2. Considering the above pilot study results: What is the overall feasibility of the SMART research protocol in its current form? Are there any changes required for the main trial? This includes: recruitment approach, intervention content and delivery (app, provision of human support), and/or trial assessments (online and in-person). conditions: Health Behavior conditions: Noncommunicable Diseases conditions: Mental Health Issue conditions: Lifestyle Risk Reduction studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: SEQUENTIAL primaryPurpose: PREVENTION masking: DOUBLE whoMasked: INVESTIGATOR whoMasked: OUTCOMES_ASSESSOR count: 200 type: ESTIMATED name: LvL UP name: LvL UP + MI name: Comparison measure: Mental well-being measure: Subjective well-being measure: Mental health (depression) measure: Mental health (stress) measure: Health-related quality of life measure: Health behaviours (physical activity) measure: Health behaviours (steps) measure: Health behaviours (diet 1) measure: Health behaviours (diet 2) measure: Health behaviours (sleep) measure: Health behaviours (smoking and alcohol consumption) measure: Anthropometry (body weight) measure: Anthropometry (body height) measure: Anthropometry (waist circumference) measure: Anthropometry (hip circumference) measure: Anthropometry (self-reported height and weight) measure: Resting blood pressure measure: Blood metabolic profile measure: LvL UP app: Response time measure: LvL UP app: Duration of app usage measure: LvL UP app: Actual usage of app components measure: LvL UP app: Coaching topic / sub-topic use measure: LvL UP app: Conversational turns measure: LvL UP app: Breeze (slow-paced breathing tool) usage measure: LvL UP app: Access to smartphone sensors (location - obfuscated) measure: LvL UP app: Access to smartphone sensors (location types) measure: LvL UP app: Access to smartphone sensors (raw gyroscope) measure: LvL UP app: Access to smartphone sensors (raw accelerometer) measure: LvL UP app: Access to smartphone sensors (physical activity) measure: LvL UP app: Access to smartphone sensors (WiFi connection status) measure: LvL UP app: Access to smartphone sensors (WiFi networks in range) measure: LvL UP app: Access to smartphone sensors (bluetooth scan) measure: LvL UP app: Access to smartphone sensors (battery % level and charging status) measure: LvL UP app: Access to smartphone sensors (screen on/off) measure: LvL UP app: Access to smartphone sensors (call and SMS metadata) measure: LvL UP app: Access to smartphone sensors (app usage & app name from notifications and action) measure: LvL UP app: Access to smartphone sensors (step count) measure: LvL UP app: Access to smartphone sensors (brightness) measure: LvL UP app: Access to smartphone sensors (breeze audio) measure: LvL UP app: Access to Apple Healthkit & Google Fit data measure: Process evaluation: Health literacy questionnaire measure: Process evaluation: Stages of change questionnaire measure: Process evaluation: Unintended consequences measure: Process evaluation (intervention group participants only): Net promoter score measure: Process evaluation (intervention group participants only): System usability scale measure: Process evaluation (intervention group participants only): Session alliance inventory measure: Process evaluation (intervention group participants only): Self-report habit index measure: Process evaluation (intervention group participants only): MITI-4 measure: Process evaluation (intervention group participants only): UMars measure: Process evaluation (intervention group participants only): Interview measure: Process evaluation (Research team): Field Notes measure: Exploratory aims: Sociodemographic measure: Exploratory aims: Use of digital health technologies measure: Exploratory aims: Ecologic Momentary Assessment of mood state measure: Exploratory aims: Personality measure: Exploratory aims: Work Engagement measure: Exploratory aims: Self-reported sickness absence sex: ALL minimumAge: 21 Years maximumAge: 59 Years stdAges: ADULT facility: Saw Swee Hock School of Public Health status: RECRUITING city: Singapore zip: 117549 country: Singapore name: Shenglin Zheng, MSc role: CONTACT email: shenglin.zheng@u.nus.edu lat: 1.28967 lon: 103.85007 facility: Singapore ETH Center status: ACTIVE_NOT_RECRUITING city: Singapore zip: 138602 country: Singapore lat: 1.28967 lon: 103.85007 hasResults: False
