The Vanderbilt Negative Indicators Scale (VNIS), an instrument designed to quantify characteristics of the patient, the therapist, and their interactions, was developed as part of an investigation of negative effects in psychotherapy by the Vanderbilt Psychotherapy Research Team. Revision of the original 25-item scale has proceeded in two major…

The attitude of students toward taking achievement tests, as well as the relationship between this attitude and student performance on achievement tests, was studied in three southern Illinois schools. Students in grades six through nine were administered the 1973 Stanford Achievement Tests, followed by an attitudinal test developed for the study…

A NEED FOR AN ADEQUATELY DEVELOPED AND STANDARDIZED INTELLIGENCE SCALE IN THE WHOLE OF LATIN AMERICA RESULTED IN THE WAIS PROJECT WHOSE AIM WAS TO TRANSLATE INTO SPANISH, ADAPT TO SPANISH CULTURE, AND STANDARDIZE THE WECHSLER ADULT INTELLIGENCE SCALE IN PUERTO RICO. FOLLOWING A DISCUSSION OF THE FOUR GENERAL GOALS, THE PROJECT REPORT OUTLINES THE…

To contribute to a more differentiated description of the cognitive status of young disadvantaged children, a comparative study was made of achievement test performance of disadvantaged and middle class groups of children. On the basis of published reading test scores, test data were gathered from nine public schools, four of which were selected…

This study used a series of simulations to answer questions about the efficacy of adaptive testing raised by empirical studies. The first study showed that for reasonable high entry points, parameters estimated from paper-and-pencil test protocols cross-validated remarkably well to groups actually tested at a computer terminal. This suggested that…

Measures of consistency and completeness of order relations derived from test-type data are proposed. The measures are generalized to apply to incomplete data such as tailored testing. The measures are based on consideration of the items-plus-persons by items-plus-persons matrix as an adjacency matrix in which a 1 means that the row element…

When classes are the units of analyses, estimates of the reliability of class means are needed. Using classical test theory it is difficult to treat this problem adequately. Generalizability theory, however, provides a natural framework for dealing with the problem. Each of four possible formulas for the generalizability of class means is derived…

A method for developing statistically parallel tests based on the analysis of unique item variance was developed. A test population of 907 basic airmen trainees were required to estimate the angle at which an object in a photograph was viewed, selecting from eight possibilities. A FORTRAN program known as VARSEL was used to rank all the test items…

Several tenets of mastery learning were examined in this study in the context of college level instruction. When students learn for mastery: (1) retention test scores should exhibit small variability and should be unrelated to aptitude; (2) test items which are classified into high and low cognitive behavior subscales should be unrelated to…

The Language Analysis Package (LAP) was developed by the Southwest Regional Laboratory (SWRL) to assist researchers in the analysis of language usage. The function of the KWIC (Keyword-in Context or Concordance) Module of the LAP is to produce keyword listings from the input text being analyzed. Such listings will contain location information…

A class of first graders and a class of second graders in four Salt Lake City schools comprised the experimental sample in a study whose objectives were (1) to develop a test for assessing learning with "Our Working World" materials, published by Science Research Associate (SRA), and (2) to determine if students using the materials made…

Research objectives were: (1) to establish norm data from a battery of creativity tests, (2) to obtain frequency of response scores for the originality sub-test (Guilford) to compare with scorer judgment type "remote" scores, (3) to perform an item analysis, (4) to analyze and report on the relationship of creativity, socio-economic status, I.Q.,…

This report deals with the further validation of the Environmental Deprivation Scale (EDS) as a predictor of criminal behavior and recidivism. The EDS measures the degree of supportive environmental input through 16 items assessing occupation, organizational activities, and interpersonal relationships. The data were obtained in behavioral…

The problems stated at the outset were: to discover whether information provided by confidence testing would result in a more accurate assessment of student knowledge so more personal individualized instruction could be presented, and whether sufficient precise data could be attained to be of significant aid in curriculum planning. Analysis has…

An attempt is made to indicate why the concept of "true score" naturally leads to the belief that test validity must increase with an increase in test and/or average item reliability, and why this is correct for the classical single-factor model first introduced by Spearman. The statistical model used by Loevinger is introduced to…
