The present study investigated the differential predictive validity of the Initial Skills Analysis. In the fall, these reading screening tests were administered to students in Grades K to 3. In the spring, a series of reading outcomes tests were administered to these same students, and teachers provided judgments of the students' reading skills.…

This article presents results from two interrelated studies. The first study conducted a meta-analysis of the published literature since 1990 to determine the magnitude of achievement problems associated with attention-deficit/hyperactivity disorder (ADHD). Effect sizes were significantly different between participants with and without ADHD…

Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…

A longitudinal study determined if children's invented spelling served as a viable predictor of reading achievement and compared the predictive value of assessing children's invented spelling relative to other notable predictors, such as letter names, letter sounds, a concept of a word, and phonemic awareness. Subjects, 52 kindergarten children…

The Drug Abuse Reporting Program (DARP) was initiated in 1969 as a federally supported client reporting system for community-based drug abuse treatment programs. Posttreatment follow-up interviews were conducted with over 4,000 persons from 34 treatment agencies to describe major findings from the drug abuse treatment research of the DARP relating…

One purpose of this study was to compare the incremental effectiveness over high school grade point average (GPA) alone of the American College Testing Program (ACT) assessment, the Scholastic Aptitude Test (SAT), and the California Achievement Tests (CAT) in predicting college freshman GPA. A second purpose was to look at the relative…

The use of two-stage least squares (2SLS) for the estimation of feedback linkages is inappropriate for nonorthogonal data sets because 2SLS is extremely sensitive to multicollinearity. It is argued that what is needed is use of a different estimating criterion than the least squares criterion. Theoretically the variance normalization criterion has…

THE HABILITATION OF EDUCABLE MENTALLY RETARDED YOUTH WAS STUDIED TO DETERMINE THE EFFECTIVENESS OF PREDICTOR VARIABLES. TESTS AND INTERVIEWS BY QUESTIONNAIRES WERE MADE ON 5 GROUPS OF YOUTHS WITH 25 IN EACH GROUP. DATA WERE ANALYZED TO DETERMINE THE RELATIVE WEIGHTS OF EACH VARIABLE AND MEASURE. DIFFERENCES AMONG THE EXPERIMENTAL GROUPS WERE…

This study is phase one of a 4-year project. It was aimed at examining the predictive validity of six preschool screening instruments on later academic achievement. The six instruments were (1) the Stanford-Binet Intelligence Test, (2) the Sprigle School Readiness Screening Test, (3) the Anton Brenner Developmental Gestalt Test of School…

The relationships between grades of Hofstra students at the end of the freshman year and such predictor variables as high school standing and scores on the SAT are considered. Data are also presented on the overall performance of the class and on the relationship between performance of students who stayed at Hofstra and those who dropped out.…

Compared three methods of rating thoughts: self-rating by subjects, rating by experts with thoughts presented randomly, and rating by experts with thoughts presented in context among 107 students who listed their thoughts prior to giving a speech. Results indicated all three methods were equal in predictions of speech anxiety and performance.…

Insufficient predictive validity on academic variables of the Structure-of-Intellect Learning Abilities Test Gifted Screening Form (SOI-LA-GSF) was found with 172 gifted grade four and 109 gifted grade seven students. The predictive validity of other measures was examined with 107 grade 10 students. (MC)

Using the Watson-Barker Listening Test Form A and Form B as pretest and posttest at the freshman level, this research attempted to determine whether the two forms of the test and the differences between pretest and posttest would be significant predictors of students' final grade point average (GPA). Each form of the test was taken by 190 students…

Examined the scale characteristics of two measures of organizational commitment. Using data from l,l05 accountants, findings indicated that while both instruments exhibited a high degree of internal reliability, the Porter et al. (1947) instrument exhibited significantly greater predictive validity with respect to intended turnover than the…

Tested models of interests by examining the significance of disconfirmed ordinal predictions. Examined data regarding Holland's hexagonal model and Roe's circular ordering. Tested adequacy of the hierarchical model and compared significance of the disconfirmed predictions of the hierachical model to that of the hexagonal-circular model. (Author)
