| Standard deviation | 9.2649 | 3.4241 |
| Proportion of variance | 0.7505 | 0.1023 |
| Cumulative proportion | 0.7505 | 0.8530 |
Heavy loadings of each component are shown in bold. The proportion of variance indicates the percentage of variation in the observed behavioral variables explained by each principal component (PC). Cumulative proportion indicates the sum total percentage of variation in the observed behavioral variables explained by a given PC and its preceding PCs.
