Abstract
Introduction: Emotional dysregulation is estimated to affect between 30% and 70% of individuals with ADHD, regardless of the presence of comorbid psychiatric disorders. The present study aimed to compare adaptive and maladaptive emotion regulation strategies, symptoms of anxiety and depression, and borderline personality disorder traits in adults with and without ADHD. Additionally, the interrelationships among these variables were examined. Material and Methods: A total of 216 adults with ADHD (M = 33.13, SD = 8.40) and 215 individuals in the control group (M = 34.18, SD = 10.10), aged between 18 and 65 years, completed the following questionnaires: the Adult ADHD Self-Report Scale v1.1 (ASRS), the Cognitive Emotion Regulation Questionnaire (CERQ), the Emotion Regulation Questionnaire (ERQ), the Hospital Anxiety and Depression Scale (HADS), and The BPD Checklist. Relationships between variables were analysed using independent-samples t-tests, correlation analyses, and linear regression models. Results: Participants with ADHD reported significantly more frequent use of maladaptive emotion regulation strategies, particularly self-blame and rumination, compared with the control group. The clinical group also exhibited higher levels of anxiety, depression, and borderline personality disorder traits than the control group. Regression analyses demonstrated that both adaptive and maladaptive emotion regulation strategies significantly predicted the severity of anxiety and depressive symptoms, as well as borderline personality disorder traits. Conclusions: The findings highlight the importance of emotion regulation and co-occurring psychopathological symptoms in the adult ADHD population.
