Model fit indices based on confirmatory factor analyses of one-, CU-, and three-factor models along with tests of the three-factor model among boys and girls and in the three age groups
| N | RMSEA | CFI | TLI | |
|---|---|---|---|---|
| One-factor model | 1742 | .12 | .91 | .90 |
| CU-factor model | 1742 | .12 | .99 | .98 |
| Three-factor model | 1742 | .07 | .96 | .96 |
| Boys | 903 | .07 | .97 | .97 |
| Girls | 839 | .07 | .96 | .96 |
| 3-year-olds | 591 | .07 | .98 | .97 |
| 4-year-olds | 574 | .07 | .97 | .96 |
| 5-year-olds | 577 | .07 | .97 | .97 |
The N’s are lower than 2,056 (the total sample) because of individual missing items. Estimation method is robust WLS. RMSEA root mean square error of approximation; CFI comparative fit index; TLI tucker-lewis index
