Course Outline

Programme aims and objectives:

  • To provide professional post-graduate training in behavioural psychology which will prepare students to provide effective services in a professional and ethical manner.
  • To teach specialist knowledge in behavioural psychology, from history and basic concepts to specific behavioural assessment and intervention strategies.
  • To train students as scientist-practitioners, competent in applied research methods and whose practice is guided by scientific knowledge and the scientific underpinnings of their practice.
  • To equip students with competencies to practice effectively, competent in behavioural assessment and intervention strategies, data-based decision-making, and behaviour change systems.
  • To equip students with the skills required to work successfully within both autonomous and collaborative roles, and with professionals from other disciplines.
  • To train students to appraise the quality of scientific evidence and apply this understanding and critical thinking within both research and practice.
  • To teach students to conduct high quality empirical behavioural psychology research.

Philosophy and Orientation of the Programme

Within psychology, the field of behavioural psychology or behaviour analysis focuses on the application of the principles of behaviour and learning to support success, alleviate behavioural difficulties, and enhance quality of life across a variety of contexts. The MSc in ABA programme instils in trainees the values and skills necessary to do so. Core values outlined by Baer, Wolf, and Risley (1968; 1987) in defining the field of applied behaviour analysis are upheld.

The central foundation of this programme is the scientist-practitioner model, the concept and application of which is weaved through academic content and supervised experience. Trainees learn about the core principles of behaviour, the science of behaviour, experimentation and evidence-based practice, as well as attain competence in the implementation and evaluation of specific assessment methods and intervention strategies. Reliance on evidence and scientific knowledge is a core value of the programme.

Also a core value emphasised throughout the programme, is the provision of only those services which are socially significant to each individual that we work alongside. The selection of goals and assessment and intervention strategies must be in accordance with our charge as a field to only provide services that are ethical, contextually appropriate, have high acceptability, represent the least-intrusive approach, and are worthwhile for each individual. Students will graduate from this programme with extensive knowledge and experience of ethical and appropriate professional.

What Graduates Say


Shauna Diffley |   Graduate

I completed my MSc in Applied Behaviour Analysis between 2019-2021. Over the two years, I developed the skill set of a practitioner and researcher alike. The course provided expert training in instructional design, behavioural assessment, developmental disorders, organisational behavioural management, and clinical behavioural interventions, to name but a few components. I found the affiliated course placement very useful, as it allowed me to put the theory I had learned into practice under expert supervision. The lecturers on the course are so approachable and are expert practitioners and researchers in the field. As a result of the Covid-19 pandemic, our course moved online in semester 2 of year one. The situation was handled impeccably by the teaching staff, and they were so supportive and reassuring during a really difficult time and ensured that the pandemic did not impact our learning experience. I enjoyed the course so much that I decided I wasn’t ready to leave, and I am currently pursuing the Structured PhD in Applied Behaviour Analysis here at NUI Galway, for which the MSc in Applied Behaviour Analysis has prepared me perfectly.
