Background: The Pediatric Evaluation of Disability Inventory (PEDI) is an assessment to evaluate children’s performance in activities of daily living.

Aims: The study investigated if the normative standard scores of the PEDI are applicable to the German version of the PEDI (PEDI-G) in Germany, Austria and Switzerland, and whether there are differences in the applicability of the PEDI-G between the three countries.

Materials and methods: 75 children with normal development (35 girls, 40 boys) from Germany (n = 17), Austria (n = 16), and Switzerland (n = 42) aged between 0.9 month and 7.3 years (SD = 2.03) participated in the study. Descriptive statistics, independent samples t-tests, univariate analyses of variance (ANOVA) and post hoc Tukey tests were applied.

Results: No significant differences were identified. However, the German-speaking sample showed higher scores for the domain social function in both scales and in the Caregiver Assistance Scale self-care. Lower scores were identified in the Functional Skills Scale mobility.

Conclusions and significance: The results support that the normative standard scores of the PEDI are applicable to the PEDI-G and for Austria, Germany and Switzerland, as no significant differences between the countries were identified. However, the generalizability of the results is limited due to sample size and recruitment procedures.
