A Pilot Study of a Brief Pre-Operative Intervention for Patients Undergoing Breast Surgery

"The PPB intervention involves noting at least one positive event each day, writing it down on a slip of paper and then depositing this piece of paper in a piggy bank. This practice is to take place at the end of the day, every day over a circumscribed period of time. At the end of the deposit period the participant closes the account and makes a full withdrawal by taking all of the slips out of the piggy bank and reading each one the night before surgery."
