Correlation between neuroticism and the total score of the IBS severity index in the study population. A significant correlation was observed between the score for neuroticism and the IBS-SI score in all the subjects (r = 0.15, p = 0.0001). The corresponding correlation was r = 0.12 (p = 0.0001) in the C-IBS group and r = 0.09 (p = 0.0440) in the A-IBS group, both representing weak correlations. There was no significant correlation between the scores for extroversion and the IBS-SI scores.
