The Autism Behavior Checklist was completed for 67 autistic and 56 mentally retarded and learning-disabled children (ages 6-15). The checklist was effective in classifying children when using either the full scale or only the more highly weighted items. Results did not support a single unidimensional scale or subdividing the checklist into five…

Utility of the Vineland Adaptive Behavior Scales-Expanded Form to discriminate among areas of adaptive behavior was substantiated by comparing profiles of scores obtained by 113 individuals with mental retardation and either a communication, social behavior, or motor disorder. Results support the use of the Vineland Scales in ecological evaluation…

A classification rule was developed to predict undergraduate students' withdrawal from or completion of fully online general education courses. A multivariate technique, predictive discriminant analysis (PDA), was used. High school grade point average and SAT mathematics score were shown to be related to retention in the online university courses.…

While an adolescent sexual offender's response to treatment is thought to be impacted by both static and dynamic factors, there is no objective method of assessing the likelihood of success or failure in treatment. The assessment of amenability to treatment is generally a subjective process completed by clinicians in the field. Using descriptive…

The purpose of this study was to examine the utility of the Differential Ability Scales (DAS) in distinguishing preschoolers with specific language impairment (SLI) and specific subtypes of language delays. Three hundred forty-eight language-impaired preschoolers' response patterns across DAS General Conceptual Ability (GCA), Ability cluster, and…

As individuals mature, they show increasing responsibility for events in their lives, but with variation in this form of maturation from one individual to another. These individual differences can be observed in doctoral candidates' activities associated with completion of the doctoral dissertation. The purpose of this study was to assess doctoral…

A study examined the differences between 17 children with language disorders and 20 children with normal language development (ages 8-13) in the way they developed shared knowledge with an adult using an interactive communication task. The structure interaction map task involved the child describing a route through a simple schematic map to an…

This study investigated selected attitudinal and demographic factors, involvement, and philanthropic awareness of alumni donors and non-donors from a Research I, public university. A random sample of 500 alumni (250 donors and 250 non-donors) was selected from a population of 37,691, resulting in 371 (74 percent) usable surveys. Discriminant…

Research studies using booklet classification were implemented by the American College Testing Program to investigate the linkage between the National Assessment of Educational Progress (NAEP) Achievement Levels Descriptions and the cutpoints set to represent student performance with respect to the achievement levels. This paper describes the…

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…

This paper identified significant precollege predictors of retention in two freshman classes of a rural college. The subjects of the study were the 1987 and 1988 freshman classes (with 256 and 302 students, respectively) of Chadron State College (Nebraska), a rural college of over 3,000 students. Thirty-three student background variables were…

Specifically designed to avoid methodological problems limiting earlier research, this study attempted to identify specific behavioral differences between elementary school students with either high or low sociometric status. Subjects, who had been selected on the basis of same-sex sociometric status nominations of 144 classmates, were 30 females…

In evaluation research studies, it often occurs that several program participants (experimentals) drop out of the program prior to completion. Since noncompleters generally differ substantially from completers in many respects, a control group which originally was representative of the participant group will most likely not be representative of…

A recategorization system developed by Bannatyne to categorize subtest scatter from the Wechsler Intelligence Scale for Children-Revised (WISC-R) is used as an alternative to isolated analysis of each individual subtest. Reading disabled, learning disabled, and educable mentally handicapped students are categorized according to their performance…

A study was conducted to determine the influence of family background and attitudinal factors on occupational aspirations of Year 9 students in Victoria, Australia. A survey was made of all Victorian Year 9 students and comparisons were made between groups of students who aspired to different occupations. Discriminant function analyses were…
