INFORMATION ABOUT THE MASTER'S PROJECT

1. Student's full name: Le Manh Thuong 2. Gender: Male

3. Date of birth: January 14, 1986

4. Place of birth: Nam Dan, Nghe An

5. Decision No. 4058 dated December 28, 2022, of the Rector of the University of Social Sciences and Humanities, Vietnam National University, Hanoi, recognizing the student.

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

7. Project Title: Psychological Therapy for a Case Showing Manifestations of Schizoid Personality Disorder.

8. Major: Clinical Psychology; Code: 8310402

9. Scientific supervisor:

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

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

10. Summary of project results:

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

The client received cognitive-behavioral therapy (CBT). Intervention results showed some improvement in life functions, a reduction in maladaptive behaviors, and increased ability to recognize negative emotions. However, maladaptive thoughts generally changed little, and manifestations of detachment/schizophrenia remained prominent.

11. Practical applications:

Based on theoretical issues and results obtained in clinical intervention practice, this project provides further evidence on the effectiveness and limitations of cognitive-behavioral psychotherapy for schizoid personality disorder (without excluding factors related to therapist competence).

12. Future research directions: Clients exhibiting symptoms of schizoid personality disorder who underwent intervention in this project revealed significant deficits in social and cognitive functions within a not-too-unusual family and social context. This, when compared with theoretical perspectives on the causes of the disorder, suggests a physical condition related to the 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.
