Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To test these aims, adults will be recruited from Champaign-Urbana, IL, and surrounding communities to participate in a 12-week home-based and self-guided physical activity program. Eligible individuals will complete baseline questionnaires and informed consent online, and will wear an activity monitor for one week. Upon completion of questionnaires, participants will be randomly assigned to one of four conditions:
1. . The Base-App (BA) condition (i.e., Group D; so named due to the factorial design used in this study) will receive only a base-level smartphone app that contains three components common in computerized behavioral interventions: physical activity-related educational content (i.e., weekly videos, additional resources, easy weekly quiz questions), manual physical activity tracking, and instantaneous graphical feedback. As the physical activity program is goal-directed, these individuals will also receive printed goal setting worksheets.
2. . The BA+PT condition (i.e., Group C) will receive the Base-App plus an instantaneous points-based feedback module (PT) that provides "program points" for every task in the application (e.g., tracking physical activities, watching educational videos), and these are weighted by difficulty of the task. Points accumulate to earn "levels", and every fifth level brings a new motivational prompt and "badge" depicting an initially unfit character becoming increasing fit. Every tenth level will earn the participant a new "title" (e.g., "Intermediate Exerciser"). These points, levels, badges, and titles serve to provide instant positive feedback on progress within the program. These individuals will also receive printed goal setting worksheets.
3. . The BA+GS condition (i.e., Group B) will receive the Base-App plus a fully guided goal-setting module (GS). This module is based upon health behavior theory, emphasizing gradual exercise progression and highly specific, realistic, and measurable goals. The module will guide participants in setting both long and short term goals: each week, those with access to the GS module will be prompted to revisit and reset their goals. At this time, participants will select several aerobic and non-aerobic activities for the week, and will set a frequency (days per week) and duration (minutes per session) for each type of activity. To emphasize gradual progression, participants will receive a minimum, maximum, and recommended frequency and duration, and these will be calculated automatically within the app based upon performance in previous weeks.
4. . The BA+GS+PT condition (i.e., Group A) will receive all application components (i.e., Base-App, goal setting, instantaneous feedback). In addition to the features described above, program points accompany goal-related tasks (i.e., setting goals, revisiting goals, achieving goals).
Following completion of questionnaires, all participants will attend a group-specific orientation session. During this session, trained research staff will provide an introduction to the smartphone application used in the study and all relevant features, as well as a one-on-one physical activity counseling session in which staff members will work with participants to set initial aerobic and non-aerobic physical activity goals. During this time, participants will also be introduced to the goal-directed nature of the MAPS physical activity program. Short term (i.e., weekly) goals will specify the types of aerobic and non-aerobic activities that the individual will engage in, as well as the frequency and duration with which they will engage in these activities. Each participant's initial long-term goal will reflect federal physical activity recommendations. Accordingly, each participant will work toward achieving 150 minutes of moderate intensity aerobic activity, and at least two days of full-body muscle strengthening exercises within the 12-week intervention period. Staff will work with participants to modify these long-term goals based upon the participant's current abilities and physical activity level.
The program will begin on the Sunday following the orientation session. On each Sunday of the program, a new educational module related to basic health and health behavior concepts will be released, and participants will receive a brief email containing information related to the weekly educational content with a reminder to watch the new video. With the exception of the first week, these emails will also provide specific feedback (i.e., minutes of exercise, average intensity, and average enjoyment) from the previous week, and for those with access to guided goal setting the email will also provide feedback and advice based on whether or not the previous week's goals were met. Finally, each email will prompt the participant to revisit their short and long term goals, and adjust them as necessary. At this time, participants with the guided goal setting module will be brought immediately to that module upon entering the app, and will be asked to revisit and reset their short term goals. This process will include a recommended frequency and duration based upon previous performance in the program. Participants will also be prompted to set a new long term goal in the event that they achieved their previous long term goal during the week. For those without guided goal setting, this process will be carried out using traditional printed goal setting worksheets.
During each week, participants will utilize application features to track exercises as they do them, view their feedback, review their weekly goals, and view educational content. On each Thursday, participants will receive a text message update based upon their progress during the week. For those who have not accessed the app during the week, and for those who have not yet tracked activity during the week, a brief prompt will remind them to do so. For those who have tracked activity, a brief message will provide for them an update on the number of sessions and minutes of activity for the week.
During the final week of the program, participants will once again receive the activity monitor via mail and will be asked to wear it for one week. On completion of the 12-week program, participants will receive an email informing them that the program has completed. This email will also provide a link to follow-up questionnaires. At this time, research staff will also contact the participant to schedule a follow-up appointment, which will take no more than 60 minutes. During this appointment, participants will return the activity monitor and will complete a post-study survey assessing their experiences with the MAPS program and with the MAPS research staff.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A
Group A
This condition receives three study components:
1. The base-level of the smartphone app, which contains health-related educational content (i.e., weekly videos, additional resources, quiz questions), activity tracking, and graphical feedback.
2. The guided goal-setting module within the app that utilizes participant activity preferences and experiences, as well as performance within the program to guide the setting of high-quality short and long-term physical activity goals. These goals form the basis of the physical activity prescription.
3. The points-based feedback module. For each action in the app (e.g., setting goals, achieving goals, viewing weekly videos, answering quiz questions, tracking activity), a number of "program points" is awarded. These are weighted by task difficulty, and accumulate to earn "levels". Levels accumulate to earn "badges" depicting an avatar becoming increasingly healthy and active. Badges accumulate to earn "titles" (e.g., "expert exerciser").
