| Abstract: | This study examines the intercoder reliability of Rorschach Comprehensive System (CS; Exner, 2001) protocol-level variables. A large international sample was combined to obtain intercoder agreement for 489 Rorschach protocols coded using the CS. Intercoder agreement was calculated using an Iota coefficient, a statistical coefficient similar to kappa that is corrected for chance. Iota values for the variables analyzed ranged from .31 to 1.00, with 2 in the poor range of agreement, 4 in the fair range, 25 in the good range, and 116 in the excellent range of agreement. Discrepancies between variables are discussed. |
