Background: Human Givens (HG) Rewind is a relatively unknown trauma-focussed treatment. This paper aimed to provide preliminary evidence of the effectiveness of Rewind to treat posttraumatic stress (PTS) in a variety of clinical settings in Great Britain. Methods: An observational prospective design was used in each of the four studies. Standardised questionnaires were administered in every session. Pre- and post-treatment means and effect sizes were calculated for each study, as were ‘recovery rates’ and ‘reliable change’ rates. Results: Across four studies, a total of 274 clients completed treatment and had complete data. The data capture rate ranged from 80-100%. The mean pre-treatment scores were in the severe range. The pre-post treatment effects sizes ranged from 1.90-2.68. The recovery rate, or percentage of clients who were below the clinical cut-off after treatment, ranged from 46-56% for the more conservative lower cut-offs, and ranged between 71-82% for the higher clinical cut-offs as used by Improving Access to Psychological Therapies (IAPT). Across the four studies, 83-96% of clients had ‘reliably improved’ (88-94% on trauma-specific questionnaires), with 4-17% having no reliable change on those questionnaires. There was no ‘reliable deterioration’. The mean number of HG treatment sessions ranged from 5-6.5 sessions (range 1–24 sessions), with between 73% and 84% of participants completing treatment in six sessions or less. Conclusions: These preliminary results indicate that HG Rewind appears to be a promising trauma treatment in a variety of settings. A randomised controlled trial is now required to determine the efficacy of this treatment.
