简要总结
Symptoms of schizophrenia have historically been treatment resistant despite advances in psychopharmacology. Acceptance and Commitment Therapy (ACT) has been shown through some preliminary research to be effective with psychotic symptoms (Bach & Hayes, 2002). ACT is considered part of the "third wave of CBT" along with Dialectical Behavior Therapy (DBT; Linehan, 1993) and Mindfulness-based Cognitive Therapy (MBCT; Segal, Williams, & Teasdale, 2001). The target of change in ACT is acceptance of symptoms as experiences that a person can have without experiencing distress, and while living a life in accordance with one's values.
The current study assessed the effectiveness of ACT (8 sessions) for delusions. Participants received treatment as usual throughout the study. The intervention followed the protocol of ACT described in Hayes, Strosahl and Wilson (1999) in which treatment will consist of building acceptance, willingness, and commitment to change, clarifying values, defusion of thoughts and feelings, as well as defusion of self. These therapeutic aims attempted to be achieved by the practice of various exercises in and out of session as well as the discussion of various metaphors within session. It was hypothesized that participants will exhibit decreased distress due to delusions, decreased delusional conviction and a reduction of overall anxiety levels from participants' baselines.
详细描述
Four patients were recruited from New York Presbyterian Hospital, Weill Medical College, Payne Whitney Clinic (Manhattan Campus), outpatient psychiatric program. Patients were randomly assigned to a length of baseline before beginning the 8-week ACT treatment. There was be a five-week baseline period for all patients after which two patients will be introduced to ACT treatment in weekly increments. All patients received treatment as usual throughout baseline and ACT treatment. During baseline, patients were assessed by an independent rater every week and during ACT treatment, patients were assessed every other week and at a one-month follow-up. Each participant's assessment results were compared over time, so that there will be an established baseline level of functioning which will be compared to his or her level of functioning during treatment, at the end of treatment, and finally at the one-month follow-up. Hypotheses: It was hypothesized that patients' distress, anxiety and tension due to delusional thinking would decrease over time when comparing baseline to treatment, treatment to outcome, and then outcome to follow-up. Additionally, the number of delusional thoughts and the rate of re-hospitalization was hypothesized to decrease over time.
