Abstract
Data from Co‐SPACE and Co‐SPYCE studies was examined using mixed‐effect modelling and latent class growth (mixture) modelling. Parental stress and depression, but not anxiety, were higher during the periods of restrictions. Around three quarters of parents reported consistently low symptoms. Yet, a substantial minority reported consistently high or increasing mental health symptoms, including parents who were younger, single, had a pre‐existing mental health diagnosis or had a child with SEN or a neurodevelopmental disorder.
