Start with the service and terminology
Begin with MVBH’s therapies dbt page, then review broader therapy services. These routes provide context for DBT and the wider therapy category. Co-occurring applications add a separate question: how the defined combination of mental health and substance use disorders relates to the DBT inquiry.
MVBH provides adult outpatient mental health care in Amesbury, Massachusetts for people exploring support related to dialectical behavior therapy. That fact establishes the organization, population, setting, location, and DBT-related exploration described by the source.
For this route, “co-occurring” has a specific boundary. It refers to the coexistence of both a mental health disorder and a substance use disorder. The definition does not, by itself, specify a DBT method, a program level, or a service arrangement. Keeping those questions separate prevents a broad term from being treated as a complete service description.
