Methods & Results.
A transparent account of the NHS Shropshire-partnered evaluation: who took part, how the evidence-based psychoeducation programme was delivered, how GAD-7 outcomes were analysed, and what changed.

NHS Shropshire-Commissioned Programme Outcomes Evaluation
Martin Jensen — Kingston University / University of Copenhagen · Commissioned through NHS Shropshire
TRT™ Therapy is a structured evidence-based psychoeducation programme for people experiencing anxiety-related conditions. This outcomes evaluation examined participant-reported change among people who followed the programme as directed, using the internationally validated GAD-7 scale.
Evaluation Design & Participant Selection
Participants were selected on the basis that they had followed the psychoeducation programme as directed. Of 100 invitations, 61 agreed to take part in the outcomes evaluation.
Internationally validated anxiety scale (Spitzer et al., 2006)
Wilcoxon signed-rank test for non-parametric ordinal data
Participant-reported GAD-7 scores before and after the programme
Reported Reduction in Anxiety Severity
The mean pre- and post-programme GAD-7 scores for participants were 18.28 and 2.84 respectively. A large proportion of participants reported scores in the severe range before the programme; the post-programme mean was within the minimal range.
A Wilcoxon signed-rank test found a statistically significant pre-to-post change in participant-reported anxiety symptoms (Z = −6.802, p < .001).
Pre-Programme Distribution
Mean: 18.28GAD-7 score category at program entry (n = 61)
Minimal (0–4)
Mild (5–9)
Moderate (10–14)
Mod. Severe (15–18)
Severe (>18)
Post-Programme Distribution
Mean: 2.84GAD-7 score category after completing the program (n = 61)
Minimal (0–4)
Mild (5–9)
Moderate (10–14)
Mod. Severe (15–18)
Severe (>18)
* GAD-7 categories: 0–4 Minimal · 5–9 Mild · 10–14 Moderate · 15–18 Moderately Severe · >18 Severe. Score <5 considered within normal range.
"Participants, many of whom reported severe anxiety symptoms pre-treatment, improved significantly using TRT™ Therapy program for anxiety elimination."

What the Evaluation Supports
The reported post-programme mean of 2.84 places the average evaluated participant within the GAD-7 “minimal anxiety” range. The findings document the change reported by participants who followed the evidence-based psychoeducation programme.
