Relationships among alexithymia, therapeutic alliance, and psychotherapy outcome in major depressive disorder

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?

Case report: Short-term psychotherapy for alexithymia in a patient with generalized anxiety disorder

Alexithymia is common among patients with generalized anxiety disorder (GAD) and may negatively affect the efficacy of treatment. This case report described a sole short-term psychotherapy focusing on alexithymia for a GAD patient. The intervention extends over 3 weekly 50-minute sessions and incorporates components of: (a) understanding the basic categories of emotions and the importance of processing them consciously and building one's own vocabulary of emotions; (b) developing skills in identifying and labeling emotions and learning to register both positive and negative emotions in daily life; (c) observing and interpreting emotion-related body sensations and learning to get in touch with, be empathetic to, and take care of one's own inner feelings in daily life. The Hamilton Rating Scale for Depression (HRSD), Hamilton Anxiety Rating Scale (HAMA), and Toronto Alexithymia Scale (TAS) were used to evaluate depression, anxiety, and alexithymia before and after the sessions. The results suggested that the treatment was not only effective in reducing alexithymia helping the patient to clarify, identify and describe her feelings, but also effective in reducing anxiety and depression.

The effects of visual art therapy on adults with depressive symptoms: A systematic review and meta-analysis

Depression constitutes a pervasive global mental health concern and stands as a principal determinant of elevated suicide rates worldwide. Recent empirical investigations have showcased the significant potential of visual art therapy (VAT) in ameliorating symptoms among individuals with depression. Nevertheless, specific studies have yielded findings marked by inconclusiveness, underscoring the imperative need for further research to comprehensively establish its efficacy. This study is a systematic review and meta-analysis of extant research, to ascertain the efficacy and effect size of VAT as an intervention for adults with depressive symptoms. A comprehensive search was conducted across 10 databases. The search encompassed articles published from the inception of these databases up until October 18, 2023. Two researchers screened the literature in accordance with inclusion and exclusion criteria and performed a thorough quality assessment. The original data and the data obtained from the literature were extracted for further analysis. The statistical analysis of the data was performed using Stata 17.0 software. fifteen studies were included, encompassing a total of 932 participants. The outcomes of meta-analysis unveiled a statistically significant effect of VAT in diminishing depressive symptoms among adults (SMD = -0.73; 95% CI, -1.07 to -0.39; p < 0.001; 15 randomised controlled trials (RCTs); low-quality evidence). The subgroup analysis indicated that VAT exhibited heightened effectiveness among adults below 65 years of age, with interventions lasting ≤12 weeks demonstrating superior efficacy. Additionally, sensitivity analysis underscored the robustness and reliability of the findings. VAT appears to alleviate depressive symptoms among adults. Existing research indicates that the effectiveness of VAT is influenced by factors, such as intervention population characteristics and intervention duration. However, to comprehensively probe the efficacy of VAT, future studies should strive for larger sample sizes, multicentre collaborations, and long-term follow-ups.

An Examination of the Treatment Utility of the MMPI-2-RF: Prediction of Post-Treatment Depressive Symptoms and Increased Understanding of the Therapeutic Alliance in an Inpatient Mood Disorder Treatment

The study examined the ability of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) substantive scales to predict depressive symptoms in a psychiatric inpatient setting. The indirect effect of patient-rated alliance with their treatment team on these relationships was also investigated. Participants included 678 (52.5% female, 97.1% White) inpatients diagnosed with a mood disorder. MMPI-2-RF scales, Patient Health Questionnaire (PHQ-9) at intake and discharge, and Working Alliance Inventory-Short at discharge were used to test study hypotheses regarding MMPI-2-RF predictive utility and the influence of alliance. Jacobson and Truax's (1991) reliable change index (RCI) was calculated to identify those who did (74% of the sample) and did not (24%) make reliable and clinically significant depressive symptom change, and the predictive utility of MMPI-2-RF scores in distinguishing these groups was examined. MMPI-2-RF scales assessing internalizing and somatic dysfunction accounted for an additional 2% to 8% of the variance in depressive symptoms reported at discharge, above and beyond depressive symptoms reported at intake. Somatic scales were also able to differentiate groups based on clinically significant change on the PHQ-9 (small-sized effect). The relationship between MMPI-2-RF scales and depressive symptoms at discharge was indirect through alliance in 64% of models. Clinical implications are discussed.

