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

This study was conducted to examine an adaptation of the Vineland Adaptive Behavior Scale (VABS) [Sparrow, S. S., Balla, D. A., & Cicchetti, D. V. (1984). The Vineland Adaptive Behavior Scales. Circle Pines, MN: America Guidance Service; Sparrow, S. S., Balla, D. A., & Cicchetti, D. V. (2005). Vineland Adaptive Behavior Scales Second Edition Survey Forms Manual. AGS Publishing] and its psychometric properties in Vietnamese culture. The 1984 version of VABS was translated and adapted to form the Vietnamese version of the Vineland Adaptive Behavior Scales (VVABS). The scale was administered to 120 Vietnamese mothers of non-disabled preschool-age children enrolled in kindergarten programs. It was found that the VVABS has acceptable levels of internal consistency reliability and construct validity, and could discriminate successfully between Vietnamese children with intellectual disabilities from those of typical development. The results that were comparable to the VABS indicate a successful adaptation of the construct and measure of adaptive behavior to a non-western culture.
