“…Indeed, we found that 68% of SGM youth who were not out would refuse to participate in a biomedical HIV prevention study that required guardian permission for these reasons (Fisher, Arbeit, Dumont, Macapagal, & Mustanski, 2016). In both cases, investigators attempting to increase SGM youth’s representation in sexual health survey research may face challenges recruiting unbiased samples of youth if guardian permission is not waived, thereby limiting the generalizability of findings to SGM youth whose parents are accepting of their sexuality and gender identity (Fisher & Mustanski, 2014; Mustanski, 2011; Tufford, Newman, Brennan, Craig, & Woodford, 2012). In addition, investigators may be more inclined to exclude SGM adolescents from sexual health research due to anticipated or actual difficulties obtaining IRB approval or waivers of guardian permission (Miller, Forte, Wilson, & Greene, 2006; Mustanski, 2011).…”
