Objective To describe the development and validation of the 5-grade photographic IBSA Neck Laxity Scale. Methods The scale was developed from 2 real images, which led to the creation of 5 morphed images, representing different degrees of severity of laxity of the neck. For validation, a set of 50 images (25 real and 25 morphed) was created and sent for evaluation to 6 trained raters (physicians) in 2 rounds, 1 month apart. Raters had to assess each image according to the 5-image scale. Inter-rater and intra-rater reliability in both rounds was evaluated. Results As to intra-rater reliability, single rater kappa scores between 0.69 and 0.87, and a global kappa score of 0.78 were observed. Inter-rater agreement was measured by means of the intra-class correlation coefficient and scores higher than 0.85 were reported, indicating excellent reliability. Conclusion IBSA Neck Laxity Scale is a validated and reliable scale.
Objective: To describe the development and validation of the 5-grade photographic IBSA inner upper arm scale. Methods: From 2 real-life pictures, a scale made up of 5 morphed images showing increasing severity of inner upper arm laxity was created. For validation, a set of 50 images (half of which real and the other morphed) was developed and sent to 5 trained physicians in two rounds 30 days apart. Raters' task was to make a selection of each image according to the given scale. Inter-rater and intra-rater reliability were evaluated in both rounds. Results: As to intra-rater reliability, single-rater kappa scores between 0.74 and 1.00 and a global kappa score of 0.846 were observed, while inter-rater agreement was calculated with intra-class correlation coefficient reporting scores higher than 0.91, which indicate excellent reliability. Conclusion: IBSA inner upper arm laxity scale proved to be a validated and reliable tool.
