The three components tested will be: (a) LOCKOUT (no vs. yes); (b) TEXT (no vs. yes); and (c) EARN (no vs. yes). The investigators will use a highly efficient experimental strategy to detect effects of individual components as well as all two- and three-way interactions.\n\nThe secondary aim of this study is to examine how reductions in SST displace time into other active behaviors, i.e., light-intensity physical activity (LPA), moderate-to vigorous physical activity (MVPA) and activity type (e.g., housework, walking, exercise behaviors). The investigators will use both device-based (activPAL3c) and self-report (ACT24) measures to understand whether SST displacement can increase active behaviors, particularly MVPA.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '64 Years', 'minimumAge': '23 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 23-64.90 years of age\n* BMI≥25 kg/m2\n* 3+ h/day of SST\n* Insufficiently active\n* Own an Apple or Android smartphone/tablet\n* Access to internet at home or unlimited data plan\n* Willing to download StandUPTV\n* Able to read/understand English\n* Willing to be randomized\n\nExclusion Criteria:\n\n* Current smoker (more than once per week)\n* Major life event (e.g., move out of study area, pregnant)\n* MVPA contraindicated\n* Occupation requires media use or high amounts of physical activity\n* Drug abuse, major illness and/or psychological disorder'}, 'identificationModule': {'nctId': 'NCT04464993', 'acronym': 'StandUPTV', 'briefTitle': 'StandUPTV: Reducing Sedentary Screen Time in Adults', 'organization': {'class': 'OTHER', 'fullName': 'Arizona State University'}, 'officialTitle': 'StandUPTV: Reducing Sedentary Screen Time in Adults', 'orgStudyIdInfo': {'id': 'R01CA239612', 'link': 'https://reporter.nih.gov/quickSearch/R01CA239612', 'type': 'NIH'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'CORE', 'description': 'Participants will receive a "core" intervention which will include a basic version of the StandUPTV app and a Fitbit watch to use throughout the 16-week intervention.The Fitbit will provide device-based behavioral feedback through the StandUPTV self-monitoring component.
