Johannesburg, 28 August 2014 / In previous research done, convergent validity was not established for OT-APST with two cognitive-perceptual tests. In this research, the DLOTCA and RPAB were used as reference tools to determine the convergent validity of the OT-APST using Spearman’s correlation. The aim was to ascertain whether the three tests when administered at the same time would yield the same result. This was a quantitative cross-sectional study that was mainly correlative and comparative in nature. Convenience sampling was used (n=32). The tools compared evaluate similar constructs and were expected to have strong correlations. This current research revealed that six subscales of the OT-APST had significant correlations with similar cognitive areas from the DLOTCA and the OT-APST subscales often correlated with an appropriate item from the RPAB. This study provides sufficient evidence of the convergent validity of the OT-APST when compared to the DLOTCA and RPAB. The OT-APST proved useful in identifying patients with visual perceptual problems in a population not standardised for.
