Note. CI = confidence interval; HPV = human papillomavirus; LGBT = lesbian, gay, bisexual, and transgender; OR = odds ratio. The multivariate models included only the variables displayed in the table.
Low knowledge was defined as ≤ 3 (of 6) correct knowledge items and high knowledge was defined as ≥ 4 correct knowledge items.
4-point response scale ranging from “not at all” to “a lot” (coded 1–4).
3-item scale; each item had a 4-point response scale ranging from “not at all” to “a lot” (coded 1–4).
4-item scale; each item had a 5-point response scale ranging from “strongly disagree” to “strongly agree” (coded 1–5).
2-item scale; each item had a 5-point response scale ranging from “strongly disagree” to “strongly agree” (coded 1–5).
5-point response scale ranging from “strongly disagree” to “strongly agree” (coded 1–5).
