Abstract

This article provides a brief overview of the individual differences approach to research. This approach is first compared with the more familiar group-based approach to research. Following this comparison, some of the procedural and statistical issues central to individual differences research are noted. Ultimately, individual differences research has the potential to be of the greatest benefit to practicing clinicians; professionals who always deal with individual patients rather than the “average” or “typical” patient.
