The findings and conclusions from research on predictive validity among markedly different groups are discussed. Empirical findings using the regression line neither support nor contradict the existence of bias or the hypothesis of differential validity. Conclusions drawn from the research are questionable. Elimination of bias in a test, contrary…

The purpose of this study was to test the predictive validity of the Ramak--a vocational interest inventory based on Roe's (1956) classification of occupations. In this follow-up, 81 percent of the original sample, tested 7 years earlier, was located. The effectiveness of the Ramak in vocational counseling is evaluated. (Author)

Predictive validity of the Differential Aptitude Test (DAT) was investigated by comparing the DAT scores obtained by students in Grade 9 against their achievement in Grade 12 departmental examinations. Results indicated that the DAT has good predictive power and can be used effectively on a selective basis for counseling and predictive purposes in…

The SVIB for men profiles of 202 male and female counselor education students were examined to determine the extent of sex differences. The differential predictive validity of the SVIB was also studies. The results of this study support the direction which the new Strong is to take. (Author)

MMPI values were used to find the relationship of field dependency to personality traits and styles of pathological adjustment in psychiatric outpatients. The investigation had separate analyses for the patient's sex and found it an important variable in predicting the relationship between test score and dependency and adjustment. (ED)

This study formulated a multivariate model of early infant competence from variables representing a transactional perspective of developing competence in early infancy. The measures used in the competence model were: birth weight; habituation index; personality ratings of the infants' social orientation and task orientation; ratings of maternal…

The validity of some theoretically derived vocational diagnostic signs was examined to learn if a person's self-knowledge, occupational knowledge, and decision-making ability were predictable. The positive results imply some practical applications and the need for further theoretical investigation. (Author)

Generalizations which should be considered when assessing professional readiness are: (1) definitions of effective practice should emphasize discrete behaviors and characteristics, (2) measures of these characteristics should be similar to their criteria, (3) multiple assessment devices should be used, and (4) data used for decision making should…

Validity of selected cognitive and affective variables as predictors of academic success among disadvantaged minority college students was analyzed via multiple regression. The best combination of predictors was reading, attitude toward authority, internality-externality (selected items), and dogmatism, which together accounted for approximately…

This article compared the concurrent predictive accuracy of the (SVIB) for the same subjects on three sets of scales, the SVIB-Holland scales, the Basic Interest scales, and the Occupational scales. (Author)

In Fall 1971, three tests were administered to new students at the American University of Beirut. The predictive validity of each of these tests and of weighted combinations of them with GPA and performance in selected courses as criteria are investigated. (RC)

Provides an estimate of the number of credit hours likely to be earned if college freshmen took the College-Level Examination Program General Examinations (CLEP) and ascertains degree of relationships of scores on each of two CLEP subtests, of performance on an end-of-year achievement test, and of standing on a placement test administered prior to…

For a sample of 325 students enrolled in freshman chemistry, it was found that performance on the Verbal and Mathematics Sections of the Scholastic Aptitude Test of the College Entrance Examination Board exhibited low preditive validity in relation to a criterion of grades in freshmen chemistry.
