Study procedure
RECRUITMENT
The study was held in Clalit Health Services outpatient clinics. At the beginning of the training, the first author (HA) visited each clinic. He gave the CE and the students an explanation of the study’s goals and methods. Participants’ characteristics and written consent were obtained from all the CE and students. The CE received a research envelope that included the APP forms and a randomization sealed envelope.During week four of the training, the CE conducts a mid-term assessment meeting. The CE was asked first to evaluate all students using the APP and only then to proceed with randomization. The CE let each student choose one of the sealed envelopes. Only one student received an envelope with an intervention sign. This student performed a self-assessment using the APP form before the mid-term assessment meeting. During the meeting, students receive feedback and assessment regarding their performance based on CE evaluation using the APP form. Students in the IG received mid-term assessments taking into consideration the assessment form filled out by the CE and the self-assessment form filled out by the student himself. Students in the CG received mid-term assessments based on the APP form filled out by the CE. These APP files were placed in an envelope and sent to the first author.At the end of the clinical training, during week 8, CE asked to evaluate all students. In addition, all the students in IG and CG were asked to perform self-assessments using the APP form. These assessment forms were not included in the final assessment meeting as they were explicitly done for the study and not for the official assessment that was sent to the educational institution. These APP files were again placed into an envelope and sent to the first author.The CE and the students were asked not to calculate the total score of the APP.Flowchart
