Table 2. Principal Components Analysis Validating Composites.
The following pattern matrix was derived from the principal components analysis, which yielded four independent components (eigenvalues ≥ 1.0) validating our four sub-composites: (1) Cognitive Efficiency, (2) Memory, (3) Gross Motor, (4) Fine Motor. Loadings ≥ .40 are shown.
