Validitätsstudie zum HAWIK-IV im Vergleich zum HAWIK-III

This study deals with the comparison of the German WISC-IV and its predecessor, the Germen WISC-III; both intelligence test batteries for children aged between 6 and 16 years. Both test versions were administered to 223 children in counterbalanced order. Substantive correlations were found for the Full Scale IQ as well as the Composite and Scale Scores. The highest correlations were found between the scales in which the least changes were made in the new test version whereas the scales with more differences in the subtest structure showed lower correlations. Ranges of expected WISC-IV composite scores were calculated for selected WISC-III IQ scores to give a guideline which WISC-IV score can be expected if the WISC-III score is available. The authors recommend using the recent version of the HAWIK as a general rule. Only if the HAWIK-III was applied before an intervention or training it is advisable to administer the HAWIK-III again to examine the effects of the intervention or training.
