AimsThe aim of the study was to investigate teachers’ and pupils’ perceptions about the effect of the SafeSpot mental health curriculum on the well‐being of young people and on their knowledge of mental health conditions. This trial intends to determine the acceptability and benefits of web and mobile technology in delivering emotional well‐being in schools, through use of the SafeSpot programme.BackgroundWith 10% of young people aged 5 to 16 diagnosed with a mental disorder, there is pressure for schools to address their pupils’ emotional well‐being. However, many educators report that their schools have insufficient provisions and feel inadequately equipped to support pupils’ mental health.MethodsThis qualitative analysis was embedded within a randomly allocated stepped‐wedge design, conducted in six West of Scotland secondary schools. A total of 2320 pupils (aged 11 to 14 years) and 90 teachers were included. Young people’s understanding of health‐seeking, and teacher’s confidence in delivering and accessing well‐being information was assessed qualitatively.ResultsQualitative analysis revealed themes highlighting the beneficial nature of SafeSpot, including pupil engagement, content of tutorials, perceived impact of SafeSpot and level of training provided for teachers.ConclusionsWeb technology could potentially offer a more structured way for staff to support their pupils’ mental health, whilst reducing stigma. SafeSpot was perceived, by pupils and teachers, to be engaging.
