Background Well analyzed generally accepted concepts can help the nurse identify and solve complex care situations and thus more easily communicate with patients and ascertain their needs, develop nursing diagnoses and choose the appropriate nursing interventions.AimThe aim of this study was to unveil the concept of dialogue and elucidate its meaning. Method The concept analysis method developed by Koort was used. Results The analysis revealed that the word dialogue was first mentioned in the early 1200s and is derived from the old French word "dialoge". The concept of dialogue is described as a conversation between two people. When dictionaries and encyclopedias were reviewed we found twenty eight synonyms for the concept of dialogue, on further examination it emerged that many of the words were not relevant to nursing science. Conclusion Dialogue is an attitude characterized by proximity, a mutual exchange takes place between two or more people. The relationship between a health professional and a patient should be characterized by both seeing themselves as free and by recognizing that both of them have the knowledge needed for the patient to regain health. Both parts have obligations, rights and responsibilities towards each other.
