(Un)disclosed. Disease disclosure in people living with rheumatic diseases: An exploratory study.

Objective: Little is known about disease-related disclosure (DD) in patients with rheumatic musculoskeletal diseases (RMDs). We aim to investigate DD behaviors and to explore which socio-demographic, clinical and psychological factors play a role in this self-disclosure process among patients with RMDs.

Methods: A cross-sectional Italian nationwide study captured DD in RMDs in different contexts (workplace, family, friends, partner, social networks).
