| The current study is an analysis of the second iteration of an inventory designed to measure Twenty-first Century Skills behaviors and attitudes in college undergraduate students. The initial instrument, a 36-item scale, administered to 594 students, when analyzed for domain consistency using Confirmatory Factor Analysis, failed to meet the criterion for consistent factor loading for the three principal domains it was intended to measure. In accordance with suggestions from the initial measure's results, a second iteration was constructed and administered to 467 students. Using Principal Component Analysis (PCA), the new 95-item self-report survey was analyzed along the three initial major skill dimensions: intrapersonal, interpersonal, and cognitive. The PCA yielded results consistent with the three-dimensional model for which the instrument was constructed. Eight meaningful components were extracted from the Intrapersonal domain, three from the Interpersonal domain, and four from the Cognitive domain. This study offers an analysis of the PCA and internal consistency of the second iteration of the inventory as well as recommendations for further development. |
