Postcards in Persia: randomised controlled trial to reduce suicidal behaviours 12 months after hospital-treated self-poisoning BJP April 2011 198: 309-316; published … (original) (raw)

This study reports on a randomized controlled trial aimed at evaluating the effectiveness of a postcard intervention combined with usual treatment (TAU) against TAU alone for reducing suicidal behaviors among patients who have previously self-poisoned. Conducted in a non-Western setting, the study includes a significant sample of 2,113 participants. Primary outcomes measured were suicidal ideation, suicide attempts, and self-cutting. The trial found that the postcard intervention was associated with a significant reduction in suicide attempts, particularly among females and those with previous suicide attempts, indicating its potential as an effective intervention in the context of post-self-harm care.
