Alexithymia and aspects of dreaming: Differential associations of alexithymia facets with dream variables.

Research on aspects of dreaming associated with alexithymia has yielded mixed results. The present study recruited a young adult online sample of 577 participants who completed validated indices of alexithymia, emotion suppression, negative moods, and eight aspects of dreaming, with a focus on evaluating a counterintuitive previous finding that alexithymia and two of its core facets were associated with greater self-reported typical emotional intensity of dreams. Total alexithymia and facet scores showed differential relationships to aspects of dreaming including dream recall frequency, emotionality, meaningfulness, nightmare frequency, nightmare distress, usefulness of dreams in problem-solving and creativity, and learning about oneself through dreams. Planned hierarchical regression controlling for demographics, alcohol use, and dream recall frequency indicated that the difficulties identifying feelings (DIF) facet of alexithymia was a significant positive predictor of dream emotionality, whereas the externally oriented thinking (EOT) facet was a significant negative predictor. Stress, but not emotion suppression, mediated the positive relationship between DIF and dream emotionality. The likely role of dream emotionality in higher ratings of nightmare distress, dream meaningfulness, and learning about oneself through dreams among those with higher DIF scores is noted, along with other findings and the strengths and limitations of the study.

Adult symptoms of ASD in relation to excessive internet use: The roles of ADHD symptoms and negative mood.

Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) have been reportedly associated with excessive internet use, also known as internet addiction. As ADHD is the most common comorbidity in ASD, the present study examined the possibility that ADHD symptoms, and/or trait and mood factors linked to ASD, ADHD and internet addiction, could account for the association of ASD with internet addiction symptoms. A nonclinical young adult sample of 248 internet using men and women completed self-report measures of ASD and ADHD symptoms, alexithymia, impulsivity, negative moods and internet addiction symptoms. Scores on the ASD and ADHD symptom measures were normally distributed, consistent with the notion that the corresponding disorders represent extreme, impairing ends of population distributions of their symptoms. Hierarchical regression followed by path analysis indicated that the relationship between ASD and internet addiction symptoms was fully mediated by ADHD symptoms and negative moods. Further, the relationship between ADHD and internet addiction symptoms was partially mediated by impulsivity and negative moods. Present findings point to the mediating roles of ADHD symptoms and negative moods in the association of ASD with internet addiction symptoms.

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.

Influence of social interactions, professional supports and fear of death on adults' preferences for life-sustaining treatments and palliative care.

AIM: To explore the significance of culture, professional support in the community, social interactions and intrapersonal determinants of adults' preferences for life-sustaining treatments and palliative care. METHODS: A cross-sectional design with a Social Ecological Model was used. Between 1 October 2012 and 31 December 2012, 474 adults aged ≥20 years living in a city of Southern Taiwan completed the survey. Data were analysed using hierarchical multiple regression. RESULTS: The life-sustaining measures model was significant with 15.3% (p < 0.0001) of the variance in the Modified Emmanuel Medical Directives being explained by variables of death of self and healthcare services' support. The palliative care model was significant with 18% (p < 0.0001) of the variance in the Modified Hospice Attitude Scale being explained by variables of palliative care knowledge, death of self and social interactions. However, cultural value adherence did not predict adults' preferences for life-sustaining measures and community resources support did not predict palliative care preference. CONCLUSIONS: Findings enhance our understanding of the significance of different societal levels on adults' preferences for end-of-life care. Palliative care knowledge, fear of death, healthcare services' support and social interactions are essential factors that need to be taken into consideration when it comes to discussion about life-sustaining treatments and palliative care.

Alexithymia, narcissism and social anxiety in relation to social media and internet addiction symptoms.

There has been considerable interest in trait correlates of excessive or problematic use of the internet, known as internet addiction. However, the concept of internet addiction has been criticised as too broad. Specific forms of excessive internet use, for example, social media, may have different trait correlates compared to internet use in general. The present study compared levels of internet and social media addiction symptoms in relation to three traits previously linked to one or the other form of excessive behaviour: alexithymia, narcissism and social anxiety. There were 217 young adult social media- and internet-using participants aged 18-35 years recruited from two university campuses in southeast Queensland, Australia. They completed an online questionnaire battery that included a demographics questionnaire and widely used, validated measures of narcissism, alexithymia and social anxiety. Hierarchical regressions indicated that after controlling for demographic variables, internet addiction symptoms were predicted by social anxiety, narcissism and alexithymia, whereas social media addiction symptoms were predicted only by social anxiety and narcissism. Results suggest that the association of alexithymia with internet addiction symptoms does not encompass excessive use of social media, and support the contention that the concept of internet addiction may be too broad.

