Quality of life of adolescents with cerebral palsy: agreement between self-report and caregiver's report.

The design is cross-sectional, so it cannot show what causes poor quality of life or whether asking adolescents directly changes care. Only adolescents who could understand a screening question and were linked to educational or rehabilitation institutions were included, so results may not apply to adolescents with more severe communication impairment or those not attending services. The study was done in one Brazilian city, and most caregivers were mothers, so the agreement pattern may not generalise to other settings or caregiver types. The paper compares questionnaire reports; it does not test a treatment or show which report is more accurate for every adolescent.

Do not conclude that caregiver reports are wrong or should be discarded. The study shows poor agreement and lower caregiver scores in some domains, but it did not test whether using adolescent self-report improves care, and adolescents who could not self-report were excluded.
