2018 Annual Report

2018 Annual Report

As President of ACBS, I am delighted to share an update on our activities and successes over the last year, and more importantly, the initiatives we are planning for the future. 

Looking back

There is much to celebrate and be proud of in 2018. ACBS is a remarkable organisation and our annual report is a show stopper. Here are some highlights: 

  • We are a community. We have almost 8,000 members worldwide who contribute values-based dues. We also have committees, special interest groups, and the elected board, all working as committed volunteers with passion and vision of advancing science and practice. 
  • The World Conference was in Montréal, Canada in July. It was attended by 926 people. We had a fabulous line up of international speakers, members of ACBS, and guest speakers. Best of all was the vibe as the members came together to share their vision. Did you know many key talks at our conferences are recorded? See the videos here.  
  • Our journal, JCBS, is alive and thriving. For the first time, we now have an  impact factor of 1.216. Did you know ACBS members get to read the journal for free
  • The community is vibrant with nearly 2,000 people joining in discussion on our professional listserv. Join the listservs here

Looking to the future

2019 is set to be a year of expanding our vision and opening up new opportunities. 

  • In February, the ACBS Board spent a weekend planning the 3-year strategy to galvanize our organisation and help our community thrive. Over the past few months facilitators have worked to gather the views of members and the board, working hard to turn that into strategy to guide our action. Stay tuned. 
  • In June, we'll have the World Conference in Dublin, Ireland! We all know the Irish are legendary in their hosting of events, so this isn't the conference you want to miss. 
  • ACBS Voices will be a new podcast that will share the tales and tall stories of ACBS' committee, SIG, and board activities. Episodes not to be missed. Details soon...
  • Register for new opportunities. We will be calling for applications for talented people to fill a few vacancies on our committees soon. Working on our committees is a wonderful learning and growth opportunity. Please consider getting personally and professionally involved with the mission of ACBS. Join the gang and get involved here

The organisation is growing in many ways, and you can look forward to learning more about the services we are providing throughout the year!

Warmly,

2020 Annual Report

2020 Annual Report

At the close of perhaps the most impactful year many of us have ever known, I am writing to you from just south of Boston, listening in the darkness to the sounds of the ocean. The stars are bright and clear tonight, with Orion the hunter, followed by Sirius, the bright blue dog star, overhead. It is cold; the grass is brittle with ice. The windows glow with warmth behind me. I have been honored to work as the President of the Board this year. I am blessed with committed colleagues who love ACBS, who put in many hours weekly to support it, to help us as an organization grow in our wisdom and support of our members, to reflect honestly about where we can grow. I am lucky. Not all of us are so lucky.

ACBS is growing. We are growing steadily more diverse, with members around the world, from many cultures and nations, from different professions from coaches to public health scientists to evolutionary biologists, from marginalized to privileged groups. It is exciting to me that our organization may become a scientific home for so many different perspectives, for as we become more varied, and as we flex our thinking, we will richen and deepen our work.

But we are also experiencing growing pains. We continue to grapple with how best to amplify the diverse perspectives that make up our community; we continue to build our infrastructure to support our scientific and clinical goals; and we have had to be flexible to find our way through 2020. It has been a challenging year around the world. Yet, true to our nature, our community has stepped up, has reached out, has marshalled our resources to support those around us as we make our way through the COVID-19 pandemic. Many in ACBS have been creating resources, offering their time pro-bono, and reaching out in support of our colleagues and communities. If you are one of our members who has done this, thank you. Thank you for representing us well, and thank you for your generosity, time, and for sharing your expertise.

Now at the beginning of 2021, as the year turns towards the light and begins the slow and quiet shift into a new season, it seems a good time to reflect on how this time has changed us and has forged our community into something new.

Little did we know.

Little did we know that 2020 would be a year that would bring fires and floods around the world, the steady loss of biodiversity, unrest in many countries, and to top it off, we are in the middle of a pandemic that has resulted in mass lockdowns and over 2 million deaths.

Little did we know how short our time would be with each other. We have suffered many losses in our families, in our friends, to COVID. 

Let’s pause for a moment and breathe. A good friend of mine sometimes reminds me that we can only take steps from where we are – not from where we wish to be. So let us take some steps now, as we are, together. And let us look back to see how far we have come.

