The work comes from the Auditor General for Scotland and the Accounts Commission.
Accessing adult mental health services in Scotland remains slow and complicated for many people, auditors have warned.
A new report on adult mental health services by the Auditor General for Scotland and the Accounts Commission claims ethnic minority groups, people living in rural areas and those in poverty all face additional barriers.
There have been big funding increases for services since 2017, but a lack of data makes it hard for the Scottish Government to see the impact of that spending. Waiting times for psychological therapies have improved.
But ministers do not measure the quality of wider mental healthcare services, or whether they are improving people’s health.
The mental healthcare system is fragmented, the report claims - with the Scottish Government, NHS boards, councils, Integration Joint Boards, Health and Social Care Partnerships and the third sector all involved in funding, planning or providing services.
They said this makes accountability complex and causes complications and delays in developing care focused on the needs of individuals.
Stephen Boyle, Auditor General for Scotland, said: “The Scottish Government needs much more information to understand the difference its investment in mental health services is making, from specialist services to community-based support.
“That planning must include moving beyond using waiting times as the sole measure of whether services are improving the lives of those in need. And it needs to include a costed delivery plan for the care that people can expect in their communities.”
The Scottish Government plans to increase its Mental Health Directorate budget by 25 per cent and ensure that ten per cent of the front-line NHS budget is spent on mental health by 2026.
They have also committed to giving all GP practices access to community based mental health and wellbeing services.
These commitments are essential to improving access to services and relieving pressure on the mental health workforce. But ministers’ plans are not on track.
Ronnie Hinds, interim chair of the Accounts Commission, said: “Councils and Integration Joint Boards have a vital role to play in improving the availability and quality of data needed to plan services and get the right levels of staffing in place.
“They also need urgently to develop shared goals and targets to improve how housing, welfare and other services work together in order to address and prevent the root causes of poor mental health.”
