The research reported in this article addresses the fundamental issue of measurement of the construct worldview. Specifically the issue of how to measure a person's worldview as related to the creation/evolution controversy is considered. Data were collected via a LIKERT-scale instrument constructed for the specific purpose of measuring a "Young Earth Christian Creationist Worldview." The analysis of data revealed some weaknesses in the design and individual questions. Reliability and validity of the instrument was explored. The preliminary investigation reveals that the construct under consideration most likely can be measured successfully.
