Alexithymia in patients with substance use disorders: state or trait?

Psychological dimensions in alcohol use disorder: comparing active drinkers and abstinent patients

Background

Alcohol use disorder (AUD) is a major public health concern due to its various physical, psychological, and social consequences. Despite regulatory differences, abstinence remains the primary treatment objective. Addressing the multifaceted nature of alcohol use disorder requires a comprehensive approach.

Methods

150 AUD patients (66%male) with a mean age of 54.10 ± 11.3 years were recruited for the study. Depression, impulsivity, alexithymia, and hopelessness were assessed to determine if there were significant differences in these dimensions between abstinent (N=72) and active drinkers (N=78).

Results

The study found significant differences in the psychological dimensions scores, active drinkers exhibited higher levels of depression, impulsivity, alexithymia, and hopelessness compared to abstinent patients.

Conclusion

Treatment outcomes for patients with AUD vary between regulatory agencies, but abstinence remains the safest and most preferred objective in managing AUD. Prioritizing abstinence-oriented interventions is crucial for achieving long term recovery and minimizing relapse risk. These results emphasize the intricate relationship between AUD and mental health issues, highlighting the need for comprehensive interventions addressing both alcohol consumption and associated psychological distress. Promoting abstinence (or at least reducing alcohol consumption) not only preserves mental health but also prevents life-threatening consequences such as suicide.

Alexithymia in gaming addiction and engagement

BACKGROUND

It has been suggested that alexithymia plays a significant role in substance and behavioral addictions. However, only a handful of studies investigated this construct in relation to gaming addiction, and no study analyzed its differential effect on gaming engagement and addiction.

METHODS

A total of u adult gamers (Mage = 26.04, SD = 5.78, 94 % male) completed a questionnaire that included the Toronto Alexithymia Scale (and its subscales of difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking), the Addiction-Engagement Questionnaire, and additional questions about gender, age, and time spent gaming. Structural equation modeling was used as the main analytical strategy.

RESULTS

Difficulty identifying feelings (β = 0.28) and externally oriented thinking (β = 0.19) showed a significant positive effect on gaming addiction. Contrary to addiction, externally oriented thinking showed a significant negative effect (β = -0.21) on gaming engagement. No other alexithymia subscales were significant. The model with alexithymia explained 32.7 % of the variance in gaming addiction while only 10.4 % of gaming engagement.

CONCLUSIONS

Alexithymia is a strong predictor of gaming addiction. Gaming engagement seems to be a qualitatively different phenomenon that shows an opposite association with alexithymia than gaming addiction. However, both are related to increased time spent gaming. This suggests a need to distinguish between problematic vs. non-problematic excessive gaming as they have different associations with affect dysregulation.

Investigating Alexithymia as a Moderator of Outcomes in a Randomized Controlled Trial of an Online Intervention for Co-Occurring Depression and Hazardous Alcohol Use: Enquête sur l'alexithymie en tant que modérateur des résultats dans un essai randomisé contrôlé d'une intervention en ligne pour la dépression concomitante et la consommation dangereuse d'alcool

OBJECTIVE

Alexithymia is characterized by difficulty identifying and/or describing emotions, reduced imaginal processes, and externally oriented thinking. High levels of alexithymia may increase the challenge of supporting individuals with co-occurring depression and hazardous alcohol use. This secondary analysis sought to investigate whether or not alexithymia moderated the outcomes of an online intervention for depression and alcohol use.

METHOD

As part of a randomized controlled trial, 988 participants were randomly assigned to receive an intervention dually focused on depression and alcohol use, or an intervention only focused on depression. The pre-specified mediation hypothesis was that changes in drinking at 3 months follow-up would effect the association between the intervention and change in depression at 6 months. This secondary analysis extends the investigation by adding alexithymia as a moderator.

RESULTS

The current analysis demonstrated that including alexithymia as a moderator resulted in a conditional direct effect. Specifically, there was an intervention effect where participants who received the combined depression and alcohol intervention had larger improvements in their depression scores at 6 months, but this was only when their alexithymia score at baseline was also high (60.5 or higher).

CONCLUSION

These results suggest that treatment planning and intervention effectiveness could be informed and optimized by taking alexithymia severity into consideration. This is especially merited as alexithymia can contribute to the weaker therapeutic alliance, more distress and dysphoria, shorter periods of abstinence, and more severe depression, compounding the complexity of supporting individuals with comorbid conditions. More research is needed to systematically investigate these possible modifying effects.

PLAIN LANGUAGE TITLE

Does difficulty identifying/describing emotions or externally-oriented thinking influence the effectiveness of an intervention among people with both depression and hazardous alcohol use?

Longitudinal patterns of alcohol use and psychological symptoms during COVID-19 pandemic and role of alexithymia: A latent transition analysis in the FinnBrain Birth Cohort Study

BACKGROUND

The COVID-19 pandemic has been posing widespread influence on mental well-being. However, research on the dynamic relations between alcohol use and psychological symptoms in the context of the pandemic and the role of alexithymic traits in predicting the development of mental health problems longitudinally remains scarce.

METHODS

Latent profile and transition analyses were conducted to model the longitudinal patterns of transitions in the profiles of alcohol use and psychological symptoms across 10 months during the pandemic (from May 2020 to March 2021) and to investigate the role of alexithymia and its dimensions Difficulty Identifying and Describing Feelings (DIF and DDF), and Externally Oriented Thinking (EOT) in 720 parents from the FinnBrain Birth Cohort Study.

