The release of the newest Sixteen Personality Factor Questionnaire (16PF), Fifth Edition, is the evolution of Raymond Cattell's conceptualization of the primary components of personality by analyzing adjectives describing human behavior. This updated version continues to measure the same 16 primary personality factors with improved reliability and…

Three methods for the estimation of the reliability of single dichotomous items are discussed. All methods are based on the assumptions of nondecreasing and nonintersecting item response functions and the Mokken model of double monotonicity. Based on analytical and Monte Carlo studies, it is concluded that one method is superior to the other two…

This collection contains four papers that were presented as part of a short course delivered at the 1991 annual meeting of the Speech Communication Association. The papers discuss various aspects of the development and use of "The Competent Speaker," a public speaking assessment instrument designed for the college sophomore level. The papers and…

This paper discusses research conducted in the spring of 1991 that measured the relationship of reading subtest scores to teacher ratings of students' reading abilities. Sixty-eight advanced-level students in an intensive English program took an institutional version of the Test of English as a Foreign Language (TOEFL) and a specimen reading…
