Regular supervision influences interviewing quality with child witnesses. It is unclear, however, whether interviewers recognize the importance of supervision, and how often they access it. The present study surveyed 39 New Zealand Specialist Child Witness Interviewers (otherwise known as forensic interviewers), and examined: (a) their access to, and, perceptions of supervision, and (b) factors that may influence their access to, and, perceptions of supervision. We identified 26 interviewers who received some form of practice-focused supervision. Within this group, there was considerable variability in terms of how often they accessed supervision, and, their ratings of how satisfied they were with their access to, and the content of, supervision. Furthermore, some of those who did participate in supervision felt they did not actually receive specific input about their interviewing. Thus, an important area for investment in promoting good interviewing practice is developing effective approaches to facilitate interviewers engaging in regular practice-focused supervision, perhaps, at least in part, by addressing some of systemic barriers identified (e.g. limited financial support, time constraints, lack of experienced supervisors, lack of understanding/support from managerial staff and geographical isolation).
