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

The role of personality traits in mediating the relation between fear of negative evaluation and social interaction anxiety

Introduction

Social interaction anxiety and fear of negative evaluation have many maladaptive outcomes and, in order to counteract their effects, it is essential to identify those psychological or social factors that make people vulnerable to them. One of these factors is the individual's personality structure: some personality traits increase the individuals' vulnerability to symptoms of social anxiety, while others protect them.

Methods

The aim of this paper is to analyse the role of HEXACO personality traits in mediating the relationship between fear of negative evaluation and social anxiety, in a sample of 352 cadets from the Land Forces Academy of Sibiu. The relationships between these concepts were analysed using structural equation modeling (SEM) in several hypothetical models, two of which were ultimately validated.

Results

In the first model, the fear of negative evaluation has an indirect effect on social interaction anxiety through the mediation of extraversion, conscientiousness, and altruism, separately. Furthermore, extraversion, conscientiousness, and altruism play a serial mediating role in the association between the fear of negative evaluation and social interaction anxiety. In the second model, the fear of negative evaluation has an indirect effect on social interaction anxiety through the mediation of social boldness, liveliness, and organization, separately, but not through altruism. Social boldness, liveliness, and organization played a serial mediating role in the relationship between the two constructs, while altruism moderated the relationship between liveliness, organization, and social interaction anxiety.

Discussion

Analysing the relationship between the individuals' personality traits, social anxiety, and fear of negative evaluation facilitated the identification of ways to cultivate desirable behaviours in social environments typified by compliance, discipline, uniformity, and rigor.

The Association between Alexithymia and Social Media Addiction: Exploring the Role of Dysmorphic Symptoms, Symptoms Interference, and Self-Esteem, Controlling for Age and Gender

Given the popularity of social media and the growing presence of these tools in the daily lives of individuals, research about the elements that can be linked to their problematic use appears to be of great importance. The objective of this study was to investigate the factors that may contribute to the levels of social media addiction, by focusing on the role of alexithymia, body image concern, and self-esteem, controlled for age and gender. A sample of 437 social media users (32.5% men, 67.5% women; M_age = 33.44 years, SD = 13.284) completed an online survey, including the Bergen Social Media Addiction Scale, Body Image Concern Inventory, Rosenberg Self-Esteem Scale, and Twenty-Item Toronto Alexithymia Scale, together with a demographic questionnaire. Results showed a significant association between alexithymia and social media addiction, with the total mediation of body image concern (and more in detail, body dissatisfaction) and the significant moderation of self-esteem. Gender and age showed significant effects in these relationships. Such findings may offer further insights into the field of clinical research on social media addiction and may provide useful information for effective clinical practice.

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 disrupts emotion regulation processes and is associated with greater negative affect and alcohol problems

OBJECTIVE

Alexithymia is common among people who abuse alcohol, yet the mechanisms by which alexithymia exerts its influence remain unclear. This analysis tested a model whereby the three subscales of the Toronto Alexithymia Scale exert an indirect effect on alcohol problems through difficulties with emotion regulation and psychological distress.

METHOD

Men and women (n = 141) seeking alcohol use disorder (AUD) treatment completed the Toronto Alexithymia Scale, the Difficulties with Emotion Regulation Scale, the Brief Symptom Inventory, the Short Inventory of Problems, and the Alcohol Dependence Scale.

RESULTS

The Difficulty Identifying Feelings subscale of the Toronto Alexithymia Scale was positively associated with alcohol problems through emotion dysregulation and psychological distress. The other two subscales, Difficulty Describing Feelings and Externally oriented Thinking, were not associated with any other variables.

CONCLUSION

People with alexithymia may consume alcohol to help regulate undifferentiated states of emotional arousal. Given the prevalence of alexithymia among people who abuse alcohol, treatment supplements that enhance the identification of emotions are needed.

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

BACKGROUND

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

METHOD

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

RESULTS

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

LIMITATIONS

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

CONCLUSION

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

The association between alexithymia and eating behavior in children and adolescents

OBJECTIVE

Alexithymia, or the difficulty identifying or describing one's own emotions, may be a risk factor for dysregulated eating and excess weight gain. However, the relationships between alexithymia and eating behaviors in community samples of non-clinical youth have not been well-characterized. We hypothesized that alexithymia would be positively associated with disordered and disinhibited eating in a community-based sample of boys and girls without an eating disorder.

METHOD

Two hundred children (8-17 years old) across the weight spectrum completed an interview to assess loss of control (LOC) eating and eating-related psychopathology, a laboratory test meal designed to induce disinhibited eating, and questionnaires to assess alexithymia, eating in the absence of hunger, and emotional eating. Linear and logistic regressions were conducted to examine the relationship between alexithymia and eating variables, with age, sex, race, and fat mass as covariates. Test meal analyses also adjusted for lean mass. Given the overlap between alexithymia and depression, all models were repeated with depressive symptoms as an additional covariate.

RESULTS

Alexithymia was associated with an increased likelihood of reporting LOC eating (p < .05). Moreover, alexithymia was positively associated with disordered eating attitudes, emotional eating, and eating in the absence of hunger (ps < .05). Greater alexithymia was associated with more carbohydrate and less fat intake at the test meal (ps < .05). After adjusting for depressive symptoms, alexithymia remained associated with eating in the absence of hunger and carbohydrate and fat intake (ps < .05).

DISCUSSION

In healthy children, alexithymia is associated with some facets of eating behavior and food intake. If supported prospectively, these preliminary findings suggest alexithymia may be a modifiable risk factor to reduce disordered eating and excess weight gain in youth.
