By study design, almost all participants (At 12-month follow-up, 79% of lesbian and 83% of bisexual girls (Overall, results suggested significant moderating effects of age, sexual identity, and sexual experience on rates of condom use and use of other contraception. Although there were no significant moderating effects on abstinence, pregnancy, or intentions (A summary table of subgroup effect sizes is provided in Table Subgroup analyses of treatment effects on pregnancy preventive outcomes6 m: 1.46 (.60–3.59)9 m: .47 (.21–1.09)12 m: 1.01 (.49–2.08)6 m: .59 (.18–1.90)9 m: .32 (.13–.76)12 m: .62 (.31–1.23)6 m: 9.26 (0–13.92)9 m: .88 (.53–1.47)12 m: .65 (.39–1.07)6 m: 2.68 (.24–29.90)9 m: 1.33 (.08–21.45)12 m: 2.01 (.33–12.25)6 m: 1.39 (.86–2.23)9 m: 2.11 (1.18–4.88)12 m: 1.69 (1.01–2.38)6 m: .67 (.31–1.44)9 m: 1.01 (.63–1.65)12 m: .90 (.56–1.46)6 m: 1.88 (.17–13.92)9 m: .90 (.64–1.27)12 m: .88 (.62–1.25)6 m: 1.52 (.49–4.69)9 m: .40 (.10–1.55)12 m: .56 (.13–2.36)6 m: 1.37 (.51–3.71)9 m: 1.39 (1.06–2.70)12 m: 2.65 (1.31–5.34)6 m: 1.10 (1.01–1.77)9 m: 1.11 (1.07–1.89)12 m: 1.13 (1.07–1.78)6 m: 9.02 (0–33.19)9 m: 1.05 (.68–1.62)12 m: .96 (.62–1.48)6 m: 1.40 (.23–8.50)9 m: .15 (.02–1.26)12 m: .36 (.07–1.91)6 m: 1.61 (1.11–2.33)9 m: .84 (.42–1.67)12 m: 1.05 (.62–1.80)6 m: .69 (.26–1.35)9 m: .91 (.57–1.47)12 m: .89 (.56–1.40)6 m: 2.31 (.21–25.70)9 m: .80 (.54–1.18)12 m: .71 (.48–1.05)6 m: 2.05 (.59–7.09)9 m: 1.74 (.28–10.49)12 m: 2.33 (.42–12.83)6 m: 1.44 (.65–3.22)9 m: 1.47 (1.07–2.89)12 m: 2.09 (1.12–3.89)6 m: .40 (.17–1.93)9 m: 1.05 (.47–2.29)12 m: .98 (.48–2.00)6 m: 13.02 (0–28.02)9 m: .80 (.47–1.35)12 m: .84 (.50–1.40)6 m: 1.71 (.54–5.37)9 m: .58 (.17–2.04)12 m: 1.04 (.26–4.26)6 m: 2.89 (.42–5.89)9 m: .69 (.36–1.31)12 m: 1.15 (.63–2.07)6 m: 1.33 (.47–3.82)9 m: .67 (.42–1.09)12 m: .72 (.45–1.15)6 m: 2.113 (.19–23.63)9 m: .89 (.61–1.30)12 m: .73 (.50–1.40)6 m: 2.13 (.19–23.64)9 m: .99 (0.00–31.59)12 m: .71 (.12–4.25)Statistical significance would be indicated by a confidence interval that does not include 1.00OR/IRR (95% CI) reported for each model. Models are adjusted for baseline levels of the outcome of interest, and sexual experience where applicableSimilarly, sexual experience, which was a binary indicator of ever having penile-vaginal sex, was a moderator of the intervention effects on rates of condom-protected sexual acts (Finally, sexual identity was a significant moderator of intervention effects in both condom use and contraception use over time, with effects sizes in the small to medium size (No significant effects of the intervention on abstinence or pregnancy were detected (
