Improving Selection for Surgical Training: Using Virtual Reality and Gamification for Assessment of Technical Skills, Cognitive Abilities, and Personality Characteristics
Dr. Noa Gazit-Dadush - Hebrew University of Jerusalem
The selection of candidates for surgical training is a crucial step in identifying the most suitable candidates for a surgical career. However, in most surgical programs worldwide the selection process is based on ineffective methods such as CVs, academic achievement, letters of recommendation, and unstructured interviews, which show zero to low correlation with later performance during residency. Traditional personnel-selection tools (e.g., dexterity tests, visuospatial ability tests, and personality questionnaires) have also been examined but have not been found suitable for selecting candidates for surgical training. Therefore, the aim of this research was to develop improved selection tools and to validate their use in the selection of candidates for surgical training.
The research included three phases. In Phase 1, a job analysis was conducted to identify the competencies required of surgeons in the 21st century. Based on interviews with expert surgeons (N = 104), 24 competencies were identified: five technical skills, six cognitive abilities, and 13 personality characteristics. This list was later validated using a questionnaire completed by a large sample of surgeons and residents (N = 1,102). In Phase 2, two virtual reality (VR) game-based assessment tests were developed: a technical aptitude test using a VR laparoscopic simulator and a computer game-based assessment of cognitive abilities and personality characteristics. Finally, in Phase 3, validity evidence for the tests was examined using data collected from interns, residents, and expert surgeons. The findings provided significant evidence for the validity, fairness, and feasibility of the tests and support their use in the selection of candidates for surgical training.
In summary, the dissertation presents the systematic development and evaluation of two VR game-based assessments with the potential to improve the selection process for surgical training. Improving the selection process may contribute to improving the quality of the surgical workforce and patient care.
