The British Preschool-Children's Play Survey, 2023, was designed to correspond in part with the British Children's Play Survey, conducted in 2020 (see SN 8793). The questions focused on children's play, screen time and mental health. For play, caregivers reported the time children spent playing in seven locations and the corresponding adventure levels. Caregivers then also reported the amount of time their child spent on screens for recreational and educational purposes and completed measures of their children's affect and mental health, as well as their own mental health. Data were collected via a survey conducted with a nationally representative sample of 1,166 parents/caregivers of children aged 2-4 years (52% male; 88% White), living in Britain.  Preschool children's play; preschool children's screen use; wellbeing; parent wellbeing; childcare.
