Assessment of intelligence of 6-year-old children - practical comparability of HAWIVA-III and HAWIK-IV

Objective: The present study focuses on the practical comparability of HAWIVA-III and HAWIK-IV test results. Method: HAWIVA-III and HAWIK-IV were administered in counterbalanced order to N = 45 6-year-old children. The study presents means, standard deviations, and uncorrected and corrected correlations, as well as standard differences. Regression analysis was used to predict IQ values. Results: There is a significant positive correlation between indices of HAWIVA-III and HAWIK-IV (VT/SV: r =.81; HT/WLD: r = .86; VG/VG: r = .77) and between the two Full Scale IQs (r = .91). Predicted WISC-IV values based on WPPSI-III indices are reported. Conclusion: The results of this study indicate that there is a close relation between HAWIVA-III and HAWIK-IV. Therefore, HAWIK-IV-results can be compared with diagnostic findings assessed by HAWIVA-III.
