Describes several salient features of multidimensional scaling (MDS) for spatial distance models including proximity measures, interpoint distances, goodness-of-fit, and distinctions between metric and nonmetric scaling. Four commonly used MDS computer programs are described, and a section on applications of MDS selected from the counseling…

Describes the use of multidimensional scaling (MDS), emphasizing applications in counseling and vocational psychology. Includes an example of one standard nonmetric scaling method. Addresses conceptual and practical considerations associated with the use of MDS. (Author/KS)

Describes the loglinear model, and applies it to categorical data cross-tabulated on four dimensions. Defines contrasts similar to those of the analysis of variance and describes post hoc and planned comparison strategies. Illustrates hypothesis testing and model building for categorical data, providing guidelines for performing an analysis on…

Discusses design, development, and evaluation of scales used in counseling psychology research. Describes methods of scale construction including the Thurstone, Q-sort, rank-order methods, Likert, semantic differential, Guttman, Rasch, and external criterion methods. Presents ways of evaluating newly developed scales. Discusses measurement versus…

Argues that co-citation methods combine citing behavior of authors by assuming they share common view of scientific literature which affects assessments of dimensionality and clustering of articles. Co-citation matrices, effects of shared point-of-view assumption, and co-citation compared with bibliographic coupling and centroid scaling are…
