Peer-Reviewed Clinical Evidence
The Linden Method Works.
The Data Proves It.
A peer-reviewed clinical trial, conducted in collaboration with NHS Shropshire and data analysed at the University of Copenhagen and Kingston University, has confirmed that The Linden Method produces highly significant reductions in anxiety severity.
Participants moved from severe clinical anxiety to the minimal range — not as a managed outcome, but as a result of complete elimination of anxiety disorder symptoms.

Clinical Partner
NHS Shropshire
National Health Service, United Kingdom
Participants
61 Compliant Clients
Selected from 100 invited based on program compliance

GAD-7 Scale
Generalized Anxiety Disorder 7-item, the international standard measure

Statistical Method
Wilcoxon Signed-Rank Test

The Measurement
Understanding the GAD-7 Scale
The GAD-7 is the internationally recognised clinical standard for measuring anxiety disorder severity, used by the NHS and clinicians 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
Study participants' mean pre-treatment score
Deep in the Severe category — above the clinical threshold for intensive support
Trial Results
Before and After: Distribution of Participants
The charts below show where participants fell on the GAD-7 scale before beginning The Linden Method, and after completing the program.
Before Treatment
Mean GAD-7 score: 18.28 (Severe)
After Treatment
Mean GAD-7 score: 2.84 (Minimal — normal range)
The Statistical Verdict
A Wilcoxon signed-rank test confirmed that this change is highly statistically significant.
A p-value of <.001 means there is less than a 0.1% probability the result occurred by chance.
In Plain Terms
What These Results Mean for You
Severity dropped from Severe to Minimal
Participants began the study with a mean GAD-7 score of 18.28 — firmly in the Severe category. After completing The Linden Method, the mean score was 2.84 — well within the normal, minimal range.
The change is not statistical noise
A p-value of less than .001 means this result has less than a one-in-a-thousand probability of occurring by chance. The improvement is real, consistent, and clinically meaningful.
Multiple serious conditions all responded
The program was tested 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 et al., 2006) is the internationally recognised seven-item self-report scale for measuring anxiety severity. It scores from 0 to 21, with scores below 5 representing minimal or no anxiety disorder.
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.
