|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.
Interviewer-administered, proxy-rated, self-administered
Data Collection 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.
The PedsQL covers a wide age range, it has been well used and has reasonable psychometrics. It captures something that the NeuroRehab Infant Pediatrics subgroup agrees is important for almost all NeuroRehab scientific studies, especially clinical trials.
There is an infant version for children 1-24 months. The infant scales include two age-appropriate versions for ages 1-12 months and 13-24 months and assess parents' perceptions of their infant's generic HRQOL. The 36-item PedsQL™ Infant Scales 1-12 months Version encompasses 5 scales: (1) Physical Functioning (6 items), (2) Physical Symptoms (10 items), (3) Emotional Functioning (12 items), (4) Social Functioning (4 items), and (5) Cognitive Functioning (4 items). The 45-item PedsQL™ Infant Scales 13-24 months Version contains the same 5 scales and the same 36 items as the 1-12 months Version with 9 additional age-appropriate items: (1) Physical Functioning (9 items), (2) Physical Symptoms (10 items), (3) Emotional Functioning (12 items), (4) Social Functioning (5 items), and (5) Cognitive Functioning (9 items). For the infant scales, the total score internal consistency reliability was a=.92.
|Scoring and Psychometric Properties||
Scoring: The generic core contains 23 items encompassing four areas: physical, emotional, social, and school. Participants respond on a Likert scale from 0 to 4. Items are reverse scored and linearly transformed to a 0 to 100 scale, with higher converted scores indicating better HRQOL. The instrument provides four domain scores, two summary scores (physical and psychosocial functioning), and a total HRQOL score.
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.
Psychometric Properties: Well-standardized and validated, good reliability and sensitivity to change, good correlations with other standardized measures of disease severity in disease-specific modules.
Reliability: For the generic core, 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.
Headache specific data is also supportive of the reliability (internal consistency and test-retest) and validity (criterion related, convergent, known-groups, and responsiveness to intervention) of the PedsQL 4.0 within a pediatric headache sample.
Particular Features: PedsQL Disease-Specific Modules are available for asthma, arthritis, cancer, cardiac disease, and diabetes.
PedsQL is short, easy to complete, and is widely used and validated in US. It also has many translations. Lastly, it is a 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 (NINDS Headache CDEs). It is an overall quality of life tool that does not focus on either epilepsy or its treatment.
