An Instrument Validation for a Three-Dimensional Worldview Survey among Undergraduate Christian University Students Using Principal Components Analysis

Abstract

This quantitative study examined the structure, validity, and reliability of the Three-Dimensional Worldview Survey-Form C (3DWS-Form C) for potential use in postsecondary Christian institutions. This instrument delineates from other worldview instruments in that it purports to measure three components of a person's worldview: propositions, behaviors, and heart-orientation. Principal components analysis (PCA) was used to examine the underlying component structure and construct validity of the instrument. Cronbach's alpha and the Spearman-Brown prophecy formula were used to assess the internal consistency and reliability of the instrument. Participants were first-year university students attending a large Christian university in Virginia. Results of the study indicated the presence of a three-component structure, although item loadings were not consistent with previous research.
