Manipulation Check

“As a manipulation check, we will first conduct an independent samples t-test to determine whether perceptions of the age at which transgender youth can identify their gender relative to cisgender youth differs by condition using the age difference score outlined above as the dependent variable.”

Serial Mediation Model

“Next, we will test a serial mediation model in which both the perceived gender development age gap and autonomy support mediate the relationship between condition and support for anti-transgender legislation, such that condition will influence the perceived gender development age gap, which will influence autonomy support, and then finally support for anti-trans legislation.”

Secondary Analyses

Additional Moderation Models

“We will measure a secondary dependent variable which will be used for additional analyses (see below). We will measure participants’ trust in scientists on a single-item scale in which participants will be asked to indicate on a scale from 1 (strongly distrust) to 7 (strongly trust) how much they trust or distrust scientists as a source of information about gender development (adapted from Hmielowski et al., 2014).”

“In addition to our planned serial mediation model, we will also test two moderation models. As described above, we expect participants who receive the intervention (relative to those who do not) will show a reduced age gap in their perception of gender identity development. We further predict that this effect will be greater for participants who express more trust in scientists, as has been the case in previous work examining motivated reasoning about scientific findings (Drummond & Fischhoff, 2017).”.

“Additionally, because transgender rights are a highly politicized topic (Hatch et al., 2022), we expect the predicted effect will be greater among more highly educated liberal participants, in line with research from other similarly politicized domains (e.g., global warming; Drummond & Fischhoff, 2017). Thus, we will test moderation by these variables through two linear regression models (one model with condition and trust in scientists and another with condition, political ideology, and education).”

Moderated mediation model

“Secondary analyses will also include a moderated mediation model to determine if this model is a better fit than our planned serial mediation model. Specifically, we will also test a moderated mediation model where the relation between the perceived gender development age gap and autonomy support varies by condition.”
