Abstract

VENTER, Lucinda; RICHMOND, Janet  and  TAYLOR, Myra F. Convergent validity of the Richmond Reversal Rating in relation to visual-spatial perception as measured by the SASP. S. Afr. j. occup. ther. [online]. 2018, vol.48, n.3, pp.24-30. ISSN 2310-3833.  http://dx.doi.org/10.17159/2310-3833/2017/vol48n3a5.

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