Validation of the Vineland Adaptive Behavior Scale in Arabic Language within a Palestinian Context

Abstract

The purpose of this investigation was to determine if an Arabic version of the Vineland Adaptive Behavior Scale (VABS-II) could be employed to measure adaptive behaviors of children in the Palestinian context. This was a non-experimental study design with a convenient sample examining the correlation of the scores on the two tests domains; VABS-II and Portage scale domains. Two samples of participants within the ages 2-9 were analyzed; including a group of high-risk children (N = 26) and control group (N = 30). Results demonstrated that VABS-II is an appropriate scale for assessing adaptive and maladaptive behaviors in a Palestinian context as it meets the standard of previously validated measures while adding scales of interest not available in the Portage.
