Quantitative studies geared toward understanding differences among prison inmates in their odds of committing rule infractions have grown over the last decade but with little consistency in the models examined, especially regarding the types of rule violations examined. These differences have, in turn, contributed to an increasingly complex picture of inmate misconduct that appears counterproductive for both theory and practice. The study described here was designed to assess the ramifications of examining different outcome measures for quantitative analyses of the subject. Findings revealed that three of the nine models examined produced unique information regarding the effects of various inmate predictors, including the models of physical assaults (on inmates and/or staff), drug/alcohol use, and other nonviolent misconduct. Analyses also uncovered several new substantive findings on the topic. Findings are discussed in light of their relevance for practice as well as theories of inmate behavior.
