Emotional disorders are among the most common childhood mental health difficulties. The majority of adult emotional disorders begin before age 14 years. Most children and families across the population do not receive the proven evidence-based interventions available, particularly those from socially disadvantaged neighbourhoods and excluded, Black and Minoritised populations. Families from disadvantaged neighbourhoods, Black and minoritised communities can often feel judged, mistrustful, and blamed for their children's behavioural difficulties making them reluctant to engage in parenting supportEven when available, research shows that over one-third of parents receiving traditional specialist delivered evidence-based parenting do not gain the expected outcomes. Undertaking a group-based parenting intervention to help parents understand and deal with their children's anxiety issues. The aim of this study is to examine the feasibility and acceptability of a new parent-led parenting intervention, being a Parent Helping your Child (BAPHYC) that is intended to improve childhood anxiety and to use the findings to inform the planning and conduct of a definitive randomised control trial.

Being a Parent- Helping your Child (BAPHYC) has been developed from two well-established evidence-based parenting programmes. It is a parent-led, group format manualised parenting programme intended to improve childhood anxiety in children aged 5-12 years consisting of eight two-hourly weekly sessions peer-facilitated by two trained parent group leaders. The particants of BAPHYC participants are mothers, fathers and other carers who have principal parenting responsibility for a child with anxiety.

The specific study objectives are to:

1. Establish initial evidence about reach and engagement, delivery, acceptability and impact of BAPHYC
2. Establish the feasibility of proposed recruitment pathways and measure completion
3. Acquire a fine grain understanding of parents' experiences of the BAPHYC intervention, research procedures and themes arising from BAPHYC implementation.
4. Assess participant recruitment, engagement, intervention and measure completion, and intervention acceptability rates against a priori feasibility parameters.
5. Obtain data that will be used in future trial recruitment and planning.

Peer-led intervention models are a promising method for providing effective and acceptable parenting support to families considered hard to reach by mainstream services. Empowering Parents, Empowering Communities (EPEC) is an established parenting programme that involves recruiting and training local parents as "peer facilitators" to deliver manualised, evidence-based parent training groups in socially disadvantaged communities. EPEC optimises existing skills and relationship within local socially disadvantaged communities to deliver high quality, evidence-based parenting support for hard-to-reach families. Its group-based parenting course format is consistent with policy recommendations and intended to build social support between participants, optimise impact, and lower unit cost. EPEC is delivered in local, community locations and uses high visibility, pro-active local outreach campaigns to engage parents. Within these targeted community locations, an open access approach is typically used, rather than formal referral. To date, EPEC has focussed on increased scale of community-based care from birth to adolescence particularly in relation to behavioural and neurodevelopmental difficulties. Helping Your Child was developed by Cathy Creswell and Lucy Willetts from the University of Reading and University of Oxford, clinical psychologists with expertise in helping children with anxiety problems. The philosophy of the programme is the belief that parents, and carers are the experts when it comes to their child. They will have a better understanding of how their own child might respond and what will encourage and motivate them to try different things than a therapist will have.

As such, the central aim of the programme is to provide strategies for parents and carers that they can use at home to support their child for them to overcome problems with anxiety. Achieved by increasing parents' confidence in their ability to help their child overcome anxiety. As such, the philosophy of the programme is non-blaming and one that highlights positive skills and responses of parents, to build their confidence and empower them to support their children. The programme has been delivered and evaluated on an individual basis (i.e., one-to-one), and in response to demand a group programme manual that can be consistently delivered in a group format. The integration of these two foundational programmes combines EPEC's expertise in task-sharing delivery methods, reach to vulnerable and marginalised communities and wider parenting expertise with Helping your Child with Fears and Worries specialised expertise in the use of parent adjunct treatments methods for childhood anxiety.

These foundational programmes share similar theoretical foundations (of attachment, social learning and systems theory and intervention procedures (highly interactive, adult learning models, focussed skill acquisition and in vivo practice). Belsky's Multiple Determinants of Parenting (MDP) Process Model, provides the most used explanatory framework of the ecological and subjective influences on parenting and child outcomes. MDP posits that child developmental trajectories are influenced by the interaction between the child's inherent characteristics, the parenting of primary carers, the characteristics of the parent/primary care givers, the family and social environment, and wider social and economic factors. To impact on child behaviour and conduct outcomes, realistic intervention targets, based on MDP, for a psychosocial group-format parenting intervention such as EPEC include parenting, parent well-being and mental health. Family and social; encourage strategies to increase family consistency and household stability, reduce household chaos and impact of chronic stressors and social and economic such as improvements in child behaviour, parenting confidence and practices, and family functioning.

The new intervention, BAPHYC, developed from these two well-established evidence-based parenting programmes EPEC Being a Parent and Helping Your Child, is intended to provide specifically tailored parenting support to parents and other primary caregivers of children who have anxiety problems. The intervention's group-format offers the potential opportunity for participant parents and other caregivers to reduce isolation, stigma and increase social support from parents and caregivers experiencing similar problems. A peer-led, task transfer model potentially increases problem normalisation and validation, motivation for change and reduce stigma for marginalised parents and caregivers. Before undertaking a larger and costlier study it is necessary to demonstrate the viability of the novel BAPHYC intervention and associated research by testing the design and delivery of the intervention, its acceptability, and the logistics of recruitment, delivery, and data collection.

Feasibility studies are pieces of research done before a main study to answer the question "Can this study be done?" They are used to estimate important parameters that are needed to design the main study, but do not evaluate the outcome of interest; that is left to the main study.

Inclusion Criteria:

• Parent/ primary caregiver, including non-biological caregiver, for index child aged 5-12 years.
• Parent-reported difficulties and concerns in managing anxiety of an index child. In households with more than one child aged 5-12 years, we ask the parents to nominate an index child whose behaviour was of greatest concern.
• Parent/ primary caregiver must have proficient written and spoken English.
• Parent/ primary must have capacity to provide informed consent to participate.

Exclusion Criteria:

Families where the parent/ parental caregiver:

• The nominated index child of the parent/ primary caregiver has a primary neurodevelopmental condition such as autism, for which parent is likely to require specialist parenting intervention.
• The parent / primary caregiver is unable to attend weekly course sessions of the BAPHYC intervention.
• The parent / primary caregiver is not living with the index child and is unlikely to have sufficient contact to implement parenting skills acquired during the BAPHYC intervention.

Parent or parental caregiver including non-biological caregiver, for index child aged 5-12 years

This is a feasibility study; process evalaution with a small, but targeted recrutiment sample set. We will only be looking at mechanisms of reach, engagement and delivery and completion rates. No planned detailed analysis of effect sizes will be conducted. We will share the protocol and participant information sheets.