2021 Annual Report

2021 Annual Report

With 2021 behind us, we continue to wrestle with the reality of a global pandemic and the myriad challenges it has presented. Many -- if not all of us -- have had pain and loss. These trying times have required us to adapt and to grow in ways that we might not have anticipated under ordinary circumstances. Now more than ever, ACBS is striving to evolve in such a way that we might be an organization worthy of our members, ready to meet the challenges of the coming year.

And we have indeed evolved - ACBS is now a community of 9,200 people representing over 100 countries. For the second year running, we held our annual World Conference online with record attendance: 1500 attendees from 69 counties. Our hope was to make this conference the most accessible to date by including offerings in both Spanish and Portuguese and by offering reduced rates for members from low and middle income countries (LAMIC). In addition, ACBS created a number of new resources for our members, including video recordings of the 2020 World Conference, many of which are available in Spanish.

Also of note this year, several ACBS chapters - India, Poland and Türkiye - hosted conferences that were culturally tailored and designed to be accessible to members of LAMIC and other communities. Our Awards committee created a new award intended to support work that advances diversity, equity and inclusion in our community. The strategic teams that are entrusted with carrying out the work of our four pillar plan have made commendable progress, including three major projects and several upcoming papers. Finally, the impact factor of the Journal of Contextual Behavioral Science (JCBS) more than doubled, going from 1.523 to 3.092 in just one year.

Looking forward, we hope to make 2022 a year of connection -- expanding our work and creating new opportunities for our members. In June of 2022, we will host our World Conference in San Francisco, California. At this writing, we are working to make at least some offerings available online as we move toward an increasingly hybrid model for our annual conferences. We will also be calling for applications for talented people to fill a few vacancies on our committees and to work with our strategic pillar teams. We are always looking for passionate people who want to help shape the future of ACBS. Please consider getting personally and professionally involved with our mission. You can explore opportunities here.

2024 Letter from the Board President

 

“Never doubt that a small group of thoughtful, committed citizens can change the world, indeed, it's the only thing that ever has” - Margaret Mead

We are a diverse group of over 8100 people united in a common purpose. Our impact is amplified by our unique voices and our collective action. What will we do, what will you do, this year that will make a difference? Even the smallest actions reverberate.

To know where we are going, we need to know where we have been. We have a lot to be excited about.

This year…

  • We held our very first World Conference in South America. In-person attendance was incredible, and we launched a virtual encore to reach individuals for whom travel was a barrier.
  • The Scientific Strategy Committee was established as a more permanent outgrowth of the Centering Science Pillar, spearheading initiatives that will increase member access to CBS research methodology and broaden CBS collaborations.
  • We chose another outstanding JCBS Editor, Dr. Sahdra Baljinder, who has continued the great work of previous Editors, and increased diversity of the Editorial Board and visibility of JCBS publications.
  • We made progress in determining how to measure competency in CBS in clinical and training contexts with members of the Competency Pillar at the helm.
  • JEDI initiatives continued to advance under the leadership of the DEI committee.
  • We came together to share our science on CBS SuperLab and worked with Chapter leadership to solve problems and build stronger Chapters.
  • We launched a new website, established new SIGs in areas such as neurodiversity affirming research and practice, and values and meaning making and a new Chapter in Chile.
  • We welcomed our first peer-reviewed trainer in Turkiye and 6 new ACBS fellows.
  • We awarded 25 scholarships that increased access and participation in CBS, and 4 grants for CBS-related research.

This is significant, and I can’t wait to see what we will do next. Please consider taking an active role in ACBS. We can do more together than we can alone. You can indicate your interest in leadership or service in ACBS here.

Looking forward to building community with you,

2025 Annual Report

2025 Annual Report
Read Manuela's Letter

Dear Members of the Association for Contextual Behavioral Science (ACBS),

As I reflect on this past year, I am filled with deep appreciation for the vitality, generosity, and shared commitment that continue to shape ACBS. Our association is more than an organization—it is a living community of practice, inquiry, and care, held together by a shared dedication to alleviating human suffering and promoting psychological flexibility across contexts and cultures.

This year has been one of growth, learning, and meaningful connection. Across regions and disciplines, ACBS members have advanced research, strengthened clinical practice, expanded training opportunities, and fostered spaces of inclusion and collaboration. Our chapters, SIGs, committees, and volunteers have once again shown that ACBS thrives because of the willingness of its members to contribute time, creativity, and heart.

