Note. α = estimated slope parameters; β1, β2, and β3 = estimated category threshold parameters. Standard errors of the estimated parameters are presented in parentheses. Results for the egocentricity subscale is not available as the subscale did not meet the unidimensional assumption for IRT analyses.
