Last updated: October 2024

The intent of this list is to add all randomized controlled trials of Acceptance and Commitment Therapy and its components that have appeared in the scientific literature, whether alone or in combination with other methods, under the label "ACT" or the closely related terms such as "Acceptance-based behavior therapy" or "mindfulness-acceptance-commitment" and so on, regardless of outcome, language, or country of origin. Only articles appearing in a scientific journal will be included in the list. Dissertations, theses, working papers, conference presentations, studies in book chapters, and so on are not listed until they appear in a scientific journal. 

The following information will be provided about each study:

Trial area (main target and population; e.g., Social Anxiety). Trial conditions (e.g., ACT vs. wait list). Total number of participants (e.g., N=48).
APA reference.
DOI (digital object identifier) if available and/or link to full text of study if available.

The explosion of ACT research in the non-English speaking world over the last several years presents a challenge to indexing, especially in languages that are not fully indexed in Web of Science and similar outlets. At times there is an English abstract but it may lack needed details, or there is no English abstract at all. It has seemed best in those conditions simply to state in this list what can be gleaned from what is available. Beginning in Fall 2024 however we have been uploading non-English pdfs into Large Language Models. We are curating the LLMs to generate the information above for this list. The results are impressive so far, thus if readers need additional information, we encourage readers to consult the full article and have a trustworthy LLN translate it. The researcher can also be contacted of course. 

Some of the world's literature is in very obscure journals. Due to the difficulty in locating these studies we are constantly updating this list and in the interests of efficiency we are no longer numbering individual studies. The yearly total and overall total are still listed, however. Occasionally an RCT is published in waves with different outcomes in specific articles. We include some of these below, but we only count an RCT once in the yearly and overall totals. That means you will see more entries on the list than are in the summary numbers. We've tried to find all the RCTs and to list the main outcomes paper, and we are pretty sure we've not counted any twice, but we've not put effort into finding every article published on a given RCT data set so you will have to use the usual search processes (e.g., looking at the studies that cited the main outcomes paper) to do that.

You can search for relevant studies on this list by entering a search term in your browser while looked at this page. The way to do that varies by type of computer and browser (e.g., on a Mac it's usually command-F). Do not enter a search term in the search box on this page - that will search the entire ACBS website.

If you are using this list to determine to what degree ACT is evidence-based in a particular area, please do not just count studies. Read them carefully, contact the authors, and consider their strengths and weaknesses. Every study, no matter how obscure, hard to find, or small, can add incrementally to our knowledge. You will see several hundred studies here from LMIC countries, and often questions are asked in an LMIC context that would never even occur to those in major Western academic medical centers studying WEIRD (Western, educated, industrialized, rich, and democratic) populations only. Only about 11% of the world's population resides in WEIRD or higher income countries even though over 80% of the world's scientific literature comes from there (in psychology some estimates put that domination in the 90s!) and the citations of the world's literature can be that distorted or worse. The entire world benefits when all of us have a voice, and we've worked hard to find every study in part for that reason. If you want to consider whether ACT is evidence based in a given area, look at the meta-analyses and the systematic, scoping, or narrative reviews (go to bit.ly/ACTmetas), and consult the reviews of respected agencies (the World Health Organization; the NICE guidelines; the CDC; NREPP and so on), or do your own systematic review. You should also examine ACT failures (you can find a list here: https://contextualscience.org/negative_findings) and the moderators that suggest that other methods may be more helpful in some contexts. Consider processes of change, and more intensive idiographic studies, not just RCTs. Some of the other daughter pages of the "State of the Evidence" page (this very page is a daughter page of that main page) will help. The Task Force Report on the Strategies and Tactics of CBS Research will explain why these other kinds of studies are increasingly important to the CBS research agenda (the Task Force report is published in JCBS and is open access -- it is attached to this page for free downloading). Yes, the volume and breadth of randomized trials is worth noting, but mindlessly counting up RCTs is not the way to make good scientific or clinical decisions.

Note there are now studies of the content focus of the first 1,000 trials from this list: Hayes, S. C. & King, G. (2024). Acceptance and Commitment Therapy: What the history of ACT and the first 1,000 randomized controlled trials reveal. Journal of Contextual Behavioral Science, 33, 100809.

If you've found an ACT RCT that is not on this list, please send a note to missing dot studies @ gmail.com. (the word "dot" is a period and take out spaces -- listing the address this way avoids spam). If it is at all possible, please attach a pdf of the study itself, and in the text of your email list the reference and all authors in an APA style reference, provide the DOI number, and suggest a header that lists the trial area (problem and population), conditions, and total number of participants, using the way studies are presented here as a guide. At the bottom of the page there are PowerPoint slides on these data and an Excel spreadsheet and Word document with the references -- if you are signed in as a member you can see them and you are free to download and use them.

