5. Student recognition decision No. 4058 dated December 28, 2022 of the President of the University of Social Sciences and Humanities, Vietnam National University, Hanoi.

6. Changes in the training process: Extend the training period by 6 months (12/2024 - 06/2025) according to Decision No. 6934/QD-XHNV dated December 16, 2024 of the President of the University of Social Sciences and Humanities, Vietnam National University, Hanoi.

7. Project title: Psychological therapy for a case with symptoms of schizoid personality disorder.

8. Major: Clinical Psychology; Code: 8310402

9. Scientific instructor:

- Prof. Dr. Tran Thi Minh Duc, Department of Psychology, University of Social Sciences and Humanities, Vietnam National University, Hanoi.

- Dr. Nguyen Thi Anh Thu, Department of Psychology, University of Social Sciences and Humanities, Vietnam National University, Hanoi.

10. Summary of project results:

The paper presents an overview of personality and personality disorders, focusing on conceptual issues, history, epidemiology, risk factors, impact on life functioning, clinical features, diagnostic criteria according to DSM-5-TR, ICD10, and the new ICD11 approach to schizoid personality disorder. Furthermore, the paper analyzes current therapeutic approaches to schizoid personality disorder.

The client was treated with cognitive behavioral therapy (CBT). The intervention results showed that the client had some improvements in life functions, reduced maladaptive behaviors, and increased ability to recognize negative emotions. However, maladaptive thoughts generally changed little, and the manifestations of dissociation/schizophrenia were still evident.

11. Practical application:

From theoretical issues and results obtained in clinical intervention practice, the project provides further evidence on the effectiveness as well as limitations of psychotherapy using cognitive-behavioral approach for schizoid personality disorder (not excluding the therapist's competence factors).

12. Further research directions: Clients with manifestations of schizoid personality disorder who were treated in the project revealed clear deficits in social functioning in a not too unusual family and social context, compared with theoretical views on the cause of the disorder, suggesting a physical condition, related to biological characteristics of the brain.

13. Published works related to the project: none.

11. Summary of the findings of the project:

The project presents an overview of personality and personality disorders, focusing on conceptual issues, history, epidemiology, risk factors, impacts on life functioning, clinical characteristics, diagnostic criteria according to DSM-5-TR and ICD-10, as well as the new ICD-11 approach to schizoid personality disorder. Furthermore, the project analyzes current therapeutic approaches for schizotypal personality disorder.

The client was treated using a cognitive-behavioral therapy (CBT) approach. The intervention results showed some improvement in the client's life functioning, a reduction in maladaptive behaviors, and an increased ability to identify negative emotions. However, maladaptive thoughts generally remain unchanged, and detachment/schizoid manifestations remain prominent.

12. Practical applicability, if any:

Based on theoretical issues and the results obtained from clinical intervention practice, the project provides additional evidence on the effectiveness as well as the limitations of cognitive-behavioral therapy (CBT) for schzoid personality disorder (without excluding therapist competency factors).

13. Further research directions, if any:

The client exhibiting signs of schizoid personality disorder, who received intervention in this project, exhibits marked deficits in social cognition despite coming from a relatively unremarkable family and social background. When compared to theoretical perspectives on the disorder's etiology, these observations suggest an physical condition associated with the biological features of brain functioning.
