Aim: To evaluate the transition of behavioural changes of participants before and after the training using a scale that can objectively evaluate coaching training for nurses.
Design: After a cross-sectional study, a quasi-experimental study was conducted.
Methods: We examined the reliability and validity of the Coaching Skill Assessment plus (CSAplus), which was developed to measure the effectiveness of coaching training for corporate leaders. Next, a repeated measures analysis of variance was conducted on two types of coaching training for nurses conducted at a university hospital, with the CSAplus scores of participants before, 1 month and 6 months after the training as the dependent variable.
Results: The CSAplus is a three-factor instrument with good reliability and validity. Participants' CSAplus scores improved after training, but there were differences in the magnitude and persistence of the training effects.
Public contribution: Hospital staff, professional coaches and their clients were involved in data collection.
