Evaluation of the self-reported data to evaluate the trainings
communication behavior
Questionnaires were used before and after the trainings to identify improvements in self-reported perceptions and behaviors. Perceived patient safety, operationalized as triggers for pAEs, communication behavior and self-efficacy to implement good communication was measured. For this purpose, scales with 7 items were used for perceived patient safety (Cronbach’s α = 0.73 at baseline/0.86 post-intervention) and communication behavior (Cronbach’s α = 0.86/0.88). Self-efficacy was measured through general self-efficacy (1 item) and coping with difficult situations (by 4 items; Cronbach’s α = 0.66/0.54). The initial reactions of the participants and their acceptance of the training were captured with a feasibility questionnaire. The questionnaire asked about the healthcare professionals’ experience of the training in terms of the setting (5 items, Cronbach’s α = 0.63), satisfaction with the trainees (2 items, Spearman Rho = 0.63), training content (9 items, Cronbach’s α = 0.89), benefits of the training (8 items, Cronbach’s α = 0.59) and general acceptance (3 items, Cronbach’s α = 0.84). All responses were given on a four-point smiley scale (1 – two negative smileys to 4 – two positive smileys). Additional comments could be added to an open-ended question. Means and standard deviations are reported descriptively.
