ABSTRACT
This study is a comparative
analysis of the effectiveness of four psychotherapeutic treatment modalities:
Cognitive-Behavioral Therapy (CBT), Eye Movement Desensitization and Reprocessing
(EMDR), Dialectical Behavior Therapy (DBT), and Hypnotic methods (HYP). The aim
of this study was to determine the independent effectiveness of the four
treatment modalities by reviewing the available literature. A total of 26,724
studies were identified by ProQuest search and screened to eliminate studies that did not permit
computation of the success rates of their use.
Of that total, 648
studies included objective data in some form, with 207 studies qualifying
for inclusion in the analysis. The “Success Rate”
measure was used as the standard of measurement, and was obtained by
comparing the pre-treatment scores with post-treatment scores as published in
the qualifying studies. Analysis revealed the most effective treatment
modality to be EMDR,with a success rate of 49.4%.
CBTwas the second most effective at 40.5%, and the
success rates of Hypnosis and DBT were 39.2% and 22.4% respectively. The clinical question
in therapy should probably be, “How effective can I expect this method of
treatment to be?” The
findings of this study reveal CBT to be less effective than EMDR and equally
effective as Hypnosis; and with DBT being significantly less effective, we are
left with the implication that we must expand what we know.
