Orange County Detox & Rehab Center - Drug & Alcohol Addiction Treatment California

Dual Diagnosis Treatment at Oasis Treatment Centers

Comprehensive care for addiction and mental health disorders.

At Oasis Treatment Centers, we specialize in treating individuals facing both substance use disorders (SUD) and co-occurring mental health conditions—a combination known as dual diagnosis.

This integrated approach is essential, as treating addiction without addressing the underlying mental health issues often leads to relapse and prolonged suffering.

We understand that true recovery means healing both the mind and body—and that starts with the right diagnosis and the right therapy.

What Is Dual Diagnosis?

Dual diagnosis refers to the presence of a substance use disorder alongside a mental health condition such as:

  • Depression
  • Anxiety disorders
  • Bipolar disorder
  • PTSD or trauma-related disorders
  • Personality disorders
  • Schizophrenia spectrum disorders

These conditions can feed into each other. For example, individuals may use drugs or alcohol to self-medicate symptoms of depression or anxiety, while long-term substance use can worsen or even trigger mental health disorders. That’s why treating both simultaneously is critical for a successful recovery.

The Role of Therapy in Dual  Diagnosis Treatment

Therapy is the backbone of dual diagnosis care at Oasis. Our licensed clinical team uses a combination of evidence-based and trauma-informed approaches that target both mental health symptoms and addictive behaviors. We meet each client where they are emotionally and mentally—providing individualized care that goes beyond symptom management.

Our approach includes:

Cognitive Behavioral Therapy (CBT)

CBT helps clients identify and change negative thinking patterns that contribute to both
substance use and mental health challenges. It’s highly effective in treating depression, anxiety,
and relapse triggers.

Dialectical Behavior Therapy (DBT)

DBT teaches critical skills like emotional regulation, distress tolerance, and
mindfulness—especially valuable for clients dealing with intense emotions, trauma, or
personality disorders.

Trauma-Informed Therapy

Many clients with dual diagnosis have histories of trauma. Our therapists are trained to address
these experiences with sensitivity, helping clients process pain without re-traumatization.

Medication Management

For clients who benefit from psychiatric medication, we provide on-site medication
management as part of the treatment plan. Stabilizing mood or anxiety disorders can
dramatically improve participation in therapy and long-term outcomes.

Integration with Therapy

Clients engage in both individual sessions for personalized healing and group therapy for peer
support, connection, and shared experiences that foster long-term growth.
