Psychometric properties and validation of the Polish CP QOL-Child questionnaire: a pilot study
Sammanfattning
Aim: Translate, determine the psychometric properties
and validate the Polish CP QOL-Child questionnaire.
Materials and methods: A double translation of the questionnaire
from English into Polish and back was executed.
The questionnaire was distributed to 55 parents/legal
guardians of children with cerebral palsy aged 4–12 years.
The psychometric properties of the questionnaire were
determined on the basis of its internal consistency and
the internal consistency of each of the investigated
aspects, as well as on the assessment of the relationship
between quality of life and such data as child’s age,
parent’s age, place of residence and GMFCS level.
Results: The results showed high levels of internal consistency
of the Polish version of the CP QOL-Child questionnaire
- Cronbach’s alpha was between 0.77 and 0.82,
which is comparable to the original scale, where it was
0.74-0.92. In addition, we found no relationship between
child’s age and parent’s age and the child’s quality of life.
Whereas we determined dependencies between the
child’s GMFCS level and quality of life in areas such as
emotional state (p = 0.025), pain and the effects of disability
(p = 0.033), and to a lesser extent participation in
social life (p = 0.045). However, Spearman test presented
that only domain pain and impact of disability reported
positive correlation r = 0.43.
Conclusion: Studies showed that English language the CP
QOL-Child questionnaire was successful translated into
Polish which is confirmed by the results of the assessment
of the psychometric properties and validation of
the Polish language questionnaire. The results of our
study indicate that the Polish language version of the CP
QOL-Child questionnaire is an appropriate tool to assess
the quality of life of Polish-speaking children with cerebral
palsy aged 4-12 years. Published by arrangement with John Wiley & Sons.
