More details about my question are my topic is how senior nurses' perception of transformational leadership influences their practices, job satisfaction, management skills, and organizational commitment.
I can introduce some articles in this field. There are also governorship questionnaires about each of these things you mentioned, including leadership styles and job satisfaction.
I've found the MLQ-Short to be a good tool to help determine transformational leadership. Here is a link to a resource you can use to access it. Multifactor Leadership Questionnaire (MLQ) - Tests, Training - MindGarden.com. The reliability and validity of are really good and there is an ease of use with the tool.
