Why focus on challenging behaviour?
financial cost
Need and capability in services for people with Intellectual Disabilities CAPABILITY OF SERVICE TO RESPOND INDIVIDUAL DEMAND ON SERVICE RANGE OF SERVICE PROVISION
Creating capable environments CAPABILITY OF SERVICE TO RESPOND INDIVIDUAL DEMAND ON SERVICE RANGE OF SERVICE PROVISION
Why focus on challenging behaviour?
financial cost 31% of all people with learning disabilities placed out of area (DOH 2004)
Why focus on challenging behaviour?
financial cost human cost abuse inappropriate treatment psychotropic medication restraints/protective devices degrading abusive psychological treatments exclusion, deprivation & neglect challenges the comprehensiveness of community care
Positive Behavioural Support for People with Learning Disabilities who present Challenging Behaviour
Traditional Behavioural Approaches Positive Behavioural Support • • • • • Influences Definition Characteristics Evidence Base Barriers to implementation
Early Behavioural Model
Behaviour
Early treatment strategies
Differential reinforcement schedules: reinforcement of other behaviours or low rate of behaviour.
Extinction: non-presentation of a reinforcer.
Punishment: type I application of an aversive stimulus type II removal of a positive stimulus
Punishment based strategies
Time out (Mace et al., 1986) Visual screening (Lutzker, 1978) Verbal reprimand (Schutz et al., 1978) Response satiation (Realon &Konarski, 1993) Overcorrection (Foxx & Azrin, 1973) Response interruption & manual restraint (Azrin et al., 1988) Required relaxation (Foxx & Bechtel, 1983) Mechanical restraint & protective clothing (Dorsey et al, 1982) Water mist (Dorsey et al., 1980) Aromatic ammonia (Tanner & Zeiler, 1975) Electric shock (Linscheid et al. 1990) Aversive tastes (Hogg, 1982).

Positive Behavioural Support
‘…
characterised by educational, proactive, and respectful interventions that involve teaching alternative skills to problem behaviours and changing problematic environments. It blends best practices in behavioural technology, educational methods, and ecological systems change with person-centered values in order to achieve outcomes that are meaningful to the individual and to his or her family’
Bambara et al (2004)
Positive Behavioural Support
Is values led (in that the goal of behavioural strategies is to achieve community presence, enhanced choice, improved personal competence, greater respect and community participation, rather than simply behavioural change in isolation)
Positive Behavioural Support
Is based on understanding of why, when and how behaviours happen and what purposes they serve (via the use of functional assessment)
Positive Behavioural Support
Focuses on altering triggers for behaviour (in order to reduce the likelihood of the behaviour occurring) Stimulus based interventions Interspersal training Expansion of choice Curricular modification Manipulation of setting events
Positive Behavioural Support
Uses skill teaching as a central intervention (as deficiencies in adaptive skills are often key contributing factors in behavioural challenges) Reinforcement based interventions Functional Communication Training Self Management
Positive Behavioural Support
Uses changes in quality of life as both an intervention and outcome measure
Positive Behavioural Support
Has a long-term focus (in that challenging behaviours are often of a long-term nature and successful interventions need to be maintained over prolonged periods)
Positive Behavioural Support
Has a multi-component focus (reflecting that the fact that challenging behaviours are often multiply determined and also that users typically display multiple forms)
Positive Behavioural Support
Reduces or eliminates the use of punishment approaches)
Positive Behavioural Support
Includes both proactive strategies for changing behaviour and reactive strategies for managing behaviour when it occurs (because even the most effective change strategies may not completely eliminate risk behaviours from behavioural repertoires) Allen et al. (2005)
The Time-Intensity Model of Aggressive Incidents The physiological, emotional & physical path
Early Intervention Reactive Management Post-crisis Intervention Prevention Baseline Trigger Escalation Crisis Remorse & Baseline Recovery Kaplan & Wheeler (1983)
Positive Behavioural Support
At the present time, PBS approaches would therefore appear to offer the most ethically stringent, evidence-based intervention option for people with learning disabilities and challenging needs. As such, PBS may be said to represent a socially valid intervention approach. Allen et al. (2005)
Positive Behavioural Support
UK research shows that only 2-20% of people in need of such interventions actually receive any kind of behavioural support Oliver et al, 1987; Harris & Russell, 1987; Qureshi, 1994
50-60% of people with learning disabilities who challenge will be in receipt of psychotropic (typically anti-psychotic) medication Kiernan et al, 1995; Fleming et al, 1996
Cochrane Review
‘
It is debatable whether use of antipsychotic medication for certain people with a learning disability and challenging behaviour is ethical outside of a randomised control trial
Brylewski & Duggan, 1999
50% or more will be regularly restrained Emerson (2002)
The Rhetoric Gap
What works best is used least and what works least is used most
Possible Explanations
Lack of PBS trained staff Cost Prejudice
