Abstract
This dissertation examines the extent to which personality items that were
developed to describe personality in general are adequate descriptors of personality
within a specific context. This research provides for a deeper understanding of
contextualized personality assessment by examining the effects of item context
specificity and perceived context relevance on the measurement properties of Big Five
Conscientiousness facets within the contexts of work and school. Results indicate that an
item’s discrimination is related to its perceived context relevance and its level of context
specificity. Implications for the improved measurement of personality are discussed.
