Hi there. I want to ask if there are any other suggestions about how to choose scales for our reduce-physical-aggression programs? Besides the Pubertal Development Scale.

No problem.

Thank you for the detailed reply.

Of course, you need to find the scales for measuring aggressive tendencies and anger status. Maybe the Reactive-Proactive Aggression Questionnaire and the child/adolescent version of the State-Trait Anger Expression Inventory are two good choices for you to consider.

You could find the below for more details:
