Economic hardship |
Four items were used to assess economic hardship. One item assessed the number of hours per week to cover basic necessities (ranging from 1-5 hours/week to 16+ hours), and three items ask the extent respondents agree with specific statements. For example, "The time I spend earning money to cover my basic necessities (including tuition) frequently takes away from the time I have to study." The three statements are rated on a Likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). |

College shock |
Difficulty with transitioning to college or "college shock" was assessed via two items. Specifically, "My transition to college has been smooth" (1=strongly agree to 5=strongly disagree) and "Which statement best explains your previous educational experience? My previous educational experience..." (1=completely prepared me for my university's rigor; 4=has not at all prepared me for my university's rigor). Lower scores indicate less college shock. |

Medication use |
Participants were initially excluded from the trial if they were already taking medication, but it was not ethical to subsequently remove participants if they later required medication for mental illness (or other conditions) upon commencement of the study. We therefore asked, "Are you currently diagnosed with a condition that requires daily or weekly prescription medication (yes/no)?" For those who began taking medication, we also asked, "In the past month, how often did you take your medications as the doctor prescribed?" (1=Less than half the time, 5=All of the time). |

Alcohol use |
Consumption of alcohol was assessed with a single item with nine response options ranging from "None" to "4 or more drinks per day/week, otherwise 0-1 drinks/day." In addition, we assessed participants "Do you drink alcohol in moderation, according to the guidelines set forth by the American Heart Association (i.e. 1-2 drinks per day for men and 1 drink per day for women)? Yes or No. |

Perceived Stress |
The Perceived Stress Scale (PSS), developed by Cohen, Kamarck, and Mermelstein (1983) will be used to measure perceived psychosocial stress. The PSS is a 10-item scale that measures the extent to which situations are perceived as stressful. Responses range from 0 (Never) to 4 (Very often) and higher scores indicate a higher level of perceived stress. The Brief Job Stress Questionnaire, developed by Kawada and Otsuka (2011), is a 15-item scale measuring job stress. It focuses on the evaluation of job demands, job control, job support, and degree of job satisfaction. Responses range from 1 (Agree) to 4 (Disagree) and higher scores indicate a lower level of stress. |

Exercise self-efficacy |
Participants' beliefs in their ability to continue exercising in the future was assessed via McAuley's (1993) 6-item Exercise Self-Efficacy scale. Respondents rate their confidence to carryout exercise for the next six months, three times per week at a moderate intensity, for 40+ minutes per session. The scale is comprised of a 100-point percentage scale using 10-point increments, ranging from 0% (not at all confident) to 100% (highly confident). Total scores are calculated by averaging all six item responses where higher scores indicate higher self-efficacy. |

Exercise self-schema |
The Exercise Self-Schema Questionnaire (ESSQ; Kendzierski, 1988) will be used to assess participant "self-definition" or identity as an exerciser. The ESSQ was originally a 9-item scale and we are using a modified version which includes an additional item reflecting self-certainty ratings for each self-description item, as well as an extra question reflecting self-description, -importance, and -certainty with regard to "I am someone who will always be an exerciser" (Mullen, 2011). This 12-item version of ESSQ utilizes the same 11-point Likert Scale, ranging from 1 (does not describe me) to 11 (describes me). Items representing each subscale (self-description, importance, certainty) will be averages with higher scores indicating higher levels of each aspect of self-as-exerciser identity. Exerciser schematics will also be determined by categorizing responses to self-description and importance items that fall within the 8 to 11 range. |

Eating identity |
The Healthy Eating Self-Schema Questionnaire (Kendzierski & Costello, 2004) was used to assess participants' identity in relation to food. Specifically, self-descriptiveness of each of three key phrases, i.e., "healthy eater," "someone who eats in a nutritious manner," and "someone who is careful about what I eat," are self-rated on an 11-point scale ranging from 1 (does nor describe me) to 11 (describes me). Participants also rated importance of the phrases "to the image you have of yourself regardless of whether or not you are someone who is ..." Importance ratings are from 1 (not at all important) to 11 (very important). Participants are classified as healthy eater schematics if they rate at least two of the three descriptors as very self-descriptive (ratings of 8-11) and rated at least two of the three descriptors as very important to their self-image (ratings of 8-11). |

Exercise-related outcome expectations |
Participants' expectations about the outcomes of this intervention will be assessed using the Multidimensional Outcome Expectancies for Exercise Scale (MOEES). It is a 15-item questionnaire measuring physical outcome expectancies, social outcome expectancies, and self-evaluative outcome expectancies. Responses range from 1 (strongly disagree) to 5 (strongly agree). The total score for each subscale is calculated by summing the items, with higher scores being indicative of higher outcome expectations for exercise. |

