Screening Visit: The purpose of this visit is to determine eligibility and obtain informed consent. Inclusion and exclusion criteria will be assessed through medical record review, a screening interview, and a hormonal bloodspot kit. A questionnaire will also be given to determine level of depressive symptoms and to assess for suicidality. The hormonal bloodspot kit involves a finger prick and obtaining about 5-6 drops of blood. If lab analysis of this kit determines abnormal hormonal levels, persons will be excluded from further participation in the study. Participants will be given a saliva kit to gather 4 saliva samples at home over the course of one day. Participants will store these saliva samples in their refrigerator. They will either bring in the kit at the time of their study visit or mail the kit in a prepaid box given to them (the hormones in the saliva are shelf stable for up to 3 weeks; we will ask participants to refrigerate the samples if they are not immediately mailing them or bringing them to the study site. In this way we will best ensure that samples will be preserved and usable). All participants enrolled in the study will be under the impression that they will be participating in a catastrophizing experiment during their study day. However, only half of the participants will actually experience the 10-minute stress experiment on experiment day. We have included this minor form of deceit in the protocol so we can control for the anticipatory stress of expecting to experience a negative emotional experiment. We highlight here that the mild deception will occur for only half the sample (those going into the control group) and it represents a decrease in risk for these persons.
