I am opposed to the suggestion in this petition. It does not seem to recognize that Clinical Psychologists are licensed to practice independently.  Certainly I support quality assurance for Clinical Psychologists as for any  other professions, but several more proven methods already exist, such as acquiring and maintaining licensure, a responsibilty of the clinician to follow ethical and evidence based practices, and grievance procedures available to the consumer.  Pre-post measures are not always the most meaningful. As others have commented, any such standard measure would not take into account the diversity of clinical issues and patients' needs.  As a Clinical Psychologist I welcome patients' feedback about the therapy relationship and my direction of psychotherapy throughout the treatment process.   When treatment goals have been reached, termination review sessions offer another opportunity for individuals to assess their progress and satisfaction with treatment.  Finally, I agree with others' comments on the unnecessary financial burden and interruption of the therapeutic process with such a requirement.
