Abstract:
Behaviourally-based
interventions for parents, such as the Webster-Stratton group parenting programme,
have been found to be clinically effective in reducing behavioural problems
in children in both the short and long term. However, their cost-effectiveness,
both short and longer-term, has rarely been examined.
This
paper describes a cost-effectiveness analysis being undertaken alongside the
Hutchings et. al study in which families with a young child identified as
at risk of developing conduct disorders are participating in a randomised
control trial of the Webster-Stratton group parenting programme. The study
includes a treatment group and a waiting list control group that will receive
the intervention after six months. The Eyberg Child Behavior Inventory (ECBI),
one of a number of clinical measures being collected at baseline, twelve months
and eighteen months, is being used as a measure of clinical effectiveness
in the cost-effectiveness analysis.
Cost
data is being collected, at baseline and the same follow-up points as the
clinical outcomes, on the use, by the children, of health, social and special
educational services by means of a Client Service Receipt Inventory (CSRI).
The health data provided by the CSRI will be checked for reliability by consulting
the GP records of a sub-sample of participants. Costs related to the provision
of the intervention in terms of therapeutic contact time are being gathered
from a number of the research groups including those at Caernarfon, Oswestry
and Rhyl. All costs will be estimated from a multi-sectoral public service
perspective. These costs will then be used in an incremental cost-effectiveness
analysis.
Although
no results are presently available from this aspect of the research the paper
will describe the design, measures and rationale for the cost effectiveness
arm of the research.
