The effects of intensive training and ongoing supervision on the quality of investigative interviews with alleged sex abuse victims

Four distinct strategies were employed to train 21 experienced forensic interviewers to interview alleged sex abuse victims (M=9.20 years of age) in accordance with professionally recommended practices. The structure and informativeness of the 96 interviews they conducted following training were compared with the structure and informativeness of 96 matched interviews conducted by the same interviewers in the 6 months prior to the training. Didactic workshops and instruction in the utilization of highly structured presubstantive interview procedures had little effect on the number of open-ended prompts used to elicit information or on the amount of substantive information elicited in this way. By contrast, intensive training in the use of a highly structured interview protocol, followed by continuing supervision in the form of monthly day-long seminars, supplemented in some cases by detailed individual feedback on recent interviews, yielded dramatic improvements on these measures of interview quality.
