Most patients trust their physicians uniformly across several situations, which challenges prevailing perspectives on interpersonal trust that view it as situated (placed upon a specific person for a specific task within a situation). We suggest this finding is an artifact of undertheorizing about how situations shape patients’ trust. We develop claims explaining how patients’ devalued health characteristics raise situation-specific concerns. We find that the severity and chronic severity of body weight and depressive symptoms are associated with lower trust in physician confidentiality-–-the expectation that a physician uses personal health information appropriately-–but not trust for other tasks.