Alexithymia, reward sensitivity and excessive exercise in non-binge-eaters versus severe binge eaters: Implications for primary and secondary exercise dependence.

A distinction has been made between primary and secondary exercise dependence, with the latter defined as excessive exercise secondary to disordered eating and weight concerns. Based on theoretical considerations from research on the roles of trait factors in addictions, the present study used validated scales to assess alexithymia, sensitivity to reward and punishment, emotion regulation and interoception in relation to exercise dependence symptoms in Australian male and female non-binge eaters (n = 228) and severe binge eaters (n = 126) aged 18-30 yr. In both groups, exercise dependence symptoms were significantly positively associated with reward sensitivity and interoceptive awareness, with the latter two variables predicting exercise dependence symptoms in hierarchical regression models; punishment sensitivity was significantly negatively related to such symptoms. Alexithymia was significantly associated with exercise dependence symptoms only in non-binge eaters; in severe binge eaters, alexithymia explained 0% of unique variance. Male sex was associated with more exercise dependence symptoms in severe binge eaters only. Participants in the severe binge group scored significantly higher on measures of exercise dependence, alexithymia, risky alcohol use, and sensitivity to reward and punishment, and significantly lower on emotion regulation, compared to those in the non-binge group. Hierarchical regression models explained 25% of variance in exercise dependence symptoms in non-binge-eaters and 43% in severe binge eaters. Findings are discussed in terms of the distinction between primary and secondary exercise dependence, the role of alexithymia, study limitations including data collection during the COVID-19 pandemic in Australia, and suggestions for future research.

Is it the Taste or the Buzz? Alexithymia, Caffeine, and Emotional Eating.

BACKGROUND: Alexithymia, a relatively stable personality trait characterized by difficulties identifying and describing feelings and externally oriented thinking, has been linked to both substance use disorders and eating disorders. In nonclinical samples, alexithymia is associated with heavier consumption of alcohol and caffeine. Both are psychoactive drugs, but unlike most drugs they are typically consumed in the context of palatable and calorie-rich products. OBJECTIVES: Given the association of alexithymia with disordered eating, the present study evaluated the hypothesis that heavier consumption of caffeine by those with high levels of alexithymia may be motivated by the palatable and caloric aspects of common caffeine products rather than by drug-seeking. METHODS: There were 224 participants aged 17-63 years who completed instruments assessing demographics, alexithymia, emotional eating, caffeine consumption, alcohol consumption, negative moods, and reward sensitivity. RESULTS: As predicted, alexithymia was positively related to emotional eating as well as consumption of caffeine and alcohol, and alexithymia was a significant predictor of caffeine intake in regression models. However, there was no indication of mediation by emotional eating. CONCLUSIONS: Alexithymia is characterized by deficient emotion regulation and negative moods, hence use of drugs and/or foods to regulate emotions, combined with poor interoceptive awareness, may account for excessive consumption of drugs or foods as alternative emotion regulation strategies in those with high levels of this trait.

Alexithymia, Impulsivity, and Reward Sensitivity in Young Adult University Student Children of Alcoholics.

BACKGROUND AND OBJECTIVES: Personality traits previously known as risk factors for alcohol use disorder (AUD) were assessed in 29 young adult children of alcoholics (COAs) and 68 young adult children of nonalcoholics (non-COAs). Male and female university students (Mage = 22.11 years) completed questions pertaining to demographics and alcohol use, and the Children of Alcoholics Screening Test; Toronto Alexithymia Scale; Barratt Impulsiveness Scale; Sensitivity to Punishment and Sensitivity to Reward Questionnaire; and Depression Anxiety Stress Scales. RESULTS: Results indicated that personality traits of alexithymia, reward sensitivity, and impulsivity, as well as negative moods, were significantly elevated in COAs compared to non-COAs, independent of current alcohol consumption and drinking history. CONCLUSIONS: Findings are consistent with familial transmission of AUD-associated personality traits in COAs, presumably via influences of genetics and/or familial environment.

Alexithymia and Alcohol Dependence: The Roles of Negative Mood and Alcohol Craving.

