Situational Factors Impacting Harmful Behavior Towards Others Related to Mental Health in the Community and Their Associations: A Scoping Review Based on Systematic Reviews.

Background/objectives: This study aimed to identify factors associated with harmful behavior toward others based on existing research.

Methods: This scoping review focused on individuals at risk of harming others due to mental health issues, with the target population encompassing three settings: the community, inpatient facilities with frequent admissions and discharges, and healthcare settings where medical treatment is sought. A scoping review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. The terms violence, aggression, problem behavior, and workplace violence were used to search for related literature, subsequently selecting systematic reviews.

Results: A total of 24 papers were ultimately included. From the included papers, background factors (demographic, personal history, and clinical aspects); situational factors (social connection status, daily life status); psychological factors; antecedents of harmful behavior; and triggers of harmful behavior were extracted as factors associated with harmful behavior.

Conclusions: Our results indicate that background and situational factors lead to harmful behavior toward others, disruptions in the harmony between these factors cause disturbances in psychological processes, and harmful behavior toward others is triggered by stimuli that promote such behavior. Considering that all studies reviewed herein involved inpatients and forensic patients in medical settings, further research is required to identify the factors associated with harmful behaviors occurring in the community.
