The purpose of this research is to investigate the attitudinal, normative, and resource factors affecting psychologists’ adoption of an open data badge. The theory of planned behavior was employed to demonstrate how these factors influence behavioral intentions to adopt an open data badge. This research used a survey method to examine to what extent those attitudinal, normative, resource factors influence psychologists’ behavioral intentions to adopt an open data badge, and therefore engage in data sharing behaviors. A national survey (n = 341) across the field of psychology showed that perceived benefit and perceived risk had significant positive and negative relationships with attitude toward the open data badge respectively. Furthermore, attitude toward open data badge and norm of data sharing had significant positive influences on psychologists’ behavioral intentions to adopt the open data badge. Perceived effort had a significant negative relationship with the behavioral intention to adopt the open data badge, but had no effect toward attitudes surrounding the badge. However, this research found that the availability of a data repository and pressure from an open science journal did not have any significant relationship with behavioral intention to adopt the open data badge. The discussion includes implications for psychologists from both practical and theoretical perspectives. Additionally, future directions for gauging psychologists’ adoption of the open data badge and increasing data sharing behaviors are discussed.
