Research shows that prevention is important because (1) maltreatment can be avoided and (2) abuse and neglect can lead to negative consequences such as depression, developmental delays (e.g., speech difficulties), and the greater risk of developing substance abuse during adulthood (APA, 2017; Teicher & Samson, 2016).

Return on Investment
Immediate and long-term economic impact of child abuse and neglect suggests that child maltreatment costs the nation as much as $258 million each day, or approximately $94 billion each year. 

• Reduced- health and mental health care costs; child welfare services; law enforcement and judicial system costs 
• Increased earnings of the child's family members
