Cultural phenomena are significant behavioral representations of particular groups. Likewise, police culture is an essential embodiment of police organization. As a core topic of the current police culture, trauma has a profound impact on the physical and mental health of the police. Considering this, disclosing the traumatic experience of externalized police officers and helping them visualize the problem situations they are facing through specific means and methods of expressive writing, such as personal diary, creative writing, emotional letters, cases, and reflection, can well help them get rid of their physical and mental troubles and face work and life in a healthy and positive state.
