The SHINE online pupil mental health survey was developed in 2019. This survey for pupils from P6 to S6 asks young people about different aspects of their mental health: (i) subjective wellbeing (ii) mental health problems and (iii) positive mental health. The survey also includes other key topics that we know are associated with good overall health and wellbeing, such as sleep and school engagement. Each academic year, pseudonymised survey responses are collated into a national dataset.
