A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…

Description of study to determine the impact of management training on student performance focuses on the need for proper evaluation. Pre- and posttraining evaluative tools for rating managers are described, differences in ratings are analyzed, and implications for evaluating management training on interpersonal skills are discussed.

A study that found a low relationship between state regulation and four measures of quality and success is described. The data suggest that the influences of financial and academic flexibility are statistically overwhelmed by other variables, expecially the relative generosity of state funding. (Author/MLW)

Critics have occasionally asserted that the number of factors in the 16PF tests is too large. This study discusses factor-analytic methodology and reviews more than 50 studies in the field. It concludes that the number of important primaries encapsulated in the series is no fewer than the stated number. (Author/JAZ)

Confirmatory factor analyses were used to evaluate the fit of four factor models to high school students' responses to Paivio's Individual Differences Questionnaire (IDQ). Results showed that the IDQ's structure is best represented by a multifactor, oblique model and that five of the factors identified by Paivio can be replicated using a 34-item…

A scale developed to aid in investigation of students' perceived control at school is described, and data on its reliability, validity, and factor structure are reported. Findings reported indicate the usefulness of the perceived control scale by summarizing data from several studies. (Author/LMO)

Three frequently used response formats are compared via analysis of covariance structures. The cumulative results based on four data sets provided evidence inconsistent with previous research suggesting that these formats are interchangeable. The semantic-differential format is most preferred while in most cases the Stapel format is least…

The factorial structure of the Rotter Internal-External (IE) scale was examined. While there was strong evidence against the unidimensionality of the Rotter scale, the findings suggested that the first-order factors do define a single higher-order construct that may represent the generalized IE construct. (Author/LMO)

An instrument for assessing client expectations was analyzed for factors. Four factors emerged, each representing a separate domain of personal problems: Performance Anxiety Problems, Interpersonal Problems, Intrapersonal Problems, and Substance Abuse Problems. Applications of these findings are described in this article. (Author/KS)

An information-processing model of the rating process was proposed and tested by asking 18 teachers to rate 16 hypothetical student profiles formed by systematically varying information along six different dimensions. Findings revealed possible biases in teacher's ratings and indicated the importance of a theoretical model of the rating process.…

Factor analyses of the Kaufman Assessment Battery for Children (K-ABC) were performed on separate groups of Anglo (n=100) and Mexican-American (n=100) fifth-grade children to determine the comparability of underlying structures and to examine the existence of possible bias in construct validity of the K-ABC for each group. (Author/LMO)

This study identified dimensions of classroom control derived from factor analysis of selected classroom process variables, interpreted these dimensions in relation to two contemporary models of classroom control, and explored the relationships between dimensions of control and certain cognitive and affective outcomes. (Author/LMO)

Results of factor and correlational analyses of the Ethical Behavior Rating Scale (EBRS) are reported. The test-retest method and internal consistency estimates yielded reliability coefficients. Construct validity was determined by correlating the EBRS with items from the Ethical Reasoning Inventory. The EBRS reflects the behavioral aspects of…

This paper examines the construct generality of five self-report measures of anxiety across male and female samples, and illustrates the use of confirmatory maximum likelihood techniques for examining factorial invariance. (Author/BW)

Addresses applications of the coefficient of variation as a measure of educational inequality or as a means of measuring changes of inequality status. Suggests the Gini coefficient has many advantages over the coefficient of variation since it can be used with the Lorenz curve (Lorenz provides detail Gini omits). (BRR)
