Expatriates need to deal with numerous stimuli resulting from new environmental and cultural influences abroad,contributing to stress and high rates of failure and turnover. Based on conservation-of-resources theory, this studyaims to explore the role of resources (including sensory processing sensitivity (SPS) and social capital) in explainingexpatriates’ perceived stress and turnover intention. This is the first study to examine the personality trait SPS in thefield of expatriate management. High-SPS individuals tend to be easily overwhelmed by novel stimuli. Based on adataset of 311 expatriates, structural equation model (SEM) and mediation analyses proved full mediation of thepositive relation between SPS and turnover intention through perceived stress. Moreover, stress fully mediated thenegative relation between bonding social capital and turnover intention. While 20% of the domestic population areassumed to show high SPS, we found a 26.4% ratio in our expatriate sample. Implications for both managementand research are derived.
