This included the Bipolar Disorder Symptom Scale which was developed to briefly measure symptoms of both depression (cognitive and somatic) and hypo\/mania (affrontive symptoms and elation\/loss of insight). Participants could also submit voluntary or unsolicited app responses anytime; all were time\u2010 and GPS\u2010stamped.
