The NHS Shropshire-Partnered Outcomes Evaluation
The primary published evaluation of participant-reported outcomes for the TRT™ Therapy psychoeducation programme.
The programme was evaluated in an NHS Shropshire-commissioned study analysed by Martin Jensen (Kingston University / University of Copenhagen). The single-group pre/post evaluation used the GAD-7 with 61 participants across multiple anxiety diagnoses. Source: Jensen, M. Programme outcomes evaluation commissioned through NHS Shropshire.
Study Parameters
Core Statistical Result
18.28
Mean GAD-7 — Pre-Programme
Severe anxiety category (≥18)
84.5% reduction
Z = −6.802
p < .001
2.84
Mean GAD-7 — Post-Programme
Minimal anxiety (below threshold of 5)
Statistical analysis: The Wilcoxon signed-rank test evaluates pre- and post-programme GAD-7 scores for the same participants. The analysis produced Z = −6.802 and p < .001.
GAD-7 Score Distribution: Pre- and Post-Programme
Reported cohort distribution across severity categories before and after the programme.
