The current study explored the effectiveness of note-taking instructions to increase the completeness and accuracy of professionals’ contemporaneous written notes of child abuse interviews. Police members had their base-line note-taking assessed before receiving brief instructions focusing on layout style, abbreviations, and question codes. Participants’ note-taking was reassessed immediately post-instruction and again at follow-up, 4 weeks later. Instructions increased the number of questions that participants recorded and the information that they recorded about question structure. These increases in question information did not occur at the expense of witness response information. Instructions encouraged participants to use more abbreviations and question codes and to use a clearer layout style to differentiate questions and responses. Instructing professionals in simple note-taking strategies immediately increased the completeness and accuracy of their notes. However, electronic recordings remain the most effective method of ensuring complete and accurate interview notes.
