The present study is the first to examine empirically whether required fields in online surveys impair reliability and response pattern, as participants forced to respond to all items may provide arbitrary answers. Two hundred and thirteen participants completed a survey consisting of six questionnaires testing personal and social issues and perceptions. They were randomly assigned to one of two versions of the survey: optional-fields (N = 104) or required-fields (N = 109). Comparison of the Cronbach’s alpha of the two versions revealed identical reliability values for all questionnaires, save for somatization, where a minor difference was found. Confirmatory factor analysis showed no difference in the factor structure of the two versions, and no differences were found by Bayesian t-test and Levene’s test for equality of variances. The findings suggest that required fields do not impair reliability or change the response pattern, and therefore can be used in online surveys to prevent missing data.

Migration inevitably involves difficulties. These difficulties are more pronounced for refugees and asylum seekers, who also often suffer discrimination. In this study, we examined the impact of living difficulties on the psychological wellbeing of Darfuri asylum seekers in Israel. Based on the stress process theory, we hypothesized that perceived discrimination mediates the relationship between living difficulties and psychological distress, post-traumatic stress disorder (PTSD), and psychological quality of life. The sample consisted of 300 Darfuri asylum seekers aged 19 or older. Measures included post-migration living difficulties, perceived discrimination, psychological distress, PTSD, psychological quality of life, and demographic factors. The results show that greater living difficulties were associated with lower psychological quality of life, higher PTSD symptoms, and increased psychological distress. As hypothesized, perceived discrimination fully mediated the relation between living difficulties and psychological quality of life and PTSD symptoms. Additionally, perceived discrimination partly mediated the relation between living difficulties and psychological distress. Our findings support the stress process theory and the role of society in stressful situations. It also indicates that by reducing perceived discrimination, psychological wellbeing can be improved.
