Abstract
Treatment of childhood cancer and its side effects can exert a negative impact on patients' parents. A valid and reliable instrument to measure family functioning in Arabic families was considered to be a vital resource. The Pediatric Quality of Life Inventory (PedsQL) Family Impact Scale and the PedsQL Healthcare Satisfaction Hematology/Oncology Scale - Parent Report were completed by 113 Jordanian parents of children with cancer. Cronbach's alpha coefficient was found to be excellent at 0.93 for the total PedsQL Family Impact Scale, which correlated significantly with the PedsQL Healthcare Satisfaction Hematology/Oncology Scale Parent Report demonstrating good construct validity. The Arabic version of the PedsQL Family Impact Scale is both valid and reliable for use with parents of children with cancer.
