An investigation into the Ward and Hudson self-regulation model with sex offenders who have intellectual disabilities
|
Background
Recent research into sex offending focuses upon the offence chain. The Self-Regulation
Model represents a conceptual advance, as unlike previous models of the offence chain,
it can account for offenders who intend to commit offences. It consists of four pathways
which comprise two goal types and two strategy types. This study aimed to ascertain
whether or not this model could be used to classify a sample of men with intellectual
disabilities who had committed sexual offences. It was hypothesised that if reliable
classification was possible, the participants should differ by goal type and strategy type
on several psychometric and demographic variables.
Method
The study utilised a cross sectional independent between groups design and adapted the
methodology used in a previous study (Bickley & Beech, 2002). Thirty four participants
from an ongoing treatment study were classified according to the model and data
gathered for the ongoing project were used to test the hypotheses.
Results
The participants were classified with 81% interrater reliability and were distributed
across the four pathways in similar proportions to two previous studies (Bickley &
Beech, 2002; Keeling, Rose, & Beech, in press). The expected differences between goal
types and between strategy types were not found. However, those with an avoidancegoal had been reported to the police more frequently and had received more previous
convictions than those with an approach goal who committed more serious offences. The
only difference between strategy types related to the approach offenders. The approach
automatic offenders showed significantly more shame than approach explicit offenders
when others discovered they had committed an offence.
Conclusion
The capacity of the Self-Regulation Model to account for offenders who intend to
commit offences signifies that it is a useful model for conceptualising the offences of
men with intellectual disabilities. Why sex offenders with intellectual disabilities did not
differ according to goal type and strategy type in the same ways as sex offenders without
intellectual disabilities is considered and the implications for the model are discussed
