Positive Behavioural Support Programmes are the treatment of choice for people displaying challenging behaviour, those with intellectual disabilities, and vulnerable others with a specific clinical need, such as Asperger’s/Autism etc. The function of the negative behaviour is analysed and positive behaviours identified that are functionally equivalent for the person. These programmes are sanction free and eliminate negative behaviour by not providing any reinforcement for these behaviours. However, natural consequences remain in place, and are explained to the person. The programme is developed and implemented together with the person’s family and/or care staff.
