Recollection (control condition) The recollection condition was selected because it has been used in a prior study by our team of a phone-based positive psychology intervention and it was found to be feasible and well-accepted. Each week, subjects will record recent life events in a manual without describing emotions associated with the events. The nature, setting, or type of events to be recorded will differ each week to provide variety and maintain subjects' interest. This will be described as an intervention that may assist with organization and hone recall of important life events. Also, as an attentional control, it has a parallel structure to the experimental arm with a treatment manual, weekly exercises, and weekly calls to review exercises.
