Sammanfattning
Original psychometric instruments are usually too lengthy and space-consuming to be suitable
for general population based health studies. Usually, however, they can be abbreviated without
losing more measurement precision than what can be accepted in such studies. Here we
demonstrate that short-form versions of three instruments which are part of the MoBa study, and
which include from one third to half the items in the original versions, correlate from 0.90 to 0.96 with
the original version. This means that the short-form versions measure approximately the same
characteristics as do the original instruments, and that they can safely be used for research
purposes in MoBa.
