Can the biopsychosocial model start in any of the three sectors?

• A. Yes
• B. No
• C. Only in biology
• D. Only in psychology

Answer: (A)

The biopsychosocial model is an integrated framework that includes biological, psychological, and social factors as contributors to health and illness. It does not require starting in one specific domain. You can begin assessment from any sector based on what is most salient or urgent in the patient’s story and presentation.

For example, if someone comes in with acute knee pain and clear tissue involvement, you might initially focus on biological factors like tissue health and biomechanics. But you wouldn’t stop there—psychological aspects (pain beliefs, coping strategies) and social factors (support at home, work demands) should be considered early as they can influence recovery. Conversely, a patient with chronic pain but minimal objective tissue pathology might lead you to foreground psychological factors (fear, catastrophizing, motivation) and social context (workplace stress, access to care) right away. The strength of the model is this ability to address the relevant factors across domains and to see how they interact to shape outcomes.

So, starting point is flexible and guided by the patient’s situation, with ongoing integration across all three sectors to provide comprehensive, person-centered care.
