Treatment Outcomes

There is a strong evidence base to support the treatment methods used at Castle Craig and in support of residential rehabilitation treatment for addiction

Castle Craig has not only academic and theoretical backing for its treatment programme, but it also has mounting evidence for its own outcomes. Very few treatment services can show this depth of support for their methods.

A successful treatment programme for addictive disease needs structure because so often in the lives of our patients there is no structure. The drug dictates how they live their life.

Castle Craig employs some of the leading authorities on the subject of alcohol and addiction. In addition to following the latest developments and research in our sector, we attend and present at conferences and commission our own research. Because of our high reputation, the media often seeks out staff opinions and contributions.

There is a vast body of evidence to show that residential treatment for addictions can enable people to lead drug-free lives.

At Castle Craig, we strive to provide the highest standard of treatment, and the results show that our treatment is effective.

In this section of the website, we are making available a number of addiction treatment research reports that we think are relevant to those interested in learning more about the disease of addiction and seeing the detailed evaluations of Castle Craig Hospital.

How Can Castle Craig Help?

How Do I Pay For Rehab?

One concern we sometimes hear from people is how they will fund their rehab treatment. The cost of rehab varies depending on what kind of accommodation you choose. You can pay for treatment at Castle Craig privately, or through medical insurance, and some people receive funding through the NHS.

How Long Is the Rehab Programme?

Residential rehab treatment starts at 4 weeks and can go up to 12+ weeks. Research shows us that the longer you stay in rehab and are part of the residential therapy programme, the longer the likelihood of continued abstinence and stable recovery.

Who Will I Speak to When I Call?

When you call you will reach our Help Centre team who will give you all the information you need to help you decide whether to choose treatment at Castle Craig. Once you have decided that you would like to have a free screening assessment you will be put in touch with our admissions case managers who will guide you through the admissions process.

What Happens at the End of My Treatment?

Castle Craig thoroughly prepares patients before departure by creating a personalised continuing care plan which is formulated following discussions with the medical and therapeutic team. We offer an online continuing care programme which runs for 24 weeks after leaving treatment, in order to ensure a smooth transition back into your everyday life. Patients leaving treatment automatically join our Recovery Club where they can stay connected via our annual reunion, events, online workshops and recovery newsletters.
