The construct and predictive validity of adaptive behavior was investigated using a multitrait multimethod analysis with 66 mentally retarded institutionalized persons. Adaptive behavior had high convergent validity and low discriminant validity and predicted MA program placement better than did MA, suggesting that adaptive behavior scores could…

Critically examines articles by Goodall and Phillips (EJ 246 871 and 254 905). Argues that science is a part of a critical approach to knowledge and that attempts to divorce science from criticism mystify the reader by misidentifying issues facing the emerging social science of communication. (PD)

Assessed the relative predictive validity of obvious (O), neutral (N), and subtle (S) items of the MMPI MA scale for 86 males. Subtle-obvious ratings were compared to criteria in questionnaire, life-history, and objective tests. Correlations among the criteria were generally insignificant, suggesting that hypomania is not a homogeneous construct.…

Divided the Minnesota Multiphasic Personality Inventory Pd scale into obvious (O), neutral (N), and subtle (S) subscales. Using college students results were: Pd-O scores were the most powerful predictor of criterion; Pd-S scores made a smaller but unique contribution; and Pd-N scores made no contribution not already in Pd-O criterion…

Compared regression lines for prediction of Wide Range Achievement Test scores by Wechsler Intelligence Scale for Children and revised WISC Full Scale IQs across race. Results support the use of a common regression line in the prediction of achievement scores for races. (Author)

The concurrent and predictive validity of the Achievement Anxiety Test (AAT) were investigated. The evidence gives cause to be concerned about the quality of a difference score because of the nonindependence of the two scores. Further, the underlying structure of the instrument appears to be more complex than originally hypothesized. (Author/GK)

The Analysis of Learning Potential was developed to assist counselors and teachers to formulate more realistic academic expectations in view of the pupil's estimated learning potential. Results of the study suggest that the instrument does have the predictive characteristics that might be expected of a general academic aptitude measure. (Author)

Responds to W. S. Cooper's article on utility-theoretic indexing (Journal of the American Society for Information Science, v29 n3) and posits that the method's claim to predictive success rests solely on its appeal to the consequences of decisions. (FM)

Answers Patrick Wilson's criticism of the theory of utility-theoretic indexing (Journal of the American Society for Information Science, v30 n3) and defends the theory on the basis of its analytic capability. (FM)

CUTOFF is a program to identify the most efficient classification prediction cutting score. It ranks the scores of a criterion and a comparison group and organizes them into cumulative frequency tables allowing for immediate display of an index of correct identifications associated with each score.

Research supports previous findings in which situation-specific anxiety trait instruments have been shown to be better predictors of behavior than general anxiety trait instruments or coaches' subjective ratings, and it support the predictive and construct validity of the Sport Competition Anxiety Test (SCAT). (MB)

The Achievement Motivation Scale, a brief, non-theoretical self-report measure, was administered to ten classes of undergraduates at two universities. Results supported other findings suggesting that the scale is useful in predicting college grades even when combined with high school grade point average and a scholastic aptitude test. (Author/JKS)

To be able to conclude anything firm about either a predictor or a criterion from the correlation between the two, a whole range of conditions must be met. Those conditions, which are in effect predictors of validity, are discussed, with the emphasis on the educational situation. (Author)

Compares four closed-formula estimators (Burkett, Claudy, Rozeboom, Browne) and the omit-one method for estimating TRS, the true shrunken correlation (not to be confused with TR, the true multiple correlation). Recommendations are based on artificial populations with known TRS. (Author/SV)
