Table 4.
Fit indices for the Full Model and nested Executive Function Only and Verbal Memory Only models (N = 336).
Model | χ2 | df | p | Comparative Fit Index (CFI) | Root-Mean-Square Error of Approximation (RMSEA) | Standardized Root-Mean Square Residual (SRMR) | Akaike Information Criterion (AIC) |
---|---|---|---|---|---|---|---|
Full Model | 65.50 | 43 | .02 | .98 | .04, 90% CI [.02, .06], pclose = .81 | .03 | 9210.91 |
Executive Function Only | 70.20 | 46 | .01 | .98 | .04, 90% CI [02, .06], pclose = .82 | .04 | 9209.61 |
Verbal Memory Only | 89.36 | 46 | < .001 | .96 | .05, 90% CI [.04, .07], pclose = .36 | .05 | 9228.77 |
Note. In the Executive Function Only model, all indirect paths to Achievement Change through Verbal Memory were constrained to zero. In the Verbal Memory Only model, all indirect paths to Achievement Change through executive function were constrained to zero.
