Abstract

Background: To translate and investigate the validity and test-retest reliability of the Vietnamese Paediatric Evaluation of Disability Inventory (vPEDI).

Methods: The PEDI was translated and adapted following established guidelines, including forward translation, reconciliation and back translation. Content validity was assessed by expert panels, and the Iitem-Content Validity Index (I-CVI), universal Agreement among experts Scale-Content Validity Index (S-CVI/UA) and the Average CVI (S-CVI/Ave) were calculated. The kappa statistics tested the level of agreement among content experts. The face validity was assessed by determining the percentage of each level of the rating of easiness to understand as rated by 32 caregivers. A total of 446 Vietnamese children ages 6-90 months were recruited to assess the normal raw scores by administering the Vietnamese PEDI. From this total, 50 children were evaluated twice within 2 weeks to examine the test-retest reliability of the vPEDI using intraclass correlation coefficients (ICC) and Bland-Altman analysis.

Results: The vPEDI required minor modifications to be responsive to the culture and typical daily activities in Vietnam. The I-CVI for all domains was above 0.8. The S-CVI/UA and S-CVI/Ave for clarity and relevance were from 0.78 to 0.98. Face validity ratings indicated high understandability. The test-retest reliability of all domains was excellent with ICCs above 0.93.

Conclusion: The vPEDI is a valid and reliable tool for assessing functional abilities in Vietnamese children. Healthcare providers can use the vPEDI to set individual goals and guide intervention strategies for contexts and environments relevant to Vietnam.
