This article explores the perceived value of public health research and the types of research considered useful in Ghana. Sixty-nine decision makers, researchers and stakeholders were interviewed. A broad range of research was highly valued. Two traits were important: an applied, relevant topic and quickly produced findings. Interviewees valued research which explored implementation issues or identified and increased understanding of health problems. Effectiveness research often lacked these traits and was not generally considered as important because it was implicitly assumed that as long as interventions (that were based on a good understanding of the situation) were implemented well, they would be effective.
