Remarks on tucker's inter-battery method of factor analysis

Tucker's inter-battery method of factor analysis is shown to assume implicitly that, within the factor space of overlap between the vector configurations of the two test batteries involved, the locations of the two sets of principal axes and the sizes of the associated characteristic roots are identical. A suggested modification of the inter-battery method to avoid these restrictions is considered.The opinions expressed are those of the author and are not to be construed as reflecting official Department of Army policy.     

A solution for case iii of the law of comparative judgment

A solution for Case III of the Law of Comparative Judgment, modeled after Thurstone's solution for Case IV but eliminating the restrictive assumption of relatively equal discriminal dispersions, is developed.     

Relationships between locus of control,health value,and preventive health behaviors among women

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended.
