  1. Values significant at P < 0.05 are marked in bold. Item 14 has no variance so a correlation coefficient cannot be calculated for it.
  2. MADRS = Montgomery-Åsberg Depression Rating Scale; PANSS = Positive and Negative Symptoms Scale; RLT = random letter test; SCCT = Standardized Copy of the Cube Test; YMRS = Young Mania Rating Scale.
