ACT Guide for Decluttering

What is ACT Guide for Decluttering?

  • ACT Guide for Decluttering is an online mental health program designed by psychologists at Utah State University.
  • This program is for people who may have difficulty discarding, acquiring, or hoarding objects. You’ll learn skills to help deal with uncomfortable feelings, be more present in your life, and discover new things about yourself.

How does it work?

  • The “ACT” in ACT Guide stands for Acceptance and Commitment Therapy. It’s a way of improving your mental health and handling distress associated with discarding objects. There is growing empirical support on the efficacy of ACT for hoarding difficulties. More broadly, there have been over 1,000 randomized controlled trials showing the positive effects of using ACT for a wide range of mental health conditions (State of the ACT Evidence).
  • The ACT Research Group, led by Drs. Michael Twohig and Michael Levin, has conducted research on treating hoarding symptoms, with results showing promising outcomes and improvement for clients in ACT therapy. ACT Guide for Decluttering is designed to teach these same skills, but in a self-guided format where you can go at your own pace.
