Outpatient mental health care

Outpatient mental health care refers to intensive behavioral health services that do not require an inpatient hospital stay. Outpatient care offers the benefits of mental health treatment while also allowing patients to return home at night and continue elements of daily living.

Outpatient services in Nashville, Tennessee

Using group therapy sessions, TriStar Centennial Parthenon Pavilion outpatient services work to equip adults with the knowledge, tools and self-awareness to effectively cope with difficult life experiences.

With an expert team of clinicians trained in psychiatry, social work, clinical counseling, art therapy, music therapy, yoga and pharmacy, the outpatient services are designed to offer a higher level of care to individuals 18 years old and older who need more support than the occasional outpatient therapy appointment.

Services we provide

The outpatient services of Parthenon Pavilion include an adult partial hospitalization, adult intensive outpatient program and adult evening intensive outpatient programing.

Outpatient services use a curriculum grounded in researched theories and evidence-based techniques. While the program is founded in cognitive behavioral theory, these services apply additional philosophies of care to best meet the individual needs of the client.

Other theoretical frameworks include:

  • Acceptance and commitment therapy
  • Behavioral activism
  • Cognitive-based mindfulness therapy
  • Internal family systems
  • Motivational interviewing
  • Trans theoretical model of change
  • Trauma-informed, person-centered care

Adult partial hospitalization program (PHP) 

The PHP is a three-week, fifteen-session program, including group therapy sessions four and a half hours per day, Monday through Friday from 8:00am to 12:30pm.

Group therapy offered in the program focuses on stabilization and learning coping skills for managing chronic and persistent mental illness. A nurse practitioner and attending physician provide medication management.

Adult intensive outpatient program (IOP)

The IOP is a six-week, twenty four-session program that includes group therapy sessions three hours per day, Monday through Thursday from 1:00pm to 4:00pm.

The IOP provides assistance through two different tracks focusing on mental health, co-occurring substance use and medication assisted treatment.

Adult evening intensive outpatient program

The evening IOP is a six- week, twenty four-session program focusing on mental health that includes group therapy sessions three hours per day, Monday through Thursday from 4:30pm to 7:30pm.
