A Monte Carlo Study of Constrained Factor Analysis Using Maximum Likelihood and Unweighted Least Squares
From each of 105 samples of 300 observations each and from each of 87 samples of 3,000 each, constrained factor analyses of 96 normally distributed variables arranged in a three-stage hierarchical structure were computed by maximum likelihood (ML) and unweighted least squares (ULS). It was evident that ULS not only takes less time and computer resources than does ML, but also leads to better estimates for small sample sizes. It was also evident t…
Reliability of the Q-Sort Inventory of Parenting Behaviors
Test-retest reliability on the Q-Sort Inventory of Parenting Behaviors was obtained by using a sample of 30 mothers of 3-year-old children. The inventory consists of 72 statements, each of which describes a different parenting behavior and utilizes a forced-choice format. Mothers independently sorted the statements into nine ordered categories along a continuum from "most like me" to "least like me" and repeated the sort 2 weeks later. Analysis o…
Predicting Eating Disorders In Women
This study identified Millon Clinical Multiaxial Inventory (MCMI) items that differentiated eating-disordered women from university women. Item content revealed the eating-disordered women to be socially withdrawn and depressed
Children's Interests Inventory, Grades 4–6
A factored interest inventory for children was developed from interest items obtained from literature review and an open-ended questionnaire, the Preliminary Children's Interest Inventory, administered to children, parents, and teachers. These items, collapsed to form a 121 item Children's Interest Inventory, were rated on a 5-point like-dislike scale by 517 children in grades four, five, and six from Marshalltown, Iowa. Teachers rated each child…
Personal Reaction Scale for College and Noncollege Adults
The Personal Reaction Scale (PRS) was developed as a paper-and-pencil test for college and non-college adults to measure their locus of control perceptions. The 79-item PRS was administered to women college students (n = 150), their mothers (n = 105) and fathers (n = 88), and parents of 20 preschool-age children. Responses of 382 subjects were factor analysed to yield six factors: Fate, Social Self, Personal Self, Self-Determination, Luck, and Po…
Cooperative-Competitive Preferences and Behavioral Correlates as a Function of Sex and Age of School-Age Children
The objectives of the study were to: (1) develop a two-factor self-report preference measure of cooperation and competition; (2) explore the relationships between cooperative and competitive preferences, locus of control, social competence (parent rating), and school behaviors (teacher rating); (3) investigate sex and grade differences on the dependent measures. Factor analysis was employed on an 85-item inventory, administered to 120 children, r…
On an Indicator of Good Prediction
A high correlation between predicted and criterion values in cross-validation may not always be a sufficient indicator of goodness of prediction. An alternative indicator of goodness of prediction is reviewed in terms of what kind of prediction is sought
Interval Measurement
The meaning of interval measurement in physics stems from well supported theory which specifies the procedures for making measurements and provides the explicit functional relationship between variables derived from different measurement procedures. The concept of interval measurement may be heuristic but in applied fields of psychology and education it is not scientifically relevant because theory is inadequate to either specify how to obtain me…
On Squaring Validity Coefficients
The squared validity coefficient appropriately describes the proportion of variance in a criterion measure explained by a predictor when the predictor precisely measures its target construct and is linearly related to the criterion. Since neither of these conditions is closely realized in psychological measurement, the squared validity coefficient is an inappropriate descriptive statistic
Analysis of Repeated Measures and Other Designs
For small and balanced analysis of variance problems, standard computer programs are convenient and efficient. For large problems, regression pro- grams are at least competitive with analysis of variance programs; and, when a problem is unbalanced, they usually provide the only reasonable solution. This paper discusses procedures for using regression programs for the computing of analyses of variance. A procedure for coding matrices is described …
Transformations to Improve Reliability and/or Validity for Affective Scales
Issues in managerial performance
A Procedure for Estimation of Trait, Method, and Error Variance Attributable to a Measure
Alternative Methods of Analysis
A Fortran IV Program for Evaluating Internal Consistency and Single-Factoredness in Sets of Multilevel Attitude Items
The Use of Multiple Regression Procedures When the Predictor Variables are Psychological Tests
The Factorial Composition of Agct “Subtests” Along with College Aptitude Items and High School Grades
Item Difficulty as a Function of Perceived Item Directions
Interest and Ability Correlates of Graduation and Attrition in a College of Engineering
With the strain that increased enrollments are placing on the resources of many colleges and universities, these institutions are becoming more concerned with minimizing the inefficiency arising from student transfers. To both the student and the college, a transfer represents loss of time and money-whether the shift is between institutions or within a university. Perhaps nowhere is transfer a more disturbing problem than in colleges of engineeri…
