Quotin from the article:

In addition, the therapists ask the parents to find opportunities to explicitly tell their child something like, "Don't worry about this now; you will be able to do this when you get older," a pressure-reducing antecedent that can actually speed up compliance.

I found this rather amusing, it's straight out of Dr. Spock. It helped us wean our daughter from sucking her thumb, and was a great help for us in coping with many less than desirable behaviors in our kids. Just proves that sometimes the old way is the best way.
