A number of scientific studies have shown that EMDR is effective, for example, the prestigious Journal of Consulting and Clinical Psychology published research by Wilson, Becker and Tinker in December 1995. This study of 80 subjects with post-traumatic stress demonstrated that clients improved significantly with EMDR treatment, and further study showed that this beneficial effect was maintained for at least 15 months. The findings from this and other studies indicate that EMDR is highly effective and that results are long lasting.
