Items are rated on a 5-point scale from 0 'not at all' to 4 'completely.' Scores range from 0-28 with higher scores indicating higher exercise self-efficacy.

Description: Walk Score® is publicly available and measures the walkability of any address using a patented system. For each address, Walk Score ® analyzes hundreds of walking routes to nearby amenities and awards points based on distance to each amenity. Walk Score® also measures pedestrian friendliness by analyzing population density and road metrics such a block length and intersection density. Scores are given on a scale of 0 to 100.

Description: MedGem® is an FDA cleared and validated indirect calorimetry device. It is handheld and measures oxygen consumption (V02) to determine resting metabolic rate (RMR).

Description: The BRFSS is a state-based system of health surveys that collects information on health risk behaviors, preventative health practices, and health care access primarily related to chronic disease and injury. The GLB-TBI uses the two subscales of Healthy Eating and Physical Activity from the 2017 version of the BRFSS. It consists of 14 items.

Description: Quality of life will be assess using the stroke impact scale (SIS), which assesses 8 dimensions of health-related QOL specific to people post CVA including subscales (using a 5pt Likert scale) assessing strength, memory and thinking, emotion, communication, activities of daily living, mobility, hand function, and participation/role function

Description: This inventory consists of 40 life events and asks the participant to recall if any of the events happened within the previous year (e.g., death of spouse; personal illness; change in sleep). Endorsement of these events are totaled and higher scores indicate a greater amount of stressful life events. Point values for the Holmes and Rahe Stress Inventory were weighted and summed for each individual based on scoring instructions. Individuals who scored 150 points or less were categorized as low susceptibility to a health breakdown in the next two years, 151-300 points were 50% chance of health breakdown, and 301 points or more were 80% chance of health breakdown.

Description: The MOCA is a brief, 8-section assessment of various cognitive domains including executive function, memory, language, attention, concentration, orientation, and working memory in neurologic populations.Each item on the MOCA is allocated a set of points adding up to 30.

Description: The self-reported habit index (SRHI) measures the self-reported perceptions of habit strength for an identified behavior. It consists of 12 items for each selected behavior and uses a 7-point Likert scale from "completely disagree" to "completely agree." Higher totals represent greater perception of habit strength. The SRHI showed high reliability across four studies with alphas of .89, .92, .89, .94, .95, .94, and .85.

Description: The Modified Rankin Scale (MRS) measures the degree of disability or dependence for daily activities of people who have had a stroke. The MRS is an ordinal scale with six categories ranging from zero (no symptoms) to five (complete physical dependence). A score of six signifies death.

Description: The Pain Interference-Short Form is taken from the Patient-Reported Outcomes Measurement Information System (PROMIS). This measure is used to assess adult self-reported consequences of pain and pain consequences (e.g. interference in social, cognitive, emotional, physical and recreational activities). This measure consists of four questions with five response option ranging from one to five. The sum of all responses creates a total raw score. This measure is normed to the US general population.

Description: The Sleep Disturbance-Short Form 4a is taken from the Patient-Reported Outcomes Measurement Information System (PROMIS) and used to assess adult sleep disturbance profiles. This measure has four questions, each with five response options ranging in value from one to five. The sum of each response creates a total raw score. The measure is normed to the US general population.

Description: Waist circumference will be measured at the umbilicus following ACSM guidelines. A total of three measurements will be taken and an average of the three will be the final measurement used. Measurements will be scored in centimeters.

Description: Fasting venous sample will be obtained for hemoglobin a1c to assess average blood sugar level over the past 2-3 months. Coordinators are trained phlebotomists.

Description: Fasting venous sample will be obtained. Coordinators are trained phlebotomists.

Description: Fasting venous sample will be obtained. Coordinators are trained phlebotomists.

Description: Isrin, Angiogenic factors (VEGF), Total Homocysteine, Lipoprotein-associated phospholipase A2 (Lp-PLA2), ICF-1, Brain derived neurotrophic factor (BDNF), and Tau proteins (total and phosphorylated) will be drawn to assess relationships with outcome variables.

Description: A modified version of Prochaska and DiClemente's Stages of Change model will be administered to measure readiness for behavior change. The measure consists of two behaviors (eating and exercise) with five questions each related to a stage of change (precontemplation, contemplation, preparation, action, maintenance).

Description: The metabolic score calculator will be used at all time points to determine the risk for metabolic syndrome. The following variables will be used to determine metabolic risk using the free metabolic risk calculator: gender, race and ethnicity, systolic blood pressure, fasting glucose, triglycerides, high-density lipoprotein (HDL), weight, height, and waist circumference. Scores are calculated are standardized to the general population.

Description: This self-report survey was developed by the National Institute of Mental Health. The full survey consists of 64 questions with an open-ended section at the end to elicit concerns and feedback related to the effects of COVID-19. For this current study, however, only sections on Exposure Status (10 items), Life Changes (15 items), and Emotions/Worries (7 items), and the open-ended question will be asked. Questions are asked "over the past two weeks."

Description: The Social Isolation Short-Form 4a is taken from the Patient-Reported Outcomes Measurement Information System (PROMIS). This form assesses the perceptions of being "avoided, excluded, detached, disconnected from, or unknown by, others. There is no timeframe for the form. The measure is normed to the US population.

Description: To assess media exposure and fear of media exposure during COVID-19 we have added 6 questions. These are asked "over the past two weeks." These questions address time spent watching the television, listening to radio, reading the newspaper, and searching the internet and social media. In addition, a 6th question related to fear is asked using a 5-point Likert scale.
