Nidotherapy is a treatment developed by British psychiatrist Peter Tyrer that works on the environment rather than the person. It systematically changes a client’s physical, social, and personal surroundings to fit their personality, rather than trying to change the personality itself. It’s aimed specifically at people who haven’t responded fully to conventional treatment.
Nidotherapy does have a modest independent evidence base of its own, including a handful of published randomized controlled trials. However, it’s smaller and less established than the evidence behind treatments like DBT or mentalization-based therapy. That is worth keeping in mind when deciding where it fits in a treatment plan.
Both books here come from Tyrer, who originated the concept.

Nidotherapy: Harmonising the Environment with the Patient
Peter Tyrer, RCPsych Publications, 2009
This is the original general introduction to nidotherapy. It makes the argument for why chronic, treatment-resistant mental disorders often respond better to systematic environmental change than to further attempts at symptom-focused treatment. The book works through who nidotherapy is for, how to apply it, and how to carry out environmental analysis in practice, illustrated with case studies and exercises with answers, and closes with a chapter on who is qualified to practice it. It’s aimed broadly at chronic mental illness rather than any single diagnosis.
Tyrer is emeritus professor of community psychiatry at Imperial College London, with over 600 published articles spanning anxiety, depression, and personality disorders. He continues to work with NIDUS-UK, a charity built around the treatment he developed.
This is the place to start for understanding the concept before seeing it applied to a specific population. It predates the more targeted personality-disorder book below.
Adaptive Solutions to Personality Disorders: Treating Patients with Nidotherapy
Peter Tyrer, Routledge, 2025
Sixteen years on from the original book, this one narrows the focus specifically to personality disorders. It examines how to match a client’s environment to their personality profile, how to modify that environment once matched, and how to help the client adapt where the environment itself can’t change. It also updates the framework to use ICD-11’s classification of personality difficulty and severity, and adds a chapter connecting nidotherapy to social prescribing.
This is the more directly useful entry for clinicians working with personality-disordered clients specifically. The earlier book is broader, but less current on classification and less specific to this population.
