Intervention: Psychological First Aid (PFA)
Description: PFA is a WHO developed support strategy that involves humane, supportive and practical help for individuals living in a serious humanitarian crisis. PFA does not necessarily involve a discussion of the event(s) that cause the distress but aims particularly at five basic elements that are crucial to promote in the aftermath of crises, i.e. a sense of safety, calm, self- and community efficacy, connectedness, and hope (Hobfoll et al., 2007). It consists of a conversation (approximately 30-45 minutes) that a helper has with a participant which can be provided remotely (e.g. videoconferencing or telephone). It has various themes; the helper provides non-intruding practical care and support, listen to needs and concerns, helps people to address basic needs (e.g. information), listens to people without pressuring them to talk, comforts people and helps them to feel calm, helps people to connect to information, services, and social support, and protects people from further harm (WHO, 2011).

Intervention: Doing What Matters in Times of Stress (DWM)
Description: DWM is based on the acceptance and commitment therapy (ACT), a form of cognitive-behavioural therapy, with distinct features (Hayes, Levin, Plumb-Vilardaga, Villatte \& Pistorello, 2013). ACT is based on the concept that ongoing attempts to suppress unwanted thoughts and feelings can make these problems worse, so instead it emphasises on learning new ways to accommodate these thoughts and feelings without letting them dominate. ACT has been shown to be useful for a range of mental health issues (Tjak et al., 2015) and has been used successfully in a guided self-help format (Hayes et al., 2013). DWM includes five sections (or modules), each of which focuses on a specific skill. In this study, the DWM program will be delivered as an online intervention. The DWM intervention, i.e. both the audios and the self-help guide, will be adapted for use on a smartphone or other device with internet access.

Intervention: Problem Management Plus (PM+)
Description: PM+ is a brief, psychological intervention program based on cognitive behavioural therapy (CBT) techniques that are empirically supported and formally recommended by the WHO (Dua et al., 2011). The manual involves the following empirically supported elements: problem solving plus stress management, behavioural activation, facing fears, and accessing social support. In these 90-minute sessions participants may talk to trained non-professional helpers (who are supervised by registered (clinical) psychologists). PM+ has four core features: it is brief (five sessions); delivered by non-specialist helpers; transdiagnostic thereby addressing depression, anxiety, PTSD, stress and problems as defined by people themselves; and originally designed for people in low-income country communities but easily adaptable to different (vulnerable) populations, cultures and languages.
