This paper uses the concepts of decision reliability and validity to analyze three alternative psychoeducational assessment strategies: multiple gating, template matching, and time-series methods. It argues that relatively little knowledge is gained through analysis of individual scales and assessment technologies without considering the…

Reports on a study of the use of musical scores and rating scales by 80 pianists who listened to 21 trials of solo piano music. Found that the use of musical scores and rating scales did not improve interrater reliability. Discovered that the subjects were less consistent when evaluating slow musical pieces than faster pieces. (CFR)

This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…

Twelve trained observers were randomly assigned to one of two methods of data collection in scoring teacher-student interactions. Results indicated no overall difference in observer accuracy between momentary time sampling and continuous data collection when scoring behaviors that differed along the dimensions of frequency and predictability.…

The Classroom Environment Scale, revised for use in special education classrooms, was administered to students in 79 special education classrooms in 16 residential and day treatment schools. Psychometric analyses showed that seven of the nine aspects of the classroom found in the original scale were reliably reported in special education…

Forty parents of children with autism or pervasive developmental disorder completed the Wing Subgroups Questionnaire, developed for subclassifying children into one of L. Wing's three hypothesized subgroups. Results indicated that the questionnaire has adequate external criterion-referenced validity, with similar subgroup ratings made by…

Two forms of the Battelle Developmental Inventory, intended for use with handicapped and nonhandicapped children ages 0-8, are examined. The instruments measure personal-social, adaptive, motor, communication, and cognitive skills, for use in screening, diagnosis, identification, assessment, and program evaluation. The paper discusses test…

The Luria Nebraska Neuropsychological Battery identifies cognitive deficits and localizes specific brain impairment in individuals age 15 or older. The instrument uses visual stimulus cards and an audiotape to assess performance in such areas as tactile functions, speech, arithmetic, and memory. This paper examines test administration, summation…

The Peabody Individual Achievement Test-Revised offers a standardized assessment of an individual's level of academic performance in reading, mathematics, spelling, written expression, and encyclopedic knowledge. The test is designed as a screening device for students ages 5-18. This paper describes administration, summation of data,…

The Test for Auditory Comprehension of Language-Revised is intended for use with children ages 3-9 as well as with children and adults with certain disabilities. The test's three sections include Word Classes and Relations, Grammatical Morphemes, and Elaborated Sentences. This paper describes the test's administration, scoring, standardization,…

The Woodcock Reading Mastery Tests assess reading ability in individuals from kindergarten to adulthood. The test battery is designed for use in clinical assessment and diagnosis, program planning, student selection and placement, appraisal of student progress, and other uses. This paper describes the test battery's administration, scoring,…

Four approaches to estimating interrater reliability in early childhood special education research are illustrated and compared: correlation, comparison of means, percentage of agreement, and generalizability theory techniques. Generalizability theory techniques are proposed as a method for estimating the amount of variance attributable to…

Ten speech-language pathology students judged five-second audiovisually recorded speech intervals as stuttered or nonstuttered in group and single-subject experiments. Results showed that judgment accuracy tended to increase after training, both for speakers used during the training process and unfamiliar speakers. Slight increases in interjudge…

The "Behavior Problems Inventory" (BPI) is a behavior rating instrument for self-injurious, stereotypic, and aggressive/destructive behavior in mental retardation and other developmental disabilities. Evaluation with 432 residents in a developmental center found the BPI to be a reliable (retest reliability, internal consistency, and…

This study describes and documents reliability reporting practices in dissertation studies that have used the "Behavior Assessment System for Children" (BASC). Only 9 of 106 studies examined reported reliability for subpopulations. The lack of reliability score estimates has implications for use of the BASC to identify culturally diverse…
