This is a response to Simms' commentary on Miller, Wolf, Harrington, Brown, Kaloupek, and Keane (2010) comparing the convergent and discriminant validity of two 4‐factor models of posttraumatic stress disorder (PTSD) using external measures of comorbidity. The author reviews the importance of the distinction between numbing and hyperarousal, clarifies the logic and rationale for the study's aims and hypotheses, and responds to specific concerns about the conclusions. He addresses the relationship between hyperarousal symptoms and internalizing comorbidity and notes the limitations of representing the latter construct using only two symptoms. The author concludes by underscoring the need for future research to place greater emphasis on examining the external correlates of alternative models of the factor structure of PTSD.
