A Review of an Approach and Methods of Assessing Risk Arising from Behaviour that
Challenges
Rai Turton
Behaviour that challenges (BtC):
Causes harm or presents risk of harm
A challenge to services:
To support safely in least-restrictive environments with maximal social inclusion
Risk assessment:Estimating the probability and severity of future
harm
A simple example (uncontextualised)HighProbability
MediumProbability
LowProbability
MinorHarm
ModerateHarm
SevereHarm
The need for accurate and contextualised risk assessment
● Under-estimation of risk → harm occurs → increased restriction
● Over-estimation of risk → unnecessary restriction
● Lack of contextualisation → defensive support → unnecessary restriction
Focus of this presentation
This presentation focuses on approaches to risk rating.
Contextualisation is mentioned when appropriate but not properly addressed because it is too large a topic.
Two risk-rating methods developed for people who have LD
The BILD method (Powell, 2005)Included harm: physical injury/illness, criminal
offending and property damage
The Mersey Care method (Greenhill et al., 2008)Includes the same harm and also emotional harm,
restriction and social exclusion
Both methods actuarial, risk rating based on severity and frequency of previous harm
Both assign numerical value to severity of harm and modify ratings according to previous frequency
Both embed risk assessment in support and risk management planning
Example: Rating risks using the BILD method (non-contextualised)
A person who caused small abrasions four times in the past month
● Injury weight = 3
● Frequency weight (4-12 per month) = 9
● Risk score = 12, risk rating = high
A person who caused a broken leg in the past month● Injury weight = 4
● Frequency weight (< 4 per month) = 8
● Risk score = 12, risk rating = high
Sources of information
● Carers' records, e.g. care notes, daily diaries● Incident reports● Formalised records of aggression, e.g. Overt
Aggression Scale● Structured and unstructured observations
“A-B-C” analyses of records will support contextualisation.
In simplified form:In situation X, the risk of (harm) is (rating);In situation Y, the risk of (harm) is (rating).
Strengths and weaknesses of the BILD and Mersey Care methods of risk rating
Strengths:● Objectivity: Focus on previous events and use set
methods to assign values and rate risk● Congruent with harm-based definition of behaviour that
challenges● Can use a range of information-collecting methods
Weaknesses:● Use arbitrary weights● No clear method of contextualising risk
Alternative methodsForensic risk assessment:● Some scales adapted for people who have LD● Predict a limited range of outcomes● Risk factors not well matched to those found for
BtC per se
Challenging behaviour scales:● Limited capture of harm● No established method of deriving risk ratings or
contextualising risk
Suggestions
Use adapted forensic instruments for those cases in which the predicted outcomes and the risk factors are appropriate.
Use the BILD or Mersey Care procedures but be aware of the hazards of their weighting systems.
Identify situational factors that modify risk and qualify risk predictions accordingly.
Contribute to the development of better methods.
