Which of the following is NOT a criterion for discharge from outpatient treatment?

In the context of outpatient treatment, criteria for discharge typically revolve around the client's well-being and ongoing support needs. A client demonstrating improvement in mental health is essential for determining if they are ready to transition out of outpatient care. This shows that their treatment goals have been met to a satisfactory degree. Similarly, having a stable living environment is crucial, as it suggests a support system and reduces stressors that might impede recovery. Additionally, the client's willingness to participate in follow-up sessions indicates a continued commitment to maintaining their mental health post-discharge.

Since all the aforementioned points are essential for positive discharge outcomes, the option indicating that all of these criteria are NOT a criterion for discharge is correct. Each of these factors contributes to ensuring that the client is genuinely prepared for discharge and has the resources and support necessary for ongoing recovery.
