Sexual assault is prevalent and may be even more prevalent among sexual minorities. However, prevalence rates vary, in part, due to discrepancies in sampling methods. Given this, we assessed whether two popular non-probability sampling types (panel quota vs. social media recruitment) produced different sexual assault prevalence rates when holding all other methodological choices (definitions, measures, scoring) constant in a sample of lesbian, bisexual, queer, and heterosexual adults, excluding cisgender men. Two phases of data collection occurred—a panel quota sample (n = 1366), recruited from an online sample aggregator, and social media sample (n = 1102), recruited through lesbian, gay, bisexual, transgender, and queer (LGBTQ) social media sites. Participants were asked about sexual assault and rape experiences in both childhood and adulthood using a modified form of the Sexual Experiences Scale-Short Form Victimization. Both phases used the same definitions of sexual assault, prevalence measures, and prevalence scoring. Overall, the sample recruited via LGBTQ social media yielded statistically higher sexual assault prevalence rates for all four types of victimization experiences measured: lifetime sexual assault (LSA), rape-specific LSA, childhood sexual assault (CSA), and adulthood sexual assault. However, when parsing out subgroups, this finding only held for heterosexual participants who had rates > 30% higher in the social media sample compared with the panel quota sample. These findings suggest that researchers studying sexual assault in lesbian, bisexual, or queer adults may be able to use social media sampling techniques, which require less resources, without concern that the sampling technique is inflating prevalence when compared to panels.

性侵犯很普遍，在性少数群体中可能更为普遍。然而，流行率有所不同，部分原因是抽样方法的差异。鉴于此，我们评估了两种流行的非概率抽样类型（小组配额与社交媒体招募）是否在女同性恋、双性恋、酷儿和异性恋成年人，不包括顺性男性。发生了两个数据收集阶段——面板配额样本 ( n = 1366)，从在线样本聚合器中招募，以及社交媒体样本 ( n= 1102)，通过女同性恋、男同性恋、双性恋、变性人和酷儿 (LGBTQ) 社交媒体网站招募。参与者被问及童年和成年时期的性侵犯和强奸经历，使用修改后的性经历量表 - 短期受害形式。这两个阶段都使用相同的性侵犯定义、患病率测量和患病率评分。总体而言，通过 LGBTQ 社交媒体招募的样本在所有四种类型的受害经历中都产生了统计上更高的性侵犯流行率：终生性侵犯 (LSA)、强奸特定的 LSA、儿童期性侵犯 (CSA) 和成年期性侵犯。然而，在分析子组时，这一发现仅适用于社交媒体样本中的比率比面板配额样本高出 > 30% 的异性恋参与者。
