AIMS ratings--repeatability

In the present study, two raters, a psychologist and a nurse, each made
five independent ratings of 30 different video-recorded patient-
examinations. Having thus excluded patient fluctuation, individual- rater
consistency and between-rater agreement over the 6 weeks of the study are
examined. While between-rater agreement was apparently being maintained,
mean AIMS scores steadily increased. In the hands of these raters, AIMS
items 2 and 4 emerged as very reliable, while items 1, 6, and 7 showed high
variability. Some patients appeared to be hard to rate. Differences between
the study raters and the author JB highlight the issue: how reproducible is
an AIMS rating?
