The Australia and New Zealand Chapter of the
Association for Contextual Behavioral Science (ANZ ACBS)

Who We Are

ANZ ACBS is a registered health promotion charity dedicated to alleviation of human suffering and advancement of human well-being through research and practice grounded in contextual behavioural science.


ANZ ACBS was founded in 2009 and is a community for researchers, educators and practitioners promoting and advancing contextual behavioural science. It is the home of Acceptance and Commitment Therapy (ACT), Relational Frame Theory (RFT) and Functional Analytic Psychotherapy (FAP) in our region.

What We Do

As a chapter of the worldwide Association for Contextual Behavioral Science, ANZ ACBS works to spread contextual behavioural science (CBS) through our region by

  • creating opportunities for members to connect and share research, resources, and practice experience

  • hosting high quality professional development events attracting local and international researchers and trainers

  • working to promote inclusion of contextual behavioural science to the curriculum of psychology, education, medicine, social work, and allied health


Our conferences and training events typically have a strong focus on ACT, RFT, FAP and the emerging field of process-based therapies. Therapeutic approaches including Compassion-Focused Therapy (CFT) and Dialectical Behaviour Therapy (DBT) are also frequently featured because of similarity and compatibility with CBS approaches.

Our Guiding Principles and Values

The popular ACBS phrase of “living and leading with our head, heart and hands,” was introduced by Steve Hayes, one of the Acceptance and Commitment Therapy founders, as a model for promoting vital lives and communities. So, what does this phrase mean specifically for us at ANZ ACBS?

The Head. Our Science: What We Do.


The head (or foundation) of our work at ANZ ACBS is cultivated at the intersection of basic science, applied science, and practice. The head is what we do (i.e., promote local CBS research and scholarship, organise our regional conference and practical workshops, etc.) in the service of the heart (the why).

The Heart. Our Purpose: Why We Do it.


The heart is the compass that directs what we do and how we do it. The ANZ ACBS heart is focused on researching, teaching and disseminating powerful, empirically supported, accessible and compassionate ways of alleviating human suffering and connecting people to vitality.

The Hands. Our Community and Values: How We Do It.


Stepping up and committing to our organisation’s values requires the cultivation, nourishment and cooperation of a local and global CBS community - the hands. Our community is made up of local board members and staff, local members across Australia and New Zealand, and international ACBS members. Social change is consciously built into our organisation. As a community, ANZ ACBS is committed to values of accessibility, transparency, pragmatism (doing what works), generous scholarship and practice, and philanthropy.

Lisa Mastin-Purcell

Acting Secretary

​Lisa is a Master of Clinical Psychology candidate and part of the CBS ACTUALISE Lab at La Trobe University. Before studying psychology, Lisa spent 5 years working in corporate Learning and Development – she loved helping people to learn but something was missing. She wanted to help people to live more meaningful lives, to find the things they were passionate about, the things that really matter to them. Lisa first came across ACT in her undergraduate years and it resonated with her immediately. She then had the opportunity in 2019 to undertake her honours thesis under the supervision of Eric Morris looking at the role of Psychological Flexibility in sleep and that’s where her ACT journey really began. Since then she has become interested in both the research and applied sides of ACT, Psychological Flexibility and CBS. In 2020, Lisa began her postgraduate psychology studies, where she looks forward to learning more about the clinical side of ACT and undertaking research into psychological flexibility.

She has a Bachelor of Psychology and Graduate Diploma in Education (School Psychology).

Renae believes every person has the ability to make meaningful and value-centred decisions about their lives. Therefore, working in partnership with children, young people and families is central to her approach. Reneae views the role of a psychologist as not to be an expert about a person’s life as that is their role, but to bring their understanding of psychology, development, mental health and wellbeing, to shine a light on certain areas the person or family are raising, and to support them to build their own understanding and to live a meaningful life, whatever that looks like to them.


Brendon Knott


Brendon is a clinical psychologist who first discovered ACT and CBS in 2002 and found that functional contextualism was an ideal framework for working with compassion, flexibility and precision, with divserse populations in both a public community health setting, along with private practice. Brendon is also a lecturer and trainer who is passionate about helping students and clinicians who wish to deepen their understanding of ACT and contextual behavioural therapies, and to ground their clinical work in the foundational building blocks of functional contextualism, behaviour-analytic principles, and relational frame theory. He has lectured undergraduate and post-graduate psychology students in ACT and CBS for over 10 years at the University of Newcastle, provides CBS-related videos on his YouTube channel (Contextual Interventions), and in recent years has run training workshops at national and international conferences. Brendon has a deep interest in the broader applications of CBS skills, and works as a research consultant on a number of projects in this area. He has co-developed a mobile phone app for medical students which delivers ACT skills training in a format tailored to the individual, and a set of virtual reality training modules for the Australian Defence Force (Performance Edge) which delivers CBS-related skills in an immersive training format.

Vin Allen

NZ Representative

Vin is a PhD student at the University of Auckland in the department of Psychological Medicine. He and his team are currently working on a project to develop digital tools to support the delivery of Focused Acceptance and Commitment Therapy (fACT) in New Zealand primary care contexts. He's a big fan of third-wave behavioural therapies such as ACT and fACT, and extending the use of these to solve population health problems is a primary focus of the team's research. Mental health research is one of Vin's passions, and he feels very lucky to be able to make a living out of doing research in this area. He's always been passionate about the philosophy of Behaviourism, and credit's B. F. Skinner’s Radical Behaviourism for initially sparked his interest in Relational Frame Theory, and subsequently Contextual Behavioural Sciences. These approaches underlie all of his research endeavours, and he's keen to be a part of a community of fellow CBS researchers.


Andrew St Lawrence

Student Representative

Andrew is a Master of Clinical Psychology candidate at La Trobe University. Before studying psychology, Andrew spent time working as an Automotive Engineer in Detroit, Michigan, and although springs and gears are undoubtedly fascinating, in 2017 Andrew decided to shift his career toward his passion of helping people do more of what matters to them. Alongside his formal psychological training, Andrew spent time in Mental Health Support in Complex Services, where he started an educational initiative for other mental health professionals to learn about ACT-based concepts. Andrew favours ACT as his primary therapeutic approach in his clinical role as a Provisional Psychologist, and relishes opportunities to learn more about contextual behavioural science through his studies. Currently completing his Master’s thesis under the supervision of Eric Morris, Andrew is investigating the role of self-transcendence and other psychological flexibility processes in mitigating paranoia symptomology. Andrew is now completing the final year of his postgraduate training, and looks forward to learning more about CBS in other clinical settings.
