2015–2025: CELEBRATING 10 YEARS OF GROWTH, CARE, + HOPE
Since its founding in 2015, Odyssey Behavioral Healthcare has grown into a nationwide network of specialized mental health, eating disorder, and substance use treatment programs. United by a common mission, Odyssey provides individualized, high-quality care that supports long-term recovery at every stage.
Data that strengthens clinical excellence.
Behind every data point is a person, and behind every clinical decision is a commitment to delivering exceptional care. At Odyssey Behavioral Healthcare, we use empirical outcome measurement to continuously evaluate and strengthen our clinical programs, ensuring treatment remains individualized, evidence-informed, and responsive to each person’s needs.
Through our partnership with eBasis, we use validated assessment tools, including the BASIS-24® and EAT-26®, to measure treatment progress, identify trends, and guide ongoing clinical improvements. These insights help our teams refine care and support better long-term outcomes.
This commitment to continuous improvement is rooted in The Odyssey Way. Guided by our core values — Respect, Service, Flexibility, Collaboration, Accountability, and Integrity—we combine clinical expertise with measurable outcomes to provide compassionate, high-quality behavioral healthcare.
THE VALUE OF LONGITUDINAL DATA
Strong outcomes sustained year after year are the clearest evidence that treatment is working. Consistent results over time reflect care that adapts to each client’s progress and is refined to support effective, long-term recovery. Tracking outcomes across multiple years allows Odyssey to validate program effectiveness and continually strengthen the care it delivers

Drivers of Clinical Improvement
Significant, sustained symptom reduction reflects the consistent application of well-matched, evidence-based clinical interventions. When functional improvement scores rise steadily over time, it indicates that care is well-sequenced and aligned with each client’s developmental and motivational stage.

MEASURING POST-TRAUMATIC GROWTH IN VETERANS + FIRST RESPONDERS
In 2025, STR Behavioral Health launched Overwatch, a specialized mental health program for first responders and veterans that combines culturally competent care with a post-traumatic growth framework to support long-term recovery. The program also integrated the Post-Traumatic Growth Inventory (PTGI), a validated assessment that measures self-reported growth, not symptom reduction, across five domains following trauma.
Self-Harm Reduction
Among 31 participants with complete data, average scores rose from 77 at admission to 185 at discharge across core domain — an improvement of

Participants reported stronger relationships, deeper connections, and a greater capacity for vulnerability and trust with family, peers, and community.

Basis-24 ASSESSMENT
Odyssey Behavioral Healthcare uses the BASIS-24, a leading behavioral assessment instrument used to measure a broad range of symptoms and challenges across the diagnostic spectrum. The instrument includes 24 questions rated on a 5-point Likert scale and scored using a weighted-average algorithm to generate both an overall score and 6 subscale scores. These subscales assess key domains: depression, relationships, self-harm, emotional lability, psychosis, and substance use. The questionnaire is administered at admission, mid-treatment (or every 30 days), and again at discharge to evaluate progress and treatment effectiveness over time.
EAT-26 ASSESSMENT
Odyssey Behavioral Healthcare uses the EAT-26, a leading standardized self-report instrument used to measure eating disorder symptoms and related concerns. The assessment uses a six-point Likert scale and includes measures for behavioral symptoms and body mass index (BMI). It generates an overall score and three subscale scores: dieting, bulimia and food preoccupation, and oral control.

Odyssey Behavioral Healthcare uses a full battery of clinical outcome measurement tools to track progress, assess treatment e#ectiveness, and refine care throughout the treatment process. Grounded in current research, these tools provide objective insight across mental health, substance use, and eating disorder treatment, enabling the clinical team to adapt care and deliver strong clinical outcomes for every client.

Odyssey Behavioral Healthcare delivers individualized care across mental health, substance use, and eating disorder treatment. Its programs serve a range of ages and genders and address co-occurring conditions, with the specific populations and conditions treated detailed in each program’s information.

Odyssey’s facilities partner with most major insurance providers to offer coverage for mental health, substance use, and eating disorder treatment. Several programs also accept private pay and out-of-network benefits. Each client works directly with the admissions team to build a financial plan that fits both their clinical needs and financial circumstances.
