We wanted to do something about improving mental health treatment outcomes for this very commonly encountered disorder.” Details appear in an early online issue of the Journal of Consulting and Clinical Psychology.
Westra, Constantino and Antony tested an idea based on preliminary research suggesting that therapists might improve CBT by addressing the observation that patients are very often ambivalent about giving up their worry and anxiety. Constantino says, “People can come into therapy both wanting to change and being reluctant to change. They may be reluctant to let go of something that is so familiar, something that serves as an adaptive tool.
