I am confused about the best way to set up this data for validity/reliability analysis: subjects are 52 teeth set individually in an artificial mandible (26 have a fracture and 26 are intact controls), an image of each tooth is made with two different types of equipment (call them T1 and T2), a software program produces the images on a screen and three different raters look at all 104 images in random order and rate them as: 1) definite fracture, 2) indefinite, 3) definite intact tooth. Then at 8 weeks the raters are provided the same images, again assorted randomly and asked to rate them. Can this be set up and analyzed in a mixed or factorial repeat measures design? Or must this be broken down to two separate problems: rater reliability and equipment validity?
