PedsQL Cardiac Module
Pediatric Quality of Life Inventory—Cardiac Module · Also known as: PedsQL 3.0 Cardiac
The PedsQL Cardiac Module is a disease-specific instrument developed by Varni et al. in the mid-2000s to measure quality of life in children and adolescents with cardiac disease aged 2–18 years. Measuring across domains including cardiac symptom impact, activity limitations, and cardiac-related worry, it captures how congenital heart disease, acquired heart disease, and cardiac treatment affect daily functioning and well-being. Used alongside the PedsQL Generic Core Scales, it provides comprehensive assessment of cardiac-specific and general health-related quality of life.

When to use it
The PedsQL Cardiac Module is indicated for children and adolescents aged 2–18 years with congenital or acquired cardiac disease (any type, any severity). It is particularly valuable in pediatric cardiology clinics for longitudinal quality-of-life monitoring, in cardiac rehabilitation programs, in clinical trials evaluating new cardiac interventions or medications, and in transition care planning as adolescents move to adult cardiology. The instrument is not appropriate for children without cardiac disease or for asymptomatic carriers of cardiac risk factors.
Strengths & limitations
- Disease-specific assessment captures cardiac-unique impacts (shortness of breath, activity restriction, cardiac anxiety) that generic measures miss.
- Multi-domain structure identifies specific areas of cardiac burden (e.g., symptoms vs. activity limitation vs. emotional impact), enabling targeted interventions.
- Parallel child and parent versions enable assessment of child experience and parental perception; discrepancies often reveal opportunities for intervention (e.g., parental overprotectiveness).
- Integrates with PedsQL Generic Core Scales for comprehensive QoL measurement spanning disease-specific and general functioning.
- Responsive to changes in cardiac status, surgical outcomes, and medication adjustments.
- Validated across diverse cardiac diagnoses (congenital and acquired) and ages 2–18 years.
- No published MCID; clinically meaningful change thresholds must be estimated from related instruments or clinical judgment.
- Requires administration of both Cardiac Module and Generic Core Scales; total time is 15–20 minutes, which may be burdensome in busy cardiology clinics.
- Parent-child discrepancies are common, particularly in adolescents; interpretation can be ambiguous when perspectives diverge significantly.
- Limited normative data by cardiac diagnosis or functional class; interpretation relies on baseline-to-follow-up comparison or group means rather than population norms.
- Does not measure cardiac function directly (ejection fraction, hemodynamics); must be paired with objective cardiac assessments for comprehensive evaluation.
Frequently asked
Should I use the PedsQL Cardiac Module alone or with the Generic Core Scales?
Use both. The Cardiac Module captures disease-specific impacts (cardiac symptoms, cardiac worry, activity limitations specific to cardiac disease), while the Generic Core Scales measure general health-related quality of life. Together, they provide comprehensive assessment. Using only the module may miss important impacts on school, peer relationships, or emotional well-being not directly related to cardiac disease.
What is a clinically meaningful change on the PedsQL Cardiac Module?
There is no published MCID specific to the Cardiac Module. Based on other PedsQL modules, improvements of 5–10 points per scale are often considered clinically meaningful. However, clinical meaningfulness should be contextualized to the child's clinical situation and baseline score.
Can I use the Cardiac Module for children with family history of cardiac disease but no diagnosed disease?
No. The Cardiac Module is designed for children with diagnosed cardiac disease. Children at risk for cardiac disease but without a current diagnosis would not have cardiac symptoms or disease-specific limitations, making the module inappropriate. Standard quality-of-life measures (PedsQL Generic Core Scales) would be more suitable if assessing anxiety or preventive health behaviors.
What age range is the PedsQL Cardiac Module validated for?
Child self-report is validated for ages 5–18 years. Parent proxy is available for ages 2–18 years. For very young children (age 2–4), parent proxy is the only option. For adolescents (13–18), self-report is strongly preferred, though parent perspective remains valuable.
