  • Content Description: Acceptance and commitment therapy (ACT) was developed to specifically target experiential avoidance (EA) rather than any specific diagnostic category. A functional ACT manual was presented and used to treat diagnostically diverse clients in a large sliding fee-for-service training clinic. A multiple baseline across participants and behaviors research design was used to evaluate session-by-session changes in EA, values identification, valued action, and clinical distress. The Acceptance and Action Questionnaire-2 (AAQ2), Valued Living Questionnaire (VLQ), and Outcome Questionnaire (OQ-45) were given to measure processes and outcomes given the functional ACT model presented in the introduction to the paper. Baseline included the Structured Clinical Interview for DSM-IV Axis I and II Disorders given across 2-5 50- minute sessions. The treatment phase consisted of 7-10 50-minute sessions. Participants were 10 clients. Four participants completed sufficient treatment sessions (4-9) to test the study hypotheses. Participants generally improved across time, but most improvements could not be attributed to the functional application of ACT due to changes during baseline for AAQ, VLQ-Consistency, and OQ-45. VLQ-Importance significantly improved for all participants given ACT.
