Measure	Intervention Students randomized to the intervention group will receive Me \& You Tech in place of their standard health education. Me \& You - Tech: The 13 MYT lessons will train youth to adopt a zero tolerance approach to dating violence (DV) and contain activities to enable youth to recognize healthy (non-abusive) and unhealthy (abusive) relationships, assess their own relationships, and adopt and practice a lifestyle paradigm of select-detect-protect informed by SCT self-regulatory frameworks. Within this lifestyle paradigm, youth select their personal rules to have only healthy (non-abusive) relationships, detect unhealthy (abusive) relationships that might threaten their rules, and learn to protect their rules using communication, management, and avoidance skills. MYT will tailor content by gender, relationship status, and the youth's DV profile of perpetration or victimization based on the Conflict in Adolescent Dating and Relationship Inventory (CADRI).	Control Students assigned to the standard care condition will receive their usual health education which usually includes knowledge-based content on violence prevention taught from the state textbook

The Acceptance of Dating Abuse Survey is a questionnaire to assess among adolescents' perceptions of their norm toward violence for boys and girls. A 6-item boys aggressing girls subscale is scored as 1 (Strongly Disagree) to 4 (Strongly Agree) for each item. Then a composite score is created. The higher the number the more accepting of boys aggressing girls under certain circumstances.

Me \& You - Tech: The 13 MYT lessons will train youth to adopt a zero tolerance approach to dating violence (DV) and contain activities to enable youth to recognize healthy (non-abusive) and unhealthy (abusive) relationships, assess their own relationships, and adopt and practice a lifestyle paradigm of select-detect-protect informed by SCT self-regulatory frameworks. Within this lifestyle paradigm, youth select their personal rules to have only healthy (non-abusive) relationships, detect unhealthy (abusive) relationships that might threaten their rules, and learn to protect their rules using communication, management, and avoidance skills.

Me \& You - Tech: The 13 MYT lessons will train youth to adopt a zero tolerance approach to dating violence (DV) and contain activities to enable youth to recognize healthy (non-abusive) and unhealthy (abusive) relationships, assess their own relationships, and adopt and practice a lifestyle paradigm of select-detect-protect informed by SCT self-regulatory frameworks. Within this lifestyle paradigm, youth select their personal rules to have only healthy (non-abusive) relationships, detect unhealthy (abusive) relationships that might threaten their rules, and learn to protect their rules using communication, management, and avoidance skills. MYT will tailor content by gender, relationship status, and the youth's DV profile of perpetration or victimization based on the Conflict in Adolescent Dating and Relationship Inventory (CADRI).	Control n=73 Participants Students assigned to the standard care condition will receive their usual health education which usually includes knowledge-based content on violence prevention taught from the state textbook
Perception of Peer Risk Behaviors as Assessed by the Perception of Peer Substance Use and Fighting Subscale	1.58 score on a scale Standard Deviation 0.73	1.71 score on a scale Standard Deviation 0.96

SECONDARY outcome

Timeframe: 6 months after baseline

Population: Data were not collected from 4 participants in the Intervention arm because they did not answer this question.

The Perception of Peer Risk Behaviors measure includes 7 items, including a 3-item 'Perception of Peer Substance Use and Fighting' subscale, that assesses youth perception of the total number of friends who engage in substance use and fighting. It is scored from 1 (None of them) to 5 (All of them) for each item with a total average score ranging from 1 to 5. Higher scores reflect greater perception of peer substance use and fighting.
