There are a number of similarities between the moderated common factors proposal of Sprenkle and Blow (this issue) and the multilevel, process-based therapeutic change presentation of Sexton, Ridley, and Kleiner (this issue). Despite these areas of agreement there are fundamental differences in our respective positions. We suspect that these differences are not unique to the respective authors, but instead represent the current debate in the field regarding common factors. In this commentary, we discuss what we think are important issues to have emerged from these articles. Our hope is that the issues we present below will take the debate and discussion one step further.
