For this study, a number of variables were used to control for the effect of certain factors on the tests of relationships between variables. For example, time in the host country, having accompanying family members during assignments, fluency of local language and having previous experience acted as control variables. They remain constant while testing for the relationships between variables carried out so that the results would be more reflective of the actual conditions. The adoption of these variables is in line with previous expatriate related research (Black & Mendenhall, 1990; Caligiuri, 2000; Mendenhall & Oddou, 1985). None of the control variables had any significant impact on any of the adjustment variables.
