description: This is a follow-up study of Study 1A of this registration. In study 1A, we had participants find out that their partner dated someone who was bisexual. In this study, we have changed the vignette to state that their partner reveals to them that they are bisexual. We are thus interested in understanding if the knowledge that your potential long-term partner is bisexual evokes a disease threat, and if there are there sex differences in attitudes and perceptions of disease when one finds out that their current partner dated a bisexual individual. Hypotheses Women will be more likely to encourage STI testing and condoms. Study design 1. Participants will be undergraduate men and women at Tulane University who are participants in a department-wide online study. 2. Participants will first be given informed consent. 3. They will then answer brief questions about their gender, orientation, and previous sexual history. 4. They will then be given a short vignette about their partner who they are deciding to form a long-term relationship with. In the vignette, they are told that they have been having sex with someone and are deciding to take their relationship to the next level. They then are told by their partner that their partner identifies as bisexual. 5. They will then be asked to report their level of upset, regret, disgust, if their partner got STI test if they want their partner to be tested, if they would get tested, and if they would use a condom. 6. They will then take the Perceived Vulnerability to Disease Questionnaire (Duncan, Schaller, &amp; Park, 2009), and the Sociosexuality Orientation Inventory (Penke &amp; Asendorpf, 2008). 7. They will then answer a demographic questionnaire and will be debriefed. Data collection procedures Data collection will be conducted via an online survey using Qualtrics. The participants at Tulane can access the survey from the online research platform known as SONA. Sample size 250-300 participants from Tulane. Based on G*Power, we will need 248 participants to detect a medium effect of f2 =.625, and to have the power of .8. Measured variables Dependent Variables Created by the research team from Study 1A. The 7 DV's that were created by the research team will generate seven mean composites. The three IVs that are exploratory will be used as a mean composite. Statistical models: A MANOVA will be conducted for the items asking about the vignette. A one-way MANOVA will use Sex (man or woman) as the grouping variable. Transformations: If data is not normally distributed, they will be winsorized. We will center the 3 scales that will be used in our exploratory analysis. Inference criteria: To infer statistical significance, we will use p&lt; .05. Data exclusion: If participants miss three or more of the DV’s, they will not be included in the study. If data points are 3 SD above or below, they will be winsorized. Furthermore, if the participants do not identify as a man or woman, they will not be used in our data analysis. Missing data: If participants miss two or less, the mean for the item will be inputted for that individual. Exploratory analysis: We will conduct a Moderation using Mean level Perceived Infectability, and Germ Aversion to measure how disgusted the participants will feel.
