Registered Reports are a new model for scientific publications designed to increase replicability and transparency. In this model, studies undergo peer review prior to data collection and if of sufficient quality, receive in-principle acceptance and publication regardless of the direction of results. As a new model, it has been infrequently used for personality research. Adaptation by individual differences researchers will likely present novel barriers requiring adaptive solutions. Speakers in this symposium will present their experiences with ongoing Registered Reports on many topics across personality research--health, measurement, clinical, and genetics. In addition to their proposed questions and methods, speakers will discuss any challenges they have encountered and solutions they have generated in adapting this mechanism for personality research. Speakers & talks included: Jeewon Oh: Changes in optimism in response to life events: Evidence from three large panel studies. Dr. Susan South: Testing a multidimensional factor structure of the self-control scale. Cassandra Brandes: Maladaptive extremes of the Five Factor Model in children. Dr. Jaime Derringer: Anticipating effect sizes & shapes in gene-by-environment interactions.
