  • PLS Description Scared straight programs involve organised visits to prison by juvenile delinquents or children at risk of committing crime, also called pre-delinquents. Scared straight and similar programs are promoted as a crime prevention strategy, identifying children at risk of committing crime to discourage them from any future criminal conduct. This review assesses the effect of these programs on criminal behaviours by juvenile delinquents or pre-delinquents.

  • PLS Title Exhaustion of unemployment benefits leads to an increase in job-finding rates among the unemployed
  • PLS Description Since the 1970s unemployment rates in Europe and the USA have diverged, with unemployment persistently higher in the USA. The generosity of the benefits system is one possible factor behind this difference. Shortening the length of unemployment benefit eligibility period is a policy instrument intended to decrease unemployment. The policy is intended to encourage productive job searches and reduce the overall unemployment level. This review assesses the impact of exhaustion of employment benefits on the job-finding rate for unemployed individuals

  • PLS Description The share of the working-age population relying on disability and sickness benefits has tended to increase in OECD countries, resulting in negative impacts for the individuals concerned, their families, their employer and society more generally. Workplace disability management (WPDM) is a comprehensive and cohesive employer based approach to managing complex needs of people with a work disability within a given work environment. This review assesses the effectiveness of workplace disability management programs in promoting return to work. It focuses on successful job maintenance and return to work (RTW).

  • Type of document Protocol Review User abstract Plain language summary Previous version
  • PLS Title Incarceration-based drug treatment programs have modest effects on criminal behaviour
  • PLS Description Many, if not most, incarcerated criminals are drug-dependent. In the absence of effective substance abuse treatment, a high proportion of these drug-dependent criminals will return to crime once released. Incarceration-based drug treatment programs allow correctional facilities to use force to encourage abusers to engage in treatment -- many of who otherwise would not do so -- as well as limit the availability of drugs with sufficient time available to focus on treatment and introspection. This review examines the effectiveness of incarceration-based drug treatment programs in reducing post-release recidivism and drug use.
