Emerging research indicates that people use multiple strategies to manage their emotions in everyday life. Yet, we know little about what these strategy combinations look like, how they function, or how individual differences influence these phenomena. We addressed these issues in two, 2-week daily diary studies performed during the height of the COVID-19 pandemic ( = 422; data collected April and September 2020).

In the present studies, we attempt to better identify the expected effect dimensions perceivers seem to utilize to make action characterizations related to the Big Five and HEXACO personality dimensions.

Selected military personnel are immunized with an FDA-licensed anthrax vaccine unless there are clinical contraindications. The objective of this analysis is to capture the experience of soldiers receiving anthrax vaccine to assist in better patient-provider communication and clarify the safety profile of the vaccine in this population as a quality-assurance initiative. Between August 1998 and July 1999, 2824 soldiers immunized against anthrax at one military clinic completed a structured medical note that was reviewed by a clinician.
