All published empirical studies of the Strong-Campbell Interest Inventory (SCII), 1974 thru 1980, are reviewed. While only a few predictive validity studies have been completed, concurrent and construct validity studies are consistently supportive of the validity of the General Occupational Themes, Basic Interest Scales and Occupational Scales.…

A study was conducted to obtain information about the extent of consumer knowledge of the medical care delivery system and to derive a scale to measure it. A 10-item questionnaire was administered to 4976 persons aged 14-66 in Ohio, Massachusetts, South Carolina, and Washington to measure their consumer sophistication. Some items assessed extent…

The purpose of the study was to assess the reliability and the validity of the Ski Hi Language Development Scale which was designed to determine the receptive and the expressive language levels of hearing impaired children from birth to age 5. The reliability of the instrument was estimated through: (1) internal consistency, (2) inter-rater…

Reading comprehension involves a number of distinctly different intellectual skills that can be assessed if the proper techniques are employed. As part of a reading assessment system, two measures of literal comprehension were developed: the Literal Comprehension Details Test (LCDT) and the Paraphrase Reading Test (PRT). Both the LCDT and the PRT…

Verbal responses to several tests of originality were subjectively rated for originality. The ratings were compared with the statistical frequency of these responses in two samples of test takers, 150 elementary school children and 60 college students. The elementary school children were administered three measures from the Wallach and Kogar test…

The author traces reasons to support his contention that the state of the art in assessing learning disabled students is not good. Among issues examined are the following: use of tests for purposes other than those for which they were intended; technical adequacy of currently used tests (standardization, reliability, validity); the use of deficit…

A high school population (N = 541) was administered the Rotter Locus of Control in April and again the following November. At the second testing the MacDonald-Tseng and Rotter Internal-External Locus of Control Scales were given to examine their concurrent validity. The AIM-ETS Survey and a demographic survey were also administered. Test-retest…

The known interval scale, referred to as the 7.8 scale, has been criticized as an invalid measuring instrument in the form of an attitude scale. It is the purpose of this paper to demonstrate that this scale can produce spuriously inflated correlation coefficients, high reliability, and false significance on statistical tests. The case will be…

Applied Performance Tests (APT) are defined as instruments designed to measure performance in an actual or simulated setting. They require at least a close approximation of the setting (if not the actual setting) to which the performance is expected to be transferred. This paper outlines measurement problems and issues that are unique to APT. It…

The evaluation of a testing program is necessary before or during a sound total project evaluation. Ideally, the testing program study should be concurrent with, and equal in magnitude to, the total project evaluation. Step one in an evaluation is to define the testing program's objectives in operational terms. Step two is a thorough description…

For two tests measuring the same trait, the program, BIV20, equates the scores using the two True score distributions estimated by the univariate method 20 program (see Wingersky, Lees, Lennon, and Lord, 1969) and, with these equated true scores and their distributions, estimates the bivariate distribution scores and the relative efficiency of the…

The item (difficulty and discrimination) and test (reliability and validity) statistics in classical test theory are highly dependent upon the calibration sample of individuals used. The estimates of item and test parameters in classical test theory is valid within a range of interest along the characteristic measured. Generally, this range of…

Section 3 of Phase II of the Pennsylvania Plan is concerned with the adequacy of the educational quality assessment instruments. An overall discussion of reliability--content, criterion related, and construct--is presented. Reliability coefficients for the assessment inventories are provided and empirical studies of validity are described. (PR)

Item options of shortened forms of the Graduate Record Examination Verbal and Quantitative tests were empirically weighted by two variants of a method originally attributed to Guttman. The first method assigned to each option of an item the mean standard score on the remaining items of all subjects choosing that option. The second procedure…