Anticipated negative affect related to exercise |
Anticipated negative emotions will be assessed via the Anticipated Negative Affect Questionnaire (ANAQ; Wang, 2011). The ANAQ asks participants to anticipate how they may feel not regularly participating in physical activity. The ANAQ consists of 5 bi-polar items: "relaxed/tense," "not guilty/guilty," "no regret/regret," "not angry/angry," and "displeased/pleased." The ANAQ scale ranges from 1 to 7. Anticipated negative affect is scored based upon the number provided for each individual question, with higher scores indicating more negative emotions. |

Exercise motivation |
The Exercise Motivations Inventory-2 was used to assess the type of reasons one has for participating in an exercise program (and their relative strength). Only three of the 14 total sub-scales were implemented. Specifically, four items assessing appearance, three items assessing positive health, and four items assessing affiliation were used. Composite scores will be computed for each sub-scale by summing and averaging the numeric responses from the 6-point Likert-scale (ranging from 0=Not at all true for me, 5=Very true for me). Higher sub-scale scores reflect strong motivation for the respective reason for exercising. |

Sleep quality |
The Pittsburgh Sleep Quality Index (PSQI; Buysse et al 1989) is composed of 19 self-rated questions and 5 questions rated by a bed partner or roommate (only the self-rated items are used in scoring the scale). The self-administered scale contains 15 multiple-choice items that inquire about frequency of sleep disturbances and subjective sleep quality and 4 write-in items that inquire about typical bedtime, wake-up time, sleep latency, and sleep duration. The 5 bed partner questions are multiple-choice ratings of sleep disturbance. |

Frequency of forgetting |
The general rating of memory (first item) subscale was used from the Frequency of Forgetting scale (Zelinski & Gilewski, 2004). Specifically, respondents were asked, "How would you rate your memory in terms of the kind of problems that you have?" where 1=Major Problems and 7=Major Problems. Higher scores indicate more memory problems. |

Memory strategies |
The 20-item Strategies subscale of the Meta-memory Questionnaire (Troyer & Rich, 2002) was used to assess the extent to which participants' engaged in cognitive and behavioral strategies aimed at improving their memory over the past 2 weeks. Responses are rated on a 5-point Likert scale ranging from 0 (Never) to 4 (All the time). Items are summed and higher scores represent higher usage of memory aids and strategies. |

Exercise-specific memory self-efficacy |
Self-efficacy for remembering certain aspects of starting a new exercise program (e.g. public health recommendations, correct movements/form, optional modifications, and how to evaluate progress) was assessed with a novel questionnaire by Mullen and his colleagues. Responses ranged from 0% (Not at all confident) to 100% Completely confident). Composite scores are calculated by averaging the four-item sub-scales targeting self-efficacy for remembering the aforementioned aspects of aerobic, strength, and flexibility training. Higher scores indicate greater confidence in memory for each aspect of exercise training. |

Grit |
The original 12-item of the Grit scale (Duckworth et al, 2007) was used to assess the trait-level personality construct known as "grit." However, the shorter version (Grit-S; Duckworth & Quinn, 2009) will be derived from the larger scale, to be used in the calculation of total scores, given its superior psychometric properties. Higher scores will indicate higher levels grittiness. |

Personality dimensions |
The 44-item Big Five Inventory (John, Donahue, & Kentle, 1991) was used to assess the personality dimensions of Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to experience. Respondents are asked to consider the statement, "I see myself as someone who..." and then rate the extent to which they agree with a list of traits on a scale from 1 (Disagree Strongly) to 5 (Agree Strongly). Each subscale's items are summed and averaged. Higher scores reflect higher levels of personality dimension. |

Active choices |
The English-translated version of the Activity Choice Index (Mullen et al, 2016) was used to assess deliberate substitution of more effortful choices to engage in lifestyle physical activity. Specifically, self-reported lifestyle physical activities typical of the previous month were assessed with six items (using stairs or escalators, walking instead of using transportation, parking away from one's destination, using work breaks to be physically active, choosing to stand up instead of sitting, and choosing hand work instead of mechanic/automatic). Items are rated on a 5-point Likert scale (i.e., 1 = never, 5 = always). The composite score is calculated by averaging an un-weighted sum of each item. |

Cardiorespiratory fitness |
Cardiorespiratory fitness (CRF; Jurca et al. 2005) will be estimated according to an established algorithm involving gender, age, body mass index, resting heart rate, and a unique self-reported physical activity (SRPA) measure. The SRPA is a single exercise history question in which participants are asked to identify one of five physical activity categories that reflect their usual pattern of daily physical activity including activities associated with home and family care, transportation, work, exercise and wellness, and leisure or recreation. Given that the study design is entirely remote, resting heart rate will be assessed via open-ended response during survey administration using a 60-sec instructional video. |

