The Psychological Services Center (PSC) was established in 1971 as a facility for training, service, and research at Oklahoma State University.  This clinic is operated by the Department of Psychology through the College of Arts and Science. The PSC is located in 118 Psychology Building on the OSU campus and also is accessible to individuals with a physical disability. 


The PSC provides services to children, adolescents, and adults. Services are available to residents of Stillwater and the surrounding community, as well as to OSU students, faculty, and staff. The PSC offers a variety of psychological services, including but not limited to: 

  • Adult and Child Individual Therapy for Adjustment Problems, Depression, Anxiety, and Post-traumatic Stress Disorder (PTSD)
  • Couples and Family Therapy
  • Assessments for Learning Disabilities, Attention-Deficit/Hyperactivity Disorder (ADHD), Emotional/Behavioral problems, and other Developmental Disabilities; the PSC Assessment Clinic does not conduct forensic evaluations, custody evaluations, and/or court-ordered evaluations.
  • Group Therapy (e.g., Meditation and Stress Reduction, Emotion Regulation, and Healthy Relationships)

Initial, required intake appointments are $10, and therapy session fees are calculated according to a sliding scale based upon level of income, with fees starting at $5 per session. Fees for assessments are also based on a sliding scale and range from $150-$1000 (OSU students pay a standard assessment fee of $250). 


The PSC's staff includes doctoral students in the clinical psychology training program. Student therapists are supervised by Clinical Psychologists in the Department of Psychology.
