Final answer:
The problem with Dr. Stephen’s categorical approach in diagnosing psychological disorders using the DSM is that it lacks precision and subtlety. A categorical approach may overlook important variations and nuances in a patient's condition, leading to misdiagnosis or ineffective treatment.
Step-by-step explanation:
The problem with Dr. Stephen’s categorical approach in diagnosing psychological disorders using the DSM is that it lacks precision and subtlety. Categorical models, such as the DSM, divide disorders into distinct categories with clear boundaries. However, mental disorders often present with a range of symptoms and can vary in severity, making it difficult to fit every patient into a single category.
For example, depression can manifest differently in different individuals. Some may experience severe symptoms, while others may have less severe symptoms. Some may exhibit classic signs of depression, while others may have atypical symptoms. By relying solely on a categorical approach, Dr. Stephens may overlook important nuances and variations in his patient's condition, leading to misdiagnosis or ineffective treatment.
Instead, a dimensional approach, which allows for a more nuanced understanding of disorders and their severity, may provide a more accurate and comprehensive diagnosis. This approach considers various dimensions of mental health, such as symptom severity, duration, and functional impairment, allowing for a more personalized and tailored treatment approach.
