Table 2 Test of similarity of narratives obtained within and across clinical diagnoses

Diagnostic Categories	Major Depressive Disorder (MDD, n = 30)	Bulimia Nervosa (BN, n = 30)	t-test
Major Depressive Disorder (n = 30)	0.120 (S.E. = 0.010)	0.030 (S.E. = 0.006)	t(1768) = − 7.670, p = < 0.010
Bulimia Nervosa (n = 30)	0.030 (S.E. = 0.006)	0.070 (S.E. = 0.009)	t(1768) = − 6.390, p = < 0.010

The table depicts the average Jaccard’s coefficient and standard error of 60 patients - either with a diagnosis of Major Depressive Disorder, or Bulimia Nervosa. The t-test were conducted between the average Jaccard’s coefficient of 870 possible pairs (30*29) within disorders and the average for 900 pairs (30*30) of the patients across-disorder
