Questioning techniques in forensic interviews make a critical contribution to the
amount and quality of children's testimony (Lamb, La Rooy, Malloy, & Katz, 2011). Best
practice recommendations advise that interviewers ask predominantly broad open-ended
prompts (invitations and cued-invitations), minimise focused (direct) and closed-ended
(option-posing) prompts, and avoid suggestive questions (Orbach & Pipe, 2011). Deviation
from these recommendations is common, and deterioration in interviewing practice over time
is typical unless interviewers received regular practice focused supervision and feedback
(Lamb, Sternberg, Orbach, Esplin, & Mitchell, 2002). However, interviewers' access to
supervision is often limited (La Rooy, Lamb, & Memon, 2011). Guided self-review may be
an effective method to complement traditional face-to-face supervision. This thesis
examined: 1) forensic interviewing practice with children in New Zealand, 2) factors that
influenced practice, 3) forensic interviewers' perceptions of supervision, and 4) the
effectiveness of a self-review tool designed to increase the use of invitations and cuedinvitations.
