Explains and demonstrates a procedure that is commonly used to determine the reliability of a test in such a way that a person who has modest arithmetical skills can carry out the same analysis on a classroom test or examination. (ASK)

Describes results of study of a 45-item scale developed to measure the construct and administered to four separate samples. The Miville-Guzman Universality-Diversity Scale significantly correlated in theoretically predicted ways with measures of racial identity, empathy, health narcissism, feminism, androgyny, homophobia, and dogmatism (the last…

Reports on studies on the development and validation of the Attitudes Regarding Bisexuality Scale (ARBS). In heterosexuals, subscales were strongly related to attitudes toward lesbians and gay men, frequency of religious attendance, political ideology, and prior contact. In lesbians and gay men, subscales correlated with prior experiences and…

Evaluated Angoff ratings from eight different occupational licensing examinations through generalizability theory to estimate the optimal number of raters. Results indicate that approximately 10 to 15 raters is an optimal target range. (SLD)

Investigated the reliability, validity, and practicality of a controlled production measure of vocabulary, consisting of items from five frequency levels and using a completion-item format. Two equivalent test forms were compared. The test was found to be useful in distinguishing between different proficiency groups. (Author/MSE)

Using portfolios for assessment of nursing competence raises issues of ambiguity, confidentiality, and honesty. More research is needed to develop a clear theoretical framework and measures of validity, reliability, and credibility for nursing portfolio assessment. (Contains 29 references.) (SK)

Evaluates the revised editions of the Self-Efficacy Scale for use with children in schools. Addresses the reliability and validity of the two versions of the scale. Proposes counseling interventions to increase student self-efficacy. (Contains 22 references, 1 table, and an appendix.) (GCP)

Research in the field of Computer Supported Collaborative Learning (CSCL) is based on a wide variety of methodologies. In this paper, we focus upon content analysis, which is a technique often used to analyze transcripts of asynchronous, computer mediated discussion groups in formal educational settings. Although this research technique is often…

Quantitative content analysis is increasingly used to surpass surface level analyses in computer-supported collaborative learning (e.g., counting messages), but critical reflection on accepted practice has generally not been reported. A review of CSCL conference proceedings revealed a general vagueness in definitions of units of analysis. In…

Ratings of child involvement in manual-based cognitive-behavioral treatment for anxiety were associated with the absence of primary anxiety diagnosis and reductions in impairment ratings at posttreatment for 59 children with anxiety (ages 8-14 years). Good-to-excellent interrater reliability was established for the independent ratings of 237…

The reliability and validity of the Attachment Q Sort (AQS; Waters & Deane, 1985) was tested in a series of meta-analyses on 139 studies with 13,835 children. The observer AQS security score showed convergent validity with Strange Situation procedure (SSP) security (r=31) and excellent predictive validity with sensitivity measures (r=39). Its…

Reliability is a problem inherent in all educational assessments, but the amount of attention this particular problem should be given is related to the function and use of the assessment. In this article, classification accuracy is put forward as a conceptualization of reliability that is meaningful for a large number of educational assessments.…

The information function is an important statistic in item response theory (IRT) applications. Although the information function is often described as the IRT version of reliability, it differs from the classical notion of reliability from a critical perspective: replication. This article first explores the information function for the…

The authors developed and validated a measure of employees' attitudes toward lateness at work. Analyses provided clear evidence of the reliability and validity of the new measure. Specifically, high reliabilities were observed in both student (a = 0.82) and employee (a = 0.84) samples. Using objective lateness data from organizations, the measure…

The Childhood Asperger Syndrome Test (CAST) is a 37-item parental self-completion questionnaire to screen for autism spectrum conditions in research. Good test accuracy was demonstrated in studies with primary school aged children in mainstream schools. The aim of this study was to investigate the test-retest reliability of the CAST. Parents of…
