For economic reasons a short version of the HAWIE-R, analoguous to the
WIP, has been developed. HAWIE-R-data from 154 psychiatric patients w
ere drawn on for the investigation and, with the help of a regression
analysis, 4 subtests were selected which would allow for the best poss
ible estimation of intelligence. Statistical analysis of various combi
nations shows small differences. The refore theory orientated selectio
n is preferable.
