2. Fig. 1
Relationship between the general factor (overall PCF) and local factors (cognitive deficits, consequences of cognitive deficits, and cognitive capabilities). Note: 1) Bi-factor analysis results show that all items of cognitive deficits and consequences of cognitive deficits have higher loadings (solid lines) on the general factor overall PCF rather than on their own local factors (dashed lines), whereas all cognitive capability items have higher loadings on their local factor (solid lines) than on the general factor (dashed lines). Comparisons of item loadings are shown on Table 3. 2) Model fit: CFI=0.92 and TLI=0.98; RMSEA=0.120.
