Problem: Alice was furious when CPS showed up at her door. She suspected her neighbor called in a report since they have been fighting all summer. The caseworker acknowledged Alice's anger and asked if they could sit down and talk. The caseworker already spoke with the child (Beth) at school and the child confirmed that both of her parents hit her. Beth showed the caseworker a mark behind her ear. She stated that her mother threw a book at her because she did not put it where it belonged. Beth also had fingerprint bruising on her arm from her father grabbing her. Their older son Mark (age 17) recently moved out because of physically fighting with his father. What type of intervention does this family require?
a. Primary
b. Secondary
c. Teritary
