Abstract
The study was primarily concerned with the development of norms of
adapted VCI subtests (Ambreen & Kamal, 2011) of WISC-IV UK
(Wechsler, 2003) for Pakistani children. Normative sample comprised of
801 students including both boys and girls. Sample was further divided
into four age groups of 10-11 years, 12-13 years, 14-15 years, and 16-17
years with almost equal number of students in each age group. Three
types of norms including: age based standard scores (scaled scores and
VCI equivalents), percentile, and test-age equivalent norms were
developed for the adapted subtests. All newly developed norms proved
quite appropriate as means and standard deviations for the scaled score of
the subtests, and for VCI equivalents closely approximated the presumed
means and standard deviations for scaled scores (M = 10, SD = 3) and
VCI equivalents (M = 100, SD = 15). The implication of newly
developed norms was assessed through comparing the scaled scores and
VCI equivalents of 100 children when calculated both from new norms
and UK norms. Mean differences showed an increase of 0.38 to 4 points
in scaled scores and 13 points in VCI equivalents when computed and
analyzed with Pakistani norms as compared with the UK norms.
