The analysis of outcomes will follow the intention-to-treat (ITT) approach. Mean DCS, SWD, PrepDM and STAI scores will be compared using a t-test. Knowledge scores will be assessed by summing the number of correct responses to the questions, and compared using t-tests. Linear regression will be used in a secondary analysis to account for known predictors for decisional outcomes such as education. Secondary analyses will compare the mean DCS, knowledge, SWD, PrepDM and STAI scores before and after GC in the intervention arm to explore the additional benefit of GC after the DA. Un/adjusted mean differences and 95% confidence intervals will be reported. We will use descriptive statistics to report participants' characteristics.
