‘Best-practice’ guidelines for conducting investigative interviews with children are well established in the literature, yet few investigative interviewers actually adhere to such guidelines in the field. One of the problems is that little discussion has focused on how such guidelines are learned and sustained by professionals. To address this concern, the current article reviews the key elements of interview training programs that are known to promote competent interviewing. These elements include: (i) the establishment of key principles or beliefs that underpin effective interviewing, (ii) the adoption of an interview framework that maximises narrative detail, (iii) clear instruction in relation to the application of the interview framework, (iv) effective ongoing practice, (v) expert feedback and (vi) regular evaluation of interviewer performance. A description and justification of each element is provided, followed by broad recommendations regarding how these elements can be implemented by police and human service organisations in a cost-effective manner.
