Abstract
This article provides an introduction to the special issue on intervention development and cultural adaptation research with diverse families. The need for research on intervention development and on cultural adaptation of interventions is presented, followed by a discussion of frameworks on treatment development. Seven articles included in this special issue serve as examples of the stages of treatment and intervention development, and of the procedures employed in the cultural adaptation with diverse families. An overview of the seven articles is provided to illustrate the treatment development process and the use of pluralistic research methods. We conclude with a call to the field for creative and innovative intervention development research with diverse families to contribute to the body of evidence-based practice with these populations.
