In DSM-IV, Axis 3 includes which type of information?

• A. Psychological factors
• B. Medical/Physical conditions
• C. Environmental stressors
• D. Global assessment

Answer: (B)

Think of DSM-IV’s five-axis structure as a way to capture different aspects that matter for understanding and treating a person. Axis III is specifically about general medical or physical conditions that may affect the mental disorder’s presentation, course, or response to treatment. Examples include endocrine disorders like thyroid problems, metabolic issues like diabetes, neurological conditions or head injuries, chronic illnesses, and other physical illnesses. These medical factors can influence symptoms, prognosis, or how you plan care, so they’re noted here.

Other aspects fit on different axes: environmental stressors and psychosocial problems are on Axis IV, and the Global Assessment of Functioning score goes on Axis V. Psychological factors themselves aren’t listed on Axis III, since they’re categorized under the clinical diagnoses on Axis I or personality issues on Axis II.
