The present study is one of the few randomized controlled trials comparing short custodial sentences with community service orders. Between 1993 and 1995, 123 subjects were randomly assigned to community service or immediate custody (of a maximum of 14days) in the Lake of Geneva area (Switzerland). The present study updates results published earlier on a follow-up period of 2years by considering re-convictions and social integration over 11years.

Eleven years later, ex-prisoners were better off, complied better with tax regulations, and did not fare worse regarding employment history or marital status.
