This article presents comments on "Relapse Prevention Needs More Emphasis on Interpersonal Factors" by Stanton which is a comment on the original article "Relapse Prevention for Alcohol and Drug Problems: That Was Zen, This Is Tao" by Katie Witkiewitz and G. Alan Marlatt. In the current comment the authors of the original article respond to Stanton. Witkiewitz and Marlatt acknowledge that Stanton's comment is an important and thoughtful extension of the dynamic model of relapse they originally proposed. Stanton reviewed empirical research on the proximal role of social support in lapse events and provided a careful consideration of why interpersonal dynamics may serve as phasic processes within high-risk situations for relapse. Clearly the data provide support for an emphasis on interpersonal precipitants in the model. It is important to note that the relationship between interpersonal factors and treatment outcomes is not straightforward. The authors agree with Stanton that the dynamic relationship between interpersonal factors and relapse is an important area of future research. In general, the dynamic model of relapse that they proposed should be treated as an empirical question, and they encourage more critical thinking about, and revision of, the model. The field may benefit greatly by returning to the study of individual differences, systemic relapse processes, and the individual dynamics of treatment failure, as well as the protective factors that are predictive of treatment success.
