Reliability and validity of the Vietnamese Vineland Adaptive Behavior Scales with preschool-age children.

Lawer et al. (2009) translated the Vineland Adaptive Behavior Scales into Vietnamese. They then checked if the new version still measured the same skills reliably in preschool children.

The team gave the scales to parents of kids with and without intellectual disability. They wanted to see if scores could tell the two groups apart.

The Vietnamese Vineland worked. It gave steady scores when used again and clearly separated children with intellectual disability from typically developing peers.

In short, the tool is trustworthy for Vietnamese preschoolers.

de Bildt et al. (2005) had already shown the original Vineland is reliable in kids with intellectual disability. R et al. built on that by proving the Vietnamese translation keeps the same quality.

Green et al. (2020) later found that the newer Vineland-3 gives lower scores than the old Vineland-II. That update now supersedes the version R et al. used, so clinicians today should switch to Vineland-3 and expect scores to run 10–20 points lower.

Lam et al. (2009) put the Vietnamese scales to work right away. They used them as the outcome measure in a home-based parent-training study, showing the tool can catch real skill gains in Vietnamese children with intellectual disability.

Tan et al. (2014) did a similar cultural adaptation in rural Zambia. Both projects show the Vineland can travel across languages and settings when carefully translated.

If you assess Vietnamese preschoolers, you can trust the Vietnamese Vineland. Just remember that newer Vineland-3 norms give lower scores, so update your interpretation. The tool is ready for both diagnosis and tracking progress in early-intervention programs.
