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…

Evaluated two alternate forms of self-report measurements of Africentrism defined as the degree to which a person adheres to the Nguzo Saba (Seven Principles) in African and AfricanAmerican culture. Four reliability and validity studies reveal a 15-item version that can be used for future testing and for properly directing use of African-centered…

Using feminist theory about the social construction of the female body, a scale was developed and validated to measure objectified body consciousness in young women (n=502) and middle-age women (n=151) using surveillance, body shame, and appearance control beliefs. The three scales were demonstrated to be distinct dimensions with acceptable…

Three methods based on the nonparametric item response theory (IRT) of R. J. Mokken for the estimation of the reliability of single dichotomous test items are discussed. Analytical and Monte Carlo studies show that one method, designated "MS," is superior because of smaller bias and smaller sampling variance. (SLD)

Study examines the reliability and validity of the Instructional Climate Survey-Form S (ICI-S), a 20-item instrument that measures school climate, administered to students (N=328) in three programs. Analysis indicates that ICI-S was best explained by one factor. Reliability coeffecients of the total score were within the acceptable range for all…

Discusses the validity and reliability of teacher observation in gifted child research. The benefits of teacher observation include an increase in professional authority and self-consciousness of teachers, an enrichment of the quality of relationships between teachers and parents of gifted students, and a revelation of the educational needs of…

Examined low interrater agreement by decomposing common and unique variance among parent, adolescent, and observer reports of parental warmth and negativity into genetic and environmental factors. Model-fitting analyses findings generally supported predictions for warmth and negativity at Family and Individual levels. At the Social level, genetic…

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…

Two studies on young children are reported that address the psychometric characteristics of the Scale for Assessing Emotional Disturbance (SAED). Results from the studies indicate that the SAED is a reliable and valid instrument for identifying young children who may qualify for the federal definition of emotional disturbance. (Contains…

Examined development of child and adolescent self-concept in two overlapping age cohorts as a function of the self-concept domain, social/developmental/educational transitions, and gender. Structural equation modeling addressed questions about stability of individual differences over time. Multilevel modeling addressed questions about mean-level…

This article comments on results of a study (EC 629 869) on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It discusses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains…

This article responds to comments (EC 629 869-70) on a study on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It addresses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains 6…

Two studies compared multidimensional self-concept measures in preadolescents. Findings indicated that the Self-Description Questionnaire and Self-Perception Profile for Children were highly correlated and comparable in reliability, stability, subscale interrelations, and associations with others' evaluations. Correspondence among various…

Studied the psychometric properties of the Six-Factor Self-Concept Scale (J. Stake, 1994) in a sample of 185 racial/ethnic minority college women. Results support the reliability and construct validity of the subscale scores of the instrument and the potential usefulness of the scale for studying ethnic and cultural differences. (SLD)

Developed a procedure for defining achievement levels on continuous scales using aspects of Guttman scaling (L. Guttman, 1950) and Item Response Theory. Using data from high school mathematics tests for about 6,000 students, found the new procedure to have higher reliability, higher classification consistency, and lower classification error than…
