What Is Dual Diagnosis?
Dual diagnosis, or co-occurring disorders, is when an individual is dealing with a mental health disorder such as anxiety, PTSD, depression, or a personality disorder, in addition to a diagnosis of Substance Use Disorder.
Dual diagnosis is very common amongst those who suffer from addiction, with the underlying mental health or co-occurring disorder often fuelling addictive behaviours. It is important that co-occurring disorders are treated at the same time as addiction, as part of a comprehensive treatment programme, to increase the possibility of successful recovery.
Common Co-Occurring Disorders
The underlying mental health condition often fuels the addiction, while the addiction worsens the mental health condition — creating a cycle that requires integrated treatment to break.

What Our Clients Say
Real stories from people who have transformed their lives at One Step Rehab
One Step Rehab truly changed my outlook on life after recently spending 6 proactive and fulfilling weeks at One Step, Chiang Mai. I received first-class counselling and advice throughout my stay, delivered with care, insight, and real expertise.
To all the amazing staff at one step. Thank you for helping me through my toughest days. Your program has given me hope and a fighting chance to remain sober a facilities. Friendly and experienced counsellors will help you achieve sobriety if you let them.
I sent my son to One Step Thailand when we were looking for a rehab program that could support both his recovery and his passion for fitness. The well-equipped training facility was a huge factor for us, and it turned out to be just as important to his progress as the therapy itself.
I recently spent 4 months at One Step and can honestly say it was one of the best decisions I ever made. I initially planned to stay for 1-2 months but the program and quality of care impressed me so much that I decided to extend and really try and get the most professional input and clean time under my belt as possible.
I spent 5 weeks in treatment at One Step, I was originally meant to stay for 4 weeks however I needed more and could have stayed for 6, I personally think 6 should be minimum. The reason being, there is so much to take in and learn, adapt to and I only started to really feel a change in my brain on the 4th week.
I had an incredible experience at One Step Rehab. From the moment I arrived, I felt genuinely cared for and supported. The group sessions provided a sense of community and understanding, while the one-on-one counseling sessions allowed me to dive deeper into my personal journey with the help of compassionate and knowledgeable staff.
