Note that this list is non-exhaustive. Core Understanding America Study survey measures, repeated quarterly for sociodemographics and at least biennially for other variables, are available from 2014. For ALiR, survey measures are repeated monthly and minute-level data from wrist-worn Fitbits are collected continuously. ALiR activities occur for at least 1 year, though participants may subsequently choose to contribute indefinitely. Contextual data from public datasets are matched geospatially and temporally to participant timelines. Specific instruments are in parentheses. HRS = University of Michigan’s Health and Retirement Study; PROMIS = Patient Reported Outcomes Measurement Information System; PhenX = National Institutes of Health’s Consensus Measures for Phenotypes and eXposures. ACEs = Adverse Childhood Events Scale; PSS-4 = Perceived Stress Scale-4; USDA = U.S. Department of Agriculture; (i)ADL = (instrumental) Activities of Daily Living; ASSIST = World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test; BRFSS = Behavioral Risk Factor Surveillance System; GAD-7 = General Anxiety Disorder-7; PHQ-8 = Patient Health Questionnaire-8.
