DANA POINT, CA / ACCESS Newswire / March 19, 2026 / Alter Behavioral Health has published its 2025 Outcomes Report, presenting data from 1,888 clinical assessments conducted across intake, treatment, discharge, and post-discharge follow-up. The findings demonstrate sustained symptom reduction, strong substance use recovery outcomes, and durable functional gains in residential mental health treatment.
The report, independently audited by Pacific Analytics, uses validated clinical measurement tools including the PHQ-9 for depression, GAD-7 for anxiety, and the Personal Wellbeing Index to assess daily functioning and life stability.
Patients entered residential mental health treatment with an average PHQ-9 depression score of 12.56. By discharge, that number dropped to 6.89, reflecting an approximate 45 percent reduction in depressive symptoms. Post-discharge scores remained low at 7.86, representing a sustained improvement of roughly 37 percent compared to intake.
Anxiety outcomes followed a similar pattern. The average GAD-7 score decreased from 11.22 at intake to 6.24 at discharge, a 44 percent reduction in anxiety symptoms. Post-discharge anxiety scores remained stable at 6.89, reflecting a sustained 39 percent improvement from baseline.
Follow-up longitudinal analysis showed no statistically significant rebound in depression or anxiety symptoms after discharge. On average, follow-up outcomes were measured approximately two years post-discharge, with extended benchmarks tracked up to five years. This provides a meaningful indicator of long-term recovery rather than short-term symptom suppression.
Beyond symptom reduction, patients demonstrated measurable improvements in life satisfaction and daily functioning. Personal Wellbeing Index scores increased significantly from baseline to discharge, reflecting improved life satisfaction and functional stability. These gains remained above baseline levels at post-discharge follow-up, demonstrating sustained improvement in overall quality of life.
Among individuals receiving integrated dual diagnosis treatment for co-occurring mental health and substance use disorders:
-
93% reported reduced or no substance use since treatment
-
74% had no reentry into residential treatment after discharge
-
85% reported no emergency room visits in the prior 30 days
-
97% reported no law enforcement encounters in the prior 30 days