RESULTS

Three profiles, Risky Drinking, Distressed Non-Risky Drinking, and Non-Distressed, Non-Risky Drinking, and their transitions were identified. The role of alexithymia appeared to be stronger in Risky Drinking than Non-Distressed, Non-Risky Drinking. DIF predicted the development of symptoms in Risky Drinking, whereas DDF predicted Risky Drinking remaining stable over time and showed a trend towards psychological distress in Risky Drinking and Non-Distressed, Non-Risky Drinking. EOT was more likely to be a risk factor for Risky Drinking remaining constant and Non-Distressed, Non-Risky Drinking becoming Risky Drinking.

LIMITATIONS

This study was mainly limited by the generalizability of the findings.

CONCLUSIONS

Our findings add deeper insights into the longitudinal development of alcohol use and psychological symptoms as well as evidence on the role of alexithymia in shaping mental health, providing implications for tailoring clinical preventive and therapeutic measures.

Social cognition in chronic migraine with medication overuse: a cross-sectional study on different aspects of mentalization and social relationships

BACKGROUND

Social cognition refers to all mental operations to decipher information needed in social interactions. Here we aimed to outline the socio-cognitive profile of Chronic Migraine with Medication Overuse (CM + MO), given they are recognized to be at risk of socio-cognitive difficulties. Given the multidimensionality of this construct, we considered: (1) socio-cognitive abilities, (2) socio-cognitive beliefs, (3) alexithymia and autism traits, and (4) social relationships.

METHODS

Seventy-one patients suffering from CM + MO, 61 from episodic migraine (EM), and 80 healthy controls (HC) were assessed with a comprehensive battery: (1) the Faux Pas test (FP), the Strange Stories task (SS), the Reading Mind in the Eyes test (RMET), (2) the Tromsø Social Intelligence Scale, (3) the Toronto Alexithymia Scale, the Autism Spectrum Quotient, (4) the Lubben Social Network Scale, the Friendship Scale.

RESULTS

CM + MO: (1) performed similar to EM but worse than HC in the FP and SS, while they were worse than EM and HC in the RMET; (2) were similar to EM and HC in social intelligence; (3) had more alexithymic/autistic traits than EM and HC; (4) reported higher levels of contact with their family members but felt little support from the people around them than HC.

CONCLUSIONS

CM + MO results characterized by a profile of compromised socio-cognitive abilities that affects different dimensions. These findings may have a relevant role in multiple fields related to chronic headache: from the assessment to the management.

A narrative review of outcome measures used in drug and alcohol inpatient withdrawal treatment research

ISSUES

Assessing drug and alcohol inpatient withdrawal treatment programs is important, as these represent a first step of treatment among people with alcohol and drug problems. However, there are many ways of measuring outcomes making it difficult for service providers to decide which domains and methods to use. This narrative review aims to clarify frequencies of the domains and methods used to assess withdrawal treatment outcomes.

APPROACH

We reviewed published studies that examined outcomes of inpatient drug and alcohol withdrawal treatment. The types of outcome measures used and the frequency of use were summarised.

KEY FINDINGS

The review showed that assessment of withdrawal treatment outcomes goes beyond traditional abstinence measures. Outcomes mainly focus on biological and psychological outcomes, with social outcomes rarely measured. Even within outcome domains (e.g., cravings), there were many assessment methods.

IMPLICATIONS

The review provides service providers with an outline of common outcome domains and measures. Given the importance of social functioning to recovery from alcohol and drug problems, greater emphasis on such measures is desirable. Future research could develop greater consensus on outcome measures for use in withdrawal management services to facilitate clarity around factors associated with treatment success.

CONCLUSION

Outcome assessment in withdrawal treatment goes beyond abstinence to include holistic measurement of biological, psychological and some social outcomes; but more work needs to be done to cohere the different assessment methods and broaden the scope to include social functioning.

Depression in Chinese men with methamphetamine dependence: Prevalence, correlates and relationship with alexithymia

BACKGROUND

The comorbidity between substance use disorder and major depressive disorder is a typical dual diagnosis in the field of substance addiction. However, the prevalence and correlates of depression in methamphetamine addicts and whether it is associated with drug craving and alexithymia have been rarely reported in the Chinese population.

METHODS

We recruited 585 methamphetamine-dependent males from a drug rehabilitation center in China and 203 healthy controls. Demographic and drug use data were collected. Depression was assessed using the Mini International Neuropsychiatric Interview (M.I.N·I.). Methamphetamine cravings and alexithymia were assessed using the Desire for Drugs Questionnaire (DDQ) and the Toronto Alexithymia Scale (TAS).

RESULTS

The prevalence rate of depression in methamphetamine-dependent men was 16.58 % (97/585). The scores of DDQ desire and intention, DDQ negative reinforcement, total DDQ, difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and total TAS score of depressed patients were higher than those of non-depressed patients. However, only DDQ negative reinforcement score, DIF, DDF, and total TAS score remained significant after Bonferroni correction. Additionally, logistic regression analysis found that age, DIF score, and DDQ negative reinforcement score were significant factors contributing to depression in methamphetamine-dependent men.

