Rasch analysis offers researchers an innovative method for developing and validating rehabilitation instruments. Despite the increased use of Rasch analysis by allied health researchers, this method continues to be underutilized by rehabilitation counseling professionals. In the rehabilitation counseling profession, vocational evaluators use…

The present study examined the relation between individual cognitive structure and several key career decision variables. Specifically, in a sample of college students enrolled in a career development class, the usage of the RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) circumplex (adherence) was examined as…

This article details the development of the Critical Processing of Beauty Images Scale (CPBI) and studies demonstrating the psychometric soundness of this measure. The CPBI measures women's tendency to engage in critical processing of media images featuring idealized female beauty. Three subscales were identified using exploratory factor analysis…

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…

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)

Achievement in mathematics is an issue of great concern not only to students and parents but also to employers and researchers in Kenya. This is because the Kenya National Examination Council (KNEC) has continuously reported dismal results in this area, and especially in geometry. Also, KNEC indicates that it presents difficulties to both the…

Successful mentors seem to understand and appreciate their mentees, entering their worlds to uncover their unique strengths and capabilities. This sort of empathy and sensitivity goes a long way toward facilitating close relationships, as does the mentee's willingness to fully engage in the mentoring experience. And, since initial resistances may…

In this study, the authors examined the reliability, structural validity, and concurrent validity of Zimbardo Time Perspective Inventory (ZTPI) scores in a group of 815 academically talented adolescents. Reliability estimates of the purported factors' scores were in the low to moderate range. Exploratory factor analysis supported a five-factor…

The Personality Psychopathology Five (PSY-5) is a model of personality psychopathology assessed in adult populations with a set of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales. The authors examine the reliability and validity of recently developed lower-order facet subscales for each of these five domains, with an emphasis on…

Curriculum-based measurement of oral reading fluency (CBM-R) procedures have been developed to screen and evaluate student performance in reference to local norms and/or benchmarks. Recent changes in federal law have set the stage to use CBM-R data within a response to intervention model to guide high-stakes educational decisions (e.g.,…
