This research investigated whether LGBTQ* minority stress and public displays of affection (PDA; e.g., kissing, hugging) among LGBTQ* couples are context-sensitive. We expected that (a) LQBTQ* minority stress would be more prevalent in a harmful (i.e., city center) versus a less harmful (i.e., university campus) context, and (b) PDA would be reduced for LGBTQ* couples in a harmful context. In three studies, LGBTQ* and Hetero/Cis students (NTotal = 517) reported LGBTQ*-specific minority stress and PDA in the city and on campus. The city center was higher in minority stress than the campus in all studies. Also, LGBTQ* participants' PDA enjoyment was lower in the city than on campus (Studies 1 and 3). Minority stress mediated the context effect on PDA (Study 3). A qualitative analysis illuminated the harmful versus protective natures of public contexts. We conclude that a protective context can powerfully promote healthy LGBTQ* relationship behavior.
