Beyond initial disclosure: the role of prognosis and symptom uncertainty in patterns of disclosure in relationships.

This study is framed in Greene's (2009) health disclosure decision-making model (DD-MM) and explores the role of prognosis and symptom uncertainty in patterns of disclosure in a close relationship. Toward this end, an uncertainty and disclosure model is hypothesized in which prognosis and symptom uncertainty and relational quality are expected to predict perceived partner support, communication efficacy, and the depth, breadth, and frequency of disclosure to a partner about a chronic health condition. Patients with diagnosed heart-related conditions visiting a private medical office were recruited to complete anonymous surveys. Results indicated that (1) the key mechanisms identified in the DD-MM are associated with the depth, breadth, and frequency of disclosure to a partner about a health condition, and (2) uncertainty plays a prominent role in people's communication with their partner about the heart-related condition. The findings and implications of the study are discussed.
