The suggestion that multiple-choice items can be converted to true-false items without essentially changing what the item measures and with possible improvement in efficiency is investigated. Each of the 90 four-choice items in a natural science test was rewritten into a pair of true-false items, one true, one false. The resulting 180 items were…

Male and female enlistee samples were compared for total groups and by enlistment region in terms of their performance on the Airman Qualifying Examination (AQE) and the Armed Services Vocational Aptitude Battery (ASVAB). Women in the Air Force (WAF) test-retest performance was evaluated on the Armed Forces Women's Selection Test (AFWST) which is…

Research to date on adaptive (sequential, branched, individualized, tailored, programmed, response-contingent) ability testing is reviewed and summarized, following a brief review of problems inherent in conventional individual and group approaches to ability measurement. Research reviewed includes empirical, simulation and theoretical studies of…

The present study was concerned with several currently unanswered questions, two of which are: what is an empirically determined ratio of multiple choice to equivalent true-false items which can be answered in a given amount of time?; and for achievement test items administered within a classroom situation, which of the two formats under…

Investigated construct validity of four self-report, self-concept instruments: Bledsoe Self-Concept Scale (BSCS), Children's Self-Concept Scale (CSCS), Self-Esteem Inventory (SEI) and Purdue Self-Concept Scale (PSCS). In assessing the self-concepts of 175 fourth-grade children convergent validity of the tests was not established. (Author)

Studies of the reliability, normative data, construct validity, and concurrent validity of the Social Perception Behavior Rating Scale used with mildly learning-disabled, behavior-disordered, and nondisabled children indicated adequate reliability, marked differences in scores of handicapped and nonhandicapped children, and a logical pattern of…

Examines the interclass and intraclass reliability of three published informal reading inventories and their alternate forms and concludes that though acceptable, the reliabilities of the inventories suggest the need for cautious interpretation. (HOD)

Examined the scale characteristics of two measures of organizational commitment. Using data from l,l05 accountants, findings indicated that while both instruments exhibited a high degree of internal reliability, the Porter et al. (1947) instrument exhibited significantly greater predictive validity with respect to intended turnover than the…

Achievement test reliability and validity as a function of ability were determined for multiple sections of a large undergraduate French class. Results did not support previous arguments that decreasing the number of options results in a more efficient test for high-level examinees, but less efficient for low-level examinees. (Author/GK)

Evaluated the reliability and validity of objective scoring procedures on the Draw-A-Person Test. Subjects were mentally retarded persons, psychotics, and normals. Reliability estimates for both scales ranged from .42 to .78. Positive evidence indicates that overall quality does relate to overall level of psychological adjustment. (Author)

Single administration (beta-binomial) estimates for the raw agreement index p and the corrected-for-chance kappa index in mastery testing are compared with those based on two test administrations in terms of estimation bias and sampling variability. Bias is about 2.5 percent for p and 10 percent for kappa. (Author/RL)

Compared Kuder-Richardson Formula 20 and coefficient alpha (by blocks) reliability estimates for a reading comprehension test. On the average, K-R 20 exceeded coefficient alpha by about .05; that is, K-R 20 exaggerated the internal consistency of the test as would be expected from theory. Implications for counseling interpretations are discussed.…

A study of Scholastic Aptitude Test scores for nine groups of students with disabilities taking special test administrations found differences in score levels among disability groups but no significant differences of measurement precision and no evidence of disadvantage for disabled students. (Author/MSE)

The psychometric integrity of a short form of the Questionnaire on Resources and Stress was evaluated, based on data provided by 66 mothers and 66 fathers of 33 handicapped and 33 nonhandicapped preschool children. Alpha reliability, factor structure, and construct validity analyses indicated that the measure has reasonable psychometric integrity.…
