Are You Okay? Effects of a National Peer-Support Campaign on Mental Health

Peer-to-peer support is often a critical component of mental health programs, but evidence on the effect of peer-based support programs at scale is limited. Using quasi-experimental methods, we examine whether a prominent peer-based support campaign, “R U OK? Day”, affects short-term mental health outcomes in Australia. Using variation in daily records and differences in the campaign’s intensity over nine years, we find no evidence that “R U OK? Day” reduces suicides and suicidal behaviours in the month after the campaign. However, we find positive effects on mental wellbeing, particularly among middle-aged males, with improved social support the likely mechanism. Our results provide evidence that peer support campaigns may be a practical, low-cost approach to improve population mental wellbeing.
