A briefing by the NIHR Mental Health Policy Research Unit (MHPRU) at University College London (UCL) and King’s College London (KCL) finds that Individual Placement and Support employment services and Housing First support for homeless people both have robust evidence of their effectiveness in supporting people with mental health difficulties into work and homes respectively. There is also clear evidence that social security policies have a major impact on people with mental health difficulties: policies that restrict access to benefits or reduce entitlements worsen people’s mental health and vice versa.
