Objectives: Mental health organizations are strongly encouraged to implement empirically supported treatments (ESTs); however, little is known about their working environments. The present study investigated how provider demographics, workplace environment, and whether ESTs were used affected the worker morale. Method: Frontline workers…

Although literature about problem based learning (PBL) is not scarce, there is little research on experiences about learning methodologies that combine PBL and the use of simulation tools. This lack of studies is even more notable in the case of engineering courses. The motivation for this study is to show how such a combination of PBL and…

Assuming a multiple linear regression model with q independent variables, a procedure is developed for determining the minimum statistically significant increase in the multiple correlation coefficient when an additional independent variable is considered for regression. The procedure is presented analytically and in table form. Examples are…

It is the purpose of this paper to investigate the chance nature of overfit as it relates to a regression formulation of research, to describe a model for projecting the overfit, and to empirically validate the model. (Author)

The present study is the first phase of a longitudinal investigation designed to isolate non-intellective factors which might increase the power to predict academic success. (Author/RK)

Fifth- and eleventh-grade males and females who knew each other ( knowers'') judged classmates' photographs on physical attractiveness, perceived attitude similarity, and interpersonal attraction. Nonknowers'' (male and female classmates in different schools in the same grades) judged the same photographs on physical attractiveness. (Editor)

Article is concerned with a model for school system evaluation. The usefulness of the indices from this model depend on their stability, and this study presents evidence related to their stability when pupils and factors related to time are considered as sources of error. (Author/RK)

This study investigated the relationship between collective negotiations and teacher salaries in Wisconsin public school districts. Data were collected from a random sample of 324 Wisconsin school districts with professional staffs ranging from 30 to 500 members. A six-indicator index was developed to measure the comprehensiveness of collective…

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

Scores on the Junior Eysenck Personality Inventory of some 2,000 white, Negro, and Mexican-American school children, ages 9 to 13, were examined in relation to measures of intelligence and home environment as predictors of scholastic achievement. (Editor)

Explores the effects of task characteristics and structural characteristics on aspects of information processing based on a survey of employees in the Australian telecommunications industry. Relevant research is reviewed; the analysis of results is explained; and implications for organizations are suggested. (Contains 42 references.) (LRW)

The development of a scale for measuring the interaction of Mexican Americans with Anglos (Anglo Interaction Index) was discussed. The scale was part of a larger investigation on status mobility among middle-class Mexican Americans in Texas. Data was collected in Waco (selected for pretesting), Austin, McAllen, and Lubbock. These communities were…

This paper is an extended series of appendices to the report "Exploring the T.R.Q.: An Assessment of the Effectiveness of the Teachers' Rating Questionnaire," Report Number 123. It should be most useful to those familiar with multiple regression analysis and factor analysis and wishing a more complex record of the statistical procedures…

A study investigating variables in Canadian Chief Executive Officers' use of information sources to scan external business environments is reported. Findings show that frequency of source use correlates to perceived uncertainty and that source quality is more important than source accessibility--a finding that contradicts past user studies. (28…

The accuracy with which regression models estimate treatment effects is dependent upon a number of conditions. The stability of the regression line (a function of sample size and correlation between pretest and posttest) is said to be the most important of these conditions. The utility of regression models is proportional to the size of the…