Impact of Alexithymia on the Lipid Profile in Major Depressed Individuals

Background

The cooccurrence of major depression and dyslipidaemia is associated with negative cardiovascular outcome, which seems to justify a better identification of the factors favouring the development of dyslipidaemia in major depressed individuals. In the literature, there are arguments in favour of a special relationship between dyslipidaemia and alexithymia. However, despite a high prevalence of alexithymia in major depressed individuals, no study has investigated the impact of this personality trait on the lipid profile in this particular subpopulation. Given these elements, the aim of this study was therefore to investigate the risk of dyslipidaemia associated with alexithymia in major depressed individuals to allow better cardiovascular prevention in this subpopulation. Subjects and Methods. Demographic and polysomnographic data from 242 major depressed individuals recruited from the clinical database of the sleep laboratory were analysed. Only individuals with a diagnosis of dyslipidaemia according to the diagnostic criteria of the International Diabetes Federation at admission were included in the “dyslipidaemia” group. Logistic regression analyses were used to determine the risk of dyslipidaemia associated with alexithymia in major depressed individuals.

Results

The prevalence of dyslipidaemia was 43.8% in our sample of major depressed individuals. After adjusting for the main confounding factors, multivariate logistic regression analyses demonstrated that alexithymia was a risk factor for dyslipidaemia in major depressed individuals.

Conclusions

In this study, we found that alexithymia is a risk factor for dyslipidaemia in major depressed individuals, which seems to justify better identification and adequate management of this personality trait in order to allow a better lipid profile in this subpopulation at high cardiovascular risk.

Personalized behavior management as a replacement for medications for pain control and mood regulation

A lack of personalized approaches in non-medication pain management has prevented these alternative forms of treatment from achieving the desired efficacy. One hundred and ten female patients with fibromyalgia syndrome (FMS) and 60 healthy women without chronic pain were assessed for severity of chronic or retrospective occasional pain, respectively, along with alexithymia, depression, anxiety, coping strategies, and personality traits. All analyses were conducted following a ‘resource matching’ hypothesis predicting that to be effective, a behavioral coping mechanism diverting or producing cognitive resources should correspond to particular mechanisms regulating pain severity in the patient. Moderated mediation analysis found that extraverts could effectively cope with chronic pain and avoid the use of medications for pain and mood management by lowering depressive symptoms through the use of distraction mechanism as a habitual (‘out-of-touch-with-reality’) behavior. However, introverts could effectively cope with chronic pain and avoid the use of medications by lowering catastrophizing through the use of distraction mechanism as a situational (‘in-touch-with-reality’) behavior. Thus, personalized behavior management techniques applied according to a mechanism of capturing or diverting the main individual ‘resource’ of the pain experience from its ‘feeding’ to supporting another activity may increase efficacy in the reduction of pain severity along with decreasing the need for pain relief and mood-stabilizing medications.

Negative Emotion Differentiation Predicts Psychotherapy Outcome: Preliminary Findings

Emotion differentiation (ED), the extent to which same-valenced emotions are experienced as distinct, is considered a valuable ability in various contexts owing to the essential affect-related information it provides. This information can help individuals understand and regulate their emotional and motivational states. In this study, we sought to examine the extent to which ED can be beneficial in psychotherapy context and specifically for predicting treatment response. Thirty-two prospective patients with mood and anxiety disorders completed four daily assessments of negative and positive emotions for 30 days before receiving cognitive-behavioral treatment. Depression, stress, and anxiety symptoms severity were assessed pre- and post-treatment using self-reports and clinical interviews. We conducted a series of hierarchical regression models in which symptoms change scores were predicted by ED while adjusting for the mean and variability. We found that negative ED was associated with greater self-reported treatment response (except for anxiety) when negative emotional variability (EV) was included in the models. Probing negative ED and EV's interactive effects suggested that negative ED was associated with greater treatment response (except for anxiety) for individuals with lower EV levels. Results were obtained while controlling for mean negative affect. Our findings suggest that negative ED can benefit psychotherapy patients whose negative emotions are relatively less variable. We discuss the meaning of suppression and interactive effects between affect dynamics and consider possible clinical implications.

