The Piagetian developmental stage of concrete operational thought and the theoretical groupement structures underlying children's performance of 12 concrete operations tasks are discussed. Tasks were shown to develop in five related sets. Three factor structures were found in this longitudinal study. (Author/CM)

For a sample of student clients who judged the effectiveness of their counselors in a university counseling and testing center on a modified form of the Evaluation of Counselors Scale (EOC), a factor analysis of the intercorrelations of student responses to 19 items provided four orthogonal dimensions.

Reliability, factorial complexity, and predictive validity of the Test of Syntactic Abilities Screening Test were determined from the responses of mildly hearing impaired, severely hearing impaired, and profoundly deaf students. Results showed that the test was unifactorial. Use of the total score to discriminate among students is justified.…

Identified criterion variables known to be related to educational-vocational indecision. Determined if unique relationships existed between factor structure on the Career Decision Scale (CDS) adapted for graduate students and the criterion variables. Results suggested that factor scores of the CDS measure essentially equivalent components of…

The "factor" analyses published by Schultz, Kaye, and Hoyer (1980) confused component and factor analysis and led to unwarranted conclusions. The principal factors method yields two factors which support the a priori expectation of a difference between intelligence tasks and spontaneous flexibility tasks. (Author/RD)

A hierarchical factor solution was obtained from a psychometrized battery of Piagetian-type tasks individually administered to 660 kindergarten children. The first two levels of factors included Piagetian theoretical entities. A third level factor was identified as a g. The association of Piagetian tasks with academic achievement was through the g…

Compared two behavioral treatments for marital discord with a nonspecific control and waiting-list control. Behavioral treatments combined problem-solving skills with contingency management procedures, differing only in contracting form, good faith contracts, and quid pro quo contracts. Both behavioral groups improved significantly more than…

Investigators are urged to plan factor analytic studies prior to collecting the data, to formulate a hypothesized factor structure, to develop several relatively pure measures of each factor expected, and to select an appropriate sample of at least 200 cases. Continuous variables should be used rather than dichotomous variables. (Author)

In a Monte Carlo simulation, a methodology was developed to investigate the existence of radex properties among objective test items. In an experiment with items covering four categories of Bloom's cognitive domain taxonomy, the items did not have the factorial properties of a radex with four levels of complexity. (Author/BW)

The Wechsler Intelligence Scale for Children--Revised was administered to 946 intellectually gifted students, 6 to 16 years old. The factor structure was remarkably similar to that reported for previously studied groups, thus supporting the test's validity. (Author/GDC)

Study investigated whether instruments assessing the sociopsychological climate of classrooms were appropriate from the students' perspective. The Classroom Environment Scale was administered to 185 high school students. Results indicated that students' importance ratings of sociopsychological climate structures validated a three- dimensiona1…

Data from 182 teachers showed the Educational Attitude Survey to be a factorially valid and highly reliable measure. Its 16 items yield three scores: administrative aspects of mainstreaming, educational aspects, and total score. (Author/CP)

The reliability of the four-factor model of the survey of study habits and attitudes (SSHA) was investigated. The reliabilities of the scales were marginal as measured by coefficient alpha. The hierarchical model of the SSHA was not supported by confirmatory factor analysis. (Author/BW)

Reviews literature on the relationship between psychosocial events and dying and death from a behavioral perspective. Individual control has a part in the relationship between the timing of death and psychosocial factors. It is argued that behavioral self-management is a useful therapeutic tool for working with clients nearing death. (Author/BEF)

Factorial modeling is justified as a method for analyzing correlations in support of causal inference. The method is illustrated and compared to path analysis, LISREL-type analysis, canonical correlation, and commonality analysis. Predictions of impacts of policy manipulations are demonstrated.
