The new NIMH program announcement for Pilot Intervention and Services Research Grants (R34), available online at the following URL: http://grants.nih.gov/grants/guide/pa-files/PAR-09-173.html, provided a new framework for pilot studies such as R34's, with the focus on feasibility/acceptability, instead of the traditional framework that emphasized using pilot studies to obtain preliminary estimates for effect sizes to determine whether to conduct a large R01 trial in the future, and to use the preliminary effect sizes to conduct power analyses to determine the sample size for the R01 trial. This new framework largely followed the recommendations from various biostatisticians, such as Kraemer et al. (2006). We will discuss the implications of this new framework, and strategies for accommodating this framework in grant applications.
