Findings suggest that a woman will obtain a different Holland code depending on what instrument or what set of scales within an instrument is used to establish that code. This phenomenon could reflect sample characteristics equally as much as any bias in the measures. (Author)

Activity level was measured by two independent methods, a mechanical recording device and teacher descriptions, in a sample of 129 children (65 boys and 64 girls), participating in an ongoing longitudinal study. (Author/MP)

A chain of lower bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted scores (such as a test). Algorithms for obtaining various reliability coefficients are presented. (Author/JKS)

To assess the stability of the factor structure of the Instructional Improvement Questionnaire (IIQ), factor analyses were run for 1973, 1974, and 1975 results, partialling out three variables: expected grade, percent taking the course as an elective, and student's year. The factors were stable over the three years. (Author/BW)

Increasingly, appeals to the divorce statistic are employed to substantiate claims that the family is in a state of breakdown and marriage is passe. This article contains a consideration of reasons why the divorce statistics are invalid and/or unreliable as indicators of the present state of marriage and family. (Author)

Describes the procedures the authors of the System for Career Decision-Making (CDM) followed in establishing client scoring reliability. Authors recommend that manuals of self-scored inventories provide data establishing scorer reliability, that scoring be supervised, and that APGA test standards deal directly with scorer reliability. (Author)

The purpose of this study was to investigate the structure of motor proficiency in a sample of 765 children between the ages of 4 1/2 to 14 1/2 years. The study was conducted as one aspect of the standardization of a motor proficiency scale, the Bruininks-Oseretsky Test of Motor Proficiency. (Author/SJL)

Investigations of item bias provide an empirical basis for the identification and elimination of items appearing to measure different traits across population/culture groups. This paper reviews the psychometric rationales of six types of approaches to biased item identification. (Author/JKS)

Criterion-referencing is a way to enhance the interpretation of test scores by referencing them to well-defined behavior domains. Behavior domains may be ordered or unordered; several varieties of criterion-referenced tests within each of these types are discussed. (Author/RL)

Because educational researchers are becoming interested in the uses of ethnographic field methods, the author examines some of the theoretical disputes and methodological problems being experienced in contemporary anthropology, such as hypothesis testing, observer bias, and reliability. (Part of a theme issue on anthropology of education.) (SJL)

Six physical education specialists were asked to rate their second, fourth, and sixth grade students on physical performance, peer relations, cooperative behavior, and ability to reason. When the ratings were repeated eight weeks later, a high degree of stability was found across the four variables and for all three grades. (Author/SJL)

Critiques two central issues of measurement as applied to the evaluation of student progress in cooperative education: reliability and validity. Urges the synthesis of measurement and professional judgment in all phases of the evaluation process. (SK)

An empirically developed infant and preschool reinforcement survey was completed by 35 parents and 21 children. Test-retest coefficients were computed on these data after a one-week interval. The development of the survey, as well as its usefulness for school psychologists, is described. Survey is appended. (Author)

Integrates a review of Rotter's theory with an analysis of the design and development of locus of control scales, and tests the reliability and validity of an abbreviated version of Rotter's Locus of Control Scale which provides practitioners with an instrument less confusing than other locus of control scales. (Author)

Research in written composition must not only face up to the fact that composition tests must meet the same requirements for validity and reliability that other tests must meet, but it also faces the unique difficulty of figuring out a way to give a valid and reliable pretest. (DD)
