Couple Confirmation. In order to participate in this study, both partners in the couple must complete the screener, meet all eligibility criteria, and be confirmed by study staff to be an actual couple. Couple confirmation will involve separate calls to each partner with a series of questions to elicit information about the individual, his partner, and their relationship (i.e., information only an actual couple would know about one another). After these phone calls, study staff will review the responses to determine agreement. Once staff has confirmed that the two participants are a couple, they will be contacted to schedule an in-person meeting where they will complete a consent form and the baseline assessment.
