Conducted exploratory field study to examine how age-concepts are experienced and to assess relationship of age identities to each other. Proposes Cognitive Age as a new multidimensional age scale that merges the standard scale, Identity Age, and Personal Age. Study results attest to Cognitive Age scale's reliability and validity.

The properties of nonmetric multidimensional scaling one explored by specifying statistical models, proving statistical consistency, and devloping hypothesis testing procedures. Statistical models with errors in the dependent and independent variables are described for quantitative and qualitative data. (Author/LMO)

After introducing some extensions of a recently proposed probabilistic vector model for representing paired comparisons choice data, an iterative procedure for obtaining maximum likelihood estimates of the model parameters is developed. The possibility of testing various hypotheses is discussed and the algorithm is applied to some existing data…

Examined the interpersonal structures of interviews by Ackerman, Bowen, Jackson, and Whitaker with the same family to identify common features across counselors. Multidimensional scaling provided a spatial representation of the hidden structure in the communication patterns of these interviews. Correlations indicated counselors' interactions were…

Concerned with consequences of employing the INDSCAL model when one of its assumptions are known to be violated. Under study is the notion that all individuals perceive the object space dimensions to be independent. (RC)

A maximum likelihood estimation procedure was developed to fit weighted and unweighted additive models of conjoint data obtained by categorical rating, paired comparisons or directional ranking methods. Practical uses of the procedure are presented to demonstrate various advantages of the procedure as a statistical method. (Author/JKS)

Investigated dimensions along which self-analytic group sessions vary. Identified three common dimensions: evaluation, potency, and activity. Used dimensions to describe phases of group development and individual differences in the perception of group sessions. (RC)

Some aspects of the small sample behavior of maximum likelihood estimates in multidimensional scaling are investigated with Monte Carlo techniques. In particular, the chi square test for dimensionality is examined and a correction for bias is proposed and evaluated. (Author/JKS)

An individual differences additive model is discussed which represents individual differences in additivity by differential weighting or additive factors. A procedure for estimating model parameters for various data measurement characteristics is developed. The method is found to be very useful in describing certain types of developmental change…

This paper presents a method which can be used to obtain evidence that the concepts rated on semantic differential scales are appropriate for given study. An analysis of six semantic differential concepts, as perceived by 168 graduate education students, is presented; variations of the method are discussed. (Author/GSK)

One of the most neglected aspects of group counseling and group psychotherapy research involves an investigation of the nature and development of the group members' interpersonal perceptions during the life of the group. In this study, an individual differences multidimensional scaling (INDSCAL) approach was used to study this question. (Author)

Examined the multidimensional nature of caregiver burden by specifically analyzing the patterns of association between five dimensions (in a sample of 160 caregivers) as measured by the Caregiver Burden Inventory and selected demographic, health, functioning, and well-being indicators. Time dependence burden was most influenced by patient…

Applied multidimensional scaling to similarity data to produce a model of Attachment Q-Set (AQS) items as points in a 3-dimensional space. Represented criterion sorts, individual Q-sorts, and empirical correlates as vectors, interpreting each according to the vector's contributions from the three global dimensions. Tested the model's validity and…

Monte Carlo techniques were used to examine regression approaches to external unfolding. The present analysis examined the technique to determine if various characteristics of the points are recovered (such as ideal points). Generally, monotonic analyses resulted in good recovery. (TJH)

Homogeneity analysis (multiple correspondence analysis), which is usually applied to "k" separate variables, was applied to sets of variables by using sums within sets. The resulting technique, OVERALS, uses optimal scaling. The corresponding OVERALS computer program minimizes a least squares loss function via an alternating least…
