***p 0.001; **p 0.01; *p 0.05 (one-tailed test based on 5000 bootstrap replications). Coefficients in the diagonal are the squared root of AVE. Coefficients below the diagonal are correlations among the latent variables in the model. Because gender, age, and endoscopy experience are observed variables, their CR and AVE are by definition equal to 1.00. .AVE, Average Variance Extracted; CR, Composite Reliability.
