Table 2 Mean Values and tests of differences of Polarity Indices in predominant polarity groups

From: Predominant polarity in bipolar disorder and validation of the polarity index in a German sample

  DPP MPP Kolmogorov-Smirnov Z p Mann-Whitney U-Test p
(N = 169) (N = 46)
  Mean (SD) Mean (SD)     
Total Polarity Index 1.95 (0.20) 2.17 (0.37) 5.947 .000*** 3579.5 .407
Polarity Index AP 1.87 (0.23) 2.20 (0.52) 6.091 .000*** 388.5 .997
Polarity Index MS 0.63 (0.50) 0.89 (0.96) 5.733 .000*** 3118.5 .024*
  1. *p< .05.
  2. ***p< .001.
  3. DPP = depressive predominant polarity, MPP = manic predominant polarity, UPP = uncertain predominant polarity, AP = Antipsychotics, MS = Mood Stabilizers.
