Child and adolescent therapy has progressed considerably as reflected in th
e sheer number of controlled studies, their methodological quality, and ide
ntification of empirically supported treatments. Even so, research is not l
ikely to make significant advances, in light of the way in which treatment
is studied and the emphasis on technique-focused questions. This article ra
ises 3 questions: What are the goals of child and adolescent psychotherapy
research? What type of research is needed to obtain these goals? How can we
determine whether we are making progress toward the goals? This article pr
ovides a plan to advance research that (1) emphasizes understanding the mec
hanisms or processes through which therapeutic change occurs, (2) draws on
developmental psychopathology research to inform treatment, (3) expands the
range of questions that guide treatment research, and (4) elaborates multi
ple treatment outcomes on which to base conclusions. Recommendations are ma
de to both develop the research agenda and to evaluate progress.