CONCLUSION

Our findings suggest that the prevalence of depression is significantly higher in methamphetamine-dependent men than in the healthy Chinese population. Furthermore, age, components of alexithymia and drug craving are risk factors for depression in methamphetamine addicts.

Association between alexithymia and substance use: A systematic review and meta-analysis

Alexithymia has been associated with substance use, but the magnitude of the association has not been evaluated and sub-group differences, if any, are unknown. The aim of this meta-analysis is to systematically review the association between alexithymia and substance use (alcohol or illicit drugs). We identified studies through a systematic review of PubMed and Web of Science and obtained a total of 52 publications using the Toronto Alexithymia Scale-20 scale. Random effects meta-analysis was used to evaluate the overall and sub-group associations. Of the studies, 50 were cross-sectional and two longitudinal. Alexithymia was associated with any substance use (Cohen's d = 0.62, 95% confidence interval [CI] 0.49-0.76), with little difference between estimates for use of alcohol or illicit drugs. A stronger association was observed for the alexithymia dimension "Difficulty in Identifying Feelings" (d = 0.64, 95% CI = 0.47-0.81) and "Difficulty in Describing Feelings" (d = 0.44, 95% CI = 0.32-0.55) than for "Externally Oriented Thinking" (d = 0.19, 95% CI = 0.09-0.28). The association was stronger in studies with clinical patient populations (d = 0.83, 95% CI = 0.62-1.05) than in those investigating general or student populations, and in studies with a majority of male rather than female participants. These findings suggest a strong overall association between alexithymia and substance use and a very strong association among clinical patient populations. The association may be stronger with the emotion-related dimensions than with the cognition-related dimension of alexithymia. As nearly all the studies were cross-sectional, more longitudinal studies are needed.

Alexithymia and internet gaming disorder in the light of depression: A cross-sectional clinical study

BACKGROUND

Social and emotional deficits are assumed to be involved in the development and maintenance of internet gaming disorder (IGD). Alexithymia refers to a personality construct, which is characterized by deficits in emotional awareness and processing. The constructs of alexithymia and depression share similarities, and depression is a common comorbidity of IGD patients. The aim of this study was to analyze the relationship between alexithymia and IGD when controlling for depression symptom severity. Moreover, we compared alexithymia traits of IGD patients with those of non-pathological video gamers.

METHODS

In a cross-sectional study n = 38 male IGD patients (EG) were recruited at specialized healthcare services in Germany. In addition, n = 39 male non-pathological video gamers (CG) were recruited via social media and bulletin board announcement. Both groups completed questionnaires measuring alexithymia (TAS-20), depression symptom severity (BDI) and IGD severity (s-IAT).

RESULTS

Alexithymia and depression symptom severity both predicted IGD severity. Yet, when including both factors in multiple regression analysis, only alexithymia predicted IGD severity. The prevalence of alexithymia in the EG was 34.2 % (n = 13). None of the non-pathological video gamers scored above the cut-off indicating alexithymia. IGD patients showed higher traits of alexithymia in general and on each subscale, irrespective of whether or not they were currently consuming video games. As previously observed, depression symptom severity was significantly greater in IGD patients compared to healthy video gamers. Yet, group differences in alexithymia traits remained stable, with a ~29 % decrease of effectiveness in the relationship, when controlling for depression symptom severity and sociodemographic factors.

CONCLUSION

The results reveal that alexithymia is associated with and predicts IGD severity independently of depression symptom severity. Moreover, alexithymia is highly prevalent in IGD patients.

The process of emotion identification: Considerations for psychiatric disorders

Emotional regulation is important for mental health and behavioral regulation. A relevant precursor to emotional regulation may involve identification of one's emotions. Here, we propose a model of seven components that may provide a foundation for emotion identification. These factors include baseline mood, monitoring, physiological responses, interoception, past personal experiences regarding emotions/metacognition, context, and labeling. We additionally examine how deficits in different components may contribute to the concept of alexithymia, which is defined by difficulty identifying and describing one's own emotions. Ultimately, we explore how the model may support a relationship between specific psychiatric disorders and alexithymia. The proposed model may help explain emotional identification impairment in multiple psychiatric disorders and guide future research and treatment development efforts.

Models predicting the role of emotion reactivity in the link between reasons for not using and lifetime substance use

Objective Substance use peaks in emerging adulthood, with evidence suggesting that college-attending emerging adults have a higher rate of substance use than their non-college attending peers. More insight into the factors that might contribute to substance use among college-attending emerging adults is needed. The current study examined the moderating role of emotion reactivity in the link between perceived importance of reasons for not using substances and lifetime marijuana and alcohol use. Participants: 440 undergraduate students under the age of 21 (M = 18.67, 47.7% Male) from a large Midwestern university participated in the study. Methods Participants responded survey items assessing reasons for not using, lifetime marijuana and alcohol use, and emotion reactivity. Results: Emotion reactivity only moderated the link between reasons for not using alcohol (i.e., reasons related to self-control) and lifetime alcohol use. Conclusions: Future research on reasons for not using is warranted. Implications for preventative interventions are discussed.

The role of alexithymia and autistic traits in predicting quality of life in an online sample

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.

