Abstract:

The current study tested the effectiveness of a compact (18 hour) and blended (involving online and face-to-face components) training course, adapted from a previously evaluated course found to be successful in fostering long-term change in interviewing skill. The compact course was developed by trimming the previous course to only include learning activities that empirically demonstrated improvement of interviewing skills. There were 41US forensic interviewers, with prior training experience, who took part in the research. Their interviewing habits were assessed using standardized mock interviews immediately prior to, and at the conclusion of training. A subset were assessed 9-24months later. Results demonstrated that, despite reductions in length and content, training was effective in the short term and the subset maintained trained behaviors up to 24months after completion. Results suggest that adjustments to training can be effective if the training remains founded on principles of human learning.
