This study is to assess the feasibility of using a positive activities intervention, Positive Piggy Bank, in newly diagnosed women with breast cancer who will soon undergo surgery. A randomized controlled pilot trial of a brief self-guided positive activities intervention, The Positive Piggy Bank (PPB), compared to Treatment as Usual. 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," in the case of this study after approximately 21 days, 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 on the night before surgery.
