An international study was undertaken to determine the differences in attitude and approach to outdoor leadership preparation for experts from five nations. Characteristics derived from a canonical discriminant function analysis were used to explain the differences in North America and provide the foundation for a model program. (Author/CW)

Multidimensional scaling (MDS) and its potential use for research and evaluation in health-related professions are discussed. Useful data types, interpretation of results, and various applications of MDS are presented. MDS is less restrictive than factor analysis since it does not assume a linear relationship between the objects/variables of…

Describes a study that examined quantifiable characteristics of library schools to construct a model that predicts a judgment of perceived quality of library schools. Two perception studies conducted by Herbert White are discussed, statistical methods used are explained, and recommendations for further research are given. (34 references) (LRW)

Presents logistic discriminant analysis as a means of detecting differential item functioning (DIF) in items that are polytomously scored. Provides examples of DIF detection using a 27-item mathematics test with 1,977 examinees. The proposed method is simpler and more practical than polytomous extensions of the logistic regression DIF procedure.…

Two discriminant function analyses were conducted to determine the cognitive/educational profile which differentiated 4 groups of 68 elementary/secondary level students: attention deficit disorder (ADD), with and without medication; learning disabilities (LD); and nonhandicapped. By treating the LD and nonmedicated ADD subjects as one group, a…

Describes simple conceptual framework for academic intervention that extends functional-analysis procedures to basic academic skills. Organizes research into five hypotheses that can guide interventions. Presents treatment for six academic interventions and procedures for testing effectiveness. Discussion of procedures includes design issues,…

This retrospective study examined long-term effects of Drug Abuse Resistance Education (DARE) by assessing substance use among undergraduates. Results from a multiple discriminant analysis found that after accounting for effects of age, there were no substantial group differences in substance use. These findings add to a growing literature that…

The Gambling Timeline Followback (G-TLFB), a measure of gambling behavior that uses the timeline followback methodology, was psychometrically evaluated with samples of frequent-gambling young adults. Seven dimensions of gambling behavior were assessed: type, frequency, duration, intent, risk, win-loss, and consumption of alcohol while gambling.…

Any effort to understand academic departments would be facilitated by a better understanding of its relationship between its two larger spheres: the institution and the discipline. This study particularly asks: How do the relationships between institutional culture and the culture of the academic department vary by disciplinary field? Using…

The purpose of this research was to examine and extend portions of the sociocultural model of bulimia nervosa (Stice, E. (1994). Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action. "Clinical Psychology Review," 14, 633-661; Stice, E., & Agras, W. S. (1998). Predicting onset and…

We describe a principled way of imposing a metric representing dissimilarities on any discrete set of stimuli (symbols, handwritings, consumer products, X-ray films, etc.), given the probabilities with which they are discriminated from each other by a perceiving system, such as an organism, person, group of experts, neuronal structure, technical…

In survey research, nonresponse has been one of the major concerns about survey accuracy and validity. A case in point is the increasing use of surveys in mass communications research; much previous research has dealt with nonresponse among the general public, but little is known about nonresponse in special subgroups in the population where any…

Data from three subtests (language, mathematics, and social) scales of the Head Start Measures Battery (HSMB) were analyzed using principal components analysis (PCA) and non-metric multidimensional scaling (MDS). The HSMB measures preschool development in language, mathematics, nature and science, perception, reading, and social development. The…

A study examined Nigerian journalists' self-reported perceptions of editorial ethics and of the role of editorials in national development, comparing data with an earlier content analysis of the ethics of newspaper editorials. Subjects, 348 full-time, salaried Nigerian journalists on nine national newspapers in two newspaper ownership groups,…

Self-perception is considered a central issue in several psychological fields, especially in research on learning and personality.
