Detailed Description
-----------------
In an effort to address the physical inactivity crisis among adolescents, the present study will examine the efficacy of using an already established Web-based social networking platform (i.e., Facebook) to deliver a physical activity intervention to adolescents. The primary objectives of this trial are to 1) test the efficacy of a social media-delivered physical activity program for increasing lifestyle physical activity in adolescents, and 2) determine the effectiveness of a physical activity intervention based on social cognitive principles in comparison to a simple information-based physical activity condition. Additional objectives include an examination of how program participation may influence psychosocial health and how these changes affect physical activity patterns in youth.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: SMART Behavioral Group<br>Intervention condition which has access to SMART Group Wall on Facebook and receives privately-delivered weekly behavioral modules. (SMART Facebook Group + video-based behavioral modules) | Behavioral: SMART Behavioral Group<br>* Test the efficacy of using social media to deliver a physical activity intervention based on social cognitive principles to increase lifestyle physical activity in low-active adolescents (i.e., access to regularly posted physical activity content on a study-specific, restricted access Facebook Group, as well as receipt of weekly video-based behavioral modules).<br>|
| Active Comparator: SMART Informational Group<br>Comparison condition (i.e., attentional control) has access to SMART Group Wall on Facebook, and receives privately-delivered weekly text-based messages with generic content. (SMART Facebook Group + NO video-based behavioral modules) | Behavioral: SMART Informational Group<br>* Test the efficacy of using social media to deliver a physical activity intervention to increase lifestyle physical activity in low-active adolescents (i.e., access to regularly posted physical activity content on a study-specific, restricted access Facebook Group, but does not receive the weekly video-based behavioral modules).<br>|