Relationship between alexithymia and depression: A narrative review

Alexithymia has been described as difficulty in expressing as well as experiencing feelings. It has been studied in relation with medical as well as psychological conditions and has been seen to impact treatment outcomes. The current review focuses on the relationship of alexithymia with depression and the role of culture in this relationship. The keywords for literature included terms such as depression, alexithymia, depression and alexithymia, Toronto Alexithymia Scale, assessing alexithymia and depression, and alexithymia as a trait. The main findings of the review were that alexithymia and depression are highly correlated, and severity of depression and gender are independently associated with alexithymia and may interfere with treatment outcomes.

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.

Treatment of disorders of emotional comprehension, expression, and emotional semantics

Neurological disease can impair emotional communication by several means: damaging the networks important in understanding the meaning of emotional stimuli (emotional semantics); damaging networks important in the perceptual recognition and production of emotional stimuli, and damaging the connections between networks supporting emotional semantics and recognition/production networks. Disorders of emotional expression, comprehension, and emotional semantics may improve with pharmacological or behavioral treatments. Pharmacological treatments can be used to redress naturally occurring or disease-related alterations in the computational properties of target neural systems. No drug treatment can replace a loss of cerebral knowledge related to the pathological loss of neural connectivity. Behavioral treatments that benefit either comprehension or expression of specific emotions may be of value if these emotions are particularly important in enabling human social interaction. However, behavioral treatments that achieve generalization, that is, improve performance with untrained exemplars and in daily life, are much to be preferred, even as they pose the greatest methodological challenges. This chapter will discuss possible mechanisms of generalization and then review what is known about the treatment of expressive and receptive affective aprosodia, deficits in recognition of facial emotions, and pseudobulbar affect. The final section of the chapter is devoted to a discussion of three disorders of emotional semantics, apathy, alexithymia, and impaired empathy.

Importance of telling the unutterable: Alexithymia among sexually abused children

Child maltreatment is known to be an etiological factor for developing alexithymia which refers to the difficulty to identify and express feelings. Yet, scarce data is available regarding the vulnerability in child victims of sexual abuse to develop alexithymia. The current study aimed to compare level of alexithymia among a sample of school-aged victims of child sexual abuse (CSA) and a comparison group of non-victimized children. Results also investigated the mediational role of alexithymia in the association between CSA and both internalized and externalized behavior problems. The sample involved 429 sexually abused and 98 non-abused children aged 6 to 12 years old and their parents. The Children's Alexithymia Measure (Way et al., 2010) and the Child Behavior Checklist (Achenbach and Rescorla, 2001) were completed by parents. Clinicians filled out an adapted version of the History of Victimization Form to assess CSA characteristics (Hébert and Cyr, 2010). Analyses revealed that victims of CSA presented significantly higher levels of alexithymia compared to their non-abused counterparts. Results also highlighted the role of alexithymia mediating the association between CSA and both internalized and externalized behavior problems. Focussing on alexithymia is a promising avenue to sustain resilience and prevent further difficulties in sexually abused children.

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.

The Impact of Alexithymia on Treatment Response in Psychiatric Disorders: A Systematic Review

Treatment of psychiatric disorders relies heavily on a trial and error approach, often prolonging the time required to obtain symptomatic improvements. The identification of reliable predictors of treatment response is instrumental to enact an individualized approach. Alexithymia represents a personality trait reflecting an intrinsic difficulty in recognizing the emotional components of subjective experiences. Thus, its modulating role on treatment outcome has gathered substantial attention during the past years. In the present paper, we aimed at exploring the available evidence for Alexithymia role in influencing the treatment outcome on a wide range of psychiatric conditions by means of a systematic review.

DATA SOURCE

We performed a systematic review in Medline and Scopus, augmented by tracking the reference list of the pertinent articles.

INCLUSION CRITERIA

To be included in this review, research studies had to assess alexithymia impact on a treatment intervention delivered to manage a primary psychiatric disorder.

