ABSTRACT
Epilepsy is the most common chronic neurological condition in childhood.
However, minimal attention has been paid to the child’s concerns about
epilepsy in relation to the everyday but important parts of the child’s
life for example: school career, family holidays and personal relationships.
Recent research with adults suggests that subjective measurement methods
should be incorporated in quality of life (QoL) test batteries. Up to now
such methods have not been developed for children with epilepsy.
In this research we survey the methods and instruments which can be
used to measure the quality of life of children with epilepsy. We examine
health related QoL instruments which have been used both in the study of
children with epilepsy and other handicaps and examine the aims and dimensions
of these instruments in relation to epilepsy. The results of this theoretical
study are summarised into specific hypotheses concerning the measurement
of QoL relevant to children with epilepsy. Practical questions for the
project have been how the measurement of QoL can be related to medical
variables and the criteria for measurement related to children of different
ages.
Quality of Life measurement in Children with Epilepsy
Introduction
The need to measure childrens’ perceptions of the intensity of symptoms
associated with different treatments and quality of life has been neglected.
In this poster, some of the possibilities and problems for the measurement
of Quality of Life (QoL) in children will be explored.
1. Why measure QoL in children?
As a basis for interventions.
As issues of importance to the child are identified, it should be possible
to optimise outcomes by developing more appropriate interventions.
To compare clinical trials
Accurate measures that reflect the impact of treatment from the childâs
perspective are urgently needed.
2. Why child-specific measures?
Developmental differences
Child development is rapid and the social and behavioural effects of a
diagnosis of epilepsy are dependent on the age at diagnosis.
Age dependent interpretations of QoL.
“Getting on at school” may have a social meaning to the young child and
an academic meaning to the adolescent.
Friendship patterns change with age.
“Good health” for younger children can mean the ability to perform ‘Superman
acts’.
3. Methodological problems
a) Reliability
The argument for a reliable instrument needs to be balanced against
the inevitable change that accompanies the development of any child.
b) Positive / negative self-presentation
Children may wish to present a more positive image or alternatively
socially undesirable behaviour and defiance.
c) Parent vs. self-ratings
-
Limitations of parents’ ratings are:
1) reflects parents’ own anxiety;
2) unreliable on emotions.
Even reports of external factors may not be accurate e.g. concerning
difficulties at school or in interactions with friends.
-
Limitations of self-rating are:
1) limited cognitive and linguistic skills
2) Expression of symptoms is highly dependent on parental influence.
4. Symptoms
a) Subjective measurement problems.
Child not able to understand or explain internalisation of social/health
problems.
Distress may be sub-conscious and difficult to express or even recognise
for younger children.
b) Objective measurement problems.
Validity doubtful when scales need to be simplified and danger of
experimental bias where scales need to be explained.

6. Discussion
In selecting a scale, consideration needs to be given to:
1) the purpose of assessment,
2) the time available and
3) whether or not it is possible to elicit information directly from
the child.
There is very little reliability or validity data available for epilepsy-specific
measures.
All measures should consider developmental differences in QoL and how
concerns change with maturity.
There is a need for a more theoretical approach, probably based on
normative developmental psychology.
