To assess the validity and reliability of the SBI in medical surgical specialists working in fourteen health care facilities in Antioquia (Colombia) in 2018. Methods. The study was conducted in 14 healthcare institutions among 8 surgical specialties. The tool consists of 20 items collected by means of face-to-face interviews under the supervision of a psychologist, and maintaining confidentiality. The psychometric assessment included content validity (CV), construct validity using confirmatory factor analysis (CFA) and reliability using Cronbach’s Alpha. Results. The study sample consisted of 234 participants. CV of the tool was 0.82. The CFA showed acceptable model fit, with the results of goodness-of-fit being χ2=384.578 (p
