In a Series of Studies by Beutler and His Colleagues

In a series of studies by Beutler and his colleagues that compared the efficacy of Gestalt-based group therapy with cognitive or supportive/self-directed group therapies,they found that:

A) the three treatments differed with cognitive better than Gestalt therapy and both better than supportive/self-directed group therapy.
B) there were no differences between their effectiveness in any respect.
C) depressed patients did better in cognitive therapy,while non-depressed patients did better in Gestalt and supportive/self-directed therapies.
D) directive Gestalt-based therapies were a better match for low-resistant,internalizing clients,while self-directed therapies were more effective with highly resistant patients.
