How the MVBH service scope frames this question
Start with the dual diagnosis program to understand the verified service subject. The MVBH admissions route provides the next organizational context for questions about program categories.
MVBH describes dual diagnosis treatment as integrated care for adults with co-occurring mental health and substance use disorders. SAMHSA defines co-occurring disorders as the coexistence of a mental health disorder and a substance use disorder. Together, these facts establish the relevant service category without deciding whether social anxiety, alcohol use, or both meet diagnostic criteria.
The verified MVBH scope lists PHP, IOP, OP, Virtual IOP, and Dual Diagnosis. This confirms that PHP and dual diagnosis are recognized program categories. It does not show that every dual diagnosis question leads to PHP, or that mentioning social anxiety and alcohol use establishes entry into any category.
