NORC Clinical and Community Human Assessment and Interventions Core

The Core collects data in the form of 24-hour recalls for both internal and external clients. A 24-hour recall is an in-depth interview that collects detailed information on all foods and beverages consumed by a participant during the previous 24 hours. NDSR is a Windows-based dietary analysis program designed to collect and analyze 24-hour dietary recalls, food records, menus, and recipes. The Automated Self-Administered 24-hour (ASA24) Dietary Assessment Tool is a web-based tool that enables multiple, automatically coded, self-administered 24-hour recalls and/or single or multi-day food records, also known as food diaries.

Processing of samples to include: centrifuging of blood, urine and other samples as needed for testing, shipping or storing.

Rates may be affected depending on the level of processing required.

rate is based on: Effort, RN (SC) (0.03334 h) + Effort, Study coordinator (TS) (0.05 h) + Effort, Technologist (SI) (0.1 h) + Sample processing supplies (0.8 units)

Accelerometry is the preferred method of measuring physical activity among free-living physical activity individuals. The Core provides assistance with quality assurance checks on the data, prepares data, and processes output files.

In-person or online meeting with Core Director, Physical Activity Expert, and Manager to including discussion of methods, sample size, detailed project special considerations, and budget development.  Physical Activity consultations commonly cover overall project needs, research goals, and literature based best practices, including suggestions for novel approaches.

The Core collects physical data in the form of recalls for both internal and external clients as a supplement to the 24-Hour Diet Recall (NDSR & ASA24) service. The Core collects data in the form of 24-hour recalls. A recall is an in-depth interview that collects detailed information on all physical activity performed by a participant over a specific time frame. The time associated with each recall includes staff time for set-up, documentation, actual interview time, quality assurance (data checks for completion and accuracy), analysis of data output files, and time spent to generate datasets for investigators/clients along with documentation. The long form of this service includes more than 8 physical activity questions.

Training for investigators that wish to have research staff training to direct study participants on the use of physical activity instruments in including: interviewer administration, use of accelerometry or activity trackers,  advice on techniques to increase adherence, and opportunities for project support once data collection begins.

The Core will provide assistance with all parts of projects as needed, on a daily basis. This will include but is not limited to: training study coordinators to use tracking databases, updating tracking databases according to study coordinator comments, monitoring data load of project, securely storing all data files, as well as communicating any participant issues encountered back to study site.

The Core has the ability to create customized databases and food frequency questionnaires for diet assessment, available for use by researchers per request. This process includes the development of specialized questionnaires, the creation of food composition database to accompany questionnaire, as well as the time necessary to write statistical programming that must accompany data to create meaningful results.

Consultation for laboratory processing, subject recruitment, scheduling, telephone screening, informed consent, study design, IRB submission, and anthropometric measurements.
