Once the cause of stress has been identified, there are no behaviors that can lessen the effect of or eliminate the stress.

That statement would be false.

After we identified the cause of stress we can change our behavior to lessen or eliminate the effect of the stress.

Example , if someone experience a stress because of his Job, he can join a stress management class or he can go and do more social activities with those he loved. This will lessen or even diminish the stress that he feels at his workplace
