Our experiment takes place within the already existing probability-based online panel survey “Ukrainian Refugees in Germany (BiB/FReDA-Study)". Based on Germany’s population registers, it includes 5000 Ukrainian refugees who arrived in Germany within the first months after the beginning of Russia’s full-scale war against Ukraine in February 2022. Three months before the fourth wave of the panel, we will run a short 10-minute questionnaire. As part of the questionnaire, two randomized treatment groups will watch either the celebrity (T1) or the relatable peer video (T2), while the control group (C) will watch no video. After watching the videos, each group will be asked about attitudes to mental health and help-seeking, and they will be given a phone number to call the platform (a different number for T1 and T2). This provides direct evidence on steps on the relative effect of the two videos on mental health help-seeking behavior. In addition, we will follow the three groups in later panel waves, providing us with measures of help-seeking behavior beyond the platform, well-being, labor market participation, and livelihoods.
