Nondirective (ND), applied relaxation (AR), and cognitive behavioral (
CBT) therapies for generalized anxiety disorder (GAD) were compared. T
he latter 2 conditions were generally equivalent in outcome but superi
or to ND at postassessment. The 3 conditions did not differ on several
process measures, and ND created the greatest depth of emotional proc
essing. Follow-up results indicated losses in gains in ND, maintained
gains in the other 2 conditions, especially CBT, and highest endstate
functioning for CBT. AR and CBT thus contain active ingredients in the
treatment of GAD; support exists for further development of imagery e
xposure methods or cognitive therapy because of their likely role in p
romoting maintenance of change with this disorder. Expectancy for impr
ovement was also associated with outcome, suggesting the need for furt
her research on this construct for understanding the nature of GAD and
its amelioration.
