Effects of the NICHD Protocol Training on Child Investigative Interview Quality in Korean Police Officers

This study was conducted to determine, by comparing pre- and post-training interview of 18 Korean police officers, whether training in use of the NICHD Protocol improved the quality of investigative interviews of allegedly abused child victims. Results showed that Korean police officers more often followed the Protocol structure -they introduced themselves, explained the ground rules, and conducted episodic memory training-after they had been trained. Moreover, police officers used approximately three times as many desirable prompts (such as invitations and facilitators) and fewer suggestive prompts in interviews conducted after as opposed to before the training. Invitations elicited approximately four to seven times more details on average than the least productive prompts. These results confirmed that the NICHD Protocol is effective when used to interview alleged child abuse victims in East Asia.
