Abstract

The aim of this study was to translate, culturally adapt and validate the TRUST questionnaire in a Greek perioperative setting. The TRUST questionnaire assesses the relationship between trust and performance. A bilingual translation and pre-test process was followed. Internal consistency, reproducibility (test-retest) and criterion validity were calculated (Cronbach's alpha, kappa correlation coefficient, bivariate analysis). Overall internal consistency presented very high alpha values for individual comparison (Cronbach's =0.97, 95% CI=0.95–0.99, P value<0.001). The reproducibility and construct validity (Pearson r=0.86, P value<0.001) were retained at very good levels. According to factor analysis, two factors were extracted with eigenvalues>1 (KMO=0.83, Barlett's test of sphericity P value<0.001). The study assessed the levels of trust and performance in the surgery and anaesthesiology department during a very stressful period for Greece (economic crisis) and offered a user friendly and robust assessment tool. The study concludes that the Greek version of the TRUST questionnaire is a reliable and valid instrument for measuring team performance among Greek perioperative teams.
