Factor analysis of the Bell Reality Testing Inventory items produced three subscales interpreted as dimensions of the reality testing ego function: Reality Distortion, Uncertainty of Perception, Hallucinations and Delusions. Replication factor analysis confirmed the factor structure. Subscales appear sensitive to variations in psychopathology and…

Concludes that while the screening test consists of well-designed and carefully standardized items, its overwhelming preponderance of visual-motor tasks minimizes its usefulness in screening for possible school learning problems. Suggests that it might best be used by therapists working with children in treatment facilities that follow a medical…

Employed 479 subjects to develop and initially validate a random response scale for the Child Abuse Potential Inventory. Preliminary norm and reliability estimates are reported. Cross-validation and construct validity data are provided, indicating that the random response scale is stable across groups and can discriminate normal responders from…

Reliability and validity aspects of the Student Developmental Task Inventory-2nd Ed. (SDTI-2) are reported, including test-retest correlations, internal consistency, task-subtask correlations, social desirability effects, and sex differences in responses. (Author/ABB)

Investigated the reliability and validity of the methods used to measure primary versus secondary alcoholism and claimed childhood symptoms of hyperkinesis/minimal brain dysfunction (Hk/MBD) in three separate studies (N=45), (N=53), (N=38). Results supported the Primary/Secondary Classification Questionnaire and the Hk/MBD Childhood Symptoms…

Demonstrated the reliability of the Body Sensations Questionnaire and the Agorophobic Cognitions Questionnaire on two clinical samples (N=175). The instruments fared well on tests of discriminant and construct validity. Concluded that these self-report inventories are useful, inexpensive, and easily scored measures for clinical and research…

In a study involving 50 undergraduate and graduate education students the Attitudes Toward Mainstreaming Scale was found to have a large first factor with adequate reliability. There was a low correlation between knowledge and ATMS scores, although knowledge was more strongly related to classroom acceptance of exceptional students. (CL)

In a study designed to examine the effects of the difference in method of administration of interrater reliability of the Adaptive Behavior Scale, there were no significant differences in reliability coefficients among informants using three administration methods. Levels of agreement apparently differed with the type of behavior being observed.…

Construct validity patterns of test-criteria and item-criteria correlations are shown to be inconsistent across samples. The results of an investigation of construct validity patterns on two published personality scales is presented. (JKS)

The Ross Educational Philosophical Inventory was psychometrically examined through the use of expert judges and factor analysis of a sample of responses to the inventory. Results are negative in general, but moderately positive results were found in relation to two of the four categories of the inventory. (JKS)

A computer program which computes both the interjudge reliability of individual measurements and the extent to which the judges are biased in their ratings vis-a-vis each other is presented. The methods proposed are recommended on the basis of recent developments in statistical research. (Author/JKS)

An Objective Structured Clinical Examination (OSCE) is an assessment approach employed in medical education, in which residents rotate through multiple stations of standardized clinical tasks to evaluate their clinical competence. Because items used to evaluate residents' performance in each OSCE station are linked to the same task and are rated…

This paper provides formulas for expected true-score measures and reliability of binary items as a function of their Rasch difficulty parameters when the trait distribution is normal or logistic. With the proposed formula, one can evaluate the theoretical values of classical reliability indexes for norm-referenced and criterion-referenced…

This Digest presents a discussion of the assumptions of multiple regression that is tailored to the practicing researcher. The focus is on the assumptions of multiple regression that are not robust to violation, and that researchers can deal with if violated. Assumptions of normality, linearity, reliability of measurement, and homoscedasticity are…

This Digest, intended as an instructional aid for beginning research students and a refresher for researchers in the field, identifies key factors that play a critical role in determining the credibility that should be given to a specific research study. The needs for empirical research, randomization and control, and significance testing are…
