Overview

Training evaluation demonstrates adherence to evidence-based interviewing protocols among police officers, highlighting the value of structured training courses.

Key Points

To evaluate the use of evidence-based investigative interviewing techniques across the Engage and explain, Account, and Closure phases among police officers before and after training.
Assessed 28 mock witness investigative interviews conducted by 14 experienced police officers, half of whom had prior evidence-based interviewing training.
Scored adherence across interview phases using a 14-component grid of recommended evidence-based techniques.
Officers used an average of 11.2 out of 14 recommended interviewing components following the completion of training.
Post-training performance was comparable regardless of whether officers had received prior evidence-based interviewing training.
