Objectives

Social and psychological interventions are often complex. Understanding randomised controlled trials (RCTs) of these complex interventions requires a detailed description of the interventions tested and the methods used to evaluate them; however, RCT reports often omit, or inadequately report, this information. Incomplete and inaccurate reporting hinders the optimal use of research, wastes resources, and fails to meet ethical obligations to research participants and consumers.

Methods

In this paper, we explain how reporting guidelines have improved the quality of reports in medicine, and describe the on-going development of a new reporting guideline for RCTs: CONSORT-SPI (an extension for social and psychological interventions).
