a strong ITU might prompt someone to seek out and attend BIM training. Equally, relationships seen may be due to the measured variables both being related to an unmeasured third variable, e.g. an employee who has been assigned to a BIM project might score highly on both EOT and ITU without the training having had any actual effect on intention.
