Undergraduate Educational Opportunity Program students were given a variety of traditional, cognitive, college achievement predictor measures and the scales of the Study Attitudes and Methods Survey. These measures were then used in a series of regressions to predict measures of college success. (JKS)

A sample of lower middle class eighth grade Brazilian students were rated by their teachers on eleven aptitude factors. The students were also tested on these factors. Results showed teachers to be fairly accurate in their ratings. (JKS)

The interaction of mental ability and of two different instructional methods was investigated for a second grade linear metric curriculum unit. Mental ability was positively correlated with achievement under the guided discovery method, but essentially uncorrelated for the self paced mastery learning method. (Author/JKS)

The relationships between achievement measures and aptitude, sex, and personality traits were explored in a sample of 226 eighth grade students in an upper middle class suburban school. Among other results, sex did not prove to be a significant predictor of achievement. (Author/JKS)

The ability of the Screening Test of Academic Readiness to predict academic achievement was assessed through using two samples of beginning kindergarten pupils from two successive years in a large midwest suburban school district. The test proved to be a fairly effective predictor. (Author/JKS)

For a sample of seven and eight-year old Nigerian elementary pupils, validity coefficients of a modified matrix completion instrument entitled Modified Hall's Matrices, were determined relative to two achievement tests. The coefficients were quite high. (Author/JKS)

A sample of first grade children were pretested with the Stanford Early School Achievement Test and posttested with the Stanford Achievement Test. Results demonstrated moderate validity of theformer for predicting first grade achievement. Prediction was better in verbal achievement than in mathematics achievement. (Author/JKS)

The early development of the Academic Motivations Inventory, a self-report measure of the academic motivations of college students, is described. Validation and reliability studies suggest that, at present, the instrument could be used to assess motivation of a group or class of students, but not yet as individuals. (Author/JKS)

The validity of using seperate male and female scales for measurement of achievement motivation, as A. Mehrabian did, is seriously questioned. A variety of data are presented to support the case made against this practice. nAuthor/JKS)

Two types of test scores were analyzed to examine whether sixty teachers were unable to use Kohlberg's measurement system for determining stages of moral thought because they were stage scoring invalidly on the basis of content. This proved to be the case. (Author/JKS)

The results of initial validity and reliability studies on the Rational Behavior Inventory are presented. The instrument was developed to be used for assessment, treatment planning, and evaluation of clients by counselors who use Rational Emotive Therapy. (Author/JKS)

In the original item factor analysis of the Adjective Check List, evidence was found for seven main factors. In this cross-validation study, five of the seven factors were replicated: social desirability, introversion/extroversion, internal discomfort, cognitive independence, and social attractiveness. Tables with factor loadings are presented.…

The classification of couples' intrapersonal interaction styles assessed in terms of clinical judgment was compared with assessment based on the Pair Attraction Inventory. The degree of agreement was highly significant on five of the seven inventory categories; this was considered to be evidence for the validity of the inventory. (Author/JKS)

The contributions of the Tennessee Self Concept Scale to the understanding of self concept components are discussed. Factor analysis and canonical correlation results indicate that the subscales of the instrument do not contribute much more information than the total score. (Author/JKS)

Test-retest item instability indices for low, middle, and high scores on the Piers-Harris Children's Self-Concept Scale were calculated in order to test the hypothesis that low scores are invalid because of unreliability of responding. The hypothesis was not supported. (Author/JKS)
