Research highlighting the clinical importance of control and self-control is noted, and previous efforts to measure those constructs are reviewed. It is pointed out that control is a much more complex construct than was initially thought, and that more sophistication and precision is required in order to refine prior efforts to measure control and self-control. This article describes such an effort, a control content analysis scale, which is a coding instrument based methodologically on the content analysis research work by Gottschalk and Gleser. This instrument purports to be a "third generation" of control assessment inventory, and to build upon and extend previous efforts. The article provides a rationale, description, and coding explanation of the instrument's different categories; and suggests its potential theoretical, research, clinical, and training utility.
