The Bristol Stool Form Scale (BSFS) and a modified child-friendly version (M-BSFS) are frequently used in clinical practice and research. These scales have not been validated in children. 3-D stool scale models may be better adapted to the child's development.
To assess the usefulness of the BSFS, M-BSFS, and a newly developed 3-D stool scale in children.
Fifty children were asked to rank the picture cards of the BSFS and 3-D models from hardest to softest and to match the pictures with descriptors for each stool type.
Thirty percent of the children appropriately characterized the stools as hard, loose, or normal using the BSFS vs. 36.6% with the 3-D model (p=0.27). Appropriate correlation of stools as hard, loose, or normal consistency using the BSFS vs. the 3-D model by age group was: 6 to 11-year-olds, 27.5% vs. 33.3% (p=0.58) and 12 to 17-year-olds, 32.1% vs. 39.5% (p=0.41). Thirty-three percent correlated the BSFS pictures with the correct BSFS words, 46% appropriately correlated with the M-BSFS words, and 46% correlated the 3-D stool models with the correct wording.
The BSFS and M-BSFS that are widely used as stool assessment instruments are not user-friendly for children. The 3-D model was not found to be better than the BSFS and the M-BSFS.
布里斯托大便形态量表（BSFS）及其改良的儿童友好版（M - BSFS）在临床实践和研究中经常被使用。这些量表尚未在儿童中得到验证。三维大便量表模型可能更适合儿童的发育情况。
评估BSFS、M - BSFS和新开发的三维大便量表在儿童中的实用性。
让50名儿童将BSFS的图片卡片和三维模型从最难到最软进行排序，并将图片与每种大便类型的描述词进行匹配。
使用BSFS时，30%的儿童能正确将大便描述为硬、稀或正常，而使用三维模型时这一比例为36.6%（p = 0.27）。按年龄组划分，使用BSFS与三维模型对大便硬、稀或正常一致性的正确相关性为：6至11岁儿童，分别为27.5%和33.3%（p = 0.58）；12至17岁儿童，分别为32.1%和39.5%（p = 0.41）。33%的儿童能将BSFS图片与正确的BSFS描述词相关联，46%能与M - BSFS描述词正确关联，46%能将三维大便模型与正确的描述词相关联。
广泛用作大便评估工具的BSFS和M - BSFS对儿童来说并不方便使用。未发现三维模型比BSFS和M - BSFS更好。
