Maternal filicide refers to mothers killing their children. The document discusses different types of filicide including altruistic, psychotic, fatal maltreatment, unwanted child, and spouse revenge filicide. Common factors seen in filicidal mothers include crime location, victim characteristics, method used, and confession after arrest. Additional factors like age, education level, relationship status, and social circumstances are also considered. Prevention efforts include early screening for mental illness, helping at-risk mothers find meaning and significance, and understanding the motives and stressors that lead mothers to commit filicide. However, it is difficult to determine if a specific mother will commit filicide due to varying individual characteristics.
