RESUMEN
BACKGROUND: Effective communication is essential for nursing students to provide safe patient care. Many communication consensuses focus on physician-associated communication rather than nurses' interpersonal communication. However, studies on developing a systematic and comprehensive communication knowledge system for nursing students are scarce. OBJECTIVES: To explore the teaching content and teaching framework of nurses' interpersonal communication, construct a systematic and scientific knowledge system for interpersonal communication among nursing students and provide a theoretical basis for the training of nurses on interpersonal communication. METHODS: Based on the literature review and comparative research, this study explored the theoretical basis and basic principles of constructing an interpersonal communication knowledge system for nurses. Moreover, a correspondence questionnaire on nurses' interpersonal communication knowledge systems was initially constructed to clarify the related teaching content and structure. Finally, the Delphi method was used to establish the index of the nurses' interpersonal communication knowledge system according to the principle of expert selection and inclusion criteria. RESULTS: The Delphi method included 26 experts from nursing education, clinical nursing, nursing management and other fields for consultation. The effective response rate of the letter inquiry was 96.3 % in the first round and 100 % in the second round. The judgment basis, familiarity and authority coefficient of expert consultation were 0.907, 0.862 and 0.884, respectively. In the two rounds of inquiry, the coordination coefficients of the total questionnaire were 0.228 and 0.302, which was statistically significant (P < 0.001). Thereafter, a wheeled model of nurses' interpersonal communication knowledge system with 3 primary indicators, 13 secondary indicators and 58 tertiary indicators was constructed, which included professional ethics and attitude, communication knowledge and communication skills. CONCLUSION: Literature and comparative research methods along with Delphi expert consultation were used to construct a scientific and systematic knowledge system of nurses' interpersonal communication. The research methods were feasible, and the results were scientific and reliable, thereby providing a basis for the education of nurses' interpersonal communication among nurses and the compilation of related teaching materials in China and globally. Furthermore, special attention should be paid to the comprehensive cultivation of nursing students' professional ethics and attitude, communication knowledge and communication skills.
