Ej. Aucone et al., Reliability of the Advanced Psychodiagnostic Interpretation (API) scoring system for the Bender Gestalt, ASSESSMENT, 6(3), 1999, pp. 301-303
This study assesses the interrater reliability of the revised Advanced Psyc
hodiagnostic Interpretation (API) scoring system for the Bender Gestalt Tes
t (BGT). The API scoring system identifies 207 possible distortions in a BG
T protocol. Agreement across nine raters exceeded 90% for each of three cli
nical protocols. Kappa statistics indicated that the API system exhibited g
ood interrater reliability. Further research is necessary in such areas as
test-retest reliability and validity to further demonstrate the effectivene
ss of the procedure.