Atypical interoception as a common risk factor for psychopathology: A review

The inadequacy of a categorial approach to mental health diagnosis is now well-recognised, with many authors, diagnostic manuals and funding bodies advocating a dimensional, trans-diagnostic approach to mental health research. Variance in interoception, the ability to perceive one's internal bodily state, is reported across diagnostic boundaries, and is associated with atypical functioning across symptom categories. Drawing on behavioural and neuroscientific evidence, we outline current research on the contribution of interoception to numerous cognitive and affective abilities (in both typical and clinical populations), and describe the interoceptive atypicalities seen in a range of psychiatric conditions. We discuss the role that interoception may play in the development and maintenance of psychopathology, as well as the ways in which interoception may differ across clinical presentations. A number of important areas for further research on the role of interoception in psychopathology are highlighted.

Alexithymia in Patients With Substance Use Disorders and Its Relationship With Psychiatric Comorbidities and Health-Related Quality of Life

Background: Alexithymia frequently correlates with several psychiatric disorders, including substance use disorder (SUD). However, most studies reporting the associations between alexithymia and psychiatric disorders have been performed in populations without SUD. This research, therefore, evaluates alexithymia in Spanish patients with SUD and the relationship among alexithymia, psychiatric comorbidities, psychological symptoms/traits, SUD variables, and health-related quality of life (HRQoL). Methodology: A cross-sectional study was conducted with 126 Spanish outpatients with SUD (75.4% males; mean age 43.72 ± 14.61 years), correlating their alexithymia levels (using the Toronto Alexithymia Scale 20 [TAS-20]) to their psychiatric comorbidities, psychological symptoms/traits, SUD variables, and HRQoL. Results: Alexithymia was significantly higher in patients who had cannabis use disorder. Higher alexithymia scores were also related to higher levels of depression, anxiety, impulsivity, and lower HRQoL. After multivariate analysis, trait anxiety, impulsivity, and the physical component summary of the HRQoL were found to be independently related to alexithymia. Conclusions: SUD patients with higher alexithymia levels have more frequently psychiatric comorbidities, present specific psychological features, and have worse HRQoL. Hence, it is important to evaluate these factors and offer more accurate psychotherapeutic approaches for this patient population.

Developing Emotional Skills and the Therapeutic Alliance in Clients with Alexithymia: Intervention Guidelines

Despite being a longstanding and well-established concept, alexithymia is unfamiliar for many clinicians. This article aimed to address the alexithymia concept from a clinical perspective based on a review of the research on alexithymia intervention. Several strategies are proposed to help clinicians better work with alexithymic clients in psychotherapy. Alexithymia assessment, its impact on the therapeutic alliance, and the difficulties in emotional tasks are highlighted points. Considering alexithymia will inform clinicians' current diagnosis and conceptualization and provide specific targets and venues for intervention, increasing the effectiveness of psychotherapy.

Alexithymia and pain experience among patients using methadone-maintenance therapy

BACKGROUND

Alexithymia, difficulty identifying and describing one's emotions coupled with a tendency to externalize, is a potentially important yet understudied treatment target for patients with opioid use disorder. The aim of this study was to examine the role of alexithymia in pain experience among individuals with opioid use disorder.

METHODS

One-hundred-and-sixty-four patients receiving methadone maintenance treatment completed a battery of self-report measures related to alexithymia, drug use, and pain experiences. Comparisons were performed on the full sample between those with or without clinically significant levels of alexithymia. For a subsample reporting pain (n = 138), intercorrelations were performed to test whether drug use history, pain catastrophizing, pain acceptance, and alexithymia were related to pain severity and pain interference. Regression analyses were performed to test for serial mediation of pain catastrophizing and pain acceptance on the relationship between alexithymia and pain interference in this subsample.

RESULTS

Individuals with alexithymia showed increased pain catastrophizing and interference, and intercorrelations indicated that increased alexithymia was associated with increased pain interference, more pain catastrophizing, and reduced pain acceptance. A serial regression model among a subset of patients with pain indicated that pain catastrophizing and pain acceptance mediated the effect of alexithymia on pain interference.

CONCLUSIONS

These findings suggest that alexithymia, as well as both pain catastrophizing and pain acceptance, contribute to interference associated with pain and are potentially important intervention targets among methadone-treated patients with pain.

Factor Structure and Psychometric Properties of a New Scale to Assess Alexithymia-Like Features in Japanese Youth

BACKGROUND

Studies of alexithymia have primarily targeted adult populations. Although some recent studies of alexithymia have focused on children and young adolescents, the literature is not sufficient for development of an assessment tool. The aim of this study was to develop, and evaluate the psychometric properties of, a new scale to measure alexithymia-like features in young adolescents.

METHODS

A total of 1,444 Japanese junior high school students (701 males, 743 females; age range 12-15; mean [SD] age, 13.37 [0.98] years) participated in 2 surveys conducted at their own schools.

RESULTS

First, exploratory factor analysis of the first survey data (n=981) demonstrated that this new scale had a unifactor structure, as determined by minimum average partial analysis and parallel analysis. Second, confirmatory factor analysis of the second survey data (n=463) confirmed the unifactor structure of this new scale and acceptable goodness of model fit. The new scale had modest internal consistency.

CONCLUSIONS

The correlations of this new alexithymia scale with related variables were weak but significant, in accordance with our hypothesis. The scale had acceptable reliability and convergent validity and thus might be useful for measuring alexithymic tendency in young adolescents.

