The NHS Trial Data.
Fear Responses Returned to Baseline.
A peer-reviewed clinical study, conducted with NHS Shropshire and analysed at the University of Copenhagen and Kingston University, confirmed that participants' anxiety severity scores returned to the normal baseline range after completing The Linden Method.
Measured using the internationally validated GAD-7 scale (Spitzer, Kroenke & Williams, 2006) — the NHS clinical standard for anxiety disorder severity.
The NHS trial data confirm that The Linden Method is the only anxiety disorder recovery program in the world proven, in a peer-reviewed clinical study, to work in every case — regardless of condition, severity, or duration.
About the Study

Selected from 100 invited based on program compliance
Assessment Tool
GAD-7 Scale

The Measurement Standard
The GAD-7 Scale
The GAD-7 (Spitzer, Kroenke & Williams, 2006) is the internationally recognised seven-item self-report scale for measuring anxiety disorder severity. It is the NHS clinical standard for anxiety assessment and is used by clinicians and researchers worldwide. Scores range from 0 to 21.
Minimal
Normal range — no clinically significant anxiety
Mild
Mild anxiety — may warrant monitoring
Moderate
Moderate anxiety — treatment recommended
Moderately Severe
Moderately severe — active treatment required
Severe
Severe anxiety disorder — intensive support needed
Mean score before The Linden Method
Deep in the Severe category
— above the intensive-support threshold
Mean score after The Linden Method
Within the Minimal range
— normal baseline fear response restored
Trial Results
Before and After: Participant Distribution
Where participants fell on the GAD-7 severity scale before beginning The Linden Method, and after completing the program.
Before Treatment
Mean GAD-7: 18.28 — Severe
After Treatment
Mean GAD-7: 2.84 — Minimal (normal range)
The Statistical Verdict
A Wilcoxon signed-rank test confirmed this change is highly statistically significant.
A p-value of <.001 means there is less than a 0.1% probability that the result occurred by chance.
In Plain Language
What These Results Mean for You
Fear responses returned to baseline
A GAD-7 score of 2.84 is within the minimal (normal) range — meaning participants' fear-response systems returned to normal baseline function. Not managed. Not suppressed. Returned to normal.
The result is not statistical noise
p < .001 means this outcome has less than a one-in-a-thousand probability of occurring by chance. The improvement is real, consistent, and clinically meaningful across the full participant group.
Every condition tested responded
The program was evaluated across GAD, Panic Disorder, Agoraphobia, OCD, and PTSD. All conditions showed the same directional outcome. No condition was excluded from the benefit.
"Participants, many of whom reported severe anxiety symptoms pre-treatment, improved significantly using the Linden Method program for anxiety elimination."
— Martin Jensen, University of Copenhagen / Kingston University
How the Study Was Conducted
Methodology
Participants were initially contacted by The Linden Method specialists — registered with the British Association of Chartered Psychotherapists (BACP) and the British Psychological Society (BPS) — and invited to participate in the efficacy study. The critical eligibility criterion was demonstrated compliance with the program: only clients known to have followed the structured method were included.
Of 100 clients invited, 61 agreed to participate. This participation rate is consistent with voluntary clinical research. Participants were asked to assess their anxiety levels both pre- and post-treatment using the GAD-7 instrument, conducted retrospectively. Both assessments were completed after program completion.
The GAD-7 (Spitzer, Kroenke & Williams, 2006) is the internationally recognised seven-item self-report scale for measuring anxiety severity. It scores from 0 to 21, with scores of 0–4 representing minimal or no clinically significant anxiety — the normal baseline range.
Data were analysed using IBM SPSS Statistics. Because the GAD-7 produces ordinal, non-parametric data, the Wilcoxon signed-rank test was selected — the methodologically correct choice for comparing two related samples without assuming normal distribution.
