Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The research team will develop a mobile application, referred to as the app, to collect data on a subject's daily phone usage and activity engagement. The app will comprise three features, with specific sets of features being activated during different phases.
* Feature 1: The app will autonomously track the time spent on the apps categorized as social media and gaming.
* Feature 2: The app will display the daily amount of usage on social media and gaming apps, with an option for a subject to confirm their acknowledgment of the daily time spent.
* Feature 3: The app will display an option for subject to confirm their engagement in the alternative activities as planned.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Research questions:
1. What are the effects of self-reflection, alternative activity engagement, and contingency management in reducing the severity of problematic smartphone use?
2. What is the feasibility and acceptability of the various intervention strategies?
Research hypothesis:
1. Participants who receive the self-reflection intervention will have a greater reduction in their PSU compared to participants who receive no intervention.
2. Participants who receive the intervention combining self-reflection and alternative activity engagement will have a greater reduction in their PSU compared to participants who receive no intervention and participants who receive only self-reflection intervention.
3. Participants who receive the intervention combining self-reflection and contingency management will have a greater reduction in their PSU compared to participants who receive no intervention and participants who receive only self-reflection intervention.
College students who are 18+ years old, use an Android smartphone, identified as having problematic smartphone use (scored 31+ on the Smartphone Addiction Scale), and interested in learning strategies to reduce unwanted smartphone use are eligible for participation.
Intake session: Research subjects who are eligible for participation will meet with a designated graduate student research assistant for consent and app installation. Subjects who provide consent and meet the eligibility criteria will be asked to install the app that will be used to track a subject's daily smartphone usage and their engagement in assigned interventions. The intake meeting will be about 10-30 minutes. Following the consent and eligibility screen, subjects will also be randomly assigned to one of the four conditions, including three intervention conditions and one control condition. The randomization will be conducted by the PI.
2-week baseline phase: Following the intake session, subjects' daily smartphone usage will be tracked for two weeks to establish baseline data. During this phase, only Feature 1 of the app will be activated.
4-week intervention phase: After the 2-week baseline phase, subjects who are assigned to intervention conditions will meet with the designated graduate student research assistant to learn about the intervention strategy, identify goals of daily PSU reduction, and update the app for an assigned condition. This meeting will be about 30 minutes to 1 hour.
* Subjects who are assigned to Condition 1(Self-reflection) will be guided to actively review their smartphone usage data each day. In this condition, Features 1 and 2 of the app will be activated.
* Subjects who are assigned to Condition 2 (Self-reflection + Alternative activity engagement) will be guided to develop a plan for alternative activity engagement. Each day, subjects will actively review their smartphone usage and engage in alternative activities as planned. In this condition, Features 1, 2, and 3 of the app will be activated.
* Subjects who are assigned to Condition 3 (Self-reflection + Contingency management) will be guided to actively review their smartphone usage data each day. If the subject meets their daily PSU reduction goal, they will receive an incentive ($8) that day; if they do not meet their goal, they will receive nothing. In this condition, Features 1 and 2 of the app will be activated.
* Subjects who are assigned to Condition 4 (Control condition) do not engage in any active intervention. Their daily smartphone usage will be tracked using the app. In this condition, only Feature 1 of the app will be activated.
At the end of the 4-week intervention phase, subjects will be asked to complete an online survey that assesses their severity of PSU. Subjects who receive interventions will also be asked about their involvement, acceptability, and satisfaction with the assigned intervention.
2-week follow-up phase: After the 4-week intervention phase, subjects will be asked to stop the assigned intervention. Subjects' daily smartphone usage will be tracked for additional 2-weeks to establish follow-up data. In this condition, only Feature 1 of the app will be activated.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Self-reflection
Participants actively review their smartphone usage data each day, which will be verified by the app.
Self-reflection
Participants will be guided to identify goals of daily PSU reduction. o Participants will be guided to actively review their smartphone usage data each day.
Self-reflection + Alternative activity engagement
Participants actively review their smartphone usage and engage in alternative activities which are identified by the participants, which will be recorded and verified via the app.
Self-reflection + Alternative activity engagement
Participants will be guided to identify goals of daily PSU reduction and actively review their smartphone usage data each day. Participants will be guided to develop a plan for alternative activity engagement and confirm their engagement in the alternative activities as planned.
Self-reflection + Contingency management
Participants will actively review their smartphone usage each day, which will be verified via the app. If the participant meets their daily PSU reduction goal, they will receive an incentive ($8); if they do not meet their goal, they will receive nothing.
Self-reflection + Contingency management
Participants will be guided to identify goals of daily PSU reduction and actively review their smartphone usage data each day. Participants will receive an incentive ($8) if they meet the daily PSU reduction goal.
