Co-occurring Disorder Treatment

Integrated treatment for clients living with more than one diagnosis, addressed within a single treatment plan.

Most people who enter behavioral health treatment are living with more than one diagnosis. Co-occurring disorders — also referred to as dual diagnosis — are common among individuals with mental health conditions, substance use disorders, and eating disorders. Odyssey Behavioral Healthcare’s treatment brands are equipped to treat co-occurring presentations within integrated clinical frameworks rather than addressing each condition separately.

What Are Co-occurring Disorders?

Co-occurring disorders refer to the presence of two or more behavioral health conditions in the same individual at the same time.

These conditions interact and influence each other, so treating one in isolation often produces incomplete or short-lived results. Effective treatment for co-occurring disorders requires an integrated approach. The same clinical team must assess, address, and manage all conditions within the same treatment plan.

Common examples include:

  • Depression alongside a substance use disorder
  • An eating disorder alongside anxiety or trauma
  • PTSD alongside substance use
  • A personality disorder alongside a mood disorder
  • An eating disorder alongside a substance use disorder
  • Bipolar disorder alongside a behavioral addiction

Odyssey’s Approach to Co-occurring Treatment

Odyssey's approach to co-occurring disorders is built on a core clinical principle: if the conditions exist together, treat them together.

Across all brands that treat co-occurring presentations, clinical programming integrates assessment, treatment planning, and intervention for each condition simultaneously. Treatment plans address the full clinical picture from day one rather than sequencing conditions or referring clients to separate programs for each diagnosis.

This approach includes:

  • Integrated assessment at admission to evaluate all presenting conditions

  • Unified treatment planning to address the interaction between diagnoses

  • Clinical teams with expertise across multiple diagnostic areas

  • Coordinated psychiatric medication management when multiple conditions require it

  • Ongoing reassessment as the clinical picture evolves during treatment

Frequently Asked Questions

What are co-occurring disorders?

Co-occurring disorders — also called dual diagnosis — happen when a person lives with two or more conditions at the same time, such as a mental health condition alongside a substance use disorder or an eating disorder. These conditions affect each other, so treating only one often leads to incomplete or short-lived results. Effective treatment addresses all conditions together, with one clinical team managing them in a single treatment plan.

How does Odyssey treat co-occurring disorders?

Odyssey’s treatment brands address co-occurring disorders within integrated clinical frameworks. All presenting conditions are assessed at admission, and treatment planning addresses the full clinical picture from day one. Clinical teams work across diagnostic areas rather than treating each condition in a separate program, and they reassess treatment plans as the clinical picture evolves during care.

Which Odyssey brands treat co-occurring disorders?

Co-occurring treatment is a clinical capability across the Odyssey organization, not limited to a single brand. STR Behavioral Health specializes in co-occurring mental health and substance use conditions. Clearview Treatment Programs and Lifeskills Behavioral Health also treat dual diagnosis conditions. Aster Springs and Magnolia Creek treat eating disorders alongside co-occurring mental health conditions. Pasadena Villa treats complex psychiatric conditions involving multiple mental health diagnoses.

What is the difference between co-occurring disorder treatment and treating conditions separately?

Treating co-occurring conditions separately means addressing one diagnosis at a time, often through different programs or providers. This approach often yields incomplete results because the conditions influence one another. Integrated co-occurring treatment addresses all conditions simultaneously within the same treatment plan, with the same clinical team from the start of care. Odyssey’s treatment brands use this integrated approach across all programs serving clients with co-occurring conditions.

What levels of care are available for co-occurring disorder treatment?

Odyssey offers co-occurring disorder treatment across residential, partial hospitalization (PHP), intensive outpatient (IOP), and virtual outpatient levels of care, with transitional living and supportive housing available at select facilities. The appropriate level of care depends on diagnosis, acuity, and the specific combination of conditions being treated. Odyssey’s admissions teams help match clients to the right level and brand based on their full clinical picture.

Does Odyssey treat eating disorders alongside substance use disorders?

Yes. Magnolia Creek treats clients with eating disorders alongside co-occurring substance use disorders within an integrated treatment plan that addresses both conditions simultaneously. For clients presenting with other combinations of eating disorder and substance use diagnoses, Odyssey’s admissions team evaluates the full clinical picture to determine the right treatment setting and level of care across the organization.

How does Odyssey measure the effectiveness of co-occurring disorder treatment?

Odyssey measures treatment effectiveness using validated assessment instruments, including the BASIS-24 for mental health and substance use outcomes and the EAT-26 for eating disorder outcomes. Odyssey benchmarks results against national norms and publishes them in annual clinical outcomes reports. For clients with co-occurring disorders, Odyssey evaluates treatment effectiveness across all presenting conditions, not just the primary diagnosis.
