Objective To explore the latent profile characteristics of self-disclosure in patients with heart failure, and to analyze its relationships with self-management behaviors, so as to provide a reference for taking targeted interventions to improve patients′ self-management levels.Methods A convenience sampling was used to select 350 inpatients with heart failure, then they were investigated by using a general information questionnaire, the Distress Disclosure Index Scale,and the Self-Management Scale of Heart Fai-lure Patients.Results The self-disclosure score of the participants was （33.87±8.36） points, which was classified into three latent profiles:low disclosure-silent type （40.6%）, moderate disclosure-chatting for diversion type（36.6%）, and high disclosure-confi-ding to relieve sorrow type （22.8%）.There were statistically significant differences in self-management scores among patients in different self-disclosure profiles （P＜0.05）.Conclusion The self-disclosure in patients with heart failure exhibits a moderate level with significant heterogeneity, and the self-management behaviors vary among patients in different self-disclosure profile categories.Medical staff should develop targeted intervention strategies based on the characteristics of different profiles of self-disclosure, so as to enhance patients′ self-disclosure willingness, and promote their self-management level.