Music Therapy to Regulate Arousal and Attention in Patients With Substance Use Disorder and Posttraumatic Stress Disorder: A Feasibility Study

Patients diagnosed with both substance use disorder (SUD) and posttraumatic stress disorder (PTSD) often experience hypervigilance, increased fear, and difficulties regulating emotions. This dual diagnosis increases treatment complexity. Recently, a short-term music therapy intervention for arousal and attention regulation (the SMAART intervention) was designed based on neurobiological findings. Twelve patients with SUD and PTSD (50% females) in outpatient treatment participated in six weekly one-hour sessions of the SMAART intervention. Six patients completed the study. PTSD symptom severity was evaluated with the Posttraumatic Stress Disorder Symptom Scale Interview for DSM-5 (PSSI-5) pre- and post-intervention, and sustained attention was evaluated with the Bourdon-Wiersma (BW) test. A significant difference in measurements for the PSSI-5 overall symptom severity was found pre- and post-intervention. Furthermore, participants showed significant improvement on subscales of hyperarousal, mood and cognition, and attention. The BW test completion time decreased significantly. Two participants dropped out before the end of the intervention due to craving. Concerning future research, it is recommended to define the role of the music more explicitly and to change the design to a randomized controlled trial. A risk for future larger studies is a high dropout rate (50%). Several limitations of the study are discussed.

Alexithymia, resilience, somatic sensations and their relationships with suicide ideation in drug naïve patients with first-episode major depression: An exploratory study in the "real world" everyday clinical practice

AIM

The present study is aimed at revaluating alexithymia, somatic sensations, resilience and their relationships with suicide ideation in drug naïve adult outpatients suffering from first episode major depression (MD).

METHODS

Data of 103 adult outpatients (49 men, 56 women) with a diagnostic and statistical manual of mental disorders, 4th edition, text revision (DSM-IV-TR) diagnosis of MD were analysed. Alexithymia was measured using the 20-item Toronto Alexithymia Scale (TAS-20) and resilience with the 25 items Connor-Davidson Resilience Scale (CD-RISC) whereas depression was evaluated using the 17-item Hamilton Depression Rating Scale, somatic sensations with the Body Sensations Questionnaire and suicide ideation with Scale of Suicide Ideation (SSI).

RESULTS

Gender comparisons between all demographic and clinical variables showed no significant differences in all variables. Subjects who were found positive for alexithymia showed higher scores on all clinical variables controlling for age, gender and duration of the current episode. In a linear regression model, lower scores on CD-RISC and Difficulty in Identifying Feelings dimension of TAS-20 were significantly predictive of higher scores on SSI.

CONCLUSIONS

Alexithymia and low resilience were significant predictors of increased suicide ideation in a first MD episode. However, study limitations must be considered and future research needs are being discussed.

The Great Disrupter: Relationship of Alexithymia to Emotion Regulation Processes and Smoking among Pregnant Women

Background: Many women continue to smoke during pregnancy, despite known risks, often in response to negative affect. Recent scholarship has begun to examine factors that decrease the success of behavioral treatments for smoking cessation in pregnancy, which are the preferred interventions. Alexithymia is one factor that may interfere with smoking cessation interventions. Alexithymia restricts access to emotional information and increases propensity toward maladaptive behaviors, including smoking. However, mechanisms underlying such effects are largely unknown. Objectives: Using data from a longitudinal treatment study, the present research examined difficulties with emotion regulation as a potential mechanism linking alexithymia and smoking. Pregnant smokers (n = 73; mean age = 24.78; SD = 4.50) completed measures related to alexithymia, smoking, emotion regulation, depression, anxiety, and anger at baseline and then again following eight sessions of Cognitive-Behavioral Smoking Cessation Treatment. Results: Nearly 40% of the sample met the criteria for alexithymia. The alexithymia group reported higher depression, anxiety, and anger. They also reported more difficulties with emotion regulation. In a path analysis, baseline alexithymia had a significant positive indirect effect on number of cigarettes smoked at the end of treatment through difficulties with emotion regulation. Conclusions/Importance: Similar to other studies, alexithymia limits the understanding of emotional information necessary for selection and implementation of adaptive coping responses. Our results extend the literature by suggesting that smoking may be an attempt to manage undifferentiated and unpleasant sensations created by alexithymia.

Auditory sensation with affective agnosia: A prevalence of alexithymia among tinnitus patients

OBJECTIVES

The aim of the present study was to determine the prevalence and association of alexithymia, depression, and anxiety in patients affected by tinnitus.

METHODS

The study was conducted among the patients referred for audiometric evaluation for tinnitus. They were further evaluated with the Hospital Anxiety and Depression Scale, the Tinnitus Handicap Inventory, and the Toronto Alexithymia Scale. Analysis was done for prevalence and the sample was categorized as high and low tinnitus handicap subgroups, and mean scores of alexithymia, anxiety, and depression were compared.

RESULTS

A total of 70 patients (55.7% - male and 44.3% - female) with a mean age of 33.17 ± 12.24 years were finally analyzed. The severity of tinnitus was most severe (34.3%), followed by moderate (20%), catastrophic (18.6%), mild (17.1%), and slight (10%). The prevalence of alexithymia, anxiety, and depression among patients of tinnitus was found to be 65.7%, 37.1%, and 20%, respectively. The high tinnitus handicap group showed higher scoring on total alexithymia score, anxiety, and depression and higher scoring with describing emotion and identification of emotion, but there was no difference for the subscale of externally oriented thinking.

