Abstract
Background and aims
Little is known about the quality of life (QoL) of adults with cerebral palsy (CP). This systematic review aimed to examine the extent to which methodological best practices have been applied to achieve valid and informative QoL assessments for this population.
Methods and procedures
Systematic search identified 1097 non-duplicated, quantitative articles assessing self- and/or proxy-reported QoL in samples of adults with CP. Eighteen studies were included and data extraction was conducted for sampling characteristics, selection of informants (self- and proxy-reports), adequacy of administered measures, and examination of age-related specificities.
Outcomes and results
The results revealed discrepancies between conceptual definitions of QoL and their measurement approaches in CP. Most papers relied on self-reports. Most studies were cross-sectional and often based on relatively small samples; the variable of age was considered inconsistently in statistical analyses.
Conclusions and implications
Future strategies to improve the validity and applicability of QoL assessments of adults with CP would include: using a clear definition of QoL aligned with the measurement employed; considering proxy-reports whenever appropriate, to encompass larger samples and a wider range of ability; and using age-stratified analyses, in order to deepen understanding of potentially modifiable variables and paths linked to QoL outcomes.
