I believe that the biggest problem facing I/O Psychology is poor measurement. When you ask persons to indicate how well a personality question represents them, for example, even people with the same levels of the personality trait can differ widely in their response. These problems are exacerbated by asking persons to make judgments of others or more subtle aspects of the organizational environment.
My interests center around measurement issues. These include different ways to statistically model different measurement instruments (e.g., structural equation modeling, and item response theory) as well as more basic scale development issues.
I also believe that the role of the internet in the workplace will grow in the future. Recently, I have become interested in issues related to the internet. For example, are internet administered questionnaires really equivalent to those collected via paper and pencil? Also, what role does the internet play when people are looking for jobs?