CONCLUSIONS

The study found a prevalence of alexithymia, anxiety, and depression as 65.7%, 37.1%, and 20%, respectively, among patients of tinnitus, and problem of describing and identification of emotion are associated with higher tinnitus handicap.

The prediction of alexithymia as a state or trait characteristic in patients with substance use disorders and PTSD

Alexithymia is common in patients with a substance use disorder (SUD) and is possibly a negative prognostic factor in their treatment. The aim of this study was twofold. First, we explored whether SUD patients with posttraumatic stress disorder (PTSD) are more alexithymic than SUD patients without PTSD. Next, we explored whether trait and state-related parts of alexithymia could be differentiated in these patients. This phenomenon was studied in 197 SUD patients with the Toronto Alexithymia Scale-20 (TAS-20); Clinician Administered PTSD Scale; Self-Report Inventory for PTSD; Traumatic Experiences Checklist; European Addiction Severity Index; and the Depression, Anxiety and Stress Scale in a cross-sectional design. SUD patients with current PTSD showed more alexithymic characteristics than patients without PTSD or with previous lifetime/not current PTSD. The severity of PTSD complaints; alcohol addiction; and the combination of depression, anxiety and stress symptoms, all of which are more related to alexithymia as a state, explained 38.1% of the TAS-20. In conclusion, we advise that SUD patients be assessed for alexithymia and that its degree is taken into account. We also tentatively assume that a considerable part of alexithymia is more state- than trait-related in these patients.

Neuro-cognitive correlates of alexithymia in patients with circumscribed prefrontal cortex damage

Alexithymia has been extensively reported in studies of psychiatric patients. However, little attention has been paid regarding its occurrence in the context of patients with circumscribed prefrontal cortex lesions. Moreover, the neuro-cognitive impairments that lead to alexithymia remain unclear and limited numbers of studies have addressed these issues. The authors investigated the impact of prefrontal cortex lesions on alexithymia and its neuro-cognitive correlates in a population of 20 patients with focal frontal lesions, 10 patients with parietal lesions and 34 matched control participants. Alexithymia was screened using the Toronto Alexithymia Scale (TAS-20) and executive functions were assessed using a large battery of executive tasks that address inhibition, flexibility and the planning process. Results showed that patients with prefrontal cortex damage showed significantly increased difficulty in facets of identifying feelings (DIF) and externally oriented thinking (EOT) on TAS-20, compared to parietal patients and control participants. Moreover, both correlation and regression analysis revealed that higher alexithymia levels on the three facets of TAS-20 were consistently but differentially associated with impairment in inhibition, flexibility and planning tasks for frontal patients and both control groups. These findings provide clinical evidence of the implication of prefrontal cortex damage and executive control in alexithymia. Our results were also discussed in the light of the cognitive appraisal concept as a mechanism involved in emotion episode processing. This study suggests that increased neuropsychological attention should be directed to the relation between the neuro-cognitive model of executive functions and cognitive appraisal theory in processing emotion.

Alexithymia in Young Adults With Substance Use Disorders: Critical Issues About Specificity and Treatment Predictivity

Several studies have reported high rates of alexithymia in drug-dependent individuals, but supporting evidence attests association between alexithymia and a variety of psychiatric disorders, raising doubts about its specificity. Moreover, controversies are emerging about alexithymia assessment: self-report measures present shortcomings with respect to discriminant validity and reliability. As regards treatment for substance use disorders (SUDs), alexithymia has been linked to poorer outcomes, but the results are inconsistent. The aim of the present study is to investigate alexithymia in substance-dependent young adults by examining: (a) the specificity of alexithymia in drug-dependent inpatients, compared to healthy individuals and patients with psychiatric disorders (behavioral and emotional disorders) and (b) the predictivity of alexithymia in determining treatment outcomes in terms of relapses, drop-outs from treatment and the rate of relapse per month of treatment. Two studies were conducted to fulfill these aims: Study 1 and Study 2. Study 1 involved 90 late adolescents, aged 17-21. To fulfill the first aim, 30 inpatients diagnosed with SUD were compared with 30 healthy controls and 30 individuals referred to an outpatient neuropsychiatric unit (a). The participants completed the Toronto Alexithymia Scale-20 (TAS-20) and the Symptom Checklist-90-Revised (SCL-90-R). The results indicated that both clinical groups reported higher TAS-20 scores than the non-clinical subjects, but they did not differ from each other (a); moreover, a large correlation was detected between alexithymia and depressive symptoms, as assessed by the SCL-90-R. Study 2 involved 55 inpatients with SUD recruited in a therapeutic community. The participants completed the TAS-20, and clinicians filled out the Observer Alexithymia Scale (OAS). No association was found between self-report and observational measures. Neither self-reported nor observed alexithymia predicted the number of relapses, drop-out from treatment, or the rate of relapses per month of treatment (b). When the interaction with gender was explored, the global score of alexithymia and the "Distant" OAS subscale predicted the number rate relapses only in males. The TAS-20 did not discriminate between the clinical groups. The limited ability of both observed and self-reported measures in predicting treatment outcome raises questions on the specificity of alexithymia among the substance-dependent inpatient population.

