Pediatric Quality of Life Inventory Generic Core Scale (PEDSQL Generic Core Scale)
Please visit this website for more information about the instrument: Pediatric Quality of Life Inventory Generic Core Scale
Basic: Acute, Moderate and Mild Traumatic Brain Injury (TBI)
Supplemental: TBI
Short Description of Instrument
Description: Developed in the US in 1998.The PedsQL 4.0 Measurement Model is a modular approach to measuring  health- related quality of life (HRQOL) in healthy children and adolescents and those with acute and chronic health conditions. The PedsQL Measurement Model covers 4 domains: physical (8 items), emotional (5 items), social (5 items) and school (5 items). It provides a total scales score from 23 items, of which 8 are for physical health summary score and 15 are for psychosocial health summary score.
The instrument takes 4 minutes to complete and is translated in multiple international languages including broadcast Spanish. It is usable for parents/guardians of children between the ages of 2 to 18 years (in 4 age groups) and child versions are available for all age groups except the 2–4 years old.
0-100 scale with scores near 0 representing lower QOL and scores near 100 representing higher QOL. Individual subscale scores can also be calculated for each of the four areas of functioning: physical, emotional, social, and school. To score, items are transferred to a 0-100 scale, i.e., 0=100, 1=75, 2=50, 3=25, 4=0. Scores are then averaged to obtain a final score between 0-100.
Administration mode:
Interviewer-administered, proxy-rated, self-administered
Data Colllection mode:
Paper and pen. Self-administered self-report ages 8 and older. Interviewer- administered self-report ages 5–7. Self-administered proxy report ages 2 and older.
Particular Features: PedsQL Disease-Specific Modules are available for asthma, arthritis, cancer, cardiac disease, and diabetes. There is no module at this time for epilepsy.
Psychometric Properties:
Reliability: Over all 23 multi-item scales had internal consistency reliabilities averaging 0.80. The total scale score had a=0.88 for child and a=0.90 for parent report.
Validity of scales: Distinguishes between healthy children and children with acute and chronic health conditions; distinguishes disease severity within a chronic health condition.
Sensitivity to Change: One article showed that children with epilepsy had impairments in HRQOL but there were no differences in the parent proxy scorings between a single seizure population and a newly diagnosed untreated population. Therefore it is likely that the PedsQL will not be sensitive to change as a result of treatment of epilepsy.
Relationships to other variables: One article showed that HRQOL in siblings of children with intractable epilepsy may also be lower than average.
Strengths and weaknesses:
Strengths: Short and easy to complete. Widely used and validated in US. Has many translations. Broad measurement of function collected in under 4 minutes
Nothing specific noted in publications on the studies listed above, although a reliable mitochondrial disease-specific module does not exist. PedsQL 4.0 has been described as one of the three available general measures of QOL in childhood and adolescence with adequate psychometric properties for application in clinical research.
