What is the most effective technique to use with physically abusive parents?

When dealing with physically abusive parents, ignoring the behavior is not an effective technique as it may escalate the situation and put the child at risk of further harm. Recommending immediate removal of the child is also not the most effective technique as it may not address the root cause of the abusive behavior and can further traumatize the child by separating them from their family. Suggesting anger management courses may be helpful, but it is not the most effective technique as it may not address the underlying issues and may take time for the parent to see results. The most effective technique is to focus on the behavior and provide alternative methods of discipline that do not involve physical harm. This approach allows for open communication and understanding of the parent's behavior and encourages them to learn healthier ways of disciplining their child.
