| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants Perpetrating Physical Dating Violence During Follow-up | One year | A 30-item measure assessing five types of dating violence perpetration and victimization was developed to meet specific needs of this research (Levesque, 2007). Alphas for the five 3-item perpetrator scales are: .88 for emotional mistreatment, .87 for controlling behavior, .91 for threats, .92 for physical violence, and .94 for sexual coercion. At follow-up, in the spring and fall of 2010, the measure assessed dating violence perpetrated and experienced since January 1, 2010. Given the hierarchical structure of the perpetration measure, the emotional mistreatment and controlling behavior scales were combined to represent emotional dating violence perpetration, and the threats, physical violence, and sexual coercion scales were combined to represent physical perpetration. Given extreme non-normal distributions, the two measures were then dichotomized. One or more incidents of physical perpetration during the period in question were coded as "yes," and no incidents as "no". |
| Secondary | Number of Participants Experiencing Physical Dating Violence During Follow-up | One year | See above. Cronbach's Alphas for the five victimization scales were .87 for emotional mistreatment, .86 for controlling behavior, .83 for threats, .76 for physical violence, and .90 for sexual coercion. One or more incidents of physical dating violence victimization during the period in question were coded as "yes," and no incidents coded as "no"). |
| Secondary | Number of Participants Perpetrating Emotional Dating Violence During Follow-up | One year | See above.One or more incidents of emotional dating violence perpetration during the period in question were coded as "yes," and no incidents coded as "no"). |
| Secondary | Number of Participants Experiencing Emotional Dating Violence During Follow-up | One year | See above.One or more incidents of emotional dating violence victimization during the period in question were coded as "yes," and no incidents coded as "no"). |
| Other | Number of Participants Perpetrating Physical Peer Violence During Follow-up | One year | Among participants not exposed to risk for dating violence, an 18-item measure assessed three types of peer violence perpetration and victimization (Levesque, 2007). Alphas for the three 3-item perpetrator scales are: .89 for emotional mistreatment, .89 for physical violence, and .94 for sexual coercion. At follow-up, in the spring and fall of 2010, the measure assessed peer violence experienced and perpetrated since January 1, 2010. Given the hierarchical structure of the perpetration measure, the physical violence and sexual coercion scales were combined to represent physical perpetration. One or more incidents of physical perpetration during the period in question were coded as "yes," and no incidents coded as "no". |
| Other | Number of Participants Experiencing Physical Peer Violence During Follow-up | One year | See above. Cronbach's Alphas for the three victimization scales were .89 for emotional mistreatment, .89 for physical violence, and .93 for sexual coercion. One or more incidents of physical peer violence victimization during the period in question were coded as "yes," and no incidents coded as "no"). |
| Other | Number of Participants Perpetrating Emotional Peer Violence During Follow-up | One year | See above. One or more incidents of peer emotional mistreatment perpetrated during the period in question were coded as "yes," and no incidents coded as "no"). |

|---|---|---|---|---|---|
| PRIMARY | Number of Participants Perpetrating Physical Dating Violence During Follow-up | One year | Participants who were exposed to at least minimal risk for dating violence -- i.e., who had experienced or perpetrated emotional or physical dating violence in the year prior to the study, who were current daters at baseline, or who dated during the follow-up period. | participants | NUMBER |
| SECONDARY | Number of Participants Experiencing Physical Dating Violence During Follow-up | One year | Participants who were exposed to at least minimal risk for dating violence -- i.e., who had experienced or perpetrated emotional or physical dating violence in the year prior to the study, who were current daters at baseline, or who dated during the follow-up period. | participants | NUMBER |
