Small, significant long-term effects of social norm interventions on pro-environmental behavior: new meta-analysis (~22-month FU). Even small shifts matter at scale, but we need to boost effectiveness. Thank you Frederike Lemmel & @tholehoppen.bsky.social, #climatechange: doi.org/10.1016/j.je...

🎉Excited to share that our new meta-analysis has just been published in The British Journal of Psychiatry! Exploring how effectively psychological interventions for adult PTSD alleviate comorbid depression—the first comprehensive meta-analysis on this matter convering all psychological interv. 1/5

Meta-analysis of 79 controlled trials (1M+ participants) shows social comparison boosts pro-environmental, health & performance behaviors. Effects are small, but the intervention is very low-cost—and its efficacy can be enhanced. A promising tool for behavior change. Outstanding work, Thole & Rieke.

In this longitudinal study coordinated by Dana Churbaji, we tracked PTSD, depression & anxiety in war survivors in NW Syria after the 2023 earthquakes. Despite recovery trends, prevalence stayed high. RNT predicted worse outcomes. Open access: doi.org/10.1192/bjp....
