Abstract

 

Introduction: This study examined the convergent validity of the visual perceptual Richmond Reversal Rating (RRR) assessment, in relation to visual-spatial abilities of young school-aged children, using known-groups validity and convergent validity hypotheses testing.

Methods:Seventy-two primary school children (Years 1-3) were assessed with the RRR assessment and the Spatial Awareness Skills Program Test (SASP).

Results: The Kruskal-Wallis test demonstrated a significant difference between the RRR overall scores and the SAPS grouped scores, H(2) = 6.155, p = .046. Spearman's correlation coefficient revealed a low positive yet significant correlation (rs = .433, p = .000) between the RRR overall scores and the SASP percentile scores, and a significant moderate positive correlation between the RRR overall scores and the SASP scores (rs = .666, p = .000). The results provide evidential support for the convergent validity of the RRR assessment in relation to visual-spatial abilities as measured by the SASP.
