ABSTRACT

Psychological inflexibility is maintained by experiential avoidance, cognitive fusion, attachment to the conceptualised self. The Hexaflex can also be clustered into component parts. On the left side can be brought together to broadly describe mindfulness processes. The right side of the Hexaflex then brings together the values-based behavioural activation process. The second way the Hexaflex can be clustered is into the processes of Open, Aware and Active. The Hexaflex is a powerful tool to help describe and understand the key processes and is useful for providing an overview for some of the key sources of stuckness. At the heart of the acceptance & commitment therapy model lies psychological flexibility. Psychological flexibility comprises six sub-processes, namely acceptance, defusion, contact with the present moment, self-as-context, values, and committed action. These six processes are set out visually in a hexagon, known colloquially as the Hexaflex.
