Background & Aim: Although caring is a complex concept with various definitions, there are no agreement on the exact meaning among researchers. The aim of this study was to compare caring behaviors of nurses from patients&apos and nurses&apos perspectives.

Methods & Materials: The study was conducted among 150 patients hospitalized in Boushehr hospitals and 50 nurses caring for them. Data were collected using quota sampling method via Caring Behaviors Inventory (CBI).

Results: Findings showed that there were significant differences between patients&apos and nurses&apos perspectives on the subscales of the instrument including assurance of human presence and attentiveness to others&apos experiences. Moreover, there was significant difference in total scale of caring behaviors of nurses between patients and nurses (t=2.559, P=0.011).

Conclusion: Nurses believed that they provide care for patients without making estimations of their expectations. It seems that nurses should attend to standard care to fill the gap
