Two new reliability coefficients have been derived for situations in which a test must be divided into parts of unequal length. This report summarizes a study of the statistical bias and the standard errors of these coefficients and compares them to Guttman's lambda coefficients and Cronbach's alpha coefficient. (Author/JKS)

Reports the test-retest reliabilities for the Schedule of Recent Experiences (item counts) and the Recent Life Changes Questionnaire and compares the two scales. Subjects (N=109) were men and women enlisted in the US military reserves. Results indicated the two questionnaires demonstrate acceptable test-retest reliability. (BH)

The Autism Reinforcer Checklist was found to have adequate reliability when used with 29 autistic children (preschool-early adolescence). Results indicated highest and lowest ranked reinforcers of the edible, material, social, and activity type. (CL)

Several algorithms for computing the greatest lower bound to reliability or the constrained minimum-trace communality solution in factor analysis have been developed. The convergence properties of these methods are examined. A uniqueness proof for the desired solution is offered. (Author/JKS)

One argument against the G index is that, unlike phi, it is not a correlation coefficient; yet, G conforms to the Kendall and E-coefficient definitions. The G index is also equal to the Pearson product moment correlation coefficient obtained from double scoring. (Author/CP)

Examines psychometric reliability of Drug Use Screening Inventory (DUSI) utilizing adolescents with DSM-III-R diagnosis of Psychoactive Substance Use Disorder. Concludes that split-half, internal, and test-retest reliability is superior. Suggests that DUSI may be useful for identifying and quantifying substance use and related problems. Includes…

This research study is the report of an experiment conducted to find out the effects of web based inquiry science environment on cognitive outcomes in Biological science in correlation to Emotional intelligence. Web based inquiry science environment (WISE) provides a platform for creating inquiry-based science projects for students to work…

The No Child Left Behind Act is a mandate from the federal government for education to increase student performance and school accountability. As a result of this mandate, many states have issued the use of high-stakes standardized tests as a means of monitoring schools' accountability. New York State administers the English Language Arts (ELA)…

Enculturation is the degree to which a person adheres to the values and behaviors of an indigenous or ethnic culture. This study was conducted to develop the Enculturation Scale for Filipino Americans (ESFA). Items were generated from a literature review, interviews with 5 Filipino American academic experts, and a survey of 24 cultural informants.…

This investigation examined the influence of EFL student teacher self-regulation of learning (SRL) on their curricular content-knowledge and course-design skills. Positivism guided this study at the levels of: ontology (one form of reality); epistemology (detachment from the subjects); and methodology, using nomothetic research strategy (causal…

Development and behavior during the first 2 years of life was assessed retrospectively by the parents to 23 adolescents and young adults with Asperger syndrome and 13 typically developing adolescents and young adults. The groups were matched on chronological age and the participants were within the normal range of intelligence. The questionnaire,…

The GED[R] English as a Second Language (GED ESL) Test was designed to serve as an adjunct to the GED test battery when an examinee takes either the Spanish- or French-language version of the tests. The GED ESL Test is a criterion-referenced, multiple-choice instrument that assesses the functional, English reading skills of adults whose first…
