TL;DR: In this article, the authors investigated the effect of scale complexity and rater training on intra-rater reliability and found that neither rater experience nor scale complexity significantly influenced intra rater reliability.
Abstract: This article reports two studies which investigated the effect of scale complexity and rater training upon intra‐rater reliability. The results indicate that neither rater experience nor scale complexity significantly influenced intra‐rater reliability.

TL;DR: Assessment of inter‐ and intra‐rater reliability of GI transit times from 3D‐Transit recordings found some inherent variability in the measurements, which may be experience‐dependent.
Abstract: Background The 3D-Transit electromagnet tracking system is an emerging tool for the ambulatory assessment of gastrointestinal (GI) transit times and motility patterns, based on the anatomical localization of ingestible electromagnetic capsules. Currently, 3D-Transit recordings are manually analyzed to extract GI transit times. As this is a subjective method, there is some inherent variability in the measurements, which may be experience-dependent. We therefore assessed inter- and intra-rater reliability of GI transit times from 3D-Transit recordings. Methods Thirty-six 3D-Transit recordings (17 female; median age: 34 years [range: 21-80]) were analyzed twice by 3 raters with varying experience. Each rater manually identified the timestamps when a capsule progressed from antrum to duodenum, and from ileum to right colon. These timestamps, along with the ingestion and expulsion times, were used to determine whole gut (WGTT), gastric emptying (GET), small intestinal (SITT) and colonic (CTT) transit times. Reliability was determined using interclass correlation coefficients (ICCs). Key results For capsule progression timestamps, the most and mid-experienced raters had fair to good inter- and excellent intra-rater reliability (ICCmin-max = 0.61-1.00), whereas the inexperienced rater had poor to fair inter- and poor intra-rater reliability (ICCmin-max = 0.28-0.55). GET and SITT reliability between the most and mid-experienced raters was fair (ICCmin-max = 0.61-0.73), while reliability between these raters and the inexperienced rater was poor to fair (ICCmin-max = 0.28-0.55). CTT reliability was excellent between and within all raters (ICCmin-max = 0.92-0.99). Conclusions & inferences Inexperienced raters provide the least reliable measurements from 3D-Transit recordings, which confirms requirement for adequate training. Automation may improve the reliability of measurements.
