OBJECTIVE: To conduct a conceptual analysis of patient self-disclosure in the nursing literature to identify attributes, antecedent requirements, consequences, and definitions of self-disclosure. METHODS: Databases such as Ichushi web were searched using "self-disclosure," "patient," and "nursing" as keywords. Finally, references were extracted and analyzed by Rodgers' method. Results: Four attributes were extracted, including "thoughts about illness" and "thoughts about living with illness," five antecedents, including "having support for disclosure" and "having motivation to disclose," and five consequences, including "obtaining support" and "leading to self understanding and behavior change. Discussion:One of the most important findings of this study is that self-disclosure results in gaining support from those around them. Research on self disclosure in psychology has revealed only the effects on the discloser him⁄herself. However, the fact that the present study revealed the relationship with the people around the patient as a result of self-disclosure is a characteristic of nursing that differs from that of psychology. In the nursing literature, patient self-disclosure is defined as " a person with an illness has his or her own factors such as motivation and skills to self-disclose, as well as support from others, to be able to convey the thoughts of living with illness and to request support from those around them, which lead to personal factors such as self-understanding and behavior change, as well as support and improvement of the quality of nursing."