Three-fourths were above clinical cutoffs in general mental health, depression, anxiety, or stress. Participants read the book for two months, completed exercises and quizzes, and after post assessment were followed for 10 weeks; wait list participants were then also given the book with two months to complete it. Overall, participants showed significant improvement in psychological health. Significant preventive effects for depression and anxiety were observed along with significant ameliorative effects for those in the clinical ranges of depression, anxiety and stress. Follow up general mental health, depression, and anxiety outcomes were related to the manner in which participants used the workbook and to post levels of psychological flexibility.

Values are not just goals: Online ACT-based values training adds to goal setting in improving undergraduate college student performance. Journal of Contextual Behavioral Science, 2, 79-84.  RCT (N = 132) comparing wait list, goal setting, or goal setting plus ACT values work with college students. Higher GPA at post in the values plus goal setting condition over next semester. After one semester, the wait list was then given values plus goal setting and the same effect was seen, over the next semester.

Open trial (N=41) self-referred women with a fibromyalgia diagnosis, pre/post/ 6 mo f-up. The 10-week Internet-delivered ACT + contact with an online ACT therapist. Moderate to large within-group effect sizes on all main measures (d = 0.62-1.56; symptoms and impact, disability, quality of life, depression, anxiety, fatigue, and psychological flexibility.) Improvements maintained at follow-up. Positive cost-benefit by 2 mos.

Journal of Clinical Oncology, 31, 2313-2321. DOI: 10.1200/JCO.2012.45.5873   Large RCT (N = 410) with colorectal cancer survivors assigned to usual care or to 11 ACT-based telephone health coaching sessions over 6 months focusing for physical activity, weight management, dietary habits, alcohol, and smoking. Significant differences at 1 year follow up for physical activity, body mass, and fat intake; vegetable intake better at 6 month. Alcohol and smoking not significantly different.

Nicotine & Tobacco Research, 15(10), 1756-1764. DOI: 10.1093/ntr/ntt056  RCT (N = 222) of a web-based ACT intervention for smoking cessation as compared to the U. S. National Cancer Institute’s Smokefree.gov website. Participants spent significantly longer on the ACT site and we more satisfied with it; quite rates at 3 month follow up were more than double on the ACT site than the NCI site (23% vs. 10%). Smoking cessation was mediated by increases in total acceptance of physical, cognitive, and emotional cues to smoke (80% of the effect).

Given that therapy can only be effective when clients are attending sessions and are actively engaging with the treatment, it is crucial to determine ways to increase adherence and reduce attrition. The following is a list of studies that determine the effectiveness of ACT in reducing drop out and/or increasing adherence or engagement in treatment (list gathered by Brandon Gaudiano).

Links to peer reviewed assessments of the ACT evidence base:

Below is a list of meta-analyses, systematic, scoping, or narrative reviews of the ACT evidence base, either overall or in specific areas. These can include reviews of assesment, psychological flexibility processes, ACT components, or entire ACT interventions. Also there are a few reviews in there that are focused on the process or professional use of ACT research such as bibliometric, geographic, sociological, methodolgical, citation, and similar reviews. They are presented in reverse chronological order, by year of publication.  To see the growth trend through the end of 2022 visually click here or download the attachment at the bottom of this page.  High quality reviews and meta-analyses are increasingly necessary in order to understand and evaluate the ACT database given its size and scope, and are to be preferred over crude counts of studies, single citations, or other more limited means. Note by way of caution that many meta-analyses cover various parts of evidence based therapy in addition to ACT (e.g., "mindfulness-based interventions" or "CBT including 3rd wave interventions" etc) and when combined with specific problem targets this does mean that some reviews in this list only include 1 or 2 ACT studies, but it sseems better to be comprehensive so these are also included. We do not filter studies based on that they find or what they say about ACT, good, bad, or indifferent. You should be aware, however, that it is very difficult to evaluate the quality and fairness of meta-analyses themselves. A few well known meta-analyses have turned out to contain many errors when examined closely (e.g., see Atkins et al., 2017). In that context it is worth noting that meta-analyses of meta-analyses -- a kind of a super summary -- are now beginning to appear (e.g., Cheng et al., 2022; Gloster et al., 2020). This is a recent development but hopefully these can detect or at least balance out various sources of bias. The ACT community is committed to honesty and transparency and has a long history of welcoming criticism such as by inviting critics to ACBS conferences and giving them an open platform to express their concerns. If you have criticisms of the ACT research literature, we would enourage you to consider outlets such as JCBS or generating a session at the next ACBS World Conference. If you are aware of any missing reviews, please send them to missingstudies at gmail dot com.
