Do I need to request permission to use Beck Depression Inventory and Beck Anxiety Inventory or I can simply use them since they are available in the public domain. How I can decide that any given survey is in the public domain or not ?!
how can i get the permission to use the Beck depression inventory tool as i require it for my dissertation work? please help me to get a solution for getting the permission.
If it has already been psychometrically tested in your country, you can use it, otherwise, you must send a message to the medical author and designer and get permission to psychometrically test it.
