Résumé

In the field of child sexual abuse (CSA) disclosure, many studies have been conducted on the impact of interviewers' questioning style, but few have examined the impact of interviewers' supportive comments on children's cooperative and reluctant disclosure of substantive details. This field study used a sample of children ranging from 4 to 13 years of age who have all disclosed CSA. The first objective was to examine if the interviewer's and the child's comments during CSA interviews would vary as a function of the use of the National Institute of Child Health and Human Development (NICHD) Protocol. The second objective was to identify the strongest correlates of the proportion of details disclosed by the children during forensic interviews. A total of 90 matched NICHD Protocol and non-Protocol interviews done by the same interviewers were audio-taped, transcribed, and coded using verbal subscales. The goal was to explore if differences exist between the interviewers' supportive and non-supportive comments as well as children's cooperative and reluctant statements during investigative interviews conducted prior to or after the NICHD Protocol training. Results of a MANCOVA showed that the use of the NICHD Protocol had no influence on interviewers' and children's demeanors. A hierarchical multiple regression analysis controlling for relevant variables (e.g., child's age and NICHD Protocol) showed that children's reluctance and interviewers' non-support were associated with a lesser proportion of details. Overall, these results indicate that in order to promote detailed disclosure of CSA, interviewers should decrease their non-supportive comments and learn to deal more effectively with children's reluctance during forensic interviews. As such, protocols and training should encourage investigative interviewers to devote more time identifying early signs of children's verbal reluctance and to understand the negative impact of non-supportive comments on the disclosure of substantive details.
