PROJECT SUMMARY/ABSTRACT The purpose of this administrative supplement is to support Dr. Vanwoerden’s work on mentored career development K01 in the face of her upcoming critical life event, the birth of her first child. This supplement will support continuity of Dr. Vanwoerden’s research and overall productivity during a critical juncture in her career by providing funds to support a research specialist (RS). Together with funds from the parent award, this RS will be available on a full-time basis to help Dr. Vanwoerden with recruitment and scheduling of participants as well as in-person data collection during and following her planned time off. This extra support is critical to allow data collection to proceed on the timeline proposed in the parent K01 award, which involves hard-to-recruit sample of child-friend pairs with their respective mothers. Having a full-time RS after Dr. Vanwoerden returns on leave will be equally important to maintain progress in data collection while allowing Dr. Vanwoerden the time to process and analyze data, write papers, and complete training aims outlined in the parent K01 award as she manages with increased caregiving responsibilities. This supplement support is needed during a sensitive time in Dr. Vanwoerden’s career and will meaningfully influence her retention in the field of research and provide support to reach full research independence. There will be no changes to the aims, research design, and methods of the current project.
