The second purpose is to provide details on the procedures used to assess the underlying factor structure of the complete questionnaire. Factor analysis procedures (specifically, a principal factors approach with both varimax orthogonal and promax oblique rotations) were used for both purposes. Eleven items, which loaded heavily on the first factor of a two-factor common factor solution with promax oblique rotation, were selected to create a computer familiarity score. This score was then used to classify TOEFL examinees into one of three familiarity groups: low, moderate, and high. A four-factor common factor solution with promax oblique rotation was seen as providing the best accounting of the underlying factor structure of the complete questionnaire.
