The baseline trait and state anxiety scores were equally distributed in both groups: 53.42 (5.26) in nurse counselling versus 53.20, (4.83) in CBE. This was also the case in state anxiety prior to colonoscopy. Comparing both groups, we noted an expected rise in anxiety scores between the moment of education and just before colonoscopy. The small difference in the rise of scores, indicating a possible benefit of either modality, was not significant amongst groups: 3.09 (6.98) versus 2.83 (7.90), p=0.437. (Table 3.)
