    RCT showing that ACT + patient education is significantly better than patient education alone in producing good self-management and better blood glucose levels in lower SES patients with Type II diabetes. Effects at follow up are mediated by changes in self-management and greater psychological flexibility with regard to diabetes related thoughts and feelings.

Results indicate that only the ACT intervention was effective in increasing positive behavioral intentions at post and a 1-week follow-up. These changes were associated with other self-reported changes that fit with the ACT model.

    108 chronic pain patients with a long history of treatment are followed through an ACT-based 3-4 week residential treatment program. Measures improved from initial assessment to pre-treatment on average only 3% (average of 3.9 month wait), but improved on average 34% following treatment. 81% of these gains were retained through a 3 month follow up. Changes in acceptance predicted positive changes in depression, pain related anxiety, physical disability, psychosocial disability, and the ability to stand. Positive outcomes were also seen in a timed walk, decreased medical visits, daily rest due to pain, pain intensity, and decreased pain medication use.

    Medium sized randomized controlled trial comparing ACT to nicotine replacement therapy (NRT) as a method of smoking cessation. Quit rates were similar at post but at a one-year follow-up the two groups differed significantly. The ACT group had maintained their gains (35% quit rates) while the NRT quit rates had fallen (less than 10%). Mediational analyses shows that ACT works through acceptance and response flexibility.

A randomized controlled trial of twelve-step facilitation and acceptance and commitment therapy with polysubstance abusing methadone maintained opiate addicts. Behavior Therapy, 35, 667-688.

    A large randomized controlled trial was conducted with polysubstance abusing opiate addicted individuals maintained on methadone. Participants (n=114) were randomly assigned to stay on methadone maintenance (n=38), or to add ACT (n=42), or Intensive Twelve Step Facilitation (ITSF; n=44) components. There were no differences immediately post-treatment. At the six-month follow-up participants in the ACT condition demonstrated a greater decrease in objectively measured (through monitored urinalysis) opiate use than those in the methadone maintenance condition (ITSF did not have this effect). Both the ACT and ITSF groups had lower levels of objectively measured total drug use than did methadone maintenance alone.

Development and evaluation of an integrative health model in the treatment of epilepsy: Two randomized controlled trials investigating the effects of a short term ACT intervention, yoga, and attention control therapy in India and South Africa. Unpublished thesis, University of Uppsala, Uppsala, Sweden.

    Two small RCTs (N = 18; and N = 28) comparing a three session ACT protocol (two individual; one group) to two other conditions. As compared to yoga, significantly reduced seizures in the ACT condition; as compared to attention control, significantly reduced seizures and experiential avoidance, and significantly increased quality of life in the ACT condition at a one year follow up.

    A series of controlled single case designs show that ACT, and ACT combined with habit reversal helps with hair pulling.

    Small randomized controlled trial shows that ACT is about as good as systematic desensitization in reducing math anxiety, but works according to a different process. Systematic desensitization reduced trait anxiety more. ACT results were better for high emotional avoiders. This is the only study so far with a negative effect size for ACT -- in this case in comparison to systematic desensitization.

    Shows that a three-hour ACT intervention reduces rehospitalization by 50% over a 4 month follow-up as compared to treatment as usual in the seriously mentally ill.

  • Block, J.A. & Wulfert, E. (2000). Acceptance or change: Treating socially anxious college students with ACT or CBGT. The Behavior Analyst Today, 1(2), 3-10.

    Small RCT on the treatment of social anxiety. Compared ACT to Cognitive Behavioral Group Therapy and to a no treatment control. Results indicated that ACT participants evidenced a significant increase in reported willingness to experience anxiety, a significant decrease in behavioral avoidance during public speaking, and a marginally decrease in anxiety during the exposure exercises as compared with the control group. Similar results were found for CBGT, but ACT found greater changes in behavioral avoidance.

    Randomized controlled trial. Shows that ACT is more effective than a previously empirically supported behavioral approach to reducing worksite stress and anxiety, and that both are better than a wait list control.
