BACKGROUND: Alexithymia, characterized by difficulty identifying and expressing emotions, is often associated with various psychiatric disorders, including personality disorders (PDs). This study aimed to explore the relationship between alexithymia and PD, focusing on their common origins and implications for treatment.
METHODS: A systematic review was conducted following PRISMA guidelines using databases such as MEDLINE (PubMed), Scopus, and Web of Science. The inclusion criteria were studies assessing adults with DSM-5-diagnosed personality disorders using validated alexithymia scales. The Newcastle‒Ottawa Scale was used to assess the quality of the included studies.
RESULTS: From an initial yield of 2434 citations, 20 peer-reviewed articles met the inclusion criteria. The findings indicate a significant association between alexithymia and personality disorders, particularly within Clusters B and C. Patients with these disorders exhibited higher levels of alexithymia, which correlated with increased emotional dysregulation and interpersonal difficulties. The review also highlighted the comorbidity burden of conditions such as psychosomatic disorders, eating disorders, depression, anxiety, suicidal behavior, and substance use disorders.
CONCLUSIONS: These findings underscore the need for integrating alexithymia-focused assessments into clinical practice to enhance therapeutic approaches, allowing for more personalized and effective interventions. Addressing the emotional processing challenges in patients with personality disorders could significantly improve patient outcomes. Future research should prioritize establishing clinical guidelines and conducting longitudinal studies to explore the relationship between alexithymia and specific personality disorder subtypes, ensuring the practical translation of these findings into clinical practice.
