Background: Alexithymia is a multidimensional trait comprised of difficulties identifying feelings, difficulties describing feelings, and externally orientated thinking. It is regarded as an important risk factor for emotional disorders, but there are presently limited data on each specific facet of alexithymia, or the extent to which deficits in processing negative emotions, positive emotions, or both, are important. In this study, we address these gaps by using the Perth Alexithymia Questionnaire (PAQ) to comprehensively examine the relationships between alexithymia and depression, anxiety, and stress symptoms., Methods: University students (N = 1250) completed the PAQ and the Depression Anxiety Stress Scales-21. Pearson correlations, hierarchical regressions, and latent profile analysis were conducted., Results: All facets of alexithymia, across both valence domains, were significantly correlated with depression, anxiety, and stress symptoms (r = 0.27-0.40). Regression analyses indicated that the alexithymia facets, together, could account for a significant 14.6 %-16.4 % of the variance in depression, anxiety, and stress. Difficulties identifying negative feelings and difficulties identifying positive feelings were the strongest unique predictors across all symptom categories. Our latent profile analysis extracted eight profiles, comprising different combinations of alexithymia facets and psychopathology symptoms, collectively highlighting the transdiagnostic relevance of alexithymia facets., Limitations: Our study involved a student sample, and further work in clinical samples will be beneficial., Conclusions: Our data indicate that all facets of alexithymia, across both valence domains, are relevant for understanding depression, anxiety, and stress. These findings demonstrate the value of facet-level and valence-specific alexithymia assessments, informing more comprehensive understanding and more targeted treatments of emotional disorder symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2024 The Authors.

Beliefs about the controllability and usefulness of emotions may influence successful emotion regulation across multiple emotional disorders and could thus be influential mechanisms in long-term mental health outcomes. However, to date there has been little empirical work in this area. Our aim was to fill this gap, by examining the links between emotion beliefs and common emotional disorder symptoms. Specifically, we examined whether emotion beliefs can account for significant variance in depression, anxiety, and stress symptoms, and explored which profiles of emotion beliefs might characterise each of these symptom categories. A sample of 948 Australian university students completed self-report measures of emotion beliefs and emotional disorder symptoms. A path analysis indicated that emotion beliefs accounted for a modest but significant 11%, 12%, and 9% of the variance in depression, anxiety, and stress symptoms, respectively (ps <.001). A latent profile analysis revealed six different profiles of combinations of emotion beliefs and emotional disorder symptom levels, collectively reinforcing the transdiagnostic relevance of emotion beliefs across each symptom category. Overall, our results indicate the importance of considering emotion beliefs in conceptualisations of depression, anxiety, and stress, and suggest that emotion beliefs may be a useful assessment and treatment target. What is already known about this topic: Ford and Gross's (2018, 2019) theoretical framework of emotion beliefs posits that believing positive and negative emotions are uncontrollable and useless is detrimental for emotion regulation efforts and mental health outcomes. Beliefs about emotions being uncontrollable are associated with increased emotional disorder symptoms. The limited research examining beliefs about the usefulness of emotions indicates that believing emotions are useless is also associated with increased emotional disorder symptoms. What this topic adds: This study is the first to comprehensively examine controllability and usefulness beliefs across the negative and positive valence domains. We systematically mapped the emotion belief profiles characterising depression, anxiety, and stress symptoms, and found profiles with stronger maladaptive emotion beliefs tended to have greater emotional disorder symptoms. We found that both belief categories across both valence domains are relevant to emotional disorder symptoms, but beliefs about the controllability of negative emotion were particularly important.
