The Social Risk and Resilience Factors (SuRRF) Lab at the University of Arizona aims to investigate how our social lives influence our health, for better and worse. The lab utilizes a range of methodologies including but not limited to use of electronic medical records, community cohort samples, ecological momentary assessment (EMA), ambulatory physiological data capture methods, and acute laboratory paradigms. Our lab work largely involves testing social phenomenon with an emphasis on measurement of acute cardiovascular responses including assessment of blood pressure and autonomic determinants of cardiovascular responses. Phenomenon of interest include the cardiovascular health effects (positive and negative) of stress, social vigilance, relationships, ethnicity, and discrimination. 



The lab is located on the 4th floor of the UA Psychology building. It includes a large primary space (672 sq ft) with dedicated resources for data processing, videoconferencing, and general storage. The facility also includes a dedicated experimental lab (218 sq ft). The experimental lab includes a participant chamber and adjacent control room and can be configured to study individuals or dyadic interactions with an emphasis on acute physiological responses

The SuRRF lab has equipment for conducting state-of-the-science non-invasive cardiovascular assessments. The lab is equipped to measure cardiovascular autonomic functioning, respiration, blood pressure and skin conductance. Core equipment includes 6 GE Carescape V100 Blood Pressure Monitors which are used throughout research and clinical settings and a dual impedance cardiograph system (Mindware Technologies). Impedance cardiography is a psychophysiological recording technology which allows for examination of heart rate and its autonomic determinants. Similar to ECG, it further breaks down the electrical signal inOoofdato its spectral components and conjoins it with measurement of blood flow to derive continuous measures HR, the autonomic branches, stroke volume, cardiac output, ejection fraction, ejection time, respiration, and interactions between these variables. In addition, the lab has significant resources for daily experience sampling including cell phones for collecting ecological momentary assessment data and ambulatory blood pressure monitors.

The lab also contains meeting space, significant videoconferencing equipment, conference phone systems, whiteboards, and other tools to facilitate team science.
