Investigates the short-term stability of the Adjustment Scales for Children and Adolescents for 124 randomly selected children in grades kindergarten to grade 12. Significant test-retest stability coefficients were obtained and mean differences across the retest interval did not exceed .8 raw score points. Results were similar to those obtained in…

Two studies are reported demonstrating the reliability, validity, and clinical utility of the Language Development Survey (LDS) as a screening tool for the identification of expressive language delay in toddlers. The LDS test-retest reliability was .97. The LDS also correlated highly with other measures and the LDS identified at-risk group scored…

Undergraduate psychology examinations from 48 schools were analyzed to determine the proportion of items at each level of Bloom's Taxonomy, item format, and test length. Analyses indicated significant relationships between item complexity and test length even when taking format into account. Use of higher items may be related to shorter tests,…

States that standard scores are the numerical universal language for reporting and comparisons. Discusses what standard scores are, specifically, and why they are used, along with how the conversion assessment of raw scores to standard scores is accomplished. Provides contact information for those who would like to further their knowledge on the…

Simulations were used to compare the moderator variable detection capabilities of moderated multiple regression (MMR) and errors-in-variables regression (EIVR). Findings show that EIVR estimates are superior for large samples, but that MMR is better when reliabilities or sample sizes are low. (SLD)

The extent to which testing practices complied with professional guidelines regarding reliability and validity evidence was studied in research appearing in American Psychological Association journals. Documentation of reliability and validity was reported for 20% of the 2,157 instruments studied in these papers. About half supported one or the…

Reports on the development of the Hebrew language translation of the Bath County Computer Attitude Scale among a sample of 339 undergraduate students in Israel. The data support the reliability and validity based on frequency, correlation, reliability, and factor routines analyzed with the SPSS (Statistical Package for the Social Sciences).…

This study compared fears and social anxiety in children with (n=57)and without (n=25) developmental disabilities, using self-ratings and parent ratings. Children without disabilities showed significantly higher consistency over time than children with disabilities. Correlations between parent and child ratings were fair to good. (DB)

Reports on a study of 14-15 year old students' ideas about combustion. Describes patterns of students' explanations across a range of questions and analyzes them to gain insight into both the degree of consistency of their explanations and how this may affect the process of conceptual change in the students. (Contains 35 references.) (Author/YDS)

Adventure education research struggles to measure components of the field's larger, complex processes and outcomes. Because valid measures provide the foundation of quantitative research, finding, assessing, and utilizing good measures of the outcomes and processes of adventure education are necessary. Describes measurement techniques, validity,…

Reports on the design and development of the Parent Concerns Questionnaire, an instrument designed to obtain the views of mothers in general, and particularly depressed mothers, in families subject to child and family care intervention. Discusses the reliability and validity of the instrument. (JPB)

This article critiques the research methodology used by Mudford, Hogg, and Roberts (1999) that resulted in a failure to achieve inter-observer agreement on adults with mental retardation when using an experimental, 13-category behavior state code. Arguments are provided on why their videotape study does not meet requirements of acceptable…

Describes five basic elements that need to be considered with every test: backwash; reliability, administrative concerns; validity; and ethics. These elements are discussed in relation to tests for students who are second language learners of English. (Author/VWL)

Describes development and testing of the Literacy Orientation Survey (LOS)--an instrument for assessing teachers' beliefs about literacy learning and classroom practices as related to constructivism. Finds while LOS has robust internal validity and reliability, questions remain about external validity of teachers' self-reports of their…

Analyzed data from a session of the General Certificate of Secondary Education (GCSE) mathematics examination to identify items displaying a bi-modal expected score distribution, try to explain the bi-modality, rescore the items to remove under-used middle categories, and determine the effect on test reliability of rescoring the data. Discusses…
