The investigators are developing a smartphone intervention that aims to make proven psychosocial interventions for bipolar disorder more readily and routinely accessible to patients as part of their day-to-day lives. The intervention, called LiveWell, will capture and feedback data about sleep and activity to assist patients in regularizing daily rhythms as well as help them monitor, recognize, and manage early warning signs of impending mood episodes. Behavioral and self-report data collected by the phone will also be used to provide clinicians with information regarding patient clinical status. This will increase patient-provider communication and allow for better evaluation and targeting of treatment.
