When forensic interviewers reject children's "Don't know" responses, either by repeating questions or pressuring the children to provide different responses, children may change their subsequent responses. The primary objective of the current study was to examine interviewer reactions following preschool-aged alleged abuse victims' "Don't know" responses in 114 forensic interviews and the children's responses to these rejections. Interviewer reactions were dichotomously coded as either interviewer acceptance (i.e., transitioning to the next logical question or formulating questions focusing on previously mentioned details) or interviewer rejection (i.e., repeating questions or making negative remarks about recall ability). The results showed that the interviewers accepted the children's "Don't know" responses 75.3% of the time and rejected them 24.7% of the time. When interviewers rejected the children's "Don't know" responses, 75.9% of the subsequent responses contradicted the children's initial responses. These results suggest that interviewer rejections following preschool-aged children's "Don't know" responses may be suggestive.
