PedsQL Diabetes Module
Pediatric Quality of Life Inventory—Diabetes Module · Also known as: PedsQL 3.0 Diabetes
The PedsQL Diabetes Module is a 28-item disease-specific instrument developed by Varni et al. in 2003 to measure quality of life in children and adolescents with type 1 and type 2 diabetes. It captures the impact of diabetes management, glucose monitoring, and disease-related worry on daily functioning. The module is paired with the PedsQL Generic Core Scales, enabling both disease-specific and general health-related quality of life assessment.

When to use it
The PedsQL Diabetes Module is indicated for children and adolescents aged 2–18 years with type 1 or type 2 diabetes. It is particularly valuable in diabetes education programs, in trials evaluating new insulin regimens or continuous glucose monitoring systems, in assessing the psychosocial impact of diabetes diagnosis, and in identifying quality-of-life barriers in longitudinal diabetes care. Use alongside the PedsQL Generic Core Scales for comprehensive assessment. The instrument is not appropriate for children without diabetes or for adult populations with diabetes.
Strengths & limitations
- Disease-specific assessment captures diabetes-unique burden (glucose monitoring, injection anxiety, hypoglycemia worry) that generic QoL measures miss.
- Parallel child self-report and parent proxy versions enable comparison of perspectives and assessment of young children.
- Integrates seamlessly with PedsQL Generic Core Scales for both specific and general health-related quality of life measurement.
- Validated in both type 1 and type 2 diabetes, enabling cross-disease comparisons.
- Demonstrates good internal consistency (Cronbach's α >0.70 for most scales) and test-retest reliability.
- Responsive to improvements in diabetes management and new technologies (e.g., continuous glucose monitoring).
- No established MCID for the PedsQL Diabetes Module; clinically meaningful change threshold must be estimated from other PedsQL modules or expert consensus.
- Requires use of both the Disease-Specific Module and Generic Core Scales for comprehensive assessment, increasing administration time compared to standalone instruments.
- Limited normative data for comparison; most interpretation relies on baseline-to-follow-up or group-to-group comparisons rather than population norms.
- Self-report dependent on literacy and abstract thinking; may be limited for children <5 years.
- Does not assess glycemic control directly; must be paired with HbA1c or glucose monitoring data to contextualize quality of life.
Frequently asked
Should I use the PedsQL Diabetes Module alone or with the Generic Core Scales?
Use both together. The Diabetes Module captures disease-specific burden (glucose monitoring, injections, disease worry), while the Generic Core Scales measure general health-related quality of life (physical, emotional, social, school functioning). Together, they provide a comprehensive assessment. Using only the module may miss important impacts on general functioning.
What is a clinically meaningful change on the PedsQL Diabetes Module?
There is no published MCID for the Diabetes Module specifically. Studies in other PedsQL modules suggest that 3–5 points per scale represents meaningful change. In diabetes research, improvements of 5–10 points per scale are often considered clinically relevant, though this should be tailored to the specific intervention and population being studied.
Can I use this with both type 1 and type 2 diabetes?
Yes. The PedsQL Diabetes Module was validated in both type 1 and type 2 diabetes populations and captures burdens common to both (glucose monitoring, medication adherence, disease worry). However, the relative importance of certain items may differ; a child with type 2 diabetes managed by oral medication may have lower scores on injection-related items than a child on insulin.
What age range is the PedsQL Diabetes Module appropriate 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 as teenagers' perceptions of their own quality of life may differ significantly from parent perceptions.
