  1. Values between parentheses are standard deviations. Values among brackets show confidence intervals. Latent scores are weighted scores by factor loadings and thresholds parameters estimated using the “Residuals”, and summative scores add up equally weighted items.
  2. For the latent scores, minimum value is −2.24 and maximum is 5.47; and for the summative score minimum value is 19 and maximum is 76.
