RESUMEN
The goal of this work was to explore associations of constituent factors of alexithymia on mental health and potential mediating effects of emotion regulation strategies, specifically suppression and reappraisal. Data were collected through the crowd-sourcing platform Amazon Mechanical Turk (MTURK). Three hundred seventy-seven individuals completed questionnaires related to distress (Depression Anxiety Stress Scales [DASS]), emotion regulation (Emotion Regulation Questionnaire [ERQ]) and Alexithymia (Bermond-Vorst Alexithymia Questionnaire [BVAQ]). Three mediation models were constructed for depression, anxiety and stress, with BVAQ subscales (verbalizing, identifying, emotionalizing, fantasizing, and analyzing) as predictors and ERQ subscales (suppression and reappraisal) as mediators. Results indicated 37.3 % variance in depression, 25.2 % variance in anxiety, and 35.3 % variance in stress was explained by each model. Direct associations revealed emotionalizing and fantasizing were negatively associated with depression, anxiety, and stress, while verbalizing was additionally associated with depression, identifying was additionally associated with anxiety, and all four BVAQ subscales were associated with stress. BVAQ subscales demonstrated negative associations with reappraisal and positive associations with suppression that mediated anxiety and depression. However, suppression did not mediate relationships between BVAQ subscales with stress. Findings support the importance of examining multiple factors of alexithymia and associations with emotion regulation strategies and distress.
