My study needs evaluation of aggressive behaviour in preschool children. For the purpose I want to use Overta Aggression Scale/Modified Overt Aggression Scale in my study. Could you please advise me on certain points........
Is OAS/Moas copyright by anyone?
If yes then what are the charges for research use?
How much time does it take in a single evaluation?
Can I can use OAS/MOAS? I am preschool teacher
