Abstract

Criteria-Based Contents Analysis(CBCA) is a statement-analysis technique that determines the veracity of sexually abused child victims’ statements. It consists of the 19 criteria that are most likely to exist in statements of children who are telling the truth. This study examined the inter-rater reliability of nine CBCA experts working for the Korean Police Agency. The experts evaluated the existing 19 CBCA criteria with five child sexual abuse cases. They were also asked to make a final decision as to whether the children’s statements were reliable or not. The results showed that 11 out of the 19 criteria indicated adequate inter-rater reliabilities, with coefficients of criterion 2(Unstructured production), 8(Unusual details), 9(Superfluous details), 11(Related associations), and 14(Spontaneous corrections) being low. The agreement coefficient of the overall judgments of the reliability of the children’s statements was .511, showing an adequate level of reliability. The implications of these findings for the use of CBCA reports in making credibility decisions in the forensic contexts are discussed.
