What are the key concepts of behavioural therapy?

Behavioural therapy is grounded in the belief that all behaviour is learned and can be changed through structured support. Some key concepts include reinforcement, which strengthens desired behaviours by rewarding them; modelling, where children learn by observing others; and shaping, where complex behaviours are taught in small, achievable steps. Another key principle is functional behaviour analysis, which helps identify the reasons behind challenging behaviours so that therapists can teach more appropriate alternatives. Behavioural therapy also relies on data-driven decision making—collecting and analysing behaviour patterns to ensure that interventions are working. Under NDIS, these concepts are implemented through Positive Behaviour Support (PBS) plans that prioritise the child's dignity, reduce restrictive practices, and promote meaningful participation in everyday life.
