Abstract
'Treatment' connotes 'one off' and 'short-term' and treatments are applied after problems have failed to respond to natural, culturally acceptable methods. In developmental disability, continuing interventions that begin early are our best hope; natural methods are part of the problem. Treatment methods are validated for particular problems and circumstances, need to be applied competently and monitored by therapists who have throrough grounding in scientific method and principles of behaviour. Nominating empirically validated treatments does not diminish the need for highly trained behaviour analysts.
