Objective To investigate decisional involvement among nurses in general hospitals and analyze its influencing factors, so as to provide reference for improving nurses′ decisional involvement. Methods A total of 2 268 nurses from 4 general hospitals in Hubei province were investigated using the general information questionnaire, the Chinese version of Conditions for Work Effectiveness Questionnaire Ⅱ（CWEQ-Ⅱ-CV） and the Decisional Involvement Scale （DIS）. Results A total of 2 136 valid questionnaires were collected. The total score of DIS was (37.75±11.25) points. Multiple linear regression analysis showed that, formal power, information, resources in structural empowerment and age, level of hospital and monthly income in general information were the predictors of nurses′ decisional involvement (P＜0.05，P＜0.01). Conclusion Nurses′ decisional involvement is in a low level, and it is affected by some factors. Managers should create a working environment that is conducive to nursing professional practice, so as to promote nurses′ decisional involvement level.
