The Dodo Bird Verdict } But… some people disagree } Rachman & Wilson (1980) } “If the indiscriminate distribution of prizes argument carried true conviction…we end up with the same advice for everyone – Regardless of the nature of your problem seek any form of psychotherapy . This is absurd. We doubt whether even the strongest advocates of the Dodo bird argument dispense this advice”
Research Against the Dodo Bird Crits-Christoph (1997) critique } Virtually all of the bona fide treatments Wampold included in his study were CBT programs
Research Against the Dodo Bird } Smith, Glass, & Miller (1980) } Cognitive and CBT highest (1.31 & 1.24) } Behavioral and psychodynamic (0.91 and 0.78) } Humanistic (0.63) } Developmental (vocational-personal development counseling and "undifferentiated counseling ) (0.42). } …Compared to some “no-treatment” control

The client fears that she will be contaminated by dirt and germs and avoids touching anything in public places. She brings kleenex with her to wrap over her hand if she has to touch something.

Include a description of what you will do and how it’s supposed to work. } 2) Once you tell her about exposure, she is terrified to start. What might you say to calm her fears?
