  1. Standard deviations are indicated in brackets. BD-I, BD-II, and BD-NOS refers to Bipolar Disorder type I, II and Not Otherwise Specified. Each patient completed one or several session(s) in the same mood state (according to our classification criteria). Unbalanced number of sessions were controlled for through mixed models (see Methods section).
  2. YMRS Young Mania Rating Scale, MADRS-S Montgomery Asberg Depression Rating Scale, self-rating version.
  3. aMood and group comparisons were tested using mixed models in R.
