(0-10) - How anxious do you feel about your heart today? (0-10) - Have you taken any medication today? If yes, which one? - Have you taken your placebo spray today? (only in the placebo group) In addition, the respondents each complete two items to assess the effectiveness of the placebo (before and after the two weeks): - How much do you think the placebo will help you?
