Absolute and relative frequencies of reliable change.

Low ruminators (n = 44) High ruminators (n = 45) Test statistic
Appointment 1: Inline graphic(2) = 8.432, p < .05
Reliable decrease 0 (0.00%) 3 (6.67%)
No reliable change 37 (84.09%) 26 (57.78%)
Reliable increase 7 (15.91%) 16 (35.55%)

Percentages refer to the relative frequencies in the corresponding subsample (low or high ruminators) and the test-statistic indicated Inline graphic-tests comparing the distribution of RCI-categories in low and high ruminators at the respective appointment.
