Objective To establish norms for the Caring Behaviors Inventory in grade Ⅲ tertiary general hospitals in China, and to provide reference for evaluating nurses′ caring behavior. Methods A total of 3,807 clinical nurses were selected from six grade Ⅲ tertiary general hospitals in North, Northeast, East, Central South, Southwest and Northwest China by stratified cluster sampling method and completed the Chinese version of Caring Behaviors Inventory. The normed scores were identified by using means, percentiles, grades and groups. Results Sample mean score was 77.01 (standard deviation=17.36), and the lower quartile, median and upper quartile were 60.00, 80.00 and 92.50 respectively. Five grades were determined: very low,low, medium, relatively high and high. Distinct norms for gender, age, marital status, education level, professional title, professional post and length of work were also identified. Conclusion These norms can be used for measuring caring behavior of clinical nurses in grade Ⅲ tertiary general hospitals in China.