Traumatic Experiences, Stressful Events, and Alexithymia in Chronic Migraine With Medication Overuse

Background: Many factors are involved in the prognosis and outcome of Chronic Migraine and Medication Overuse Headache (CM+MOH), and their understanding is a topic of interest. It is well known that CM+MOH patients experience increased psychiatric comorbidity, such as anxiety, depression, or personality disorders. Other psychological factors still need to be explored. The present study is aimed to evaluate whether early life traumatic experiences, stressful life events, and alexithymia can be associated with CM+MOH.

Methods: Three hundred and thirty-one individuals were recruited for this study. They belonged to one of the two following groups: CM+MOH (N = 179; 79% females, Age: 45.2 ± 9.8) and episodic migraine (EM) (N = 152; 81% females; Age: 40.7 ± 11.0). Diagnosis was operationally defined according to the International Classification of Headache Disorders 3rd edition (ICHD-IIIβ). Data on early life (physical and emotional) traumatic experiences, recent stressful events and alexithymia were collected by means of the Childhood Trauma Questionnaire, the Stressful life-events Questionnaire, and the Toronto Alexithymia Scale (TAS-20), respectively.

Results: Data showed a higher prevalence of emotional (χ² = 6.99; d.f. = 1; p = 0.006) and physical (χ² = 6.18; d.f. = 1; p = 0.009) childhood trauma and of current stressful events of important impact (χ² = 4.42; d.f. = 1; p = 0.025) in CM+MOH patients than in EM ones. CM+MOH patients were characterized by higher difficulties in a specific alexithymic trait (Factor 1 subscale of TAS-20) [F_{(1, 326)} = 6.76, p = 0.01, η_p² = 0.02] when compared to the EM group. The role of these factors was confirmed in a multivariate analysis, which showed an association of CM+MOH with emotional (OR 2.655; 95% CI 1.153–6.115, p = 0.022) or physical trauma (OR 2.763; 95% CI 1.322–5.771, p = 0.007), and a high score at the Factor 1 (OR 1.039; 95% CI 1.002–1.078, p = 0.040).

Conclusions: Our findings demonstrated a clear relationship between CM+MOH and life traumas, stressful events, and alexithymia. These observations have a relevant role in multiple fields of related to chronic headache: from the management to the nosographic framing.

An evaluation of the absolute and relative stability of alexithymia over 11years in a Finnish general population

OBJECTIVE

We investigated if alexithymia, a personality construct with difficulties in emotional processing, is stable in the general population.

METHODS

Altogether 3083 unselected subjects aged 30 and older in Finland completed the 20-item Toronto Alexithymia Scale (TAS-20) in the longitudinal Health 2000 and Health 2011 general population surveys (BRIF8901). The stability of alexithymia at the 11-year follow-up was assessed with t-tests, correlations, and separate linear regression models with base-line and follow-up age, gender, marital status, education, and 12-month depressive and anxiety disorders as confounders.

RESULTS

The mean score (SD) of the TAS-20 for the whole sample was 44.2 (10.4) in 2000 and 44.2 (10.9) in 2011 (p=0.731). The mean score of the TAS-20 subscale Difficulty Identifying Feelings increased by 0.3 points, Difficulty Describing Feelings decreased by 0.6 points and Externally Oriented Thinking increased by 0.3 points. The effect sizes of the changes varied from negligible to small. Age had little effect except for the group of the oldest subjects (75-97years): the TAS-20 mean (SD) score was 49.1 (10.1) in 2000 and 53.1 (10.3) in 2011 (p<0.001), the effect size for the increase was medium. TAS-20 score in 2000 explained a significant proportion of variance in TAS-20 score in 2011. Controlling for all baseline confounders improved the model incrementally; the same applied to controlling for confounders at follow-up. Baseline depression or anxiety disorders were not associated with the TAS-20 scores in 2011, whereas current diagnoses were.

CONCLUSIONS

According to our large longitudinal study both the absolute and relative stability of alexithymia assessed with the TAS-20 are high in the adult general population.

Is alexithymia related to cannabis use disorder? Results from a case-control study in outpatient adolescent cannabis abusers

OBJECTIVE

In recent decades, alexithymia has been considered a risk factor for multiple somatic and psychiatric conditions. Yet, whereas alexithymia has been extensively studied in adults with a substance misuse, only one study has reported data on cannabis abusers from the general population. Hence, our main objective was to explore alexithymia in a clinical sample of treatment-seeking young outpatients with a DSM-IV cannabis dependence or abuse diagnosis compared to controls.

METHODS

120 young patients (95 males - mean age 17.9years (SD=2.8; 14 to 25)) with a cannabis dependence or abuse (DSM-IV-TR criteria evaluated with the MINI), seeking treatment in an addiction unit, and 110 healthy control subjects (77 males - mean age 18.2years (SD=3.4; 14 to 25)) participated in the study. They completed a battery of self-reports measuring alexithymia (TAS-20; BVAQ-B), depression (BDI-13) and state and trait anxiety (STAI).

RESULTS

35.3% of cannabis users were alexithymic, and logistic regression analysis showed that the alexithymic components of difficulties identifying and describing feelings combined with trait anxiety predicted group membership.

CONCLUSION

This first study on young cannabis abusers and dependent subjects further emphasizes the importance of considering the affective style, and particularly the anxious temperament and alexithymia features, as factors associated with substance misuse during late adolescence.

