Rapport building with adolescents to enhance reporting and disclosure

•Adolescents provided more information about a prior experience when interviewers disclosed information about themselves during rapport building, especially younger adolescents.•Rapport building facilitated disclosure of objective, timeline details in particular.•Rapport building was effective in eliciting more information about both positive and negative salient experiences. Adolescents comprise a vulnerable population that is exposed to crime and also may be reluctant to disclose full details of their experiences. Little research has addressed effective ways of increasing their willingness to disclose and provide complete reports. Strategies that improve honesty and report completeness in other age groups have not been evaluated to determine whether they are similarly effective at increasing adolescents’ reporting. In the current study, we tested whether rapport building techniques, modified from those commonly used with children and adults to address reasons why adolescents are likely reluctant, enhance the amount of detail adolescents provide about prior experiences. The participants, 14- to 19-year-olds (N = 125), completed an online questionnaire regarding significant events (e.g., big argument with family member) they experienced during the last 12 months. After a delay, they completed a remote interview asking them to recount details of one of the events. The interview began with either standard rapport building composed of largely yes/no questions about the adolescents’ background or one of two expanded rapport building phases: open-ended (questions about the adolescents’ backgrounds that required narrative answers) or enhanced (open-ended questions paired with the interviewer also sharing personal information). Although only adolescents in the standard condition showed age-related increases in information disclosed, overall adolescents in the enhanced condition provided significantly longer and more detailed narratives than adolescents in the other conditions. This effect was largest for the youngest adolescents, suggesting that mutual self-disclosure may be especially beneficial for eliciting honest complete reports from adolescents about salient prior experiences.
