Bridging the enormous gaps of theory with therapy research and practice

Convey remarkable advances in therapy outcome research and exemplify how leading investigators connect interventions to conceptual views about therapy. These comments focus on the distinction between broad conceptual views and theory about therapeutic change processes. Although there are explanations of why a treatment focus seems reasonable, there is very little testable theory or tests of theory in therapy research. The role, importance, and paucity of theory in child and adolescent psychotherapy research is described, underscored, and lamented, respectively, in these comments. Recommendations are made to move toward the goal of this series, namely, to bridge the gap of theory and clinical practice but also the gap of theory and therapy research.
