SECONDARY outcome

Timeframe: immediate post-test at completion of intervention

Population: 6 participants from HEART and 13 participants from Growing Minds did not complete the HIV/STD knowledge scale at post-test

HIV/STD knowledge was assessed with 9 items (e.g., "STDs usually have noticeable symptoms, like itching or burning"). These were adapted from previous sexual health knowledge questionnaires (Brown, DiClemente, \& Park, 1992; Morton, Nelson, Walsh, Zimmerman, \& Coe, 1996) and were used in our previous work (Widman, Golin, et al., 2018). Participants rated each item as True, False, or Don't Know. Responses were recoded as 0 (Incorrect or Don't Know) or 1 (Correct). Scores were summed to reflect the total number of correct HIV/STD knowledge questions (possible range=0-9).

SECONDARY outcome

Timeframe: immediate post-test at completion of intervention

Population: 6 participants from HEART and 13 participants from Growing Minds did not complete the condom beliefs scale at post-test

Participants' attitudes about condoms were assessed with the 3-item Effect on Sexual Experiences subscale of the Condom Attitudes Scale Adolescent Version (St. Lawrence et al., 1994). An example item includes, "Condoms take away the pleasure of sex." Responses were on a scale from 1 (Strongly Disagree) to 5 (Strongly Agree; alpha=.77). A mean of the three items was computed, such that higher scores indicate better outcomes (possible range 1-5).

Population: 6 participants from HEART and 13 participants from Growing Minds did not complete the sexual assertiveness scale at post-test

Self-reported sexual assertiveness was assessed with 3-items from the Multidimensional Sexual Self-Concept Scale (Snell, 1998). Items such as, "I'm very assertive about the sexual aspects of my life," were rated on a scale from 1 (Strongly Disagree) to 5 (Strongly Agree; alpha=.75). A mean of the three items was computed, such that higher scores indicate better outcomes (possible range 1-5).

Population: 6 participants from HEART and 13 participants from Growing Minds did not complete the safer sex intentions item at post-test

Intentions to discuss sexual health was assessed with a item developed by our research team based on items from the AIDS Risk Behavior Survey (Donenberg, Emerson, Bryant, Wilson, \& Weber-Shifrin, 2001) and our previous work (Widman, Golin, et al., 2018). This item asked how likely teens were to discuss sexual health issues, including pregnancy and STDs, with their partner(s) prior to sexual activity (communication intentions). Response options ranged from 1 (not at all likely) to 5 (very likely). Higher scores indicate better outcomes.

SECONDARY outcome

Timeframe: immediate post-test at completion of intervention

Population: 6 participants from HEART and 13 participants from Growing Minds did not complete the safer sex self-efficacy scale item at post-test

The Self-Efficacy for HIV Prevention Scale (Brown et al., 2014) was used to assess self-efficacy about communication and condom use. Six items assessed confidence communicating about sexual topics (e.g., "How sure are you that you could talk to your partner about safer sex?"). Two items assessed confidence obtaining and using condoms (e.g., "How sure are you that you could have condoms available when you need them?"). Participants responded from 1 (Couldn't do it) to 4 (Very Sure). A mean of all items was computed, such that higher scores indicate better outcomes (possible range 1-4; alpha=.79).
