International assignments: The role of social support and personal initiative

This study adapts components of Fay and Frese's nomological network of personal initiative (2001) and Caligiuri and Lazarova's model (2002) for the influence of social support on adjustment. Based thereon, a model for the relationship between personal initiative, social support and work adjustment was developed and tested. One-hundred twenty-seven expatriates answered an online questionnaire during and after their foreign sojourn. Results suggest that personal initiative of the expatriates and social support received from supervisors – but not from their co-workers – predicted job satisfaction, job stress and job performance of the expatriates. Social support and personal initiative have a strong relationship with successful work adjustment. Personal initiative moderates the relationship between social support from co-workers and job performance. There are practical implications for companies that send their staff on international assignments. Implications for the concept of personal initiative in expatriate adjustment research are discussed.
