The Validity of the Successive Intervals Method of Psychometric Scaling

Psychometrika, 1956
The degree to which scale values computed by the method of successive intervals diverge from theoretically “true” values is seen to be due to three types of error: error due to inequalities in variances of the distributions from which the scale values are computed, error due to non-normality of the distributions, and sampling error. The contribution of

34E Future Challenges to Psychometrics: Validity, Validity, Validity

2006
Publisher Summary This chapter focuses on the most important factor contributing to the value of a testing program—that is, validity. Unfortunately, it is relatively easy to develop sophisticated models to help reduce the error of estimation by a few percent, so the vast majority of recent psychometric research has focused on more accurately modeling

Focus On psychometrics. Estimating construct validity

Research in Nursing & Health, 1991
AbstractThe meaning of construct validity and techniques for its estimation are discussed. Of particular interest is the appropriate role of factor analysis (and related techniques) in construct validation efforts. A comprehensive view of construct validity is encouraged, as well as a cautious interpretation of the construct validity evidence available
