To replicate the Luton pilot study (Andrews et al., 2011), both by investigating treatment changes using the Human Givens (HG) approach via a practice research network (PRN) and by assessing the viability of replacing the 34-item Clinical Outcome in Routine Evaluation Outcome Measure (CORE-OM) with the ten-item version (CORE-10).

Clients were included if they were offered the HG approach to manage psychological distress and attended at least one measured treatment session following their initial assessment. Pre-post treatment effect size (Cohen's d) was benchmarked against data from Clark et al. (2009). Potential differences in treatment effects based on type of termination (planned vs unplanned) and medication use were examined.

High correlation between the CORE-10 and CORE-OM and near-identical calculated effect sizes support the utilisation of CORE-10 as a routine outcome measure. Pre-post treatment effect size suggests that clients treated using the HG approach experienced relief from psychological distress.

There was no experimental control nor evidence about the precise components of the HG treatment. Data on problem description and duration may not be reliable.

This larger study, involving thousands of cases in a wide variety of settings, reinforces the findings from the pilot study as to the plausibility of the HG approach in the relief of emotional distress.

The viability of using a ten-item scale to reliably measure treatment effectiveness will allow organisations to assess the quality of their treatment with minimal disruption to their service delivery allowing for true evidence-based practice. A PRN provides a suitable mechanism to assess psychotherapy treatment effectiveness in real-world settings.

The purpose of this paper is to investigate the treatment effects of Quest cognitive hypnotherapy (QCH) on anxiety and depression, and make comparisons with published data from the Improving Access to Psychological Therapies (IAPT) project.

Adult clients of QCH therapists were invited to enrol in a Practice Research Network (PRN) and completed pre- and post-therapy measures of anxiety (GAD-7) and depression (PHQ-9).

Post-treatment scores were available for 83 of the 106 clients reaching caseness (above the clinical cut-off on either or both measures) on their pre-treatment scores. Totally, 59 clients had moved to recovery, representing 71 per cent of cases where post scores were available and 56 per cent of the intent to treat (ITT) population (106 clients). Additionally, including all cases (both above and below cut-offs) 118 clients had post-treatment measures. In total, 86 (73 per cent) clients improved reliably. The mean number of treatment sessions was between three and four. This compares favourably with 2012-2013 IAPT findings using the same measures.

This study was exploratory involving a client group paying privately for treatment. There was no randomised control group or attempt to evaluate the effectiveness of specific components of therapy.

QCH may offer a brief effective treatment for clients with clinically significant levels of anxiety and/or depression, widening client choice.

As the first study to explore the effectiveness of private QCH this study offers an example of how to use a PRN to compare with published IAPT data using the same measurement tools.
