Research and Quality of Life
It is only in the last few years that major studies have been undertaken which relate
to intervention in the field of quality of life and intellectual disability. Examples
are to be found in the work by
Renwick, Brown and Nagler (1996) and in
Brown, Bayer and Brown (1992). Quality of life is seen as the development
of wellbeing. Felce and Perry (1997)
define five clear areas of wellbeing, which set the theme for a major understanding
of quality of life. These are:
- Physical Wellbeing
- Material Wellbeing
- Social Wellbeing
- Emotional Wellbeing
- Productive Wellbeing
Quality of life is also seen as an holistic role in the life of each individual.
Such perceptions are important, not only from the consumer's point of view, but
from those of other stakeholders, such as parents, spouses and the various professionals
involved. The wide range of components within the quality of life model raise important
questions about research and practice.

Quality of Life Measures
Cummins (1995), in his review of quality of
life measures, mentions over 200 such scales developed to measure different components
of quality of life. Both quantitative and qualitative approaches are seen to be
relevant, and subjective and objective factors are important. Qualitative studies
are particularly relevant at the initial stages in defining a new field. Indeed,
if we look at the harder sciences, we find that naturalistic enquiry has preceded
calibrated measurement. This, for example, is true in the development of biological
concepts such as evolution. It is also true in relation to astronomy. In both these
areas, observation and careful recording precede to more specific, and, ever more
precise, measurement. Quality of life research, then, particularly lends itself
to a broad base of research methodology. Research is sometimes seen as synonymous
with experimental methodology. This is inappropriate. Other methodologies, such
as ethnographic research, discourse analysis, and phenomenology represent approaches
which are clearly described in the literature and are effective in this domain.
Their use appears to solve a wide number of problems and enables us to conceptualise
the nature of disability and our responses to it in rather different ways from those
we have normally associated with this field.
Perceptual Measures
Another important component is the role of consumer perception. Traditionally, perceptual
measures have been seen as subjective, and have largely been disregarded in terms
of science. Yet this is an extraordinary omission for one only has to look at the
traditional sciences to realise that perception has played a dominant role in the
development and formulation of theory and the development of precise measuring tools.
Unfortunately, what individuals say about their understanding of choice, how they
perceive dimensions of life (e.g. how they perceive their carers, and professionals)
are regarded as subjective responses and often with suspicion. My view is that they
are perceptual responses and can be taken to be the way individuals, at particular
points in time, decide to encode their understanding of what is happening. Such
perceptions are capable of meeting quite traditional standards of objectivity. For
example, they may be checked for reliability and, within our own results, test/retest
reliabilities have ranged from about 0.5 to 0.9 (Brown
& Bayer, 1992). This should be regarded as respectable.
In terms of validity, we sometimes find low correlations between the perceptions
of people with Down syndrome, their parents and also professionals. But there is
an interesting reason for this. Continued intervention will often see the emergence
of closer agreement between participants, relatives and professionals, and we are
now using this as a marker of progress. It can also be an effective tool in carrying
out counselling between members of families and professionals as we discuss with
them the different perceptions and help to explain why these exist. The large differences
in perception between individuals and their families is most marked in areas relating
to emotional concerns and issues concerning self-image. The Down syndrome research
of Brown (1991) shows this clearly.
I am arguing that the omission of perceptual data, whether or not regarded as objective
or subjective, does a grave disservice to our understanding of the field of disability,
a view underscored by Andrews (1974) who noted
that individuals respond to what they perceive, rather than objective realities.
What individuals feel about themselves is likely to be a major determinant of behaviour.
The results we have obtained from research on quality of life (Brown, Brown & Bayer,
1994) is marked by an enormous range of variability of behaviour; variability
that increases as individuals undergo involvement in quality of life models. We
found that individuals, including those with Down syndrome, who did not take part
in, for one reason or another, quality of life interventions (that is, choice over
type of activity, place of activity and the individual who is structuring, applying
the activity, or supporting the consumer) did not improve significantly compared
with our quality of life intervention group. One explanation is that when parents
do not believe an individual can benefit from behavioural and social intervention,
he or she is unlikely to make progress. Why parents think progress is or is not
possible is complex, but it is in the interests of the child that the parents have
a positive (but not unrealistic) view of potential progress.
