Proposes a factorial procedure for investigating differential distractor functioning in multiple choice items that models each distractor with a distinct distractibility parameter. Results of a simulation study show that the parameters of the proposed modeling were recovered very well. Analysis of 10 4-choice items from a college entrance…

Examination of a test's internal structure can be used to identify what domains or dimensions are being measured, identify relationships between the dimensions, provide evidence for hypothesized multidimensionality and test score interpretations, and identify construct-irrelevant variance. The purpose of this research is to provide a…

The construct validity of biographical items in the Individual Achievement Record (IAR) was assessed in an attempt to develop a confirmatory factor model. This first phase of a two-phase study focused on the IAR's use as a predictor of job performance. The IAR is an empirically keyed biodata inventory containing 112 multiple-choice items. Item…

This study examined the relationship of multiple-choice and free-response items contained on the College Board's Advanced Placement Computer Science (APCS) examination. Subjects were two samples of 1,000 randomly drawn from the population of 7,372 high school students taking the 1988 examination of the APCS "AB" form. Most were high…
