REGRESSION
For the main analysis, we estimated joint tests of significance and For the measure of whether a participant agreed to be tested for HIV, and whether she actually took the test (binary variables):To model the number of condoms left in the bowl, we used a tobit specification with a lower censor of 0 and an upper censor of 20, the maximum number of condoms contained in the bowl. We also used a tobit model to analyze responses to the questions about risk perception since these data are censored between 0 and 100.For the risk-perception questions and the number of condoms taken from the bowl:We also conducted an exploratory sub-group analysis, using a logit regression model and a tobit regression model, to estimate whether any effects of the self-affirmation manipulation on the condom use and HIV test measures depended on the specific proud moment that participants discussed, or on how long they spent discussing their proud moments.We analyzed the data using STATA Intercooled version 15.1 statistical software (StataCorp, 2015). The experiment and the data analysis plan were pre-registered at