Background: Alexithymia is a personality trait associated with emotion regulation difficulties. Up to 67% of alcohol-dependent patients in treatment have alexithymia. Objectives: The objective of this study was to investigate the direct and indirect effects of alexithymia, negative mood (stress, anxiety, and depression) and alcohol craving on alcohol dependence severity. Methods: Three hundred and fifty-five outpatients (mean age = 38.70, SD = 11.00, 244 males, range 18-71 years) undergoing Cognitive-Behavioral Therapy for alcohol dependence completed the Toronto Alexithymia Scale (TAS-20), Depression Anxiety Stress Scales (DASS-21), Obsessive Compulsive Drinking Scale (OCDS), and Alcohol Use Disorders Identification Test (AUDIT) prior to the first treatment session. Results: Alexithymia had an indirect effect on alcohol dependence severity, via both negative mood and alcohol craving (b = 0.03, seb = 0.008, 95% CI: 0.02-0.05). An indirect effect of negative mood on alcohol dependence via alcohol craving was also observed (b = 0.12, seb = 0.03, 95% CI: 0.07-0.16). Conclusions/importance: Alexithymia worked through negative mood and alcohol craving leading to increased alcohol dependence severity, indicating that craving had an indirect effect on the relationship between alexithymia and alcohol dependence severity. Targeting alcohol craving and negative mood for alcohol-dependent patients with alexithymia seems warranted.

Parental bonding, adult attachment, and theory of mind: A developmental model of alexithymia and alcohol-related risk.

OBJECTIVE: A developmental model of alexithymia in relation to alcohol-related risk was examined. METHOD: Validated indices of parental bonding, adult attachment, alexithymia, theory of mind (ToM), alcohol-related risk, and mood were administered to a nonclinical sample of 286 alcohol-using men and women. RESULTS: Hierarchical regression incorporating demographic and psychosocial variables accounted for 44% of the variance in alexithymia. Modeling indicated a significant path from dysfunctional maternal bonding to insecure adult attachment to alexithymia to risky drinking; a separate path indicated an indirect effect of alexithymia in association between the deficient ToM and risky drinking. CONCLUSIONS: Findings were consistent with a developmental model where dysfunctional parental bonding in childhood manifests in adulthood as insecure attachment and alexithymia, the latter reflecting the insufficient acquisition of emotion regulation skills; alexithymia, in turn, increases the risk of problematic drinking as an emotion regulation strategy.

Alexithymia and Mood: Recognition of Emotion in Self and Others.

The present study explored relationships between alexithymia-a trait characterized by difficulties identifying and describing feelings and an external thinking style-and negative moods, negative mood regulation expectancies, facial recognition of emotions, emotional empathy, and alcohol consumption. The sample consisted of 102 university (primarily psychology) students (13 men, 89 women) aged 18 to 50 years (M = 22.18 years). Participants completed the Toronto Alexithymia Scale (TAS-20), Negative Mood Regulation Scale (NMRS), Depression Anxiety Stress Scales (DASS-21), Reading the Mind in the Eyes Test (RMET), Interpersonal Reactivity Index (IRI), and Alcohol Use Disorders Identification Test (AUDIT). Results were consistent with previous findings of positive relationships of TAS-20 alexithymia scores with both alcohol use (AUDIT) and negative moods (DASS-21) and a negative relationship with emotional self-regulation as indexed by NMRS. Predicted negative associations of both overall TAS-20 alexithymia scores and the externally oriented thinking (EOT) subscale of the TAS-20 with both RMET facial recognition of emotions and the empathic concern (EC) subscale of the IRI were supported. The mood self-regulation index NMRS fully mediated the relationship between alexithymia and negative moods. Hierarchical linear regressions revealed that, after other relevant variables were controlled for, the EOT subscale of the TAS-20 predicted RMET and EC. The concrete thinking or EDT facet of alexithymia thus appears to be associated with diminished facial recognition of emotions and reduced emotional empathy. The negative moods associated with alexithymia appear to be linked to subjective difficulties in self-regulation of emotions.

Caffeine use and alexithymia in university students.