Quality of life intervention amongst persons with Down syndrome resulted in maintaining
self image (i.e. how I see myself getting on in a number of areas) compared with
non-intervention groups whose score tended to decline. This was different from other
persons with intellectual disability and may have been associated with the presence
of an earlier ageing process in persons with Down syndrome. The same effect was
noted in recreation and leisure activities where the intervention group held their
performance while those without quality of life intervention declined (Brown, 1991).
This raises the interesting hypothesis that quality of life intervention around
recreation and lifestyle may help to withstand the early ageing process. Leisure
and recreation may reduce decline.
Experimental Versus Other Types of Research
Much research to date has been forced into a quasi-experimental methodology where
experimental and control groups have been contrasted in terms of the efficacy of
the presence or absence of an independent variable. The quality of life model suggests
that there are a range of perceptual measures which may represent critical independent
variables which may be more relevant than intelligence or chronological age. It
is these variables we may need to control if we are to carry out experimental studies.
Until we do this, error factors are likely to be large and many experimental studies
fruitless for, without such control, variability in performance is likely to swamp
differences between groups. We are in danger of finding statistical insignificance
because the perceptual views of the participants are also functioning as causal
independent variables. Of course, all of the above argues for looking at the descriptors
of individuals in terms of perception.
Implications for Future Research
In a number of studies we are attempting to apply some of the quality of life concepts
discussed above to research in Down syndrome.
I) One study concerns issues of awareness and imagery (Brown & Bullitis). Some
may refer to this as consciousness. If we take the quality of life argument seriously,
and recognise that we are dealing increasingly with personal perception, we are
inevitably drawn to issues surrounding whether individuals perceive things clearly
and whether they go through meta-cognitive processes in regard to this awareness.
Some preliminary results on this research suggests that people with Down syndrome
often have very vivid visual mental imagery and use this effectively in humour,
relationships, drama and art. Cautiously, I suggest this is more vivid than in many
other persons with intellectual disability without Down syndrome. If this is correct
it may be relevant to educational, social, community living and employment situations,
and could play a role in education training and rehabilitation.
2) A second study relates to the information provided to mothers of new-born Down
syndrome children by health professionals (Kyrkou, Brown & Thornley). We believe
that this may be not only important for the mother, but critical for how the child
develops later. Negative views about Down syndrome are still provided to mothers
at the birth of their child. These views are likely to influence the perceptions,
attitudes and motivation of the parents. Yet earlier I demonstrated that acceptance
of such views could well influence the way intervention is viewed, including the
self image of the child, which is seen as crucial in many quality of life studies.
We wish to document these early views passed to parents, particularly mothers, and
suggest ways in which more positive, but not unrealistic views, can be presented.
Our aim is to present this material in booklet form to alert parents and professionals
to these concerns.
3) A third study examines leisure, recreation and friendships in adolescents and
young adults with Down syndrome (Bottroff, Duffield & Brown). Leisure and recreational
pursuits can contribute significantly to a person's holistic view of health, stress
reduction, and cognitive stimulation. Such pursuits also offer opportunities to
increase social interactions and develop friendships. Our aim is to investigate
the nature and relationship between individual's participation in leisure and recreation
pursuits and acquisition of friends. We are Investigating their understanding of
concepts associated with friendships and pursuing their understanding of personal
perceptions of these domains in terms of increasing involvement and activity in
social life. All of this has direct relevance to life span issues including support
as individual's age and their ability to form lasting partnerships for the issue
of isolation in later life is a critical one (see
Brown 1995).
4) A fourth study, on aspects of wellbeing in employment for people with Down syndrome
(Grantley, Thornley and Brown) is concerned with employment within open market situations
through individualised placement. The information gained from quality of life studies
argues for the placement of adolescents and adults in individualised and matched
job placements rather than depending on traditional group situations. This individual
support takes into account choices, personal development and individual variability
and provides opportunities to apply support in holistic aspects of living with a
view to enhancing employment activity (eg support at home to get ready for going
to work, nutritional intervention to enhance work performance, activities at home
and community which will support the employment process).
Concluding Comments
This paper illustrates some of the changes in research and practice exemplified
by quality of life studies. The critical relevance of personal perception is discussed.
Finally, some examples of research development in Down syndrome involving quality
of life concepts were briefly described, indicating the way such studies can impact
the aims, direction, structure and interpretation of research and practice.
