We controlled for several demographic variables that were not
of direct interest but have been shown in prior studies to be related
to employee creativity (Janssen, 2004; Shin and Zhou, 2003), such as
age, gender, education, and year(s) with current company. Gender
was coded as 1 = female and 0 =male. Education was coded into
two categories (University level or above = 1 and Secondary level
or below = 0). Age and tenure were assessed in terms of years.
