Abstrakt: This shorter communication explores the concept of clinically significant change in treatment outcome studies for hoarding disorder. We argue that cross-study comparisons have been hindered due to researchers using different formulations to assess individual change. As a result, we propose that researchers adopt a standardized approach to calculating rates of clinically significant change for the Saving Inventory-Revised (SI-R) based on Jacobson and Truax's (1991) two-step method. Specifically, we recommend that individuals whose SI-R total scores have reduced by at least 20 points and whose post-treatment score is 38 or less be classified as recovered . Individuals whose total score decreases by 20 points or more, but whose post-treatment score remains above 38, should be classified as improved but not recovered . Individuals whose total score increases by 20 or more points should be classified as deteriorated . Any individual whose total score has changed by less than 20 points should be classified as not changed . By adopting these criteria, researchers will facilitate cross-study treatment outcome comparisons and aid in our understanding of the impact that hoarding treatment has on its recipients.
