia, multiple signs of frontal lobe dysfunction in everyday life, and impulsivity. A broader pattern of dysfunction was indicated for risky cannabis use than for risky alcohol use in this sample. Findings are interpreted as likely reflecting not only inherent traits that predispose to risky substance use in general, but also perhaps residual effects of recent heavy cannabis use in the Risky user group. Longitudinal research is needed to disentangle these competing possibilities.