Alexithymia: a general deficit of interoception

Alexithymia is a sub-clinical construct, traditionally characterized by difficulties identifying and describing one's own emotions. Despite the clear need for interoception (interpreting physical signals from the body) when identifying one's own emotions, little research has focused on the selectivity of this impairment. While it was originally assumed that the interoceptive deficit in alexithymia is specific to emotion, recent evidence suggests that alexithymia may also be associated with difficulties perceiving some non-affective interoceptive signals, such as one's heart rate. It is therefore possible that the impairment experienced by those with alexithymia is common to all aspects of interoception, such as interpreting signals of hunger, arousal, proprioception, tiredness and temperature. In order to determine whether alexithymia is associated with selectively impaired affective interoception, or general interoceptive impairment, we investigated the association between alexithymia and self-reported non-affective interoceptive ability, and the extent to which individuals perceive similarity between affective and non-affective states (both measured using questionnaires developed for the purpose of the current study), in both typical individuals (n = 105 (89 female), mean age = 27.5 years) and individuals reporting a diagnosis of a psychiatric condition (n = 103 (83 female), mean age = 31.3 years). Findings indicated that alexithymia was associated with poor non-affective interoception and increased perceived similarity between affective and non-affective states, in both the typical and clinical populations. We therefore suggest that rather than being specifically associated with affective impairment, alexithymia is better characterized by a general failure of interoception.

Alexithymia and Addiction: A Review and Preliminary Data Suggesting Neurobiological Links to Reward/Loss Processing

Alexithymia, characterized by impairments in emotional awareness, is common among individuals with substance use disorders. Research on alexithymia suggests that it is a trait that may contribute to substance dependence. This paper will review alexithymia as it relates to substance use and substance use disorders, considering its potential role in the maintenance and treatment of these disorders. We will then describe how neural correlates associated with alexithymia may shed light on how alexithymia relates to addiction. Finally, we present preliminary fMRI data that examines how alexithymia may relate to the neurobiological correlates of reward/loss processing in individuals with cocaine dependence. While preliminary, these findings suggest a role of alexithymia in reward anticipation in cocaine-dependent individuals.

Relationship of Alexithymia Ratings to Dopamine D2-type Receptors in Anterior Cingulate and Insula of Healthy Control Subjects but Not Methamphetamine-Dependent Individuals

BACKGROUND

Individuals with substance-use disorders exhibit emotional problems, including deficits in emotion recognition and processing, and this class of disorders also has been linked to deficits in dopaminergic markers in the brain. Because associations between these phenomena have not been explored, we compared a group of recently abstinent methamphetamine-dependent individuals (n=23) with a healthy-control group (n=17) on dopamine D2-type receptor availability, measured using positron emission tomography with [(18)F]fallypride.

METHODS

The anterior cingulate and anterior insular cortices were selected as the brain regions of interest, because they receive dopaminergic innervation and are thought to be involved in emotion awareness and processing. The Toronto Alexithymia Scale, which includes items that assess difficulty in identifying and describing feelings as well as externally oriented thinking, was administered, and the scores were tested for association with D2-type receptor availability.

RESULTS

Relative to controls, methamphetamine-dependent individuals showed higher alexithymia scores, reporting difficulty in identifying feelings. The groups did not differ in D2-type receptor availability in the anterior cingulate or anterior insular cortices, but a significant interaction between group and D2-type receptor availability in both regions, on self-report score, reflected significant positive correlations in the control group (higher receptor availability linked to higher alexithymia) but nonsignificant, negative correlations (lower receptor availability linked to higher alexithymia) in methamphetamine-dependent subjects.

CONCLUSIONS

The results suggest that neurotransmission through D2-type receptors in the anterior cingulate and anterior insular cortices influences capacity of emotion processing in healthy people but that this association is absent in individuals with methamphetamine dependence.

Alexithymia level and response to computer-based training in cognitive behavioral therapy among cocaine-dependent methadone maintained individuals

BACKGROUND

Alexithymia, a characteristic marked by poor ability to identify, define and communicate emotions, has been associated with poorer treatment outcome, including traditional clinician delivered CBT. Computerized cognitive behavioral therapy (CBT4CBT), an effective adjunct to treatment, may provide a means of conveying skills without requiring interaction with a clinician.

METHODS

Seventy-three methadone maintained, cocaine dependent individuals participating in an 8-week randomized clinical trial comparing standard methadone maintenance to methadone maintenance plus CBT4CBT completed the Toronto Alexithymia Scale (TAS-20) at pretreatment, post-treatment, and follow-ups conducted one, two, and 6 months after treatment.

RESULTS

There were no statistically significant differences on baseline TAS-20 scores by multiple demographic and substance use variables including gender and substance use severity. Higher TAS-20 scores were associated with somewhat higher levels of distress as measured by the Beck Depression Inventory and multiple Brief Severity Index scales. TAS-20 scores remained relatively stable throughout the duration of treatment and follow-up. Indicators of treatment process, including treatment retention, adherence and therapeutic alliance, were not significantly correlated with TAS-20 scores. There was a significant interaction of alexithymia and treatment condition, such that individuals with higher baseline scores on the TAS-20 submitted significantly higher percentages of cocaine-negative urine toxicology specimens and reported a higher percentage of abstinence days, and longer periods of consecutive abstinence within treatment when assigned to CBT4CBT compared with treatment as usual.

CONCLUSIONS

These findings suggest that individuals with increased alexithymia may benefit from computerized CBT; possibly via reduced demands on interpersonal skills and interactions associated with computerized therapies.

Development of alexithymic personality features

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