The evidence that IPS works

IPS is the most extensively researched approach to employment support.

Research about IPS started in the mid-1990s, when day treatment programmes were converted to employment support services. By 2008, 11 randomised controlled trials had been completed, enough to conduct a systematic review. A 2008 review established that the success rates of IPS programmes could be replicated across different contexts and countries.

In 2016 a meta-analysis of 17 IPS randomised controlled trials from 10 countries again demonstrated the success of IPS services.

These consistent effects across time, different populations and countries show the robustness of the IPS approach, which has been operating successfully in New Zealand for over 10 years.