Abstract Alexithymia refers to difficulties with identifying, describing, and regulating one's own emotions. This trait dimension has been linked to risky or harmful use of alcohol and illicit drugs; however, the most widely used psychoactive drug in the world, caffeine, has not been examined previously in relation to alexithymia. The present study assessed 106 male and female university students aged 18-30 years on their caffeine use in relation to several traits, including alexithymia. The 18 participants defined as alexithymic based on their Toronto Alexithymia Scale (TAS-20) scores reported consuming nearly twice as much caffeine per day as did non-alexithymic or borderline alexithymic participants. They also scored significantly higher than controls on indices of frontal lobe dysfunction as well as anxiety symptoms and sensitivity to punishment. In a hierarchical linear regression model, sensitivity to punishment negatively predicted daily caffeine intake, suggesting caffeine avoidance by trait-anxious individuals. Surprisingly, however, TAS-20 alexithymia scores positively predicted caffeine consumption. Possible reasons for the positive relationship between caffeine use and alexithymia are discussed, concluding that this outcome is tentatively consistent with the hypo-arousal model of alexithymia.

Adult symptoms of ASD and ADHD in relation to alcohol use: Potential roles of transdiagnostic features.

Attention Deficit Hyperactivity Disorder (ADHD) is the most common comorbidity in Autism Spectrum Disorder (ASD). ADHD is a risk factor for alcohol misuse whereas ASD is often regarded as protective; however, research on ASD and alcohol use has yielded conflicting findings, sometimes implicating the role of comorbid ADHD. The possibility that certain transdiagnostic features (i.e., characteristics associated with multiple disorders) may underlie relationships of both disorders to alcohol use in adults was examined in the present study. A nonclinical young adult sample of 248 alcohol users (117 men, 131 women) completed validated self-report measures of ASD and ADHD symptoms as well as the transdiagnostic features alexithymia, impulsivity, and negative moods. ASD and ADHD symptoms were normally distributed, suggesting that the respective disorders represent extreme, dysfunctional ends of population distributions of symptoms. Path analysis indicated that the significant positive association between ASD and ADHD symptom measures was fully mediated by alexithymia, impulsivity, and negative moods. Hierarchical regression and path analysis indicated that the positive relationship between ADHD symptoms and alcohol use severity was fully mediated by transdiagnostic features, particularly alexithymia and impulsivity, whereas the relationship between ASD and alcohol use severity was positively mediated by these features (especially alexithymia), with a highly significant and negative direct effect. Present findings may help reconcile previous conflicting evidence on the relationship of ASD to alcohol use, and the role of comorbid ADHD, by emphasizing the roles of alexithymia and impulsivity in both ASD and ADHD as transdiagnostic traits promoting excessive drinking.

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.

Alexithymia and Alcohol Use: Evaluating the Role of Interoceptive Sensibility with the Revised Multidimensional Assessment of Interoceptive Awareness.

Alexithymia has been linked to risky or problematic alcohol use, with a common interpretation invoking deficient emotion regulation and use of alcohol to cope with distress. An alternative explanation positing a general deficit of interoception in alexithymia suggested that poor awareness of internal cues of overconsumption may promote excessive drinking. The present study assessed predictions based on these hypotheses in 337 young adult alcohol users recruited online. Participants completed validated questionnaire indices of alcohol use, alexithymia, emotion regulation, interoceptive sensibility, and sensitivity to reward and punishment. Alcohol use was positively correlated with alexithymia and reward sensitivity, and negatively correlated with emotion regulation as expected, but was uncorrelated with interoceptive sensibility. Alexithymia was not significantly correlated with most dimensions of interoceptive sensibility but was highly negatively correlated with emotion regulation. Hierarchical regression controlling for demographic variables indicated that alexithymia, emotion regulation, sex, and sensitivity to reward and punishment were significant predictors of alcohol use levels. Bootstrapped mediation test controlling for all other variables indicated mediation of the association between alexithymia and alcohol use by deficient emotion regulation but not interoceptive sensibility. Results supported the emotion regulation deficit interpretation of the association of alexithymia with alcohol use. Limitations concerning interoception measurement, online samples, self-report measures, cross-sectional designs, and collection of data during the COVID-19 pandemic are discussed. Future research could follow up on these findings by testing interoceptive accuracy in addition to interoceptive sensibility in relation to alexithymia and alcohol use.

Adults' perspectives of experiences and preferences for end-of-life care.