At the same time, we have continued to ask important questions about who we are and who we aspire to be as a global community. This year marked the debut of the Global CBS Exchange, a fully virtual, around-the-clock training and research event, designed to increase accessibility and strengthen global engagement. By offering high-quality learning opportunities across time zones, we took a meaningful step toward bringing contextual behavioral science education to more people, wherever they are. 

These efforts reflect our shared understanding that science and practice are always embedded in relationships, cultures, and lived experience.

October brought a joyful celebration of our 20th anniversary. As we look back on how far we have come—and ahead to where we are going—we can clearly see the remarkable growth that has unfolded over these years, and with our Strategic Plan, we are committed to nurturing that growth into the future.

After years of collaborative work across the Competency Pillar, the Training Community, and dedicated Board members, ACBS released its first International Standards of Training and Supervision in Psychological Therapies based on CBS. These standards represent a major milestone, offering a shared framework to guide training, research, and practice worldwide, while remaining aligned with our core value of an open, non-hierarchical community. I personally appreciate this initiative, as it serves as a clear and compassionate lighthouse to guide the dissemination of Contextual Behavioral Science.

Another deeply meaningful initiative this year, led by staff, to increase global access of our digital resources included adding translations in 12 languages to many of the videos available on the ACBS website. . This effort touches me profoundly, as it directly addresses language barriers and significantly advances equity and access for diverse linguistic communities around the world.

I want to express my sincere gratitude to the Board of Directors, committee members, staff, chapter leaders, trainers, researchers, and all those who serve ACBS in visible and invisible ways. Your dedication sustains the integrity, warmth, and continuity of this community. I am also deeply grateful to our members—your curiosity, courage, and engagement are the foundation of everything we do. We all are ACBS.

As you read this annual report, I invite you to see it not only as a summary of accomplishments, but as a reflection of a collective journey. ACBS continues to evolve because we walk this path together—grounded in values, guided by science, and animated by care.

Thank you for being part of this community and for contributing to the ongoing unfolding of contextual behavioral science.

With appreciation and commitment,

Manuela O’Connell
President, Association for Contextual Behavioral Science

Journal of Contextual Behavioral Science (JCBS)

In 2025, JCBS continued to strengthen its reputation as a leading scientific platform for contextual behavioral research. The journal successfully launched two special issues, advanced a mentorship program supporting emerging scholars (now entering its concluding phase), and maintained strong efficiency in manuscript processing through the efforts of a highly engaged editorial board.

JCBS remains a central outlet for rigorous, applied, and globally relevant CBS.

2025 ACBS World Conference

The 2025 ACBS World Conference continued to serve as a flagship gathering point for contextual behavioral scientists, clinicians, students, and practitioners from across the globe. Participants engaged in a diverse range of sessions highlighting cutting-edge science, clinical innovation, dissemination efforts, and applied CBS practices.

2025 World Conference by the Numbers:

  • 800 total attendees
  • 37 countries represented
  • 250 pre-conference workshop attendees (in person)
  • 128 pre-conference workshop attendees (virtual)
  • 155 total sessions
  • 68 poster presenters
  • 20 scholarships awarded
  • 12 awards presented

These numbers reflect the continued growth and accessibility of the conference, including hybrid workshop participation and sustained financial support for scholars and practitioners.

Global CBS Exchange

Attendees: 221
Countries represented: 39

The Global CBS Exchange continued to serve as a powerful platform for cross-cultural learning, collaboration, and shared growth within the CBS community.

Financials

Keeping ACBS thriving takes meaningful resources—from staffing and technology to global programming, scientific initiatives, and community support structures. Member dues play a critical role in sustaining this work. 

The Power of Values-Based Dues

ACBS operates on a values-based dues model, which allows members to contribute at levels aligned with their financial ability and commitment to the community.

When members are able to give more, it directly expands access for others.

Higher contributions enable ACBS to:

  • Support more scholarships and awards
  • Make events more affordable and inclusive
  • Expand global impact by providing resources, training, and—when possible—membership access to under-resourced communities.

Looking Ahead

In 2025, ACBS strengthened its foundation while expanding its global reach. Through grants, conferences, publications, training, and volunteer leadership, ACBS continues to advance contextual behavioral science in ways that are inclusive, innovative, and deeply connected to real-world impact.

Together, we are building a vibrant, creative, and collaborative CBS community—one year at a time.
