The structure and item performance of the Myers-Briggs Type Indicator was investigated using data from 39 college students. Factor analysis was applied to the items, factor adequacy and invariance coefficients were computed, and the appropriateness of the recommended item weights was examined. Results strongly supported the instrument's construct…

The Learning Style Inventory (LSI) and the newly revised Learning Style Inventory (LSI II) were examined for internal consistency, test-retest reliability, and stability of the four classifications resulting from their scores. Internal consistency was improved in LSI II, but problems with low test-retest indices and classifications stability…

The underlying structure of ratings of clinical competence was investigated. The instrument consisted of 33 statements on clinical behavior filled out by directors of medical education programs at postgraduate training institutions. It was concluded that ratings of clinical competence represent a multidimensional construct involving at least three…

This study examined the reliability of holistic scoring for a sample of essays written during the Spring 1985 MCAT administration. Analysis of variance techniques was used to estimate the reliability of scoring and to partition score variance into that due to level differences between papers and to context-specific factors. (Author/LMO)

This study analyzed the internal consistency and factorial composition of the Job Stress Questionnaire (JSQ) and compared its factor structure across three occupational groups as well. The results indicated acceptable reliabilities for three of four subscales while factor analysis revealed limited support for the factorial validity of the…

The interrelationships among halo and leniency rating errors were examined using simulated rating data. As leniency increased, halo decreased when measured by dimension intercorrelations but increased when measured by standard deviations across dimensions. Implications of these results for the use of the various measures are discussed. (SLD)

Test-retest reliability of the Q-Sort Inventory of Parenting Behaviors was obtained with a sample of 30 mothers of 3-year-olds. The within-subject correlation, with 2 weeks between test administrations, for sorting the test statements was 0.72. Reliable differences among the respondents were responsible for 35% of the variance. (SLD)

An experimental test was developed for the measurement of self-concept in an employment setting. Administering this six-factor Dimensions of Self-Concept test to 201 employees in an electronics/computer company resulted in a determination of internal consistency and reliability sufficient to justify testing a revised version based on statistical…

A total of 152 first- and second-year undergraduates rated the effectiveness of their lecturers using three response formats. A scale on which each point gave a precise percentage label was more accurate than one with all points verbally labeled or with only the end points labeled. (SLD)

The impact of overall test length and difficulty on the expert judgments of item performance by the Nedelsky method were studied. Five university-level instructors predicting the performance of minimally competent candidates on a mathematics examination were fairly consistent in their assessments regardless of length or difficulty of the test.…

Levine's equations for random groups and unequally reliable tests can be used to equate two tests through performance on an anchor test. Levine's assumption of a parallelism requirement is not necessary; it is sufficient to assume only that the tests are congeneric, an assumption implicit in linear test equating. (SLD)

Differences between recommended sets of equal-interval response anchors derived from scaling techniques using magnitude estimations and Thurstone Case III pair-comparison treatment of complete ranks were compared. Differences in results for 205 undergraduates reflected differences in the samples as well as in the tasks and computational…

Research with 38 undergraduates studied a technique for assessing conformity on a ratio scale and variables used to analyze normative and information factors. Computer presentation of the statistics and storage of responses allows assessment of discrepancies between actual line length and length of the reproductions made with/without peer…

With bootstrap methodology, the stability of the Angoff delta item bias index was investigated. Data from item responses of 400 Black and 400 White fifth-grade students taking the Iowa Tests of Basic Skills indicated that the Angoff delta statistic had only moderate stability. (SLD)

A Monte Carlo simulation was used to investigate the effect of data transformation on average correlations between Job Descriptive Index scores. In general, results indicate that transformation of scores did not result in marked changes in the correlations and that such transformation may not be worthwhile. (SLD)
