“Do You Yourself Have Any Idea What is Going On?”: Invitations for Lay Diagnosis in Dutch Primary Care Physiotherapy.

Lay perspectives are important in the recovery of patients with nonspecific pain as they influence levels of pain and patients’ pain experiences. Although previous interactional research has focused on patients’ unsolicited attempts to share their perspectives, health professions also employ specific techniques to solicit them. Physiotherapists are recommended to assess lay perspectives and include them in treatment. One way to do so is through invitations for lay diagnosis (this paper). However, little is known about how lay perspectives are constructed through these invitations and how physiotherapists follow up on them. In this study, physiotherapy intakes were analyzed using conversation analysis. We found that invitations for lay diagnosis are frequently embedded in previous health care visits or patients’ knowledge gathering activities. Patients often express low epistemic status when they construct their lay perspectives and engage in lay diagnostic activity in response to these invitations. Additionally, physiotherapists’ responses in the third position, such as follow-up questions, may influence the further development of patients’ lay perspectives. These invitations provide patients an opportunity to share their views on their health issues, but also create an interactional challenge due to the reversal of usual epistemic dynamics. The study highlights the complexity of doing lay diagnosis, which can include diagnoses or explanations of varying specificity. The specificity and elaboration of these perspectives are influenced by the physiotherapists’ subsequent responses. We provide recommendations for healthcare professionals to facilitate lay diagnosis, and our findings contribute to the discussion around patient empowerment, shared decision making, and patient centered care.
