Final answer:
The ABCX model focuses on family dynamics, while the Double ABCX model considers dual stressors.
Step-by-step explanation:
The ABCX model and the Double ABCX model are both theoretical frameworks used to understand family stress and crisis. However, they have some key differences. The ABCX model focuses on the family dynamics and the interaction between stressors, resources, and the perception of the event within the family. On the other hand, the Double ABCX model takes into account dual stressors, which means it considers multiple stressors occurring simultaneously in a family's life.
