The biopsychosocial model was initially proposed to overcome the normative assumption that human diseases are exclusively due to disordered biochemical and/or neurophysiological processes. The model attempts to explain how expectations, thoughts and feelings modify the patient’s motivations to deal with illness and recovery. By considering the physical health in this perspective, healthcare professionals may test the importance of socially and culturally shared principles in alleviating illness experience. The entire biopsychosocial hierarchy may thus appear as a complex network of relationships between (...) the strict logic of scientific explanations and the emotional sustainability with which beliefs may either be defended, changed or even refused. In this paper, we aim at reviewing some of the evidence-based biomedical and psychological findings that provide a unified framework for the biopsychosocial model as a multilevel integrative process. To tackle this objective, we propose to approach the model in biosemiotic terms. It is our contention that the entire biopsychosocial hierarchy could be better understood if approached biosemiotically and the multilevel interconnection of this hierarchy re-examined in the light of a collaborative meaning-making process.
