Abstract

The psychometric properties of measures of self-efficacy for the six themes of Hollandĝ's theory were examined using item response theory. Item and scale quality were compared across levels of the trait continuum; all the scales were highly reliable but differentiated better at some levels of the continuum than others. Applications for adaptive testing methods in educational and career assessment are discussed.
