First developed by our team 32 years ago, the original therapeutic approach behind today’s Threat Recalibration Therapy™ (TRT™) was created around one purpose: recovery, rather than simply learning to live with anxiety.
The earlier work and today’s TRT™
Some earlier publications, interviews and participant accounts refer to Charles Linden’s work as the Linden Method. That is the historical name associated with the earlier programme. Today, the Institute presents its distinct recovery approach as Threat Recalibration Therapy™ (TRT™). Earlier accounts form part of that history; information on this website describes the Institute’s current approach and programme options.
Recovery remains the purpose
TRT™ is a distinct, non-clinical therapy—not psychotherapy, conventional psychological therapy or a self-help programme. Its threat-recalibration model focuses on faulty risk analysis and the threat-response patterns that sustain anxiety. A structured therapeutic process, practical recovery work and qualified support put that recovery-focused purpose into practice. Education is part of TRT™, not its identity.
The Institute today
The Institute is the official home of TRT™ and the place to find current programme information, research and practitioner accreditation. Its work spans predisposition assessment, prevention and recovery, with online, corporate, educational, workshop and residential programme options, alongside its work in sport.
Historical publications and programme evaluations should be read in their original context. Our research pages identify the work being discussed and the outcomes measured.
