Background and study aims
Research suggests that 'cash transfer' programmes – programmes in which families receive cash payments - have been found to improve social, mental and physical health outcomes for children, parents/carers and families. However, little is known about the impact of this type of support in England. This study aims to help understand this better and to find out whether giving families money to use however they want can improve young people’s wellbeing and mental health. This study focuses on families who receive support from social care services.

To provide strong evidence on the impact of these unconditional cash transfers, which is needed to justify this high-cost intervention, the research team is conducting a trial where families are allocated to one of two groups at random: one group of families receives both a new form of financial support (unconditional cash transfers) and their usual social care services, while a second group of families continues to receive only their usual social care services.

The research team also explores how the new form of financial support intervention improves children’s wellbeing, for example, whether the cash transfers reduce financial or family stress and improve families’ home life. Additionally, the team looks at how the intervention is carried out and if the intervention is done in the correct way. This includes checking whether the financial support is delivered as planned.

Who can participate?
Families who live in a participating local authority and have at least one child receiving social care support can take part in the study. This includes families with a Child in Need or a Child Protection Plan status who are eligible to receive financial support under Section 17 of the Children Act 1989.

What does the study involve?
Participating families are put into one of two groups at random: one group receives additional financial support while the other group, known as the control group, are offered no extra financial support. The families receiving the additional financial support receive weekly payments over 45 weeks. The control group receives their usual social services support and any pre-existing financial aid, such as Universal Credit, but no extra money.

The study is introduced to the families by local authority practitioners, such as their social worker. The participating parent-carer and their child are asked to complete up to three online surveys about their wellbeing, mental health, family functioning, financial circumstances, and home life — at the start of the study, and again at 4, 8, and 18 months after the family has been randomly allocated to a group. Both the parent-carer and the child receive a gift voucher for each survey they complete.

Some participating parents and carers are asked to take part in interviews to discuss their family experiences during the study. They are given a gift voucher as a thank-you for taking part. A group of local authority practitioners and staff involved in processing the payments is also invited to a focus group to discuss their experiences of the study.

What are the possible benefits and risks of participating?
Families taking part help the research team to understand the impact of unconditional cash transfers on families and ensure that everyone’s views are considered and different viewpoints heard. It’s unlikely that there are any risks to the family by taking part.

Where is the study run from?
The study is coordinated by The Anna Freud Centre in collaboration with King's College London, University of Exeter and University of Plymouth, and supported by participating local authorities to identify eligible families.

When is the study starting and how long is it expected to run for?
The study started in April 2025 and will end in August 2028, when the study team expects to report the results.

Study information

Primary study designInterventional
Study designMulticentre interventional randomized controlled trial
Secondary study designRandomised controlled trial
Study type Participant information sheet
Scientific titleA randomised controlled trial of a social care intervention
Study objectivesPrimary research question:
1. Is providing families with a child aged 10-16 under CiN/CPP with Unconditional Cash Transfers (UCTs), plus Business-as-Usual (BAU) services, more effective than BAU-only in reducing child-reported externalising behavioural difficulties (primary outcome)?

Secondary research questions:
Is providing families with a child under CiN/CPP with UCTs, plus BAU, more effective than BAU-only in improving:
1. Child-reported internalising difficulties?
2. Child-reported prosocial behaviour?
3. Child-reported impact of difficulties?
4. Child-reported family functioning?
5. Child engagement in education?
6. Child-reported substance use?
7. Child-reported time spent with caregivers?
8. Welfare concerns for the child?
9. Parent/carer-reported financial stress?
10. Parent/carer mental health and wellbeing?
11. Parent/carer-reported family functioning?

Is the impact of UCTs on the primary outcome explained (mediated) by changes in financial circumstances and one or more of the theorised pathways:
1. The Family Stress Model (e.g., parent-reported financial stress, parenting stress)?
2. The Resource Investment Model (e.g., housing quality, educational resources and opportunities, parent-child time spent together)?
3. Change in wider living environment (i.e., area-level deprivation)?

Is the impact of UCTs on primary and secondary outcomes, and mediators, different for families (moderated) according to:
1. Baseline level of income?
2. Level of state involvement?
3. Amount of cash received?
4. Number of children in the family?
5. Child gender and ethnicity?

Health condition(s) or problem(s) studiedMental health and wellbeing of children with social care input (i.e. Child in Need (CiN) or Child Protection Plan (CPP) status)
InterventionThe intervention group receives unconditional financial assistance in the form of cash. Each family receives payments for over 45 weeks. There are fixed dates for starting the intervention and receiving cash, and there is tapering near the end.

The control group (Business-As-Usual; BAU) receives all forms of service as they would were they not part of the trial. This includes financial or material support provided by local authorities via social workers' provision through s.17 of the Children Act 1989. It also includes existing community resources and financial capability support (e.g., accessing benefits, money management) provided by a range of statutory and third sector organisations. This is likely to be heterogeneous across participating areas.

All families in the trial can access existing financial/material support and financial capability support in line with the respective services’ eligibility criteria.

This study is a two-arm efficacy RCT: UCT + BAU vs. BAU only. Randomisation occurs at the individual child level, meaning that if a family has multiple children who meet the inclusion/exclusion criteria, one is selected (the youngest). A 1:3 allocation ratio (UCT + BAU: BAU only) is used to maximise power whilst keeping the intervention costs as low as possible, to enable the trial to be feasible.

IPD sharing plan summaryStored in non-publicly available repository
IPD sharing planThe datasets generated during the current study will be stored in a non-publicly available repository (The Youth Endowment Fund Evaluation Data Archive - https://youthendowmentfund.org.uk/evaluation-data-archive/)

At the end of the study (winter 2028), the research team will share the information gathered about all of the children who have taken part with the Department for Education (DfE). The DfE will replace all identifying information about the children who have taken part in the study (their name and date of birth) with the child’s unique Pupil Matching Reference number in the DfE’s National Pupil Database. The DfE will transfer this data to the Youth Endowment Fund (YEF) archive, which is stored in the Office for National Statistics’ Secure Research Service. The data in the archive is completely separate to any information that could identify participants, meaning the data is pseudonymised. The YEF is the ‘controller’ of the information in the YEF archive. By maintaining the archive and allowing approved researchers to access the information in the archive, the YEF is performing a task in the public interest and this gives the YEF a lawful basis to use personal information.

The YEF will keep information in the YEF archive for as long as it is needed for research purposes. Data protection laws permit personal information to be kept for longer periods of time where it is necessary for research and archiving in the public interest and for statistical purposes. The YEF will carry out a review every 5 years to assess whether there is a continued benefit to storing the information in the archive, based on its potential use in future research. Once information goes into the YEF archive it can no longer be deleted as that would affect the quality of the archived data for use in future research.
