Procedures
RECRUITMENT
Recruitment and data collection were initiated online using the snowballing technique. Upon consent, participants were able to fill in the baseline survey (T0). Then, each consented participant received ten messages over 5 weeks, at a rate of two messages per week, that is, every Monday and Thursday starting the first week after consent. An additional online survey (follow-up 1, T1) was administered right at the end of the intervention (i.e. after week five) and then again 5 weeks post-intervention (follow-up 2, T2). Then, after follow-up 2, the participant irrespective of the allocated group received a debriefing video that explains IE principles with practical tips and examples. The surveys, messages and videos were provided in both Arabic and English.
