The least restrictive interventions should always be used when dealing with incidents of challenging behaviour. This is because restrictive interventions are invasive to an individual and deprive them of their basic liberties, which is unlawful except in exceptional circumstances.It may also be intimidating and frightening to them especially if they are in a confused state and could escalate the situation further. In addition, it may be necessary to justify any actions taken at a later date. Finally, thinking in terms of the least restrictive intervention creates a good mindset for any challenging behaviour you have to manage in the future.
