Distress evaluation scale for treatment (DEVS-T)


Construct:Distress, Therapeutic Technique, Treatment Distress Reactions Purpose:The purpose of the Distress Evaluation Scale for Treatment is to assess the distress and intrusiveness of the technique utilised during the therapeutic experience. Summary: The Distress Evaluation Scale for Treatment (DEVS-T; Devilly, 1999) is an 8-item, rationally based measure of the judgment of the actual therapeutic technique rather than of the therapist. It contains 8 items that are rated on a 9-point Likert-type scale, and it is administered/returned after the termination of therapy. In a study comparing Eye Movement Desensitization and Reprocessing (EMDR) and a Cognitive-Behavior Therapy (CBT) treatment variant (Trauma Treatment Protocol: TTP) in the treatment of posttraumatic stress disorder (PTSD), patients returned the DEVS-T at 2-week followup. Treatment distress, as assessed by the DEVS-T, displayed no differences between TTP and EMDR, as detected by an independent t-test. It was found that TTP was both statistically and clinically more effective in reducing pathology related to PTSD and that this superiority was maintained and, in fact, became more evident by 3-month follow-up.
