environments that services or others create around people with developmental disabilities, and a method of communicating dissatisfaction with the failure of services or others to listen for what kind of life makes most sense to the person, especially where services or others create lifestyles and relationships that are centred on what suits them or the service and its staff rather than what suits the person. Challenging behaviour can often be viewed as a ‘behavioural equivalent’ of a mental health problem. However, research evidence indicates that challenging behaviours and mental health problems are relatively independent conditions. A common principle in behaviour management is looking for the message an individual is communicating through their challenging behaviour: "All behaviour has meaning". This is a core in the functional analysis process. Children communicate through their behaviour, especially those who have not acquired language and vocabulary skills to tell the adult what the problem is. In adults with developmental disabilities certain types of challenging behaviour can predict contact with police and hospital admission. Behaviour response cycle Challenging behaviours may be viewed as occurring in a cycle: Trigger Escalation Crisis Recovery Analysis of this cycle provides a foundation for using a variety of strategies to minimise the triggers of challenging behaviour, teach more appropriate behaviours in response to these triggers, or provide consequences to the challenging behaviour that will encourage a more appropriate response. Behavioural strategies such as Applied Behaviour Analysis, operant conditioning and positive behaviour support use similar approaches to analysing and responding to challenging behaviours. Recently, Eidetic Model of Growth (EMG) has been used with promising results.
