Fig. 3: Bar graph of factor loadings of the questions in the PNA and IDK confirmatory factor analyses.

For each item in the analysis: a, The fitted loadings of PNA responses on each latent factor in the CFA with the selected bifactor model for PNA. b, The fitted loadings in CFA of the bifactor model for IDK. Error bars indicate ±1 s.e. Loadings without bars were constrained to 0 in the corresponding CFA.
