Healthy Start, Happy Start

Our Healthy Start, Happy Start research used a play-based video programme to support parents to interact with their babies and toddlers in a responsive and consistent way. So far, our study has shown that children whose families received the brief intervention when they were 1- and 2-years-old showed lower levels of behavioural problems up to two years later. We are currently following up with families now that their children are 7- to 9-years-old to see whether the programme had long-term impacts on children's behaviour and development.

In the Healthy Start, Happy Start study we’re looking at a programme that aims to help families understand their children’s behaviour by using videos of playful moments shared between caregivers and their little ones. We want to find out if this programme helps families deal with children’s tricky behaviours, and whether the programme is feasible to deliver as part of standard NHS services.

To do this, we invited 300 families with 1-2 year olds to take part in the Happy Start study. Families were put into one of two groups when they joined the study. They were either put into our programme group, where they were offered the play-based video programme we were interested in, or they were put into our monitoring group, where families carried on as normal, without receiving the programme.

We first visited all families at home when the study started. We then went back to see families again 5 months and 2 years after they first joined the study. Following all the families up helps us to see if receiving the programme made a difference to families. During these home visits, we collected information about children’s behaviour and communication, parenting, play, and early school experiences. In the first phase of the Happy Start study (running from 2015-2019), we found that children whose families received the programme when they were 1- and 2-years-old showed lower levels of behavioural problems two years later when they were aged 3-5.

A new phase of the Healthy Start, Happy Start began in PEDAL in early 2022. The Happy Start team are currently out visiting all 300 families now that their children are 7- to 9-years-old. This phase of the research will help us to understand how much of the initial impact of the programme is sustained and if families need additional support as their children grow.  It’s really special to have a group of children who we’ve been working with since they were so young. Happy Start families have made a really valuable contribution to one of the most unique studies of early childhood in the UK.