STUDY EVALUATION AND DATA SYNTHESIS

After removing duplicates, titles were screened first, then abstracts, and last full texts were read, eventually leading to the inclusion or exclusion of the papers according to the criteria established before the online search. Then results of the search were downloaded in.xml format and uploaded in Rayyan, a free web software, that helps expedite the initial screening of abstracts and titles using a process of semi-automation while incorporating a high level of usability. After uploading, screening of the literature was performed in blind by two investigators. Disagreement between reviewers was resolved by joint discussion with a third senior investigator. The quality of evidence was assessed using the Newcastle Ottawa Scale. Thereafter, the data considered relevant was extracted and synthetized in this paper.

RESULTS

Our search yielded a total of 30 articles dealing with a wide range of psychiatric conditions and exploring both pharmacological and psychotherapeutic interventions. Several lines of evidence suggest a complex role for alexithymia in influencing the psychiatric treatment outcome, further underscoring the need for additional research in this area to better address the existing knowledge gaps.

Impact of Alexithymia on Organ Transplant Candidates' Quality of Life: The Mediating Role of Depressive Symptoms

Solid organ transplant candidates who display alexithymia tend to report psychological distress with some displaying symptoms associated with depression which in turn has a negative impact on their quality of life. This study sought to examine the mediating role of depression on the relationship between alexithymia and physical and psychological quality of life. The sample comprised 707 patients who were under consideration for solid organ transplantation. Mediation models were used to examine the proposed hypotheses, specifically that alexithymia would predict quality of life, and that depression would mediate the relationship between alexithymia and physical and psychological quality of life. Findings revealed that alexithymia predicted both physical and psychological quality of life. Depression scores partially mediated the relationship between alexithymia and both physical and psychological quality of life. Transplant candidates with higher levels of alexithymia who report poor physical and psychological quality of life may be at increased risk for depression. Results highlight the need to assess alexithymia within this unique patient population, who may understate symptoms of depression due to attempts at positive impression management.

Influence of Selected Biomarkers on Stress and Alexithymia in Patients Under Hemodialysis Treatment

Background

Hemodialysis treatment and the high stress brought about by the treatment are the circumstances which set the background for alexithymia. Alexithymic feelings basically emerge as restriction in the world of emotion and thought, and the inability to recognize physiological changes. Biomarkers that are indicators of physical change are influential in the stress lives of individuals. This research was carried out to discover the relationships between, and to determine the influence of urea, creatinine, sodium, potassium, hemoglobin, hematocrit, albumin, calcium, phosphorus and C-reactive protein biomarkers on stress and alexithymia in individuals, who are diagnosed with chronic renal failure and receive hemodialysis treatment.

Methods

The research environment was formed of patients who underwent hemodialysis treatment in a hospital in Turkey. The subject group was comprised of 72 individuals. Demographic data form, biomarker list form, Hemodialysis Stressor Scale and Toronto Alexithymia Scale were used in the research.

Results

It was found that the levels of perceived stress of individuals who participated in the research were high at all dimensions, and 59.7% were alexithymic. The means of the total scale scores of all patients were calculated as 87.81 ± 13.59 for Hemodialysis Stressor Scale and 62.46 ± 9.84 for Toronto Alexithymia Scale. The relationship between the Toronto Alexithymia Scale and Hemodialysis Stressor Scale and selected biomarkers were determined (P < 0.05).

Conclusion

It was concluded that stress and alexithymic feelings were high in patients who received hemodialysis treatment, and that there is a relationship between C-reactive protein, creatinine, sodium, hemoglobin, hematocrit, potassium from the biomarkers and the scales and scale sub-dimensions. It is necessary to increase the awareness of nurses on the importance of the skills to communicate with individuals who have to cope with stress, manage emotions, and have high stress and emotional deprivation.

Effects of Therapeutic Alliance and Metacognition on Outcome in a Brief Psychological Treatment for Borderline Personality Disorder

