Ensuring Prevention Science Research is Synthesis-Ready for Immediate and Lasting Scientific Impact

When seeking to inform and improve prevention efforts and policy, it is important to be able to robustly synthesize all available evidence. But evidence sources are often large and heterogeneous, so understanding what works, for whom, and in what contexts can only be achieved through a systematic and comprehensive synthesis of evidence. Many barriers impede comprehensive evidence synthesis, which leads to uncertainty about the generalizability of intervention effectiveness, including inaccurate titles/abstracts/keywords terminology (hampering literature search efforts), ambiguous reporting of study methods (resulting in inaccurate assessments of study rigor), and poorly reported participant characteristics, outcomes, and key variables (obstructing the calculation of an overall effect or the examination of effect modifiers). To address these issues and improve the reach of primary studies through their inclusion in evidence syntheses, we provide a set of practical guidelines to help prevention scientists prepare synthesis-ready research. We use a recent mindfulness trial as an empirical example to ground the discussion and demonstrate ways to ensure the following: (1) primary studies are discoverable; (2) the types of data needed for synthesis are present; and (3) these data are readily synthesizable. We highlight several tools and practices that can aid authors in these efforts, such as using a data-driven approach for crafting titles, abstracts, and keywords or by creating a repository for each project to host all study-related data files. We also provide step-by-step guidance and software suggestions for standardizing data design and public archiving to facilitate synthesis-ready research.

It is crucial to robustly synthesize available evidence to inform and improve prevention efforts and policy, yet barriers such as inaccurate terminology and unclear reporting hinder comprehensive evidence synthesis. Practical guidelines and tools are provided to assist prevention scientists in preparing synthesis-ready research, with step-by-step guidance and software suggestions for standardizing data design and public archiving to facilitate synthesis-ready research. Using a recent mindfulness trial as an example, ways to ensure discoverability of primary studies and the presence of necessary data are demonstrated.
