Empirical Research on Performance Improvement: An Update
In 2002, James Klein published a study based on a content analysis of research articles in PIQ from 1997 through 2000. That study was aimed at determining how much empirical research was being reported in HPT and what the focus of that research was. Klein found that only about one third of the articles published in PIQ represented empirical research. The current study replicates Klein's research for the years of 2001 through 2005. Results indicate that there has been a significant increase in empirical research published in PIQ in the last five years with empirical research now accounting for more than one half of all PIQ articles. Further clarification of the levels of evaluation for non-instructional interventions and the refinement of research questions in the field are suggested as ongoing needs. An analysis detailing the comparison of the two studies is provided.
