The Sexual Experience Survey Short Form Victimization (SES-SFV) is the most widely used measure in sexual assault research. A primary strength of the measure is that it does not require participant to label their experiences as "sexual assault" or "rape." Rather, it utilizes a series of 10 sexually explicit questions that assess t past sexual behavior along a variety of dimensions. Experiences can be classified as "completed rape," "attempted rape," "coercion," "attempted coercion," or "nonconsensual sexual contact." Participants were assigned a score of "0" if they denied the question and a score of "1" if they endorsed the question. Participants with a score of 0 for all items were categorized as having no history of victimization. Participants with a score of 1 for any item assessing sexual coercion or nonconsensual sexual contact were categorized as having experienced sexual assault. Participants with a 1 for any rape item were catagorized as having experienced rape.

This subscale of the Gender Minority Stress and Resilience Measure will be used to assess the exploratory hypothesis that the ESD violence prevention training will produce reductions in rates of exposure to gender-related violence. At baseline, participants will indicate whether they have been exposed to a list of gender-related victimization experiences since the age of 18. At the 3- and 6- month post-intervention followup, participants will indicate whether they have been exposed to these experiences "since your last assessment." Sample items include "I have been threatened with physical harm because of my gender identity or expression." "I have been pushed, shoved, hit, or had somethin thrown at me because of my gender identity or expression." Higher scores indicate greater exposure to gender-related violence. A likelihood of victimization score was calculated based on the average response to all measures on this subscale ("yes" vs "no"). Range: 0-1

The Sexual Experience Survey Short Form Victimization (SES-SFV) is the most widely used measure in sexual assault research. A primary strength of the measure is that it does not require participant to label their experiences as "sexual assault" or "rape." Rather, it utilizes a series of 10 sexually explicit questions that assess t past sexual behavior along a variety of dimensions. Experiences can be classified as "completed rape," "attempted rape," "coercion," "attempted coercion," or "nonconsensual sexual contact." Participants were assigned a score of "0" if they denied the question and a score of "1" if they endorsed the question. Participants with a score of 0 for all items were categorized as having no history of victimization. Participants with a score of 1 for any item assessing sexual coercion or nonconsensual sexual contact were categorized as having experienced sexual assault. Participants with a 1 for any rape item were catagorized as having experienced rape.

To assess rates of exposure to sexual victimization we collapsed participants response into three dichotomous variable levels: 1) no history of victimization; 2) history of moderate victimization (non-penetrative assault); and 3) history of severe victimization (penetrative assault). Participants across each of the three groups received the same active treatment and were therefore assigned to a single treatment arm.

Rather, it utilizes a series of 10 sexually explicit questions that assess t past sexual behavior along a variety of dimensions. Experiences can be classified as "completed rape," "attempted rape," "coercion," "attempted coercion," or "nonconsensual sexual contact." Participants were assigned a score of "0" if they denied the question and a score of "1" if they endorsed the question. Participants with a score of 0 for all items were categorized as having no history of victimization. Participants with a score of 1 for any item assessing sexual coercion or nonconsensual sexual contact were categorized as having experienced sexual assault. Participants with a 1 for any rape item were catagorized as having experienced rape.

To assess rates of exposure to sexual victimization we collapsed participants response into three dichotomous variable levels: 1) no history of victimization; 2) history of moderate victimization (non-penetrative assault); and 3) history of severe victimization (penetrative assault). Participants across each of the three groups received the same active treatment and were therefore assigned to a single treatment arm.

This subscale of the Gender Minority Stress and Resilience Measure will be used to assess the exploratory hypothesis that the ESD violence prevention training will produce reductions in rates of exposure to gender-related violence. At baseline, participants will indicate whether they have been exposed to a list of gender-related victimization experiences since the age of 18. At the 3- and 6- month post-intervention followup, participants will indicate whether they have been exposed to these experiences "since your last assessment." Sample items include "I have been threatened with physical harm because of my gender identity or expression." "I have been pushed, shoved, hit, or had somethin thrown at me because of my gender identity or expression." Higher scores indicate greater exposure to gender-related violence. A likelihood of victimization score was calculated based on the average response to all measures on this subscale ("yes" vs "no"). Range: 0-1

A likelihood of victimization score was calculated based on the average response to all measures on this subscale ("yes" vs "no") among all participants who provided responses to at least two of the items on this scale. Participants across each of the three groups received the same active treatment and were therefore assigned to a single treatment arm.
