Striae distensae evaluation criteria have been recently described, but none is focused on objective striae assessment. With the purpose of better and objectively estimating the severity of striae distensae, the Objective Stretch Marks Assessment Scale has been developed by the authors' team.
Seven hundred White patients were included in the study and assessed. To assess the severity of striae distensae, abdomen, breasts, hips, gluteal area, back area, thighs, calves, and upper limbs photonumeric grading scales were developed. The Rasch model was used as part of the validation process. A score was attributed to each patient, based on the scales we developed. The interrater reliability and test-retest reliability were analyzed.
Eight photonumeric scales for striae distensae treatment outcomes assessment were developed. All scales exceeded criteria for acceptability, reliability and validity. The interrater and intrarater reliabilities were good, with a substantial or virtually perfect interrater reliability for the total score (P = 0.16).
The authors' results allowed them to validate the Objective Stretch Marks Assessment Scale as a reliable and reproducible tool to assess striae distensae treatment outcomes. This scale could be also considered as an important new metric that can be used in clinical research.
最近已经描述了伸展纹的评估标准，但没有一个标准专注于客观的伸展纹评估。为了更好地客观评估伸展纹的严重程度，作者团队开发了客观伸展纹评估量表。
本研究纳入了 700 名白人患者进行评估。为了评估伸展纹的严重程度，我们开发了腹部、乳房、臀部、臀区、背部、大腿、小腿和上肢的光电评分量表。验证过程的一部分使用了 Rasch 模型。根据我们开发的量表，为每位患者分配了一个分数。分析了组内和重测信度。
开发了 8 个用于评估伸展纹治疗效果的光电评分量表。所有量表均超过可接受性、可靠性和有效性标准。组内和组间信度良好，总分的组间信度为实质性或近乎完美（P=0.16）。
作者的研究结果证实了客观伸展纹评估量表是一种可靠且可重复的评估伸展纹治疗效果的工具。该量表也可以被认为是一个重要的新指标，可用于临床研究。
