Brief video intervention to increase treatment-seeking among individuals living in a conflict zone: A randomized controlled trial

Background: On October 7, 2023, a large-scale attack in Southern Israel and the ensuing war led to widespread casualties and the displacement of hundreds of thousands in Southern and Northern Israel. The conflict has exacerbated mental health issues. This randomized controlled trial assessed a brief social-contact-based video intervention on a large sample of individuals living in conflict zones, aiming to examine its effects on increasing treatment-seeking intentions. As a secondary aim, we tested changes in treatment-seeking behavior. Methods: Participants (N = 1,052), civilians in conflict zones in Israel, were randomized into either a brief video-based or a psychoeducational control intervention. The 2.5-minute video featured the personal story of a terrorist attack survivor sharing his traumatic experiences and subsequent mental health struggles. Treatment-seeking intentions were assessed at baseline, immediately post-intervention, and at a 30-day follow-up. Treatment-seeking behavior was assessed at the 30- and 90-day follow-ups. Results: The brief video intervention elicited an immediate increase in treatment-seeking intentions. A significant group-by-time interaction emerged (χ²=10.5, df=2, p=.005; Cohen's d = 0.36), particularly among male viewers (p<.001; d = 0.47). However, these effects were not sustained 30 days after the initial viewing. We found no effect on treatment-seeking behavior. Conclusions: This trial confirms the efficacy of a single brief social-contact-based video intervention in increasing treatment-seeking intentions, among those in conflict-affected areas. Although the impact was brief, this accessible intervention underscores its potential as a strategy to facilitate treatment-seeking intentions.