Objective: The therapeutic alliance is possibly a crucial factor in treatment for borderline personality disorder (BPD). Among predictors of therapeutic alliance, aspects that have not yet been considered are metacognition or the patient's capacity to be aware of mental states. We therefore explored whether metacognition predicted alliance and if metacognition and therapeutic alliance together predicted outcome in brief treatment for BPD. Method: In a secondary analysis of a randomized controlled trial, we included N = 36 patients with BPD in the current study. The original trial assessed the effects of a 10 session psychiatric standard treatment with or without the added the Plan Analysis and the Motive Oriented Therapeutic Relationship. We assessed the therapeutic alliance session by session (Working Alliance Inventory), metacognition at session 1 (using the Metacognitive Assessment Scale-Revised) and outcome (using residual gains on the Outcome Questionnaire-45.2 between sessions 1 and 10). Results: A more differentiated capacity to understand the mind of the others at treatment onset predicted an increase of therapist-rated alliance over time. Therapist rated alliance was the only significant outcome predictor (B = -0.85, R Squared = .12). Conclusions: More differentiated metacognition predicted therapeutic alliance which in turn affected outcome, thus making metacognition a relevant therapy target early in therapy for BPD. Future studies should expand this investigation to patients with better functioning, treated with different modalities and with longer treatments.

Body talk: Sex differences in the influence of alexithymia on physical complaints among psychiatric outpatients

This study investigated the relationship between alexithymia and physical complaints among psychiatric outpatients, and whether sex moderated this relationship. Participants (N = 185) completed measures of physical complaints (bodily symptom burden, pain severity, pain interference), alexithymia, current symptom (depression, anxiety) distress, and somatosensory amplification (i.e., a person's tendency to be bothered by physical sensations). Hierarchical regression analyses were conducted, controlling for the influence of current psychiatric symptom distress and somatosensory amplification. Findings revealed differential relationships between alexithymia and physical complaints (pain interference) for women and men, in addition to main effects for sex and alexithymia. The findings suggest that the negative influence of alexithymia on bodily-related problems may not be universal.

Alexithymia as a mediator of the relationship between child sexual abuse and psychological distress in adolescence: A short-term longitudinal study

BACKGROUND

Understanding factors influencing mental health of sexually abused teenagers is essential to orient treatment with this vulnerable population. The purpose of this study was to explore alexithymia as a mediator of the relationship between child sexual abuse and psychological distress using a representative sample of teenagers, while considering gender as a potential moderator.

METHODS

Teenagers participating in the Quebec Youths' Romantic Relationships Survey completed measures evaluating a history of child sexual abuse and alexithymia at baseline while psychological distress was evaluated 6 months later.

RESULTS

A moderated mediated model revealed a partial mediation effect of alexithymia in the relationship between child sexual abuse and psychological distress. Gender acted as a moderator as the conditional indirect effects of child sexual abuse on mental health via alexithymia were stronger for boys.

CONCLUSION

Findings underscore the relevance of assessing and targeting sexually abused victims' capacity to identify and communicate emotions to promote well-being.

Moderating Effects of Alexithymia on Associations between the Therapeutic Alliance and the Outcome of Brief Psychodynamic-Interpersonal Psychotherapy for Multisomatoform Disorder

This secondary analysis of a trial on brief psychodynamic-interpersonal therapy (PIT) for patients with multisomatoform disorder investigated whether alexithymia moderates the associations between the therapeutic alliance and the outcome of PIT and whether moderating effects of alexithymia remain significant when controlling for depression. Eighty-three patients with multisomatoform disorder receiving PIT were statistically analyzed. Moderation analyses were performed with the SPSS macro PROCESS. The primary outcome (Y), self-reported physical quality of life at 9-month after the end of PIT, was measured with the physical component summary (PCS) of the SF-36 Health Survey. The potential moderator (M) alexithymia was operationalized with the Toronto Alexithymia Scale (TAS-20) at pre-treatment and the predictor (X) the therapeutic alliance was rated by both patients and therapists via the Helping Alliance Questionnaire (HAQ) at the end of PIT. Moreover, the PCS at pre-treatment functioned as covariate in all moderation models. When the patients' alliance ratings were analyzed, alexithymia did not moderate associations between the alliance and the outcome. When the therapists' alliance ratings were evaluated, alexithymia moderated the relationship between the alliance and the outcome (p < 0.05): a stronger alliance in the therapists' perspective was beneficial for the outcome only for patients scoring above 61 on the TAS-20. This moderating effect of alexithymia was, however, not statistically significant anymore when adding the pre-treatment depression scores (PHQ-9) as a covariate to the moderation model. The results underline the importance of a good therapists' view of the alliance when treating alexithymic patients and highlight the complex interaction between alexithymia and depression. Future studies are needed to extend the scope of research regarding which psychotherapeutic mechanisms of change are beneficial for which patients.
