The author responding to criticism of an earlier article attempts to clarify his previous remarks on the reliability and validity of measures of body image in mentally handicapped persons. (LC)

An experimental test on beam walking (for balance), administered to 189 minimally brain injured and 226 educable mentally retarded (EMR) 8- to 13-year-old children, yielded results such as reliability estimates for the mean of three trials were high and there was greater performance reliability for EMR children.

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. (Author)

The goal of this investigation was to derive a common battery of tests for both whites and negroes, and utilizing, if possible, uniform selection standards. (Author)

Both criterion-referenced testing and behavioral assessment share the basic assumption that test behavior is a sample rather than a sign. In addition, both types of assessment focus on response capabilities and performance in specified content domains. Although content validity has been traditionally recognized as essential to criterion-referenced…

One of the most persistent problems in the use of projective techniques is the need to develop objective, reliable and valid scoring systems. The sample consisted of 100 college students enrolled in an introductory psychology course. Ss were administered the DAPIR along with an extensive biographical questionnaire. Additionally, Ss were rated by…

The reliability and validity of the Modified Component Disability Checklist were examined with five secondary learning disabled (LD) teachers, 21 low achieving students, and 21 LD students in grades 7, 8, and 9. During Phase I, teachers matched the component disability to the target behavior; and in Phase II teachers were told to judge each target…

Using data from a National Child Development Study (NCDS) in Great Britain, the applications of instrumental variable methods and structural equation models to estimating instrumental variables are presented. A subset of the longitudinal educational and home background data on children born in England, Wales and Scotland in a March week of 1958 is…

The Feldt-Gilmer congeneric reliability coefficients make it possible to estimate the reliability of a test composed of parts of unequal, unknown length. The approximate standard errors of the Feldt-Gilmer coefficients are derived via a method using the multivariate Taylor's expansion. Monte Carlo simulation is employed to corroborate the…

Marcia's adolescent identity status interview combines objective scoring with a clinical approach to investigate Erikson's theory in terms of the identity crisis of adolescence. Marcia's interview was extended to adult identity processes by redefining the crisis and commitment dimensions of strength (of involvement in work) and flexibility (of…

The concept of social role range (SRR) deals with the magnitude of an individual's repertoire of different interpersonal behavior patterns and exhibits the properties of a personality trait. Over a broad range of interpersonal settings, individuals tend to be consistent in the magnitude of their SRR's. A role play technique was devised for…
