Early positive approaches to support for families of young children with intellectual disability: the E-PAtS feasibility RCT

Background: Parents of children with intellectual disability are 1.5–2 times more likely than other parents to report mental health difficulties. There is a lack of clinically effective and cost-effective group well-being interventions designed for family carers of young children with intellectual disability. Aim: To examine the feasibility of a randomised controlled trial of the clinical effectiveness and cost-effectiveness of the Early Positive Approaches to Support (E-PAtS) intervention. Design: A feasibility study (including randomisation of families into a two-arm trial), questionnaires to assess the feasibility of proposed outcome measures (including resource use and health-related quality of life) and practitioner/family carer interviews. An additional question was included in an online UK survey of families, conducted by the research team to assess usual practice, and a survey of provider organisations. Setting: Families recruited from community contexts (i.e. third sector, local authority services, special schools) and self-referral. The E-PAtS intervention was delivered by trained community-based providers. Participants: Families with at least one child aged 1.5–5 years with an intellectual disability. At least one parent had to have English-language ability (spoken) for E-PAtS programme participation and participants had to provide informed consent. Interventions: E-PAtS intervention – two caregivers from each family invited to eight 2.5-hour group sessions with usual practice. Usual practice – other support provided to the family, including other parenting support. Objectives: To assess randomisation willingness/feasibility, recruitment of providers/parents, retention, usual practice, adherence, fidelity and feasibility of proposed outcome measures (including the Warwick–Edinburgh Mental Well-Being Scale as the proposed primary outcome measure, and parent anxiety/depression, parenting, family functioning/relationships, child behavioural/emotional problems and adaptive skills, child and parent quality of life, and family services receipt as the proposed secondary outcome measures). Results: Seventy-four families (95 carers) were recruited from three sites (with 37 families allocated to the intervention). From referrals, the recruitment rate was 65% (95% confidence interval 56% to 74%). Seventy-two per cent of families were retained at the 12-month follow-up (95% confidence interval 60% to 81%). Exploratory regression analysis showed that the mean Warwick–Edinburgh Mental Well-Being Scale well-being score was 3.96 points higher in the intervention group (95% confidence interval –1.39 to 9.32 points) at 12 months post randomisation. High levels of data completeness were achieved on returned questionnaires. Interviews (n = 25) confirmed that (1) recruitment, randomisation processes and the intervention were acceptable to family carers, E-PAtS facilitators and community staff; (2) E-PAtS delivery were consistent with the logic model; and (3) researchers requesting consent in future for routine data would be acceptable. Recorded E-PAtS sessions demonstrated good fidelity (96% of components present). Adherence (i.e. at least one carer from the family attending five out of eight E-PAtS sessions) was 76%. Health-related quality-of-life and services receipt data were gathered successfully. An online UK survey to assess usual practice (n = 673) showed that 10% of families of young children with intellectual disability received any intervention over 12 months. A provider survey (n = 15) indicated willingness to take part in future research. Limitations: Obtaining session recordings for fidelity was difficult. Recruitment processes need to be reviewed to improve diversity and strategies are needed to improve primary outcome completion. Conclusions: Study processes were feasible. The E-PAtS intervention was well received and outcomes for families were positive. A barrier to future organisation participation is funding for intervention costs. A definitive trial to test the clinical effectiveness and cost-effectiveness of E-PAtS would be feasible. Trial registration: Current Controlled Trials ISRCTN70419473.
