This study tested the degree to which subscales of the "LASSI for Learning Online" (LLO) (Weinstein & Palmer, 2006), a measure of learning strategies and study skills, predict student success in the form of passing grades, using a combination of large training (N = 4,409) and cross-validation (N = 3,203) samples. Discriminant function analysis…

Starting with the premise that the construct-oriented approach is the only viable approach to personality assessment, this paper considers five propositions. First, a prerequisite to generalizable and valid psychometric measurement of personality rests on the choice of broad-based constructs with systematic univocal definitions. Next, measures…

To identify classroom behaviors that differentiate primary-level students with learning disabilities (LD) from their nondisabled peers, two scales of 83 items each were devised and piloted. Two subscales and 18 individual items were found to discriminate students later classified as LD and those referred but not subsequently classified as LD.…

This study tested the convergent and discriminant validity between two theories of college persistence: the Student Attrition Model and the Student Integration Model. The study examined conceptual similarities for each theory to explain departure decisions and examined how both theoretical frameworks enhanced the understanding of the processes…

The discriminant validity of two subscales of the Reynell Developmental Language Scales (RDLS) was investigated using data from 225 children given the RDLS at age 4 and the Illinois Test of Psycholinguistic Abilities at age 5. Results support the hypothesis; the RDLS scales measure distinct but correlated language abilities. (SLD)

A study used an existing data set to assess the predictive validity of the Armed Services Vocational Aptitude Battery (ASVAB) for civilian occupations. (The ASVAB is a multiple-aptitude test battery used by all military services to determine the qualifications of candidates for enlistment and assign enlistees to military occupations.) The…

The study reported here sought to establish the predictive validity of the Miller Assessment for Preschoolers (MAP), an instrument designed to identify preschool children at risk for school-related problems in the primary years. Children (N=338) in 11 states who were originally tested in 1980 as part of the MAP standardization project were given a…

The validity of teacher locus of control (TLOC) as measured by an instrument adapted for this purpose was studied. The construct refers to the individual's perception that changes in his or her environment result from internal or external factors. An adaptation of a scale developed by R. C. Taylor et al. (1981) was used to measure TLOC. The first…

The Preschool Rating Scale (PRS) consists of twenty Guttman scaled items which assess a preschool child's personal-social development. Experience gained over the past two years indicate that it can be used: (1) for screening; (2) for program evaluation; (3) as a guide to the teachers in identifying specific areas of development which may need…