Intentions |
Per the recommendations of Leon et al (2007) for reducing bias from dropout within randomized controlled trials, we assessed intent to dropout and related questions. Specifically, five items will be used to assess intentions to adhere to the TIPSTART program and comply with our study assessments (How likely is it that you will complete the next survey?), complete the study (How likely is it that you will complete the entire study?), and behavioral prescriptions associated with the intervention (If you are assigned to receive TIPSTART, how likely is it that you will adhere to our 10-week program? How likely is it that you will adhere to the exercise prescription [achieving 150-300 minutes of moderate intensity physical activity per week] for the duration of the study? How likely is it that you will complete our weekly online mental health sessions and remote check-ins?). Participants are asked to respond on a 0 to 9 Likert scale that ranges from "Not at all" (0) to "Extremely" (8). |

Self-reported leisure-time exercise |
Physical activity at baseline will be assessed via the Godin-Shephard Leisure-Time Physical Activity Questionnaire (GLTEQ; Godin, 2011). The GLTEQ assesses leisure-time activity across three modes of activity: strenuous, moderate, and mild, in terms of frequency and duration. Weekly frequencies of strenuous, moderate, and mild activities were multiplied by nine, five, and three, respectively to create the total score or number of units. According to this score, 24 units or more is indicative of an active individual, whereas any score below 24 is indicative of a non-active individual. |

Perceptions of Academic Stress |
The 18-item Perceptions of Academic Stress (PAS) scale by Bedewy and Gabriel (2015) was used to assess academic domain-specific stress. For example, participants are asked to indicate the extent to which they agree with statement such as, "Am confident that I will be a successful student," on a 5-point Likert scale (1=Strongly disagree, 5=Strongly agree). The PAS scale also addresses sources of stress, such as, "Teachers have unrealistic expectations of me" (1=Strongly agree, 5=Strongly disagree). Subscale scores will be computed by summing respective items and calculating an un-weighted averaged. Some scores will be reversed to ensure that lower composite scores reflect lower perceived stress. |

Self-efficacy to regulate school-life |
The Self-efficacy to Regulate Work and Life Questionnaire is a 5-item questionnaire that assesses how confident individuals are in regulating their work and non-work domains (Chan et al., 2016).The five items include: 1) "How confident are you in changing your lifestyle to achieve a good work-life balance?," 2) "How confident are you in finding out how to balance work and life?," 3) "How confident are you in achieving your ideal work-life balance?," 4) "How confident are you in implementing strategies to achieve work-life balance?," and 5) "How confident are you in inventing ways to balance your work and life?." Responses to all items are based on a scale ranging from 0 (cannot do at all) to 100 (highly certain can do). The composite score is calculated by summing and averaging the five items, with higher scores indicating that individuals are more confident in their abilities to cope with work-life challenges. |

Physical activity self-regulation |
The Physical Activity Self-Regulation Scale (PASR-12; Umstattd, Motl, Wilcox, Saunders, & Watford, 2009) will be used to assess the use of self-regulation strategies for engaging in physical activity. The PASR-12 is a 12-item questionnaire with responses ranging from 1 (never) to 5 (very often). A total score can be calculated by summing up responses to all the items. There are also six subscales (self-monitoring, goal-setting, social support, reinforcement, time management, and relapse prevention), however, research by our lab has found that this scale is not uni-dimensional. We will use a modified version of the scale. Higher score reflects higher use of self-regulation strategies. |

Exercise-related planning |
The Exercise Planning and Schedule Scale (EPSS; Rovniak, Anderson, Winett, & Stephens, 2002) is a 10-item questionnaire that assesses exercise scheduling and planning. Each question is based on a 5-point Likert scale, ranging from 1 (does not describe me) to 5 (describes me completely). The EPSS composite score is calculated by reverse-scoring items 2, 3, and 7 then summing and averaging the 10-items to create a composite score. Higher scores indicate more scheduling and planning done for exercise. In addition, we used a novel questionnaire asking participants the extent to which the following 5 statements are true (4-point Likert scale range: 1=Not at all true, 4 = Absolutely true). "For the next month, I have already planned... which days (frequency; F), the intensity (I), how long (time; T), which types (T), and where (location; L) I will exercise." F.I.T.T.L. scores will be averaged and higher scores represent greater planning. |

Self-efficacy to overcome barriers to exercise |
A 13-item questionnaire will be used to assess self-efficacy specific to possible barriers affecting exercise adherence. All items will be answered on a 0-100% Likert scale in increments of 10%. Prior research suggests that this may not be a uni-dimensional scale and therefore a composite will be based on a 4-item composite. These four items best reflect participants' confidence to self-regulate in the face of actual barriers, including exercising regularly in the face of bad weather, while on vacation, without encouragement, and when under personal stress. These four items will be averaged to generate our main outcome of interest, and the remaining nine items will be assessed for exploratory purposes. |
