The Bristol Stool Form Scale (BSFS), a frequently used measure in gastroenterology practice and research, categorizes stools into one of seven stool types ranging from type 1 (hard lumps) to type 7 (watery diarrhea). Inter-rater and intra-rater reliability of the BSFS by Rome III clinical categorization decreased with intraclass correlations of 0.75 (95% CI: 0.69 – 0.81, P<0.001) and 0.65 (95% CI: 0.49 – 0.81, P<0.001) respectively. type 6 stools, representing the boundaries of normal vs. These 13 photographs were rated by the majority of raters as either type 2 vs. However, agreement decreased when using Rome III designations, with 13 (37%) photographs having significantly diverging classifications (semi-interquartile range=0.5). Inter-rater and intra-rater reliability of the BSFS by individual stool type was excellent with intraclass correlations of 0.88 (95% CI: 0.86–0.90), P<0.001) and 0.89 (95% CI: 0.86–0.91, P<0.001) respectively. Though only 4 photographs had absolute agreement (all Type 1 or Type 7), general agreement was high with 1132 (95.1%) of ratings being within one category type of the modal rating. 1190 individual stool type ratings were completed.
