a comprehensive model of understanding a person as a single, integrated whole that unites body, mind and behavior. As part of this integration, psychosomatics provides a framework for understanding how untreated psychological stress and emotions translate into palpable physical symptoms, and analyzes the relationship between psychological disorders and organ functions such as the heart, digestive system, and immune system. Psychiatry, in turn, provides specialized knowledge in the diagnosis and treatment of mental illness, mood and personality disorders, focusing on the biological and pharmacological aspects of these disorders, which helps to determine the relationship between psychological and physical symptoms. Clinical psychology contributes to direct therapeutic intervention techniques, including individual, group, and family psychotherapy, coping strategies and behavioral interventions, and accurate psychological and behavioral assessment. By combining these three areas in practice, therapists and physicians can develop multidisciplinary treatment programs that include psychotherapy, behavior modification, pharmacological intervention, and supporting patients in developing coping skills with psychological and physical stress. This integration also allows for the interpretation of medically inexplicable psychosomatic symptoms and the provision of comprehensive care that takes into account the psychological, biological and social aspects of the patient. The practical application of this model contributes to improving the efficiency of diagnosis and treatment, improving mental and physical health, and improving the quality of life of patients by taking into account the mind-body relationship in all aspects of healthcare.
