Breast cancer is the most common cancer among women in North Africa. Women in this region have unique reproductive profiles. It is essential to obtain reliable information on reproductive histories to help better understand the relationship between reductive health and breast cancer. We tested the reliability of a reproductive history-based…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

This paper reports on the development of a scale for determining the quality of the student e-learning experience at the degree level when the student learning context is predominately a campus-based experience. Rapid developments in the use of information and communication technologies (ICT) in higher education require methods for evaluating the…

This paper reports on evaluations of a projective measure of self-esteem adapted from the Tasks of Emotional Development (TED). The evaluations were conducted in 7 studies with a total sample of 416 children and adults. The revised TED uses a five-point scoring system ranging from negative to positive self-esteem. Interrater reliability in the…

The Client Observation Checklist (COC) was developed to evaluate Project ADAPT's intervention in three behavioral areas: bathing; dressing; and socialization. Project ADAPT is designed to provide services to meet the needs of chronically mentally ill residents of nursing homes. Specifically, the project provides staff trained to work with the…

A prototype low inference observation instrument to measure minimal teaching competencies of teaching candidates was deductively developed. Focus is on determining if observers could be trained to use the observation instrument with a high degree of reliability and validity. The instrument, entitled Classroom Observation and Assessment Scale for…

This paper describes the Measure of Epistemological Reflection (MER), an instrument to assess cognitive developmental level according to the Perry scheme of intellectual and ethical development. It contains sets of questions for each of the six cognitive domains: decision making, learner role, instructor role in the learning process, peer role in…

The purpose of this study was to further examine the reliability of the Peabody Picture Vocabulary Test (PPVT), a new instrument to measure hearing vocabulary so that a student's verbal intelligence may be inferred. A group testing procedure was utilized by reproducing the PPVT plates on 35 millimeter transparent slides and projecting them onto a…

The assumptions of the classical test-theory model are used to develop a theory of reliability for criterion-referenced measures which parallels that for norm-referenced measures. It is shown that the Spearman-Brown formula holds for criterion-referenced measures and that the criterion-referenced reliability coefficient can be used to correct…

The usefulness of generalizability theory in assessing the reliability of classroom observation instruments is illustrated, with a new index of reliability, called the coefficient of generalizability, given as an index of how well one can generalize from the instrument to the universe score according to the conditions of observation. Data from an…

This study examined how local content specialists performed when applying the Angoff and Nedelsky standard setting procedures to objective-referenced instruments in reading and mathematics. Results revealed several differences between the standard setting procedures in terms of both level and consistency of the cut scores generated. (Author/BW)

Procedures are described for studying the reliability of decisions based on specific passing scores with tests made up of discrete items and designed to measure continuous rather than categorical traits. These procedures are based on the estimation of the joint distribution of true scores and observed scores. (CTM)

A longitudinal study of approximately 1,000 students aged 10-16 showed high stability of intelligence and creativity. Stability coefficients for intelligence were higher than those for creativity. Results supported the construct validity of creativity. (MH)

Development of the Stereotyped Behavior Scale for adolescents and adults with mental retardation is described. Use with 600 individuals resulted in refinement and a 26-item scale with an internal consistency alpha of 0.88, test-retest reliability of p=0.90, and interrater reliability of p=0.76. (DB)

Purpose: The purpose of this study was to examine the test-retest and inter-rater reliability of a measure of muscle extensibility developed by Tardieu, de la Tour, Bret, and Tardieu (1982) in fullterm and preterm newborns. Method: Twenty-one fullterm infants and twenty preterm infants were examined by two physical therapists. Each physical…
