AsPredicted.org Pre-Analysis PlansRegistry

AsPredicted.org is “a standardized pre-registration that requires only what’s necessary to separate exploratory from confirmatory analyses.” You can easily generate a short  and simple pre-registration document that “takes less effort to evaluate than it takes to evaluate the published study itself.” The form, designed by Uri Simonsohn, Joe Simmons, and Leif Nelson, has only nine questions, which are general enough that they are relevant to nearly all disciplines and types of research.

AEA RCT EconomicsRegistry

The American Economic Association (AEA) Randomized Controlled Trials Registry is a registry for RCTs conducted in the social sciences. Because existing registries were not well suited to the need for social sciences, in April 2012, the AEA executive committee decided to establish such a registry for economics and other social sciences.

OSF Data RepositoryRegistrySoftwareVersion Control

Open Science Framework (OSF) is part version control system, part data repository, part collaboration software that allows researchers to move study materials to the cloud, share and find materials, detail individual contributions, make research design more visible, and register materials to certify research design was not modified to alter outcomes. To increase workflow flexibility OSF offers a system where researchers can register a description of their study and its goals. The OSF emphasizes versatility with a very wide range of tools and features including add-ons from other related sites such as Dataverse and Github. Uploaded materials can also be archived and receive a Digital Object Identifier (DOI) or Archival Resource Key (ARK).

EGAP Political ScienceRegistry

The Evidence in Governance and Politics (EGAP) Registry focuses on designs for experiments and observational studies in governance and politics. The registry allows users to submit an array of information via an online form. Registered studies can be viewed in the form of a pdf on the EGAP site. The EGAP registry is straightforward and emphasizes simplicity for registering impact evaluations.

ClinicalTrials.gov Public HealthRegistry

ClinicalTrials.gov is a registry and database that provides information on publicly and privately funded clinical trials, maintained by the National Library of Medicine at the National Institutes of Health. Studies are often submitted to the site when they begin and are regularly updated along the way. ClinicalTrials.gov is the largest trial registry, with over 250,000 studies from across the world.
