Self-harm is a major public health problem and universal interventions such as contacting individuals by post or telephone following a self-harm episode have received much attention recently. They may also appeal to service providers because of their low cost. However, a widespread introduction of these interventions cannot be justified without a better understanding of whether they work, and if so how.
自伤是一个主要的公共卫生问题，最近人们普遍关注通过邮寄或电话联系自伤事件发生后的个人等通用干预措施。由于这些干预措施成本低，它们可能也会吸引服务提供者。但是，如果不更好地了解这些干预措施是否有效以及如何有效，就不能广泛采用这些干预措施。
