Cuts to benefits and wider economic hardship are increasing demand for mental health care, NHS bosses say.
Mental health leaders in England cited the rollout of universal credit, in particular, as a key factor. They also said money problems and job worries alongside social factors, such as loneliness, were adding pressure to an already stretched system.
The government acknowledged there were "challenges" in reforming benefits, but said it was tackling them.
A spokesman also stressed that mental health services were a "key priority" for the boost in funding to the health service in the coming years.
He said the extra £2.3bn being invested by 2023 would increase the proportion of the budget spent on mental health.
'We're not complacent though and we know that change won't happen overnight," he added.
The way the government is overhauling the benefits system has attracted criticism.
A new system called universal credit is currently being rolled out. It involves the merger of six different benefits for working age people into one monthly payment.
While the system, first introduced in 2013, was supposed to be up and running by 2017, it is now not expected to be fully operational until 2023.
However, it has been criticised for running over budget, causing delays to people's payments and, in some cases, making vulnerable people worse off.
The government said it was "making improvements" to the system as it was rolled out, but said universal credit would simplify the system and "tailor support" better to help those most in need.
However, NHS Providers deputy chief executive Saffron Cordery said her members were clear that "social and economic pressures are translating into higher demand for services".
She said the feedback showed that rising demand was causing problems as services struggled with staff shortages.
This meant there were insufficient services in the community and patients needing hospital-based care were at risk of being sent away from their home areas.
The mental health bosses provided feedback to their trade body NHS Providers.
The group asked bosses from mental health trusts to answer questions via an online survey.
A total of 35 bosses answered questions about economic and social factors from nearly 60% of England's dedicated mental health trusts.
The benefits system and the changes being made were said to be increasing demand by 32 trusts.
Meanwhile, 34 cited financial hardship, 33 homelessness and 31 job instability as factors.
Wider social issues, such as a lack of local services and loneliness were also highlighted by many.
