Results from a study of 100 innercity adult Black diabetics indicate that perceived self-efficacy and age were strong predictors of adherence to an insulin regime. Additional psychosocial factors examined include perceived barriers to treatment, perceived severity of illness, and perceived social support. Results indicated gender differences. (IAH)

The internal correlation--a measure of dependency in a set of variables--is discussed and generalized. Applications of the internal correlation coefficient and its generalizations are given for several data-analytic situations. The internal correlation is illustrated and the concept is expanded to a series of additional indices. (TJH)

Use of internal correlation for statistical analysis--proposed by G. W. Joe and J. L. Mendoza (1989)--is discussed. Focus is on the "content" question (what this application can do with the information that statistics contain) and the "eloquence" question (the advantages of this means of encoding information over other means). (TJH)

Finds that, among 45 Mexican-American families, level of acculturation was significantly related to most external family systems variables: independence, achievement orientation, intellectual and cultural orientation, and active recreational orientation. Acculturation was not related to moral and religious emphasis or any measure of internal…

Multivariate distributions are studied in which all bivariate regressions can be linearized by separate transformation of each of the variables. A two-stage procedure, first scaling the variables optimally and then fitting a simultaneous equations model, is studied in detail. (SLD)

Reports on a study of the size of text windows, defined as a group of words appearing in contiguous position in text, and the effects of varying the window size on information retrieval performance. The characteristics of windows that best match terms in queries are examined in detail. (Contains 10 references.) (KRN)

Two new methods of estimating the mean population correlation (M) and the standard deviation of population correlations (SD) were suggested and tested by Monte Carlo simulations. Results show no consistent advantage to using the Pearson correlation or Fisher's Z in estimating M or SD; estimates from all methods are similar. (SLD)

Although the decennial census provides poverty figures for states and other subnational geographic units, their utility declines over the course of a decade, causing interest in producing postcensus estimates for a variety of indicators. This study extends recent efforts to estimate postcensus poverty figures for states using multiple regression…

In a study involving eight judges, analysis with the FACETS model provides evidence that judges grade differently, whether or not scores correlate well. This outcome suggests that adjustments for differences among judges should be made before student measures are estimated to produce reproducible decisions. (SLD)

It is shown that goodness-of-fit criteria developed for the evaluation of multivariate structural models can be applied to assist in evaluating the dimensionality of a test consisting of binary items, and correlative methods regularly used in factor analysis can be employed to diagnose causes of misfit.

Reports on the development and construct validation of two measures of high-risk sexual behavior for heterosexual adolescents. It was hypothesized that specific risky sexual behaviors would be interrelated, and that the cluster of high-risk sexual behaviors would be correlated with measures of other adolescent problem behaviors. Results provide…

Contrasts modeling methods in control theory to the methods of statistical generalizations in empirical studies of human or animal behavior. Presents a computer simulation that predicts behavior based on variables (effort and rewards) determined by the invariable (desired reward). Argues that control theory methods better reflect relationships to…

A hierarchical factor analysis of the intercorrelations among the Revised California Psychological Inventory (CPI-R) folk scales shows a strong general profile elevation factor for both men and women, which is noteworthy because it provides an empirical basis for interpreting the CPI-R as a measure of personal adjustment. (SLD)

Investigates the validity of the Reading Anxiety Scale. Finds that (1) reading anxiety shows a stronger negative correlation with reading achievement than does general anxiety; and (2) although general anxiety and reading anxiety correlate substantially, reading anxiety measures something beyond general anxiety. (RS)

A sample of 100 vocational students from 5 program areas completed a Student Self-Rating and 10 teachers completed a Teacher Rating, forms of the Generalizable Reasoning Skills instrument. Responses showed that students and teachers do not agree on students' level of reasoning skills. (SK)
