Outpatient Veterans age 50 years and older at the West Los Angeles VA Medical Center who have chronic musculoskeletal pain complete baseline questionnaires and are randomized into one of two forms of psychotherapy: Emotional Awareness and Expression Therapy (EAET), which helps patients make connections between avoided or conflicted emotions and pain, or Cognitive Behavior Therapy (CBT), which teaches pain coping skills. Each treatment is delivered by an experienced therapist and includes one 90-minute individual session and eight 90-minute group sessions (in small groups of 8 Veterans). Patients in both conditions complete post-treatment and 3-month follow-up questionnaires. Outcomes of each type of psychotherapy are compared and mediators of treatment response are evaluated.
