An Empirical Test of Roskam's Conjecture about the Interpretation of an ICC Parameter in Personality Inventories.
Zumbo, Bruno D.; Pope, Gregory A.; Watson, Jackie E.; Hubley, Anita M.
Educational and Psychological Measurement, v57 n6 p963-69 Dec 1997
E. Roskam's (1985) conjecture that steeper item characteristic curve (ICC) "a" parameters (slopes) (and higher item total correlations in classical test theory) would be found with more concretely worded test items was tested with results from 925 young adults on the Eysenck Personality Questionnaire (H. Eysenck and S. Eysenck, 1975). Results did not support Roskam's proposed interpretation. (SLD)