BACKGROUND: Decisions about end-of-life care often raise clinical and ethical challenges, especially when the person's capacity to contribute in the decision making at the end of life is limited. AIM: This study aimed to explore Taiwanese adults' preferences associated with communication, healthcare planning, life-sustaining treatments and palliative care and experiences of end-of-life care. METHODS: Semi-structured interviews were conducted with 16 adults aged 20 years and above. The sampling approach was a convenience strategy in a community centre located in a metropolitan area in the Southern region of Taiwan. A qualitative content analysis approach was used to elicit key themes from the data. RESULTS: Significant findings related to the two main themes of adults' experiences, including the observed distress of those who were dying and the distress experienced by the family. Other key findings pertain to personal preferences for end-of-life care, such as preferred end-of-life communication, preparing for the end-of-life and maintenance of quality of life. CONCLUSIONS: This exploratory study offers insight into 16 Taiwanese community-dwelling adults' views of preferences regarding end-of-life communication, preparation for the end of life and maintenance of quality of life, as well as their experiences of end-of-life care. A further exploration is suggested to elicit how personal end-of-life experiences shape individuals' health practices in advance care planning for end-of-life care.

An Exploration of Psychological Resilience among Undergraduate Nursing Students Undertaking an Adult Nursing Virtual Practicum during the Coronavirus Pandemic in Taiwan: A Qualitative Study.

This qualitative study aimed to explore the psychological resilience of undergraduate nursing students partaking in a virtual practicum during the coronavirus pandemic (COVID-19) in Taiwan. The virtual practicum, a form of online learning, creates challenges compared to the traditional teaching-learning experience of an actual clinical placement. Exploring how students overcome learning difficulties and build resilience is necessary for a new learning environment or for future online learning. Constructivist grounded theory and the Standards for Reporting Qualitative Research checklist were followed. Purposive and theoretical sampling were used to recruit 18 student nurses for data saturation. Semi-structured, face-to-face interviews were conducted individually to collect data. Initial, focused, and theoretical coding and constant comparative data analysis were performed. Credibility, originality, resonance, and usefulness guided the assessment of the study's quality. The core category of psychological resilience in the virtual practicum was constructed to reflect Taiwanese nursing students' progress and experiences of learning during the virtual practicum. This core category consisted of three subcategories: (i) learning difficulties within one's inner self; (ii) staying positive and confident; and (iii) knowing what is possible. The findings identified psychological resilience as an important factor for students to adjust to the adverse experiences of a rapidly changing learning environment, such as the virtual practicum. The substantive theory of psychological resilience provided a frame of reference for coping with possible future difficulties. Correspondingly, psychological resilience reflected individuals' potential characteristics and may help students to enter and remain in the nursing profession.

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

Confirmatory factor analyses were conducted to evaluate the factorial validity of the Toronto Alexithymia Scale in an alcohol-dependent sample. Several factor models were examined, but all models were rejected given their poor fit. A revision of the TAS-20 in alcohol-dependent populations may be needed.

The Influence of Alexithymia on Alcohol Craving, Health-Related Quality of Life and Gender in Alcohol-Dependent Outpatients.

Alexithymia is a vulnerability factor for physical and mental illness that can significantly influence the daily function of alcohol-dependent patients. The aim of this study was to examine the indirect effect of obsessive thoughts and compulsive behaviors involving alcohol craving on the relationship between alexithymia, quality of life (QoL) of psychological well-being and health status. Three hundred and eighty-one outpatients (263 males and 118 females) in treatment for alcohol dependence completed self-report measures of alexithymia, alcohol craving, GHQ-28 (QoL-psychological well-being) and SF-36 (QoL-health status). Males scored significantly higher than females on aspects of alexithymia, and females reported significantly higher levels of alcohol craving. Path analysis showed an indirect effect of alcohol craving on the relationship between alexithymia, QoL-psychological well-being and self-reported QoL-health status for males only. The current study provides important new information about impaired self-reported health status and well-being among male alcohol-dependent treatment seekers with alexithymia.

Social Interaction Anxiety, Alexithymia, and Drinking Motives in Australian University Students.

In young adults at university, social interaction anxiety has been linked to elevated risk of alcohol-related problems, as has alexithymia. The present study sought to assess whether social interaction anxiety is, like alexithymia, associated with the primary motive of drinking to cope with negative affect. There were 126 undergraduates (76 females, 50 males), aged 18-25 years, who were recruited from two southeast Queensland universities to complete validated self-report measures of problematic drinking, alexithymia, drinking motives, and social interaction anxiety. As predicted, social interaction anxiety was positively related to problematic drinking and coping motives for drinking. Alexithymia mediated the relationship of social interaction anxiety with coping motives. Findings were consistent with a developmental hypothesis of the links between social anxiety, alexithymia, and drinking motives. Given the cross-sectional design of the current study, longitudinal research is ultimately needed to confirm such interpretations of alexithymia and alcohol use among socially anxious young adults at university.
