Writing Alone or Together: Police Officers' Collaborative Reports of an Incident

Area of Science:

• Cognitive psychology
• Law enforcement procedures
• Information management

Background:

• Police officers often collaborate on incident reports.
• The impact of collaboration on report quality is not fully understood.

Purpose of the Study:

• To investigate how collaboration affects the quantity and accuracy of information in police reports.
• To identify factors that enhance information in collaborative police reports.

Main Methods:

• Eighty-six police officers worked in pairs on a training scenario, writing reports collaboratively or individually.
• A within-subjects design was used where officers wrote a second report collaboratively after an initial individual report.
• Content analysis of reports and discussion strategies were employed.

Main Results:

• Collaborative reports had less information than individually written reports, with no significant difference in accuracy.
• Officers who wrote individual reports before collaborating produced more accurate collaborative reports.
• Specific retrieval strategies during discussion positively correlated with information quantity in collaborative reports.

Conclusions:

• While collaboration may reduce information quantity, accuracy is maintained.
• Individual memory recall before collaboration and effective discussion strategies can improve collaborative report quality.
• Findings offer practical insights for police training and report-writing protocols.
