The structure of the job responsibilities scale: A multimethod analysis

The purpose of the present study was to investigate the psychometric charac teristics of the Job Responsibilities Scale (JRS). This article illustrates how factor analysis, cluster analysis, multidimensional scaling, and item response theory may be viewed as related data analyses, each capable of she dding insight into the structural dynamics of items designed to function as a measurement scale. Results of the analyses show that (a) the JRS measure s a continuum of increasingly greater job responsibility tasks, and (b) eac h method of statistical analysis provides unique, yet complementary, eviden ce in support of the JRS continuum.
