The Regulation Model
Sierra’s clinical model
This is the belief the whole programme is built on, and the reason we do not treat addiction with discipline, confrontation or shame.
The programme at Sierra Recovery is an adaptation of the methodology of PROMIS Clinics in the United Kingdom, applied to this centre. It treats addiction as a problem of regulation rather than of willpower: the substance or the behaviour is doing a job, usually managing a state the person cannot otherwise manage, and the work is to build something that does that job instead. In practice that means three structured therapy groups a day five days a week, individual therapy three times a week, and seventeen psychoeducation modules drawing on established therapeutic approaches. PROMIS has treated addiction in the United Kingdom since 1986, and more than 5,000 people have been treated with the PROMIS method by Robin Lefever and PROMIS Clinics. The adaptation used here has not been independently validated as a distinct model, and we do not claim it has.
Almost everything written about addiction assumes a failure of will.
It is the oldest and least useful idea in the field. If addiction were a willpower problem, deciding would be enough, and everyone who has ever wanted to stop would have stopped. The people who arrive here have usually decided to stop many times.
What they have not been given is an explanation that fits what actually happens in their body.
What is actually happening is regulation.
A nervous system has learned, through repetition, that one specific behaviour reliably makes an unbearable internal state go away. Not because the person is weak, but because it worked. It calmed fear, it filled a silence, it stopped a feeling, and it did so faster than anything else available.
That is a learned regulation strategy. It is clumsy and it is expensive, but it is not irrational, and it does not respond to being told to try harder.
The loop, and the three places we interrupt it
Once addiction is seen as regulation, the shape of the problem becomes visible, and so does where treatment has to act. The relief is real, which is why the loop holds. The shame that follows is what closes it, because shame drives isolation, and isolation manufactures the next trigger.
The loop is not broken by willpower at the point of use. It is interrupted earlier, and later.
Recognise and redesign, before the trigger
Most of the work happens before the urge exists: identifying what actually sets it off, then changing the environment so that fewer decisions have to be made under pressure. Fewer decisions in a day leaves more capacity for the ones that matter.
Regulate the urge, rather than resist it
An urge is not a decision, and it rarely holds peak intensity for long. This is trained, not willed: paced breathing, sensory anchoring, grounding through the senses, and a written plan agreed in advance for the moment everything narrows. Nobody is asked to be strong. They are given something to do.
Meet what follows with understanding, not shame
Self-attack does not improve self-control, it weakens it. Shame sends people into hiding, and hiding is where the next episode gets built. The work on the inner critic, on perfectionism and on relapse is not softness; it is the part that stops the loop closing again.
What follows from this
A clinical position is only worth stating if it changes what you do. This one changes a great deal, including some things we deliberately refuse to do.
- NoConfrontation, or breaking people downShame is not a therapeutic tool here. It reliably produces concealment rather than honesty.
- NoWillpower languageNobody will be told they simply need to want it more.
- NoRelapse treated as failureA return to use is information about where support is still missing, and it is handled as such.
- YesStructure, every single dayThe day is planned in the morning and closed in the evening, because structure carries people on the days motivation is simply absent.
- YesThe trauma underneath, treated hereNot referred out to someone else while we handle only the substance.
- YesA plan that survives the homecomingRelapse is usually a homecoming problem, so the homecoming is built before anyone leaves.
What this model does not claim
It is not a cure, it is not a guarantee, and it is not a substitute for clinical assessment. It does not suit everyone: acute psychiatric presentations, high suicide risk and anyone needing hospital-level care need a different setting, and we say so at assessment rather than after someone has travelled. We publish no success rate, because there is no audited figure we could define and defend.
What it does is make explicit what we think is actually wrong, and what we therefore do about it.
