Psychological well-being of Portuguese expatriates in Sub-Saharan Africa: a cross-sectional study

Background: Psychological health problems are highlighted among the most relevant disease patterns in expatriates. The purpose of this study was to determine the psychological well-being in Portuguese expatriates in Angola and Mozambique, considering the increasing expatriation wave. Methods: A cross-sectional self-administered web survey was conducted in a sample of 352 Portuguese civil expatriates in Angola and Mozambique. Clinically significant psychological distress was determined using General Health Questionnaire (GHQ)-12 and associated factors were studied using multiple logistic regression analysis. Results: GHQ-12 items showed good internal consistency as reflected by the Cronbach's alpha. One-third of the screened expatriates corresponded to cases of clinically significant psychological distress. Age, country of birth, self-reported psychological symptoms and self-perception of general health in the previous 3 months were identified as independent variables associated with psychological distress. Conclusions: Increasing awareness and monitoring expatriates mental health should be in the health agenda, furthermore considering them a risk group in need of evidence-based mental health expatriate preparedness. The use of user-friendly validated tools, such as GHQ-12, allowing objective assessment and surveillance of these hard to reach populations should be reinforced.
